Secondly, the internal quality of ceramic tiles, first look at the water absorption rate: drop a drop of water on the brick to see the speed of water seepage. Good tiles, water droplets will roll on the tiles. Listen to the sound again: good tiles, crisp sound, indicating high porcelain content. If the sound is "click" and stubble breaks, it means that there is a crack in the brick.
Selection method of ceramic tile
When decorating a house, you should buy tiles. There is also some knowledge about how to buy value-for-money and satisfactory tiles. Generally speaking, the principle of choosing ceramic tiles is: look, listen, three drops of water and four feet.
First look at the appearance. The color of ceramic tiles should be uniform, the surface smoothness and flatness should be better, the periphery should be regular and the pattern should be complete. Take out four or five pieces from a box to see if there are any defects such as color difference, deformation and lack of edges and corners.
Second, listen to the sound. Tap with a hard object, the clearer the sound, the higher the porcelain degree and the better the quality. You can also hold a corner of the tile with your left thumb, forefinger and middle finger and hang it down easily. Tap the middle and lower part of the tile with the index finger of your right hand. If the sound is crisp and pleasant, it is the top grade; if the sound is dull and stagnant, it is the inferior grade.
Third, the dripping test. You can drop water on the back of the tile to see seepage velocity after the water is dispersed. Generally speaking, the slower the water absorption, the greater the density of tiles; On the contrary, the faster the water absorption, the rarer the density and the better the internal quality.
Fourth, the ruler. The higher the accuracy of the side length of ceramic tile, the better the effect after paving. Buying high-quality tiles is not only convenient for construction, but also saves working hours and accessories. Measure the size and periphery of each tile with a tape measure, and the one with high accuracy is the top grade.
In addition, observing its hardness, the ceramic tile is top grade, with good hardness, strong toughness and no breakage. Scrape each other with the edges and corners of tile fragments to see whether the broken fragments are fine or loose, brittle or soft, leaving scratches or loose powder. If the former is top grade, the latter is poor quality.
Brief introduction of tile varieties and three-step code of brick selection
At present, there are many kinds of ceramic tiles on the market, such as permeable tiles, vitrified tiles and non-slip tiles, which can usually be divided into the following categories.
Glazed tile: refers to the ceramic tile with glazed surface. This kind of brick is divided into two categories: first, it is fired with clay. Because of its high water absorption, it must be glazed, so it should be called "ceramic tile" accurately. This kind of brick has low strength and is rarely used now; The other is fired with porcelain clay. In order to pursue decorative effect, glaze is also fired. This kind of ceramic tile has compact structure, high strength, low water absorption and strong anti-pollution ability, and its price is slightly higher than that of ceramic tile fired by porcelain clay. Glazed tiles fired by porcelain clay are widely used in home decoration at present, and 80% buyers use this tile as floor decoration material. The trick to distinguish these two kinds of bricks is simple: the back of the ceramic tile fired by clay is red, and the back of the ceramic tile fired by porcelain is white. Among the ceramic tiles fired with clay, the wall and floor tiles produced in Spain are very popular in Beijing at present because of their unique decorative effect, but the price of this kind of brick is relatively high, and it is generally used for middle and high-grade home decoration.
Full-body brick: this is a kind of unglazed porcelain brick with good anti-slip and wear resistance. Generally speaking, what we call "non-slip floor tiles" are all-in-one bricks. This kind of brick is moderately priced and very popular with consumers. Among them, the exquisite pattern of "flower infiltrated brick" is even more attractive.
Polished brick: The whole brick becomes polished brick after polishing. This kind of brick has high hardness, so it is very wear-resistant.
Vitrified brick: this is a kind of porcelain brick fired at high temperature, which is the hardest of all tiles. Sometimes polished tiles are scratched, but vitrified tiles are still safe and sound. But this kind of brick is expensive, so it is not necessary to use it for home decoration. Ceramic tiles can be divided into floor tiles, wall tiles and waist tiles according to their functions.
There are many kinds of floor tiles, and there is a lot of room for choice. According to the color, it can be divided into glazed tiles, non-slip tiles, glazed tiles and polished tiles. Although the names are quite different, there is little difference in processing technology and composition. The common size of floor tiles is 400 ~ 600 mm square format, and sometimes even large-format floor tiles of 1000× 1000mm are used. & gt
Question 2: How to distinguish the quality of ceramic tiles? How to distinguish the quality of ceramic tiles? This method can be basically divided into:
First, check whether the green color of the tiles is pure. This trick is very simple, mainly to observe whether the color on the back of the tile is uniform. The tiles with better quality have uniform and symmetrical body color.
Second, it is necessary to observe whether the particles in the cross section of the tile are fine or not. What consumers need to pay attention to is that the transverse plane mentioned here does not refer to the cutting plane around the tile, but refers to the fracture of the tile fragments. Generally speaking, the top grade is fine in texture, hard and crisp, and the color is consistent. Because the fine-grained tiles have strong waterproof ability; However, the tiles with larger particles are easily soaked by moisture, which affects the quality.
Third, pay attention to the thickness of glaze layer. The glazed surface of ceramic tile is what we call the whole surface of ceramic tile, and the thickness of glazed surface is the thickness of glazed cross section. Glaze is the most expensive material in ceramic tile cost. The thicker the glaze layer, the better the natural quality.
Fourth, listen. Tap on the tile and listen to the sound. If the sound is crisp and pleasant, it is top grade, if the sound is dull, it is inferior.
Fifth, we must test the water. Consumers can pour some water on the back of the tile, and pay attention to the speed at which the tile absorbs water. After a few minutes, see if the traces left by the accumulated water in front are obvious. The tiles slowly soaked after water dispersion have high density and inconspicuous water marks, which are regarded as top grade.
6. Take two bricks back to back and face to face to see if they can be in close contact. If the gap is too large, it can be judged whether there is warping.
Seven, find the ink on the surface and then scrub it for an hour to see if there are traces. If there is no trace, it is a good brick. If there is infiltration, resolutely do not choose.
Eight, take two bricks to measure the geometric size, length and width of two bricks, and look at the dimensional deviation of bricks sideways. No deviation is the best product.
9. You can refer to the test report issued by the national or industrial testing institutions provided by the merchants and compare the following indicators: water absorption, wear resistance, acid resistance and pollution indicators.
I recommend several famous ceramic tile brands to you: American ceramic tile, Dong Peng floor tile, Shunhui ceramic and Eagle brand ceramic. The product quality is good.
Question 3: How to choose tiles? How to see the quality of ceramic tiles? There are many introductions on the Internet, but there are many omissions in some things. Today, I will introduce how to identify the quality of ceramic tiles with some simple methods combined with legends, hoping to help you! ! !
Mainly through "look, weigh, listen, spell, try" several simple methods to choose! Details are as follows:
Number one: Look.
See mainly refers to check the surface quality of ceramic tiles, the following according to glazed tiles and vitrified tiles to introduce two aspects:
1, glazed tile:
Mainly depends on whether there are surface defects such as black spots, bubbles, pinholes, cracks, scratches, stains and lack of edges and corners on the surface of ceramic tiles! Bricks with many defects are of poor quality!
2, vitrified brick:
In addition to seeing whether there are surface defects such as black spots, bubbles, pinholes, cracks, scratches, stains, lack of edges and corners on the surface of vitrified bricks, we should also pay attention to whether there are defects such as missing polishing and grinding.
No matter what brand the product is, the blank must have the brand logo of ceramic tile. Check the trademark mark of the blank. The product blanks produced by regular manufacturers have clear product trademark identification. If it is not or particularly vague, it is recommended to choose carefully!
Number two: OK.
It is to weigh and test the feel of tiles. For products of the same specification, bricks with good quality and high density feel heavier, whereas inferior products feel lighter.
The third point: Listen.
By tapping the tiles and listening to the sound, we can identify the quality of the tiles. There are kitchen and bathroom tiles, wall tiles or small-sized tiles.
Generally, use one hand to separate the five fingers, pull up the tile, and use the other hand to hit the tile surface. If there is metal sound, the quality of tiles is better, but without metal sound, the quality of tiles is poor!
For larger tiles (tiles such as living room are vitrified tiles or antique tiles), lift one side of the tile with one hand, and tap the upper part of the palm of the other hand on the middle of the tile. If the sound is rich and the echo is as long as the sound of knocking a copper bell, the ceramic tile has a high degree of porcelain, strong wear resistance, high flexural strength and low water absorption, and is not easy to be polluted. If the sound is turbid and there is no echo, the porcelain is low (even cracked). The fourth point: fighting.
Randomly take out four products of the same specification and model and put them together. Through this step, we can check the size, flatness and right angle of the tile.
(1) Check the size of the tiles.
Take out two products of the same model and put them on a horizontal surface, and slide back and forth along the edge of the tile with your fingertips. If there is no obvious hand lag when passing through the sealed part of the tile, it means that the size of the tile is better and the error is small. The smaller the size error, the better the tile paving effect will be! On the contrary, if there is an obvious feeling of sticking tiles by hand, it means that the size error of tiles is large, which will affect the effect of paving!
(2) Check the flatness of ceramic tiles.
Lay two or four tiles of the same model on a flat surface according to the same lines, and slide back and forth on the surface of the tiles by hand. If there is no obvious sense of height after passing through the joint of the tile, it means that the flatness of the tile is better. On the contrary, it shows that the flatness of ceramic tiles is poor, which will affect the overall effect of tile paving. If the flatness of the tile is poor, it will trip people seriously! So this should attract attention.
(3) The right angle of ceramic tile is rectangular, and every corner of ceramic tile is right angle. If the right angle is poor, it will also affect the tile paving effect. Take four tiles of the same model and splice them together. If four tiles can't fit closely, there is always a gap in one or two joints, indicating that the right angle of the tiles is not particularly good.
Fifth point: try
As long as it is aimed at the anti-skid problem of floor tiles, the materials are mainly divided into vitrification and glaze. For the anti-slip problem of ceramic tiles, the usual practice is to add water to the surface of ceramic tiles, and then step on it to see if it slips. This practice is actually not entirely appropriate, because some tiles, especially vitrified tiles, will feel more related to their feet after adding water. This principle is somewhat similar to adding water between glasses. If you want to open the glass, because the water squeezes out the air in the middle, the brick and the vamp are in closer contact and feel more full, while some vitrified bricks feel slippery without water. My personal suggestion is to try both adding water and not calling water!

Question 4: What are the criteria for evaluating the quality of ceramic tiles? Which walls pay attention to horizontal and vertical? The internal and external angles must be 90 degrees, the flatness shall not exceed 2mm, and the vertical angle shall not exceed 2mm. Special seam shall not exceed 2mm (based on non-pulling seam). To use aluminum alloy rods to clamp the wall, it is necessary to be seamless, not to mention the internal and external angles. Be sure to tighten it. Unless there is too little cement ash or the soaking time is short, you can't knock on the wall.
Except for the special edge area of 100, there shall be no empty drum at the bottom; 10.
Question 5: How to distinguish the quality of ceramic tiles? One two three four five six.
Weighing: weigh the bricks by hand, and the bricks with heavy hand feel have high density and hardness; On the contrary, it is even worse.
Scraping: try to scrape the glaze with hard objects. If scratches appear, it means that the glaze quality is not good and the hardness is not enough. In this case, after the glazed surface is polished, the brick surface is easy to hide dirt and shelter evil people, and it is difficult to clean.
Tap: Tap the surface of ceramic tile with your hand. If the sound is crisp and loud, it means that the tiles are of good quality and ripe; If the sound is abnormal, it means that the sintering in the tile is not good and there may be internal cracks.
Look: look at the section, look at the surface, look at the color. Section density should be high; Surface reflectivity should be natural; The more color changes, the more harmonious the application, which is suitable for large-scale overall paving and creates a harmonious aesthetic effect. Of course, it must match the overall style of the home.
Drip: The simplest operation to test water absorption is to drip water on the back of the tile. Products with low water absorption and good internal quality will not be soaked or diffused by water droplets, and vice versa. The water absorption rate of ceramic tiles is below five thousandths, and the tiles are compact and of good quality.
Painting: scribble on the front of the tile with a colored pen and wipe it with a wet cloth later. If the light is as bright as new, leaving no trace, it means that the ceramic tile has strong pollution resistance and is easy to take care of.
Ming? Sheng? Tao? I hope I can help you.
Question 6: How to see the quality of ceramic tiles from the surface? It is suggested to visit the building materials market more, try to choose the brand of ceramic tiles, and the quality is guaranteed. You have to test the quality yourself. Have confidence in yourself.
Inspection method:
1. It can be knocked, and the sound is crisp, indicating that the tile has high density, high hardness and good quality.
Tap the floor tile with your hand. If the tile makes a poof, poof sound, it shows that its sintering degree is not enough and its texture is poor. If it makes a slight tapping sound, its texture will be harder than the previous one)
(In fact, the method is very simple. Knocking by hand, high-density tiles knock out the crisp taste of glass. Low-density tiles make a dull tile sound. )
2. Measure the water absorption of ceramic tiles. The lower the water absorption rate, the higher the inherent stability of ceramic tiles, and the more suitable for spaces with high water content (such as bathrooms and kitchens), so that there will be no problems such as black spots.
3. Pour a glass of water on the back of the tile, and the water stain will spread rapidly, indicating that the water absorption rate is high, and vice versa.
4. You can scrape the glaze of ceramic tile with hard objects. If traces are left, the quality is poor.
5. See if the color of the tile is clear, and see with the naked eye whether there are pinholes, which are easy to scale.
6. The flatness of the tile is flat on the side, easy to spread, and good in effect (visual method, put the tile on a plane to see if its four sides are completely consistent with the plane, and at the same time see if the four corners of the tile are at right angles, and then put the tile on the same variety and model to observe its color difference).
7. When choosing a floor tile, it is often seen that the material supplier tramples on the ground hard, which only shows that the bottom of his floor tile is flat and cannot be said.
The tiles in Mingta are of good quality.
8. Draw on the ground. Because of the high density, the poor tile is completely like a piece of chalk, and there are marks everywhere.
9. The first point is to look. Look at the grade. Excellent products are the best, and third-class and inferior products are worrying; Second, look at the appearance and glaze color.
noodle Good tiles have no problems such as convexity, concavity and warping, and the edges are flat. Glaze is smooth, without particles or different shades of color.
Elephant; Third, look at the pattern. The pattern should be delicate, without obvious color leakage, dislocation, broken line or different shades.
10. The second point is listening. Hold a corner of the tile with the thumb, forefinger and middle finger of one hand and hang it easily. Tap the porcelain with the forefinger of the other hand.
In the middle and lower part of the brick, if the sound is crisp and pleasant, it is the top grade, if the sound is dull and turbid, it is the defective product.
1 1. Cut off the ceramic tile fragments (generally, you can look for the fragments that the store wants to break) to see the broken parts. The crack is fine, hard and brittle,
The same color is top grade.
12. When the water drops drop on the back of the tile, the tile that is slowly wetted after the water is dispersed has a high density and is regarded as the top grade.
13. In addition to your favorite color, you should also choose carefully: first, take out any four tiles from the box and put them on a flat ground to compare whether the four tiles are flat and consistent and whether the diagonal parts of the tiles are embedded. Then tap the surface of the tile with your palm and listen to the sound: a good tile has a lower sound; The sound of broken tiles is bright and has obvious echo. Of course, judging from the sound is relative. However, the first comparison method should not be underestimated. The biggest difference between domestic bricks and imported bricks mainly lies in the consistency of ceramic tile product specifications.
14. Look at the glaze of the brick, and the surface of the tile should be smooth and delicate; High-gloss glazed tiles should be crystal clear, and matt and semi-matt glazes should be
Soft and even reflection. Try scraping the tile surface with a hard object. If scratches appear, it means that the glaze is insufficient and the surface glaze is polished.
After that, the brick surface is easy to hide dirt and accept dirt, and it is difficult to clean. Second, to see if the product size is standard, you can use calipers to measure diagonal lines and irregularities.
When paving, the tiles will not be in a straight line, resulting in unsightly. Third, looking at the deformation, you can directly observe with the naked eye and see that the edge of the product is flat.
In this way, the deformation of the product is small, the construction is convenient, and the brick surface is smooth and beautiful after paving. Fourth, look at the pattern, the design should be delicate and realistic, no
There are obvious defects such as lack of color, broken line and dislocation.
Look at the packaging. First of all, identify the factory name, address and trademark to avoid buying "three noes" products. Secondly, look at the product quality grade and water absorption. Generally speaking, the lower the water absorption, the higher the strength and the better the frost resistance. If users buy tiles mainly for paving or outdoor walls, they need to buy products with low water absorption, such as porcelain tiles or stoneware tiles. If the bricks purchased by users are mainly used for indoor walls, such as kitchen and bathroom walls, you can choose products with high water absorption, such as ceramic tiles. But it needs reference ... >>
Question 7: How to distinguish the quality of ceramic tiles? First of all, we must decide what style of tiles to buy. At present, there are roughly two styles on the market: antique tiles and polished tiles. Pay attention to the following points when buying;
1. Look at the back of the brick to see if its color is pure. Generally, the solid color is milky white (white, but not very white), and there can be no black, yellow or black spots on the surface, indicating that there are impurities in the tile itself, and more impurities affect the density and quality; Too white is abnormal because zirconium silicate is used too much.
2. See if the particles on the side of the tile are fine and uniform. If the particles are large and rough, and the brick density is crisp, there will definitely be problems in the use process.
3. Erect the ceramic tile and tap the brick body with your hand. The crisper the sound, the higher the brick density and the better the quality. The duller the sound, the worse the density of tiles, and the worse the anti-pollution ability of tiles.
If you buy polished tiles, you can touch the front of the tiles by hand. The smoother the handle, the less pinholes there are on the brick surface, and the higher the anti-pollution ability. Of course, it is best not to use this kind of brick in the bathroom and kitchen, and pay attention to anti-slip.
5. Look at the gloss of the same color brick surface. The clearer the shadow, the higher the gloss of the brick, the stronger the hardness of the brick and the higher the durability. On the contrary, the more blurred the shadow of the light bulb, the lower the hardness of the brick.
6. If you buy antique bricks, touch the front of the brick body with your hands. Feel whether the glaze on the brick surface is delicate with your hands, and then carefully observe whether the glaze particles are rough with your eyes. When buying antique bricks, we must pay special attention to the quality of glaze.
7. If you buy ceramic tiles (wall tiles), it depends on the gap between the blank and the glaze on the side of the brick and the thickness of the glaze.
Question 8: How to distinguish between good and bad tiles? There are five grades of ceramic tiles, which are marked by grades, namely, excellent, first-class, second-class, third-class and foreign. As the prices vary greatly, we need to compare them carefully. In addition, when purchasing, we should also pay attention to whether the signs, specifications and color numbers on the tiles and the packaging boxes are consistent, and whether the product certificate, trademark and quality inspection label are clear. Depending on the size of the specifications, it is not only conducive to construction, but also reflects the decorative effect. Good specification deviation is small, uniform after paving, straight brick joints and good decorative effect. Products with dimensional error greater than 0.5 mm and flatness greater than 0. 1 mm will not increase the construction difficulty, and the effect after decoration will be poor. Whether the size is up to standard can be judged by the target. Put the brick on the plane to see if its four sides are completely consistent with the plane, and at the same time see if the four corners of the tile are at right angles. It is good to report that there are no defects such as concave-convex, bulging, warping, etc., and the error of side length is not more than 0.2-0.3mm, and the error of thickness is not more than 0.1mm. The higher the accuracy of the side length of ceramic tile, the better the effect after paving. Buying high-quality tiles is not only convenient for construction, but also saves working hours and accessories. Measure the size and periphery of each tile with a tape measure, and the one with high accuracy is the top grade. Hardness ceramic tile is a top grade with good hardness, strong toughness and non-fragile. Scrape each other with the edges and corners of tile fragments to see whether the broken fragments are fine or loose, brittle or soft, leaving scratches or loose powder. If the former is top grade, the latter is poor quality. Whether the size is standard or not is the key to judge the quality of ceramic tiles. Use a tape measure or caliper to measure whether the diagonal and four sides of the tile are consistent in size and thickness. A good ceramic tile has a crisp sound, indicating a high porcelain content. If the sound is "click" and stubble breaks, it means that there is a crack in the brick. Good tiles are easy to be installed by the master, and the installed effect is standardized. Ceramic tiles with good patterns have clear and consistent patterns and colors, exquisite craftsmanship, and no obvious color leakage, dislocation, disconnection or inconsistency in depth. The color difference of color-difference tiles is directly related to the decoration effect. Not a batch of products, or the same batch may produce color difference. Therefore, in the process of purchasing, it is necessary to sample and compare each packaged product, put the tiles in the same variety and model of bricks, and observe the degree of color difference. Good products have little color difference, the colors between products are basically the same, the colors are bright and even, and they are radiant, while poor products have large color difference and different shades. The color of ceramic tiles should be uniform, the surface smoothness and smoothness should be good, the periphery should be regular and the pattern should be complete. Take out four or five pieces from a box to see if there are any defects such as color difference, deformation and lack of edges and corners. Listen to the sound and tap with a hard object. The crisper the sound, the higher the porcelain degree and the better the quality. You can also hold a corner of the tile with your left thumb, forefinger and middle finger and hang it down easily. Tap the middle and lower part of the tile with the index finger of your right hand. If the sound is crisp and pleasant, it is the top grade; if the sound is dull and stagnant, it is the inferior grade. Dropping test can drop water on the back of ceramic tile to see seepage velocity after water dispersion. Generally speaking, the slower the water absorption, the greater the density of tiles; On the contrary, the faster the water absorption, the rarer the density and the better the internal quality.
Question 9: How to distinguish the quality of ceramic tiles? First, look at hardness-tiles with high hardness are not easy to be damaged and have long service life. In the process of choosing tiles, tap the tiles and listen to whether the sound is crisp. The crisper the sound, the higher the texture density and the better the hardness of the tile.
Second, size measurement-the standard size of ceramic tiles is clearly defined. If the result obtained after measuring the brick body is different from the value indicated in the commodity, it means that this product is inferior. Check the specifications one by one, and the products with dimensional error greater than 0.5 mm and flatness greater than 0. 1 mm will not only increase the construction difficulty, but also greatly reduce the effect after decoration.
Third, water absorption-high-quality wall and floor tiles, water absorption is very low. When purchasing, if you don't indicate the water absorption rate of the wall and floor tiles, you can put the back of the tiles on the ground, sprinkle some water on the back of the wall and floor tiles, and after a few minutes, you can distinguish the advantages and disadvantages of the tiles by observing the diffusion degree of water droplets: if the water droplets spread quickly, it means that the water absorption rate is high and the texture of the tiles is poor.
Fourth, the proportion-pick up two different brands of tiles. In the case of similar size and thickness, the light quality is poor, and the heavy brick is good.
Verb (abbreviation of verb) price comparison-the price of ceramic tiles on the market at present varies greatly, ranging from tens of yuan to one or two hundred yuan per square meter; However, the asking price of some imported tiles is higher, which is basically 1-2 times higher than that of domestic tiles. However, according to industry sources, the internal quality gap of these tiles is not as big as the price gap. Therefore, although a penny is worth a penny, don't blindly believe in the price. Product quality is more critical. There is no need to spend a lot of money blindly pursuing foreign imported brands.
Six, glaze measurement-detection, use a sharp object to scrape the glaze of ceramic tiles to see if there are scratches. If there is, it means that the glaze of this kind of tile is poor. After the glazed surface is polished, the dirty tile surface will not be cleaned. On the contrary, it shows that this glazed tile is glazed well, wear-resistant and practical.
Seven, try the anti-skid degree-the specific method is to spread a few floor tiles on the ground, sprinkle some water, and step on it to feel it. If it is really a non-slip product, then there will be a feeling of astringency under your feet. Slipping at the foot proved not to be a real anti-skid product.
Eight, color difference-ceramic tile color difference refers to the difference in color and pattern of ceramic tile products due to production technology. Due to the large one-time purchase of wall and floor tiles, if there is obvious color difference between multiple packages, the decoration effect will be greatly affected. Therefore, it is necessary to sample and compare all the packaged products to observe the change of color difference, and the ones with large color difference cannot be selected.
Question 10: How to judge the quality of ceramic tiles? Mainly through "look, weigh, listen, spell, try" several simple methods to choose! Details are as follows:
First of all, look
Mainly depends on whether there are black spots, bubbles, pinholes, cracks, scratches, stains, lack of edges and corners on the surface of ceramic tiles, and also pays attention to whether there are defects such as missing polishing and missing polishing. Check the trademark mark of the bottom embryo. The bottom embryo of products produced by regular manufacturers has clear product trademark identification. If it is not or particularly vague, it is recommended to choose carefully!
Second, weigh it.
That is to say, weigh and try the feel of the tiles. For products of the same specification, bricks with good quality and high density feel heavier, while inferior products feel lighter.
Third, listen
By tapping the tiles and listening to the sound, we can identify the quality of the tiles. The following are two aspects of kitchen and bathroom tiles and vitrified tiles:
Knocking method:
1) wall tiles or small tiles
Generally, separate the five fingers with one hand, drag the tile upwards, and tap the tile surface with the other hand. If the sound is metal, the quality of tiles is better. As shown in the figure below:
2) Large floor tiles (the living room and other floors are glazed tiles or antique tiles)
One hand lifts one side of the tile, and the upper part of the palm of the other hand taps the middle of the tile. If the sound is rich and the echo is as long as the sound of knocking a copper bell, the ceramic tile has a high degree of porcelain, strong wear resistance, high flexural strength and low water absorption, and is not easy to be polluted. If the sound is turbid and there is no echo, the porcelain degree is low (even there are cracks), the ceramic tile blank is not fully calcined, the wear resistance is poor and the flexural strength is low.
Fourth, fight.
Randomly take out four products of the same specification and model and put them together. Through this step, we can check the size, flatness and right angle of the tile.
1) Check the tile size.
Take out two products of the same model and put them on a horizontal surface, and slide back and forth along the edge of the tile with your fingertips. If there is no obvious hand lag when passing through the sealed part of the tile, it means that the size of the tile is better and the error is small. The smaller the size error, the better the tile paving effect will be! On the contrary, if there is an obvious feeling of sticking tiles by hand, it means that the size error of tiles is large, which will affect the effect of paving!
2) Check the flatness of ceramic tiles.
Lay two or four tiles of the same model on a flat surface according to the same lines, and slide back and forth on the surface of the tiles by hand. If there is no obvious sense of height after passing through the joint of the tile, it means that the flatness of the tile is better. On the contrary, it shows that the flatness of ceramic tiles is poor, which will affect the overall effect of tile paving. If the flatness of the tile is poor, it will trip people seriously! So we should pay attention to this, as follows
3) The right angle of the tile.
At present, the tiles are mainly rectangular, and each corner of the tiles is a right angle. If the right angle is poor, it will also affect the tile paving effect. Take four tiles of the same model and splice them together. If four tiles can't fit closely, there is always a gap in one or two joints, indicating that the right angle of the tiles is not particularly good.
Five, try
Mainly aiming at the anti-skid problem of floor tiles.
As far as floor tiles are concerned, materials are mainly divided into vitrified tiles and glazed tiles. For the anti-slip problem of ceramic tiles, it is common practice to add water to the surface of ceramic tiles and then step on it to see if it is slippery. In fact, this practice is not entirely appropriate, because some tiles, especially vitrified tiles, will feel more involved after adding water. This principle is somewhat similar to adding water between glasses. If you want to open the glass, it's hard to find it. Because the water squeezes out the air in the middle, the brick and the upper are in closer contact and feel more full, while some vitrified bricks feel slippery without water. My personal suggestion is to try both adding water and not calling water!
