second, it is necessary to observe whether the particles in the cross section of the ceramic tile are fine or not. Consumers should pay attention to the fact that the transverse plane mentioned here does not refer to the cutting plane around the tile, but refers to the fracture of the tile fragment. Generally speaking, the top grade is fine, hard and brittle, and the color is consistent. Because the ceramic tiles with fine particles have strong waterproof ability; However, the ceramic tiles with larger particles are easy to be immersed by moisture, which affects the quality.
Third, pay attention to the thickness of the glaze layer. The glazed surface of ceramic tile is what we call the whole surface of ceramic tile, and the thickness of glazed layer is the thickness of the cross section of glazed surface. Glaze is the most expensive material in the cost of ceramic tiles. The thicker the glaze layer, the better the natural quality.
fourth, listen. Tap the tile and listen to the sound. If the sound is clear and pleasant, it is the top grade, if the sound is dull, it is the inferior product.
five 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 marks left by the front water are obvious. Tiles that soak slowly after water is dispersed have high density, and the water marks are not obvious, which is regarded as top grade.
6. Take two bricks back to back and face to face to see if they can be in close contact with each other, and if there is too large a gap, you can judge whether there is warping.
VII. Find ink and scrub it for an hour to see if there are any traces. If there are no traces, it is a good brick. If there is infiltration, it is definitely not selected.
VIII. Take two bricks to measure the geometric dimensions of the two bricks, and if there is no deviation in the dimensions of the bricks diagonally, it is an excellent product.
IX. Refer to the test report issued by the national or industrial testing authorities provided by the merchants and compare the following index data: water absorption, wear resistance, acid resistance and pollution.
question 2: the choice of tiles, how do you see the quality of tiles? There are many introductions on the Internet, but there are many omissions in some things. Today, I would like to introduce how to identify the quality of tiles with some simple methods combined with legends, hoping to help you! ! !
mainly through "see, weigh, listen, spell, try" several simple methods to choose! The details are as follows:
The first point: seeing
mainly refers to seeing the surface quality of ceramic tiles. Here, it is introduced in terms of glazed tiles and vitrified tiles:
1. Glazed tiles:
mainly depends on whether there are surface defects such as black spots, bubbles, pinholes, cracks, scratches, stains, missing edges and corners on the surface of ceramic tiles! The quality of bricks with many defects is relatively poor!
2. Vitrified brick:
In addition to seeing whether there are surface defects such as black spots, bubbles, pinholes, cracks, scratches, colored spots, missing edges and corners on the surface of vitrified brick, we should also pay attention to whether there are defects such as missing polishing and missing grinding.
No matter what brand the product is, the blank should have the brand mark of the ceramic tile. Check the trademark mark of the blank. The blank of the product produced by regular manufacturers has a clear product trademark mark. If there is none or it is particularly vague, it is recommended to choose carefully!
the second point: to weigh
means to weigh the components, and to test the feel of the tiles. For the products of the same specification, the tiles with good quality and high density feel heavier, whereas the products with inferior quality feel lighter.
the third point: listen to
distinguish the quality of tiles by tapping tiles and listening to sounds. According to kitchen and bathroom wall tiles, wall tiles or small-sized tiles
generally, one hand and five fingers are used to separate tiles, and the other hand is used to tap the face of tiles. If the sound is metallic, the quality of tiles is better. If there is no sound with metallic texture, the quality of tiles is worse!
For large floor tiles (floor tiles such as living rooms are vitrified tiles or antique tiles), lift one side of the tile with one hand, and tap the middle of the tile with the upper part of the palm of the other hand. If the sound is rich and the echo is as long as the sound of tapping a bronze bell, the tile has a high degree of porcelain, strong wear resistance, high flexural strength, low water absorption and is not easy to be polluted. If the sound is cloudy and there is no echo, the degree of porcelain is low (even exists. The fourth point: splicing
Take out four pieces of products with the same specifications and models at random, and splice them. Through this step, we can check the three aspects of tile size, flatness and straight angle.
(1) Check the size of ceramic tile
Take two pieces of products of the same model out on the horizontal plane, and slide back and forth along the edge of the ceramic tile with the tips of both hands. If there is no obvious feeling of hand stagnation when passing through the sealing part of the ceramic tile, it means that the size of the ceramic 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 hand-stuck tiles, it means that the size error of tiles is large, which will affect the effect of paving!
(2) Check the flatness of 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 tile surface by hand. If there is no obvious sense of height after passing through the joints of tiles, it means that the flatness of tiles is good. On the contrary, it means that the flatness of tiles is poor, which will affect the overall effect of tile paving. If the flatness of tiles is poor, people will be tripped in serious cases! So this should attract attention.
(3) At present, most tiles are rectangular, and each corner of the tile is right-angled. If the straight angle is poor, it will also affect the paving effect of the tile. Take four tiles of the same model and splice them. If four tiles can't be closely jointed, there is always a gap in one or two joints, which shows that the straight angle of the tile is not particularly good.
fifth point: try
As long as it is aimed at the anti-slip problem of floor tiles, the materials are mainly divided into vitrified and glazed. For the anti-slip problem of tiles now, the common practice is to add water to the tile surface and then step on it to see if it is slippery. This practice is actually not entirely appropriate, because some tiles, especially vitrified tiles, will feel more foot-related after adding water. If you want to open the glass, it is very difficult, because water squeezes out the air in the middle, making the brick and the vamp contact more closely, so it feels more foot-related, while some vitrified bricks feel slippery without adding water. In this regard, my personal suggestion is to try both steps of adding water and not calling water!

question 3: how to judge the quality of ceramic tiles? Mainly through "see, weigh, listen, spell, try" several simple methods to choose! The details are as follows:
1. Look at
mainly to see whether there are black spots, bubbles, pinholes, cracks, scratches, color spots, missing edges and corners on the surface of ceramic tiles, and also to pay attention to whether there are defects such as missing throwing and grinding. Check the trademark mark of the bottom embryo. The bottom embryo of the products produced by regular manufacturers has a clear product trademark mark. If there is none or it is particularly vague, it is recommended to choose carefully!
second, weighing
means weighing the weight, testing the feel of tiles. For products of the same specification, bricks with good quality and high density feel heavier, on the contrary, inferior products feel lighter.
III. Listening
By tapping the tiles, the quality of the tiles can be identified by listening to the sound. Here are two aspects of kitchen and bathroom tiles and vitrified tiles:
Tapping method:
1) Wall tiles or small-sized tiles
Generally, one hand is used to separate the tiles, and the other hand is used to tap the tile face. If the sound is metallic, it is tiled. As shown in the following figure:
2) Large floor tiles (the living room and other floors are vitrified tiles or antique tiles)
Lift one side of the tile with one hand, and tap the middle of the tile with the upper part of the palm of the other hand. If the sound is thick and the echo is as long as the sound of tapping a bronze bell, the tile has a high degree of porcelain, strong wear resistance, high flexural strength, low water absorption and is not easy to be polluted. If the sound is turbid, it will be difficult to be polluted.
IV. Splicing
Take out four pieces of products with the same specifications and models at random and lay them together. Through this step, we can check the three aspects of tile size, flatness and straight angle.
1) Check the size of ceramic tile
Take two pieces of products of the same model out on the horizontal plane, and slide back and forth along the edge of the ceramic tile with the tips of both hands. If there is no obvious feeling of hand stagnation when passing through the sealing place of the ceramic tile, it means that the size of the ceramic 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 hand-stuck tiles, it means that the size error of tiles is large, which will affect the effect of paving!
2) Check the flatness of 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 tile surface by hand. If there is no obvious sense of height after passing through the joints of tiles, it means that the flatness of tiles is good. On the contrary, it means that the flatness of tiles is poor, which will affect the overall effect of tile paving. If the flatness of tiles is poor, people will be tripped in serious cases! Therefore, we should pay attention to this point. For example,
3) The problem of the straight angle of tiles
At present, tiles are mostly rectangular, and each corner of tiles is right-angled. If the straight angle is poor, it will also affect the tile paving effect. Take four tiles of the same model and splice them. If four tiles can't be closely jointed, there is always a gap in one or two joints, which shows that the straight angle of tiles is not particularly good.
5. Try
It is mainly aimed at the anti-slip problem of floor tiles
For floor tiles, the materials are mainly divided into vitrified and glazed. For the anti-slip problem of tiles now, it is common practice for everyone to add water to the tile surface and then try it on it to see if it is slippery. This practice is actually not entirely appropriate, because some tiles, especially vitrified tiles, will This principle is a bit similar to adding water between the glasses. If you want to lift the glass, you will find it very difficult, because the water squeezes out the air in the middle and makes the brick and the vamp contact more closely, so it feels more foot-related, while some vitrified bricks feel slippery without adding water. In this regard, my personal suggestion is to try both steps of adding water and not calling water!
question 4: what are the precautions in choosing ceramic tiles? How to see good or bad? Look at the material, surface smoothness, three-dimensional sense of design and color, surface smoothness, and whether the sideline is not deformed < P > Question 5: How do you think the floor tiles are good or bad? Common floor tiles are: vitrified tiles, polished tiles, inferior smooth brick, glazed tiles, printed tiles, non-slip tiles, and special acid-proof floor tiles.
The quality of floor tiles is very professional, so please pay attention to:
First, check whether the green color of tiles is pure. This trick is very simple, mainly to observe whether the color of the back of the tile is uniform and consistent. 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 ceramic tile are fine or not. Consumers should pay attention to the fact that the transverse plane mentioned here does not refer to the cutting plane around the tile, but refers to the fracture of the tile fragment. Generally speaking, the top grade is fine, hard and brittle, and the color is consistent. Because the ceramic tiles with fine particles have strong waterproof ability; However, the ceramic tiles with larger particles are easy to be immersed by moisture, which affects the quality.
Third, pay attention to the thickness of the glaze layer. The glazed surface of ceramic tile is what we call the whole surface of ceramic tile, and the thickness of glazed layer is the thickness of the cross section of glazed surface. Glaze is the most expensive material in the cost of ceramic tiles. The thicker the glaze layer, the better the natural quality.
fourth, listen. Tap the tile and listen to the sound. If the sound is clear and pleasant, it is the top grade, if the sound is dull, it is the inferior product.
5. 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 marks left by the front water are obvious. Tiles that soak slowly after water is dispersed have high density, and the water marks are not obvious, which is regarded as top grade.
6. Take two bricks back to back and face to face to see if they can be in close contact with each other, and if there is too large a gap, you can judge whether there is warping.
VII. Find ink and scrub it for an hour to see if there are traces. If there are good bricks without traces, they will not be selected if there is infiltration.
VIII. Take two bricks and measure the geometric dimensions of the two bricks. If there is no deviation in the dimensions of the bricks diagonally, it is an excellent product.
IX. You can refer to the test report issued by the national or industrial testing agency provided by the merchants and compare the following indicators: water absorption, wear resistance, acid resistance and pollution.
International famous brands: Bee, Nobel, Diamond, Eagle and Asia
Domestic famous brands: Crown Pearl, samit and Golden Rudder
Price: several yuan/block-1 yuan/block
Question 6: How can we see the tiles from the surface? You have to test the quality yourself. Be sure of yourself.
inspection method:
1. It can be knocked, and the crisp sound indicates that the porcelain density and hardness of the tile are high and the quality is good
(if the tile is tapped lightly by hand, if it makes a poof, poof sound, it indicates that its sintering degree is not enough and its texture is inferior. If it makes a slight knocking sound, its texture will be harder than the previous one.
(Actually, the method is very simple. Knock it by hand, and the high-density ceramic tile will knock out with the crisp smell of glass. The low-density tiles make a dull tile sound. )
2. Measure the water absorption rate of ceramic tiles. The lower the water absorption rate, the higher the inherent stability of ceramic tiles, and the more suitable it is for spaces with high moisture or moisture content (such as bathrooms and kitchens), so that problems such as black spots will not occur
3. Pour a glass of water on the back of ceramic tiles, and the water stains will spread rapidly, indicating that the water absorption rate is high, and vice versa. 4. Scrape the glazed surface of ceramic tiles with a hard object. Explain that the quality is poor
5. See if the color of the tile is clear, and look with the naked eye for pinholes, which are easy to accumulate dirt
6. The flatness of the tile is flat, the side is straight, it is easy to spread, and the effect is good (visual method, put the tile on a flat surface to see if its four edges are completely consistent with the flat surface, and at the same time see if the four corners of the tile are right angles, Then put the tiles in the same variety and model to observe the degree of color difference.)
7. When choosing a tile, you often see the material supplier stepping on the ground, which only shows that the bottom of his tile is flat and can't be said to be
clear.
