Indoor floor tiles are:
Vitrified tiles, polished tiles, inferior smooth brick, glazed tiles, printed tiles, non-slip tiles, and special acid-resistant floor tiles (used in laboratories and other corrosive floors).
Outdoor floor tiles include: square tiles and lawn tiles.
Family:
Ultra-fine powder belongs to the series of vitrified tiles (porcelain polished tiles), and the raw material particles of the blank used are ground to be very small (generally above 150 mesh), which are randomly distributed by computer, calcined at high temperature and high pressure and polished on the surface. Also called micropowder.
Polycrystalline micropowder is made by melting some crystal frits in the sintering process on the basis of micropowder, which can also be said to be an upgraded product of micropowder brick.
Super bright and clean is the first product of New Zhongyuan Ceramics. By forming a unique dense protective layer on the surface of ceramic tile, the pores left after polishing can be effectively filled, infiltrated into the brick body, and closely combined with the brick blank to prevent the infiltration of super stains.
Floor tiles can generally be divided into polished tiles, vitrified tiles, glazed tiles and mosaics.
Polishing brick
At present, it mainly refers to porcelain bricks made by polishing their surfaces to produce mirror effect by using their high hardness and wear resistance. The types of polished tiles mainly include: ordinary polishing, solid color polishing, infiltration polishing, free cloth polishing, micro-powder polishing, large particle polishing, full particle polishing and other series.
Polished tiles are made of clay and stone powder by pressing and firing with a press. The front and back are the same color. After glazing and firing, the surface is polished, so that the front is bright and the back is the true color of the brick. Because it is polished, it is not resistant to dirt. There will be water marks after being dragged with a mop. The second disadvantage is that polished tiles are not slippery because they are smooth. The third problem is that colored liquids are easy to penetrate. However, a good brand is not easy to penetrate because of its good pressure, high density, high firing temperature and high density, but this is not absolute. No matter how good the polished brick is, if the ink or soy sauce is accidentally dropped on it for a few minutes and then wiped, it will inevitably leave traces that will never be wiped off, because the stain has penetrated into the brick.
Vitrified brick,
Also known as glass fossils and bricks, the professional name should be porcelain glass fossils. It is made of quartz sand and mud according to a certain proportion, and then polished with professional abrasives, and the surface is smooth and transparent like a glass mirror. In the practice and understanding of marketing staff, the author knows that vitrified bricks are superior to ordinary glazed tiles and ordinary marble in water absorption, edge straightness, flexural strength, acid and alkali resistance, etc., and because many of these bricks have the color of imitation marble and the texture distribution is more consistent and symmetrical than natural marble, they are deeply loved by spiders.
However, the vitrified brick is not perfect, and its defect is that the pores are exposed after grinding, and dust and oil are easy to penetrate. Many users should find that the vitrified brick is as bright as a mirror when they buy it. After a long time, the existing stains will penetrate into it, and the result is difficult to remove. At present, this is a recognized problem in the industry, but some manufacturers have solved this problem through new technologies after research. Before leaving the factory, the products should be treated with anti-fouling treatment to block pores and prevent dirt from infiltrating. However, it does not mean that all manufacturers of this kind of products have this anti-pollution treatment process, because this process is not included in the national standard of this kind of products. Many brands of products can be sold as qualified products without anti-pollution treatment, and consumers do not know the situation. If they are not careful when laying, stains will appear. Ask the spider before you buy it. If the vitrified brick without antifouling treatment needs to be waxed in use, ordinary floor wax can be used. Before paving, in order to avoid damage to the brick surface during construction, finished product protection should be done well.
The difference between vitrified brick and polished brick;
First of all, it is certain that vitrified tiles belong to polished tiles. It's just that its manufacturing process is higher than that of polished tiles in the ordinary sense. Vitrified brick refers to completely fired brick, that is, all-ceramic ceramic products. At present, the polished tiles usually mentioned in the market refer to ordinary polished tiles, that is, the porcelain of the brick body is poor, which belongs to ceramic products that are not completely burned. The biggest difference between polished brick and vitrified brick lies in the degree of porcelain, that is to say, vitrified brick has higher hardness, higher density and lower water absorption. (The water absorption of vitrified brick is less than or equal to 0. 1%). The antifouling performance of vitrified brick is much higher than that of ordinary polished brick.
Scope of application of vitrified tiles and polished tiles: living room, bedroom, walkway, etc.
Glazed tiles:
As the name implies, the surface is fired with glaze, and the main body is divided into mud and porcelain. The back of fired clay is red, and the back of fired porcelain is gray. The surface of glazed tiles can be made into various patterns and patterns, which are richer than polished tiles. Because the surface is glazed, the wear resistance is not as good as polished tiles.
Generally speaking, it is made by firing the ceramic tile blank at a certain temperature, and then glazing the ceramic tile surface at high temperature and high pressure. It consists of a ceramic tile blank and a thin glaze layer on the surface. Glaze layer is mainly to increase the aesthetic effect of ceramic tiles, and at the same time play a role in antifouling. According to different glazes, glazed tiles are divided into two types: matt and bright. Matte: the reflection principle belongs to diffusion, the surface is a little rough and uneven, and the light feeling is soft; Bright light belongs to the reflection principle, and the brick surface is smooth and bright.
The kitchen should use bright glazed tiles. Although there is a thin layer of glaze on the matte glaze, it is not difficult to scrub it, but after a long time, the glaze of the tile will inevitably fall off, and at this time, oil stains will enter the surface of the tile, which is difficult to clean.
Parameters of high quality glazed tiles:
(1) water absorption: it should not be greater than 2 1%.
(2) Quenching and heating resistance: Quenching and heating resistance refers to the performance of glazed tiles that can withstand sharp temperature changes without cracking. The temperature difference between hot and cold used in the test should be about 65438 030 degrees Celsius.
(3) Bending strength: the average bending strength of glazed tiles is not less than 16Mpa, and when the brick thickness is greater than or equal to 7.5mm, the average bending strength is not less than 13Mpa.
(4) Crack resistance: According to the crack resistance test, there is no crack on the glaze.
(5) Chemical corrosion resistance of glaze: Chemical corrosion resistance of glaze refers to the corrosion resistance of glaze under the action of acid-base solution. The chemical corrosion resistance of glaze is generally determined by both supply and demand. There are no special requirements for home use.
All-ceramic mirror polished floor tile (the surface of polished tile is coated with a layer of antifouling agent and filled with pores, which ensures that it is not easy to be polluted, wear-resistant, easy to scrub, and has high density. After paving, the overall effect is as bright as a mirror, but the high brightness has a slight impact on people's vision, and the antifouling effect is worse than that of glazed tile. The service life is about 8 years, which is not suitable for the living environment of the elderly). Commonly used 800*800 is suitable for living room floor paving. The price of medium quality is generally around 50-60 yuan.
Printed infiltrated floor tiles (service life is about 7 years, scratches will appear) are usually 800*800, which is suitable for living room floor paving. The price of medium quality is generally around 30-40 yuan.
Matte floor tiles (economical but with low surface strength, low density and easy to leave stains, etc.) are commonly used. The price of 600*600 medium quality tiles is generally within 10 yuan.
Non-slip floor tiles (for toilet use) are generally 500*500. The price of medium quality is generally within a piece of 5 yuan.
When selecting bricks:
First, it sounds crisp rather than boring.
Second, whether two bricks can be in close contact back to back and face to face, if the gap is too large, it can be judged whether they are warped.
Third, find the ink on the surface and scrub it for an hour to see if there are any traces. If there is no trace, it is a good brick. If there is infiltration, resolutely do not choose.
Fourthly, take two bricks and measure their geometric dimensions, length and width. If there is no deviation in the diagonal dimension of the brick, it is a superior product.
5. Open a package of unopened bricks on site and compare the color difference with the sample. No color difference is the best.
Ceramics with water absorption less than 0.5% are called vitrified tiles or polished tiles, and polished tiles are actually similar products. The lower the water absorption, the better the vitrification degree and the better the physical and chemical properties of the product.
There is a layer of glaze on the surface of glazed tile, which is actually a layer of glass. It does not absorb water and dirt, but the polished tile surface has fine pores, which are easy to absorb pollutants.
When choosing floor tiles, you can compare the following indicators: water absorption, wear resistance, acid resistance and pollution indicators.
The choice of glazed tiles mainly depends on the treatment of ceramic tires and glazed surfaces. Ceramic tires shall be standard in size, flat in periphery and uniform in thickness, and the difference between the thickness and size of ceramic tiles of the same specification shall not exceed 2mm. The quality of glaze is more critical. First of all, enamel should be thick and smooth; Secondly, the glaze color difference should be as small as possible. Toilets and bathrooms are suitable for laying small-sized tiles.
2, look at the product appearance
Randomly select several tiles from the packing box to check whether the surface of the product has the following defects, such as ripples, spots, glaze bubbles, bumps, cracks, lack of glaze, etc. Generally, the visual distance from the tile is 3 meters, and the defects are not obvious, which does not affect the use of qualified products. There is a tile trademark on the back of each tile, and adhesive accessories are not allowed on the back and side.
Look at the size
Need to check the specifications one by one. Products with dimensional error greater than 0.5 cm and flatness greater than 0. 1 cm will not only increase the construction difficulty, but also have poor effect after decoration and cannot be used in construction.
See chromatic aberration
Because tiles are purchased at one time, if there is obvious color difference, the decoration effect will be greatly affected. Therefore, all packaged products should be sampled and compared to observe the color difference changes, and the ones with large color difference should not be selected. You should also pay attention to whether the color of each box of tiles is the same
Listen to the sound of tiles
Distinguish the internal quality of ceramic tiles, which is invisible by sight, and can be distinguished by sound by tapping. The method is: drag a tile with both hands, and tap another tile with a corner of one tile, which makes the sound crisp and loud and the quality is better.
● Seamless laying has many disadvantages.
At present, many users pursue the beauty of tile laying and use seamless paving. Experts in the industry pointed out that the expansion and contraction of the base layer, the adhesive layer and the tile itself are very different when paving the floor tile. Under the cold and hot stress damage of 1-2 years, the tile is prone to seamless bulging and fracture. However, the ratio of the cost of repaving after such problems to the cost of first paving is about 4: 1.
Experts also pointed out that leaving seams can save tiles, and when the seam is 1 mm-3 mm, it can save about 3% of materials; It is convenient to adjust the tile spacing according to the actual paving area, so that the tiles can be used at the corners as much as possible, which is both beautiful and time-saving and labor-saving; There is a telescopic space for joint paving, which is easy to ensure the smoothness of tile surface and avoid joint deviation caused by brick shape or size deviation, which will affect the overall effect of tile paving; It can avoid the deformation, arching, hollowing and fracture of the brick body caused by the different shrinkage rates between the brick body and the ground or wall.
