How to identify the quality of ceramic tiles?

1. Look at the hardness - ceramic tiles with high hardness are not easy to damage and have a long service life. In the process of selecting tiles, tap the tiles to listen to whether the sound is crisp, the more brittle the sound, the higher the texture density of the tile, the better the hardness.

Second, the size of the measurement - the standard size of a tile has clear regulations, if we measure the brick after the results and the value of the product is different, it means that such products are inferior products. The size of the size of the product is inspected one by one, the size error is greater than millimeters, and the flatness is greater than millimeters, which will not only increase the difficulty of construction, but also greatly reduce the effect after decoration.

3. Water absorption rate - high-quality wall and floor tiles have a very low water absorption rate. When purchasing, if the wall and floor tiles do not indicate the water absorption rate, you can put the reverse side of the tile on the ground, sprinkle some water on the back of the wall and floor tile, and observe the diffusion degree of the water droplets after a few minutes to identify the advantages and disadvantages of the tiles: if the water droplets spread quickly, it means that the water absorption rate is high and the texture of the tiles is poor.

Fourth, specific weight - pick up two different brands of tiles, in the case of similar size and thickness, the lighter one is of poor quality, and the heavier one is a good brick.

Fifth, the price comparison - the current market ceramic tile height difference is very large, from tens of yuan per square meter to one or two hundred yuan; The price of some imported ceramic tiles is higher, which is basically 1-2 times higher than that of domestic ceramic tiles. However, industry insiders said that the intrinsic quality gap of these tiles is not as big as the price gap. Therefore, although you get what you pay for, don't be blindly superstitious, the quality of the product is more critical, and there is no need to spend high costs in order to blindly pursue foreign imported brands.

Sixth, the glaze measurement - when testing, with a sharp object to scratch the tile glaze to see if there are scratches, if there is, it means that this kind of tile glaze is poor, after the surface of the glaze polished, the brick surface will not be able to be cleaned. On the contrary, it shows that this kind of glazed brick is glazed better, wear-resistant and practical.

7. Test the slip resistance - the specific method is to put a few floor tiles flat on the ground, sprinkle some water, and step on them to feel it. If it is really a non-slip product, then there will be an astringent feeling under the feet. And slipping under the foot proves that it is not a true anti-slip product.

8. Chromatic difference - ceramic tile color difference refers to the difference in color and pattern of ceramic tile products due to the production process. Due to the large number of wall and floor tiles purchased at one time, if there is obvious color difference between multiple packages, the decoration effect will be very affected, so it is necessary to sample and compare all packaged products and observe the changes in color difference.

How to choose tiles:

Home decoration should buy tiles, how to buy value for money, satisfactory tiles also have a certain knowledge, in general the principle of buying tiles is: a look, two listens, three drops of water, four feet.

First, look at the appearance.

The color of the tile should be uniform, the surface finish and flatness should be good, the surrounding rules should be regular, the pattern is complete, and four or five pieces should be extracted from a box to see if there are defects such as color difference, deformation, lack of edges and corners.

2. Listen to the sound.

Tap with a hard object, the crisper the sound, the higher the degree of porcelainization, and the better the quality. You can also use the thumb, index finger and middle finger of the left hand to clip the corner of the tile, hang down easily, and tap the middle and lower part of the tile with the index finger of the right hand.

3. Drip test.

You can drop water on the back of the tile to see how fast the water soaks after it spreads, generally speaking, the slower the water absorption, the greater the density of the tile; On the contrary, the faster the water absorption, the sparse density, and its intrinsic quality is superior.

Fourth, the measurement. The higher the accuracy of the side length of the tile, the better the effect after paving, and buying high-quality tiles is not only easy to construct, but also can save man-hours and accessories. Use a tape measure to measure whether there is a difference in the size of each tile, and the high accuracy is the top grade.

In addition, observe its hardness, ceramic tiles with good hardness, strong toughness, not easy to break and rot as the top quality. The edges and corners of the tile fragments are scratched on each other, and the broken fragments are inspected to see whether the broken parts are fine or loose, whether they are hard, brittle or soft, whether they leave scratches, or scattered powder.

Whether the size is standard is the key to judging the quality of the tile, measure the diagonal and quadrilateral size and thickness of the tile with a tape measure or caliper, whether the thickness is uniform, good tile, the sound is brittle, indicating that the porcelain content is high. If the sound is "clicking" with the sound of stubble, it means that there are cracks hidden in the brick.

Good tiles, the master installation is also convenient for construction, and the effect of installation is also standardized.

1) Glaze: Carefully glaze, the glaze should be smooth and delicate; (2) Chromatic aberration: put several ceramic tiles together, carefully inspect under the light, and the chromatic aberration of good products is very small.

The color difference between the products is basically the same: the color difference of the poor products is larger, and the shades are different; (3) Porcelain: The color and chromaticity of ceramic tiles are clear and natural, indicating a high degree of porcelainization; If the chromaticity is not clear, the porcelain degree is low; (4) Color:

The pattern should be delicate and realistic, without obvious defects such as lack of color, broken thread, and dislocation; (5) Water absorption: drop a few drops of tea juice or water on the back of the tile, after a few minutes, depending on the degree of inhalation and diffusion of water droplets, the quality is good if it does not absorb water or has a low water absorption rate; (6) Hardness: knock on the tile to listen to whether the sound is crisp, the more brittle the sound, the higher the porcelain degree and density, and the better the hardness; (7) Abrasion resistance:

Scratch the tile with a sharp object, observe whether it has scratches, if there are scratches, it means that the glaze has poor wear resistance, easy to make people slip, and after the glaze on the surface is polished, the brick surface will not be able to be cleaned; (8) Glazed pinholes: When purchasing, observe whether there are pinholes on the surface with the naked eye within one meter, if there are, it means that the glaze is not completely integrated, and it is easy to accumulate dirt; (9) Flatness: whether the side of the tile is straight with the naked eye, if the warping situation is serious, it will affect the firmness of the tile paving in the future; (10) Dimensional deviation:

The specifications of ceramic tiles can be measured with calipers, and the deviation of good product specifications is small, and the products are neatly drawn after paving.

First, the brick joints are straight and the decorative effect is good; Poor product specifications deviate greatly, and product sizes are different; (11) color selection: the tone of the exterior wall tiles should be in harmony with the surrounding environment, and high-rise buildings are generally not suitable for white or too light-colored exterior wall decorative bricks to avoid the lack of texture of the building: in the interior decoration.

The tones of floor tiles and interior wall tiles should be coordinated with each other; (12) The selection of ceramic tile types: tiles should be selected according to the specific environment of use, such as polished tiles or antique tiles of larger specifications should be used in the living room, and the kitchen and bathroom should be best selected non-slip and easy-to-clean full-body tiles.

In life, ceramic tiles are needed in the decoration of the home, and the quality of the tiles will directly affect the overall effect of the home decoration in the future. Therefore, it is very important to buy your own tiles strictly. Currently, there are many brands of tiles on the market.

What about usHow to identify the *** bad of tiles

First, how to identify the best bad ceramic tiles.

1. Observe the appearance of the tiles.

To see if the surface finish and flatness of the tile are good, the rules and the surrounding pattern are complete, we can take four or five tiles to observe, to see if there is a color difference, edge deformation or missing corners and other defects.

2. Listen to the sound.

Gently pat with a hard object. If the sound is clear, then the *** of the tile. You can also grab the corners of the tiles with your fingers and hang them easily.

Then, use your right index finger to touch the center part of the tile. If the sound is clear and pleasant, the quality is good. For example, the voice is deaf and hoarse.

If there is a "click" in the deactivated sound, there is a crack in the brick. Therefore, ceramic tiles are also suitable for installation and construction, and the installation effect is also very beautiful.

3. The drip irrigation test is early.

You can put some water and place it on the back of the tile to see how quickly the water soaks in. In general, the slower the water absorption, the denser the tile; In other words, if the water is absorbed quickly, the density of the tile is low, so the higher the density, the better the quality of the tile.

How to identify the *** bad of tiles？-Quantity.

Whether the size is standard is the key to judging the advantages and disadvantages of ceramic tiles. Use a tape measure or ruler to measure the width of the four sides as well as the diagonal and thickness of the tiles. If the precision of the tile length is higher, the effect after paving will also be greater.

The best thing is that branded tiles are not only easy to make, but also save construction time and the use of accessories.

<> "Kind of identification of the *** bad of the tile.

1. Look. Looking at the appearance, the simple way is to see whether it is flat and neat, whether there are bubbles and impurities on the surface, how the corner division process is, whether it is twisted, warped and defective, etc. Najan.

Looking at the color, the color of the tile can see whether the firing temperature is uniform and how the technical device is. Usually the gloss of ceramic tiles of brand manufacturers is better than that of ordinary manufacturers.

Look at the color difference, put several tiles together, pay attention to see if the color difference is obvious, there is no color difference.

Look at the thickness, stack several bricks vertically together, and check whether the thickness is uniform from the side.

2. Listen. Grab one of the corners of the tile with the left hand, let it hang down naturally, and hit the lower middle and lower position of the tile with the index finger of the right hand. If the sound is dull and the sound of being empty is made, it means that the proportion of the material is not right, or the firing heat is not well controlled, the porcelain performance is insufficient, the hardness of such tiles is insufficient, and it is easy to break, so it is not recommended to buy.

3. Knock. It is the weight, the same specification and type of tile, the handle is large, usually better. That kind of ceramic tile has a sufficient amount of ceramic powder, high density, and is very strong.

4. Dripping. Put a few drops of tap water on the back of the brick and see how well it absorbs. If the water absorption is fast, it means that the density of the tile is insufficient, the quality is ordinary, and the tile is not suitable for use in the kitchen, bathroom and other places with heavy moisture.

On the contrary, the slower water absorption means that the density of the tile is higher, and the quality of the tile is better.
