How to use some simple methods to identify the quality of ceramic tiles: mainly through a few simple methods of "looking, weighing, listening, spelling, and trying" to choose! The specific introduction is as follows: 1. The main inspection is to check whether there are black spots, bubbles, pinholes, cracks, scratches, stains, missing edges and missing corners on the surface of the ceramic tiles. Also pay attention to whether there are missing polishing, Defects such as leakage and grinding. Check the trademark mark on the bottom blank. Products produced by regular manufacturers have clear product trademark marks on the bottom blank. If there is no one or it is particularly blurry, it is recommended to choose carefully! 2. Weigh is to weigh the weight and test the feel of the ceramic tiles. For products of the same specifications, bricks with good quality and high density will feel heavier. On the contrary, inferior products will feel lighter. 3. Listening By tapping the tiles, you can identify the quality of the tiles by listening to the sound. The following is introduced in terms of kitchen and bathroom wall and floor tiles and vitrified tiles: Tapping method: 1) Wall tiles or small-sized tiles are generally made with a Spread the fingers of one hand apart, drag up the tile, and tap the face of the tile with the other hand. If the sound is metallic, the quality of the tile is better. As shown below: 2) Large floor tiles (vitrified tiles or antique tiles are used on floors such as living rooms). Use one hand to lift one side of the tile and tap the middle of the tile with the upper part of the other hand. If the sound is thick and If the echo is as long as the sound of striking a copper bell, the ceramic tile has a higher degree of porcelain, strong wear resistance, high flexural strength, low water absorption, and is not easily contaminated. If the sound is turbid and there is no echo, the degree of porcelain is low ( There may even be cracks), the tile body is not fully calcined, has poor wear resistance, low flexural strength, and higher water absorption. Such vitrified tiles are extremely susceptible to contamination. 4. Assemble: Take out 4 pieces of products of the same specification and model at will and assemble them. Through this step, you can check the size, flatness, and right angles of the tiles. 1) Check the size of the tiles. Take out two pieces of the same type of product and place them on a horizontal surface. Use the tips of both hands to slide back and forth along the edges of the tiles. If there is no obvious lag when passing through the joints of the tiles, It means that the size of the ceramic tiles is relatively good and the error is small. The smaller the size error, the better the paving effect of the ceramic tiles will be! On the contrary, if there is an obvious feeling of sluggishness in the tiles, it means that the size error of the tiles is large, which will affect the effect of paving! As shown in the figure below: 2) Check the flatness of the tiles. Place two or four tiles of the same type on the flat surface according to the same pattern. Slide your hands back and forth on the tile surface. If there are no joints after passing through the tiles, An obvious sense of height indicates that the flatness of the tiles is good. On the contrary, it indicates that the flatness of the tiles is poor, which will affect the overall effect of the tile paving. If the flatness of the floor tiles is poor, in serious cases, people may trip! Therefore, attention should be paid to this point. The method is as shown in the figure below: 3) The problem of the right angle of the ceramic tiles. Nowadays, the ceramic tiles are mainly rectangular. Each corner of the ceramic tiles is a right angle. If the right angles are different, it will also affect the quality of the ceramic tiles. For the paving effect, take four tiles of the same type and splice them together. If the joints of the four tiles cannot be tight and there are always gaps in one or two joints, it means that the right angle of the tiles is not particularly good. As shown below: 5. The test is only aimed at the anti-slip problem of floor tiles. For floor tiles, the materials are mainly divided into two types: vitrified and glazed. As for the anti-slip problem of current ceramic tiles, the common practice now is to apply them on the brick surface. Add water, and then step on it to see if it is slippery. This approach is actually not completely appropriate, because some tiles, especially vitrified tiles, will feel more slippery after adding water. This principle is somewhat similar to that of glass. Add water between them. If you want to open the glass, you will find it difficult because the water squeezes out the air in the middle, making the bricks and shoe uppers in closer contact, so they feel more involved. And some vitrified bricks are more comfortable when no water is added. But it feels slippery. Regarding this, my personal suggestion is to try both adding water and not adding water!
