Actually, the professional knowledge of ceramic tiles is not something that you can understand in a few words, because it is designed to a wide range. I personally think that as a shopping guide, the first thing you have to learn is how to distinguish one. The quality of ceramic tiles, if you don't even know how to distinguish the quality of a ceramic tile, how can you convince customers that you are professional! And when you introduce products to customers neutrally and objectively in a specialty store, it is when you are convincing, not like a lower-level salesperson who will only 'sell melonsHow to choose the quality of ceramic tiles:
Currently, there are roughly two styles on the market: antique tiles and polished tiles. It does not matter which tiles to buy, but how to choose them is important. These methods are all used by people in the industry to test tiles. Good or bad method, although it cannot be said that 100% of good bricks can be picked, but at least 80% can't be wrong! Just remember a few points when choosing tiles, the others are not important:
1. Look at the back of the rotating body to see if the color is pure. Generally, the pure color is milky white (white), not black, No yellowing or black spots on the surface, even worse, black hair and yellowing proves that the brick itself has impurities, and the density of the bricks is more certain to decrease when there are more impurities, and it is easy to break and damage in the normal practical process. However, the back of the brick body cannot be very white and it is not normal. It means that too much zirconium silicate raw materials are used. One of the national tests for radioactivity in ceramic tiles is to detect the practical amount of zirconium silicate raw materials, which can make bricks. It turns white and bright, but the zirconium silicate raw material is also one of the main killers of radioactivity, so we must pay attention to it. Generally, regular manufacturers have a national inspection report certificate, you can ask them to show it. Note: it must be a color certificate bound with a photo frame or the parameter at the back of the product brochure indicates that it is not a copy of the inspection report, which is It can be forged.
2. Check whether the particles on the side of the tiles are fine and uniform. If the particles are large and rough, the density of the tiles will be loose, and there will definitely be problems during use. A simple example: when you get the house Generally, it is a rough room, and the wall is made of cement and it is very rough. When you use putty powder, the wall is smooth and delicate. You can use this standard to look at it.
3. Stand up the bricks and hit the bricks with your hands. The clearer the sound proves that the density of the bricks is higher and the quality is better. The duller the sound proves that the density of the tiles is worse, and the stain resistance of the tiles is The durability is worse.
4. If you are buying a polished tile (a floor tile above 600 specifications), touch the front surface of the tile with your hand (touch with the back of your hand). The smoother you get it, the less pinholes on the surface of the tile will be. The higher the pollution capacity, as long as it is not in the bathroom or kitchen, there is no need to worry about non-slip problems.
5. Look at the gloss of the brick surface in the same color. Generally, the floor tiles are placed on the inclined board, and there will be spotlights or fluorescent lights on them. Look at the shadows of these light bulbs on the surface of the brick (just like looking in a mirror). 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 proves. The lower the hardness of the brick. Note: I am referring to polished tiles, and you must compare them with the same color. You can't compare yellow tiles with white tiles. That is wrong.
6. If you are buying antique bricks, touch the front of the brick with your hands, and feel whether the glaze on the brick surface is fine or not. Then use your eyes to look closely to see if the particles of the glaze are rough, etc. . When buying antique tiles, you must pay special attention to the quality of the glaze. If possible, let the salesperson explain the production process of the glaze in detail. Because the glaze is the life of the antique brick, and the color is the soul of the antique brick, there must be more color Contrast experts, to see if the color is pure, choose a product with a purer color, and it's basically OK.
7. If you are buying tiles (wall tiles), look at the side of the brick body between the embryo and the glaze, and look at the thickness of the glaze. If it is too thin, you can’t ask for it, because it will take a long time. There will be breakage or seepage. Look at whether the glaze on the surface of the tile is bright, and the glaze is of good quality.
The above methods 1, 2, and 3 are common to all bricks, and 4, 5, 6, and 7 are methods for different products. Adding a few sentences about the weight of bricks is also a method, the heavier the heavier the higher the density, but this is not useful for all bricks, for example, it seems that Oceano and several other big brands have a kind of 'lightweight brick'. The product is very light but of good quality. Therefore, the weight comparison can only be used for traditional ceramic tile products. If conditions permit, pour a glass of water on the back of the brick body to see the water absorption rate of the brick. The faster the brick is, the worse the brick is, and the slower the brick is, the better. This is the water absorption rate of tiles, which is generally international standard. Below 0.4%, that is, pouring 100 grams of water bricks will only absorb 0.4 grams. The bricks that meet this standard are basically good bricks.
