I have been in the tile industry for 4 years, so you must plan your own decoration cost before decorating, and carefully plan the use cost of each piece, because the decoration involves more than just tiles, so it is best to record every cost in advance with paper and pen, so that you won't be influenced by sales staff and exceed the decoration budget. First of all, you have to decide what style of tiles you want to buy. At present, there are roughly two styles on the market: antique tiles and polished tiles. What matters is not what tiles you buy. What matters is how to choose and teach you some of the most practical ways to choose tiles, so that you don't have to be fooled by sellers when you buy tiles. These methods are all methods used by people in the industry to test the quality of tiles. Although you can't say that you can choose 1% good tiles, at least 8% of them can't be wrong. I hope to help you. Just remember a few points when choosing ceramic tiles, and the others are not important:
1. Look at the back of the swivel to see if the color is pure. Generally, the pure color is displayed as milky white (off-white), and it is not allowed to be black or yellow, and there are black spots on the surface. Black and yellow proves that the brick itself has impurities, and the density of the brick is more certain to decrease with more impurities, which is prone to fracture and damage in the ordinary practical process. However, it's not normal that the back of the brick can't be very white, which shows that zirconium silicate raw materials are used too much. One of the national tests for radioactivity of ceramic tiles is the practical amount of zirconium silicate raw materials. Zirconium silicate raw materials can make bricks white and bright, but zirconium silicate raw materials are also one of the main killers of radioactivity, so we must pay attention to it. Generally, regular manufacturers have national inspection report certificates. You just need to ask them to show them. Note: it must be the color certificate bound with a photo frame or the parameters at the back of the product brochure indicate that it is not a copied inspection report, and that thing can be forged.
2. See if the granules on the side of the ceramic tile are fine and even. If the granules are large and rough, the density of the brick will be crisp and loose, and there will definitely be problems in the use process. For a simple example, when you get the house, it is usually a embryonic house, and the wall surface is very rough with cement. When you use putty powder, the wall surface will be smoother and more delicate, so you can use this standard to look at it.
3. Stand up the brick and knock it with your hands. The crisper the sound, the better the quality of the brick. The duller the sound, the worse the density of the tile, and the worse the anti-pollution and durability of the tile.
4. If you buy polished tiles (large floor tiles with sizes over 6), touch the front surface of the tiles with your hands (touch with the back of your hand). The smoother you feel at first, the less pinholes there are on the surface of the tiles, the higher the anti-pollution ability. As long as you don't use them in the bathroom or kitchen, you don't have to worry about anti-skid problems.
5. Look at the gloss of the brick surface in the same color. Generally, large floor tiles are placed on sloping boards, and there will be spotlights or fluorescent lamps on them. You should look at the shadows of these bulbs on the brick surface (just like looking in a mirror). The clearer the shadows, the higher the gloss of the bricks, the stronger the hardness of the bricks and the higher the durability. On the contrary, the more blurred the shadows of the bulbs, the lower the hardness of the bricks. Note: I mean polished tiles here, and it must be the same color when comparing again. You can't compare yellow bricks with white bricks, which is wrong.
6. If you buy antique bricks, you should also touch the front of the brick body with your hands to feel whether the glaze on the brick surface is fine or not, and then look closely with your eyes to see whether the particles of the glaze are rough or not. When buying antique bricks, we must pay special attention to the quality of the glaze. If possible, let the sales staff explain the production process of the glaze in detail, because the glaze is the life of antique bricks, and the color is the soul of antique bricks, so we must compare the colors to see if the color is pure, and it is basically OK to choose a product with pure color.
7. If you buy ceramic tiles (wall tiles), you should look at the gap between the blank and the glaze on the side of the tile and the thickness of the glaze. If it is too thin, you can't take it, because it will break or leak after a long time. Look at whether the glaze on the surface of the ceramic tile is bright, and the glaze is bright and 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. Finally, it is also a way to add a few words about the weight of bricks. The heavier the bricks, the higher the density, but this is not useful for all bricks. For example, it seems that Oseno and several other big brands have produced a product called "lightweight bricks", which is light in weight but good in quality. Therefore, the comparison of weight can only be used for traditional ceramic tile products. If conditions permit, take a glass of water and pour it on the back of the brick to see the water absorption rate of the brick. The sooner it proves that the brick is worse, the slower it proves that the brick is better. This is what is usually called the water absorption rate of the tile. The general international standard is below .4%, that is, pouring 1 grams of water will only absorb .4 grams, and the bricks that meet this standard are basically good bricks. Special reminder: don't trust the salesperson to stand up the brick and fall straight. It's loud but the brick is fine. Shit ~ ~ ~ That's right. . . . . Forget it, anyone who knows something about physics knows it. . . . . If you stop talking, you will be scolded by your peers, hehe ~ ~ ~
