Precautions for buying ceramic tiles


Precautions for buying ceramic tiles

1. Look at the back of the rotation to see if the color is pure. Generally, the pure color is milky white (white), not black, not yellow, and black spots on the surface Even worse, the black hair and yellow color prove that there are impurities in the brick body itself, and the density of the brick will decrease more surely when there are more impurities, and it is prone to breakage and damage in the normal practical process.

But the back of the brick body cannot be very white and it is not normal, indicating that too much zirconium silicate is used as raw material, and one of the national inspections of ceramic tiles for radioactivity is to detect silicon The practical amount of zirconium acid raw materials, zirconium silicate raw materials can make bricks white and bright, but zirconium silicate raw materials are also one of the main murderers of radioactivity, 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.

Second, 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, for example, a simple Example: When you get the house, it is usually a rough room. The wall is made of cement and the surface is very rough. When you use putty powder, the wall is smooth and delicate. You can use this standard to see it. .

3. Stand the bricks up 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 dull the sound proves that the density of the tiles is higher. Poor, the poorer the anti-fouling and durability of ceramic tiles.

Four. If you are buying polished tiles (terrain tiles above 600 specifications), touch the front surface of the brick body with your hand (touch with the back of your hand), and the smoother the brick surface will be The fewer pinholes, the higher the anti-fouling ability, as long as it is not in the bathroom or kitchen, there is no need to worry about non-slip problems. Precautions for buying ceramic tiles 5. Look at the glossiness of the brick surface with the same color. Generally, the floor tiles are placed on the inclined board, and there will be spotlights or fluorescent lights on them.
