The selection method of ceramic tile
1. Look at the appearance. The color of ceramic tile should be uniform, surface finish and flatness is better, periphery rule, design is complete, draw four or five pieces from one box to see whether have chromatic aberration, deformation, lack of edge and so on defect.
Listen. With hard objects, the clearer the sound, the higher the degree of porcelain, the better the quality. Can also be a corner left thumb and forefinger and middle finger clip ceramic tile, easily down, with his right hand index finger tapping the tile part, such as voice clear, sweet after taste, such as sound depressing, ZhiZhuo as inferior.
3. Drip test. The water droplet on the back of ceramic tile, see the fast and slow after the water disperses, generally speaking, the slower the water absorption, the higher the density of the tile; On the contrary, the faster the absorption, the less dense the density, and the inner quality of the former.
Four feet. The accuracy of ceramic tile edge length is higher, the effect of shop post is better, buy high quality ceramic tile not only easy construction, and can save working hours and auxiliary material. Measuring the size of each tile with a tape measure is different, the accuracy is high.
In addition, to observe its hardness, ceramic tile is good, toughness, not fragile as a product. To ceramic tile pieces scratch each other edges and corners, see broken fragments breakup is close or loose, is hard, brittle or softer, is leave scratches, the powder scattered or if the former is the top grade, the latter is bad.
