How to choose a tile test method?
The simplest is to pour the cup of water and then buckle the tiles to see how his water there is no printed and then is the sound of the sound of boring stuffing brick on the poor quality of the sound of crisp sweet is good brick is the density density is greater the more solid
1 with a glass of water poured on the back of the tiles, water stains spread quickly, indicating high water absorption, otherwise the lower
2. You can use a hard object to scratch the tile glazed, if left traces, indicating poor quality
3. Look at the color of the tiles is not clear, with the naked eye to see if there is no pinhole, pinhole easy to accumulate dirt
4. Tile flatness, flat side, easy to shop, the effect is also good (visual method, the tiles placed on the flat surface to see whether the four sides are fully consistent with the flat surface, while looking at whether the four corners of the tiles are right angle , And then placed in the same variety of tiles and the same type of tiles to observe the degree of color difference)
5. Select the floor tiles often see the material on the ground hard to step on the ground, which can only show that the bottom of his tiles and can not explain the quality of his tile
6. In the ground draw, poor tiles due to the density of the relationship, completely like a chalk, draw all where the mark.
7. focus on a "look". A look level. Excellent products, third-class goods and other goods are worrying; two look appearance and glazed. Good tiles without convex concave, drums, Qiaojiao and other issues, side straight face flat. Glazed smooth, no particles or color shades of different phenomena; three look at the pattern. Pattern to be delicate, no obvious color, dislocation, broken or different shades.
8. Focus on "listening". To one hand the thumb, index finger and middle finger folder tile corner, easy to hang, the other hand index finger tapping the lower part of the tile, such as the sound clear, sweet for the top grade, such as the sound boring, astringent turbidity for the defective.
9. cut out the tile pieces (usually to the store to be broken debris observation), see the fracture at the Department. Broken at the fine, hard and brittle, consistent color for the top grade.
10. The water droplets on the back of the tiles, the water spread after the slow growth of the ceramic tile density, as the top grade
