>>> Links: Prone to Problems with Tiles
1. The ground floor is not treated properly, or the watering is insufficient;
2. The cushion cement mortar is too thick or water is added;
3, the dust on the back of the tile is not removed or water infiltration is not enough, when the tile is not cleaned on the back of the tile stains, water traces too much, resulting in false bonding;
4, for the national standards of porcelain tiles water absorption is E ≤ 0.5%, national standards for ceramic tiles is ≤ 10%, so the adhesive force is far weaker than the ceramic brick, the expansion rate of the ceramic tile is about 4 × 10 -6, the shrinkage rate of concrete is more than double that of porcelain bricks. When the cement shrinks, the shrinkage of porcelain bricks and the ground is inconsistent, and two different objects must be separated. In this case, the bottom of the porcelain bricks is clean. status;
5. Porcelain tiles have low water absorption rate, such as large impact force (such as slamming, etc.) when they are not completely cemented to the cement, resulting in the separation of two different bricks and cement and a clean brick bottom.
6. Due to the inconsistent density of the mortar, the mortar has settled after the completion of the initial condensing period, resulting in hollowing and loosening;
7, cement does not meet the requirements;
8, and the thermal expansion coefficient of cement is different, there is a temperature difference stress after large-size tiles are paved, seasonal temperature fluctuation will cause the bond strength to decrease;
9. The product itself has an unreasonable back grain pattern or a very large amount of brick base powder and has not taken corresponding measures during construction.
