In spring, the trees sprout new shoots. The green leaves cover the entire trunk. When it was autumn, the leaves began to turn yellow and fall into the soil. The renovated good house, with the passage of time, will inevitably have problems due to aging. In particular, ceramic tiles are prone to emptying and falling. Xiao Bian and everyone to analyze the reasons for the next easy to fall off the tile and how to repair.
| The number of tiles falling causes |
Grassroots problem: The ground floor is not clean, the moisture is not enough, the dust on the back of the tile is not removed, too much water before the tile will cause the tile and the wall to stick tightly. After a period of use, it will loosen. Falling situation.
Tile quality problems: The quality of the tiles is also one of the factors that affect the looseness. The water absorption of the tiles directly affects the firmness of the paste. According to the national regulations, the water absorption of porcelain tiles is E≤0.5%, and the shrinkage expansion rate of porcelain tiles is about 4×10-6. When the tile water absorption rate or the cement does not meet the standard, after the thermal expansion and contraction, the ceramic tile and cement Inconsistent shrinkage leads to separation.
Construction process problems: if the cement mortar of the cushion layer is too thick or the cement adds too much water during the construction process, tiles of the paved tiles will fall off; in addition, if it is a large-size tile, if the joints are too small, the thermal expansion and contraction After shrinking and squeezing each other, it can easily cause warping and cracking.
Daily use problems: The water absorption rate of the inner tiles is low. If the tiles are not completely cemented to the tiles, they will be subject to greater impact, such as trampling or impact by hard objects, which will easily cause the separation of tiles and cement. Empty drums.
