In recent years, bathroom partition is very popular. With the continuous development of economy, people pay more and more attention to environmental sanitation. More public toilets also began to install partition equipment. It not only protects people's privacy, but also saves space. However, it is also said that cracks will appear when the partition is used for a period of time. Do you know what causes them? Jinan toilet partition manufacturers will show you the three major causes of cracks.
Jinan toilet partition
1. Causes of cracks:
(1) Pretreatment structure, mortar formula and laying method can also cause cracks. The wall flatness error is large, and the bricklaying ash is not removed. The hardware manufacturer suggests to use coarse mortar directly. Too much ash makes cement mortar solidify, shrink and crack. In addition, tile workers hit too many bricks when laying tiles, resulting in tile cracking.
It was not seen at that time, but it was found after the shrinkage of cement mortar. Just as a batch of bricks are laid by different workers in different rooms, the tiles in one room are in good condition, and the cracks in the other room may be related to the mortar ratio and laying method.
(2) Due to the imperfection of the scheme and the improper construction sequence, the pipeline needs to pass through the wall after ash removal, while the sanitary partition will produce irregular cracks due to strong impact and vibration during use, which needs normal operation.
(3) Material quality
If the anti cracking performance of toilet partition does not meet the standard requirements, it will crack due to the influence of internal stress after pasting in humid environment for a period of time. The distribution of cracks caused by these reasons is relatively uniform, and there is no certain law. When the same or similar conditions are used in different areas, the probability of cracks is the same. Jinan toilet partition manufacturers suggest that consumers in the purchase should pay attention to this content.
2. Treatment of partition cracks in Jinan toilet
(1) Catch the white. After the joints are finished, the interior and exterior walls are painted and whitewashed. Powder for whitening must be mixed with water before use. Therefore, as long as the paint is applied, the water vapor will invade the joint after the tape falls off. For the mortar which is not completely dry between the joints, only frost is added, and there is no cohesive force at all.
(2) Put on the tape. After the joint is filled with mortar, the adhesive tape is pasted at the joint to strengthen the bonding between the board and the board. But the waterproof performance of this layer of glue is very poor, and even has no waterproof function at all. Therefore, in the third step, the tape basically falls off.
(3) Fill the joint with mortar. There is no problem in the traditional brick bonding mortar, because the brick area is small and the joint is small. Moreover, the way bricks are built is bound to float most of the pressure up and down. The light partition board is more than 2.4m high. Therefore, the bond strength of mortar can not bear the joint tension of 2.4 meters, so the bond strength of mortar can be ignored.
The above is the reason and solution of Jinan toilet partition cracks sorted out by toilet partition manufacturers today. I hope you will understand it better after reading it. I hope these contents can help you.
