Lightweight partition wall is a new energy-saving wall material easy to install and environmental protection, there are a lot of manufacturers, but some products appear cracks so what is the reason?

1. In the production process, the quality control of plate raw materials is not strict. Some small factories do not have laboratories and other testing measures, so they can only judge whether the products are qualified by experience

2. Some plate production enterprises do not reach the national standard production process is not appropriate, resulting in excessive water absorption of the product drying shrinkage value exceeds the standard

3. In the production process, the maintenance measures are not in place so that the board hydration is not complete

4. The plates shall be sent to the construction site to be put on the wall if they are not old enough

5. In order to make it convenient to brush the release agent on the side of the plate mold in the production process, in order to reduce the cost, the release agent often USES waste oil, which seriously weakens the bonding effect between the plate and the mortar with joint.
