Main causes of cracks in rock wool board and their solutions
Clicks: 【1170】 Date: [2014/7/20 16:46:49]

There are several reasons for cracks in the protective layer and finish of the cotton board:

1. The bonding strength between the protective layer and the thermal insulation layer is low or empty;


2. Due to the concentration of stress at the door and window openings, the protective layer and the facing layer are vulnerable.


3. The protective layer and the decorative layer have a large shrinkage and deformation, which leads to the birth of vitality flaws;

In view of the main causes of cracks in the rock wool board mentioned above, the following crack prevention measures should be adopted:

1. Use micro-tightening anti-crack mortar or polymer mortar with high adhesive strength, small shrinkage and deformation, and not necessarily elasticity. Because the texture of rock wool board is soft, the thickness of anti-crack mortar is preferably 25-30.


2. Use steel mesh or steel mesh sandwich Shijiazhuang rock wool board reinforcement layer. On the one hand, the steel mesh or reinforced structural layer is adjacent to the insulation layer and the protection layer; on the other hand, the shrinkage stress and Stress is concentrated so that the goal of reducing and avoiding gaps is reached. In the part where the wall is easy to make gaps, it is necessary to take part of the step of setting the reinforcing net.


3. Develop the protective layer into seams and waterproof the caulking to reduce shrinkage and temperature stress.
