Reinforced Profile Pvc material for external wall insulation surface

The Profile Pvc is a reinforcing material for the external wall insulation surface. Its main functions are: improving the mechanical strength of the surface, ensuring the resistance continuity of the finishing layer, dispersing the shrinkage pressure and insulation stress of the surface, avoiding stress concentration, and resisting the cracking of the surface caused by natural temperature and humidity changes and accidental impact. Therefore, the Profile Pvc plays an important role in the external insulation system, so the selection of good Wall Corner is also an important part of ensuring the comprehensive quality of the external insulation system.

At present, the weight of Profile Pvc used for external wall insulation system in the Chinese market is about 130 grams per square meter, and the strength is generally low. Its normal fracture strength is only 1000N/5cm, or even lower.
For this reason: the technical indicators of Profile Pvc for external wall insulation projects require standardization, and the purchased Profile Pvc must be qualified before use. When controlling cracks in external wall insulation, not only the insulation layer material is required to have a certain tensile strength and ultimate stretch, but also the anti-cracking protective layer material is required to have sufficient tensile strength. For this reason, when selecting Profile Pvc, it is necessary to pay attention to whether the tensile strength of the Profile Pvc itself meets the standard.
The use of Wall Corner compounded in the plastering mortar can effectively increase the tensile strength of the protective layer on the one hand, and on the other hand, because it can effectively disperse stress, it can disperse the wide cracks that may have been generated into many fine cracks, thereby forming its anti-cracking effect. The surface coating material and coating amount are of great significance to the alkali resistance of the Wall Corner, and the type of Glass Fiber is of decisive significance to the long-term alkali resistance.
