The tensile strength of the Profile Pvc must meet the standard

At present, the weight of Profile Pvc used in the external wall insulation system in the market in my country is about 130g 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 Wall Corner 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 tensile strength, but also the crack-resistant 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 Wall Corner itself meets the standard.
The use of Profile Pvc 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 wider cracks that may have been generated into many finer cracks, thereby forming its crack resistance.
The surface coating material and coating amount are of great significance to the alkali resistance of the Wall Corner, and the Glass Fiber variety is of decisive significance to the long-term alkali resistance.
