How to choose thermal insulation mesh?
First, first observe the appearance. High-quality products have a more beautiful appearance. The main thing to look at is whether the specifications of the holes are neat and uniform. Due to the production process, the holes are not very uniform and neat, but they are generally uniform.
Second, check the feel and quality. The higher the quality of the product, the better it feels. It feels smooth and does not sting. If the product is not very soft, its hardness is generally higher. Then check the relevant quality, weight, and product inspection reports.
Criteria for the "anti-cracking" mechanism of exterior wall insulation mesh cloth exterior wall insulation
This anti-cracking idea requires that the deformation of the material is not free. The material will be affected by external restraint stress and will be completely restrained, that is, it is in a fully restrained state. Taking the space problem as an example, the following relationship exists:
txy=tyz=tzx=0
In this case, the material has a maximum binding stress, which has nothing to do with the length, as long as the strength of the material can exceed the maximum binding stress: R≥max
Perhaps the ultimate stretch of the material is greater than the maximum constrained tensile deformation Ep≥max
That is to say, as long as the selected material has sufficient tensile strength and ultimate stretch, cracking will not occur. This description criterion is called the "resistance" criterion for controlling cracks.
