The PVC Corner Protectors plays a very large structural role in the insulation system during construction. It is mainly to prevent the occurrence of cracks. The Pvc Drywall trim will not be easily damaged when it is hit, unless it is a serious matter. However, the Pvc Drywall trim is not only impact-resistant but also easy to construct. Next, let's take a look at how to construct the corner bead round to prevent the aging of the insulation layer!
Although the bull nose drywall polyurethane rigid foam insulation layer itself has good anti-aging ability, it will also accelerate the aging of polyurethane foam materials in harsh environments such as long-term sudden cooling and heating. Therefore, improving the environment of the polyurethane rigid foam insulation layer material, such as reducing ultraviolet radiation, reducing water vapor, chemical erosion, moderate temperature and humidity, avoiding long-term sudden cooling and heating or long-term exposure to cold and hot environments, slowing down its aging and extending its service life, bull nose drywall is also very necessary for exterior wall insulation.
The glue powder polystyrene particle insulation slurry contains a large amount of inorganic materials, and its aging performance is superior to that of polyurethane rigid foam organic materials. Using ZL glue powder polystyrene particle insulation slurry, a 1.5~2.0cm thick leveling treatment is made on the surface of the polyurethane rigid foam insulation layer, which has the following protective and anti-aging effects on the polyurethane insulation layer: a. The 1.5~2.0cm thick glue powder polystyrene particle leveling layer, coupled with the aging resistance of the anti-cracking layer and corner bead round finishing layer materials, can effectively prevent ultraviolet rays from damaging the insulation layer.
