What causes cracking of frp plastic panels during use?
FRP plastic panels are widely used in the construction field because of their unique characteristics, but the environmental pollution is getting more and more serious. Therefore, high-strength frp plastic panels have received special attention from people and are more and more widely used in the construction industry. Sometimes, frp plastic Panels will crack during use. What causes this? How to improve? Below, Tangshan Runfeng composite material Co.,ltd will introduce to you:
1. FRP plastic panels sometimes crack at corners or steel structures. The reason may be that during use, FRP plastic panels are brittle because of their brittleness, but on the contrary, their toughness is lower, and their tensile and bending resistance are lower. difference. If high-strength frp plastic panels are stretched or bent, they will crack. The way to improve is to take protective measures during transportation to avoid bumps on the road, and to avoid high-strength drawing and bending of anticorrosive lighting tiles during construction.
2. As the hardness of frp plastic panels is relatively large, this will cause frp plastic panels to crack after being used for a period of time, and the durability is slightly worse. The improvement method is that during construction, a non-slip thick wooden board must be placed on the horizontal position of the frp plastic panels, and the foot should be stepped on to carry out the guide holes and fixing screws of the lighting tile. It is strictly forbidden to step directly on the wave crest or frp plastic panels. , So as to avoid deformation or cracking of frp plastic panels.
3. FRP plastic panels have strong water absorption, which will cause the frp plastic panels to become swollen after being damp, resulting in deformation and cracking of the frp plastic panels. The method suggested by Runfeng is that the frp plastic panels must be fixed with waterproof gaskets. The gap between the frp plastic panels and the frp plastic panels needs to be pasted with a water-stop tape. There must be at least a certain amount of overlap during the vertical lap. And attach two waterstops. This can effectively prevent water or dust from entering the plant, and at the same time prevent cracking of frp plastic panels caused by water absorption.
