Nowadays, when it comes to important materials in the construction industry, colored steel plates are one of the indispensable materials, which are often used in construction. However, many users soon discover that the color steel plate cracks during use. Why is this? Below, Jinan Color Steel Plate Factory will analyze for you:
佰富彩1. The bonding compressive strength between the protective layer and the insulation layer is low, or the wall is hollowed out with rock wool colored steel plates.
佰富彩Preventive measures: The color steel plate will layer the development trend of the protective layer, leave gaps, and do a good job of sealing and moisture-proof, in order to reduce shortening and temperature stress.
2. Due to the convergence of ground stress at the edges of doors and windows, there are systematic loopholes in the protective layer and decorative layer.
Preventive measures: Use micro anti rust cement mortar or closed cement mortar with high bonding compressive strength, small shortening deformation, and certain ductility. Due to the material being too soft, the thickness of anti rust cement mortar is 25-30.
3. The protective layer and decorative layer are greatly shortened and deformed, leading to loopholes in the system that creates diseases.
Preventive measures: Using steel wire mesh or steel wire mesh sandwich chocolate colored steel plate for high-rise building may improve the proximity between the physical layer and the insulation layer and protective layer, and may also shorten the ground stress and the discrete variable stress between the protective layer and the decorative layer, thereby achieving the overall goal of reducing and avoiding gaps.
These three reasons that cause cracks in color steel plates are all important for everyone to understand in order to take more precautions in future applications and avoid the occurrence of cracks. Thank you for your attention http://0082tv.com .
