To improve the durability and stability of EPS wall panels under extreme high temperature conditions exceeding 100°C, the following methods can be adopted:
Increase molding density: According to Nanjing Shengnuoda New Materials Co., Ltd., as the molding density of EPS foam increases, its thermal stability will also increase accordingly. Although the maximum allowable operating temperature has not changed, its performance under high temperature conditions can be improved to a certain extent by increasing the density.
Adding flame retardants: According to research on thermal decomposition kinetics analysis and life prediction of expanded polystyrene, adding flame retardants can effectively improve the thermal stability of EPS. This improvement can be explained from chemical and physical processes, helping to improve the stability and durability of EPS wall panels under high temperature conditions.
Leveraging Nanotechnology: A study of electrospun expanded polystyrene (EPS)/reduced graphene oxide (RGO) nanofiber composites showed that thermal stability, Young's stability, and thermal stability were observed in all nanocomposites compared to pure EPS. Significant improvement in modulus and tensile strength. This shows that through the application of nanotechnology, the high temperature resistance of EPS wall panels can be significantly improved.
Adopting special construction technology: The technological innovation of EPS modules includes fully automatic computer-controlled integrated production and one-time high-temperature vacuum forming. These processes ensure the stability of product quality and the accuracy of geometric dimensions. In addition, the unique cast-in-place concrete system solves the problems of hollowing, cracking, and falling off of the building's external insulation layer, helping to improve the overall stability and durability of the EPS wall panels.
Use of moisture-permeable waterproof materials and high-performance resins: When using the EPS wet external thermal insulation method for the walls of wooden houses, thin-coating treatment is carried out using moisture-permeable waterproof materials and resin materials with excellent durability, weather resistance, and deformation recovery properties. This method not only improves the durability and stability of EPS wall panels, but also maintains good craftsmanship.
By increasing the molding density, adding flame retardants, utilizing nanotechnology, adopting special construction techniques, and using moisture-permeable waterproof materials and high-performance resins, the durability of EPS wall panels can be effectively improved under extreme high temperature conditions exceeding 100°C. and stability.
