Benzene board machinery promotes new routes for modern development

The initial insulation materials are mainly organic materials such as polystyrene board machinery, but organic materials naturally suffer from the defect of poor fire resistance. The styrene board machinery has promoted the new route of modern development. Today's technology is continuously upgraded. The current polystyrene board machinery has the fire protection effect of B2 and B1 levels, and more fireproof and waterproof insulation materials have been introduced. Paying more attention to moisture and water resistance is an important development direction for thermal insulation materials. The water absorption rate of the material is an important factor that should be considered when selecting insulation materials. The thermal conductivity of water at room temperature is 23.1 times that of air. The use of new nanotechnology insulation materials is also a major research direction. At present, several new thermal insulation materials have emerged (such as nanoporous thermal insulation materials, composite thermal insulation materials asbestos substitutes, etc.). Nanoporous thermal insulation materials: With the continuous development of nanotechnology, nanomaterials are becoming more and more popular. Nanoporous siliceous thermal insulation material is a new application of nanotechnology in the field of thermal insulation materials, and most of the pore sizes in the constituent materials should be at the nanometer scale. According to the theory of molecular motion and collision, the heat transfer of gas is mainly through the higher-velocity molecules on the high-temperature side, colliding with the lower-velocity molecules on the low-temperature side to transfer energy.
