Problems solved by technology

[0002] Existing A-level insulation materials such as rock wool insulation boards are not environmentally friendly, have poor weather resistance, are difficult to construct, and are easy to absorb water and fall off. The high thermal conductivity of foamed cement insulation boards makes it difficult to adapt to some buildings that require high energy conservation in the country. Chlorine oxygen is often used for homogeneous boards. Magnesium cement, that is, the production of ordinary EPS, has the disadvantage of being easily deformed by anti-halogen and anti-alkali, and has many defects. Foam glass and foam ceramics are also materials with high thermal conductivity. Class B materials such as molded EPS (EPS extruded board, phenolic board, etc.) are all organic materials. Although the thermal insulation effect is superior, they cannot achieve the proper fire resistance, and are prone to fire, posing serious safety hazards.
