Problems solved by technology

The building energy-saving and thermal insulation materials currently used in my country mainly include inorganic and organic. Among them, inorganic thermal insulation materials have a large thermal conductivity and poor thermal insulation effect, but they are fire-resistant and flame-retardant, have a small deformation coefficient, are anti-aging, and have a long service life; organic thermal insulation materials The thermal conductivity of the material is small and the thermal insulation effect is good, but it is easy to burn. Once a fire occurs, the flame spread will be accelerated, and a large amount of toxic gas will be discharged, causing secondary hazards. Moreover, organic thermal insulation materials are not resistant to aging, have a large deformation coefficient, and are stable and poor security
