Problems solved by technology

[0002] Lightweight partition board is a new type of energy-saving wall material. It has the advantages of light weight, high strength, multiple environmental protection, thermal insulation, sound insulation, breathing and humidity control, rapid construction, and reduced wall cost. Therefore, it is widely used in the field of architectural interior decoration. It is very popular, but the lightweight partition boards currently used in the market have poor fire and heat resistance, and fires are likely to cause safety problems
