Problems solved by technology

[0002] In recent years, fires in building external insulation materials have caused serious casualties and property losses. Building flammable and combustible external organic thermal insulation materials have become a new type of fire hazard. Relevant national departments have issued documents to limit the use of flammable and combustible thermal insulation materials.
Although inorganic thermal insulation materials have many advantages such as high strength and fire prevention, their thermal insulation effect is far inferior to that of organic materials, and their construction techniques and methods are not as mature and convenient as organic materials.
[0003] Most of the A-grade materials on the market now have disadvantages such as poor thermal insulation performance, unstable products, and short supply.
