——Rock wool is an artificial light silicate discontinuous flocculent fiber material with a soft texture, a density of 150kg/m3, and a thermal conductivity of about 0.07W/(m·K). Its chemical stability is good, acid and alkali resistance. Although the fiber of rock wool is fine, it is neither brittle nor powdery, and has good elasticity.

——In building thermal insulation projects, the light weight and fiber properties of rock wool are mainly used to obtain heat insulation, sound insulation and crack resistance.
