Rook wool products are manufactured with basalt as main ingredient made into inorganic fiber

1. Materials

Rook wool products are manufactured with basalt as main ingredient, made into inorganic fiber in high speed centrifugal machine after melting A certain amount of cementing agent, rustproof oil, silicon oil is added into the raw material which is made into rock wool board

 

2. Application

1. Petrochemical industry -- heat insulation and sound absorption of equipments for petroleum industry, power industry and chemical industry. 
2. Construction industry -- heat insulation and sound absorption of partition, curtain wall, roofs and fences for construction. 
3. Mining industry -- heat preservation and fireproof for industrial kiln, oven, large-caliber storage tank and shipping.
