     Application of aluminum silicate fiber bulk and rock wool 

     1. Aluminum silicate fiber bulk 

Aluminum silicate fiber bulk is used as high temperature insulation material in various industrial furnaces and ladles, casting drums and immersion nozzles. It is also used as electrical and heat insulation materials for industrial electric furnaces, sealing material for furnace door and furnace expansion joint, lining of aluminum mold, mold release of glass-ceramics and hot-melt glass, high temperature gasket, thermal and electrical insulation materials for heating devices, sound and heat insulation material of automobile muffler, insulation material of exhaust pipes, etc.

     2. Rock wool

     Rock wool is widely used in shipping, metallurgy, electric power, construction and other industries. It  has good thermal insulation and sound insulation performance. Its construction and installation are convenient, and energy saving effect is remarkable. It has a high performance-price ratio. Marine and water-repellent rock wool insulation boards are produced with water-repellent additives and have good moisture resistance. Marine rock wool board is used for thermal insulation and fire barrier of ships. Water repellent rock wool board is used for vehicles, mobile equipment, cold storage projects, air conditioning pipes, and thermal insulation and fire protection in humid environments and applications that have certain requirements for moisture resistance. Rock wool board for construction has excellent fireproof, thermal insulation and sound absorption properties. It is mainly used for thermal insulation and sound insulation of building walls and roofs; fire protection and noise reduction of building partitions, firewalls, fire doors and elevator shafts.
