Product Introduction
Rock wool board is the use of high-quality feldspar, dolomite, basalt and other natural rocks as the main raw materials, high-temperature melting and processing of inorganic fibers, with a light weight, small thermal conductivity, heat absorption, non-combustible features is a new type of thermal insulation, fire insulation, acoustic materials, should have a fire prevention, thermal insulation, sound insulation, thermal insulation and other functions.
Feature:
- It has A1 fireproof grade, effective flame retardant.
- Low thermal conductivity, with excellent thermal insulation effect.
- internal fiber structure effectively reduces the impact of noise.
- Chemically stable and non-corrosive.
- does not contain harmful substances, does not produce mold and bacteria.
Application:
- petroleum, chemical, metallurgy, electric power, textile and other industrial boilers and equipment pipeline insulation
- Insulation and sound absorption of partition wall, ceiling and internal and external walls in the construction industry.
- Fire prevention and noise reduction of partition walls, fire walls, fire doors and elevator shafts.
- the plane and curvature radius of the larger tanks, boilers, large steel structures, glass curtain walls, thermal insulation and fire insulation of the ship’s thermal insulation and fire partition.
