Building Insulation Material Rock Wool ??
?
?
1.Main components:
?
Rock wool uses basalt and other natural ore, as the main raw materials. It fused into a fibrous after the high temperature, added suitable amount of binder, then made by curing processing.
?
2.Advantage:
?
1. Quality lighter
?
2. Low thermal conductivity
?
3. Heat insulation
?
4.Good workability
?
5. Excellent tensile strength
?
6.Good corrosion resistance and can be use for c
7.Excellent sound-absorbing performance
?
8. Good seismic performance
?
3.Application:
?
1. Petroleum, metallurgy, electric power, machinery, chemical industry equipment insulation, for sound-absorbing noise reduction
?
2. Building partition wall, curtain wall, fire doors, elevator well, roof and retaining heat insulation, for sound-absorbing noise reduction,
?
3. Industrial furnace heat insulation, oven, large diameter storage tank and heat preservation of the ship, for fire protection.
?
4.Specification:
