Rock wool board is made of select fine basalt as the major materials which is pulled into 4-7µ non-continuous fibers after melted by adopting advanced international four-roller centrifugal cotton-making procedures and adding a certain of adhesives, dust laying oil and water repellent into rock wool fibers. It can be made into products series with different density according to various uses through the technology of sedimentation, solidify, cutting and etc.
1. Superior Fire Resistance
2. Good Water reprellence
3. Environment Friendly
4. Stable Insulation Performance
5. Excellent Acoustics
6. No Corrosion On Insulation Body
Application of rock wool:
Rock wool was used for building materials, and steel structure insulation
soundproof and fireproof used for wall and roof of house
Heat preservation for steel structure building
Heat Insulation for wall and roof of house to save energy
For indoor partition wall, Train compartment.
Rock wool board for ship thermal insulation and fire prevention partition keel interlayer sound insulation; Rock wool for building has excellent fire prevention, heat preservation and sound absorption performance. It is mainly used for building wall, roof insulation; Fire prevention and noise reduction of building partitions, firewalls, fire doors and elevator shafts.
