Rock wool board

Fire prevention board

The fire-proof rock wool board of Fulong is a kind of inorganic fiber which is made of basalt and other natural rocks by high temperature melting and centrifugal blowing. The main raw materials for rock wool production, including acid rocks such as basalt, diabase, gabbro, granite, diorite, quartzite, andesite and a small amount of alkaline solvents such as limestone and dolomite, are common non-metallic materials in China, with wide distribution, large reserves, easy mining, and good basic conditions for rock wool production in China.
Advantages of fireproof rock wool board:
⊙ it has the highest fire protection level A1, which can effectively prevent the fire spreading.
⊙ the size is very stable and will not stretch, shrink or deform in the fire.
⊙ high temperature resistance, melting point higher than 1000 ℃.
⊙ no smoke or combustion droplets / debris will be generated in the fire.
⊙ substances and gases harmful to the environment will not be released in the fire

Use of fireproof rock wool board:
Rock wool insulation board is widely used in shipbuilding, metallurgy, power, construction and other industries. The construction and installation are convenient, the energy-saving effect is remarkable, and the performance price ratio is very high.
Hydrophobic additives are added to the marine and hydrophobic insulation board in production, which has good moisture-proof performance.
Marine thermal insulation board: used for thermal insulation and fire partition of ships;
Hydrophobic insulation board: it is used in vehicles, mobile equipment, cold storage engineering, air conditioning pipeline, as well as the application occasions with certain requirements for moisture-proof and fire insulation in humid environment.
Rock wool board for building has excellent performance of fire prevention, heat preservation and sound absorption. It is mainly used for heat preservation and sound insulation of building walls and roofs, fire prevention and noise reduction of building partitions, firewalls, fire doors and elevator shafts.
