China [CN] rockwool insulation is a product with certain strength. The product is mainly used for fireproofing and sound absorption of partition walls and curtain walls, thermal insulation of roofs, retaining structures and geothermal systems as well as thermal insulation and fireproofing of industrial kilns, ovens, large sized tanks and vessels, etc.
Rock Wool Board :
IKING 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.
Application of rock wool:
Petrochemical industry -- heat insulation and sound absorption of equipments for petroleum industry, power industry and chemical industry.Construction industry -- heat insulation and sound absorption of partition, curtain wall, roofs and fences for construction.Mining industry -- heat preservation and fireproof for industrial kiln, oven, large-caliber storage tank and shipping.
