Puruide 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:
Petrochemical industry-- heat insulation and sound absorption of equipments for petroleum industry, power industry and chemical industry.
Construction industry-- building's exterior wall, partition wall, curtain wall, roof and building envelope thermal insulation and acoustic noise reduction.
Mining industry-- heat preservation and fireproof for industrial kiln, oven, large storage tank and shipping.
