The Rock wool products regard basalt as its main raw materials, after the towering stove is melted, make basalt high-temperature melting body into inorganic fiber with high-speed acentric equipment, put bond, polish, silicone oil in at the mean time. According to different requirements, we can manufacture many kinds of products such as rock wool platerock wool tuberock wool blanket. It is widely used in varies of high-temperature pipetank and equipment insulation of the domain of oilchemicalmetal and so on .Also can be used in thermal insulation of boats and the insulation and sound absorption of the buildings wall and ceiling.
