Exterior Wall Heat resistant soundproof thermal Insulation Rockwool fireproof insulation Board for air and duckd
Rock wool is made from natural rock such as basalt, diabase, and dolomite. The natural rock is melted into melts in the cupola at a very high temperature of about 1500°C. And the melts lava is then pouring to high-speed spinners through which the melts get into fibers. The just fiberized fibers are collected together to form the original wool mat through negative pressure resulted from suction. The original wool mats then pass through pendulum, crimping and pressing process, get into the curing oven through which the wool mats are cured and shape up to different kinds of products such as board, mat and pipe section etc with different usage.
The properties of non-combustibility, high-temperature resistance and porous fiber construction of rock wool products, make them have very good performance on fire resistance, thermal insulation, and acoustic insulation. The rock wool products are widely used for industry field, building and marine & offshore field to increase the energy efficiency, decrease pollution agent discharge, and improve fire safe situation. Meanwhile, some rock wool products can also be used as the planting substrate for many kinds of vegetables, flowers, and fruits.
