Rock Wool Sandwich Wall Panel

Rock Wool Sandwich Wall Panel is an inorganic fiber made from natural rocks such as basalt, gabbro, dolomite, iron ore, bauxite, etc. as the main raw material, which is melted and fibrillated at high temperature. The use of rock wool porous structure, sound propagation speed in the air is less than the speed of propagation in the solid, when the sound wave through, due to the role of friction generated by the role of flow resistance, so that part of the sound energy for the fibers to be absorbed, impeding the transmission of sound waves made of the principle of sound insulation materials.

Overview

Production:

Natural rock, ore and other raw materials, melting in the cupola or other pool kiln (temperature below 2000 ℃), with 50 atmospheric pressure pressure, strong blowing, sudden cooling into fiber. Or dumping method, the molten liquid stream off in the multi-stage rotary rotor, by centrifugal force thrown into fibers, the diameter of the general 3 ~ 9 microns, capacity 50 ~ 200 kg / m ^ 3.

Application:

Rock wool can be made into strips, belts, ropes, felts, blankets, mats, mats, tubes and boards.

It is used in single crystal furnace, metallurgical casting, oil cracking and space technology as ablation-resistant and high-temperature-resistant heat insulation material;

Sound-absorbing and heat-insulating materials for buildings and equipments;

As well as natural asbestos substitutes for cement products, rubber reinforcing materials and high-temperature sealing materials, high-temperature filtration materials and high-temperature catalyst carriers.
