Cheap Basalt Rock Wool Board Rock Wool Wired Blanket Fireproof Insulated Rock Wool
Introduction
Rock wool products are mainly made of high-quality basalt, dolomite, and other raw materials. After being melted at high temperatures above 1450 ℃, they are centrifuged into fibers using an internationally advanced four axis centrifuge at high speed. At the same time, a certain amount of binder, dustproof oil, and hydrophobic agent are sprayed into them, collected by a cotton collector, processed by a pendulum method, and then solidified and cut using a three-dimensional method to form rock wool products of different specifications and purposes.
