Hard basalt rock wool board manufacturers offer price per square meter price

The difference between wool and slag wool and contrast by analyzing and comparing rock wool, slag wool and major chemical components of raw materials and fibers, color, acidity coefficient, PH value, water resistance, heat resistance and corrosion resistance, etc., It outlines the performance and characteristics of each rock wool and slag wool between. 1. Define the Rockwool: natural rocks such as basalt, diabase, dolomite as the main raw material, inorganic fiber by melt fibrosis made of. Slag wool: the use of industrial waste slag (blast furnace slag or aluminum slag, etc.) as the main raw material, inorganic fiber by melt fibrosis made of. Mineral wool: the national standard did not "mineral wool" that definition, but only to define slag wool and rock wool. However, under normal circumstances, slag wool and rock wool used to be collectively referred to as mineral wool. So easy to be both seen the same thing. 2. The main raw wool: basalt, diabase, gabbro, dolomite, limestone and other natural minerals. General use coke as fuel in cupola melted. Slag wool: blast furnace slag, blast furnace slag, slag iron alloy, nonferrous metal smelting slag, brick slag, iron slag, fly ash, slag, etc. whirlwind. General use coke as fuel in cupola melted. Hard Rock wool board hard board through the selection of high quality basalt rock wool as the main raw material, using the German ENETEX advanced production lines, European technical standards, after high temperature melting, blowing centrifugal pendulum method to process, and then in the rock wool fibers adding a certain amount of binder dust oil, water repellent, after settlement, curing, cutting and other processes, production and processing thereof. With a non-flammable, non-toxic, low thermal conductivity, water-repellent, acoustic, physical and chemical properties and stability characteristics and through the national GB / T25975-2010 testing standards.
