Q: What does the rock wool board look like?: June 1981 test success Rock wool board is a new type of insulation, fire, sound absorption material.

Q: What role does dolomite play in rock wool products?: Polyurethane foam is a dense structure of the microporous foam, closed cell rate of 92% or more, with a smooth self-crust, is a good impervious material, in the construction of direct spraying molding technology, so Pu hard layer did not fight The overall formation of the entire impermeability of the seam, fundamentally put an end to the possibility of deepening the roof water from the seam

Q: Rock wool products are divided into several categories: Rock wool with a light weight, non-combustible, small thermal conductivity, sound absorption performance, good chemical stability and so on

Q: How to judge the quality of rock wool: Burning performance: Combustion performance refers to all the physical and chemical changes that occur when the building material is burned or in case of fire. This performance is caused by the fire and flame propagation of the material surface, heat, smoke, carbonization, weight loss, and toxicity And other characteristics to measure. The burning performance of the products of rock wool products is zero.
