1. Insulation performance: good thermal insulation performance is the basic characteristics of rock wool and slag cotton products. Their thermal conductivity is usually between 0.03 and 0.047 W/(moK) under normal temperature conditions (about 25 °C).
2. Combustion performance: The burning performance of rock wool and slag cotton products depends on the amount of flammable adhesive. Rock wool and slag wool are inherently inorganic silicate fibers, which are non-flammable. In the process of processing into products, organic binders or additives are sometimes added, which have certain effects on the combustion properties of the products.
3. Sound insulation performance: Rock wool and slag cotton products have excellent sound insulation and sound absorption performance. The sound absorption mechanism is that this product has a porous structure. When sound waves pass, friction is generated due to the action of flow resistance, so that the sound energy is Part of it is absorbed by the fiber, which hinders the transmission of sound waves.
