Cherry blossomsRock wool board: it is already selected high-quality basalt as main raw material, melting the day after tomorrow, the four roller centrifugal cotton process advanced, the basalt melt left pull into 4-7um discontinuous fibers, binder and adding wool fibers in a certain amount of dust, oil, water repellent agent, after the settlement, curing and cutting process, according to the different uses made of different density.
2．combustion performanceThe combustion performance of rock wool and slag cotton products depends on the amount of combustible adhesive. Rock wool, slag wool belongs to inorganic silicate fiber, nonflammable, processed into products in the process, sometimes adding organic binder or additives, will influence the combustion performance of these products.
3Sound insulation performance: rock wool, slag, cotton products have excellentsound insulationandSound absorptionThe mechanism of sound absorption is that the product has porous structure, when the sound wave passesFlow resistanceThe role of frictionSoundPart of the fibers are absorbed, hindering the transmission of sound waves.
