The fiber is slender and the average diameter is ≤5μm, which is lower than the national standard ≤6μm; the slag ball content is low, about 5%, which is lower than the national standard ≤7%. The measured thermal conductivity is 0.035-0.043w/m·
Fire prevention
﹀
Using natural basalt as the main raw material, the melting temperature is greater than 1000 ℃, and the organic content is extremely low. It is a non-combustible A-level fireproof and thermal insulation material. It has excellent high temperature resistance and low thermal...
Waterproof
﹀
Hydrophobicity ≥99%; short-term water absorption (partially immersed in water 24h) ≤0.4kg/㎡; long-term water absorption (completely immersed in water 28d) ≤1.0kg/㎡; if the product is wetted by high-pressure water, its performance will not be affected after drying. Will not swell...
Moisture-proof
﹀
Rock wool products are fully immersed in an environment with a temperature of 50°C and a relative humidity of 95% for 25mm for 2 hours, and the volumetric moisture absorption rate is less than 5%; in accordance with the national standard GB/T25975-2018 test, the mass moisture...
Sound absorption and noise reduction
﹀
Rock wool products are made of a large number of slender fibers to form a porous interconnected tiny air gap structure. It absorbs sound by converting sound energy into heat and greatly reduces sound wave reflection. It is a cost-effective sound absorption and noise reduction and...
Good air permeability
﹀
The fiber structure of the rock wool board has good air permeability, and the water vapor can pass through freely. It can well cooperate with the respiration of the brick-concrete wall or the concrete wall, so that the room can maintain a comfortable dry and humid environment.
Stable chemical and physical properties
﹀
The acidity coefficient of rock wool products is an important indicator to measure the chemical stability and durability of rock wool boards. The acidity coefficient is ≥1.8, so it has good high temperature thermal stability, durability and resistance to high temperature shrinkage.
