- Q:Rock wool products and aluminum silicate acupuncture blankets are same
- No, rock wool is ore blown wire, aluminum silicate is coke gem
- Q:What role does dolomite play in rock wool products?
- What role does dolomite play in rock wool products?
- Q:Rock wool board is inorganic composite insulation material
- Insulation material A-level fire is organic meet the inorganic meet resolutely
- Q:Rock wool products are divided into several categories
- In the rock wool by adding special adhesive can be processed into rock wool board, rock wool stave, rock wool insulation and other products, as the building insulation, insulation, cold, sound-absorbing material
- Q:The difference between rock wool and rock wool
- Flexible, medium strength rock wool board: for building walls / roof insulation, fire, sound, such as curtain wall, wall partitions, elevator wells, etc
- Q:What does the rock wool board look like?
- Rock wool board to basalt as a material, after high temperature melting processing into artificial inorganic fibers, with a light weight, thermal conductivity, heat absorption, non-flammable characteristics
- 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.
