- 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.
- Q:Rock wool products and aluminum silicate acupuncture blankets are same
- No, rock wool is ore blown wire, aluminum silicate is coke gem
- Q:Rock wool products are divided into several categories
- Which rock wool board in the application of more interior decoration. Rock wool board specifications are usually as follows: long (mm) 900,100; width (mm) 500,600,700,800; thick (mm) 30,40,50,60,70
- Q:What does the rock wool board look like?
- The initial development of Hebei Langfang Dacheng in the building is a common type of application for industrial buildings should be consistent with "building insulation materials, the type of application and basic requirements"
- Q:The difference between rock wool and rock wool
- Yanmian tube is a kind of rock wool insulation material mainly used in the pipeline. After the natural basalt is melted by high temperature, the artificial inorganic fiber is made from the high speed centrifugal equipment, and the special binder and dustproof oil are added. Temperature curing, made into a variety of specifications, different requirements of the rock wool insulation tube
- Q:What role does dolomite play in rock wool products?
- Pu hard foam layer can be firmly bonded with the base layer, the adhesive strength can exceed the tear strength of the foam itself, so Pu hard foam and the formation of the base layer, easy to delamination, to avoid the water along the interlayer
- Q:Rock wool board is inorganic composite insulation material
- Rock wool composite insulation material depends on what you compound the material
- Q:Rock wool insulation material fire rating is how much
- Rock wool products are: rock wool board, rock wool tube, rock wool felt, rock wool insulation and so on
