- Q: What role does dolomite play in rock wool products?
- Rock wool is a traditional insulation material, because it is inorganic materials, insulation performance is not very good
- 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: How to judge the quality of rock wool
- Heat load shrinkage temperature: heat load shrinkage temperature used to characterize the rock wool board moisture and heat stability, is to wet the rock wool product samples soaked in the gradual heating of water, rock wool products at a temperature of 643 degrees will begin to shrink , So rock wool products load shrinkage temperature of 643 degrees, that is to say in the outside temperature of 643 degrees when the rock wool board will be deformed.
