- 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: 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
- Rock wool with a light weight, non-combustible, small thermal conductivity, sound absorption performance, good chemical stability and so on
- 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.
