Q: What does the rock wool board look like?: What does the rock wool board look like?

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 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.

Q: The difference between rock wool and rock wool: The difference between rock wool and rock wool

Q: Rock wool products and aluminum silicate acupuncture blankets are same: No, rock wool is the external wall insulation, silicate Lu power plant with more

Q: Rock wool insulation material fire rating is how much: Yanmian, mineral wool and its products are slag and basalt and other natural ore as the main raw material, the high temperature melt fiber, adding the right amount of adhesive processing
