Granular cotton is based on the quality slag as the main raw material. It is melted at high temperature, high speed centrifugation into a fiber and exerted additive .At result, It can be made of Class A non-combustible granular white flock fiber products.

specification model：

project	unit	Parameter
organic density	%	≤1
thermal conductibility	W/(m·k)	≤0.044
shot content	%	≤5
average fiber dia.	μm	≤7

Typical applications:
1,It can be used as the manufacture of mineral wool acoustic board materials.
2, It can be filled in the irregular space in order to achieve the result of fireproof 、insulation, and noise reduction .
3,It can be made into slurry which is sprayed the building or steel surface to obtain fireproof and insulation.
Packaging and storage:
Tai shek granular cotton should be packed with compression and stored indoors.

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?: 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: Rock wool can also be made with glass wool aluminum silicate composite made of rock wool composite insulation pipe.
