Specifications

Characteristic:
1.Series products of different bulk density
2.Direct contact with the flame
3.High temperature resistance

The mullite insulating brick which is produced by synthetic mullite sand and polystyrene sphere has better performance than clay insulating brick and high alumina insulating brick.It can be used in the lining of middle temperature furnace.And it has good thermal shock resistance.This product is pure white product,and the content of Fe2O3 and impurity is lower.It is widely used becase of its good performance of thermal current erosion resistance and industrial waste gas erosion resistance.

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: Rock wool products, the important content of rock wool products, the density range is kg / m3 100-250 ± 15%, in this density of rock wool board to meet product quality requirements

Q: The difference between rock wool and rock wool: Yanmian tube with high strength and good flexibility, with a certain pressure, the pleated treatment of rock wool tube with a large drawing strength, not easy to layer, greatly improving the durability of the durability

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: Fire protection and noise reduction of the elevator shaft of the building wall, the roof of the insulation, the firewall, the fire door, the large and medium diameter pipes, the small and medium sized storage tanks, the kilns, the thermal power plants, Boilers and other equipment insulation.
