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?: Rock wool board to basalt as a material, after high temperature melting processing into artificial inorganic fibers, with a light weight, thermal conductivity, heat absorption, non-flammable characteristics

Q: What role does dolomite play in rock wool products?: What role does dolomite play in rock wool products?

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: Burning performance: Combustion performance refers to all the physical and chemical changes that occur when the building material is burned or in case of fire. This performance is caused by the fire and flame propagation of the material surface, heat, smoke, carbonization, weight loss, and toxicity And other characteristics to measure. The burning performance of the products of rock wool products is zero.

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.

Q: Rock wool products and aluminum silicate acupuncture blankets are same: Rock wool products and aluminum silicate acupuncture blankets are same

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
