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?: 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?: Polyurethane is a field foam molding, process equipment is simple, easy to operate, you can spray can also be poured, in any complex roof construction operations

Q: Rock wool products are divided into several categories: Which rock wool board in the application of more interior decoration. Rock wool board specifications are usually as follows: long (mm) 900,100; width (mm) 500,600,700,800; thick (mm) 30,40,50,60,70

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: 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: With low thermal conductivity, the use of high temperature, fire non-flammable, construction convenience, energy-saving effect is remarkable, there is a high cost performance. Adiabatic with rock wool, mineral wool and its products for a variety of pipe insulation and fire protection
