Refractory Ceramic Fiber Cotton( raw material )

Refractory thermal insulation raw materials-ceramic fiber bulk/ceramic fiber cotton/ceramic fiber wool, for raw materials of ceramic fiber blanket, product

Production technology of ceramic fiber cotton

The common ones are made of hard chamotte clay, which are meltdown in resistance furnaces and processed by blowing or swinging technology.

The high purity and high aluminum ones are made of composite materials of pure alumina and silica powder, which are meltdown in resistance furnaces and processed by blowing or swinging technology.

Zirconium ones are made of composite materials of high purity alumina, silica powder and zircon sands, which are meltdown in resistance furnaces and processed by blowing or swinging technology.

Features of ceramic fiber cotton

needled fiber bulk:

Needled ones have long fibre, low ball sediment and low non-fibre material content. The long fiber produced by untreated swinging fibre forming serves as the filling material of wall linings of heaters such as high-temperature furnace as well as the raw materials of textiles due to its good spinnability.

blown fiber bulk:

The untreated fibre produced by blown fiber forming technology with low ball sediment and no lubricants serves as the filling material of high-temperature furnace and the excellent raw materials of vacuum molding products, fibre spraying and fibre paper.

Typical Application of ceramic fiber bulk

Raw materials of fiber Paper and vacuum forming products

Raw materials of fiber coating materials;

Raw materials of fiber castable and coatings;

High-temperature furnace heating equipment wall lining fillings

Raw materials of fiber textile products

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?: Rock wool is a traditional insulation material, because it is inorganic materials, insulation performance is not very good

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: 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.

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.
