Aluminum silicate fiberboard
Aluminum silicate fiberboard
Classification temperature:
Ordinary aluminum silicate fiberboard “1100℃”
Standard aluminum silicate fiberboard 1260℃
High-purity aluminum silicate fiberboard 1260℃
High-aluminum type aluminum silicate fiberboard 1360℃
Zirconium-containing aluminum silicate fiberboard 1430℃
Production Process:
Various aluminum silicate fiberboards are made of the corresponding ordinary, standard, high-purity, and zirconium-containing aluminum silicate fiber cotton as raw materials, and are refined by vacuum forming or dry process through drying and machining. To
All kinds of aluminum silicate fiberboards not only have the excellent properties of corresponding bulk aluminum silicate fiber cotton, but also have hard texture, excellent toughness and strength, and excellent wind erosion resistance. It is non-expandable, light in weight, convenient in construction, and can be cut and bent at will. It is an ideal energy-saving material for kilns, pipelines and other thermal insulation equipment. To
Operating temperature:
It depends on the type of heat source, ambient atmosphere and material usage conditions. To
Technical characteristics:
Low thermal conductivity, low heat capacity
Excellent thermal stability and thermal shock resistance
High compressive strength and good toughness
Application:
Industrial kiln wall lining, masonry insulation layer
Kiln lining, kiln car, door baffle of high-temperature kiln, furnace temperature partition plate
Heat insulation and heat preservation of high temperature and high heat equipment
Aerospace, shipbuilding industry heat insulation, fire protection, sound insulation, insulation
