Products Description
Production Process:
Ceramic fiber board is made by wet vacuum forming process or dry manufacturing process.
The strength of this kind of product is higher than that of fiber blanket and vacuum forming felt, so it is suitable for the high temperature field with steel strength requirement.
Product Characteristics:
Low thermal conductivity, low heat density
Excellent thermal stability and thermal shock resistance
High compressive strength and good toughness
Product Application:
Thermal insulation of high temperature equipment
Industrial kiln backing material, masonry insulation layer
Heat insulating material heating device
Thermal insulation and fire-retardant materials for metallurgy, petrochemical, glass, ceramics, non-ferrous metals and other industries
Kiln lining, kiln car, door baffle and temperature partition board of high temperature kiln
Heat insulation, fire prevention, sound insulation and insulation in aerospace and shipbuilding industry
