Product introduction of ceramic fiber blanket
The ceramic fiber blanket is made of a special silicate aluminum, which is made by a special process of double-sided needles. After the double-sided sewing technology is adopted, the adhesion degree, acid resistance, tensile strength and plane straightness of the fiber are significantly improved. The fiber does not contain any organic compound to ensure good structure of ceramic fiber and high and low temperature resistance.
Features of ceramic fiber blanket
White, orderly in size, and integrated with fire resistance, heat insulation and thermal insulation. No adhesive. Long term use of neutral oxidizing atmosphere can maintain strength, flexibility and fiber. Resistance to 950-1400 ℃.
Applications of ceramic fiber blanket
Application of ceramic fiber ceramic carpet: space insulation, steel insulation and petrochemical insulation; Thermal insulation of military equipment; Industrial furnace, heater shell and insulation wall protection; Thermal insulation and heating of equipment; High temperature pipeline insulation; Fire and heat insulation of electrical appliances; Heat treatment; Module for folding the components of the block.
