Ceramic fibre blanket
Ceramic fibre blanket
Description
The ceramic fiber blanket is made by high-temperature melt spraying or spinning of raw materials into fibers, and is made by double-sided needle punching. The color is white, the size is regular, and it integrates fire resistance, heat insulation and heat preservation functions. The ceramic fiber blanket can maintain good tensile strength, toughness and fiber structure when used in a neutral and oxidizing atmosphere.
After the double-sided needling process, the degree of fiber interweaving, delamination resistance, tensile strength and surface flatness are greatly improved. The fiber blanket does not contain any organic bonding agent to ensure that the ceramic fiber blanket has good manufacturability and stability under high temperature and low temperature conditions.
The ceramic fiber blanket is white in color and regular in size. It integrates fire resistance, heat insulation and heat preservation, and does not contain a binder. When used in a neutral, oxidizing atmosphere, it can maintain good tensile strength, toughness and fiber structure. Temperature resistance is 950-1400℃, with chemical stability, thermal stability, sound absorption and noise reduction performance, high tensile strength, low thermal conductivity, low heat capacity, etc.
Features
Excellent chemical stability / Nonflammable / Low thermal conductivity
Excellent thermal insulation performance / Excellent tensile strength and resilience / Excellent sound insulation and thermal shock resistance
Application
High-temperature thermal insulation for aerospace, steel, and petrochemical; fire and thermal insulation of military equipment; thermal insulation of industrial kilns and heating device wall linings and backing; thermal insulation of high-temperature equipment; thermal insulation of high-temperature pipelines; thermal insulation of electrical components; high-temperature gaskets; modules , Folding block raw materials.
