Ceramic Fiber Bulks are manufactured to be used as feedstock in manufacturing processes or other applications made of high purity composite raw materials, melted in the resistance furnaces and processed by blowing or spinning technology.
Application:
The color is white, the size is accurate, the cutting is easy to install, the construction is convenient, and the working hours are saved.
Does not contain any binder, long-term use in neutral, oxidizing atmosphere
Low heat capacity, low thermal conductivity, high refractoriness and high heat sensitivity
Excellent resistance to wind erosion and mechanical shock resistance
Excellent sound absorption and fire resistance
Automated production, stable density and performance
Features:
Industrial furnace, boiler lining, backing insulation, fireproof insulation
Thermal insulation of thermal equipment such as steam engine gas engine
High temperature pipe flexible insulation material; high temperature gasket; high temperature filtration
Thermal reactor thermal insulation
Fire protection of various industrial equipment, heat insulation of electrical components
Insulation equipment for incineration equipment
Raw materials for modules, folding blocks and veneers
Investment casting insulation heat insulation
Classification Temperature: 1050℃, 1260 ℃,1360℃,1400℃, 1430 ℃
Specifications and packaging
All kinds of fiber bulk are shipped in 20kg carton or 60-80kg package, and can also be packed in compression.
