STA High rigidity Low Thermal Conductivity Ceramic Fiber Insulation Board for vacuum furnace
Ceramic Fiber Insulation Board for vacuum furnace Introduction:
Ceramic Fiber Insulation Board for vacuum furnace is a lightweight refractory material processed with alumina-silica fibers for applications at temperatures up to 1430C. it manufactured and designed for the thermal applications requesting high demands on rigidity, the thermal insulation properties and abrasion resistance of ceramic fiber board have been further improved due to the higher density.
Ceramic Fiber Insulation Board for vacuum furnace is a vacuum formed product that resists higher gas velocities than ceramic fiber blanket. It is ideal for furnace, boiler duct and stack lining thanks to its low thermal conductivity and low heat storage, which makes the shorter cycles times and quicker access for maintenance in the industrial furnaces possible.
Ceramic Fiber Insulation Board for vacuum furnace Feature:
- Low thermal conductivity
- Low thermal capacity
- Good thermal shock resistance
- Flexible and tearing resistance
- No asbestos and anti-corrosive
- Good electric and sound insulation
- Good mechanical working performance
- Even thickness and density
Ceramic Fiber Insulation Board for vacuum furnace Application:
- Insulation for high temperature furnaces.
- Surface insulation of industrial kilns.
- Fire-barrier material for multi-temperature zones furnace.
- Backing insulation of petroleum, chemical and metallurgical furnace.
- High temperature sintering sagger.
- High temperature sealing for machine and precision mold.
