Graphite hard felt (commonly known as carbon fiber composite hard felt, cured felt, carbon fiber-reinforced, etc.) is made by special process that integrates graphite paper, polyacrylonitrile-based carbon felt, and polyacrylonitrile-based carbon cloth into one body, curing After molding, then primary and secondary high-temperature treatment.
Graphite Hard Felt Sheet is mainly used in vacuum and various metallurgical industrial furnaces (single crystal growth furnace, polycrystalline casting furnace, polycrystalline reduction furnace, polycrystalline ingot furnace, high-pressure gas quenching furnace, hot isostatic pressing furnace, thermal balance furnace, low-pressure sinter Furnace, pressure vacuum sintering furnace, etc. It is also widely used in defense, metallurgy, chemical industry, and other industries. Especially with the rapid development of polycrystalline silicon and monocrystalline silicon industries, as an ideal material for thermal insulation of high-temperature furnaces, the demand for high-quality hard carbon fiber felt has reached an unprecedented height.
Polyacrylonitrile-based graphite felt is stronger and more resistant to oxidation than viscose-based graphite felt, but it has poor flexibility, large bulk density, and good thermal insulation performance. In addition to their high purity, high-temperature resistance, corrosion resistance, and non-melting characteristics, they also have the advantages of elasticity, foldability, tailoring, and sewing with graphite yarn.
The main use of Graphite Hard Felt Sheet is as a thermal insulation material for single crystal silicon smelting furnace. In the chemical industry, it can be used as a filter material for high purity corrosive chemical reagents. Under the non-oxidizing atmosphere, the temperature of the graphite felt can reach 2850℃.
Physical and chemical indicators:
Temperature resistance: 1800 ℃ in vacuum, 2850 ℃ in inert gas
Graphite Felt Application:
1. Aerospace industry: hot isostatic pressing furnace, heat treatment, sintering, brazing, hot pressing furnace 2. Semiconductor industry: drawing silicon single crystal furnace, vacuum metallurgy 3.
