Reinforced Composite Hard 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. Metal heat treatment: heat treatment furnace, sintering furnace, brazing furnace
4. Carbon fiber production: induction heating or resistance heating carbonization furnace, graphitization furnace
5. The production of composite materials: pyrolytic carbon and pyrolytic graphite, chemical vapor deposition, or other composite materials
6. Energy materials: vanadium or other redox battery materials
The density of this product is 0.25-0.30g / cm3. The surface can be coated with graphite paper or carbon cloth, carbon cloth and graphite paper, graphite paper can be sandwiched between each felt. It can prevent surface fluff, gas leakage (convection), and protect its surface (prevent loss) and increase the strength of hard felt.
Reinforced Composite Hard Felt: small heat capacity, low thermal conductivity, good thermal insulation performance, rapid heating and rapid cooling without deformation, it is an ideal thermal insulation material for vacuum quench furnace, vacuum brazing furnace, vacuum sintering furnace, and vacuum series high temperature furnace. It is made by primary and secondary high-temperature treatment, and its anti-ablation performance, thermal shock resistance, airflow erosion resistance and thermal insulation performance are excellent.
It has the advantages of high rigidity, self-supporting, high strength, no short fiber loss, and low thermal conductivity that traditional insulation materials do not have.
