Graphite felt definition authenticity

In the vacuum or inert atmosphere, the carbon felt is more than 2000 DEG C, and the carbon felt is higher than that of carbon felt, which is more than 99%. In the late 60s, the world has been goods supply. Because of the different selection of raw graphite felt felt for PAN based graphite felt and viscose based graphite felt two.

The process of polyacrylonitrile based carbon felt or rayon based carbon felt is cut into the required size, the container into a cylinder made of a graphite, graphite container in a high temperature furnace (high temperature furnace for graphite tube furnace, intermediate frequency and high frequency induction furnace or other heating in the form of Gao Wenlu), with the vacuum or protection of high purity inert gas, heating rate from 100 to 300 DEG /h heating to 2200 to 2500 DEG C, natural cooling to 100 DEG C to obtain.

PAN based graphite felt strong than viscose based graphite felt strong antioxidant capacity, but poor flexibility, large volume density, good thermal insulation properties. They have the advantages of high purity, high temperature resistance, corrosion resistance, non melting and so on, but also have the advantages of flexibility, can be folded, cut, and the use of graphite yarn stitching. The graphite felt is mainly used as the thermal insulation material of monocrystalline silicon smelting furnace. A filter material that can be used as a highly corrosive chemical reagent in the chemical industry. Graphite felt in non oxidizing atmosphere, the temperature can reach 3000 degrees celsius.
