graphite felt
graphite felt
Because of the different selection of raw graphite felt felt for pitch based and PAN based graphite felt and viscose based graphite felt three, is mainly used as heat insulation materials of single crystal silicon smelting furnace. Filtration material for high purity corrosive chemical reagents in the chemical industry.

Carbon felt in vacuum or inert atmosphere after 2000 degrees above temperature treatment for graphite felt, carbon content than carbon felt high, up to more than 99%. World graphite felt supply in late 60s. Because of the different selection of raw graphite felt felt for pitch based and PAN based graphite felt and viscose based graphite felt three.
The Kureha chemical as the representative of the asphalt in the insulation industry as the mainstream [1], and insulation mat basically to China domestic adhesives based, and most of the acrylic as raw material base. 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, no melting, etc., but also have the advantages of elasticity, folding, tailoring and available graphite yarn stitching. Graphite felt is mainly used as monocrystalline silicon smelting furnace insulation materials. Filtration material for high purity corrosive chemical reagents in the chemical industry. Graphite blanket in non oxidizing atmosphere conditions, the use of temperature up to 3000 degrees celsius.
