Soft Felt - Standard Carbon Felt
Introduction:
Carbon fiber felt is a felt made of carbon fiber. It has a broad absorption spectrum with a large capacity. The adsorption capacity of gasoline, aldehydes, phenols, alcohols, olefins and other organic vapors is several times to dozens of times larger than that of activated carbon (GAC). It has good adsorption for inorganic gases (such as No, N, HF, HCl, etc.).

Application :
1. It can be used as a flame retardant material in the insulation industry;
2. As a porous material, it can be used as a catalyst carrier for the chemical industry;
3. It can be used as a corrosion-resistant material for the lining or external protective layer of composite materials.
4. It can be widely used as a conductive, absorbing and absorbing material in aviation, batteries, electrodes (such as electrode tubes, electrode sticks, etc.); at present, applications related to conductive concrete are also developing rapidly.
Features:
The adsorption capacity of COD, BOD and oil in aqueous solution is much higher than GAC. The adsorption resistance is small, the speed is fast, and the absorption is rapid and thorough.
Production method:
The manufacturing methods are: (1) needle punching after air-laid short carbon fiber; (2) carbonization of pre-oxygen silk felt; (3) pre-oxidation and carbonization of polyacrylonitrile fiber felt. It used as insulation material for vacuum furnace and inert gas furnace, hot gas or liquid and molten metal filter material, fuel cell porous electrode, catalyst carrier, composite material lining and composite material of corrosion-resistant contai
