Soft Felt - Standard Carbon Felt
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. flame retardant material in the insulation industry;
2. porous material, for chemical industry catalyst carrier
3. corrosion-resistant material for the lining or external protective layer of composite materials.
4. conductive, absorbing and absorbing material in aviation, batteries, electrodes (such as electrode tubes, electrode sticks, etc.);
5. 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 contain
Activated carbon fiber (ACF) is a new type of high-efficiency adsorption material that surpasses activated carbon (GAC) and it is a new type of replacement product. It has a highly developed microporous structure, large adsorption capacity, fast absorption speed, and a good purification effect. It can be processed into various specifications of felt, silk, and cloth. The product has the characteristics of heat resistance, acid resistance, and alkali resistance.
