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.

Technical index:

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

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.).

Taking polyacrylonitrile-based carbon felt as an example
area weight is 500g / m2 and 1000g / m2,
longitudinal and transverse strength (N / mm2) are 0.12, 0.16 and 0.10, 0.12,
elongation at break is 3%, 4% and 18%, 16%
resistivity (Ω·mm) is 4 ~ 6, 3.5 ~ 5.5 and 7 ~ 9, 6 ~ 8 respectively
thermal conductivity is 0.06W / (m·K) (25 ℃)
specific surface area is> 1.5m2 / g
ash content is less than 0.3%
sulfur content is less than 0.03%

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.

Hunan MTR New Material Technology Co., Ltd. (formerly Zhuzhou Green Carbon Fiber Products Co., Ltd.) is a high-temperature furnace thermal insulation material production plant! Our company adheres to the corporate philosophy of singularity, focus and professionalism, and is committed to the continuous development and application of thermal insulation material technology.

The company’s main products include graphite hard felt, reinforced composite hard felt, multi-type composite hard felt (made in an overall shape), graphite felt, high-temperature carbon felt, and other thermal field insulation materials.
