impregnated activated carbon 。 Universal impregnated carbon, used for filling the collective protection canister; Special impregnated carbon is used for special purpose canister, fixedly installed agent filtration equipment and collective protection canister. Such as nuclear industry rescue, rocket propellant protection, naval nuclear submarine, aerospace filtering equipment, etc.

Universal impregnated carbon: The particle size distribution of universal impregnated carbon shall be reasonable and clearly specified, and the strength, moisture and water capacity shall comply with the regulations.

Special impregnated carbon: The technical indicators of special impregnated carbon shall be specified according to the purpose of use.

Optimum impregnation Activated carbon It is made of activated carbon with high adsorption performance as raw material, impregnated with potassium hydroxide, hydrogen peroxide and other solutions, and then refined by 130 ° - 180 ° cremation drying. Impregnated activated carbon is widely used to remove gases and vapors in air or other air streams, such as hydrogen sulfide, sulfur dioxide, etc. Liquid phase adsorption, air purification, coal based activated carbon products have large specific surface area, suitable pore structure, high mechanical strength, can withstand high temperature, high pressure, not easy to break, long service life and other characteristics.
