Activated carbon fiber obtained by carbonizing and activating mixed fibers, process for producing the activated carbon fiber, carbonization and activation device for the raw fiber
Activated carbon fiber obtained by carbonizing and activating mixed fibers, process for producing the activated carbon fiber, carbonization and activation device for the raw fiber
It may be made of woven or nonwoven fabric raw materials processed by mixing appropriate proportions of synthetic fibers such as rayon fiber, phenol resin fiber, polyacrylonitrile fiber, polyester fiber, nylon, etc. and cotton fiber, or a special wood fiber or pitch fiber Activated carbon fibers obtained by processes such as carbonization and activation by using fibers obtained by mixing and processing the fibers at proper ratios, and a method for producing the activated carbon fibers, carbonization of the raw fibers, and activation of carbon fibers and oxidizing gases and inert gases to a predetermined temperature And an oxidizing gas or the like designed to keep the quality of the product uniform by preheating and uniformly spraying the same. At this time, waste fiber generated from the fiber processing companies of the used fibers and waste resources to be disposed of at home and offices are used as the main raw materials, and the production cost is reduced and the waste is recycled.;The carbonization conditions of the raw fiber and carbon fiber are most important in the manufacturing process. The carbonization and activation methods are improved by controlling the amount of carbonization, heating temperature, heating time and oxidizing gas in the activation process. Gas and so on. In addition, the deposition method of the dehydrating agent, the mixing ratio of the oxidizing gas and the inert gas, and the injection amount were also controlled. The activated carbon fibers obtained by this method had a high specific surface area and thus had excellent adsorption performance and high tensile strength.;These products can be used for advanced water treatment of drinking water, advanced treatment of waste water and sewage, air purification, odor prevention, removal of harmful substances, decolorization and deodorization. Therefore, the present invention can be applied not only to the treatment facilities but also to remove harmful substances, odors, etc. in water purifiers, air cleaners, air conditioners, refrigerators, air conditioning facilities, masks, and cigarette filters.
