Problems solved by technology

However, in practical applications, when the amount of activated carbon powder is large, there is usually the problem that the strength of the filter paper is not enough and it is easy to lose powder. However, reducing the amount of activated carbon powder and increasing the amount of fiber pulp will lead to a decrease in the adsorption and filtration efficiency of the filter paper and cannot meet the use requirements. difficult to balance

Abstract

The invention discloses high-performance activated carbon paper. The high-performance activated carbon paper comprises activated carbon, plant celluloses, polyester fiber pulp, PE / PET composite chopped fibers and sizing agents. The high-performance activated carbon paper is obtained by the steps of preparation of plant cellulose pulp, preparation of the polyester fiber pulp, and preparing, dryingand forming of activated carbon pulp. The high-performance activated carbon paper, as a functional filter material, has an adsorption function of the activated carbon and functions of intercepting andfiltering out suspended particulate matters and filtering out residues; the iodine value of the filter material reaches 550-800mg / g, and benzene adsorption rate can reach 18-28%; the high-performanceactivated carbon paper is widely applied to various industries such as air purification and water treatment, filtration and purification, can remove residual chlorine, TOC (total organic carbon), chemical pollutants and the like in water effectively, has good decoloration effect, and can remove substances such as formaldehyde, benzene, ammonia and TVOC (total volatile organic compounds) in the air. The filter material in the form is convenient to cut, roll, fold and clean, and environment protection and rapidness are achieved.

Description

technical field [0001] The invention relates to the technical field of activated carbon paper preparation, in particular to a high-performance activated carbon paper and a production method thereof. Background technique [0002] Activated carbon (Activated Carbon, AC) is a porous functional material with developed pore structure. Activated carbon filter paper prepared by utilizing the characteristics of activated carbon is a functional filter material, which can be used for air and water purification and military chemical protection, etc. field, with broad market prospects. [0003] At present, most of the common activated carbon filter papers on the market use plant fiber pulp as the carrier, and the activated carbon powder is added to the pulp and made by paper machine. The filtering mechanism is that the activated carbon particles in the paper have a porous structure and a very large specific surface area. It has a strong adsorption capacity for certain components in the...
