Description

technical field

[0001] The invention relates to a filter paper, in particular to an activated carbon filter paper. Background technique

[0002] Nowadays, the society has higher and higher requirements for the quality of urban tap water, and it is required to meet the standard of direct drinking. The traditional water purification method mainly uses the high adsorption performance of the porosity of activated carbon particles to make activated carbon columns or activated carbon particle filter layers. Outsourcing means non-woven fabrics to treat tap water. In recent years, due to the miniaturization and convenience requirements for household water purifiers, developed countries such as Europe and the United States have begun to produce special activated carbon filter paper for water purifiers.

[0003] Activated carbon filter paper is a kind of filter material with a porous network structure, which is made by adding activated carbon powder, chemical fiber and functional add...
