耐水性が向上する。In order to solve this problem, when producing activated carbon molded products, volatile salts of carboxymethyl cellulose (hereinafter referred to as CMC)
- When a volatile salt (hereinafter abbreviated as "volatile salt") is used as a binder, the volatile substance evaporates during heating and pores are formed in the binder film covering the activated carbon surface, which does not impede the adsorption performance of activated carbon. It is also known as No. 61-52739. CMC-volatile salt becomes water-insoluble by volatilizing volatile substances, so water resistance is improved compared to when using general water-soluble polymers such as polyvinyl alcohol, sodium salt of carboxymethyl cellulose, and sodium alginate. .

The blending ratio of the binder is preferably in the range of 10 to 900 parts by weight of CMC-volatile salt per 100 parts by weight of the water-insoluble synthetic resin.
