METHOD FOR PRODUCING GEL OF CARBOXYMETHYL CELLULOSE ALKALI METAL SALT

摘要

Provided is a method for producing a gel of a carboxymethyl cellulose alkali metal salt by which a gel having high elasticity and high strength, and also having high water retentivity and high durability can be obtained easily at low cost. The method for producing a gel of a carboxymethyl cellulose alkali metal salt comprises previously kneading a mixture containing a carboxymethyl cellulose alkali metal salt and a water retention agent, and subsequently kneading the previously kneaded mixture with an acid aqueous solution to form a gel.
