Title (EN) METHOD FOR PRODUCING GEL OF CARBOXYMETHYL CELLULOSE ALKALI METAL SALT
(FR) PROCÉDÉ DE FABRICATION D'UN GEL DE SEL DE MÉTAL ALCALIN DE CARBOXYMÉTHYL CELLULOSE
(JA) カルボキシメチルセルロースアルカリ金属塩のゲルの製造方法
Abstract: front page image
(EN)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.
(FR)L'invention porte sur un procédé de fabrication d'un gel d'un sel de métal alcalin de carboxyméthyl cellulose par lequel un gel de grande élasticité et de force élevée, et de capacité de rétention d'eau et de durabilité élevées, peut être obtenu facilement à faible coût. Le procédé de fabrication d'un gel d'un sel de métal alcalin de carboxyméthyl cellulose comporte le malaxage préalable d'un mélange contenant un sel de métal alcalin de carboxyméthyl cellulose et un agent de rétention d'eau, et par la suite le malaxage du mélange préalablement malaxé avec une solution aqueuse acide pour former un gel.
(JA) 弾性と強度が高く、しかも保水性および耐久性に優れたゲルを安価に且つ簡便に得ることができるカルボキシメチルセルロースアルカリ金属塩のゲルの製造方法を提供する。 本発明のカルボキシメチルセルロースアルカリ金属塩のゲルの製造方法は、カルボキシメチルセルロースアルカリ金属塩と保水剤とを含む混合物を予め混練し、次いで、混練後の混合物と、酸水溶液とを混練してゲルを得ることを特徴とする。
