を泡状にしてスプレーして直ちに使用しなければならな
かった。In the case of using a cleaning agent having a high water content, in order to suppress the absorption of water into the hydrolyzed paper, the cleaning agent had to be foamed and sprayed immediately before use to use immediately.
ポリアクリルアミドのような乾燥紙力増強剤を用いれ
ば、少量の水を含浸した状態でも清掃作業に耐え得るよ
うな強度を可能にするが、ともするとシートの水解性を
不良にしてしまう。The use of a dry paper strengthening agent such as polyacrylamide enables the strength to withstand the cleaning work even when impregnated with a small amount of water, but at the same time, the water decomposability of the sheet becomes poor.
このように従来の乾燥紙力増強剤では、水分含量の高い
