摘　　要：分析果胶酶处理果胶类物质(从浆料中获得)、白水和DCS的效果,揭示果胶酶降解果胶类物质的规律以及对造纸白水性质的影响,特别是对白水阳离子需求量(CD)的影响。结果表明,果胶酶可以降解BCTMP浆料中的果胶类物质生成半乳糖醛酸;果胶酶用量为125u时,白水中DCS的CD降低40%左右,DCS胶体平均粒径降低,浊度降低。Pectinase could decrease the cationic demand of papermaking white water. The degradation of pectinase to the pectin and their effect on cationic demand were studied by ion-exchange chromatography and colloidal titration. It was found pectinase KJ-544010 is the best for hydrolyzing polygalactose which creates galactose acids and decreases cationic demand; about 40 percent decrease of CD value of DCS in white water, decrease in average particle size and turbidities of DCS colloid were founded at pectinase dosage of 125 unit.
