【摘要】 分析果胶酶处理果胶类物质(从浆料中获得)、白水和DCS水的效果,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,特别是对阳离子需求量(CD)的影响。离子交换层析分析表明,果胶酶可以水解聚半乳糖醛酸类物质生成半乳糖醛酸。果胶酶KJ-544010可以明显降低DCS水的CD值,最高CD降低幅度可达到40%,而且果胶酶处理对DCS胶体粒度分布等性质也有影响。更多还原

【Abstract】 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 pectineas KJ-544010 is the best pectinases for hydrolyzing polygalactose which creates galactose acids and decreases cationic demand.About 40 percent of CD values decrease and the change of the distributions of DCS particle sizes were founded at pectinase dosage of 100u based on 120mL DCS water.更多还原
