The modification reaction included hydroxymethylation of gluten and cationic activation with epichlorohydrin.
采用廉价可生物降解的小麦谷朊蛋白为原料，经过羟甲基化和阳离子化改性合成类似聚酰胺聚胺环氧氯丙烷的纸张增强剂。
The fundamentals involved the technologies were studied. The relationship of collectors, dispersant and pH can be determined by solution chemical calculation in the direct flotation of bauxite by anionic collectors. The PZC of minerals and the p K a of collectors are the dominating control parameter in the reverse flotation by cationic collectors. The lead salt and calcium salt are effective activators in the metal ions activation flotation by the anionic collectors.
结果表明：通过溶液化学计算可确定阴离子捕收剂正浮选脱硅时捕收剂，分散剂和pH三者之间的匹配关系；矿物的PZC与捕收剂的p K a值是阳离子捕收剂反浮选的主要控制参数；阴离子捕收剂反浮选时，铅盐和钙盐是浮选铝硅酸盐较理想的活化剂。
