摘　　要：采用脂肪酶分别对废纸脱墨浆样中的胶黏物以及含酯键的胶黏物模型物进行处理。结果表明:脂肪酶对浆样中的胶黏物有一定的去除作用,不同酶处理效果不同,但在通常的制浆条件下很难实现较好的处理效果;脂肪酶对含酯键的模型物的研究表明,含酯键物质分子越分散越有利于反应的进行,因此对胶黏物的控制应尽量使胶黏物在浆中的分散度增加。Lipase was used to treat stickies and the model of stickies contains ester bond. The result shows that lipase could remove some of stickies in the pulp and the different results based on the different type of it. But it＇s difficult to obtain the distinct result under normal condition. According to the result of study of the model stickies with lipase, the more the molecule of the model stickies dispersed, the better the result can be obtained.
