2. 4 　硅油用量对消泡性能的影响

试验表明 ,添加少量二甲基硅油即能产生较强的协同消泡效果 ,0. 5 %的加入量是适宜的 ,增加用量 ,

消泡效力增加不明显 ,且经济上不合算.

　结　　论

本消泡剂是一种以脂肪酸二酰胺为主体的固体分散油基型消泡剂. 乙撑双硬脂酰胺用量 4 % ,二甘醇

单油酸脂 5 % ,合适的乳化工艺 ,硅油 0. 5 % ,适当的其它助剂 ,适用于一切含水体系的消泡 ,尤以中性或碱
性介质效果最好. 其性能与美国 DB11OA 消泡剂相当. 本品已在多家造纸厂使用证明 ,工业品与小、

中试

样品性能一致 ,用户普遍反映良好 ,乐于使用.

Abstract :A synt hetic met hod of new bonding foam - killing agent was p ut forward. The foam supp ressing a

bility and t he foam unstability are t he main p roperties of t he foam - killing agent . The affecting factors were

st udied. Through experiment s , t he chemical composition of t he foam - killing agent was determined. It was

widely used in t he paper indust ry.
