Water-dispersible defoamer composition |
摘要 |
Water-dispersible defoamer compositions comprise an intimate blend of a mixture of defoaming components and at least one emulsifier to impart water-dispersibility to the composition. The defoaming components include a monoester of an alkenylated succinic acid, a particular organo-phosphorus compound and a silicone oil. The defoamer compositions have particular use in pulp mill defoaming compositions.
