AQUEOUS DEFOAMER DISPERSIONS OF ETHYLENEBIS (STEARAMIDE) |
摘要 |
Aqueous substantially hydrocarbon oil-free emulsions prepared from aliphatic diamides, such as ethylenebis (stearamide) (EBS) and related compounds, are found to be effective defoamers for use in various paper-making operations. These compositions avoid many of the deleterious effects of conventional oil-based EBS defoamers, thereby allowing their use on paper machines. |
