一种非硅乳液消泡剂的配制

The preparation of non-silicon defoamer

将聚醚、混合高级脂肪醇、石蜡、复合乳化剂和助乳化剂复配,制得一种非硅乳液消泡剂。重点探讨不同聚醚、高级脂肪醇、石蜡用量对复配消泡剂消泡和稳定性能的影响。从而找出最佳复配工艺。结果表明高级脂肪醇和石蜡的用量对复配的乳液消泡剂稳定性有着较大影响,而聚醚类型、聚醚和石蜡的用量则对复配的乳液消泡剂消泡性能有着较大影响。最终综合稳定性、消泡性得出较好的配方(聚醚L61:10%,混合高级脂肪醇:8%,液体石蜡:15%)。

Polyether,high fatty alcohol and liquid hydrocarbon was remixed with a wide range of emulsifiers and additives, then a type of non-silicon defoamer was prepared. Studied with respect to the effect of concentration and type of the selected surfactants on the stability and defoaming of emulsions defoamer.Results show that emulsion stability and defoaming was strongly dependent on the types of surfactants used and their Eventually, the stability and good anti-foaming formulation was achieved at Polyether L61 （ 10 wt % ）, remixed High alcohols （8 wt % ）, liquid paraffin （15wt % ）
