亲水疏水平衡值对有机硅消泡剂性能的影响
首发时间:2010-08-25
摘要:有机硅消泡剂以其优异的性能广泛应用于工业生产中,有机硅消泡剂以二甲基硅油和白炭黑组成的硅膏为主体成分,添加司盘80和吐温80调制亲水疏水平衡值后加热搅拌制得高稳定性的有机硅消泡剂,在消泡剂中乳化剂的亲水疏水平衡值不同对消泡剂性能有很大的影响。在有机硅消泡剂中,保持有机硅消泡剂中其它有效物质的成分及组成不变,在相同的制备条件下添加不同亲水疏水平衡值的乳化剂,依据有机硅消泡剂性能中消泡性能和稳定性为检测条件,研究出有机硅消泡剂最适宜的亲水疏水平衡值。

The value of Hydrophile-lipophile Balance number effect on the performance of organic silicone defoamer
Abstract:The organic silicone defoamer is widely used in industrial production due to its superior performance. In this paper, organic silicon defoamer is prepared by using dimethylsilieone and silicon dioxide as the main material. Add span80 and tween80 modulation the value of theHydrophile-Lipophile Balance Number,heating and stiring the mixing of the organic silicone defoamer.Finally, in defoaming agent of silica , the value of emulsifier′s Hydrophile-Lipophile Balance Number has a great performance of the organic silicone defoamer. In organic silicone defoamer, keep the other effective ingredients and composition of the substance of the silicone defoamer invariant, in the same preparation conditions , added different Hydrophile-Lipophile Balance Number value of emulsifiers to the organic silicone defoamer , according to the properties of disinfection bubble performance and stability for testing conditions of the organic silicone defoamer , study the optimum Hydrophile-Lipophile Balance Number value of the organic silicone defoamer.
Keywords: Hydrophile-Lipophile Balance Number organic silico defoaming agent
