【摘要】 有机硅消泡剂Fz-890是以二甲基硅油(0.2～3帕·秒)为主体,以多种非离子型表面活性剂为乳化剂,在特定条件下经乳化加工而成的乳状液(O/W型)。它具有消泡性好,乳液稳定,使用成本低等特点。本文介绍其制备工艺的选定、性能测试和在印染、化纤生产中的应用。更多还原

【Abstract】 The FZ-890 organosilicon defoamer is mainly composed of dimethyl silicon oil (200～300 Cps) as principal component, and nonionic surface active agents as the emulsifier under given conditions. The defcamer has characteristics of good defoaming property, stable emulsion and low cost. This article presents the selection of synthesizing technology, determination of its property and some applicable situation about the defoamer used in dyeing and chemical fibre.更多还原
