脂肪酸甲酯乙氧基化物FMEE及其磺酸盐FMES在羽绒清洗中的应用

The Application of Fatty Acid Methyl Ester Ethoxylates FMEE and FMES in the Washing Process for Feather

在羽绒洗涤过程中表面活性剂具有很重要的作用,PO嵌段脂肪酸甲酯乙氧基化物(FMEE)及其磺酸盐(FMES)泡沫低,低温条件下的脱脂力强,并具有显著的防止污垢二次沉积效果,洗涤后的羽绒白度高,色泽光亮,适用于羽毛羽绒的清洗加工工艺。为了得到清洗力强、无磷环保的洗涤剂,通过正交实验确定羽绒清洗剂配方为:PO嵌段FMEE 8%、FMES 8%、无磷乙二胺二邻苯基乙酸钠(EDDHA-Na)2%、伯烷基磺酸钠(PAS)6%、蓖麻油聚氧乙烯醚(EL-40)4%、纯净水72%,将该配方应用于羽绒清洗生产工艺,残脂率、浊度、耗氧量、白度等指标均优于现用清洗剂。

Surfactant plays an important role in the washing process.The PO blocked fatty acid methyl ester ethoxylates(FMEE)and FMES have low-foaming and high-washing ability,which have the remarkable effect of antideposition of dirt,so the whiteness of the washed feather is high.In order to get the no-phosphorus feather detergent with strong cleaning power,the formulation of feather cleaning agent was determined by orthogonal test as follows:Po blocked FMEE 8%,FMES 8%,phosphorus free EDDHA-Na 2%,primary alkyl sulfonate sodium(PAS)6%,EL-404%,purified water 72%,the residual fat rate,turbidity,oxygen consumption and whiteness of the formulation are better than the current cleaning agent.
