【摘要】 本文研究了无磷洗衣粉的配方，主要以碳酸钠、偏硅酸钠、聚丙烯酸钠、4A沸石、柠檬酸钠、硼研为助洗剂，固定表面活性剂配比，考察上述助洗剂对基础配方去污力的影响，并结合其它因素在本实验范围内筛选出无磷洗衣粉的量佳配方。更多还原

【Abstract】 Some nonphosphate builders such as sodium carbonate,sodium metasilicate,Sodium polyacrylate, 4A Zeo-lite,sodium citrate and borax were incorporated into a basic formula of powder detergent to replace phosphates. The ef-fects of these builders on the detergency were determined. Thus,the better nonphosphate powder detergent with higherdetergency is composed of LAS 14 %,AEO9 2 %,cmc 1 %,Na2CO3 10%,Na2SiO3 %· 5H2O 12%,NaPAA 10%,4A Zeo-lite 25%,Na Citrate 4 % and soap 2% etc.更多还原
