无磷助洗剂助洗效率的评价

Evaluation of Washing-aiding Activity of Non-phosphat Auxiliary Detergent

用表面张力法研究了几种洗涤助剂对硬脂酸钠在硬水中的临界胶束浓度（ＣＭＣ）的影响，并以此评价其助洗效率．结果表明，助洗效率按ＮＴＡ（氮川三乙酸）、三聚磷酸钠、聚丙烯酸钠顺序而递减，其中ＮＴＡ和聚丙烯酸钠具有良好的助洗效果，可作为洗涤助剂的主选品种．

The influences of several normal detergents auxiliary agent on the critical micelle concentration(CMC) of sodium stearate in hard water are studied by use of surface tensions The evaluation of their washing aidding activity is also made It is showed experimentally that the reducing order of washing aidding effectiveness is ANT,sodium tripolyphosphat,sodium polyacrylate Among these,ANT and sodium polyacrylate should be taken as main detergent auxiliary agent for their superiority of higher washing aiding activity
