摘　　要：洗涤助剂是洗涤剂的辅助组分，一般可分为无机盐助剂、有机助剂、溶剂以及其他助剂。它可以使洗涤剂的表面活性剂更好地发挥其对污垢的洗脱、分散、加溶、乳化等作用，提高洗涤效果，并可降低洗涤剂的原材料成本、提高其商业价值。合成洗涤剂除了含有一定量的表面活性剂外．一般都加入一定量的洗涤助剂，以提高洗涤剂的综合能力。因此要使合成洗涤剂具有优良的洗涤性能和较好地适应不同要求的外观。可根据成品的用途要求．在合成洗涤剂中添加一定数量的各种洗涤助剂，使合成洗涤剂的性能更加完备，成本更加低廉。近年来．This article studied the effects of different detergent builders with different concentration to the activity of proteinase in the compound enzyme for bloodstain removing.The research indicated that no significant effect was seen when Na_2SiO_3 and Na_2SO_4 were used with different concentration.The CMC,ISS and Na_2CO_3 could be activated the enzyme to a certain degree when it was used in low concentration,and the affect became weaken when their concentrations increased,however,CMC showed weak inhibitory action.The STPP and 4A zeolite had the weak inhibitory action to the enzyme when their concentrations were 0.4 g/L.Generally speaking,the activity of the proteinase could be kept over 86% when using abovementioned 7 kinds of detergent builders,and they also showed good compatibility performance with proteinase in compound enzyme for bloodstain removing.
