摘　　要：目前工业上大量使用的无磷洗涤助剂为 4A沸石和偏硅酸钠 ,4A存在潜在的铝污染问题 ,而偏硅酸钠的抗硬水性差 .新型无磷洗涤助剂的研究围绕着提高碱金属硅酸盐的抗硬水能力展开 ,一是制备结晶层状二硅酸钠 ,二是将硅酸钠与其它助剂复合制备复合洗涤助剂 .全面介绍了国内外无磷洗涤助剂的研究进展情况 ,并指出 ,自主开发性能优良、价格适中的复合无磷洗剂助剂 。Zeolite(4A) and sodium metasilicates are largely used as phosphate-free detergent builders in industry. There is a potential pollution because of the zeolite containing Al 3+ .The softening water capability of sodium metasilicate is poor. New phosphate-free detergent builders are developed in order to increase softening water capability of alkali silicates. One way is the manufacturing of crystalline layered sodium disilicates, and the other is that of the manufacture of composite detergent builders. The industrial producting situation, research progress and development tendency in the phosphafe-free detergent builders are fully introduced in this paper.
