摘　　要：δ-层状结晶二硅酸钠以其优良的助洗性能被称为新一代无磷助洗剂。介绍了δ-层硅的结构特点及其助洗机理,详细阐述了其优良的助洗性能和特点,探讨了δ-层硅的溶解性、储存稳定性以及是否存在硅酸盐沉淀等模糊概念,认为δ-层硅助洗剂作为一种产品和商品已经具备了大力发展的条件。δ-crystalline layered sodium disilicate is regarded as a new generation non-phosphate detergent builder for its good washing ability. This paper introduces the structure and bivalent ion binding mechanism of δ-crystaIline layered disilicate. It expatiates on the good properties of δ-crystalline layered disilicate as a detergent builder in detail. And some doubtful questions are discussed such as dissolubility, stability and deposition. It indicates that the δ- crystalline layered disilicate has had the qualification for developing energetically as a kind of production or merchandise.
