摘要
对木质素磺酸盐(LSs)的理化性能和其作为洗涤助剂的应用潜力进行了研究,讨论了其在洗涤配方中的作用及其机理。实验结果表明:木质素磺酸钠改性产物(GLS)比木质素磺酸钠(LS)具有更好的乳化力、起泡力和钙皂分散力;经过漂白处理后,LS的漂白产物(LSW)白度保持值为91.93%,而GLS的漂白产物(GLSW)白度保持值可达99.37%,基本对标准白布不造成沾污,消除了其对洗涤过程的负面影响;将LS及其改性产物应用于衣物洗涤剂配方中具有明显的增强皮脂去污力特性,为洗涤用品原料的选择提供了一个新的方向。
The properties of lignosulfonates（ LSs） and its potential application as detergent builder were investigated. The mechanism and performance of sodium lignosulfonate（ LS） as well as its modified product（ GLS） in detergent formulations were discussed. The results showed that GLS exhibits better emulsifying power,foaming power and lime soap dispersing power than that of LS. After decolorization,the whiteness retention value of decolorized LS（ LSW） on white swatches achieves 91. 93%,while that of decolorized GLS（ GLSW） achieves 99. 37%. It demonstrated that the decolorizing process could solve the staining problem on white cloth and eliminate the negative effect of LS appears in the laundry process. Blending of LS or its modified product in the laundry detergent exhibits enhanced detergency for sebum soil removal. These results suggested that LS and its modified product may provide a new perspective as a builder for formulation of laundry detergents.
