摘要
XL-Ⅱ是在木质素分子链上引入羧基、胺在和磺酸基的新型泥浆降粘剂。其降粘作用和抗盐、抗钙能力都优于铁铬木质素磺酸盐，同时消除了铬对环境的污染。对XL-Ⅱ的降粘机理也进行了初步分析。
XL-Ⅱ is modified lignosulfonate which carboxylic, amino and sulfonic group are linked in the lignosulfonate molecular chain. Its thinning effect, salt and calcium resistance is better than ferrochrome lignosulf onate, but no chromium pollution. A preliminary analyse of thinning mechanism of XL-Ⅱ is also given.
