The preparation and IR properties of 1 butylamine, dimethylamine, trimethylamine, triethylamine, benzylamine, 4 methylaniline and 4 aminobenzenesulfonic acid modified glutaraldehyde crosslinked chitosan activated with cyanuric chloride were studied. 研究了以三聚氯氰为活化剂,正丁胺、二甲胺、三甲胺、三乙胺、苯甲胺、对甲基苯胺、对氨基苯磺酸修饰戊二醛交联壳聚糖的制备及其红外光谱。
Aminobenzenesulfonic acid super-plasticizer is selected though cement paste test, which be provided with high water-reducing property, low slump loss and good compatibility with cement. 通过水泥净浆试验比较选择了减水率高、坍落度损失小、与水泥适应性好的氨基苯磺酸盐高效减水剂;
