摘要
以两种高价金属盐(M2+/W3+)为引发剂,使马来酸酐和棉纤维进行接枝共聚,研究了马来酸酐的初始浓度和反应温度对接枝反应的影响;同时研究了改性后的纤维在循环冷却系统中的防垢作用。试验结果表明,马来酸酐在初始质量分数为40%,反应温度为100℃的条件下进行接枝反应能得到较高的接枝效率;改性纤维对水中钙、镁离子的吸附作用和增溶作用防止了水垢的生成。
Graft co-polymerization of ammonium maleic anhydride onto cotton fibre was studied using two kinds of multi-valence metal compounds as catalyst. The effect of initial maleic anhydride concentration and reaction temperature on the graft co-polymerization was investigated. It was found that when the monomer concentration was 40% and the reaction temperature was 100℃, the copolymerization exhibited high grafting efficiency. The grafted fibre was used as antiscaling agent in a simulated industry cooling water system to observe its ion exchange and adsorption characteristics. The test results showed that the formation of scale in said cooling water system was reduced due to the adsorption of calcium and magnesium cations and the increase of these cations solubility by grafted fibre.
