以天然高分子植物胶粉F691为原料,经过改性后,制得具有絮凝、缓蚀、杀菌等多种功能的水处理药剂FIQ—C。研究了各种因素对合成的影响,并设计正交实验找出了最佳反应条件。结果表明,当反应温度为 50℃,反应时间为 2h,氢氧化钠投加量 (按胶粉量 )为 0.4g/g,投料比为 1 6时,制成的药剂相对粘度>3.0 (0.5 % ),阳离子取代度可达 55 %以上,高分子的结构经红外光谱得到确证。且FIQ—C具有良好的絮凝、缓蚀、杀菌性能。

The multifunction w ater treatment reagent FIQ -C has been synthesized through chemical modification with the natural polymer F₆₉₁ powder.Factors af fecting the preperation are studied and the best reaction conditions are found by the optimizat ion experiment s.Experimental result s show :the relative viscosi ty is up to 3.1 (0.5 %)and the density of cationic quaternary ammonium g roup is up to 55 %w hen the reaction temperature is 50 ℃, the reaction time is two hours, NaOH (to F691)is 0.4 g/g and the feeding ratio of the raw material is 1.6.The structures of polymers are characterized by FTIR method.FIQ -C had good efficiency of f locculation, corrosion inhibition and scal inhibition.
