摘要
为了提高硫酸钡垢的防垢效率,明确防垢剂的作用机理,以马来酸酐、丙烯酸和新型酯类单体为主要原料,合成了一种新型硫酸钡垢防垢剂HFGJ-26,考察了防垢剂浓度、成垢离子浓度以及实验温度对防垢效果的影响,并在此基础之上,研究了防垢剂的作用机理.实验结果表明,新型硫酸钡垢防垢剂HFGJ-26 对溶液中BaSO4 的防垢效果较好,当水溶液中的Ba2+和SO42-的浓度均为 300mg·L-1 时,添加 100mg·L-1 的防垢剂HFGJ-26 即可达到较高的防垢率,实验温度为 60℃时,防垢率可以达到 97.8%,而当温度升高至 100℃时,防垢率仍能达到 92.6%,防垢效果较好.
Abstract
In order to improve the anti-scaling efficiency of barium sulfate scale and clarify the mechanism of action of the anti-scaling agent,a new type of barium sulfate scale inhibitor HFGJ-26 was synthesized using maleic anhydride,acrylic acid,and new ester monomers as the main raw materials.The effects of anti-scaling agent concentration,scaling ion concentration,and experimental temperature on the anti-scaling effect were investigated,and on this basis,the mechanism of action of the anti-scaling agent was studied.The results show that the new barium sulfate scale inhibitor HFGJ-26 has a good anti scaling effect on barium sulfate in solution.When the concentrations of Ba2+ and SO42-in the aqueous solution are both 300mg·L-1,adding 100mg·L-1 of HFGJ-26 can achieve a higher anti-scaling rate.At an experimental temperature of 60℃,the anti-scaling rate can reach 97.8%,while when the temperature rises to 100℃,the anti-scaling rate can still reach 92.6%,indicating a good anti-scaling effect.
