摘要
为提高聚丙烯酸盐类高分子水处理剂的功能,特别是加强阻垢效果,在对丙烯酸(AA)/丙烯酰胺(AM)共聚物中加入络合剂,采用模拟蒸发试验对其阻垢效果进行研究,结果表明:加入添加有EDTA-2Na、酒石酸(TA)或柠檬酸(CA)络合剂的AA/AM共聚物0.02 mL/L,阻垢率可达97%～98%,与不加络合剂的AA/AM共聚物比较,阻垢率提高了约10%。
In order to improve the function of the polyacrylate macromolecular water treatment agent,especially to strengthen its scale inhibition effect,complexing agents were added into acrylic acid（AA）/acrylamide（AM） copolymer,the effects of them on scale inhibition were studied through the simulant evaporation experiment.The results showed that： adding 0.02 mL/L of copolymer which containing complexing agents including EDTA-2Na,tartaric acie（TA）,citric acid（CA）,the scale inhibition rate reached 97%-98%,which was about 10% higher than that adding AA/AM copolymer containing no complexing agent.
