一种环保型无磷阻垢缓蚀剂的研制

Development of an Environmentally Friendly Phosphorus-free Scale and Corrosion Inhibitor

采用天然类多糖甲壳素的衍生物壳聚糖和聚环氧琥珀酸(PESA)等复配得到一种新型的无磷阻垢缓蚀剂,其处理效果较市售产品阻垢率提高20.67%,且用量仅为原来的53.33%,药剂成本下降20%,并通过正交试验确定壳聚糖的最佳阻垢条件。无论是从性价比还是环保性能等方面均优于传统的磷系阻垢缓蚀剂,具有明显的经济与环境效益。

The natural polysaccharide chitin chitosan derivatives and compound of polyepoxysuccinic acid（ PESA） and get a new non phosphorus scale inhibitor and corrosion inhibitor,the treatment effect is commercially available products scale inhibition rate increased 20. 67%,and the amount is only original 53. 33%,reagent cost decreased by 20% and orthogonal test to determine the optimal scale and condition of chitosan. Whether from the cost or the environmental protection performance and other aspects are better than the traditional phosphorus scale inhibitor and corrosion inhibitor,with obvious economic and environmental benefits.
