一种新型无磷缓蚀阻垢剂的实验研究
Experimental Study on a Novel Phosphorus-free Corrosion and scale Inhibitor
摘要
Abstract
A novel phosphate-free corrosion and scale inhibitor was obtained from hydrolytic polymaleic anhydride,polyepoxysuccinic acid,sodium gluconate,Sodium and Zinc D-erythorbates.The performance of corrosion and scale inhibition were evaluated by rotary hanging-piece corrosion test,scale inhibition test and electrochemical experiment.The results showed that the dosage of the phosphate-free corrosion and scale inhibitor was 50 mg·L-1,the maximum inhibition and scale inhibition exceeded 90% and 98%,respectively.The phosphate-free corrosion and scale inhibitor mainly inhibits the anode process of corrosion and belongs to mixed-type corrosion and scale inhibitor.And the adsorption of the phosphate-free corrosion and scale inhibitor on A3 metal surface obeys Langmuir adsorption isotherm equation.关键词
