ＴＪ－２０１是一种含马来酸基、磷酸亚基、氧乙烯在等的膦基聚羧酸，用失重法研究了ＴＪ－２０１对２０＃碳钢的缓蚀性能讨论了与Ｚｎ＾２＋复配后的缓蚀作用以及温度、ＰＨ值、转速、时间对缓蚀性能的影响，结果表明，用现场水质、不预膜、投加量６ｍＬ（以ＰＯ４＾３－计为０．８ｍｇ／Ｌ）时缓蚀率为９９．１％；该药剂可在较宽ＰＨ值（６￣１２）和温度（２０￣８０℃）人使用；在一定的流速下具有优异的缓蚀性能和良好的热稳定
Agent TJ-201 is an organic phosphonocarboxylic acid containing maleic group, phosphonic group, and ethoxyl group etc. Rotary coupon test was used to study the corrosion inhibitive performance of TJ-201 for mild steel. The results showed that TJ-201 and Zn( II ) have obviously synergetic effect and the inhibitive performance is influenced by factors such as pH , temperature, rotation speed ,time and so on. The corrosion inhibition rate (no pretreatment) is 99.1% in the field water (normal running concentration: 6 mg/L) and 98.9 % in the compounding water (normal running concentration: 14 mg/L). The agent can be used well at pH 6-12 and temperature from 20 to 80C . It has an excellent performance in corrosion inhibition and heat stability at the proper rotation speed.
