TJ 2 0 1是一种含马来酸基、磷酸亚基、氧乙烯基等的膦基聚羧酸 .用失重法研究了TJ 2 0 1对 2 0 # 碳钢的缓蚀性能 .讨论了与Zn2 + 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 6mg L(以PO3 -4计为 0 .8mg L)时缓蚀率为 99.1 % ;该药剂可在较宽pH值 (6～ 1 2 )和温度 (2 0～ 80℃ )范围内使用 ;在一定的流速下具有优异的缓蚀性能和良好的热稳定性 TJ 2 0 1 is a phosphonic polycarboxylic acid containing maleic acid, phosphoric acid subunit, oxyethylene, etc. The corrosion inhibition of TJ 2 0 1 to 20 # carbon steel was studied by weight loss method With Zn2 + and the effect of temperature, pH value, rotation speed and time on the corrosion inhibition performance.The results show that with the on-site water quality, without pre-membrane, dosage 6mg L .8mg L), the corrosion inhibition rate is 99.1%; the agent can be used in a wide range of pH (6 ~ 12) and temperature (20 ~ 80 ℃); has excellent corrosion inhibition performance And good thermal stability
