天然高分子改性多功能水处理剂FIQ-C缓蚀性能及缓蚀机理的研究

Study on Corrosion Inhibitive Performance and Mechanism of Natural Polymer Mutifuctional Water Treatment Agent FIQ C

研究了多功能水处理剂 FIQ- C在循环冷却水中对 A3钢的缓蚀性能 ,考察了各种因素对缓蚀性能的影响 ,探讨了 FIQ- C的缓蚀机理。研究结果表明 ,当 FIQ- C的投加量为 5 mg/ L时 ,在循环冷却水中的缓蚀率可达 6 0 %以上 ,且在中、低温条件下对 A3钢均具有良好的缓蚀作用 。

In this paper the corrosion inhibitive performance of mutifunctional water treatment agent FIQ C for mild steel was studied.Factors affecting the corrosion inhibition were investigated and the corrosion inhibitive mechanism of FIQ C was discussed.Results showed that the corrosion inhibition rate is up to 60% in cool recycle water (normal running concentration:5mg/L).The agent can be used well at temperature from 20 to 40℃ and it was a mixing-type inhibitor.
