摘要/Abstract

摘要：

焦家金矿井下水氯离子含量4 000～6 000mg/ L ,金属管材、道轨长期处在潮湿的井下,当金属与井下水接触时,形成原电池而引起金属管道的电化学腐蚀。鉴于金属的电化学腐蚀是阳极(活泼金属) 被腐蚀,可以借助于外加阳极(更活泼的金属或直流电源)将井下的管道、道轨作为阴极保护起来。采用牺牲阳极保护技术来预防井下金属管道腐蚀,阳极材料使用镁合金,被保护金属管道的电极电位控制在- 0. 88～- 1. 22V 之间,对井下金属设施起到了很好的保护作用。

Abstract:

In the J iaojia Gold Mine , the concent ration of chlorin ion is about 4 000～6 000 mg/ L. The metal-material pipes and t racks are in the moist well , and when the metal meet s the water in the well , the galvanicbattery is formed and the metalpipe is eroded. Because the metal elect rochemist ry eroding is originated f rom the anode of metal , the metal-material pipes and t racks can be protected as the cathode by adding anode. The technique required that the material anode is magnesium-alloy and the elect rode-voltage of protected metal pipes is cont rolled under 1. 22V～0.88V. And metal installations can be protected under well efficiently by this technique.

Key words: metal-material pipes under well, abandon-anode-protection technique, anode materials, magnesium-alloy, elect rode-voltage
