接地网或埋地管线等金属设施腐蚀原因有 :腐蚀电池导致的腐蚀 ,外在电流源导致的腐蚀 ,以及土壤结构、性质 ,溶液的运动速度和酸、碱浓度等都会对腐蚀程度构成影响。其防止腐蚀的措施有 :牺牲阳极保护法、外加电源阴极保护法、在电极周围填焦炭粉和绝缘隔离等方法。 Grounding or buried pipelines and other metal facilities due to corrosion: corrosion caused by corrosion of the battery, the external current source caused by corrosion, as well as the soil structure, nature, speed of the solution and acid, alkali concentration will have an impact on the degree of corrosion. The measures to prevent corrosion include: sacrificial anode protection method, plus power cathodic protection method, in the electrode around the coke powder and insulation insulation and other methods.
