摘要: 采用微生物方法研究了硫酸盐还原菌(SRB)在不同磁感应强度下的生长情况,利用失重法计算了不同磁感应强度下X100钢在含有SRB的土壤模拟溶液中的腐蚀速率。研究发现,磁场可以抑制SRB的生长,且磁感应强度越强抑制作用越大;磁场可以抑制X100钢的微生物腐蚀速率,腐蚀速率随磁感应强度的增加呈先减小后增大的态势;磁感应强度为5mT时,腐蚀速率最小。简述了静磁场对微生物存活率和金属腐蚀速率的影响,并提出了利用磁场抑制管道微生物腐蚀的新设想。

Abstract:

The growth of sulfate reducing bacteria (SRB) under different magnetic field strength was studied by using microbial method. The corrosion rate of X100 steel in simulated solution of SRB steel under different magnetic field strength was calculated by the method of weight loss. It was found that the magnetic field could inhibit the growth of SRB, and the stronger the magnetic field intensity was, the stronger the inhibition effect was; The magnetic field could inhibit the corrosion rate of X100 steel, and the corrosion rate of X100 steel first decreased and then increased with the increase of magnetic field strength. When the magnetic field strength was 5 mT, the corrosion rate was the smallest. The influence of static magnetic field on the survival rate of microbe and the corrosion rate of metals were briefly introduced. A new idea for the inhibition of microbial corrosion in pipeline was proposed.

Key words: Static magnetic field, Pipeline, Microbe, Weight loss method, Corrosion rate
