Abstract: Resistance reducing agents are liable reducing agent
to corrode the covered metal earthing material to a
Key words: earth-termination system; corrosion
certain extent, so the corrosivity of the resistance rate; resistance reducing agent; weight-loss method
reducing agent must comply with relevant standards. outdoor test; indoor test; electrochemical test; metal
At present, the corrosivity of the resistance reducing corrosion test
agent is usually tested by the weight-loss method
which comprises two test procedures, i. e. indoor
摘要:降阻剂对其包東的金属接地材料会造
corrosion test and outdoor corrosion test.The成一定程度的腐蚀,因此降胆剂的腐蚀性必须待合
resistance reducing agent is judged to be qualified or相关标准的规定。目前通常采用失重法测试降阻剂
not through computing the corrosion rate of the的腐蚀性,利用失重法测试降阻剂腐蚀性包含两个
resistance reducing agent according to the weight试验过程,一是室内腐蚀试验,二是野外腐蚀试验。
change of the sample before and after the test.The通过试验前后试样的重量变化计算降阻荆的腐蚀速
result of the corrosion test on a branded resistance率,用以判定降阻剂是否合格。用失重法对某品牌
reducing agent by the weight- loss method indicates降沮剂进行腐蚀试验涮试,结果表明该品牌降阻剂
that the corrosivity of the tested resistance reducing腐蚀性不符合相关标准要求。失重法等传统试验存
