Technical field
The present invention relates to Lightning protection, espespecially a kind of reduce method and the grounded resistance reducing agent thereof that grounding body is corroded by grounded resistance reducing agent.
Background technology
Earthed system is the important step of whole lightning-protection system, and sky net and earth mat are coupled together by it, the overall earial drainage rate improving grounded screen. The key technical indexes of lightning protection earthing system is earth resistance, and earth resistance is the smaller the better. In order to reduce earth resistance, generally use friction reducer. The function of friction reducer is exactly the earth resistance for reducing various grounding device. At present, friction reducer is made up of multiple components, as wherein contained fine graphite, bentonite, firming agent, lubricant, electroconductive cement etc., thus becoming a kind of good electric conductor. It is used between metallic ground body and soil, can be in close contact with metallic ground body on the one hand, form sufficiently large current flowing face; On the other hand it can soil permeability towards periphery, reduce surrounding soil resistivity, around grounding body, form a mild low resistance region of change.
But, due to also conductive strong salinity (silicate, aluminosilicate etc.) in friction reducer, the corrosivity of metallic ground body is relatively big, and the time is more long, and the corrosivity of metallic ground body is continuously increased.The electric conductivity causing metallic ground body constantly reduces, and lightning protection effect declines. In order to avoid lightning strike accident, it is necessary to reinstall, again constructing, human and material resources, financial resources consumption are big. Currently used friction reducer only considers the resistance reducing effect constructed in a short time, does not consider its chronicity, long-lasting, the feature of environmental protection.
Market demand is a kind of reduces the method that grounding body is corroded by grounded resistance reducing agent, thus obtaining a kind of environmental friendly, anti-corrosive long-lasting grounding friction reducer, causes the corrosion improved metallic ground body, and antiseptic effect improves, and grounding body is greatly prolonged service life.
