浅析常用降阻剂的性能及应用

摘要

With the rapid economic development,to safeguard people＇s lives and properties,the demand of protection against lightning for people is increasing.Resistance reducing agent has a good capacity of water absorption and water retention and plays an important role in against lightning,which can reduce electrical resistivity of soil,increase the effective cross section of grounding electrodes,eliminate contact resistance.But it also has many disadvantages,such as eroding grounding electrodes,polluting groundwater and instability.Therefore,when using resistance reducing agent in against lightning,the electrical conductivity,causticity,stability,long residual action should be considered to maximize its efficacy.%随着经济的快速发展,为了更好地保障人民生命财产安全,国家对防雷减灾的要求越来越高。降阻剂是一种常用防雷产品,在防雷减灾方面起到重要的作用,可以有效降低土壤电阻率、增大接地体的有效截面、消除接触电阻、具有良好的吸水性和保水性,但降阻剂在使用过程中存在对接地体的腐蚀、稳定性较差、产生地下水污染等问题。所以在使用降阻剂时,应充分考虑其电阻率、腐蚀性、稳定性、长效性、对环境无污染等因素,将其功效发挥到最大。
