Corrosion Protection Properties of Carbon Fiber Modified Silicates for Grounding Materials in Chlorine-Containing Environments
摘要
Abstract
To improve the corrosion protection performance of grounding materials of power facilities and further enhance the reliability of power equipment,a carbon fiber modified silicate grounding material with low resistivity and excellent anti-corrosion performance was developed,and its electrical conductiv-ity and anti-corrosion performance were tested and characterized by conductivity test and immersion test.The results show that the carbon fiber content is 0.25(weight percentage,same below),the resistiv-ity of the modified silicate material is 0.685 Ω·m.With the increasing of the carbon fiber addition con-tent(1.27),the resistivity of the modified silicate material decreases to 0.069 Ω·m.Moreover,as the carbon fiber addition content increases,the fluctuation of the resistivity of the modified silicate material decreases significantly reduced.Under the condition of NaCl solution and 6 V bias voltage,the corrosion rate of the grounding material coated by modified silicate from small to large is stainless steel＜copper＜Q235＜galvanized steel.Further through the soil burying test,it is found that the corrosion rate of the Q235 sample is significantly reduced after they are coated by the modified silicate material.关键词
