| Abstract: | In view of such characteristics as moist soil,high underground water level,high concentration of chlorion and sulfate ion,various microbions,abundant vegetation and many roots and rhizomas,etc.in Zigong and its nearby regions,Sichuan Province,a lot of experimental and research works for selecting the corrosion protecting coating for the external wall of both new and old buried tanks are conducted and the coating and corollary paint for treating the residual asphalt on the buried pipeline and oil tank are developed.Through their use in practice,it is shown that the paint has following advantages:good adhesive force,strong ability to resist water,chemical media and microbial corrosion and easy operation,etc.,being an ideal corrosion protecting coating for the external wall of buried metalic storage tank. |
