Study on the Volatile Corrosion Inhibitor for Protection of Electrical Equipment in Island Environment
According to the protection requirements of electrical equipment in island environment,8 kinds of volatile corrosion inhibitors were selected and investigated.The protection performance of volatile corrosion inhibitors was evaluated through volatilizing loss test,gas phase corrosion inhibition test,electrochemical test and salt spray test.The results of volatilizing loss test show that CORTEC VPCI-609,RTFD VCI,and SF/D-331 have both high and low volatile components,and have volatilization persistence.The gas phase corrosion inhibition test results show that RTFD VCI and VCIrus-505 VCI P have about corrosion inhibition on the four metals.The electrochemical results show that RTFD VCI and SF/D-331 have positive corrosion inhibition effect on the four metals.The salt spray test shows that RTFD VCI and SF/D-331 have a long-term protective effect on the computer mainboard,and have no effect on its electrical performance.In summary,RTFD VCI and SF/D-331 have positive protection for four kinds of metals(copper,aluminum,steel,magnesium),and have better protective effect on the computer mainboard,and do not affect its electrical performance,suitable for the rust prevention of electrical equipment,various components and various metal parts.
