Abstract

This study investigated the metal surface protection ability of a preservation technology combining a volatile corrosion inhibitor (VCI) with PE film packaging and vacuum sealing. The evaluation was conducted using both natural exposure tests and modern laboratory equipment at the Institute of Chemistry and Materials. The results showed that a small amount of VCI can effectively protect metal surfaces from corrosion. After being exposed to a corrosive environment, the CT3 steel sample protected by the preservation process showed a protection efficiency of 30.49%, while the red copper sample showed an efficiency of 45.91%. According to the salt spray and temperature-humidity test results, the surfaces of CT3 steel, red copper, and yellow copper samples showed no discoloration, stains, or rust spots after being packaged using the above preservation process.
