Vapor-phase anti-rust paper is a new type of anti-rust packaging material made by coating the anti-rust base paper with vapor-phase corrosion inhibitor. Gas phase corrosion inhibitor is a kind of corrosion inhibitor prepared by special synthesis technology.

The antirust liquid can be directly vaporized at room temperature and pressure by itself or attached to a suitable carrier. Any space gap in the unit is filled with a mixture of gases containing the VCI anti-rust factor, which absorbs the metal surface when it encounters it, forming a dense protective film layer only one or a few molecules thick. The protective film layer can effectively isolate the contact between the metal surface and water, oxygen and other harmful atmospheric corrosion factors, and inhibit the occurrence of electrochemical reactions that promote metal corrosion, so as to achieve the best anti-rust effect.
