Currently, vapor phase corrosion prevention materials and technologies are extensively applied abroad in the rust and corrosion treatment of industrial equipment. Particularly in recent years, with the rise of the information industry, vapor phase corrosion prevention technology has shown unique advantages in the packaging processing of IT and electronic products.

The Principle of Vapour Phase Rust Inhibition:

Vapor phase corrosion inhibitors work by releasing a protective vapor when immersed in the material. These inhibitors slowly volatilize at room temperature, creating a stable protective film on the exposed metal surface, typically just one to two molecules thick. This film effectively prevents corrosion caused by oxygen and moisture in the environment, providing excellent rust prevention. The continuous volatilization of the inhibitor molecules maintains a saturated state within enclosed spaces, ensuring long-lasting and stable rust protection. Moreover, as the inhibitor molecules are in a gaseous state, they penetrate all crevices, regardless of the complexity of the metal product's shape, delivering ideal rust prevention.

This new anti-corrosion mechanism boasts numerous unparalleled advantages when compared to traditional methods. After the packaging or coating of metal materials is completed, the molecules of the gaseous corrosion inhibitor begin to disperse.

Vapor phase corrosion inhibitors can penetrate into crevices that traditional rust preventive oils cannot reach, ensuring rust prevention without any blind spots. Moreover, they offer waterproof, moisture-resistant, oil-resistant, and chemical-resistant properties.

VCI stands for Volatile Corrosion Inhibitor, a corrosion inhibitor synthesized through a special formulation and compound preparation process.

It can vaporize directly at room temperature and pressure, either independently or attached to a suitable carrier.

In a sealed environment, any space gaps within the operating unit are filled with a mixture of gas containing VCI corrosion inhibitors, which, upon encountering metal surfaces, adhere to them and form a dense protective film layer with a thickness of only one or several molecules.

This protective film effectively isolates the metal surface from contact with moisture, oxygen, and other harmful atmospheric corrosive factors, inhibiting the electrochemical reactions that promote metal corrosion, thereby achieving a good anti-corrosion effect.
