Why does metal rust?
Generally, the reason for metal rust is explained by the electrochemical theory.
After the moisture (electrolyte) is formed on the metal surface, the electron energy of the metal naturally flows and then flows back to the high-energy region of the metal (cathode).
In the energy zone, such a continuous cycle produces metal to rust and corrosion.
Vapor phase corrosion inhibitor (VCI), effective anti-rust, and anti-corrosion.
VCI is a volatile chemical ion. When all kinds of metals are packaged in this product, the vaporized positive and negative ions will be dispersed with the air, and they will mutually adsorb with the positive and negative electrons on the surface of various metals, forming 3-5.
Molecular protective film, the protective layer can prevent the corrosion and oxidation of moisture, salt, acid, and alkaline substances, and polluting deposits so that all kinds of metals (iron and non-iron) can achieve rust and corrosion resistance.
VCI technology is a comprehensive technology integrating organic synthesis, physical chemistry, corrosion and protection, metal materials, paper processing, and polymer technologies.
Different VCI systems have big differences in safety, high efficiency, environmental protection, and applicability, so they are embodied in products of various forms and functions.
The unique formula of vapor phase rust prevention has both rust prevention and packaging effects.
VCI products contain a uniquely developed formula, which can quickly volatilize effective substances and reduce water activity, thereby achieving the effect of inhibiting corrosion. Has the following advantages:
1. It has good rust resistance, which can protect the product for more than 2 years on average.
2. It has dual functions of rust prevention and packaging, no application, degreasing, cleaning, and other procedures, saving labor, time, and cost.
3. After packaging, it quickly exerts the anti-rust function, even for items with irregular surfaces, it can prevent corrosion in all directions without leaving any dead spots.
4. Simple and convenient to use, improve packaging efficiency, and reduce packaging costs.
5. Environmental protection and safety, wide application range.
