VCI is the abbreviation of gas phase corrosion inhibitor, and the anti-rust bag is actually made of anti-rust film through heat sealing process, so the anti-rust principle of anti-rust bag can be directly explained by the anti-rust principle of anti-rust film. The anti-rust film is made by mixing VCI anti-rust masterbatch and PE masterbatch, so that the VCI corrosion inhibitor is evenly distributed on the surface of the film and can be continuously volatilized. According to the structure, it can be divided into double-layer single Surface, three-layer double-sided two kinds, when the anti-rust film wraps or contains the metal, a closed space is formed, the continuous volatilization of VCI forms saturation, and the VCI molecules continue to adsorb on the metal surface to form several molecular protective layers. Passivating metals while blocking oxygen and moisture is the basic principle of rust prevention. The anti-rust products developed and produced by our company mainly include VCI vapor phase anti-rust paper, anti-rust film (bag) and other vaporized anti-rust products. We have rich anti-rust experience and superb anti-rust technology. We can design personalized anti-rust solutions according to the specific requirements of customers and the performance of anti-rust products to help customers choose economical and suitable anti-rust products and solutions. The customers we serve include General Electric and Nipiao from Japan.
