Automotive parts are prone to corrosion from moisture and oxygen during production, transportation, and storage, which seriously affects their performance and appearance. To effectively prevent corrosion, the traditional method is to spray or apply lubricating oil and other oil-based rust inhibitors on the surface of the parts. However, the disadvantages of this method have gradually become apparent.
1. Complex operation and easy secondary pollution: Applying oil-based rust inhibitors requires spraying or applying rust inhibitors, which not only complicates the operation but also easily pollutes equipment and the environment.
2. Not conducive to subsequent processing: Parts with oil-based rust inhibitors are not conducive to subsequent operations such as painting and welding and require degreasing treatment, increasing processes and costs.
3. Limited rust prevention effect: The rust prevention effect of oil-based rust inhibitors depends on the integrity of the oil film, but the oil film is easily damaged, leading to poor rust prevention.
4. Affects product appearance: Oil-based rust inhibitors are prone to form oil stains on the surface of products, affecting the appearance quality and aesthetics of products.
VCI oil-free rust-proof packaging suppresses metal surface corrosion by adsorbing and neutralizing corrosive gases in the air and has the following advantages
1. No need for frequent replacement and coating, which greatly reduces material procurement costs. Traditional rust prevention oil requires regular replacement and supplementation, resulting in higher material costs.
2. Compared with traditional rust prevention oil, VCI oil-free rust-proof packaging does not require downtime for cleaning and coating rust inhibitors, simplifies processes, and improves production efficiency.
3. No need for complex wastewater treatment, while the waste and wastewater generated by traditional rust prevention oil require professional treatment.
4. Has a long-term rust prevention effect and can extend the service life of workpieces.
5. Does not form a thick oil film or change the appearance of the surface, maintaining the beauty and quality of the product.
Therefore, VCI oil-free rust-proof packaging is an ideal choice for protecting automotive parts from rust. It is simple to operate, pollution-free, does not affect subsequent processes, has good rust prevention effects and product appearance, and can effectively meet the rust prevention needs of automotive parts during production and transportation.
VCI rust inhibitors are coated on high-quality imported raw paper, and during use, they continuously release a small amount of VCI rust inhibitor, which forms a rust-proof and corrosion-inhibiting protective layer on the metal surface, effectively alleviating metal corrosion. It has the advantages of safety and environmental protection, convenience and cost reduction, and no cleaning required, making it more suitable for rust prevention in the intermediate process of product production and circulation.
VCI + rust-proof film uses unique volatile corrosion inhibitors (VCI) technology, which can release rust inhibitors in the packaging material to form a protective gas phase layer that covers and protects the metal surface. This film can effectively prevent the invasion of oxygen and moisture, and extend the rust prevention life of metal products. It has the advantages
3. VCI water-based rust inhibitor
specially developed for oil-free rust prevention of metal workpieces, it adds VCI gas-phase corrosion inhibitors. When VCI molecules evaporate into a closed space, a dense protective film is formed on the metal surface, thereby providing better protection to the metal. The rust prevention and salt spray resistance of the treated workpiece are significantly enhanced, and the surface is oil-free, allowing for direct unpacking and use, and can completely replace mineral rust prevention oil. It has the advantages of excellent rust prevention performance, good adhesion, safety and environmental protection.
