Rust preventive packaging solutions, VCI rust preventive bags, and rust preventive paper products are commonly used rust prevention products. In rust preventive packaging and protection, they play a vital role in protecting metal products from rust. For rust preventive packaging materials that we are more familiar with and use more often, some people may be more realistic. Researching two products, what are the effects? Now let's study and analyze whether rust preventive bags or VCI rust preventive paper is better.
The meteorological rust preventive film (bag) series products mix LDPE resin and VCI masterbatch according to the standard process and production parameters, and then produce dry film. Widely used in various industries such as auto parts, military industry, machinery, home appliances, and electrical engineering. This product has the characteristics of transparency, intuitive barrier properties, rust prevention period, and ease of use, and is a new generation of economical, affordable, and environmentally friendly rust preventive packaging materials.
Multi-metal vapor phase rust preventive paper is a new type of rust preventive packaging material synthesized using rust preventive paper base paper and multi-layer resin materials as the base material and coated with various metal vapor phase inhibitors (VCI). Using the vapor phase corrosion inhibitor soaked in the paper, the corrosive gas factors that automatically volatilize at room temperature are adsorbed to the metal surface, forming a molecular-level protective layer, achieving the purpose of rust prevention for steel. Widely used in metallurgy, military industry, machinery, auto parts, electronics, electrical engineering, hardware, and various material combinations in various industries for rust prevention and protection. This product is safe and environmentally friendly, and its performance meets the technical requirements of international advanced standards such as the relevant Japanese JIS standards and the US military standard MIL-P-3420.
Precautions for using VCI rust preventive paper
The development of industry, machinery, and products has been booming, and more and more fields and enterprises have begun to pay attention to rust prevention technology. Currently, there are many rust-free products on the market. For example, rust-free films, rust-free bags, and rust preventive paper. Today, let me introduce the working principle and characteristics of VCI rust preventive paper.
Working principle of VCI rust preventive paper: VCI material is a vapor phase corrosion inhibitor, which is a gaseous corrosion inhibitor particle that automatically volatilizes and vaporizes in the air at room temperature. It can automatically adsorb to the surface of the metal material to form protective particles, effectively destroying the environment in which corrosion is formed, blocking various corrosive factors in the environment, blocking the metal corrosion process, and achieving the purpose of protecting the metal material. The particles achieve the corrosion effect on the metal through different physical and chemical processes such as passivation, reduction, complexation of the cathode, and anode.
Precautions when using VCI rust preventive paper:
1. Electrical matters: Packaging workers must wear clean gloves. To prevent hand sweat from directly contacting the product, causing the product to rust.
2. Packaging battle: Ensure that the packaging product is dry and clean, without scale, rust, and no other corrosive chemicals attached.
3. Before packaging: The temperature of the workpiece should be consistent with the ambient temperature.
4. Working environment: The packaging work environment should avoid moisture, no acidic, alkaline, or other corrosive substances and acidic gases.
From the rust prevention indicators mentioned above, we can see that VCI rust preventive paper products each have national standards, and their respective test and inspection methods can meet national standards.
