VCI rust preventive paper has excellent plasticity and can overcome the shortcomings of insufficient protection of traditional rust preventive products. They have good transparency. The effective product protection time can be one to three years.
VCI rust preventive paper is a new generation of innovative high-tech products developed based on high-polymer materials and VCI and VCI technology. After using film packaging and sealing rust preventive products, the VCI contained in the film begins to sublime, volatilizing rust preventive gas elements, penetrating the surface of the rust preventive product, adsorbing, and forming a tight monomolecular thickness protective film, isolating various factors that prevent rust from rusting, and preventing rust.
How to use VCI rust preventive paper:
1. Before packaging, the surface of the rust-proof items should be clean and dry, and they should be packaged at room temperature and room temperature, and sealed with a rust-proof film. When packaging this kind of oil, it is necessary to confirm that this kind of oil does not contain S, Cl and other chemical components. Otherwise, it will have a negative impact on the effectiveness of VCI.
2. Please wear clean gloves when packaging. Do not touch non-rusting things with your bare hands.
3. If there are protrusions or corners on the rust-proof items, please be careful not to pierce the film. If there is accidental damage, the wound should be sealed with industrial tape in time to ensure sealing.
4. During the rust-proof packaging process, the workshop should be away from "acids, alkalis and other corrosive substances and corrosive gases".
VCI rust preventive paper is suitable for ferrous metals, alloy steels, cast iron, copper, brass and bronze, electroplated metals, zinc and alloys, chromium and alloys, cadmium and alloys, nickel and alloys, tin and alloys, aluminum and alloys, stainless steel and other metal materials and products. VCI rust preventive bags have a wide range of applications and can be used as single parts or entire equipment. They have good printability and help improve the image and grade of rust preventive products.
Methods to improve the effect of VCI rust preventive paper
VCI rust preventive paper will always release a small amount of rust inhibitor (VCI definition: volatile corrosion inhibitor). After packaging with this paper, a gas protective layer is formed inside the package, which can stably control the corrosion of metal products. VCI rust preventive paper directly contacts the metal and plays a rust-proof role within a certain distance. How to improve the rust-proof effect of rust-proof paper?
Volatility can be continuously and slowly released from the rust-proof source, forming a saturated gas layer in a relatively closed space, thereby forming a rust-proof protection on the metal materials in this environment.
In summary, the anti-listening ability of VCI rust preventive paper mainly lies in VCI (weathering reliever). Therefore, the steps to improve the rust prevention effect of rust preventive paper are to select appropriate VCI (weathering reliever) according to different metal properties. By selecting good rust preventive paper according to the five standards of rust preventive paper, better protection effect can be obtained.
Before using rust-proof paper packaging, we must clean the metal products. It is necessary to prevent the appearance of water vapor and other residues on the metal surface, so as not to affect the rust-proof effect of the rust-proof paper. In addition, during the packaging process, clean rubber gloves must be worn to prevent the sweat remaining on the hands from contaminating the technical products and rust-proof paper. Compared with rust-proof oil, it is easy to operate, saves time, reduces labor intensity, makes the packaged mechanical products clean and beautiful, and avoids oil stains when using rust-proof paper to package metal materials and mechanical products in the air. Because the gas phase mitigation agent gas has no perforation, it is especially suitable for the rust-proof packaging of mechanical products with complex shapes. When using gas phase rust-proof paper packaging, it is not necessary to apply oil to the metal surface in advance. Compared with other rust-proof packaging materials, the rust-proof effect is good and the rust-proof period is long when using meteorological rust-proof paper packaging. Generally, the rust-proof machine of commercially sold meteorological rust-proof paper is around 2~3 years.
