VCI paper is a special anti-rust packaging material made of special neutral paper as the base material, coated with different combinations of special substances-VCI, and processed through a series of post-processing.
Among the many materials in the packaging industry, VCI paper is a high-tech product, and its core technology is embodied in VCI.
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 great differences in environmental protection and applicability, which are reflected in products of various forms and functions.
VCI anti-corrosion paper in a sealed environment through its own adjustable continuous volatilization, so that any space gap in the operating unit will be filled with mixed gas containing VCI anti-corrosion factor, this gas will be adsorbed on the metal surface, forming Only one or a few molecules thick dense protective film layer.
VCI paper is a proprietary formula containing VCI, which can place polyethylene film that rusts on iron and non-ferrous metals and VCI.
It is mixed in the film, rather than the shallow surface of the surface, and volatilizes in a closed environment through an invisible, highly effective vapor phase anti-rust molecule.
Prevent metal from adhering to the surface and corners of metal objects, causing moisture, salt, oxygen, dirt, and other substances that cause the material to be retested.
It is impossible to directly accumulate on the metal surface to prevent the metal from rusting. The anti-rust film has a transparent appearance and is easy to identify parts visually and visually.
Simple, safe and efficient packaging is very useful for long-term inventory, export goods, assembly processes, etc.
How to use VCI paper:
1. Manual or machine winding, so that the protected metal products are wrapped and invaded by waterproof gas;
2. Use vapor phase anti-corrosion packaging materials correctly in accordance with the provisions of GB/T14188;
3. Ensure that the packaging metal materials are clean and dry;
4. The surface containing the corrosion inhibitor faces the metal package;
5. Ensure relative sealing after packaging.
