VCI vapor phase anti-corrosion paper is made of high-quality anti-corrosion base paper and high-efficiency compounded special vapor phase corrosion inhibitor (VCI LIQUID), processed and refined through a special process.
In the sealed packaging space, the VCI contained in the paper begins to sublime and volatilize the anti-rust gas factor under normal temperature and pressure, diffuse and penetrate to the surface of the anti-rust item and adsorb on it, forming a dense protective film layer with a single molecule thickness, thereby achieving The purpose of rust prevention.
The anti-rust principle of VCI VCI paper is to effectively combine VCI with neutral desulfurized kraft paper.
The paper can be directly vaporized at room temperature, and in a sealed environment through continuous volatilization, it will make any space gap in the packaging unit Will be filled with mixed gas containing VCI corrosion inhibitor components.
When this gas contacts the metal surface, the VCI molecules are concentrated and decomposed by the existing moisture to form free protective ions to dissolve into the electrolyte.
The ions in the electrolyte react with VCI ions, replacing metal molecules attached to the metal surface, and inhibiting the electrochemical reaction of metal corrosion.
The VCI molecules will slowly volatilize, so that the packaging space is always in a “saturated” state, achieving a long-term stable anti-rust effect.
The carrier of VCI vapor phase anti-corrosion paper is anti-corrosion base paper. After VCI liquid coating, VCI will be slowly released from kraft paper in a suitable space, forming a saturated gas layer in a relatively closed space.
The metal material forms anti-rust protection. At present, the types of VCI VCI paper are divided into VCI paper for multi-metals, VCI paper for ferrous metals, and VCI paper for copper and aluminum according to the different materials of the packaging materials.
According to different specifications, VCI VCI paper Varieties are: bleached type, unbleached type; coated type, wrinkle type, coated wrinkle type, and use different VCI grades for different metals.
Performance characteristics of VCI VCI paper:
1. The operation is simple, no pretreatment of the metal surface to be protected is required, no oiling, oiling, and cleaning processes are needed, labor and time are saved, work efficiency is improved, and costs are saved.
2. Wide range of applications. It can be packaged as small as a single part or as large as the entire equipment.
3. High transparency, without opening the package, you can clearly distinguish the items in the film.
4. It has the characteristics of polyethylene and is free from salt damage. Corrosive gas, high temperature, and high humidity. As long as the product is packed with a layer of anti-rust film, it can play a super anti-rust function.Even in the humid environment of marine transportation and the polluted atmosphere, a better anti-rust effect can be obtained.
- 5. Comprehensive anti-rust performance, for any irregular surface items, it can prevent rust in all directions without leaving any dead ends.
- 6. Long anti-rust period, generally 2 to 5 years.
7. Use clean, safe, non-toxic, harmless, and fully recyclable.
8. The unique monomolecular protective layer has no adverse effect on the metal in the package.
