Today I will bring you a relatively advanced paper introduction-VCI paper.
VCI paper belongs to industrial paper, which is generally used in the outer packaging of various metals and plays an extremely important role in preventing metal rust.
Among the many materials in the packaging industry, VCI paper is a high-tech product, and its core technology is embodied in VCI (Vapour Inhibitor).
VCI technology is a comprehensive technology that integrates organic synthesis, physical chemistry, corrosion and protection, metal materials, paper processing, and polymer technologies. Because of the existence of this VCI, VCI paper has achieved a good rust prevention function.
Different VCI systems have big differences in safety, high efficiency, environmental protection, and applicability, so they are embodied in products of various forms and functions.
What is VCI
As the name implies, VCI is a kind of rust inhibitor with volatile energy. It is a high-tech anti-rust product made up of dozens of chemical raw materials through chemical processes.
Principle of VCI
VCI products have corresponding volatilization functions.
When metal products are covered in a relatively confined space or are in close contact with metal products, it will automatically volatilize anti-rust ions according to the temperature and humidity of the environment.
These anti-rust ions will fill the entire closed packaging space and is in a dynamic saturation state.
At the same time, these chemical ions will also have a microchemical reaction with the environmental media (water vapor, oxygen, or other chemical media) in the packaging space, effectively reducing the environmental media’s effects on metals.
Corrosion, so as to achieve the purpose of protecting the metal from corrosion.
The advantages of weather rust-proof paper:
1. Realize oil-free packaging, no smearing, degreasing, and cleaning procedures, saving labor, time, and cost.
2. Effective rust prevention can be achieved even if it is not in direct contact with metal, especially suitable for metal parts with complex appearance.
3. It has dual functions of anti-rust and packaging.
4. Compared with vacuum packaging, the cost is low and the use is simple.
5. Clean, harmless, non-toxic, environmentally safe and safe. Pass SGS certification and comply with RoHS directive requirements.
