Guidelines for use of VCI paper and scope of application

Vapor Corrosion Inhibitor Paper (VCI paper for short) is a packaging material specially used to prevent corrosion of metal Products during transportation and storage. It forms a protective film by releasing gaseous rust inhibitors to prevent metal from contacting with moisture and corrosive substances in the air, thereby effectively preventing metal from rusting. VCI paper not only protects the metal surface, but also has the characteristics of environmental protection and easy use, and is widely used in many industries.

1. Guidelines for use of VCI paper
Choose the appropriate type of VCI paper

Select different types of VCI paper according to the metal materials to be protected (such as steel, aluminum alloy, copper, etc.). Different metal materials require different anti-rust papers to ensure the optimization of the anti-rust effect.
Make sure the size and thickness of the paper meet the Application requirements. For example, thinner VCI paper can be selected for small parts, while thicker paper can be selected for large equipment or products that are stored for a long time.
Packaging method

Single-piece protection: Wrap the VCI paper around the metal parts or components to ensure that the paper covers the entire surface and is well sealed. For irregularly shaped objects, the paper can be folded or cut to ensure that all surfaces are covered.
Multi-piece packaging: When multiple metal objects need to be protected, each item can be wrapped with VCI paper and placed in a carton. The amount of VCI paper can be increased inside the carton to enhance the anti-rust effect.
Stacking storage: For bulk materials such as steel, aluminum profiles, etc., VCI paper can be laid between each layer of stacked materials to form an effective protective layer.
Storage requirements

VCI paper should be stored in a dry, cool place, avoiding long-term exposure to direct sunlight or humid environments. Avoid compaction during storage to prevent the paper from losing its anti-rust effect.
During use, VCI paper should be kept away from moisture or water as much as possible to ensure that its anti-rust performance is not affected.
Precautions for use

Keep sealed: To ensure the best anti-rust effect, try to avoid contact between paper and air during packaging. When using, make sure the packaging bag or carton is tightly sealed to avoid gas leakage.
Avoid long-term contact with chemicals: The protective gas of VCI paper mainly depends on the reaction between the chemical composition of the paper itself and the metal surface, so avoid direct contact with oil, chemical solvents and other substances to avoid affecting the anti-rust effect of the paper.
Check the expiration date: The anti-rust effect of some VCI papers may gradually weaken over time. Check the expiration date of the paper before use to ensure that it can provide adequate protection during use.
2. Application scope of VCI paper
VCI paper has been widely used in many industries due to its excellent anti-corrosion performance and environmental protection characteristics. The following are the main application areas of VCI paper:

Automotive industry

Automotive parts protection: During the production, transportation and storage of automotive parts, VCI paper can be used to protect metal parts such as engine parts, chassis parts, wheels, brake discs, etc. to prevent corrosion and ensure the quality and reliability of parts.
Storage protection: Automakers can use VCI paper to protect long-term storage parts to avoid corrosion caused by moisture and air pollution during storage.
Mechanical manufacturing

Precision equipment and component protection: For precision machinery, equipment and tools, VCI paper can effectively prevent corrosion during transportation and storage, ensuring the performance and life of the equipment.
Tool packaging: VCI paper is widely used in the packaging of metal tools (such as pliers, wrenches, hammers, etc.), which can effectively prevent tools from rusting during transportation.
Electronic industry

Rust prevention of electronic components: For metal parts in electronic products (such as circuit boards, connectors, plugs, etc.), VCI paper can provide effective rust protection to prevent corrosion in a humid environment and ensure the performance of electronic products.
Protect internal components: VCI paper plays an important role in the production process of electronic products, especially in the packaging and transportation of components, ensuring that the internal parts of the equipment are free of corrosion and extending their service life.
Steel and aluminum

Long-term storage protection: Metal materials such as steel, aluminum profiles, and copper are prone to moisture and corrosion during long-term storage. Vapour-phase anti-rust paper can be used to store metal materials, protect the metal surface from oxidation, and ensure that the material is in good condition before use.
Protection during transportation: Steel and aluminum need to undergo long-term sea or land transportation during cross-border transportation. Vapour-phase anti-rust paper provides efficient protection for these materials to ensure that they are not affected by factors such as sea salt and moisture.
Ship and marine industry

Marine transportation anti-corrosion: When ships transport metal parts (such as steel, engine parts, etc.), Vapour-phase anti-rust paper can effectively resist corrosion caused by seawater. Especially during ship transportation, Vapour-phase anti-rust paper can protect the metal surface from environmental influences such as salt water and moisture.
Long-term storage protection: For equipment and components on ships or marine facilities, Vapour-phase anti-rust paper can also provide long-term anti-rust protection to ensure their normal operation.
Aerospace

Aviation component protection: Vapour-phase anti-rust paper is widely used in the aerospace industry to protect aircraft parts and tools to prevent metal parts from affecting performance due to oxidation corrosion during transportation and storage.
Long-term storage: The metal parts and components of aircraft may be affected by moisture and corroded during long-term storage. The use of VCI paper can effectively extend their service life.
Home appliance industry

Protection of metal parts of home appliances: During the production, transportation and storage of metal parts (such as compressors, metal casings, etc.) in home appliances such as refrigerators, washing machines, and microwave ovens, VCI paper can effectively prevent them from getting damp and rusting, ensuring product quality.
Summary
VCI paper is widely used in many industries such as automobiles, machinery manufacturing, electronics, steel, and aerospace due to its excellent anti-corrosion performance, environmental protection characteristics, and simple use. By using VCI paper reasonably, the loss of metal products caused by corrosion during transportation and storage can be effectively reduced, the service life of equipment can be extended, and product quality can be ensured.
