VCI rust preventive paper is a new type of rust preventive packaging material. It is made by coating vapor phase corrosion inhibitor on rust preventive base paper. Vapor phase corrosion inhibitor is a corrosion inhibitor prepared by special synthesis technology and compounds.
VCI rust preventive paper can be directly vaporized or attached to a suitable carrier at normal temperature and pressure. In a sealed environment, any space gap in the operating unit will be filled with a mixed gas containing VCI rust preventive factors through self-regulating continuous volatilization. When this gas encounters a metal surface, it will be adsorbed on it, forming a dense protective film only one or several molecules thick. The protective film can effectively isolate the metal surface from contact with moisture, oxygen and other harmful atmospheric corrosion factors, control the occurrence of electrochemical reactions that promote metal corrosion, and thus achieve the effect of corrosion prevention.
VCI rust preventive paper is another name for vapor phase rust preventive film. VCI rust preventive paper products combine modern film technology with vapor phase corrosion inhibition (VCI) technology. Through a special process, PE resin and VCI are blended and co-extruded and blown to form the product. VCI rust preventive paper is characterized by transparency, good barrier properties, long rust prevention period, and ease of use. It is a new generation of economical and environmentally friendly rust preventive packaging material.

What are the applications of VCI rust preventive paper? Let's take a brief look together.
1. Automotive and motorcycle fields: bearings, clutches, motors, valves, and various metal parts. 2. Machinery field: machinery parts, medical machinery, instruments. 3. Steel mills: carbon steel, alloy steel, cast iron, steel phosphating, steel nitriding, steel bluing, powder metallurgy, grain-oriented silicon steel, non-grain-oriented silicon steel, etc. 4. Various cast iron parts, power tools, hardware, powder metallurgy, measuring tools, cutting tools, and aviation parts. 5. Various copper, aluminum, tin, cadmium, silver, and zinc parts.
How should VCI rust preventive paper be packaged and stored? Let's take a brief look together.
1. The product should be stored in a dry and cool place, sealed to prevent damage to the original packaging. 2. Shelf life is two years from the date of production.
How is VCI rust preventive paper used? Let's take a brief look together.
1. Use vapor phase rust preventive packaging materials correctly according to GB/T 14188. 2. Use as single-piece rust preventive packaging material for metal parts, or as a layer pad or inner patch for packaging units. 3. Products with polyethylene coating have a certain waterproof function and can be directly used as outer packaging materials. 4. Ensure that the packaged metal materials are clean and dry. 5. Wrap the surface containing the corrosion inhibitor with metal. 7. Ensure the relative airtightness of the packaging.
