The vapor phase anti-corrosion bag is customized with high-quality anti-corrosion plastic film, and after encapsulating the protected items, The VCI contained in the bag begins to sublime and volatilize the anti-rust gas factor, and the sublimation diffuses to the surface of the anti-rust item and adsorbs on it.
Forms a dense protective film with a single molecule thickness, which not only isolates the direct contact between atmospheric corrosion factors and the metal surface, It also blocks the displacement of electrons in different energy regions, thereby effectively avoiding the generation of rust.
Advantages of VCI bag:
1. It has excellent gas phase and contact anti-rust performance, good anti-rust effect, and high-cost performance;
2. Clean, harmless, non-toxic, environmentally safe, and safe. Pass the SGS certification and comply with the RoHS directive requirements;
3. The anti-rust items can be used immediately without degreasing and cleaning. Save labor and time, improve work efficiency and save costs;
4. Transparent and beautiful, the anti-rust items are dynamically visible and easy to identify;
5. Wide applicability. It can be used as small as a single part or as large as the entire equipment.
6. Good printability, which helps to improve the image and grade of anti-rust articles.
Precautions for the use of VCI bags:
1. Preliminary matters—Packaging workers must wear clean gloves to work to avoid direct contact with the product by hand sweat and make the product rust.
1. Preliminary matters—Packaging workers must wear clean gloves to work to avoid direct contact with the product by hand sweat and make the product rust.
2. Early stage of packaging — Confirm that the packaged product is dry and clean, free of water stains, rust, and no other corrosive chemicals attached.
3. Early stage of packaging — The temperature of the workpiece should be kept consistent with the temperature of the space.
4. Operating environment — The packaging operating environment should avoid excessive moisture and no acid, alkali, and other highly corrosive substances and corrosive gases.
5. Packaging process — When using anti-rust materials, the side with corrosion inhibitor should face the metal product.
6. Packaging process — VCI product and workpiece must be as close as possible, the distance should not exceed 30cm, and no other barriers should be placed between the two. The closer the distance, the better the effect.
7. Packaging process—If there are barrier materials such as paper backing boards, wood, plastic partitions, etc. between the metal to be packaged and the anti-rust film, pay special attention to the barrier materials not directly contacting the metal products. In order to avoid the barrier material containing S, CL chemical composition, affect the anti-rust effect.
8. Packing space—When lining packaging for large equipment and packing densely arranged products, it is recommended to use it with other VCI materials, such as anti-rust paper, anti-rust powder, etc.
