I. Common Rust Problems in Steel Plate Storage:

Steel plate, a key product of metallurgical enterprises, is widely used in industries such as construction, machinery, automobiles, and shipbuilding. However, during transit and storage, the surface of steel plates is extremely susceptible to environmental factors, leading to rust. Especially in the high humidity of southern China, at coastal ports, and during international transportation, corrosive media such as moisture, salt spray, and sulfur dioxide in the air accelerate oxidation reactions, causing rust spots on the steel plate surface.

Variations in storage conditions are also a major cause of rust. For example, after cooling from high temperatures, condensation easily forms on the surface of steel plates. In open-air or semi-open warehouses, rainwater infiltration and fluctuating humidity levels create a rust-prone environment for steel plates. Once rust occurs, it not only deteriorates the appearance of the steel plate but can also affect other properties.

II. How VCI Anti Static Film Works:

VCI Anti Static Film is a new type of vapor-phase rust-inhibiting packaging material that releases vapor-phase corrosion inhibitors within the packaging environment. These molecules diffuse evenly and adsorb onto the steel plate surface, forming a dense, transparent molecular protective film that blocks moisture and oxygen from the air from coming into direct contact with the metal, preventing rust.

Compared to traditional oil or wax coatings, VCI Anti Static Film offers significant advantages. First, it doesn't leave a heavy greasy stain like oil-based rust inhibitors. Subsequent processing steps like cutting, welding, and painting can be directly applied without degreasing or cleaning, significantly reducing both process steps and labor costs. Second, VCI Anti Static Film is an environmentally friendly material. CVCI's VCI Anti Static Film complies with international standards such as RoHS and REACH, eliminating the environmental risks associated with the use of chemical oils. Furthermore, VCI Anti Static Film's high transparency allows warehouse staff to easily inspect the steel plate surface without unpacking, facilitating management and inventory.

III. Advantages of VCI Anti Static Film in Steel Plate Transit Storage

VCI Anti Static Film enables complete packaging, creating a sealed "protective cabin" that effectively isolates external moisture, dust, and corrosive media. Furthermore, VCI Anti Static Film is highly adaptable and can be flexibly applied to steel coils, steel plates, and cut and formed components, meeting varying sizes and stacking requirements. CVCI's VCI Anti Static Film, rigorously laboratory-tested, provides a protection period of six months to two years, making it ideal for long-distance shipping and long-term storage. Anti Static VCI Film eliminates the need for post-cleaning, reducing the use of cleaning agents and wastewater discharge, aligning with current trends in green production and environmental conservation. VCI Anti Static Film is the most cost-effective rust prevention solution for steel plate transit storage.

IV. Application Scenarios:

China Composite VCI Film has a wide range of applications in steel plate transit storage. For steel mills, finished steel plates often require a period of storage after production before shipment to customers. Using China Composite VCI Film packaging during storage in warehouses can prevent rust during inventory. For logistics companies, using China Composite VCI Film during transit storage and transportation can reduce cargo loss and improve overall transportation quality. A steel exporter had long been plagued by rust during ocean shipments, leading to frequent customer returns and negatively impacting its brand reputation. By using CVCI's China Composite VCI Film metal packaging, the company's products were reliably protected during ocean shipments, significantly improving customer satisfaction. This improvement not only reduced direct losses but also enhanced its competitiveness in the international market.
