Rust causes loss of property and causes various accidents. Measures can be taken to reduce the loss of corrosion and save resources, energy and funds. At present, the most commonly used method of rust prevention in industry is coating antirust oil on the metal surface (commonly known as butter), but this method is invalid due to the oxidation of antirust oil itself. It is time consuming and labor consuming to remove the protective layer, which is neither sanitary nor safe. The use of desiccant to prevent rust is low cost, simple operation, but the effective time is short, and it is greatly influenced by the environmental temperature. As for the use of special dehumidification equipment to package metal materials, although the antirust effect is good, the cost is high and time consuming and labor consuming, the operation is also complex. It is more and more convenient and practical, both safe and effective gas phase antirust packaging (VCI) has attracted more and more people's attention.
Characteristics：lasting effect, easy operation, nondestructive to products
Principle：VCI is a volatile corrosion inhibitor, referred to as a gasifying antirust product. The technology of gaseous phase antirust packaging is to use the gaseous phase inhibitor (volatile corrosion inhibitor) to rust the metal products in the sealed packaging container. When the antirust product is packaged, the antirust particles of rust proof products are gasified into gas, forming protective films on the metal surface, cutting off the possibility of metal ions contacting with water and oxygen, so as to achieve the antirust effect. At the same time, for other rust proof products, The most difference of our company's antirust products is The gas diffusion of the anticorrosive particles inside the package is automatically adjusted. When the temperature increases, diffusion amount of antirust particles will increase. On the other hand, the diffusion amount of antirust particles will decrease. But when the outside temperature is stable, antirust particles will temporarily stop volatile, maintain an optimal antirust state, until the outside temperature changes again, antirust particles will again volatile, so as to automatically adjust the concentration of the gas inside the packaging, packaging has always been in a stable state of the antirust state.
Product types：gaseous phase antirust paper, gaseous phase antirust film, gaseous phase antirust agent, gaseous phase antirust buffer material, gas phase antirust oil, etc.
Applicable object: military industry, machinery and equipment manufacturing, electronic instrument and instrument industry, automobile industry, metallurgical industry, etc. which parts that need to be protected against rust.
