Natural Gas Pipeline VCI Anti-rust Powder

الوصف

VCI Powder is used for corrosion protection of metals in recessed areas, interior cavities and voids. VCI powders provide an extremely efficient dry method to protect metals within an enclosed space. The VCI vaporizes and then adsorbs on all metal surfaces, reaching every part of the metal surface, including recessed areas and interior cavities.

How VCI works:

Volatile Corrosion Inhibitors (VCI) are organic compounds that are manufactured with Low Density Polyethylene (LDPE) resin and/or Linear Low Density Polyethylene (LLDPE) resin to create Corrosion Control Packaging to stop rust.  

 VCI works by emitting VCI molecules into the surrounding area, within an enclosure space, until it is completely saturated. These VCI molecules are safe, invisible and odourless. When the VCI molecules come into contact with the air in the enclosure space, an ionic reaction takes place between the VCI molecules and the water molecules in the air.

The VCI molecules in the surrounding enclosure are hydrolyzed into VCI ions, which form a molecular corrosion protective barrier on the metal surface. This occurs through polarization, and thus passivate the substrate from atmospheric corrosion. It normally takes approximately *4 hours for the VCI ions to be absorbed on the metal surface.oximately *4 hours for the VCI ions to be absorbed on the metal surface.
