The corrosion prevention and control of storage tank equipment is a vital task, and multiple corrosion prevention and control technologies need to be combined and coordinated. For the rust prevention and control of various storage tank equipment during construction, testing, work and storage, the volatile corrosion inhibitor, VCI, has been proven to have a significant effect on rust prevention and control.
VCI has advantages in comprehensive protection:
1. VCl molecules evaporate and fuse into the moisture in the air to protect the gas phase.
2. VCl molecules fall on the metal surface to form a multi-molecular film to inhibit the generation of rust.
3. VCl molecules dissolve in water, penetrate into soil or concrete, reach steel and metal surfaces, and protect them from corrosion.
4. Mixed with soil or concrete, the diffusion of gas phase makes them protect the metal surface.
