Anti-rust methods other than VCI anti-rust film
In recent years, with the wide application of VCI anti-corrosion film and other VCI materials, many people have ignored other anti-rust methods. This time we will talk about 6 common anti-rust methods including VCI technology. And the difference between each other.
Common anti-rust methods include VCI technology, dry air, vacuum, inert gas, anti-rust oil, and peelable plastic. In addition to vacuum, anti-rust oil, and peelable plastic, these three methods require special methods. No other methods are needed.
The principle adopted by VCI technology is to make a sealed package or use VCIF as a sealing layer. VCI evaporates to saturate the packaging space and form a protective layer;
Dry air is generally made into a sealed package, and desiccant is used to absorb rust-causing water;
Vacuuming is to use rigid or flexible materials to make a sealed package to extract rust-causing water and oxygen;
Filling with inert gas is also first made into a sealed package, and then filled with inert gas to eliminate rust-causing water and oxygen;
The application of anti-rust oil and peelable plastic is to directly coat to form a protective layer to block the rust-causing factors water and oxygen.
The service life of VCI technology and anti-rust oil is short, medium, and long-term. Vacuum and inert gas can be sealed in a rigid container for long-term, short-term, and medium-term;
The remaining two are also available in the short and medium-term;
In terms of cost, VCI technology and anti-rust oil coating are both low. VCI technology and dry air are degradable recycling methods while vacuuming and filling with inert gas are waste or recycling.
As for coating anti-rust oil, it is right. The surrounding environment is polluted and is usually discarded. The peelable plastic coated is recyclable.
