ANTI-RUST OIL
time:2018-05-04
1、Anti-rust oil function

Anti-rust oil is a kind of industrial liquid designed to prevent corrosion of metal corrosion, mainly based on basic oil (or water), combined with high efficiency corrosion inhibitor, auxiliary additive and so on.

The principle of anti-rust: a dense layer of membrane is formed by physical or chemical adsorption on the metal surface, it can cover on the surface of the metal completely, isolate the contact and entry of some rusting factors such as oxygen, water and so on; and at the same time, the electrode is quickly covered, the electric field is stopped and the electric charge is removed from the metal surface when the electric field is produced. To avoid electrochemical corrosion and to prevent rust.

2、Performance requirements for anti-rust oil

In addition to having good rust prevention function, it also has other functions and functions, such as lubrication, cleaning, vibration reduction and so on.

Low viscosity

The viscosity of anti-rust oil should be reduced as far as possible when meeting the requirements of use. Low viscosity and easy coating, and can effectively reduce the thickness of rust proof oil, and achieve the purpose of saving and reducing losses. 

Higher environmental requirements

With the increasingly stringent requirements of environmental regulations, it is necessary to try to adopt environmentally friendly rust preventive products.

3.   Selection criteria for anti-rust oil

⑴ According to the metal varieties, different anti-rust oils have different anti-rust effects on different metal materials, and some have good anti-rust effect on black metal, but the effect of copper is general, and should be chosen.

⑵ According to the structure and size of the metal products, the structure is simple and the surface area is large, and the solvent diluent type is good, but the structure with the hole or the inner cavity is better, because the anti-rust membrane is also considered to be removed when the seal is unsealed.

⑶ According to the environment and use of metal products, it is needed to make clear whether it is a short-term process of rust prevention, or a long term corrosion protection with short term lubrication.

⑷ According to the influence on the appearance of metal products, for example, when the metal products are anti-rust in the short term, when they are packed without cleaning, it is necessary to consider whether the anti-rust oil will affect the appearance and appearance of the product, and can choose the varieties of anti-rust oil that volatilized quickly and with light color.
