How to choose anti-rust oil and how to use it?
Of course, first choose a reliable anti-rust oil. Since the amount of anti-rust oil is not large in our country, many anti-rust oils are produced by small local factories or even made by users. At present, the quality of some major domestic anti-rust additives is not stable enough or the oil solubility is not good. Therefore, first visual inspection before use, from the appearance Compared with the previous batches in terms of color, layering or unevenness, etc. If the appearance of several batches is quite different, the quality should be doubted. For users who consume a large amount of anti-rust oil, a humid box test equipment should be provided to verify the anti-rust effect of the anti-rust oil. Heavy oil cleaning agent
Selection principle
1. According to the type of metal, different anti-rust oils have different anti-rust effects on different metal materials. Some have good anti-rust effects on ferrous metals, but have general effects on copper. These are often included in the product description materials of anti-rust oil. Will explain, should pay attention to selection.
2. According to the structure and size of the metal product, the solvent-diluted type or the grease type can be selected for the simple structure and large surface area, while the oil type is better for the complex structure with holes or cavities, because the anti-rust film should also be considered when unsealing. Divisibility.
3. According to the environment and use of the metal product, distinguish whether it is a short-term process anti-rust, or a long-term anti-rust with short-term lubrication, a long-term seal anti-rust for a humid environment, or it may be stored in a coastal warehouse or even Sea transportation for a certain period of time requires good salt spray resistance. The selection must be targeted in this regard.How to choose anti-rust oil and how to use it?

Precautions
Generally short-term or process rust prevention, the rust prevention work is completed after applying the above-mentioned rust prevention oil, but for long-term sealing and rust prevention, packaging must be carried out to protect the rust prevention film from damage in the transportation inventory and reduce the invasion of corrosive media. Generally, oily, well-sealed, and soft-film materials such as plastic film, aluminum-plastic film, wax paper, etc. are commonly used.
Regarding the selection of anti-rust oil, it also has a very large relationship with the environment. In addition to the length of the anti-rust time, we should choose different types of anti-rust oil with some special functional requirements.
