1. Soaking method: The advantage is that it can form a uniform anti-rust film on the surface to ensure complete coverage of the product. The cost is low. The disadvantage is that it is only suitable for small products. Use low-viscosity anti-rust oil. The soaking tank must have good drainage. system.
2. Spray method: It is suitable for large-scale and complex structure products. High-efficiency sprayers must be used. It is easy that the product fails to form an anti-rust film. The working environment requires good ventilation performance during use.
3. Brush method: This method is simple to use, but it must be ensured that every position of the workpiece is brushed, and the brush must be kept clean before use.
4. Flushing method: high efficiency and recycling, which can save costs, but the products in the tank need to be drained and replaced regularly to avoid excessive moisture and other substances from affecting the anti-rust effect.
The above points are some basic knowledge about the selection and use of anti-rust oil. In the production process, it is still easy to use anti-rust oil and rust. The common reasons are: too much moisture on the surface of the workpiece and not all the workpieces The anti-rust film is formed, the anti-rust oil is used for a long time without being replaced, a large amount of water, dust, etc. remain in the oil, and the anti-rust film on the surface of the workpiece is not fully formed, and then the packaging is carried out. The moisture condensation and rust caused by the temperature difference in the package More serious, packaging materials or quality does not meet the process requirements, etc.
