In spring, spring rain and humidity are accompanied by it. At this time, rust prevention of workpieces is very important. There are anti-rust paper and anti-rust bag film on the market, both of which can be used for packaging anti-rust. What is the difference between the two? How to use it better?
Today, I will give you the advantages and disadvantages of anti-rust paper and anti-rust film for popular science, so that you can choose.
About anti-rust paper: the price is relatively low, the air permeability is slightly better, and the action speed is fast. The vapor phase rust preventive effect is better than the vapor phase rust preventive film, and the effective time is shorter.
But compared with the anti-rust film: it is opaque, the strength and toughness are not enough, and the paper may fall off.
Regarding the anti-rust film: transparent, strong maneuverability, relatively sealed packaging, better barrier properties. Disadvantages: It is easy to restrain the water vapor in the internal environment and make the humidity stable for a long time.
Of course, it is necessary to distinguish the functions of anti-rust paper and anti-rust film. Jiapu Antirust recommends that you look at the specific application field, and you can’t say which one is better.
For example, packaging more precise parts, meters, and anti-rust paper may not be suitable. The falling paper fibers will give you a headache. However, in places with high humidity on site, it is not suitable to directly use anti-corrosion film for bagging, because it is easy to restrain water vapor, and it is best to use it with a desiccant.
1. There is oil or impurities on the workpiece.
2. In the cleaning equipment, spray water-based cleaning agent on the workpiece.
3. High-temperature drying of the workpiece in the cleaning equipment.
4. After the workpiece is cooled, it is packaged in VCI and covered with anti-rust paper.
5. Finally, install the anti-rust film.
