1. Manual rust removal method
Use scrapers, hand hammers, steel brushes, grinding wheels and other tools to knock, shovel, grind, scrape, etc. to remove rust.
2. Mechanical descaling method
Use portable electric grinding wheels, electric brushes, pneumatic brushes, rust removal guns, etc. to effectively remove rust and its dirt by impact and friction. The most widely used methods are jetting and shot blasting.
3. Chemical treatment
The acid solution is used to chemically react with the rust (oxide) on the metal surface to be cleaned, so that it is dissolved in the acid solution. In addition, the hydrogen generated by the action of the acid and the metal causes the oxide skin to fall off mechanically.
4. Ultrasonic treatment
Use high-frequency vibration to shake off the crisp rust.
Emerging #Laser rust cleaning super simple
Using laser irradiation, the oxide, coating, dirt and other structures on the metal surface are relatively loose to be removed, and after absorbing short pulses of high-energy laser light, they are ionized and leave the metal surface to achieve a cleaning effect.
No chemical lotion, dry ice, cleaning jet and other consumables are required, and the cleaning effect is uniform and fast, easy to operate, light and convenient
