1. The first process: surface cleaning
The mechanical scrubbing cleaning method is adopted, and the surface of the equipment is wiped and cleaned with a cleaning cloth dipped in a mixture of disinfectant alcohol and water with a concentration of more than 90%.2. The second process: surface drying
After cleaning, use filtered dry compressed air to dry, or use a dryer at 120~170 degrees Celsius, or directly dry with a clean rag.3. The third process: coating of anti-rust oi

is generally coated with anti-rust oil by common brushing and spraying methods.
①Brush coating method:
After dipping anti-rust oil with a brush, apply it to the surface of clean metal parts. During the brushing process, make sure to brush evenly horizontally and vertically, to prevent uneven thickness from generating oxygen concentration cells on the metal surface and causing corrosion in the thick layer of the coating.②Spraying method:
Use a high-pressure jet to coat the surface of clean metal parts with anti-rust oil. During the spraying process, the spray gun is selected according to the viscosity of the oil, and the appropriate pressure is controlled to ensure that the oil mist is sprayed evenly without filamentous oil or discontinuity. At the same time, during the spraying process, control a certain oil temperature and spraying distance, and extend the coating on the production surface in a certain direction.
