Anti-rust treatment for ball screws:
I. Surface pretreatment of the objects to be rust-proofed
1. Surface cleaning: An appropriate cleaning method must be selected based on the surface properties of the objects to be rust-proofed and the actual conditions. Commonly used methods include solvent cleaning, chemical treatment cleaning, and mechanical cleaning.
2. Surface drying: After thorough cleaning, the surface can be dried with filtered dry compressed air, or in a dryer at 120~170℃, or wiped dry with clean gauze.
II. Application of anti-rust oil
1. Immersion method: Small-sized items are immersed in anti-rust grease to allow a layer of anti-rust grease to adhere to their surfaces. The thickness of the oil film can be controlled by adjusting the temperature or viscosity of the anti-rust grease.
2. Spraying method: For large-sized rust-proof objects that cannot be treated by immersion, spraying is generally performed with filtered compressed air at a pressure of approximately 0.7MPa in a clean-air environment. This method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but complete fire prevention and labor protection measures must be implemented.
3. Brushing method: Applicable to outdoor construction equipment or products with special shapes that are not suitable for immersion or spraying. When brushing ball screws, care must be taken to avoid grease accumulation and prevent missed coating.
