Degreasing
1. Pre-Treatment Preparation
- Remove loose debris using high-pressure air/water jets.
- Mask sensitive areas (e.g., threads) to avoid over-treatment.
2. Degreasing Treatment
- Solvent Immersion: Submerge components in alkaline degreasers (pH 10-12) at 50-60°C for 15-30 minutes.
- Ultrasonic Enhancement: Optional ultrasonic cleaning for complex geometries.
3. Neutralization & Rinsing
- Wash with deionized water to remove residue.
- Acid rinse (5% HNO₃) to prevent flash rusting.
4. Drying & Inspection
- Blow-dry with filtered air to avoid contamination.
- Visual and tactile checks for uniform cleanliness.
Technical Advantages
- Eco-Friendly Formulation: Water-based solvents reduce VOC emissions.
- Precision Control: Automated temperature and pH monitoring.
- Compatibility: Validated for 304/316L and exotic alloys.
