1. organic solvent degreasing
Features: Saponified oil and non-oil can be dissolved, and generally do not corrode parts. Degreasing speed is fast, but it is not complete, and chemical or electrochemical methods are needed to supplement degreasing. Organic solvents are flammable; Toxic and expensive.
Scope of application: It can degrease small parts with complex shapes (seams and blind holes), non-ferrous metal parts, parts with serious oil pollution and parts easily corroded by alkaline solution.
2. Chemical degreasing
Features: simple method, simple equipment, low cost, but long degreasing time.
Scope of application: degreasing of general parts.
3. Electrochemical degreasing
Features: high degreasing efficiency, which can remove mechanical impurities such as floating ash and wet slag on the surface of parts. However, cathodic electrolytic degreasing parts are prone to hydrogen permeation, and deep-hole oil pollution removal is slow, which requires DC power supply.
Scope of application: degreasing of general parts or anode dehumidification slag.
Wipe and degrease
Features: flexible and convenient operation, not limited by parts, but high labor intensity and low efficiency.
Scope of application: large and medium-sized parts or parts that are not suitable for degreasing by other methods.
5. Drum degreasing
Features: high efficiency and good quality, but not suitable for large parts and deformable parts.
Scope of application: small parts with low precision.
6. Ultrasonic degreasing
Features: low corrosiveness to matrix, high degreasing efficiency and good purification effect. The corners, fine holes, blind holes and inner walls of cavities of complex parts can be completely degreased.
