Factors affecting alkaline oil removal before etching the label with an etching machine

發布時間:2020-10-30

Metal sheet metal Etching machine There are many complex factors that affect the degreasing effect of alkaline solution before etching, but the main influencing factors include whether the ratio of various components in the alkaline degreasing solution is reasonable, the temperature of the degreasing solution, the material and oil content of the degreased workpiece itself. Have reinforcement measures been taken during the oil removal process and is the designated oil removal time sufficient.
1. Types and surface states of metallic materials
Workpieces made of different metal materials in alkaline oil removal should have different oil removal formula machine process parameters.

2. The influence of various components and contents of oil removal fluid.

3. Operating temperature of degreasing fluid
Generally, the operating temperature should not be too high. On the premise of ensuring the oil removal effect and quality, the higher the operating temperature, the better. Adding a small amount of efficient surfactant can enhance the wetting, permeation, and emulsification processes, reduce the temperature, and ensure the effectiveness and quality of oil removal.

4. Strengthening measures for oil removal

5. Oil removal time
The oil removal time depends on various operating conditions. Firstly, the straight alkali solution is better, especially when the alkali solution is used at the beginning and has a good effect, the required time is shorter.

6. Cleaning with thick oil removal
