Equal processing procedures collaboration solves, and be easy to cause and mutually shifts responsibility onto others, delays the situation of project process.When aluminum component and plastics have 0.03mm~
When the gap of 0.05mm sizes, acid solution can be kept in anode oxidation process, acid solution can not be washed out by common table tune,
In dyeing course, acid solution is precipitated, and changes local pH, leads to not the bad referred to as acid regurgitation for normally catching color.Existing table
It is that an Optimization for Ultrasonic Wave and table are adjusted to adjust tank liquor, and acid regurgitation cannot be prevented completely by no matter how optimizing, to more difficult product without bright
Effective fruit.
