Electrolytic copper foil processing

The treatment of electrolytic copper foil in general there are many surface defects in the scene can be handled in a timely manner, and some can be timely prevention, the following look at it may be a problem:


Galvanized surface color uneven

1.1# copper plating bath has poor plating ability, and the dosage is not enough.

2.4# zinc bath pH value is acidic, zinc is dissolved.

3.4# zinc plating anode plate DSA coating off, replace the anode plate.

4.after washing water pressure is too large, rinse off the zinc coating:

 

Corrosion point in production process

1. red dot for electrolytic copper foil surface treatment before the acid etching point.

2.-新葡京高尔夫赌场black spots are produced after surface treatment of electrolytic copper foil. Need to be stored for a period of time before being exposed.

3. white (bright spots) due to the production of space humidity, fog point caused by falls on the copper foil surface after a period of time.

More than 4 points to deal with measures: to control the production of space humidity, strengthen air convection.
