Features
Using timing control function, the setting is simple and convenient, and the working time of positive and negative current polarity can be arbitrarily set according to the plating process requirements.
It has three working states of automatic cycle commutation, positive and negative, and reverse, and can automatically change the polarity of the output current.
How to install rectifier
This is installation way for remote control rectifier. Not only this way.
1. To connect copper bar with bath/tank
2. To ensure power supply/rectifier is grounded
3. To ensure there is enough water for water cooling type power supply/rectifier
4. We advice that all rectifiers should be isolated to increase of its life.
How does electropolishing work?
In electropolishing, the metal part or work-piece serves as the positively-charged anode. The work-piece is connected to the positive terminal of a DC power rectifier. The negatively-charged cathode, generally made of stainless steel or zirconium, is connected to the negative terminal of the DC power rectifier.
Both anode and cathode are immersed in a temperature-controlled bath of electrolyte solution, typically consisting of a high-viscosity mixture of sulfuric acid and phosphoric acid.
Electrical current from the rectifier is conducted from the anode to the cathode through the electrolyte. The electrical current causes metal ions on the surface of the part to oxidize and dissolve into the electrolyte. This process can dissolve extremely small, tightly controlled amounts of metal, resulting in micron-level thickness of surface removal.
The amount of metal surface removal is controlled by the following factors:
- Electrolyte chemical composition
- Temperature of electrolyte (typically 170 °F – 180 °F)
- Length of time of exposure to electrical current
- Density of electrical current (varies by electrolyte; typical range is 140 – 250 amps per square foot)
- Composition of metal alloy undergoing electropolishing
