Product Description

Key Component

1. Stainless steel plate made up of S/S Type 316L
Standard: ASTM A240/A240M
Dimension: 1115*991*3.25mm
Tolerance of length and width: ±1mm
Tolerance of nonflatness: ±2mm
Tolerance of diagonal: ±1.5mm
 

Stainless steel should be resistant to general pitting and corrosion, there should be no defects on the surface of the sheet, and burrs are not allowed on the edges of the sheet.

The lower edge of the cathode sheet has a v-groove (90°) for peeling off the copper cathode easier.

 

2. Headbar made up of Type Copper T2
Standard: GB/T 5231
Dimension: 1270*25*50mm
Maximum Tolerance of length: ±1.0mm
Tolerance of horizontal and vertical: ±1.0mm
Tolerance of width and height: ±0.25mm 
 

The ends of the conductive rod (connect and support portions) shall be rounded to ensure that the cathode is positioned vertically above the electrolyser cell. The exposed copper surface should be smooth and free of impurities.


3. Edge strip made up of PPO or ABS
Dimension: 1090*φ9mm

 

The edge strips should be secured installed along the edges of the sheet to prevent overgrowth of the cathode copper.
