Hey guys.
I am building a stripping cell. I am trying a little something different .
Rather than flat, I thought id let gravity help.
I picked up a 3ft (ballpark) 3"OD glass flange made by Buchi.
I was going to place the items to be striped at the top.
At the bottom I was going to use a PVC floor drain with glass microfiber filter at the bottom (I believe the cellouse ones would burn) with a ball valve & vaccum attachment (it needed) to drain and filter simultaniously.
Now structurally I had 2 Ideas...
I have a lead plug I made. While puring it I trimmed the ends of the corrosion resistant milspec cable. I was going to place the anode below the drain/filter. as to keep it cleaner yet still get conductivty. The basket is a bit different. I got a high grade SS mesh & Pointed stand offs. I placed it inside at the very top of a plastic/rubber cavity. It resembles one of those ball on a string toys....(does that make sense?) The pins would be enough to fill it to the end where I would use a nylon mesh just big enough for them not to fall out. The Idea is the current has to be passed through pins. the walls are inert as it the retaining mesh.
My questions are have anyone used tantalum as the Cathode or Anode. It is the best in corrosion but would it degrade from current?
Has any one tried using a small plastic pump to recirculate in a down ward motion. The filter would clean the acid prior to entering the pump.?
Any ideas as to the recommended current density and voltage. The cylinders ID is 87mm & 36in <- (dont have my tables)?
Ill try to post some imgs this morning. Please any advise would be helpful.
