Back to the heaters plating up....... here is what we do in our tanks.

We actually use a separate axillary rectifier such as a laboratory or hull cell rectifier. You would not want to use a large capacity rectifier because all you need to impose is a very small "trickle" of direct current.

An anodic charge should be imposed on the outside shell of the titanium (or stainless) heater above the solution level. We run a small wire from the cathodic side of the axillary rectifier to a small piece of carbon and place this carbon cathode within about 6" of the heater. Then we adjust the output of the axillary rectifier to about 1/2 volt dc. This small secondary electrical input should have no side effects. It is important that the wire connections to the heater and carbon cathode be above the solution level. At the voltage I recommend, you will see only see about 1 ampere. The amperage is limited by the size of the cathode.

The shell of the heater is connected to the factory gro …

Hello Subrata,

Welcome to the Finishing Talk Forum! We are pleased to have you as a fellow member. What is metal finishing like in Kolkata? Are there many other metal finishing - powder coating and plating shops in your town? Do you have a metal finishing organization (club or association) that meets in your city? Does it have environmental laws and concerns as we do in the US?

As to your question..... I would look into White Bronze as a non-nickel replacement. This is an old automotive plating process that is being resurrected to be used now because of the new European laws pertaining to Ni that touches the skin. Carolina Process Control (CPC) is a member here and I know they have experience with that process. You should message them. Good luck and welcome.

I for one would be interested in this type of education. And I wonder what is already out there??? Do any courses like this exist - anywhere in the world?? Feedback from the Finishing Talk Community would be interesting.......

Now I've seen it all......kudo's to the Pauls. This industry can use more fresh ideas like this. Can't wait for the next show, and you can consider me a fan. Keep up the good work!

Do you think that this equipment could be bought for 50 to 60k? Thanks.

Thanks for sharing that information - I've often thought about these very same issues. We have small tanks and use constant filtration with flo-king filters. When I need to carbon treat I add a carbon filter to the flo-king.

Being a Civil War buff I do like your analogy. But I think Fort Sumter was when our (out of control BOD) voted to accept the merger..... that is where the real first shot was fired from the traitors. Sur-Fin 07 will be more like Gettysburg!

Since when did the AESF BOD start working for the other associations? Aren't they supposed to look out for the AESF membership first? Thank God we have a Council of Delegates left to protect the members.

We currently have two Nordson Sure Coat Powder Application systems and would like another as a back up. Please let me know if anyone out there has one for sale.
