Non-Cyanide Base Electro Chemical Polishing

Abstract

A system used in polishing the metal includes a base assembly and an electrolytic cell assembly. The base assembly has a support stand which is mounted on to a connecting element. The base assembly further includes a holding cylinder that is provided with a hook or similar kind of means that is adapted to hold an anode fixture. A process of polishing the metal using system includes providing stripping solution which is free of cyanide is taken in a glass beaker of the electrolytic cell assembly and is heated. Further, the products that are to be polished are mounted on to the anode fixture using the plurality of hooks.

1 . A system for polishing metal, said system comprising:
 an electrolytic cell assembly having:
 an anode fixture that is connected to a positive terminal and configured to receive plurality of metal to be polished; 
 a cathode that is connected to a negative terminal; and 
 a stripping solution that is configured to enable movement of ions between said anode fixture and said cathode, 
   wherein said stripping solution is free of cyanide.   
     
     
         2 . The system as claimed in  claim 1 , wherein said anode fixture is selected from titanium jig. 
     
     
         3 . The system as claimed in  claim 1 , wherein said cathode is selected from stainless steel. 
     
     
         4 . The system as claimed in  claim 1 , wherein area of said anode fixture and said cathode is maintained at 1:1 ratio. 
     
     
         5 . The system as claimed in  claim 1 , wherein said stripping solution is thiourea based solution. 
     
     
         6 . The system as claimed in  claim 1 , wherein said stripping solution is a homogenous mixture of thiourea and at least one of distilled water, reducing sugar, activating acid and wetting agent. 
     
     
         7 . The system as claimed in  claim 1 , further comprising a scrubber unit that is provided in vapor communication with said electrolytic cell assembly, wherein said scrubber unit comprises:
 a bulb that is configured to remove acidic material from fumes produced in said electrolytic assembly; and   a scrubber water that is configured to remove suspended particles from fumes produced in said electrolytic assembly.   
     
     
         8 . A method for polishing metal, said method comprising:
 preparing a stripping solution;   preheating said stripping solution;   providing an anode connected to a positive terminal and cathode connected to a negative terminal in said stripping solution; and   providing desired voltage to said anode and said cathode,   wherein said anode includes plurality of metals to be polished, and   wherein said stripping solution is free of cyanide.   
     
     
         9 . The method for polishing metal as claimed in  claim 8 , further comprising a process of cleaning fumes that are produced during said polishing metal. 
     
     
         10 . The method for polishing metal as claimed in  claim 9 , wherein said stripping solution is a homogenous mixture of thiourea and at least one of distilled water, reducing sugar, activating acid, and wetting agent.
