Purifying additive TsK-1 for cleaning alkaline (zincate) electrolyte from hexavalent chromium ions

Products: Cleansing additive TsK - 1 buy wholesale price manufacturer Russia, Republic of Bashkortostan

Additive TsK - 1 Purifying additive TsK - 1 for cleaning alkaline (zincate) electrolyte from hexavalent chromium ions, when electrolyte is contaminated by transfer of chromium from a passivation or etching bath.

Additive TsK - 1 is an aqueous solution of reagents, which is introduced directly into the working electrolyte like brightening additives. After the introduction of CK - 1, the electrolyte is stirred and then filtered or decanted.

The presence of chromium contamination is determined by analytical methods, or by the characteristic signs of coating defects: significant darkening at low and medium current densities (0.2 - 4) A / dm2, which is not removed by current processing and a decrease in zinc current efficiency.

Dosage:

The dosage of the CK - 1 additive depends on the concentration of the pollutant and usually does not exceed 3 ml / l. The exact amount of cleaner can be determined by testing the electrolyte in a Hull cell.

Additive TsK - 1 can be used with brighteners TsM, TsPB, TsB, TsVB or their analogues.
