ΜΗΧΑΝΗΜΑΤΑ ΗΛΕΚΤΡΟΧΗΜΙΚΟΥ ΚΑΘΑΡΙΣΜΟΥ ΚΟΛΛΗΣΕΩΝ ΤΗΣ NITTY GRITTY ΑΠΟ ΤΗΝ S&A FORMULA (ΣΠΑΝΟΥΔΗΣ)

PICKLING - POLISHING - PASSIVATION Nitty-Gritty’s Clinox line, born for weld cleaning on stainless steel, is the most complete, most advanced range of pickling machines available today in the world. By drawing on their inverter technology, all Clinox machines can control the flow of current. This ensures optimal working conditions, on any type of surface, and avoids irreparable damage to the stainless steel. All Clinox machines ensure the best result without wasting time because they can both pickle and passivate. Pickling means removing ferric oxide – the typical blue or bronzebrown colour – thus protecting the steel’s look and avoiding corrosion. Passivation is the restoration of the chromium oxide layer that protects the stainless steel from corrosion. The process of weld polishing needs particular care when treating steel with special finishing. There are mainly two reasons why the polishing process is so important: the need to uniform the surface of the stainless steel after pickling, and the need to favour and improve the process of steel passivation. Neutralization is the process that will stop the action of the chemical used for pickling and restores the original neutral pH, helping to start the passivation process. This process is actuated with Inox Fit, a chemical solution developed by Nitty-Gritty, which is sprayed after the pickling operation.
