Controllo delle soluzioni
The control is carried out by determining the total acidity of the bath in the following way:
10cc of bath is taken
A few drops of methyl orange indicator are added
It is titrated with NaOH N / 10 solution until it turns from red to yellow
From the number of cc used in the titration it is possible to trace the concentration of the following bath:
CONCENTRATION gr / lt SCORE
20 11.0
40 22.0
50 27.5
70 38.5
Alimentation
Removal of thermal oxides (calamines) from raw materials or semi-finished products
Removal of processing oxides and oily residues or emulsions
Etching, pre-painting, pre-conversion treatments
Burnishing and satin finishing
Final cleaning of the finished product, with preservation of tolerances
Precautions
Everything that comes into contact with the solution must be made of 316 / L stainless steel or antacid material.
