METALFIP 312 is an acid deoxidizer designed for the removal of surface oxides and for the conversion of aluminum and its alloys in the pre-chromating and pre-phosphochromatizing phase.
Usage and Applications
To obtain an excellent deoxidation result, it is advisable to operate in multi-stage treatment plants to ensure excellent cleaning of the artifacts.
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
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
Everything that comes into contact with the solution must be made of 316 / L stainless steel or antacid material.
Hydrofluoric and nitric free
Excellent longevity of the baths
Pickling and phosphating action
Degreasing of oils and protective agents
Cleaning and degreasing of aluminum and alloys
Pre-conversion treatments (e.g. pre-chromatization)
