Cleaning of Metallic Surfaces

Apart from the use of salt baths for the heat treatment of metals, the cleaning of metallic surfaces with oxidant salt baths is a process commonly used in modern manufacturing plants.

Cleaning salts can be used to remove several kinds of residues, such as: porcelain and vitreous enamels, residues of casting sand based on zirconite and alumina, residues of scale in stainless steels, heat resistant steels, titanium and its alloys, metallic oxides and residues of molding sand based on silica, paint of production parts and devices, polymers in extruding dies with multifilament, oil and paint of engines for reconditioning, paint, resins and shellac residues at aluminum, zinc and other materials not resistant to chemical reactions and high temperatures, residues of synthetic fibers, rubber and other organic substances, such as polyamide, polypropylene, polystyrene, PVC, acrylic esters and polyester, residues of sand in cast parts made from aluminum and its alloys, etc.
