The preparation process of the lamellar pigments for anticorrosive coatings obtained from scale of carbon steels and low alloy and process for preparing the ink with the same pigments.

摘要

It is described a process for preparation of pigments or fillers, lamellar iron oxide, hematite and magnetite obtained more specifically of lamellar slag carbon steels and low alloyed steels for use in the manufacture of anticorrosion paint from steel production, C As those formed by thermal oxidation on the casting, forging and reheating of ingots.As in heat treatment and rolling and profile extrusion plans and no plans or other parts of these steels. This scale can be collected by collectors in channels or during pickling rolling mills which precedes the mechanical drawing.The lamellar loads obtained as described in this invention, to replace the micaceous oxide of mineral origin and those obtained by chemical precipitation, which are currently used as pigments in the industry of production of paints, primers, adhesives, sealants or any other type of re Dress or pre treatment, organic or inorganic,Blocking the permeation of corrosive agents through the coating and can be used in the prevention of corrosion of metallic substrates. The invention described adds value to the solid residue undesirable consisting of Russeting and produced on a large scale in steel production, reducing environmental impact and increasing the protective properties of anticorrosion coatings.
