ΠΡΟΣΤΑΣΙΑ ΧΑΛΥΒΑ ΑΠΟ ΔΙΑΒΡΩΣΗ

IT HAS BEEN PROVEN THAT STEEL CORROSION FOLLOWS THE MODEL OF WAGNER (GALVANIC ELEMENT). FOR THE PROTECTION OF STEEL FROM CORROSION, ANTICORROSIVE PAINTS CONTAINING PIGMENTS WITH H- SEMICONDUCTIVE PROPERTIES HAVE BEEN USED FOR THE FIRST TIME, AND THUS HAVE DEVELOPED A NEW LINE OF ANTI-CORROSIVE PAINTS. THIS HAS IMPORVED THE ANTICORROSIVE PROPERTIES OF THE ALREADY EXISTING PAINTS (SUCH AS THE COAL TAR EPOXY AND THE CHLORINATED RUBBER), WITH THE USAGE OF H-SEMICONDUCTORS (I.E. Γ-AL2O3, RED MUD, DOPPED OXIDES) OR, INSTEAD OF THE ABOVE, NEW PAINTS USING THE EPOXY AS BASE, HAVE BEEN DEVELOPED. THE PIGMENT CONTENT OF THE VEHICLES, HAS BEEN 30% C.M. THE USAGE OF THE CATHODIC PROTECTION HAS SHOWN THAT IN SEVERAL CASES IT GIVES THE BEST RESULTS FOR STEEL PROTECTION, WHILE WITHOUT ANY CATHODIC PROTECTION, THE BEST RESULTS ARE GIVEN BY THE ADDITION OF THE DOPPED Γ-AL2O3+1% MGO ON EPOXY VEHICLE.
