Abstract

Et enkelt anodesystem brukt i flere elektrokjemiske behandlinger for å kontrollere stålkorrosjon i betong innbefatter et offermetall som er i stand til å støtte høyt påtrykte anodestrømtettheter med en koblingsdetalj for påtrykt strømanode og et porøst innebyggende materiale som inneholder en elektrolytt. Initielt er strøm drevet fra offermetallet [1] til stålet [10] ved å bruke en kraftkilde [5] som konverterer oksygen og vann [14] til hydroksylioner [15] på stålet og trekkende kloridioner [16] inn i det porøse materialet [2] rundt anoden slik at de korroderende områdene er flyttet fra stålet til anoden som gjenoppretter stålpassiviteten og aktiverer anoden. Katodisk forebygging er deretter anvendt. Dette er fortrinnsvis påtrykt katodisk forebygging som er anvendt ved å frakoble strømkilden og tilkoble den aktiverte offeranoden direkte på stålet.A single anode system used in several electrochemical treatments to control steel corrosion in concrete includes a sacrificial metal capable of supporting high-pressure anode current densities with a coupling detail for applied current anode and a porous embedded material containing an electrolyte. Initially, current is driven from the sacrificial metal [1] to the steel [10] using a power source [5] which converts oxygen and water [14] to hydroxyl ions [15] on the steel and drawing chloride ions [16] into the porous material [2 ] around the anode so that the corrosive areas are moved from the steel to the anode which restores the steel passivity and activates the anode. Cathodic prevention is then applied. This is preferably applied to cathodic prevention which is used by disconnecting the power source and connecting the activated sacrificial anode directly to the steel.
