弱酸电解除锈方法;ELECTROLYTIC METHOD FOR REMOVING RUST BY USING WEAK ACID

摘要

本发明系有关于一种弱酸电解除锈方法，其步骤包括：提供一表面含有锈皮之钢材，其中钢材可例如为含铁合金钢或不锈钢或碳钢；接着，使表面含有锈皮之钢材作为阳极，再置入一含有顺丁烯二酸离子之弱酸电解液中进行电解处理；然后，施予一外力于表面含有锈皮之钢材，使锈皮自钢材之表面脱离而除锈完成，并制得一表面无锈皮之钢材；藉此，可得到一具有平滑且光亮表面之钢材。; using the steel material to be an anode and putting it in a weak acidic electrolyte containing maleic acid ions for conducting electrolysis; applying an external force to the steel material until rust is peeled off from the steel material and thus a steel material without rust thereon can be obtained. Accordingly, the present method can manufacture a steel material having a smooth and shiny surface thereof.
