Ion exchange resin used in solid electrolytic polishing of metal workpieces and use method thereof

Abstract

The present disclosure relates to an ion exchange resin used in solid electrolytic polishing of metal workpieces and a use method thereof. The ion exchange resin is an organic weak acid-type cation exchange resin with a porous structure; and the ion exchange resin contains an electrolyte inside pores and/or on the surface of the ion exchange resin. The ion exchange resin is used in solid electrolytic polishing of a metal workpiece. Compared to mechanical polishing and electrolytic polishing, the ion exchange resin can fully polish parts that are not easily accessible for grinding. The method does not require a large amount of chemical oxidizing agents and electrolytes during polishing, thus being environmentally friendly and highly safe. In addition, the modified ion exchange resin can be regenerated after a period of use, greatly increasing the service life and reducing costs.
