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.
