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.

Abstract: A starter for an internal combustion engine includes an electric motor and a solenoid switch. The solenoid switch includes a housing, a fixed core, a movable core, two spaced contacts, and a conductive member arranged to interconnect the contacts when the solenoid is turned on. The movable core is connected to a pinion of the motor which is movable to engage with a flywheel of the engine. The fixed core includes a pull-in coil of aluminum wire, a holding coil of copper wire, and a magnetic core. The motor is connected in series with the pull-in coil. When the solenoid is energized, the coils generate a magnetic field that attracts the movable core to the magnetic core, thereby the moving the pinion into engagement with the flywheel and causing the conductive member to interconnect the contacts.
