Title:
PRODUCTION METHOD FOR CROSSLINKED FLUORINE RESIN COATING PUMP ROTOR, CROSSLINKED FLUORINE RESIN COATING PUMP ROTOR, PRODUCTION METHOD FOR CROSSLINKED FLUORINE RESIN COATING PUMP COVER, AND CROSSLINKED FLUORINE RESIN COATING PUMP COVER
Document Type and Number:
WIPO Patent Application WO/2021/130863
Kind Code:
A1
Abstract:
A method for producing a crosslinked fluorine resin coating pump rotor having a flat rotor lateral surface, and being provided with a coating layer of a crosslinked fluorine resin on the rotor lateral surface, the method comprising: screen-printing a liquid dispersion in which particles of a fluorine resin are dispersed in a solvent, on the rotor lateral surface, using a screen plate having an opening shaped so that the opening does not extend off an outer peripheral edge of the rotor lateral surface; thereafter, heating the pump rotor to a temperature equal to or higher than the melting point of the fluorine resin to bake the fluorine resin of the rotor lateral surface; and thereafter, irradiating the fluorine resin with radiation to crosslink the fluorine resin.
