Technical Field

[0001] The utility model belongs to the technical field of fluorocarbon powder coating processing, in particular to a separation and screening device for producing fluorocarbon powder coating. Background Art

[0002] Fluorocarbon powder coating refers to a coating with fluororesin as the main film-forming substance; it is also called fluorocarbon paint, fluorine coating, fluororesin coating, etc. Among various coatings, fluororesin coating has particularly superior properties due to the large electronegativity of the introduced fluorine element and the strong carbon-fluorine bond energy.

[0003] After the processing of fluorocarbon powder coatings is completed, in order to make the size of fluorocarbon powder coatings more uniform, the fluorocarbon powder coatings need to be screened, so a corresponding separation and screening device for fluorocarbon powder coating production is needed.

After searching, the patent document with the authorization announcement number of CN220635238U discloses a separation and screening device for fluorocarbon powder coating production, which also has such problems in actual use.
