Technical Field

[0001] The utility model relates to the technical field of stirring, in particular to a stirring device for producing powder coatings. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigments, fillers and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. Powder coating is divided into two categories: thermoplastic and thermosetting. It is harmless, highly efficient, resource-saving and environmentally friendly. In the production process of powder coating, various raw materials need to be placed in a mixing barrel and stirred to mix the various raw materials evenly.
