The invention relates to the technical field of
coating, and discloses a
powder-spraying and paint-spraying single-line spray
system. The
powder-spraying and paint-spraying single-line spray
system comprises a gluing chamber, a
colored paint spraying chamber, a leveling chamber I, a clear
lacquer spraying chamber, a leveling chamber II and a
drying chamber, which are sequentially arranged, and further comprises a mobile
powder room, wherein an opening for allowing the mobile powder room to get in and get out is formed in the leveling chamber II; and an opening-closing device is corresponding to the opening. The
system can realize powder-spraying and paint-spraying on a single
production line. In the meantime of achieving advantages of zero VOC emission and
low input of powder spraying, requirements for spraying in different colors for work pieces can be met conveniently by utilizing an
advantage that multi-color spraying can be realized by utilizing paint spraying, and the cost is reduced. The invention further provides a powder-spraying process and a paint-spraying process. The powder-spraying process comprises the steps of gluing, carrying out powder-spraying pretreatment, carrying out powder-spraying,
drying and the like; and the paint-spraying process comprises the steps of gluing, spraying
colored paint, carrying out primary leveling, spraying clear
lacquer, carrying out secondary leveling,
drying and the like. The powder-spraying process and the paint-spraying process can be carried out on the same
production line, and are convenient in
coating.
