Teflon coating production line is mainly applied for kitchen utensils industry, such as non-stick pan, rice cooker pot, knives, baking pan, and so on. The main process: sandblasting pre-treatment → blowing dust → base coat → curing → top coat → curing → cooling → unload.
Coating production line main parts
The main components of coating line include: pretreatment equipment, painting equipment, heating and curing furnace, heat source system, electric control system, conveyor and so on.
The pre-treatment:
Purpose: Remove oil on workpiece and produce a layer of corrosion resistance
The main process steps: degreasing, rust removal, phosphate, passivation.
Related equipment: pretreatment bad. Related materials (chemicals) sulfuric acid, hydrochloric acid, soda ash, acid degreasing agent, phosphating solution, passivation solution.
The automatic spraying production line includes a self-priming three-curtain environment-friendly dust-free spray booth, a dust-free spray booth with a standard automatic surface coating, a set of automatic blowing dust system, a 60℃ preheating system, a set base coat curing bake furnace, a set of 28M-1200MM-420℃ type high temperature curing bake furnace.
Temperature control: high-temperature furnace has three temperature zone - heating zone, heat preservation zone and cooling zone three sections, heat preservation zone provides 380-420 ℃ for 12 minutes.
Workflow:
Load --- Passive preheating area (before leveling - preheating evaporation) --- high temperature sintering zone --- passive energy-saving insulation zone --- buffer --- quench zone --- Export hand under the pieces
