COATING PRODUCTION LINE
This production line is mainly used for the surface treatment of aluminum fins (aluminum foil) of air conditioner heat exchangers, making it have excellent corrosion resistance, self-lubricating ability and excellent hydrophilic performance.
This production line adopts the continuous production technology of double loading and unwinding, double winding and unwinding, double-sided coating and double-sided curing.
Coating process flow chart
Double roll-up → coating pretreatment (immersion lye degreasing) → spraying lye degreasing → immersion and spray cleaning → small oven drying → air quenching, water drum quenching (including traction device) → double-sided bottom Coating (antioxidant corrosion coating treatment) → curing and drying → air quenching, water drum quenching (including tension detection) → double-sided top coating (hydrophilic coating treatment) → curing and drying → air quenching → water drum quenching → main Traction → double coil take-off and unload
