Interpretation of the jinan cable tray electrostatic coating of high temperature curing and electrostatic spraying process:
High temperature curing purpose: powder coating on the surface of the workpiece is heated to the specified temperature and heat preservation time, make it melt and flow flat, curing, we want to surface of workpiece is obtained.
Process steps: good spraying workpiece pushed curing furnace, heating to a predetermined temperature (generally 185 degrees c), and heat preservation time (15 minutes); Blowing in remove cooling the finished product.
Tip: heating and control system (including electric heating, fuel, gas, coal and other heating mode) heat preservation box = curing furnace.
Electrostatic spraying purpose: spray powder coating evenly onto the surface of the workpiece, special artifacts (including prone to the location of the electrostatic shielding) high-performance electrostatic spray molding machine should be used to complete the painting.
Process steps: using the electrostatic adsorption principle, on the surface of the workpiece evenly spray a layer of powder coating; After falling powder recovery by recycling system, sieving can be used again.
