Electrostatic powder spraying process and related materials

electrostatic spray molding process principle: with electrostatic spray coating equipment (electrostatic spray machine) powder coating to the surface of the workpiece, under static action, the powder will be evenly adsorbed to the surface of the workpiece, forming a powder-like coating;1, pre-treatmentprocess: de-oil, rust removal, phosphating, passivationAfter pre-treatment, not only the surface without oil, rust, dust, and the original silver-white shiny surface to produce a uniform and rough not easy to rust the gray phosphating film, both rust-proof and increase the adhesion of the spray layerrelated equipment and raw materials: pretreatment tank (concrete tank);2, electrostatic sprayingprocess: the surface of the workpiece using electrostatic adsorption principle uniform spray on a layer of powder, falling powder through the recycling system recycling, after screening can be reusedrelated equipment and raw materials: electrostatic spray machine (electrostatic powder sprayer), powder recovery system, powder coating3, high temperature curingprocess: the sprayed workpiece into the oven, heat to a predetermined temperature (generally 185 degrees), and keep warm the corresponding time (15 minutes);related equipment and raw materials: curing furnace (temperature control, time control);4, decoration treatmentprocess: electrostatic spraying of the workpiece in order to achieve a certain appearance effect such as: a variety of wood grain, such as the process taken(covering light; transfer, etc.)
