the plastic powder coating on the part of the kinds of surface treatment.
Edit this paragraph spraying process (electrostatic spray) has the advantages: no rare materials,
monster beats by dr. dre, construction on the environment pollution-free, non-toxic to humans; coating appearance of excellent quality, strong adhesion and mechanical strength; spray curing time short; corrosion resistant coatings are much higher capacity; without primer; construction of simple, low technical requirements for workers; cost less than the painting process; some occasions, the construction has made it clear that it is necessary to use electrostatic spray Process; electrostatic duster spray painting process does not occur during the flow in the common phenomenon.

electrostatic spray process principle: is the use of corona discharge phenomena adsorbed on the powder coating on the workpiece. The process is this: powder for powder coating systems, by compressed air from the gas into the gun, the gun plus a front-end high-voltage electrostatic generator, the corona discharge, generated in the vicinity of the charge density, the powder from the spray gun with a muzzle, the formation of charged paint particles,
beats by dre studio, it is the role of static electricity, was sucked up the workpiece with its polar opposite, with the sprayed powder increased, the more charge accumulation, when a certain thickness,
lady gaga heartbeats, since electrostatic repulsion, they will not continue to adsorption,
monster beats headphones, so that the entire workpiece to obtain a certain thickness of the powder coating, and then through the heat melting the powder, leveling, curing, that is to form a hard surface coating. Edit this paragraph
electrostatic spray process: 1, pre-treatment:
Objective: To get rid of surface oils, dirt, rust and corrosion-resistant surface layer and can generate increased spray coating adhesion of the
main process steps: degreasing, rust, phosphate, passivation. Workpiece surface before the treatment is not only oil, rust, dust, and the original silver-white glossy surface generate a uniform is not easy to rust and rough gray phosphate coating, spray layer can increase both rust adhesion
2, electrostatic spraying
Objective: The powder coating evenly sprayed to the workpiece surface, a special piece (including static shielding prone position) should be high-performance electrostatic spray machine to complete the spraying.
process steps:
using electrostatic adsorption principle, the surface of the workpiece sprayed a layer of powder coating;
powder falling through the recovery system recovery, sieved can be reused
3, high temperature curing
Purpose: the surface of the powder coating is heated to the required temperature and holding the appropriate time, so melting, leveling,
heartbeats by lady gaga, curing, resulting in our the desired surface effects.
process steps: the good parts into the cured coating furnace, heated to a predetermined temperature (usually 185 degrees), and holding the appropriate time (15 minutes); furnace cooling is to be finished out.
Tip: heating and control systems (including electric heating, oil, gas, coal and other heating methods) + box = heat curing oven.

beats by dr dre studio, decorative treatment:
Purpose: To enable the workpiece by electrostatic spray after the special appearance to a certain effect, such as: all kinds of wood, patterns, lightening and so on.
process steps: Clear; transfer, and treatment process
spray is what we often talk about the electrostatic powder coating, which is used to make plastic powder electrostatic generator charged, adsorbed on iron surface, then after 180 ~ 220 ℃ baking, melt the powder adhesion to the metal surface, spray products used for indoor use of the box, the film presents plain or matte finish. There are acrylic powder spray powder, polyester powder and so on.
