Plastic tray

Plastic cable bridge is a surface treatment method of plastic powder coating on the cable tray.

Does not need to be thinner, construction on the environment pollution-free, on the human body no poison; appearance of the coating quality is excellent, strong adhesion and mechanical strength; spraying curing time is short; coating corrosion resistant ability of much higher; primer; simple construction of technical workers requiring low; low cost in painting process, some construction sites has been clearly put forward must deal with the use of electrostatic spray process; electrostatic powder spraying process does not appear in the painting process in common flow phenomenon.

Is the use of corona discharge phenomenon of powder coatings adsorbed on the cable tray on. The process is this: powder coating by powder supply system by compressed air into the gas gun, a high voltage of the high-voltage electrostatic generator in the gun front, due to the corona discharge, producing a dense charge in its vicinity by powder spout gun, the formation of charged coating particles, it is affected by the electrostatic force, being sucked with the opposite polarity to the workpiece, with the spray powder increased, the charge accumulation is more also, when reaches a certain thickness, due to electrostatic repulsion, will not continue to adsorption, the powder coating so that the workpiece thickness, and then through the heat of the powder melting, leveling, curing, forming the hard coating on the surface of the workpiece.
