Pensu bridge

Plastic cable tray is to plastic powder spraying in the cable bridge frame on a surface treatment method.

Don't need to be thinner, construction on the environment pollution-free, harmless to the human body;The coating appearance quality is excellent, strong adhesion and mechanical strength;Spraying construction curing time is short;The coating corrosion resistant ability higher;Don't need primer;Simple construction, low technical requirements for workers;Costs less than painting process;Some construction situation has explicitly put forward must use electrostatic pensu processing,Will not appear in the process of electrostatic powder spraying paint flow process of the common phenomenon.

Is the use of corona discharge phenomenon make the powder coating adsorption in the cable bridge on the shelf.The process goes like this: powder for powder by system by gas into the compressed air spray gun, the gun front with high voltage electrostatic generator of high pressure, due to the corona discharge, near its intensive charge, powder by the gun nozzle jet, the formation of coating of charged particles, it is the role of the electrostatic force, sucked into its opposite polarity artifacts, with spray the powder on the rise, the more charge accumulation, when reaches a certain thickness, because produce electrostatic repulsion, will not continue to adsorption, so that the workpiece to obtain a certain thickness of powder coating, and then after heat to make powder melt and flow flat, curing, namely in the form of hard coating surface.
