Powder coated cable tray is a surface treatment method of spraying plastic powder on the cable tray.
No thinner is required, the construction will not pollute the environment and will not harm the human body; The coating has excellent appearance quality, strong adhesion and mechanical strength; The curing time of spraying construction is short; The corrosion and wear resistance of the coating is much higher; No primer is required; Simple construction and low technical requirements for workers; The cost is lower than the painting process; In some construction sites, it has been clearly pointed out that electrostatic spraying process must be used; There will be no common flow phenomenon in the process of electrostatic powder spraying.
The powder coating is adsorbed on the cable tray by corona discharge. The process is as follows: the powder coating is sent to the spray gun by the powder supply system through the compressed air gas. The high voltage generated by the high-voltage electrostatic generator is added at the front end of the spray gun. Due to corona discharge, dense charges are generated near the spray gun. When the powder is ejected from the nozzle, charged coating particles are formed. It is attracted to the workpiece with opposite polarity by the electrostatic force. With the increase of the sprayed powder, the charge accumulates more, When a certain thickness is reached, the electrostatic repulsion will not continue to absorb, so that the whole workpiece can obtain a certain thickness of powder coating, and then the powder is melted, leveled and solidified by heat, that is, a hard coating film is formed on the surface of the workpiece.
The channel type cable tray is also called the trough type cable tray. It is a fully enclosed cable tray. It is most suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has a good effect on shielding interference of control cables and protection of cables in heavy corrosive environment.
