Because LED street lamp is a public goods, need to be exposed to bad weather, light pole is easy to be exposed to surface corrosion, resulting in reduced service life, in order to effectively extend the service life, ensure the use of LED street lamp pole surface oxidation treatment is needed. So, what are the specific antioxidant treatments?
Outdoor LED street lamp surface spray treatment: generally using a length of 60M disposable spray production line, color can be specified by customers, using outdoor polyester plastic powder, plastic layer thickness is greater than 85UM, to ensure curing time, uniform plastic layer, high adhesion, UV irradiation, so lighting LED street lamp pole generally will not peel. There is also a way to use internal and external hot dip galvanized anti-corrosion treatment, zinc layer thickness is greater than 85UM, in line with ZBJ3601-89 standard, not easy to rust.
Another LED street lamp treatment method is powder electrostatic spraying: electrostatic spraying uses the principle of high voltage electrostatic corona electric field. The metal flow guide cup on the nozzle is connected with the high voltage negative electrode, and the coated workpiece is grounded to form a positive electrode, forming a strong electrostatic field between the nozzle and the workpiece. As a carrier gas (air) type powder coatings for powder from the barrel of the powder tube to the spray gun diversion cup, due to the diversion cup have connected to high voltage anode corona discharge, the surrounding dense charge, powder with negative charge, under the action of electrostatic force and compressed air, powder evenly adsorption on the workpiece, the heating, powder melt solidified into a uniform, flat, smooth film. Electrostatic spraying can be divided into spray painting and plastic spraying.
