Why do street light poles need electrostatic spraying solar street light-litelsolar manufacturer

The principle of electrostatic spraying process: the powder coating is sprayed on the surface of the workpiece with electrostatic powder spraying equipment (electrostatic spraying machine). After high temperature baking and leveling curing, the layer becomes the final coating with different effects (different types of powder coatings); the spraying effect is better than the spraying process in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., plastic particles It will melt into a dense protective layer and firmly adhere to the surface of the workpiece. The cost is also under the same effect of spray paint. The process flow of electrostatic spraying is pretreatment (degreasing, rust removal, phosphating); electrostatic spraying; high temperature curing (refer to the required temperature of plastic powder, generally 160~210 degrees); cooling after cooling. The advantages of the traditional spray painting process of electrostatic spraying: Compared with the traditional spraying process, the electrostatic spraying process has significant advantages, no thinner materials are required, the construction is non-polluting to the environment, and it is non-toxic to the human body; the coating has excellent appearance quality and adhesion. and strong mechanical strength; short curing time of spraying construction; much higher corrosion resistance and wear resistance of the coating; no primer required; simple construction, low technical requirements for workers; lower cost than spray painting; some construction occasions have clearly stated that it must be used Electrostatic spraying process; electrostatic powder spraying process will not appear the common flow phenomenon in spraying process. Electrostatic spraying process: 1. Pretreatment: remove oil, dust and rust on the surface of the workpiece, and generate a 'phosphating layer' on the surface of the workpiece that is anti-corrosion and can increase the adhesion of the spray coating. Process steps: degreasing, rust removal, phosphating, passivation. After pre-treatment, the workpiece is not only free of oil, rust and dust on the surface, but also a uniform and rough gray phosphating film that is not easy to rust is formed on the original silver-white shiny surface, which can not only prevent rust but also increase the spray layer. 2. Electrostatic spraying: Evenly spray the powder coating on the surface of the workpiece. Special workpieces (including the position where electrostatic shielding is likely to be generated) should be sprayed with a high-performance electrostatic spraying machine. Process steps: Using the principle of electrostatic adsorption, a layer of powder coating is evenly sprayed on the surface of the workpiece; the falling powder is recovered by the recovery system, and can be reused after sieving. 3. High temperature curing: Heat the powder coating on the surface of the workpiece to a specified temperature and keep it for a corresponding time to melt, level and solidify, so as to obtain the desired surface effect of the workpiece. Process steps: Push the sprayed workpiece into the curing furnace, heat it to a predetermined temperature (generally 185 degrees), and keep it for a corresponding time (15 minutes); open the furnace and take it out for cooling to get the finished product. Tip: Heating and control system (including electric heating, fuel oil, gas, coal and other heating methods) + insulation box u003d curing furnace. 4. Decorative treatment: make the workpiece after electrostatic spraying achieve a certain special appearance effect, such as: various wood grains, patterns, brightening and so on. solar street light,solar street light manufacturer,high pole light,high pole light manufacturer,street light,street light manufacturer,street light,street light manufacturer,led street light,led street light manufacturer,street light pole,street light pole manufacturer,landscape light,landscape light manufacturer , Magnolia lanterns, Magnolia lanterns manufacturers, minority street lights Yangzhou Global Solar Technology Development Co., Ltd. is a manufacturer engaged in the production of outdoor road lighting, the main products are city circuit lights, solar street lights, high pole lights, led street lights, all kinds of special-shaped Landscape lights, magnolia lights, Chinese lights, street lights with ethnic characteristics, etc., welcome to visit our factory and consult and discuss business cooperation
