Advantages of electrostatic sprayingsolar street light-litelsolar manufacturer

The powder coating is sprayed on the surface of the workpiece with electrostatic powder spraying equipment (electrostatic spraying machine). Under the action of static electricity, the powder will be uniformly adsorbed on the surface of the workpiece to form a powder coating; Flat curing, it 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., and the cost is also comparable to the same effect of spraying Down. Process flow Generally, the electrostatic spraying process of metal materials includes pretreatment, electrostatic spraying, high temperature curing, and decorative treatment. The purpose of pre-treatment: to remove oil, dust and rust on the surface of the workpiece, and to form a 'phosphating layer' on the surface of the workpiece that is anti-corrosion and can increase the adhesion of the spray coating. Main 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. of adhesion. Relevant equipment: pretreatment tank (concrete tank, the number is equal to the number of pretreatment steps); related materials (chemicals): sulfuric acid, hydrochloric acid, soda ash (Na2CO3), acid degreaser, phosphating liquid, passivation liquid electrostatic spray Plastic purpose: to spray the powder coating on the surface of the workpiece evenly. 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 recycling system and can be reused after sieving. Relevant materials: powder coating (spraying raw materials, commonly known as 'plastic powderHigh temperature curing purpose: to 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. Tips: heating and control system (including electric heating, fuel oil, gas, coal and other heating methods) + insulation box u003d curing furnace. Relevant equipment: curing furnace (parameters that need to be automatically controlled: temperature, holding time, heating methods can be electric heating, oil heating, gas heating, coal heating, etc., which can be flexibly selected according to the energy situation in your area). Related materials: high temperature curing oven (or oven, oven) that can control temperature and holding time within a reasonable range. The purpose of decoration treatment: to make the workpiece after electrostatic spraying achieve a certain special appearance effect, such as: various wood grains, patterns, brightening and so on. Compared with the traditional spray painting process, the electrostatic spraying process has significant advantages. It does not need thinner materials, and the construction is non-polluting to the environment and non-toxic to the human body; the coating has excellent appearance quality, strong adhesion and mechanical strength; the curing time of spraying construction is short; The corrosion resistance and wear resistance of the coating is much higher; no primer is required; the construction is simple and the technical requirements for workers are low; the cost is lower than the painting process; some construction occasions have clearly stated that the electrostatic spraying process must be used; There will be no flow phenomenon commonly seen in the spray painting process. 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
