About of the plastic powder coating procedures

Powder coating to the process of electrostatic charged particle in a grounded metal project paints and plastics. According to the power of powder coatings, solvent soluble fluorescent toners this technique for the first time in Australia in 1967, producing a smooth, even coating, is more important than the paint and durable. Powder coatings are commonly used in auto parts, animal cage, shelves and other metal objects, you need a can even stand up, moisture and wear coatings. The basic process of the powder coating of metal objects is relatively simple.
Pretreatment
Metal powder coating according to the Group Lootah, you must first remove all the pollutants and dust may prevent adhering to the coating chemical treatment. After treatment, the metal must be completely dry. If the metal coating is thoroughly clean and dry, water or dust trapped in the finished coating can cause problems, thermoplastic fluorescent pigment including the divestiture completed.
Powder application
The power of powder coatings, metal objects must be grounded coat. A charged gun, and then the resin powder a positive electrostatic charge, to encourage it adhere to the object. These particles are similar to the consistency of the copier or laser printer toner. It requires very little powder coating of the object; according to the power of powder coatings, a spoon. An area of about 1 square foot.
Treatment
Once the powder is completely covered to coat an object, put it in a curing oven, plastic powder, melting it into a uniform coating, there is no chance like paint dripping or running. In high temperature curing oven prevent all areas to create a bubble condensate and encourage uniform inflow of powder metal objects. After the baking is completed, about 20 minutes in a sterile environment, shiny, long-lasting, daylight fluorescent pigment for plasticsrequire little maintenance results.
