It is a type of coating equipment that can help in applying powder. Powder coating equipment does not require solvents in their processes. The coating is completed electrostatically and is then passed under heat, allowing the powder to circulate and form a "skin". It might be a thermoset polymer or possibly a thermoplastic. Generally, it can be accustomed to give a hard finish that is harder compared to conventional point that was formerly used. The main intent behind using this devices are for coating metals, like bicycle parts, household appliances, aluminium profiles and many more.

Few benefits of powder coating are mentioned below:

- It Produces Much Thicker Coating As Compared To Traditional Liquid Coating  

- It may be Recycled, Facilitating 100% Reusability From the Substance  

- Produces More secure Waste In comparison with Traditional Use Of Liquid  

The Powder Coating Equipment operate in following basic processes:

- Part Preparation Or even the Pre-Treatment  

Before the powder coating process removing lubrication grease, metal oxides, mud, oil etc are essential. There are numerous chemical in addition to mechanical strategies to removing these substances from the metal surface. The technique is determined by the performance dependence on the end product. In spray application process, chemical pre-treatments involve using chromates and phosphates. Phosphating and chromating with the substrate exist in multiple stage. Bonding of the powder towards the metal involves cleaning inside the pre-treatment process. Sand Blasting can be an yet another way of preparing the surface ahead of coating. It is used to provide finishing, etching, surface texturing and preparation and degreasing for products made from wood, glass, or plastic. Different powder coating applications can require other methods of preparation like abrasive blasting before coating. The web consumer market typically offers media blasting services in conjunction with their coating services at additional costs.

Commonly electrostatic gun or corona gun can be used for utilizing the powder coating to metal objects. Here, lets discuss the working of electrostatic gun. Negative electric charge is imparted to the powder. The negatively charged powder might be sprayed towards grounded object by mechanical or compressed air spraying equipment. It's then accelerated towards the workpiece with the powerful electrostatic charge. The object will be heated, along with the powder melts in to a uniform film, which is then cooled produce a hard coating. To achieve more uniform finish preheating could help but problems can also be created as runs caused by excess powder.

Tribo gun will be the second kind of gun which is used to spray powder on metal surfaces. The powder is first charged by triboelectric friction that charged powder particles then go through the grounded substrate. It takes some other formulation of powder when it comes to corona guns.

Fluidized bed method may also be used for Powder coating. Initially the substrate is heated and after that it can be dipped into aerated powder-filled bed. Later the powder sticks and melts on the hot object. Most dishwasher racks are coated with this technique of [http://www.migente.com/your_page/blog/view_posting.html?pid=5377910&profile_id=8536291&profile_name=clementjsfs&user_id=8536291&username=clementjsfs powder coating paint].
