This is a type of coating equipment that can help in applying powder. Powder coating equipment does not involve solvents in their processes. The coating is conducted electrostatically and is then passed under heat, allowing the powder circulate and form a "skin". It may be a thermoset polymer or a thermoplastic. Generally, it is accustomed to give you a hard finish which is harder than the conventional point which was formerly used. The key reason for applying this equipment is for coating metals, including bicycle parts, household appliances, aluminium planks and others.

Few attributes of powder coating are mentioned below:

- It makes Much Thicker Coating When compared with Traditional Liquid Coating  

- It could be Recycled, Facilitating 100% Reusability With the Substance  

- Produces Better Waste As compared with Traditional Usage of Liquid  

Means of Powder Coating

The Powder Coating Equipment operate in following basic processes:

- Part Preparation Or perhaps the Pre-Treatment  

Before the powder coating process removing lubrication grease, metal oxides, mud, oil etc are crucial. There are several chemical as well as mechanical strategies to removing these substances from your metal surface. The process depends upon the performance requirement of the end product. In spray application process, chemical pre-treatments involve the use of chromates and phosphates. Phosphating and chromating with the substrate appear in multiple stage. Bonding in the powder for the metal involves cleaning from the pre-treatment process. Sand Blasting can be an another method of preparing the surface just before coating. It is employed to provide finishing, etching, surface texturing and preparation and degreasing for products made of wood, glass, or plastic. Different powder coating applications can require various ways of preparation including abrasive blasting before coating. The net consumer market typically offers media blasting services coupled with their coating services at additional costs.

Commonly electrostatic gun or corona gun is used for utilizing the powder coating to metal objects. Here, lets discuss the significant of electrostatic gun. Negative electric charge is imparted for the powder. The negatively charged powder is then sprayed towards grounded object by mechanical or compressed air spraying equipment. Then it is accelerated on the workpiece through the powerful electrostatic charge. The object is then heated, as well as the powder melts into a uniform film, and it is then cooled produce a hard coating. To achieve more uniform finish preheating could help but problems can even be created as runs a result of excess powder.

Tribo gun will be the second form of gun which is often used to spray powder on metal surfaces. The powder is first charged by triboelectric friction and these charged powder particles then follow the grounded substrate. It needs another formulation of powder when it comes to corona guns.

Fluidized bed method may also be used for Powder coating. At first the substrate is heated and then it can be dipped into aerated powder-filled bed. Later the powder sticks and melts towards the hot object. Most dishwasher racks are coated using this technique of [http://fredgkbd.deviantart.com/journal/Powder-Coating-Can-Be-A-Revolutionary-471359735 powder coating supplies].
