It is a type of coating equipment that helps in applying powder. Powder coating equipment doesn't require solvents in the processes. The coating is carried out electrostatically and is also then passed under heat, allowing the powder circulation and form a "skin". It may be a thermoset polymer or perhaps a thermoplastic. Generally, it really is utilized to offer a hard finish which is harder compared to the conventional point that was formerly used. The primary reason for applying this products are for coating metals, for example bicycle parts, household appliances, aluminium profiles and many more.

Few advantages of powder coating are mentioned below:

- Emission Of Chemical toxins Are Reduced By Coating The Metals  

- It makes Much Thicker Coating In comparison with Traditional Liquid Coating  

- It is usually Recycled, Facilitating 100% Reusability With the Substance  

- Produces More secure Waste As Compared To Traditional Using Liquid  

Technique of Powder Coating

The Powder Coating Equipment be employed in following basic processes:

Prior to the powder coating process removal of lubrication grease, metal oxides, mud, oil etc are very important. There are numerous chemical in addition to mechanical ways of removing these substances from your metal surface. The process will depend on the performance requirement of the finished product. In spray application process, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating of the substrate appear in multiple stage. Bonding in the powder to the metal involves cleaning inside the pre-treatment process. Sand Blasting is surely an another method of preparing the top prior to coating. It can be utilized to provide finishing, etching, surface texturing and preparation and degreasing for products made of wood, glass, or plastic. Different powder coating applications can require other methods of preparation such as abrasive blasting prior to coating. The web consumer market typically offers media blasting services coupled with their coating services at additional costs.

Commonly electrostatic gun or corona gun can be used for applying the powder coating to metal objects. Here, lets discuss the working of electrostatic gun. Negative electric charge is imparted towards the powder. The negatively charged powder is then sprayed towards the grounded object by mechanical or compressed air spraying equipment. This will make it accelerated towards the workpiece through the powerful electrostatic charge. The item will then be heated, and the powder melts right into a uniform film, and it is then cooled to create a hard coating. To attain more uniform finish preheating could help but problems can also be created as runs brought on by excess powder.

Tribo gun may be the second kind of gun utilized to spray powder on metal surfaces. The powder is first charged by triboelectric friction and the charged powder particles then adhere to the grounded substrate. It requires an alternative formulation of powder when it comes to corona guns.

Fluidized bed method may also be used for Powder coating. In the beginning the substrate is heated then it really is dipped into aerated powder-filled bed. Later the powder sticks and melts towards the hot object. Most dishwasher racks are coated with this method of [http://people.tribe.net/c98a6bab-1faf-4483-97a7-4b34392f5ae6/blog/5111df34-86ce-432f-9a64-95d0ca0087ef powder coating supplies].
