It's a sort of coating equipment that can help in applying powder. Powder coating equipment doesn't involve solvents in their processes. The coating is done electrostatically and it is then passed under heat, allowing the powder to circulate and form a "skin". It could be a thermoset polymer or a thermoplastic. Generally, it is employed to give a hard finish which can be harder than the conventional point that has been formerly used. The main intent behind applying this products are for coating metals, including bicycle parts, household appliances, aluminium planks and others.

- Emission Of Volatile Organic Compounds Are Reduced By Coating The Metals  

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

- It could be Recycled, Facilitating 100% Reusability Of The Substance  

- Produces Less Hazardous Waste As Compared To Traditional Usage of Liquid  

Technique of Powder Coating

The Powder Coating Equipment operate in following basic processes:

- Part Preparation Or The Pre-Treatment  

Before the powder coating process elimination of lubrication grease, metal oxides, mud, oil etc are necessary. There are many chemical and also mechanical ways of removing these substances in the metal surface. The strategy is determined by the performance dependence on the finished product. In spray application process, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating from the substrate happen in multiple stage. Bonding from the powder towards the metal involves cleaning in the pre-treatment process. Sand Blasting is surely an permanently of preparing the outer lining prior to coating. It's accustomed to provide finishing, etching, surface texturing and preparation and degreasing for products made from wood, glass, or plastic. Different powder coating applications can require alternative methods of preparation for example 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 is employed for applying 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 will then be sprayed towards the grounded object by mechanical or compressed air spraying equipment. It is then accelerated for the workpiece by the powerful electrostatic charge. The thing will be heated, along with the powder melts right into a uniform film, and is also then cooled to form a hard coating. To accomplish more uniform finish preheating could help but problems may also be created as runs brought on by excess powder.

Tribo gun will be the second sort of gun utilized to spray powder on metal surfaces. The powder is first charged by triboelectric friction and these charged powder particles then go through the grounded substrate. It requires another formulation of powder with respect to corona guns.

Fluidized bed method can also be used for Powder coating. Initially the substrate is heated after which it really is dipped into aerated powder-filled bed. Later the powder sticks and melts on the hot object. Most dishwasher racks are coated with this particular technique of [http://people.tribe.net/277d20cf-3a72-43bf-9a86-d19d34328dd5/blog/40a0ab48-bf2a-4644-9180-487bb409f801 powder coating supplies].
