It is a kind of coating equipment that assists in applying powder. Powder coating equipment doesn't require solvents in its processes. The coating is conducted electrostatically and is also then passed under heat, allowing the powder to circulate and form a "skin". It can be a thermoset polymer or perhaps a thermoplastic. Generally, it's employed to give you a hard finish which is harder as opposed to conventional point which has been formerly used. The principle reason for using this equipment is for coating metals, for example bicycle parts, household appliances, pool enclosures and others.

Few advantages of powder coating are mentioned below:

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

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

- Produces Better Waste When compared with Traditional Usage of Liquid  

Process Of Powder Coating

The Powder Coating Equipment work in following basic processes:

Ahead of the powder coating process removal of lubrication grease, metal oxides, mud, oil etc are essential. There are various chemical in addition to mechanical ways of removing these substances from the metal surface. The method depends upon the performance requirement of the end product. In spray application process, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating of the substrate exist in multiple stage. Bonding of the powder on the metal involves cleaning inside the pre-treatment process. Sand Blasting is an yet another way of preparing the counter prior to coating. It really is employed to provide finishing, etching, surface texturing and preparation and degreasing for products manufactured from wood, glass, or plastic. Different powder coating applications can require other methods of preparation for example abrasive blasting prior to coating. The online consumer market typically offers media blasting services along with their coating services at additional costs.

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

Tribo gun is the second sort of gun which is often 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 an alternative formulation of powder with regards to corona guns.

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