It's a type of coating equipment that can help in applying powder. Powder coating equipment doesn't require solvents in their processes. The coating is done electrostatically and is then passed under heat, allowing the powder circulate and form a "skin". It can be a thermoset polymer or possibly a thermoplastic. Generally, it's employed to give a hard finish which can be harder compared to conventional point which was formerly used. The primary function of applying this products are for coating metals, including bicycle parts, household appliances, aluminium profiles and others.

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

- It creates Much Thicker Coating As compared with Traditional Liquid Coating  

- Produces Less Hazardous Waste In comparison with Traditional Usage of Liquid  

Procedure for Powder Coating

- Part Preparation Or The Pre-Treatment  

Ahead of the powder coating process removal of lubrication grease, metal oxides, mud, oil etc are essential. There are numerous chemical along with mechanical strategies to removing these substances in the metal surface. The technique will depend on the performance requirement of the finished product. In spray application process, chemical pre-treatments involve the use of chromates and phosphates. Phosphating and chromating in the substrate happen in multiple stage. Bonding in the powder towards the metal involves cleaning within the pre-treatment process. Sand Blasting is definitely an yet another way of preparing the counter just before coating. It can be used to provide finishing, etching, surface texturing and preparation and degreasing for products created from wood, glass, or plastic. Different powder coating applications can require alternative methods of preparation for example abrasive blasting ahead of coating. The internet 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 using the powder coating to metal objects. Here, lets discuss the significant of electrostatic gun. Negative electric charge is imparted to the powder. The negatively charged powder might be sprayed towards the grounded object by mechanical or compressed air spraying equipment. It's then accelerated for the workpiece with the powerful electrostatic charge. The thing will then be heated, as well as the powder melts right into a uniform film, and it is then cooled to form a hard coating. To attain more uniform finish preheating may help but problems can even be created as runs brought on by excess powder.

Tribo gun will be the second kind 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 follow the grounded substrate. It needs another formulation of powder regarding corona guns.

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