What's Powder Coating Equipment?

It is just a sort of coating equipment that can help in applying powder. Powder coating equipment doesn't involve solvents rolling around in its processes. The coating is conducted electrostatically which is then passed under heat, allowing the powder to flow and form a "skin". It could be a thermoset polymer or a thermoplastic. Generally, it really is used to provide a hard finish which can be harder than the conventional point which has been formerly used. The principle function of employing this devices are for coating metals, for example bicycle parts, household appliances, aluminium extrusions and others.

Few advantages of powder coating are mentioned below:

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

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

- It Can Be Recycled, Facilitating 100% Reusability Of The Substance  

- Produces More secure Waste As Compared To Traditional Usage of Liquid  

- Part Preparation Or Pre-Treatment  

Ahead of the powder coating process removing lubrication grease, metal oxides, mud, oil etc are very important. There are numerous chemical as well as mechanical ways of removing these substances in the metal surface. The method is dependent upon the performance feature the end product. In spray application, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating of the substrate appear in multiple stage. Bonding with the powder towards the metal involves cleaning within the pre-treatment process. Sand Blasting is an yet another way of preparing the counter ahead of coating. It can be 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 such as abrasive blasting before coating. The internet consumer market typically offers media blasting services coupled with their coating services at additional costs.

Commonly electrostatic gun or corona gun is utilized for utilizing the powder coating to metal objects. Here, lets discuss the working of electrostatic gun. Negative electric charge is imparted on the powder. The negatively charged powder might be sprayed on the grounded object by mechanical or compressed air spraying equipment. It is then accelerated on the workpiece with the powerful electrostatic charge. The thing might be heated, and also the powder melts in to a uniform film, and is also then cooled to make a hard coating. To accomplish more uniform finish preheating could help but problems can also be created as runs due to excess powder.

Tribo gun could be the second form of gun which is used to spray powder on metal surfaces. The powder is first charged by triboelectric friction that charged powder particles then adhere to the grounded substrate. It requires another 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 and then it is dipped into aerated powder-filled bed. Later the powder sticks and melts on the hot object. Most dishwasher racks are coated using this way of [http://people.tribe.net/c98a6bab-1faf-4483-97a7-4b34392f5ae6/blog/5111df34-86ce-432f-9a64-95d0ca0087ef powder coat guns].
