Precisely what is Powder Coating Equipment?

It is just a type of coating equipment that helps in applying powder. Powder coating equipment does not require solvents in their 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 even a thermoplastic. Generally, it is employed to offer a hard finish which is harder compared to conventional point that was formerly used. The principle reason for using this products are for coating metals, for example bicycle parts, household appliances, pool enclosures and others.

Advantages

Few advantages of powder coating are mentioned below:

- Emission Of Volatile Organic Compounds Are Reduced By Coating The Metals 
- It creates Much Thicker Coating As compared with Traditional Liquid Coating 
- It Can Be Recycled, Facilitating 100% Reusability In the Substance 
- Produces More secure Waste In comparison with Traditional Utilization of Liquid 
- Lesser Operating Cost Than Liquid Lines

Means of Powder Coating

The Powder Coating Equipment are employed in following basic processes:

- Part Preparation Or perhaps the Pre-Treatment 
- The Powder Application 
- Curing

Processes And Equipment Of Part Preparation

Before the powder coating process eliminating lubrication grease, metal oxides, mud, oil etc are crucial. There are several chemical in addition to mechanical ways of removing these substances in the metal surface. The method depends upon the performance feature the end product. In spray application process, chemical pre-treatments involve using chromates and phosphates. Phosphating and chromating with the substrate happen in multiple stage. Bonding of the powder towards the metal involves cleaning within the pre-treatment process. Sand Blasting is an yet another way of preparing the counter prior to coating. It's utilized 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 like abrasive blasting prior to coating. The online 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 for the powder. The negatively charged powder is then sprayed on the grounded object by mechanical or compressed air spraying equipment. Then it is accelerated towards workpiece by the powerful electrostatic charge. The article will be heated, along with the powder melts in to a uniform film, which is then cooled to make a hard coating. To accomplish more uniform finish preheating might help but problems can also be created as runs a result of excess powder.

Tribo gun could be the second sort of gun which is used to spray powder on metal surfaces. The powder is first charged by triboelectric friction which charged powder particles then follow the grounded substrate. It will take a different formulation of powder with regards to corona guns.

Fluidized bed method could also be used for Powder coating. In the beginning the substrate is heated and after that it can be dipped into aerated powder-filled bed. Later the powder sticks and melts towards the hot object.
