What's Powder Coating Equipment?

It is a type of coating equipment which enables in applying powder. Powder coating equipment does not involve solvents in the processes. The coating is carried out electrostatically and 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's accustomed to give you a hard finish which can be harder compared to conventional point which has been formerly used. The primary reason for using this products are for coating metals, for example bicycle parts, household appliances, aluminium profiles and many more.

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

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

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

- Produces Better Waste As compared with Traditional Utilization of Liquid  

Process Of Powder Coating

The Powder Coating Equipment operate in following basic processes:

Prior to powder coating process elimination of lubrication grease, metal oxides, mud, oil etc are essential. There are numerous chemical and also mechanical types of removing these substances from the metal surface. The process depends upon the performance feature the finished product. In spray application process, chemical pre-treatments involve using chromates and phosphates. Phosphating and chromating from the substrate appear in multiple stage. Bonding in the powder towards the metal involves cleaning within the pre-treatment process. Sand Blasting is an another method of preparing the outer lining prior to coating. It really is used to provide finishing, etching, surface texturing and preparation and degreasing for products manufactured from wood, glass, or plastic. Different powder coating applications can require various ways of preparation including abrasive blasting just before coating. The net consumer market typically offers media blasting services along 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 significant of electrostatic gun. Negative electric charge is imparted towards the powder. The negatively charged powder will be sprayed on the grounded object by mechanical or compressed air spraying equipment. Then it is accelerated towards the workpiece from the powerful electrostatic charge. The thing will be heated, and the powder melts into a uniform film, and is then cooled produce a hard coating. To achieve more uniform finish preheating might help but problems can even be created as runs a result of excess powder.

Tribo gun could be the second form 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 needs another formulation of powder with regards to corona guns.

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