It is just a kind of coating equipment that can help in applying powder. Powder coating equipment does not require solvents in their processes. The coating is done electrostatically and it is then passed under heat, allowing the powder circulate and form a "skin". It could be a thermoset polymer or possibly a thermoplastic. Generally, it is employed to provide a hard finish that is harder than the conventional point that was formerly used. The primary function of using this tools are for coating metals, such as bicycle parts, household appliances, aluminium extrusions and many more.

Few benefits of powder coating are mentioned below:

- Emission Of Chemical toxins Are Reduced By Coating The Metals  

- It Produces Much Thicker Coating As Compared To Traditional Liquid Coating  

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

- Produces More reliable Waste As Compared To Traditional Utilization of Liquid  

The Powder Coating Equipment be employed in following basic processes:

- Part Preparation Or even the Pre-Treatment  

Prior to powder coating process elimination of lubrication grease, metal oxides, mud, oil etc are very important. There are several chemical in addition to mechanical ways of removing these substances in the metal surface. The technique is determined by the performance dependence on the end product. In spray application process, chemical pre-treatments involve the use of chromates and phosphates. Phosphating and chromating from the substrate exist in multiple stage. Bonding in the powder towards the metal involves cleaning within the pre-treatment process. Sand Blasting is surely an yet another way of preparing the surface 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 different ways of preparation such as abrasive blasting ahead of coating. The net consumer market typically offers media blasting services coupled with their coating services at additional costs.

Commonly electrostatic gun or corona gun is employed for utilizing 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 grounded object by mechanical or compressed air spraying equipment. It is then accelerated for the workpiece with the powerful electrostatic charge. The thing will be heated, as well as the powder melts in to a uniform film, and is also then cooled to form a hard coating. To accomplish more uniform finish preheating can help you but problems can be created as runs brought on by excess powder.

Tribo gun could be the second kind of gun which is used to spray powder on metal surfaces. The powder is first charged by triboelectric friction which charged powder particles then stick to the grounded substrate. It needs another formulation of powder regarding corona guns.

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