What Is Powder Coating Equipment?

It is a type of coating equipment which enables in applying powder. Powder coating equipment does not involve solvents in their processes. The coating is carried out electrostatically and is then passed under heat, allowing the powder to flow and form a "skin". It can be a thermoset polymer or a thermoplastic. Generally, it's employed to give you a hard finish that's harder as opposed to conventional point which was formerly used. The key purpose of using this products are for coating metals, like bicycle parts, household appliances, pool enclosures and more.

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 When compared with Traditional Liquid Coating 
- It is usually Recycled, Facilitating 100% Reusability Of The Substance 
- Produces More reliable Waste In comparison with Traditional Usage of Liquid 
- Lesser Operating Cost Than Liquid Lines

Technique of Powder Coating

The Powder Coating Equipment be employed in following basic processes:

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

Processes And Equipment Of Part Preparation

Prior to powder coating process removing lubrication grease, metal oxides, mud, oil etc are crucial. There are numerous chemical in addition to mechanical types of removing these substances from the metal surface. The method is dependent upon the performance requirement of the end product. In spray application, chemical pre-treatments involve the usage of chromates and phosphates. Phosphating and chromating from the substrate occur in multiple stage. Bonding with the powder on the metal involves cleaning within the pre-treatment process. Sand Blasting is surely an yet another way of preparing the outer lining before coating. It can be utilized to provide finishing, etching, surface texturing and preparation and degreasing for products made of wood, glass, or plastic. Different powder coating applications can require different ways of preparation such as abrasive blasting just before coating. The web consumer market typically offers media blasting services coupled with their coating services at additional costs.

Commonly electrostatic gun or corona gun can be used for applying 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 will then be sprayed for the grounded object by mechanical or compressed air spraying equipment. It's then accelerated on the workpiece through the powerful electrostatic charge. The item will be heated, and also the powder melts in to a uniform film, and it is then cooled to create a hard coating. To attain more uniform finish preheating might help but problems may also be created as runs caused by excess powder.

Tribo gun could be the second sort of gun that is utilized to spray powder on metal surfaces. The powder is first charged by triboelectric friction and the charged powder particles then stick to the grounded substrate. It requires a different formulation of powder when it comes to corona guns.

Fluidized bed method may also be used for Powder coating. At first the substrate is heated after which it really is dipped into aerated powder-filled bed. Later the powder sticks and melts to the hot object. Most dishwasher racks are coated with this particular method of [http://quizilla.teennick.com/stories/24413001 powder coating equipment].
