What Is Powder Coating Equipment?

It is just a sort of coating equipment which enables in applying powder. Powder coating equipment doesn't require solvents in its processes. The coating is completed electrostatically and is also then passed under heat, allowing the powder circulation and form a "skin". It can be a thermoset polymer or even a thermoplastic. Generally, it's utilized to give a hard finish which can be harder than the conventional point that was formerly used. The primary intent behind applying this tools are for coating metals, for example bicycle parts, household appliances, aluminium planks and more.

Advantages

Few benefits of powder coating are mentioned below:

- Emission Of Volatile Organic Compounds Are Reduced By Coating The Metals 
- It Produces Much Thicker Coating When compared with Traditional Liquid Coating 
- It Can Be Recycled, Facilitating 100% Reusability Of The Substance 
- Produces More reliable Waste When compared with Traditional Using Liquid 
- Lesser Operating Cost Than Liquid Lines

Process 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

Prior to the powder coating process removing lubrication grease, metal oxides, mud, oil etc are very important. There are many chemical along with mechanical ways of removing these substances from your metal surface. The method is dependent upon the performance requirement of the finished product. In spray application process, chemical pre-treatments involve the application of chromates and phosphates. Phosphating and chromating in the substrate appear in multiple stage. Bonding with the powder on the metal involves cleaning inside the pre-treatment process. Sand Blasting is an yet another way of preparing the surface prior to coating. It really is employed to provide finishing, etching, surface texturing and preparation and degreasing for products manufactured from wood, glass, or plastic. Different powder coating applications can require alternative methods of preparation for example abrasive blasting ahead of coating. The net consumer market typically offers media blasting services in conjunction with their coating services at additional costs.

Commonly electrostatic gun or corona gun is employed for applying the powder coating to metal objects. Here, lets discuss the running of electrostatic gun. Negative electric charge is imparted on the powder. The negatively charged powder will then be sprayed towards the grounded object by mechanical or compressed air spraying equipment. It's then accelerated on the workpiece from the powerful electrostatic charge. The item will then be heated, and the powder melts in to a uniform film, which is then cooled to make a hard coating. To achieve more uniform finish preheating might help but problems can be created as runs due to excess powder.

Tribo gun may be the second kind of gun which is often used to spray powder on metal surfaces. The powder is first charged by triboelectric friction and the charged powder particles then go through the grounded substrate. It takes another formulation of powder regarding corona guns.

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