What exactly is Powder Coating Equipment?

It is a sort of coating equipment that helps in applying powder. Powder coating equipment does not involve solvents in the processes. The coating is completed electrostatically and it is then passed under heat, allowing the powder circulate and form a "skin". It might be a thermoset polymer or even a thermoplastic. Generally, it is accustomed to offer a hard finish that's harder compared to the conventional point that was formerly used. The primary function of applying this products are for coating metals, for example bicycle parts, household appliances, pool enclosures and others.

Advantages

Few benefits of powder coating are mentioned below:

- Emission Of Volatile Organic Compounds Are Reduced By Coating The Metals 
- It generates Much Thicker Coating As Compared To Traditional Liquid Coating 
- It may be Recycled, Facilitating 100% Reusability In the Substance 
- Produces More secure Waste In comparison with Traditional Use Of Liquid 
- Lesser Operating Cost Than Liquid Lines

Process Of Powder Coating

The Powder Coating Equipment operate in following basic processes:

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

Processes And Equipment Of Part Preparation

Prior to powder coating process elimination of lubrication grease, metal oxides, mud, oil etc are very important. There are several chemical along with mechanical types of removing these substances through the metal surface. The method depends upon the performance feature the finished product. In spray application process, chemical pre-treatments involve the use of chromates and phosphates. Phosphating and chromating with the substrate happen in multiple stage. Bonding with the powder on the metal involves cleaning inside the pre-treatment process. Sand Blasting is definitely an permanently of preparing the surface before 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 alternative methods of preparation such as 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 can be used for applying the powder coating to metal objects. Here, lets discuss the working of electrostatic gun. Negative electric charge is imparted towards the powder. The negatively charged powder will be sprayed for the grounded object by mechanical or compressed air spraying equipment. It's then accelerated towards the workpiece with the powerful electrostatic charge. The article might be heated, as well as the powder melts in to a uniform film, which is then cooled to create a hard coating. To attain more uniform finish preheating may help but problems can be created as runs due to excess powder.

Tribo gun could be the second form of gun that is utilized to spray powder on metal surfaces. The powder is first charged by triboelectric friction which charged powder particles then adhere to the grounded substrate. It requires another formulation of powder regarding corona guns.

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