What's Powder Coating Equipment?

This is a type of coating equipment that assists in applying powder. Powder coating equipment doesn't involve solvents in its processes. The coating is carried out electrostatically and it is then passed under heat, allowing the powder circulate and form a "skin". It could be a thermoset polymer or even a thermoplastic. Generally, it is utilized to give you a hard finish which is harder compared to the conventional point which was formerly used. The primary intent behind by using this devices are for coating metals, including bicycle parts, household appliances, aluminium profiles 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 In comparison with Traditional Liquid Coating 
- It is usually Recycled, Facilitating 100% Reusability In the Substance 
- Produces More secure Waste As compared with Traditional Usage of Liquid 
- Lesser Operating Cost Than Liquid Lines

Technique of Powder Coating

The Powder Coating Equipment work in following basic processes:

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

Processes And Equipment Of Part Preparation

Before the powder coating process eliminating lubrication grease, metal oxides, mud, oil etc are very important. There are various chemical and also mechanical types of removing these substances through the metal surface. The process is dependent upon the performance dependence on the finished product. In spray application process, chemical pre-treatments involve the use of chromates and phosphates. Phosphating and chromating in the substrate occur in multiple stage. Bonding in the powder to the metal involves cleaning in the pre-treatment process. Sand Blasting is an another method of preparing the counter prior to coating. It really is used to provide finishing, etching, surface texturing and preparation and degreasing for products created from wood, glass, or plastic. Different powder coating applications can require various ways of preparation like abrasive blasting before coating. The net consumer market typically offers media blasting services as well as their coating services at additional costs.

Commonly electrostatic gun or corona gun is utilized for using the powder coating to metal objects. Here, lets discuss the working of electrostatic gun. Negative electric charge is imparted to the powder. The negatively charged powder might be sprayed for the grounded object by mechanical or compressed air spraying equipment. Then it is accelerated towards the workpiece with the powerful electrostatic charge. The thing might be heated, and also the powder melts in a uniform film, which is then cooled produce a hard coating. To attain more uniform finish preheating might help but problems can even be created as runs caused by excess powder.

Tribo gun could be the second kind 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 follow the grounded substrate. It requires some other formulation of powder regarding corona guns.

Fluidized bed method may also be used for Powder coating. In the beginning the substrate is heated and then it's dipped into aerated powder-filled bed. Later the powder sticks and melts for the hot object. Most dishwasher racks are coated using this way of [http://people.tribe.net/2fafc668-a1dc-48d6-af83-40022fdafed0/blog/f3631bc0-e2a8-4032-9c98-2caea5617d84 powder coating supplies].
