What are powder coatings?
powder furnaces are devices used in the dry cover process. After the item is covered, it is placed in one of these furnaces where the coating cures. This causes a chemical reaction that causes the coating bond with the surface of the work. After the coating is completely cured, it is almost part of the original item. There are two main types of furnaces with powder coating, convection furnaces and infrared furnaces.
Convective furnaces work similarly to a common home furnace. Heating elements or thermal openings create zones of intense heat. This heat warms the air and creates the movement of air. When the air moves, it cycles around the oven and finally warms the entire inner area. The most important difference is the focus on infrared oven. The elements used in these systems have a more focused heat directing method. Results to the fact that more heat goes to Object and less lost in the air. Some types of powder coating will work on non -metallic materials, but it is a small fraction of the powder coating industry. OThe tank has any pressing material or Bursa removed to be as close as possible to the completed quality. It is then cleaned with industrial solvents or sand.
The next step in the process of coating the powder is to apply the real powder. There are a number of different ways to achieve this, but most forms include generating positive or negative cartridges in a workshop or powder. One of the more common methods is called an electrostatic coating. In this process, the working part is grounded and the powder is negative. The powder is naturally attracted to the workshop as a result of the polarity difference.
After the material is covered with powder, it enters the furnace for powder coatings. During this part of the process, the working piece is heated to a sufficiently hot temperature to melt the powder but cool enough to prevent damage to the object. When the powder melts, it is evenly coated with workpiece and changes mechanically and chemically. OftenThe working piece will be in the oven for less than 20 minutes.
In most cases, the powder is made of a human -created material such as polyester or epoxy. When this material melts, it flows into small corners and skulls. This mechanical change creates a barrier to the environment. In addition to mechanical protection, the molten material forms the shape of the molecular grid. This grille is extremely resistant to damage and wear.
