What are different types of powder?
different types of coating powder powder can be divided into two main categories: thermoplastic and thermoset. Thermoplastic powders are applied to the work surface and heated or cured, during which the process melts and flows into a smooth leaf that hardens after cooling. Thermoset powders operate in almost the same way, except that the cure process changes their chemical structure. Both types are used as an alternative to apply wet color, especially in objects such as households, cars and motorcycles, and both provide a durable and attractive surface. In addition, both types of powder coating powder are used as covers for metal objects that are not visible but need protection against corrosion and oxidation.
Thermoplastic powder The coating contains substances such as nylon, poly-vinyl chloride (PVC), polyolefin and polyester. Each of them melts at different temperatures and melts again after this temperature. This makes it easier to recyIt limits the use of thermoplastic powders to an environment where the temperature is unlikely to reach its melting point. These coatings are usually used in indoor and outdoor applications such as appliances, car surfaces and furniture on the terrace. In addition, most of these substances have special features that make them particularly suitable for certain applications. For example, nylon is often used as a coating for gears and conveyor components due to its low friction coefficient. Polyester, on the other hand, is abrasion resistant, has a pleasant look and weather, so it is ideal for outdoor furniture and exposed car parts.
Thermoset powder powder, as soon as it melts into a smooth workpiece coating, after re -omitting the original melting temperature, because the chemical change is called, it is called stretching, C, C, CHRMO combines separate components togetherCreates new compounds. In addition to greater heat resistance than thermoplastic powders, they are also generally heavier. Some of the different thermoset materials are epoxy, acrylic, epoxy-polyester hybrids and silicon-based powders. Their heat resistance is ideal for higher temperature environments, such as automobile components of exhaust systems, inner furnace walls and furnace stands and grilling. Some, such as epoxy, respond poorly to ultraviolet (UV) rays found in the sun, limit their usefulness to an environment where they will not be exposed to the sun, such as underground service pipes.
The coating powder is created by one basic process: the granules are mixed together with the toughs and pigments, heated and pushed into a sheet, which is then divided into chips, which are then milling into fine powder. Unlike wet color, which requires a solvent in which the color is to hang the powder coating powder is dry when applying. AnyThe powders are sprayed on the surfaces to be painted, while others are set in the tub in which the workpiece is submerged. The powder itself has no adherence properties, which requires that the workpiece be either prepared or electrostatically charged to adhere to the surface before heating or a curing process.
powder coating is often used as an acceptable alternative to metal metal. Interestingly, while metal plating stores an extremely thin layer of metal on a working piece, sometimes only a thousandths of a thick thumb, the powder coating of the building leads to a clear, hard, durable surface, sometimes up to a quarter inches to a half inches (0.635 cm-1,27 cm). In fact, the stronger the powder of the coating, the more smoother it will be on the coated object; Very thin coatings tend to be closer in the texture than smooth. Electropled coatings, on the other hand, will be very smooth, regardless of how they are applied if the part has been polished smooth.
