How To Start A Powder Coating ?
Powder coating is applied to large industrial enterprises and small household jobs. With powder coating is a durable coating for internal surfaces of pipelines and other systems prone to destructive external influences. At the same time, powder coating – the easiest and cheapest way to change the color of motor drives. How does one technology combines the ease of production, quality and Availability? For the first time powder coating appeared about half a century ago, but today it is applied universally and almost completely replaced the liquid coating materials. The reason for such wide distribution is simple: Powder coating has no equal in terms of efficiency, quality, and even on environmental indicators. Of course, to perform the work required and the expertise and special equipment, but it all pays off well received result.
How is powder coating? It all begins with the preparation of the surface. It must be thoroughly cleaned, sanded and degreased. For example, in the case of powder coating automotive drive pre-treatment is carried out by sandblasting machine. The surface is cleaned of old paint and from other contaminants. Frequently used formulations with surfactants that allow you to degrease.
Of pre-training product is directed into the chamber of powder coating. Here is needed nebulizer – a special device that allows you to put powder on the surface with a stream of compressed air. He By the way, and electrifies the ink particles, thereby improving their grip. However, such coverage remains extremely fragile, so the product must be sent to the furnace to consolidate the polymerization paint. Curing oven can be operated in different temperature ranges – everything depends on the characteristics of materials. At this stage, powder coating spray application layer must melt to a liquid state and then freeze solid coating. Often used special thermosetting paint, which not only melt but also come in a special chemical reaction that increases the strength of the layer.
