What are the biggest challenges when applying powder coating to steel structures?

The advantages of powder coating, due to which it owes its popularity, are, first of all, the durability of paint coatings and their high aesthetics. The surface after powder coating is perfectly uniform and even, as well as resistant to ultraviolet radiation. Another advantage of this technique is its environmental friendliness. Therefore, it is not surprising that it is widely used, including for industrial applications. Read what is important when painting steel structures and what problems are associated with it.Powder coating-step by step
The powder coating process is multi-stage. The first step, and this is very important, is proper cleaning and preparation of the surface for varnishing. Rust and all other contaminants must be removed from it and degreased. Good results are achieved by sandblasting or shot blasting. Thorough cleaning and degreasing of the surface from dirt improves the adhesion of the paint.Varnishing is carried out with special units that allow powder coating to be applied by electrostatic or electrokinetic spraying. As a result of these phenomena, the powder is effectively attached to the varnished surface. The next step is the drying and curing of the paintwork.The exposed element is dried using special dryers that heat the surface to a temperature of 150 degrees, and cured in furnaces at a temperature of 220 degrees. In these furnaces, the powder coating dissolves and cures and acquires its operational properties."The most important process during powder coating is the polymerization of the lacquer powder in special tunnel furnaces. It takes place in 4 zones, the parameters of which correspond to the type of applied products and the manufacturer's recommendations. This is usually done at a temperature of 180-200 ° C and lasts, as a rule, from 10 to 20 minutes. The size of the painting chamber and tunnel furnace may be a limitation when completing orders. In our company, we allow component paint machines with a maximum size of 1,000mm x 1,100 mm x 2,500 mm. We provide a powder coating speed of 4 meters per minute using 28 guns mounted on four manipulators that operate simultaneously on two axes.”
Powder-coated steel structures
The powder coating provides effective protection against corrosion. The quality of the paintwork after the polymerization process is characterized not only by high aesthetics, but, above all, by exceptional durability and resistance to ultraviolet radiation. This ensures that the varnish does not decompose and does not change color for many years. Therefore, powder coating is usually used to protect steel structures. It can be used without restrictions for all metal elements of fences, stairs, railings, machine and vehicle parts, and all other steel and aluminum structures.One limitation is the need to dismantle the elements, which must be thoroughly cleaned and placed in the paint chamber. Another major performance problem is the size of the cabin and tunnel furnace, which limit the technological capabilities of powder coating large elements of steel structures. 1xBet Sports & Casino Bonus.
