In the process of powder spraying, we need to pay attention to the electrical conductivity of the spadder, and the creep layer on the spadder should not be too thick, and the specific coating on the appliance can be removed by centralized burning when it is too thick, because the workpiece is relatively heavy, it must be designed to be a hanger, and it must be stable and reliable. The iron staircase takes the pre-drying goal, one is to better remove the remaining moisture on the workpiece, the second is to fully ensure that the powder coating of certain thickness is better attached to the surface of the workpiece, and the third is to ensure that the workpiece is heated as soon as possible and evenly to speed up the curing process.

For iron staircase products must be based on the characteristics, the actual use is the combination of automatic spray gun plus manual spray gun, real-time monitoring of the quality of the target powder, to better ensure that product quality is stable enough. Under normal circumstances, the curing conditions of pure polyphenol powder coatings are standard, and the curing temperature and use time are guaranteed by adjusting the temperature and chain speed of the heating furnace. Iron staircase is taken cold air drying, in the overall process of drying, the workpiece is actually inspected, and for the permit shortcomings, such as flow hanging, dew bottom and hole can be diluted powder such as acetone coating, while the workpiece is not dry coating or spray on the surface of the shortcomings with waste heat curing for major shortcomings need to be repaired, according to the thickness of the film to choose different treatment methods, Under normal circumstances, there are more direct methods of re-dusting, mechanical grinding and treatment with defilm agent. Wrought iron stairs are coated with polyester colored powder to form a permanent coating that will not rust, no matter what the environmental conditions.
