1) The heat exchange furnace should control the air flow rate inside the furnace not to be too strong to avoid blowing off the powder adsorbed on the workpiece. Only in this way can the workpiece be placed tighter on the lifting tool. Usually, the air flow rate should be maintained within the range of 1-2m/s.
2) Time and temperature are key factors in curing powder uncoated coatings. At lower curing temperatures, longer and shorter curing times are usually considered equivalent.
3) If the adhesion of the coating should increase, generally in addition to surface treatment, such as baking, sandblasting, etc., this surface treatment has a time limit and must be painted within a certain period of time.
However, although some powders such as polyester powder cannot achieve complete curing by reducing the curing temperature and increasing the curing time, the aging and corrosion resistance of the coating will still be affected. Therefore, when painting this type of powder, especially when using super weather resistant powder, it is necessary to ensure that the furnace temperature meets the furnace temperature requirements of the powder supplier.
