Explanation of precautions during the spraying process of crack powder coating

Surface decoration technology is a very important means of exterior decoration for many products. Steel wood door plastic powder, crack powder coating, etc. are common decorative powders. Today, the plastic powder manufacturer mainly introduced to us the precautions during the spraying process of crack powder coating.
① In the process of powder coating spraying, the coating thickness is uniform and suitable, and too thick will cause the crack boundary to be blurred; If it is too thin, it is prone to problems such as exposed bottom and shrinkage holes;
② Suggest spraying in order from high to low. Spray the secondary surface first, then the main surface, preferably in one go. Some blind spots require partial repainting, which will cause the original cracks to disappear;
③ To achieve the best spraying effect, before construction, the material should be sieved through a slightly larger screen, and various process parameters such as powder air pressure, atomization air pressure, nozzle to workpiece distance, and spray gun removal speed should be adjusted to achieve the best effect.
④ The cracked powder coating is not resistant to wiping and is prone to color fading.
It is precisely because of the continuous advancement of modern decorative material production technology that we can see so many exquisite surface decoration works today. Decoration is a job that requires both technical skills and artistic integration. With good decoration techniques, one also needs to have a certain level of artistic creativity, coupled with high-quality decorative materials, in order to create exquisite decorations.
