In order to ensure that the powder coating of the workpiece is better, what are the matters that need to be paid attention to when the powder spraying equipment is used for external processing? Let’s take a brief look.
　When using powder spraying equipment, avoid re-contamination of the object to be sprayed by the environment and man-made during the preparation, transportation, and transmission of the construction. Clean construction equipment and clean up the working environment regularly and appropriately. At the same time, it is also necessary to pay attention to the problem of some oil spots that need to be added to overcome and solve.
The construction personnel may also find that the hardness of the coating film surface is insufficient in the hardness test. This may be caused by insufficient hardening ratio, insufficient baking time and insufficient baking temperature. The insufficient hardness of the formulated resin itself may be due to the inconsistent hardening ratio. The baking time and temperature meet the operating conditions.
　If you find that silver particles are visible on the surface of the coated object when using powder spraying equipment, it may be because the spray is too dry, making the silver powder easy to stand. At the same time, improper formulation of the coating itself or wrong dissolution requires review of the formulation of the coating itself, whether the silver powder is completely immersed, and whether the selection of the dust-proof agent is appropriate.
