First of all, pretreatment is an indispensable step. The pretreatment of industrial aluminum profile is mainly to generate a layer of chemical conversion film on its surface. The first step of pretreatment is to remove oil, to ensure that there is no residual oil stains and impurities on the surface of the industrial aluminum profile, and to ensure the clean surface of the industrial aluminum profile. Then after the oil is removed with water quickly rinse again, then you can carry out the chemical conversion process, using the idea of anodic oxidation to get a layer of chemical conversion film on the surface of the industrial aluminum profile.
Then continue to wash, and then use the drying equipment to dry. In this way, the industrial aluminum profile is basically equipped with the conditions of electrostatic spraying. Of course, before spraying, we should also prepare the tools and equipment used, especially the fixture, which is specially used to fix the industrial aluminum profile. It needs to ensure that it has enough bearing capacity and will not break in the process.
If there is a special shape of the industrial aluminum profile, it is also necessary to maintain some inclination when the fixture is fixed, so that the powder can be more evenly coated on the surface of the industrial aluminum profile. Make sure you have enough powder before you start spraying. For deep grooves, use a little more powder.
