Fluidized bed which is composed by a porous separator and the container, a porous separator vessel into upper and lower portions. Their work is this: the container section below the bulkhead pass into the air, compressed air through a porous separator so that the role of the air flow above the powder were not suspended up and roll in the upper spray container processing factory, showing "boiling "state. Preheated workpiece through the "boiling" powder coated area achieve results. Preheating temperature of the workpiece can be slightly higher than the melting temperature of the powder. Fourth, the construction primer coat: 1. Good scraping putty spray processing appliance manufacturers, polished smooth, you can spray the primer. 2. The paint bucket syrup, stir, add hardener in proportion, the curing agent is added, stir, curing 30 minutes. 3. According to the amount with paint, how much with how much, with a good paint should be used within 8 hours. 4. With special diluent to adjust the viscosity of the construction of approximately Tu -4 # {cup, 17-22 seconds} for air spray. 5. Recommend spraying two, in the interval of 24 hours, after the second track completely dry {ambient temperature above 15 ℃, 24 小时 household appliances spraying processing factories, according to the construction needs of irons spray processing factory, with putty defects, sanded smooth , then spray the second tract primer. 6. Requirements coating film is smooth, no sagging.
