Fourth, the construction primer coat: 1. Good scraping putty, 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, more than after the second track completely dry {ambient temperature 15 ℃, 24 hours, depending on the construction needs Teflon spray processing, defects with putty, sanding smooth paint spray processing, and then The second tract spray primer. 6. Requirements coating film is smooth, no sagging. Work electrostatic spray gun or spray pan, spray cups, spray paint particles then negative part processing factories, the workpiece then positive and grounded at high voltage power supply voltage is applied, the gun (or spray pan, spray cup) of the ends to form an electrostatic field between the workpiece. Paint particles are subjected to an electric field strength of the electrostatic field voltage and the charge amount is proportional to paint particles sprayed processing, and is inversely proportional to the distance between the gun and the workpiece, when the voltage is high enough, the vicinity of the lance end forming an air ionization region, intense ionized air and heat, so that sharp edges or lance end around the needle electrode is formed of a dark red halo, can be easily seen in the dark, then a strong air corona discharge.
