Electrostatic sprayer

First, the working principle of the powder coating upon electrostatic powder spray gun, while the dispersion of the powder particles with a negative charge, the particles by electrostatic attraction and the role of airflow, painted on the ground, with a positive charge to be coated , heating and melting cured film. Equipment composition electrostatic powder coating equipment from the spray booth, ventilation systems, powder recovery, sifter, feeders and other components. Powder room with a solvent-based paint spray booth is similar to, but different bottom shape of the bottom should be designed so as not to stack or partial stack less shape of the powder. To prevent the powder flying from the entrance to the inner chamber body shop, set up outside the room outside the powder room, paint handling and easy cleaning. Powder room exhaust ventilation and wind speed and operating environment, the LEL of dust and transfer efficiency and so on, need to be considered. Air vents located beneath the powder room, funnel-shaped, through the suction tube from the suction side of the recovery unit. Such a device is relatively simple, only for small batch production. In the case of mass production, in the powder room should be set below the vibration, automatic cutting boards, which can automatically and evenly into the flour recovery.
