The core part of the static spraying machine is made of most updated nano material. It is small in size and high in efficiency. The controlling circuit has the distance-current-voltage automatic adjustment function that may set up the largest discharge current of the spraying gun to guarantee the best electric charge of the powders. It is easy to pass Faraday shielding cage, eliminate the phenomena of anti-ionization, solve completely the phenomena of strike-fire, reduce greatly the generation of orange peel of the coating and guarantee the quality of the coating. 1. High-voltage static spraying gun (Built-in high-voltage generator. Input 5-12V. Frequency 18KHz. Output 40-70kV. Negative polarity). 2. Controller (Static high-voltage controlling circuit: Output voltage 5-10V. Frequency 18KHz. Distance-voltage-current automatic tracing and adjusting circuit, set up the maximum discharge current of the spraying gun, guarantee the best electric charge of the powders. Pneumatic control: Control the opening and the closing of electromagnetism valves. Adjust the volume of the air and control the volume and the flow of the powders to make sprayed powders in continuous fog and guarantee the quality the coating.) 3. Spraying gun control unit ESGC spraying gun control unit supplies all powder-supply and air-supply function for manual or automatic spraying guns. This system uses the most advanced intelligent total energy static powder spraying technology (patent technology) in the world. This system accords with the most updated European and American safety standards and use the moat updated LCD text input parameters, display the air pressure, current and current value.
