ELECTROSTATIC SPRAY PAINT GUN 

Electrostatic gun is the basic product of industrial spraying equipment. In the coating process line, the electrostatic spray gun is the main body of the surface treatment of the core equipment, it is through the use of low-pressure high atomisation device and through the electrostatic generator to produce electrostatic field force efficient and fast coating of the coating to the surface , So that the coating to achieve the perfect surface treatment, so the electrostatic spray gun is grounded as a positive electrode, paint atomization device for the negative electrode, and the coating atomization device with high negative voltage, made between the two The electrostatic field allows the atomized coating particles to be negatively charged, so that the coating is effectively adsorbed on the opposite electrode by the method of the surface of the electrostatic coating.    

So why is it going to be painted as a positive electrode and the paint atomizer is made of negative? It is, on the other hand, its transfer to spark discharge is more unsafe. In order to carry out electrostatic coating, the coating of the ground is an important must be conditions, that coating must be a good conductor of electrical. Wood is usually considered a bad conductor, but its moisture content of 8% or more, you can practice electrostatic coating, and experience has also been confirmed.    

This is the usual electrostatic coating, the current between the positive and negative dip current is 20 ~ 50 microamps (MICRO-AMPERE), very small, so although it is like wood, the larger resistance of the object can also be implemented Electrostatic coating.
