1. Ordinary coating process
Generally speaking,pretreatment is needed before spraying, which is concluding remove oil,remove rust, phosphating.All of this make up the automatic coating machine .Besides,the powder coating machine price is reasonable.
2. Basic principle of electrostatic spraying
According to the electrophoretic physical phenomenon,the spraying parts as the anode,and the powder coating gun as the cathode,then connecting the power supply and form the high voltage electrostatic field.Polyester powder coating is safe. And you can rest assure the powder coating machine cost,that will make you have a pretty competitive price among powder coating machine manufactures.
3. Electrostatic spraying and sprinkler classification
According to the spraying method,electrostatic can be divided into 3 types,including Air atomization electrostatic spraying,hydraulic atomization electrostatic spraying,centrifugal electrostatic spraying.The sprinkler of the professional powder coating gun can be different accoding to the characteristic, properties of powder,etc.To be honest,powder coating gun china often have powder coating gun best price.
