Abstract

The invention discloses an electrostatic coating intermittent paint supply system and method for high conductive water-based paint. The electrostatic coating intermittent paint supply system includes: a color changing valve group, which is used to provide paint for the electrostatic coating intermittent paint supply system , color change and provide cleaning air and solvent; servo cylinder, which includes the cylinder main body and servo motor, the servo motor drives the screw to drive the piston to reciprocate in the servo cylinder, so as to realize the collection and supply of paint; purge valve group, its Including the first oil inlet valve, the first oil return valve, the second cleaning solvent valve and the second cleaning air valve; the purge isolation module is used to purge and empty the electrostatic isolation tube after the servo cylinder is filled with paint . The present invention adopts the isolation mode of servo oil tank paint supply and paint pipe purge type to carry out high-voltage electrostatic isolation, thereby solving the problem of electrostatic isolation of water-based paint and the problem of waste of oil and gas, and can use the atomizer while retaining the original atomizer Relatively low cost to achieve the coating of water-based paint.

Description

technical field

[0001] The present invention relates to an intermittent paint supply system and method for electrostatic painting suitable for highly conductive water-based paints. Background technique

[0002] Water-based coatings are coatings with water as the dispersion medium. Compared with solvent-based coatings, water-based coatings have many advantages. Water-based coatings can greatly reduce the pollution to the atmosphere, have wide adaptability to the environment, and greatly enhance the ability to prevent fire and explosion. Moreover, the water-based paint does not produce toxic volatiles, thus improving the working environment. Therefore, the water-based paint has the advantages of green, safe, and easy to use.

[0003] However, due to the high conductivity of water-based paints, serious high-voltage attenuation will occur when painting with an electrostatic bell commonly used in solvent-based paints. Due to the leakage of high-voltage static electricity through ...
