Brief introduction of spray technology

- Mar 22, 2018 -


Plastic spray is a surface treatment method for spraying plastic powder on parts. 


Spray molding, also known as electrostatic powder spraying, is a common metal surface treatment technology since 1980s. 


Compared with the surface treatment of ordinary spray paint, the technology has the advantages of advanced technology, energy saving and high efficiency, safe and reliable, bright color and so on. 


Therefore, it is often used in the field of light industry and household decoration. 


The working principle is that the plastic powder by high voltage electrostatic charging equipment, under the action of electric field, the coating is sprayed onto the surface of the workpiece, powder can be uniformly adsorbed on the surface of the workpiece, forming a powdery coating; and powder coatings after high temperature baking after leveling curing, plastic particles will melt into the final coating protection effect is different the dense layer firmly attached to the surface of the workpiece;
