Anti corrosion anti rust high gloss of electrostatic spraying

Anti corrosion anti rust high gloss of electrostatic spraying

As usual powder electrostatic spraying, the number arrangement of spray gun are determined according to the width linear speed of coil, which has the characteristics of anti-corrosion, anti rust high gloss. If the normal gas heating method is used, the linear speed of coil can only reach L520 M / min. if the linear speed is increased, the powder coating will be taken away when the substrate moves at a high speed, the deposition efficiency is only 40% - 50%; moreover, the spray gun is densely arranged, the film thickness of electrostatic coating film is easy to control. Also easy to appear other film defects, such as pitting, orange peel so on. People focus on the radiation curing instead of gas heating curing.

Powder cloud technology

As we all know, the faster the wire speed of the substrate, the more air will move with it. Compared with the "point source" produced by the electrostatic spray gun, MSC's "line source" can produce a powder source 1000 times stronger than that of the electrostatic spray gun, which makes it possible for the powder to penetrate the airflow layer generated by the coil at high linear speed.

The powder cloud can cover four areas: two in the forward direction two in the opposite direction. The outstanding advantage of this technology is that the density charge of the powder cloud are evenly distributed by electric brush in the electrostatic generation area, the thickness of the coating can be controlled by the particle size of the powder the linear velocity of the substrate.
