Provide the best powder coating system solution
The color difference is simply the difference in color. After the high temperature curing of the workpiece of the electrostatic spray equipment, the color of the surface is different, which is called “color difference”. Under normal circumstances, the problem of paint chromatic aberration in the spraying of electrostatic spray equipment occurs during the commissioning phase:…
DetailsElectrostatic spray is a commonly used spray method. The surface of the workpiece sprayed with electrostatic spray is smooth, the coating is thick, and the defects of particles are not easy to occur. Moreover, the adhesion of the surface coating film is good, and the corrosion resistance and weather resistance are excellent. Electrostatic spray applications…
DetailsThis article was written because of the customer’s question, I found that there are many problems in the past few years, the customer still does not understand, so I decided to write this article to share what I know, I hope to give some help to this industry. First of all, let’s talk about the…
DetailsThe discoloration of the paint mainly refers to the discoloration of the varnish. The varnish was originally a clear, colorless or extremely pale yellow, which turned brown or black after discoloration. The color paint also has a phenomenon of discoloration, which is mainly manifested by the dark color of the color paint. The reasons for…
DetailsThe inside of the automatic spray gun has a pneumatic piston mechanism with a stainless steel needle above the piston and a set of high tension springs behind the piston. When the compressed air stops supplying, the spring pushes the piston and the needle forward. When the needle and the nozzle are closely matched with…
DetailsIn general, our answer is that the main factor affecting the charge and retention of the powder particles is the dielectric constant of the powder. The lower the dielectric constant of the powder, the easier it is to charge the particles, but the easier it is to lose the charge. This is reflected in the…
Details1. In order to ensure the cleanliness of the air supply required for the coating process, the filter bag and filter layer must be properly selected. In the spray booth, the air supply system is generally provided with coarse filtration (initial filtration) and fine filtration, respectively, using primary and intermediate effect filter bags. In the…
DetailsThe spray booth is a non-standard equipment and must be properly selected and carefully designed to achieve the best economic and technical results. The most basic task of the spray booth is to remove the paint mist, paint dust, solvent, etc. from the spraying process. The paint mist is sprayed paint particles, which are still…
DetailsThe coating pretreatment includes three parts of degreasing, descaling and phosphating. Phosphating is the central link. Degreasing and derusting are the preparation steps before phosphating. Therefore, in the practice of producing electrophoretic coating production line, it is necessary to focus on phosphating work and to proceed from the requirements of phosphating quality. Good degreasing and…
DetailsElectrostatic spraying technology uses the electrostatic principle to surface the workpiece, so the entire powder coating process also requires a complete powder coating equipment to implement. Depending on how the powder is sprayed and the recyclability of the powder material itself. The powder coating equipment in the usual sense includes a powder electrostatic spray gun…
