Provide the best powder coating system solution
The 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…
DetailsFirst, the voltage The voltage has a great influence on the electrophoretic coating; the higher the voltage, the thicker the electrophoretic paint film, and the spraying ability can be improved for the parts that are difficult to spray, and the construction time is shortened. However, if the voltage is too high, the surface of the…
DetailsChina is already the world’s first paint producer, but compared with the western developed countries, China still has a long way to go from the paint power. At present, China’s coatings industry needs to develop from a large coating country to a strong paint country, which is based on the price, value and quality of…
DetailsThe coating line is a popular product in the assembly line market. The seven components of the coating line mainly include: pre-treatment equipment, dusting system, painting equipment, oven, heat source system, electronic control system, suspension conveyor chain. Wait. It is suitable for painting and plastic spraying on the surface of workpieces. It is mainly used…
DetailsThe coating quality requirements of different commodities are different. What are the customers’ requests for the quality and appearance of the coating for the automatic spraying equipment? The following is an introduction to the main degree of appearance of different grades or areas of regular sprayed products for reference only. 1. Adhesion requirements In the…
