Provide the best powder coating system solution
Time spent in the oven is determined by the coating suppliers, who specify the required time at a given temperature to thoroughly cure the coated product. However, line speed, product window size, hanging spacing and product weight/conveyor weight must be defined prior to designing a cure oven. Line Speed.Assume a production rate of 600 parts…
DetailsTips on how to choose the system that best suites your coating needs. One of the most common questions asked of those in the powder coating industry is whether to use a manual batch-type system or an automated line. The answer isn’t always easy: Batch systems and automated lines use different approaches to powder coating,…
DetailsPowder coating refers to a new type of solvent-free 100% solid powder coating. It is solvent-free, non-polluting, recyclable, environmentally friendly, saves energy and resources, reduces labor intensity and has high mechanical strength of the coating film. Classification Powder coating is a completely different form from the general coating, it exists in the state of microfine…
DetailsThe production of powder coating booth is a key process in the production of spraying, and the key to the surface quality of the sprayed workpiece lies in the control of the process parameters. The amount of powder and atomized air are the two key technical indicators. Before the formal spraying of powder, you can…
DetailsThe lower the dielectric constant of powder, the easier it is to charge the particles, but the easier it is to lose the charge, which is reflected in the powder adsorption force on the workpiece, and the powder will fall off when it is slightly vibrated. For electrostatic spraying powder coating, should be as high…
DetailsThe significant difference between powder coatings and solvent-based coatings is the different dispersion media. In solvent-based coatings, organic solvents are used as the dispersion medium; in powder coatings, purified compressed air is used as the dispersion medium. Powder coatings are dispersed when sprayed, and the granularity of the coating cannot be adjusted. Therefore, the fineness…
Details1.high-voltage electrostatic generator must be grounded wire. High-voltage electrostatic generator ground wire is the basic safety operation, electrostatic spray gun ground wire is also taken from the high-voltage electrostatic generator, so it should be confirmed that the ground is actually grounded. 2. the object to be coated to maintain a grounded state. The painted…
DetailsThe basic of the powder coating oven design is to find out the necessary heat. Need to calculate the heating up time (from the start of the switch to the time to reach the temple temperature) sweep heat, the necessary heat per hour during production operation, according to the calculation results to decide the capacity…
DetailsIn simple terms, the role played by metal degreasing is to remove the dirt accumulated on the metal surface during previous operations and to prepare it for subsequent operations. Cleaning metals involves not only the selection of the type of degreasing agent, but also the appropriate degreasing process and process equipment that must be used…
DetailsThe fineness of electrostatic powder particles: The significant difference between powder coatings and solvent-based coatings is that the dispersion medium is different. In solvent-based coatings, the use of organic solvents as a dispersion medium; and in powder coatings, the use of purified compressed air as a dispersion medium. Powder coatings are dispersed during spraying and…
DetailsIn 1962, the French Sames Company successfully researched powder electrostatic spraying equipment, which laid the foundation for the rapid development of powder coating technology. Powder electrostatic spraying method is the most widely used process in electrostatic coating construction. The electrostatic spray gun adsorbs the powder on the surface of the object to be coated by…
DetailsIn the use of electrostatic spraying equipment often happens some big or small accidents, how to avoid this aspect of the accident? First, most of them are caused by the failure of grounding and forming an insulated state. The conductive objects in the coating room must be clearly distinguished from high voltage potential or grounding…
