Abstract
In line with the energy transition, it is desirable to replace fossil fuels in the curing process of industrial powder coatings. Infrared heating is the considered method here. Near Infra Red-emitter arrangement in the reflective heating chamber, their geometry and the dwell time of the components are crucial for a successful and efficient process. Process optimization has to consider the optical parameter variation of the powder coating during the procedure. Measurements in the NAPUBEST (“Nachhaltige Pulverbeschichtungs-Technologie”: sustainable powder coating technology) prototype are compared with optical simulations of the setup to get the simulation parameters in agreement with reality and to provide a foundation for the layout of industrial processes.
Key words: IR-curing / Optical simulation / Powder coating / Sustainable energy transition / Infrared heating
