| 摘要 |
The invention relates to a method for powder-coating a substrate (5), especially temperature-sensitive substrates such as wood, wood-fibre materials, plastic materials, rubber, woven fabric, paper or cardboard. According to said method a heat-sensitive powder is deposited as a base coat (6) on the uncoated surface of the substrate (5). The powder is then either heated continuously to cross-linking temperature by means of infrared radiation having at least fractions in the near and/or short-wave infrared range, and hardened; alternatively, the powder is continuously heated to gelling temperature, cross-linking is completed in a subsequent step and the powder is then hardened. To generate the infrared radiation the invention provides for the use of halogen lamps (7) in combination with a reflector (8) for reflecting the radiation emitted in the direction of the substrate. The halogen lamps (7) are operated in such a way that a maximum radiation flux density of the emitted radiation is in the near infrared region.
