Definitions

  • the invention relates to a method with the features of introductory part of claim 1.
  • EP-A-0 348 882 discloses a device for drying water-soluble Varnishes for the production of test pieces for the Quality inspection described. It is in one with one Infrared heating source chamber introduced air from below and subtracted up. The air flow is therefore in the aligned essentially transverse to the direction of the infrared radiation.
  • the invention has for its object that from GB-A 673 956 known methods so that the drying and / or curing water-dilutable coating systems, especially of paint and base material essentially accelerates and improves without increasing the energy requirement becomes.
  • the invention consists essentially in that the procedural steps of the characterizing part of claim 1.
  • the air flow (or air flows) is approximately aligned perpendicular to the direction of the infrared rays the removal of water vapor molecules is improved. This advantage also occurs when neither the subject still the infrared radiator and the blowing nozzles are moved what makes the invention also suitable for refinishing.
  • the intensity of the air flow and the intensity of the heat input via the infrared heater (s) during drying and / or curing is changed independently of one another.
  • the procedure is, for example, that after application a first layer of high performance coating (e.g. the highest performance) of the fan and reduced Power of the infrared radiator is worked. After one others, e.g. the second layer of the coating to be produced was applied, the performance of the fan can be reduced to one higher, e.g. increased to its greatest performance and performance of the infrared radiator to a fraction of its maximum possible performance can be reduced.
  • the invention provides a device with which the process of invention is advantageously carried out can be.
  • the fans or blowers are arranged so that they one Generate airflow that is substantially perpendicular to the Direction of the infrared radiation and the for example, about 200 to 300 mm wide space from the Surface of the infrared beam and the object with the to drying and / or curing coating limited is flowed through.
  • the air flow causes evaporated water to be removed during the curing and / or drying process in that Air with high humidity constantly through air with low humidity is replaced, which is essential in comparison to EP-A 203 377 is more effective because the air flow is essentially parallel is aligned to the infrared radiator and the space between strikethrough the object and the infrared emitter.
  • the coating to be dried heat by infrared radiation fed and at the same time with the air flow at the Evaporating water molecules surface of the coating effective derived.
  • the invention works in such a way that the Airflow in the space between the infrared heater and the Object on which to dry and / or harden Coating is applied from top to bottom or horizontally aligns.
  • FIG. 1 shows the example of a two-layer Orders of filler material with a total thickness of 120 ⁇ the process flow during drying and curing after method according to the invention. That is on the vertical axis Time in minutes and on the horizontal axis of the chart the power output is plotted in% of the maximum power (100%).
  • the solid line shows the power output of the infrared radiator and the dashed line the course the output power of the blower (fan), which is an embodiment may have according to one of FIGS. 2 to 6 again.
  • the infrared radiator 1 the contour of the object on which a coating (e.g. filler or paint) to dry on an aqueous basis and / or is to be hardened, aligned or set up appropriately will.
  • a coating e.g. filler or paint
  • Infrared heater 1 is a fan in the manner of a tangential fan 5 is provided, which is housed in a housing 6.
  • a grid 7th covered air intake opening provided at the rear of the housing 6 .
  • the exit opening 8 of the housing 6 is directed downwards and preferably with a filter.
  • Fig. 7 shows a diagram with the process flow for the Drying and curing a topcoat in two layers is applied.
  • Fig. 9 shows the process flow during drying and Curing filler compound according to the invention Method.
  • the devices according to the invention are a controller can own in which the most favorable process flow for various coating systems and types of coating (especially the thickness of the coating) is, so that the required or desired process flow for example by pressing a corresponding key or Enter an appropriate code or password can be accessed. This also ensures that the drying and curing each optimally the regulations adapted by the manufacturer of the coating system becomes.
