Definitions

  • the invention relates to a method for energy saving Drying of paints on metallic or non-metallic Individual parts or assembled assemblies of any structure and with complicated geometry in a continuous process or in stationary operation in a heated drying room, especially of paints on aluminum components or on components made of fiber composite materials for aircraft, wherein preferably water-dilutable as well as solvent-based varnishes
  • One or two component paints on epoxy or Polyurethane base are used, being the heat source in the Drying room at least one microwave module for generation of by means of waveguides with defined outlet openings used microwaves introduced into the drying room and where air to flow around the individual parts or Assemblies are introduced into the drying room.
  • Drying on metallic components or components lacquers applied from fiber composite materials, in particular of two-component paints, in convection ovens by means of warm air within a temperature range of e.g. B. 40 to 90 ° C is generally known.
  • The is also known Drying of such varnishes with the help of infrared radiation. Disadvantages of these drying processes are proportionate high energy consumption and in long drying times to see. Can also disadvantageously by means of infrared radiation due to the formation of shadows Components of simple geometric shape are dried.
  • FR 24 58 323 describes a method for coating a Described substrate with which a thin on the substrate Layer of a coating is applied.
  • the substrate can consist in particular of glass or an analog material.
  • the coating is made by applying microwave energy treated warm, the special feature of which is that this energy in a selected frequency range lies, which is suitable for certain components of the Selectively stimulate coating.
  • the regulation of the microwave is designed in such a way that the microwave radiation fed into the drying room so far changed in frequency is that the temperature of the coating is constant Maintains nominal value. This is done with a commercially available Pyrometer.
  • the microwave directly affects the coating here.
  • Some of the varnishes are specially made for microwave drying modified, e.g. through coal dust. It will uses only non-conductive substrate materials, frequencies higher than 2.45 Ghz are also used.
  • DE 41 21 is the closest prior art 203 A1 a method and an apparatus for drying water-soluble dispersion varnish on paper or cardboard webs known or arcs using microwaves. It will preferably commercially available and approved oscillators used the microwave energy in multiple arrangement couple into waveguide. The webs or arches are dried in a pass, and remains after drying a negligible residual moisture with the most economical Energy.
  • the invention is therefore based on the object of an energy-saving To create drying process with which also a fast drying of components with complicated geometry is ensured.
  • the object is achieved in that the air introduced with an additive with a dipole character is enriched so that the air mixture has a relative Share of additive within a given controllable range from 20% to 90%, and that the proportion of additive in the drying room complied with becomes.
  • the method according to the invention is advantageous fast drying of components of any geometry at relatively low temperatures and at a uniform heating of the paint surfaces achieved what is special for aluminum components used in aircraft construction or components made of fiber composite materials are an advantage is.
  • the method according to the invention advantageously makes itself take advantage of the fact that to run a more effective chemical crosslinking is part of the additive for those surrounding the individual parts or assembled assemblies Air serves as a reaction partner. That from air and one admixed additive produced air mixture flows around the components or assemblies in the drying room, the molecules of the air mixture from the microwaves in Vibrations are set. That way in the air mixture resulting heat energy is on the to be dried Paint surface transfer and favors chemical cross-linking.
  • nine microwave modules with four magnetrons each with a high-frequency power from Z. B. 1.2 KW each can be used. From this results the total output of 43.2 KW, of which about 36 KW can be used.
  • the additive preferably water vapor
  • the object is also achieved in that the coatings with a polarizable dielectric as an additive be enriched and that the additive during the microwave radiation directly to increase the temperature of the Lacquer layer and / or by exiting the lacquer layer in the air surrounding the individual parts or assemblies and thus to increase the temperature of the mixture of air and additive is used.
