Definitions

  • the invention relates to a method for drying paints on metallic or non-metallic parts or assembled assemblies of any structure in a continuous process or in stationary operation in a heated one Drying room, especially puddles on aluminum components or on components made of fiber composite materials for aircraft, preferably as water-borne varnishes as well as solvent-based one- or two-component paints be used on epoxy or polyurethane basis.
  • Drying on metallic components or components pools made of 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 21 203 A1 describes a method and a device for drying water-soluble dispersion varnish Sheets of paper or cardboard or sheets using microwaves known. They are preferably commercially available and approved oscillators used in multiple Coupling the microwave energy into the waveguide. The webs or sheets are dried continuously, and after drying, a negligible residual moisture remains with the most economical use of 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 as Heat source in the drying room at least one microwave module for the generation of by means of waveguides with defined Exit openings in the drying room introduced microwaves that air is used to flow around the individual parts or assemblies introduced into the drying room is that the air introduced with an additive Dipole character is enriched in such a way that the air mixture a relative proportion of additive within a given controllable range from 20% to 90%, and that the proportion of additive in the drying room is observed 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 air mixture produced with mixed additive 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.
  • Embodiments of the method according to the invention are in the Subclaims 2 to 9 described. These configurations consist, for example, that the items on one Conveyor belt - preferably in those located on the conveyor belt Containers - to be transported through the drying room.
  • a chain conveyor can also hang through the drying room transported individual parts or assemblies or also used a batch dryer in stationary operation will.
  • the additive preferably water vapor, to generate the specified moisture content either by in the vicinity of the magnetrons of the microwave modules arranged fine atomizing nozzles or by means of adjustable Air conditioning units are introduced into the drying room. It is also provided according to the invention that as an additive to generate the predetermined moisture content in the Solution arranged near the magnetrons of the microwave modules with known vapor pressure is used by a blower is introduced into the drying room.
  • the object is also achieved in that as a heat source in the drying room at least one microwave module for the generation of by means of waveguides with defined Outlet openings introduced into the drying room Microwaves are used that the varnishes with a polarizable Dielectric can be enriched as an additive, and that the additive during microwave radiation directly to increase the temperature of the paint layer and / or Leaving the paint layer into which the individual parts or Air surrounding assemblies and thus to increase the temperature of the mixture of air and additive is used.
