Abstract:
A heating arrangement, comprising a combination of the following features:a) at least one heating element (3) in the form of a flat element with two opposite-lying electric conductors and a coating arranged therebetween comprising a coating material for radiation surfaces to produce electromagnetic waves, composed of binding agent, insulating agent, dispersing agent, water and graphite, characterized in that the coating material has the following composition i) 55 to 65% amount of substance (mole fraction) of a base material comprising: ii) 39 to 49% amount of substance binding agent, 18 to 23% amount of substance insulating agent iii) 18 to 24% amount of substance dispersing agent, 12 to 16% amount of substance distilled water, b. 35 to 45% amount of substance graphite, the composition of the binding agent being: i) 64 to 79% amount of substance distilled water ii) 4 to 6% amount of substance sulfated oil; 0.16 to 0.24% amount of substance phenols or 0.05 to 0.5% amount of substance benzoisothiazolinon; iii) 15 to 19% amount of substance casein; 0.8 to 1.2% amount of substance urea; iv) 2 to 3% amount of substance alkali diluent; v) 2.5 to 3.5% amount of substance caprolactam; and, whereby by means of the coating material from the insulating agent the graphite and the binding agent electromagnetic waves can be emitted, c) at least one controller/regulator (7) with a harmonic generator comprising an electrical component which when driven by a driving oscillation displays a rapid rate of current rise corresponding to a steep leading edge and thereby being suitable for the production of a high harmonic content; and, d) the harmonic generator is coupled to both electric conductors of the heating element (3) for the excitation of said element (3) in order to emit a spectrum of vibrations in the natural molecular frequency ranges.
