Definitions

  • This invention relates to a method of manufacturing an improved electric heating film.
  • the method of manufacturing an electric heating film according to the present invention mainly comprises steps of preparing a mixture 10 by mixing a plurality of compounds, mixing the mixture with medium materials to form a liquid material, cleaning and drying the base material, atomizing the liquid material, and coating the base material 12.
  • the steps of the manufacturing method will be described in detail hereinafter.
  • Tin oxide is the easiest to obtain and lowest in cost and so it is used as the main material.
  • oxides are non-conductive substances and will become semi-conductors when incorporated of certain impurities.
  • impurities in weight has been added into the oxides so as to modify the resistivity of the mixture thereby controlling the heat evolved from the mixture.
  • the medium material may be water, methyl alcohol, ethyl alcohol, hydrochloric acid, ethylamine, ...etc.
  • the mixture and the medium material are stirred well to form a liquid material which is then filtered so as to remove the undesired matter therein.
  • the base material 12 is to coated with the electric heating film according to the present invention.
  • the base material 12 may be in the shape of a tube, a panel, or a beehive 21 shown in FIG. 3.
  • the base material 12 may be conveniently made of quartz, glass, porcelain, mica or similar material with high temperature resistance and low expansion coefficient.
  • the base material 12 must be inspected, washed with clean soft water and dilute hydrochloric acid, and dried before use.
  • the base material into a heating furnace (not shown) and heated to 400-800 degrees centigrade for 5-10 minutes so as to activate the surface of the base material. Then, mix the liquid material with air at a certain proportion and spray them into the heating furnace by means of a compressor at an air pressure of 2.0 kg/cm3 hence atomizing and dissolving the liquid material into ions. Thereafter, let the ions be accumulated and evenly coated on the base material 12 to a thickness of 3-300 ⁇ thereby providing the base material 12 with a layer of electric heating film according to the present invention. Thereafter, the base material in the shape of a beehive is coated with a layer of silver glue 21 with a temperature resistance of higher than 850 degrees centigrade and a resistance lesser than 0.3 ohm.
  • the general time for atomizing the liquid material is about 10-30 minutes and depends on the thickness of the film designed to be coated on the base material and the power of the heating furnace.
  • the electric heating film coated on the base material 12 is very thin, the electric current consumed is very small and the heat energy is transmitted from inside to outside, the temperature difference between the inside and outside will be small and it is unnecessary to worry about explosion.
  • the temperature evolved from the electric heating film can reach 700 degrees centigrade. Further, no obvious flame will be produced when the temperature is lower 500 degrees centigrade.
  • the electric heating will consume less than 70 per cent of electricity required by the prior art.
  • FIG. 5 illustrates the relationship between the power and the temperature of the present invention.
  • the power consumption of the present invention is much lower than that required by the prior art.
  • FIG. 6 shows the relationship between the refractive index and the wave length of the present invention.
  • the heat energy of the present invention includes far infrared energy and radiating energy and 80% of the heat energy comes from the far infrared energy.
