Definitions

  • most heated glazing such as that forming the rear window of motor vehicles, includes one or more networks of wires or conductive tapes incorporated into the glass of the telescope or applied to its surface, these wires or ribbons constituting as many electrical resistors intended to be attached to the terminals of the vehicle battery and thus produce the heat necessary for the melting of the frost covering the telescope in order to restore its original transparency.
  • the resistive elements consist of conductive coatings, generally coatings of metal oxides, such as tin oxide. , deposited by vaporization, as for example in patents US-A-2,564,677 and 2,833,902, or also by the technique called CVD, as in the case of patent FR-A-1,165,645 or European application EP-A-0.023.471 already cited.
  • the deposited metallic coating is protected, the glazing being in the form of a “sandwich” structure, this coating being covered by one or more sheets of transparent material, while, in others, the coating remains bare.
  • these coatings have, at the same time, high transparency, high mechanical hardness and sufficient flexibility to allow the production of glazing of various shapes, without continuity solution for the layer of Sn0 2 '
  • the object of the present invention is to allow the production of heated glazing units having a plurality of resistive pads intended to be connected to a source of supply current and each consisting of a coating of Sn0 2 ' deposited by CVD on at least one face. of a glass plate brought to high temperature, glazing whose ranges have, in section, dimensions remaining both particularly precise and constant, despite the particularly high speed at which such manufacture must be able to be carried out, while guaranteeing the 'Obtaining conductive pads of sufficiently low resistivity so that the glazings thus obtained can, in use, be defrosted fairly quickly by feeding from energy sources of limited power, such as the batteries with which motor vehicles are usually fitted.
  • the invention proposes to make use of a device intended for the formation of said resistive pads on a glass plate, including a series of nozzles each comprising, as in the device described in patent DD-A-109,033, two coaxial nozzles directed towards the face of the glazing to be coated by said areas and intended to be supplied by separate reagents, from nozzle to nozzle, the combination of which generates the formation of said coating, means for relatively moving the glass plate and the nozzles so that each coating is formed on renewed areas of said face of the plate, thereby creating said resistive areas, and a device for the evacuation, by suction, of gases from the combination of said reagents, comprising a suction head of these gases, arranged near each nozzle and connected to a network for removing said gases.
  • each suction head is constituted by a tubular bell surrounding the respective nozzle, coaxial therewith, and opening at a level corresponding substantially to that of the opening of the nozzles of this nozzle, the opening of said bell having a diameter of value substantially equal to the desired width for the range resistive to form by the nozzle considered so that the reaction for forming the coating of Sn0 2 takes place exclusively in the region of the glass plate limited, at all times, by the periphery of the opening of the bell of each nozzle .
  • the implementation of such a device makes it possible to obtain a particularly efficient heating glazing of the type mentioned above, which is characterized in that the thickness of the coating constituting each range is 2.5 ⁇ m, that its resistivity is 10- 3 ohm.cm and the extent of the part of the glazing covered by the resistive pads is 4 times less than the extent of the rest of this glazing.
  • the device visible in fig. 1 comprises three nozzles 1, 2 and 3, each comprising two concentric nozzles designated respectively by the letters a and b.
  • the set of central nozzles marked a is connected by a general piping 4, distribution, to a bubbler container 5 containing one of the reagents 6 allowing the formation of the transparent conductive layer; in this case, this reagent is SnCl 4 .
  • the nozzles b are connected by a distribution circuit 7 to a container 8 containing a second reagent 9, in this case aqueous methanol.
  • the device also comprises conduits for supplying a carrier gas, respectively 10 and 11, immersed in the reactive liquids, this gas being intended to vaporize a part of these.
  • Evacuation chambers collect the by-products of the coating reaction, in this case HCI, and direct them towards a chimney 15.
  • the device described is intended to coat the upper face d 'a glass plate 16 by a layer of SnO 2 , this plate being supported by rollers 17 so as to ensure its displacement perpendicular to the flow of gas flows.
  • the enclosures 12, 13 and 14 closely surround the nozzles 1, 2 and 3, respectively, and their size, as well as the suction depression which prevails therein, determine the field of dispersion on the plate 16 of gases from said nozzles and, thereby, the width of said conductive areas.
  • the device described operates as follows: the glass sheet 16 is heated to a relatively high temperature, for example 500 to 600 ° C., by means of an oven not shown in the drawing, and is progressively conveyed, by rollers 17, in look at the outlet of the nozzles 1, 2 and 3.
  • a carrier gas for example an H 2 / N 2 mixture, is introduced at a predetermined rate, so that, by bubbling, this gas entrains, in the form of vapors, the reactants 6 and 9, these simultaneously opening out orifices a and b of each of the nozzles.
  • a plate of this glazing 60 x 30 cm was subjected to a standard icing and defrosting test as follows: At -15 ° C, we sprayed water on the plate, so as to cover it with a thick and absolutely opaque layer of frost. Then the lateral conductive paint strips were connected to the terminals of a 12 V direct current source and it was found that, at the temperature of -15 ° C, the conductive areas became clear in approximately 1 min. which allowed to have a good general vision through the glazing.
