Definitions

  • the invention relates to a method for producing a lyophobic layer on the nozzle carrier of a writing instrument working with liquid droplets.
  • the nozzle holder can be provided with a layer on the side mentioned, the surface tension of which is lower than the surface tension of the writing liquid.
  • This lyophobic, i.e. Liquid-repellent layers can consist of polyethylene or polytetrafluoroethylene.
  • polytetrafluoroethylene layers can be produced by sintering on the powdery or dispersed starting material. With this method, it is difficult to control the thickness of the coating. Furthermore, the surface becomes slightly grainy and it is difficult to avoid a partial covering of the nozzle openings.
  • the invention has for its object to provide a layer with the required low surface tension, which is uniform and non-porous, does not cover the nozzle openings, and the thickness of which is easy to control. It must also meet other requirements regarding adhesive strength, abrasion and scratch resistance.
  • the layer of an organic compound is produced directly on the nozzle carrier in a high-frequency, low-pressure glow discharge.
  • the nozzle carriers are placed in a vacuum chamber which, after evacuation, is flowed through with, for example, a fluorine-containing, gaseous compound, a pressure of 10 -2 to 10 mbar being set and maintained.
  • a high-frequency glow discharge is ignited in the chamber mentioned, in the course of which a thin layer of a fluoropolymer is formed on the nozzle carriers.
  • the coupling of the high-frequency energy can take place in a known manner capacitively with the aid of two electrodes located inside or outside the chamber or inductively with the aid of a coil placed around the chamber.
