Definitions

  • the present invention relates to a method for coating a sanitary component.
  • the sanitary component can be, for example, a fitting housing for a sanitary fitting, which is used to provide a liquid as required, for example in a washbasin, kitchen sink, shower and/or bathtub.
  • Sanitary components can have liquid channels, by means of which the liquid, for example water, can be fed to an outlet opening of the sanitary component or the sanitary fitting.
  • the liquid comes into contact with a material of the sanitary component, so that components of the material, in particular alloy components of the material, such as lead, can be absorbed by the liquid.
  • these components can be harmful to health, this is not desirable.
  • the object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to specify a method for coating a sanitary component with which the release of components of the material of the sanitary component to the liquid can at least be reduced. This object is achieved with a method according to the features of the independent patent claim. Further advantageous embodiments of the invention are specified in the dependent formu profiled claims.
  • a method for coating a sanitary component which has at least the following steps: a) providing the sanitary component, the sanitary component having at least one liquid channel; and b) at least partially coating an inner surface of the at least one liquid channel with a coating, the coating having at least one layer comprising copper.
  • the sanitary component can be, for example, a fitting housing for a sanitary fitting.
  • a sanitary fitting is used in particular to provide a liquid, in particular water, on a washbasin, kitchen sink, shower and/or bathtub as required.
  • the sanitary fitting is used in particular for removing or dispensing the liquid.
  • the sanitary component can consist at least partially of metal and/or be designed in the manner of a cast component.
  • the sanitary component or a material of the sanitary component can contain lead, for example as an alloying element.
  • the sanitary component can consist at least partially of plastic and/or be designed in the manner of a plastic injection molded part.
  • the sanitary fitting can include at least one actuator for a water temperature and/or a removal quantity of the water.
  • the sanitary fitting can be used in a user's field of vision, so that the sanitary component can be designed in the manner of a surface plaster component.
  • the sanitary component can also be designed as a flush-mounted component.
  • flush-mounted components can be built into a building wall, for example, so that they are generally not visible to a user (in a built-in state).
  • the sanitary component has at least one liquid channel for the liquid.
  • the liquid fluid channel can in particular be formed by the sanitary component and/or in the sanitary component.
  • the at least one liquid channel is in particular not a separate component of the sanitary component. Instead, the at least one liquid channel can be designed in one piece with the sanitary component.
  • the at least one liquid channel can be designed as a cavity in the sanitary component.
  • the at least one liquid channel can be designed at least partially in the manner of a bore. Furthermore, the at least one liquid channel can, for example, at least partially extend through an outlet of the sanitary component or the fitting housing. In addition, the at least one liquid channel can extend, for example, from a receiving space for at least one functional component of the sanitary component to the outlet opening. In addition, the at least one liquid channel can be delimited at least partially by the sanitary component or by a material of the sanitary component. By means of the liquid channel, the liquid can be fed, for example, to an outlet opening of the sanitary component or the sanitary fitting. In this case, the liquid can come into contact with a material of the sanitary component in particular.
  • the sanitary component is provided. This can include the manufacture of the sanitary component (uncoated or as a semi-finished product). Step a) can include aligning and/or positioning the sanitary component in an environment in which step b) can then (immediately) be carried out.

  • the coating of the inner surface of the at least one liquid channel can be limited to an area in which the at least one liquid channel opens out on the outer surface of the sanitary component.
  • This area can, for example, have a maximum length of 10 cm (centimeters), preferably a maximum of 5 cm, from the outer surface of the sanitary component along the at least one liquid channel.
  • the coating (produced in step b) has at least one layer which comprises copper.
  • the coating can thus consist of a single layer of copper, which is in particular applied directly to the inner surface of the at least one liquid channel.
  • the coating can be formed from a plurality of layers. In this case, the coating can be a multi-layer system with which, in particular, decorative and/or functional surfaces can be produced.

  • the layer of copper and/or the individual layers of the coating can be deposited electrolytically on the inner surface of the at least one liquid channel and/or the outer surface of the sanitary component. In the area of the coating, contact of the liquid with the material of the sanitary component can be prevented, so that no components of the material of the sanitary component that are harmful to health can be absorbed by the liquid.
  • the sanitary component can be made of copper or a copper alloy.
  • the copper alloy can include zinc, for example.
  • the copper alloy can be brass or bronze.

  • the mass fraction of phosphorus in the nickel-phosphorus alloy is preferably 8% to 14%, particularly preferably 10% to 12%.
  • the second layer of the nickel-phosphorus alloy is in particular deposited electrolytically on the sanitary component.
  • the nickel-phosphorus alloy takes on the function of corrosion protection in particular.
  • the nickel-phosphorus alloy prevents corrosion of the sanitary component to a high degree and thus improves the corrosion properties in particular of decorative coatings with a functional character.
  • the coating (possibly with the exception of the layer made of the nickel-phosphorus alloy) has no further layer which comprises nickel.
  • the coating may include a third layer of chromium.
  • the third layer is formed directly on the second layer.
  • the chromium of the third layer can be deposited from hexavalent or trivalent chromium electrolyte.
  • the coating may include a fourth layer of zirconium compound, chromium compound, or titanium compound. Mixtures of these compounds are also possible in the fifth layer.

  • the purpose of this coating is to create a specific color. For example, this can be used to create red tones, gold tones or a stainless steel look on galvanically deposited chrome layers.
  • the composition of these layers determine the color that is achieved.
  • These layers mostly consist of zirconium nitride (ZrN), titanium nitride (TiN) and/or chromium nitride (CrN) in different proportions.
