Definitions

  • the invention relates to methods for producing a protective layer which limits copper solubility in water on the inner surface of copper pipes.
  • DE 195 33 410 A1 also includes a process for producing a protective layer which limits copper solubility in water from malachite (CuCO 3 Cu [OH] 2 ) or atakamite (CuCl 2 3Cu [OH] 2 ).
  • a synthetic drawing agent modified with CO 2 or with substances that form CO 2 and O 2 is used, to which halogen-organic or other chlorine / halogen-containing compounds have been added.
  • the invention is therefore based on the object of enabling a technically efficient production of a protective layer on the inner surface of copper pipes.
  • a first solution to this problem consists in the measures of claim 1, with which a protective layer of basic copper carbonates is produced on the inner surface of copper pipes.
  • the main idea is the oxidative treatment of the inner surface of the pipe with solutions of oxidants and carbonate-containing salts at elevated temperatures.
  • the inner surface of the copper tube is expediently cleaned. This is particularly useful for degreasing.
  • the degreasing can be carried out chemically by treatment with commercially available degreasing agents or by pickling, for example with sulfuric acid or nitric acid. Mechanical treatment such as sandblasting can also be carried out.
  • the tube is then filled with an aqueous oxidation solution.
  • the oxidation solution remains in the copper tube for a period between 0.1 hours and 48 hours, with a temperature between 10 ° C and 95 ° C is maintained.
  • the copper tube is then rinsed with water and then dried. To remove loosely adhering copper carbonate particles, the tube can be blown out with compressed air.
  • the oxidizing solution contains oxidants and salts of carbonic acid as well as optional salts of other acids.
  • the pH of the oxidation solution is in the range between 3 and 12.
  • the consistency of the oxidation solution can be changed by adding wetting agents or thickeners and adapted to the respective conditions of use.
  • wetting agents and / or thickeners of a known type are used. They are added to the oxidation solution up to a proportion of 50 g / l each.
  • an oxidation solution is used from oxidants such as hydrogen peroxide, potassium permanganate, potassium chlorate, sodium chlorite or mixtures thereof in a concentration between 5 g / l and 500 g / l and salts of carbonic acid such as sodium carbonate, potassium carbonate, ammonium carbonate, copper (I ) carbonate, copper (II) carbonate, sodium hydrogen carbonate, potassium hydrogen carbonate, ammonium hydrogen carbonate or mixtures thereof in a concentration between 5 g / l and 500 g / l.
  • oxidants such as hydrogen peroxide, potassium permanganate, potassium chlorate, sodium chlorite or mixtures thereof in a concentration between 5 g / l and 500 g / l and salts of carbonic acid such as sodium carbonate, potassium carbonate, ammonium carbonate, copper (I ) carbonate, copper (II) carbonate, sodium hydrogen carbonate, potassium hydrogen carbonate, ammonium hydrogen carbonate or mixtures thereof in a concentration between 5 g
  • the protective layer produced according to the invention reduces the release of copper ions, particularly in carbonated and / or acidic drinking water.
  • the factory production ensures above all a copper ion release in the first years after commissioning a new copper pipe installation.
  • a second solution to the problem consists in a method in which the inner surface of the copper tube is wetted with a copper ammonium chloride solution and then brought into contact with an oxygen-containing gas.
  • the inner surface of the copper pipe should also first be cleaned and degreased.
  • the copper ammonium chloride solution preferably consists of distilled water in which 80 g copper ammonium chloride are dissolved per liter. To wet the inner surface of the copper tube, it is advisable to rinse the copper tube with the copper ammonium chloride solution, a contact time between 1 sec and 10 sec, preferably between 1 sec and 3 sec, being sufficient (claim 7).
  • Air or other oxygen-containing gases can be used as the reaction gas.
  • the wetted inner surface is brought into contact with an oxygen-containing gas for a period between 10 min and 20 min at a temperature between 15 ° C and 70 ° C.
  • a contact time of 15 minutes and a temperature of 20 ° C are considered to be particularly advantageous.
  • the inner surface of the tube is allowed to dry. This can be accelerated by hot air (claim 9), preferably at a temperature of 65 ° C, which is passed through the copper pipes by means of a fan.
  • Non-adhering particles of the protective layer can additionally be cleaned mechanically, in particular by blowing them out with compressed air.
  • the protective layer is preferably deposited from an electrolyte solution in the form of a mixture of water, sodium hydrogen carbonate NaHCO 3 and sodium sulfate Na 2 SO 4 , the proportion of sodium hydrogen carbonate being 60 g and the proportion of sodium sulfate being 40 g per liter of water.
  • the electrolytic deposition can be carried out using an inner electrode, for example in the form of a wire. After the copper tube has been filled with the electrolyte solution, the copper tube is polarized anodically and the inner electrode is cathodically polarized. It is also possible to apply the electrodes at the beginning or end of the pipe.
  • the indicated solutions to the problem on which the invention is based are based on the idea of producing a protective layer on the inner surface of a copper tube in the factory.
  • the technological connection consists of surface corrosion, which is defined in the factory and leads to the formation of protective layers from copper corrosion products. This ensures a reliable minimization of the copper ion release to the drinking water.
