Definitions
- the invention relates to the use of at least in essential oxygen free, dendritic and uncoated copper for the galvanic coating of Pressure cylinders.
- the chrome layer and the copper layer removed from the impression cylinder for example by Turning can be done.
- a "coppering" of the impression cylinder to the Renew the useful copper layer, into which the next one Image and text information is engraved. Then follows the chrome plating and another print.
- the coppering is typically done by galvanic Coating the impression cylinder in a bath. That kind of Coating is generally known.
- the one with the copper forms the cathode, while the copper is fed to the bath via the anode.
- the bath can be a copper sulfate solution, for example included, improving the conductivity of the Bad sulfuric acid can be added.
- the copper sulfate dissociates in the water, the molecules become split into ions, it is then after the dissociation positively charged copper ions (cations) and negatively charged Sulfate ions (anions). As for sulfuric acid, so it dissociates into hydrogen ions (cations) and Sulfate ions (anions).
- the hydrogen ions migrate during electrolysis Cathode, release their charge there and escape as molecular hydrogen (with the voltage set correctly only to a small extent). Copper ions dissolve at the anode off and go into solution. These copper ions migrate to Cathode, deposit there as copper and become discharged.
- the pressure cylinder to be coated becomes the cathode used and the copper fed through the anode, so it is immediately understand that this is copper plating a printing cylinder can take place. That kind of has galvanic coating of printing cylinders with copper established itself particularly in gravure printing.
- the copper regularly used for this has one Oxygen content typically around 180-300 ppm Structure of this copper has an onion skin shape crystalline orientation on, and the copper is - production-related - with a wax layer overdrawn.
- the invention seeks to remedy this. It is therefore one Object of the invention to propose measures that the significantly reduce the above problems.
- the copper is produced using a casting wire production process is manufactured in which the Pouring wire is poured upwards, and when it is in Cast wire sections crushed is fed to the bath.
- a casting wire production process is manufactured in which the Pouring wire is poured upwards, and when it is in Cast wire sections crushed is fed to the bath.
- Such at least essentially oxygen-free You can find dendritic and uncoated copper in a particularly reliable manner after a Manufacture upward casting process.
- Such copper will for example under the trade name TOP ROD from the Nordré Affinerie AG, Hamburg, Federal Republic Germany, manufactured and sold in wire form.
- the copper is fed into the bath in cast wire sections insofar cheap because in this way the surface of the Overall copper is larger than that of one one-piece plate or a longer piece of wire what to a very uniform structure of the useful copper layer leads.
- the measure has a particularly advantageous effect if Copper is used in which the oxygen content of the Copper is less than 5 ppm, in particular less than or equal to 3 ppm.
- copper with such a low Oxygen content (you can practically get here from oxygen-free copper) either finds one extremely little or no sludge formation, which is particularly beneficial on the wear of the stylus affects, as already described above.
- Fig. 1 is a section from a longitudinal section through shown a printing cylinder 1, as in, for example Gravure printing is used.
- a core 10 e.g. made of steel
- the copper layer 11 consists of at least one essential oxygen free, dendritic and uncoated copper (i.e. it is not manufacturing-related wax layer or the like on the outside copper present).
- the useful copper layer 11 is through a coating 12 e.g. Protected from chrome to the increase mechanical resistance, abrasion when Printing is reduced to almost zero.
- the coating 12 and the Useful copper layer 11 removed, e.g. mechanically and way (e.g. by turning). Is the old one Removed useful copper layer 11, a new one Useful copper layer 11 galvanically in still to be described Applied to the core 10, the next image-text template engraved and with a new chrome cover 12 Mistake. Then the printing cylinder 1 can again print are used.
- a galvanic bath 2 is shown schematically in FIG which the useful copper layer 11 (Fig. 1) galvanically on the Core 10 (Fig. 1) of the impression cylinder 1 can be applied can.
- the anode 3 and the cathode 4 are from a source 5 the respective potential held and with that for it required charge supplied.
- the cathode 4 is the one to be coated Printing cylinder 1 or its core 10 with the Base copper layer 11a (Fig. 1) is formed.
- the liquid F the bath can consist of high-purity water, in which Copper sulfate is dissolved, or to improve the The liquid F also becomes sulfuric acid added, as already described in the introduction.
- the anode 3 can, for example, an anode shell 30 (e.g. made of titanium), which is open at the top and in which is made of cast wire sections 32 (so-called "clippings"), which are used for coating Copper ions can get into the liquid F and themselves can then deposit on the cathode 4 as copper.
- anode shell 30 e.g. made of titanium
- clippings cast wire sections 32
- Copper ions can get into the liquid F and themselves can then deposit on the cathode 4 as copper.
- Dissociation takes place in the liquid F.
- the copper sulfate molecules 6 (CuSO 4 ) dissociate into copper ions 7 (Cu ++ ) cations - on the one hand and sulfate ions 8 (SO 4 - ) on the other hand - anions.
- the copper ions 7 (Cu ++ ) migrate to the cathode 4, which is formed by the pressure cylinder 1, and accumulate there and form the useful copper layer 11 (FIG . 1).
- the "replenishment" of copper ions comes from the casting wire sections 32. From these, positively charged copper ions 7 (Cu ++ ) are released, which then pass through the liquid F to the cathode 4 and accumulate there and so on, whereby the useful copper layer 11 is gradually built up becomes.
- the cast wire sections 32 used can be one cylindrical or other geometric shape (e.g. spherical or produced by a forming process ovoid shape) and have at least one in essential oxygen-free copper, which in low Mass may contain other elements, preferably through Upward casting made. This copper is from his The structure is dendritic and is uncoated.
- copper can also contain: Up to 2 ppm lead, up to up to 1 ppm bismuth, up to 1 ppm arsenic, up to 2 ppm antimony, up to 1 ppm tin, up to 3 ppm zinc, up to 6 ppm iron, up to 5 ppm nickel, up to 12 ppm silver, up to 1 ppm Selenium, up to 1 ppm tellurium, up to 6 ppm sulfur.
- lead up to up to 1 ppm bismuth, up to 1 ppm arsenic, up to 2 ppm antimony, up to 1 ppm tin, up to 3 ppm zinc, up to 6 ppm iron, up to 5 ppm nickel, up to 12 ppm silver, up to 1 ppm Selenium, up to 1 ppm tellurium, up to 6 ppm sulfur.
- the oxygen content is in particular less than 5 ppm, very specifically even less than 3 ppm. This leads to there is no sludge formation in the galvanic bath and thereby the stylus when engraving the image-text template in the useful copper layer in use for much longer can stay.
- Such at least substantially oxygen-free copper is for example under the name "TOP-ROD” at the Nordré Affinerie AG, Hamburg, Federal Republic Germany, available. It is made in a special way and Made by using a copper tip made from a protruding mold located above a copper bath, is immersed in the bath. At the top lies Copper from the copper bath on and solidifies. The copper tip compared to other wire casting relatively slow feed rate a channel extending upwards through the mold drawn, cooling along the canal after a given temperature scheme.
- the wire thus produced has the desired one dendritic structure, as explained above in essentially oxygen-free and without coating (e.g. Wax), whereas this is the conventional way manufactured copper wire by the manufacturing process is conditionally the case. In contrast, that shows.
- made copper typically also a very significant oxygen content, typically in the range of about 180-300 ppm, its structure is helical crystalline.
- oxygen-free, dendritic and uncoated copper does not come, causing the diamond stylus to engrave the Image text template in the useful copper layer of the Printing cylinders can remain in use significantly longer.

- erhöhen die Gefahr von Fehlstellen in der Druckform und
- minimieren die Standzeit der bei der Gravur eingesetzten Diamantstichel, die sich durch solche Einschlüsse schneller abnutzen und früher ausgewechselt werden müssen. Diese Dinge führen zu einem erhöhten Zeit- und Kostenaufwand.
- Strukturen während der Gravur hervorgerufen werden können, bzw.
- die Verchromung in entsprechenden Bereichen verhindert werden kann. Auch diese Dinge führen zu einem erhöhten Kostenaufwand.
