besonders Blei.especially lead.
Aus einer concentrirten Lösung von Chlorzinn des Handels (Zinnchlorür und Zinnchlorid) wird das Zinn durch phosphorsaures Natron niedergeschlagen. Dieser Niederschlag (ein Gemenge von phosphorsaurem Zinnoxydulhydrat und phosphorsaurem Zinnoxydhydrat) wird gewaschen und in concentrirter Aetznatronlauge wieder gelöst, nachdem noch ca. 5 pCt. Aetzammoniak der Lösung zugesetzt worden.From a concentrated solution of tin-chlorine on the market (tin chloride and tin chloride) the tin is precipitated by sodium phosphate. This precipitate (a mixture of phosphoric acid tin oxide hydrate and phosphoric acid tin oxide hydrate) is washed and dissolved again in concentrated caustic soda, after about 5 pCt. Caustic ammonia has been added to the solution.
. Die Lösung wird darauf mit destillirtem Wasser nach Mafsgabe der Gröfse der Oberfläche der zu verzinnenden Objecte und der Stärke des galvanischen Stromes verdünnt.. The solution is then mixed with distilled water according to the size of the surface the objects to be tinned and the strength of the galvanic current.
Die Anwendung ist eine gewöhnliche.The application is a common one.
Alle bisher bekannten Zusammensetzungen von Lösungen zum galvanischen Verzinnen schlagen das metallische Zinn mehr oder weniger schwammig nieder. Dies ist bei der Verzinnung von Blei am meisten der Fall, und haftet entweder das niedergeschlagene Metall wenig, oder es ist zu spröde und springt beim Biegen des Bleies ab.All previously known compositions of solutions for electroplating knock down the metallic tin more or less spongy. This is with the Tin plating of lead most of the time, and either adheres to the deposited metal little, or it is too brittle and pops off when the lead is bent.
Durch die Zusammensetzung der oben beschriebenen Lösung und den erwähnten Zusatz von Aetzammoniak wird eine zu schnelle Ausscheidung des Zinnes vermieden und dasselbe in weifserer und glänzenderer Farbe bei seiner ursprünglichen Biegsamkeit niedergeschlagen, sofern die Stromstärke entsprechend regulirt ist.Through the composition of the solution described above and the additive mentioned caustic ammonia prevents the tin from excreting too quickly, and the same cast down in whiter and brighter color at its original flexibility, as long as the current intensity is regulated accordingly.
