Verfahren zum Entzinnen von Weißblechabfällen mittels Sauerstoffsäuren des Schwefels. Patentiert im Deutschen Reiche vom 12. November 1913 ab.Process for detinning tinplate waste using the oxo acids of sulfur. Patented in the German Empire on November 12, 1913.
Das Verfahren beruht auf der Fähigkeit konzentrierter Schwefelsauerstoffsäuren, das Eisen zu passivieren und somit nicht anzugreifen. Gegenteiliges tritt bekanntlich bei starker Verdünnung ein.The process is based on the ability of concentrated sulfuric oxygen acids that Passivate iron and thus not attack it. As is well known, the opposite occurs strong dilution.
Das Zinn zeigt beim Lösen in Schwefelsauerstoffsäuren gerade umgekehrtes Verhalten.The tin shows exactly the opposite behavior when it dissolves in sulfuric oxygen acids.
Man preßt die Weißblechabfälle zu Paketen und führt sie in Gitterkörben mittels Kranes ίο in Kessel mit konzentrierter Schwefelsäure von etwa 93 Prozent.The tinplate waste is pressed into packages and carried in wire baskets by means of a crane ίο in kettle with concentrated sulfuric acid from about 93 percent.
Nach beendeter Kalt- oder Heißbehandlung wird das Zinnsulfat abgezogen, die Weißblechpakete ausgehoben und sorgfältig gewaschen. After the cold or hot treatment is finished, the tin sulphate is drawn off, the tinplate stacks excavated and carefully washed.
Aus den stark zinnangereicherten Säuren wird das Metall nach irgendeinem der bekannten Verfahren gewonnen.The metal is converted from the strongly tin-enriched acids according to any of the known ones Procedure won.
