Lötmittel zum Weichlöten. Patentiert im Deutschen Reiche vom 9. Juli 1914 ab.Solder for soft soldering. Patented in the German Empire on July 9, 1914.
Gegenstand der Erfindung ist die Verwendung von zitronensaurem Ammon als Lötmittel für Weichlötung.The invention relates to the use of citric acid ammonium as a solder for soft soldering.
Es ist bereits vorgeschlagen worden, Zitronensäure als Zusatz zu einem Lötmittel zu verwenden; jedoch handelte es sich hierbei um einen geringfügigen Zusatz zu einem Härtlötmittel, dessen Wirkung bei Temperaturen verlangt wird, bei welchen Zitronensäure längstIt has already been suggested to use citric acid as an additive to a solder use; however, this was a minor addition to a hardening solder, whose effect is required at temperatures at which citric acid has long been
ίο vollkommen zersetzt ist. Überdies ist ein beträchtlicher Unterschied zwischen der Wirkung reiner Zitronensäure und ihrem Ammonsalze bei der Anwendung nach der Erfindung bemerkbar. ίο is completely decomposed. Moreover, it is a considerable one Difference between the effect of pure citric acid and its ammonium salts when used according to the invention is noticeable.
Das zitronensaure Ammon wird entweder als Pulver oder wäßrige Lösung oder mit Glyzerin gemischt verwendet. Eine zweckmäßige Masse ist z. B. 1 Teil zitronensaures Ammon in der Wärme in 2 Teilen Glyzerin gelöst. Zusatz einer kleinen Menge Salizylsäure ist nützlich.The citric acid ammonium is available either as a powder or aqueous solution or with Glycerine used mixed. An appropriate mass is, for. B. 1 part lemon acid Ammonia dissolved in 2 parts of glycerine in the heat. Added a small amount of salicylic acid is useful.
Im Gegensatz zu den bekannten chlorhaltigen Weichlötmitteln, auch Kolophonium u. dgl., greifen die Rückstände des zitronensauren Ammons die verwendeten Metalle, selbst Eisen, nicht an.In contrast to the well-known chlorine-containing soft soldering agents, including rosin and the like, the residues of the lemon acid ammonium attack the metals used, even iron, not on.
