Description

Weichlot Die meisten Weichlote bestehen zumeist zu 40 oder melu Prozent aus Zinn. Da Zinn teurer ist als Blei, verteuert das Zinn wesentlich das Lot.Soft solders Most soft solders consist mostly of 40 or melu percent made of tin. Since tin is more expensive than lead, the tin makes the solder much more expensive.

Das Lot nach :der Erfindung besteht zumindest zu 99% aus Blei und ist demzufolge wesentlich billiger als die zinnhaltigen Lote. Es soll zum Löten und Verbleien von Metallen und Metallegierungen dienen, die mit Schwefel eine cherriische Verbindung eingehen. Auch Blei kann damit gelötet werden, was bisher nicht möglich war.The solder according to: the invention consists of at least 99% lead and is therefore much cheaper than the tin-containing solders. It's supposed to be soldered and leading of metals and metal alloys, which have a chemical character with sulfur Enter into connection. Lead can also be soldered with it, which was previously not possible was.

Das Lot wird hergestellt durch Einrühren eines geringen Prozentsatzes (unter i % ) Schwefel in die flüssige Bleimasse. Ein Teil des zugegebenen Schwefels verbindet sich mit einem Teil des Bleies zu Bleiglanz, die restliche Metallmasse., in Stangen gegossen, bildet .das Lot. Durch dieses Verfahren soll eine Verbilligung von Loten erreicht werden, da billiges inländisches Metall ohne Zusatz -teurer ausländischer Metallre als Lot und zum Verbleien von Metallen und Metallegierungen verwendet werden kann.The solder is made by stirring in a small percentage (less than i%) sulfur in the liquid lead mass. Part of the added sulfur combines with part of the lead to form galena, the rest of the metal mass., Poured into bars, forms the solder. This procedure is intended to reduce the price can be achieved by solders, as cheap domestic metal without the addition of expensive foreign metals Metallre can be used as solder and to lead metals and metal alloys can.

Es ist bereits bekannt, Weichlote mit großem Bleigehalt durch Zusatz von Phosphor oder Arsenik, teilweise unter Anwendung von. 5oo bis 6oo Atm. Druck, herzustellen. Diese Verfahren haben ;aber den Nachteil, daß das Lot in verschiedenen Arbeitsgängen hergestellt werden muß, die teilweise mehrere Stunden in Anspruch nehmen. Der @erforderliche Druck von 5oo bis 6oo Atm. ist der fabrikmäßigen Herstellung der Lote wegen der durch den Dmuck bedingten Dimensionen der Schmelzgefäße hinderlich. Die Verm@ei-@dung von Druckerhöhungen bei der Herstellung bedeutet leine wesentliche Verbilligung ,der Fabrikationseinrichtungen. Auch ist der Gehalt der Lote an giftigen Stoffen bei der Herstellung und bei der Verarbeitung der Lote hinderlich.It is already known to add soft solders with a large lead content of phosphorus or arsenic, sometimes with the use of. 500 to 600 atm. Pressure, to manufacture. These methods have the disadvantage, however, that the solder is in different Operations must be made, some of which take several hours to take. The @required pressure of 5oo to 6oo atm. is factory-made the plumb bob because of the dimensions of the melting vessels caused by the pressure. Avoidance of pressure increases during manufacture means There is no substantial reduction in the price of the manufacturing facilities. Also is the salary the solders of toxic substances in the manufacture and processing of the solders obstructive.

Das Lot nach der Erfindung wird in einem Arbeitsgang durch Einrühren eines geringen Prozentsatzes Schwefel in die flüssige Bleimasse ohne Druck in wenig Zeit mehr hergestellt, als Blei zum Schmelzen benötigt. Die Herstellung ist daher denkbar einfach und erfordert wenig Zeit. Das Lot ist wetterbeständig, es behält die Farbe des Bleies bei und benötigt keinen Zusatz hellmachender Metalle.The solder according to the invention is stirred in in one operation a small percentage of sulfur in the liquid lead mass without pressure in little Produced more time than it takes lead to melt it. The manufacture is therefore very easy and takes little time. The solder is weatherproof, it retains the color of the lead and does not require the addition of brightening metals.
