Description

Löt-, Schweiß-, Fluß- oder Schmelzmittel Es wurde gefunden, daß Polyphosphate sich vorzüglich als Löt-, Schweiß-, Fluß- oder Schmelzmittel für Metalle und Metallegierungen, z. B. Aluminium, Kupfer, Nickel, Bronze, Messing, Neusilber usw., eignen.Soldering, welding, fluxing or fluxing agents It has been found that polyphosphates excellent as a soldering, welding, flux or melting agent for metals and metal alloys, z. B. aluminum, copper, nickel, bronze, brass, nickel silver, etc. are suitable.

Unter Polyphosphaten sind Salze zu verstehen, die sich formelmäßig von solchen Säuren ableiten, die in bezug auf das Verhältnis H20: P205 zwischen der Pyrophosphorsäure und der Metaphosphorsäure liegen. Unter den benutzbaren Polyphosphaten sind insbesondere die alkalisch oder neutral reagierenden Alkalipolyphosphate von der Formel Na 5P301., NaeP4013 od. dgl. geeignet. In einigen Fällen können auch die sauer reagierenden Alkalipolyphosphate, wie z. B. Na12P1,031, Verwendung finden.Polyphosphates are salts that have a formula derive from those acids which, in terms of the ratio H20: P205, are between pyrophosphoric acid and metaphosphoric acid. Among the usable polyphosphates are in particular the alkaline or neutrally reacting alkali polyphosphates of of the formula Na 5P301., NaeP4013 or the like. Suitable. In some cases you can also the acidic reacting alkali polyphosphates, such as. B. Na12P1,031, use.

Gegenüber den als Löt- oder Schweißmittel oder als Zusatz zu solchen bekannten Salzen, die sich von anderen Säuren des Phosphors ableiten, insbesondere gegenüber den Ortho- und Perphosphaten, weisen die Polyphosphate den Vorteil auf, daß sie in der Lage sind, unter Komplexbildung die verschiedensten Oxyde anzulagern, und daß die Möglichkeit gegeben ist, das Verhältnis von basischem Oxyd zu P205 innerhal,l> weiter Grenzen beliebig zu wählen und so' Mittel herzustellen, die im Schmelzfluß auf metallische Oberflächen verschieden ,einwirken; man hat es so in der Hand, für die verschiedenen Metalle das günstigste auszuwählen.Compared to the soldering or welding material or as an additive to such known salts derived from other acids of phosphorus, in particular compared to orthophosphates and perphosphates, the polyphosphates have the advantage that they are able to accumulate a wide variety of oxides while forming complexes, and that the possibility is given of the relationship between the basic oxide to P205 within, l> further limits to be chosen arbitrarily and thus to produce means, which act differently in the melt flow on metallic surfaces; one has it so at hand to choose the most favorable for the various metals.

Die Polyphosphate können für sich oder im Gemisch mit anderen bekannten Mitteln verwendet werden, beispielsweise in Lötmischungen für Aluminium, in Fluß- und Reinigungsmitteln zum Schmelzen von Metallen, gegebenenfalls unter Zusatz von Borax oder Borsäure oder anderen bekannten Flußmitteln oder Schlackenbildnern, wie Kieselsäure, Silicate oder Alkalien, oder in Reduktionsmitteln, wie Ferrocyaniden oder anderen desoxydierend wirkenden Stoffen.The polyphosphates can be known alone or in admixture with others Agents are used, for example in soldering mixes for aluminum, in flux and cleaning agents for melting metals, optionally with the addition of Borax or boric acid or other known fluxes or slag forming agents such as Silicic acid, silicates or alkalis, or in reducing agents such as ferrocyanides or other deoxidizing substances.
