Description

Verfahren zum Polieren vbn Kleinmetallgegenständen Beim Polieren von Kleinmetallteilen im Rollfaß u. dgl. wurde bisher in zwei Arbeitsgängen gearbeitet, und zwar wurden die Teile zuerst in einer alkalischen Lösung, beispiels«,eise in einer Sodalösung, entfettet, danach mit Wasser gespült und in einem zweiten Arbeitsgang zwecks Entfernung der Metalloxyde in einer sauren Lösung, z. B. in einer Alkalibisulfatlösung, behandelt.Method of polishing small metal objects When polishing Small metal parts in the barrel and the like have so far been worked in two steps, namely, the parts were first placed in an alkaline solution, for example «, ice in a soda solution, degreased, then rinsed with water and in a second step for the purpose of removing the metal oxides in an acidic solution, e.g. B. in an alkali bisulphate solution, treated.

Es wurde nun gefunden, daß man das Polieren von Gegenständen aus Eisen, Eisenlegierungen, Messing usw. im Rollfall u. dgl. auch in einem einzigen Arbeitsgang ausführen kann, wenn man ein sauer reagierendes Bad verwendet, das aus einer Lösung eines sauren Salzes bzw. einer Säure, mindestens einem organischen wasserunlöslichen bzw. -schwerlöslichen Lösungsmittel und einem säurebeständigen kapillaraktiven Stoff, beispielsweise einem säurebeständigen Netz- bzw. Emulgiermittel, besteht.It has now been found that the polishing of objects made of iron, Iron alloys, brass, etc. in the case of rolling and the like. Also in a single operation can run if you use an acidic bath that is made from a solution an acid salt or an acid, at least one organic water-insoluble or sparingly soluble solvents and an acid-resistant capillary-active substance, for example an acid-resistant wetting agent or emulsifying agent.

Auf diese Weise kann leicht erreicht werden, daß kein Schaum entsteht und keine Verminderung der Fall- und Reibungsintensität der Eisenteile auftritt, die die Polierwirkung herabsetzen würde.In this way it can easily be achieved that no foam is produced and there is no reduction in the intensity of falling and friction between the iron parts, which would reduce the polishing effect.

Als Lösungsmittel kommen solche in Betracht, die sich in Wasser nicht oder nur schwer lösen, beispielsweise Benzin, Benzol u. dgl. Beispiel Zum Polieren von Kleineisenteilen wird eine 2 %ige Lösung von 8 5 % Natriumbisulfat, io % Pineöl und z % der Stilfonierungsprodukte von Fettalkoholen, die durch Rezluktion natürlich vorkommender Fettsäuregemische gewonnen sind, verwendet. Statt Pineöl können auch Mischungen von Pineöl mit anderen bekannten Lösungsmitteln verwendet werden. Die Entfettung und Entrostung der Eisenteile erfolgt bei gewöhnlicher Temperatur und ist in i Stunde beendet.Suitable solvents are those which are not in water or difficult to dissolve, for example gasoline, benzene and the like. For example, for polishing a 2% solution of 8 5% sodium bisulphate, 10% pine oil is used for small iron parts and z% of the stilfonation products of fatty alcohols naturally produced by recirculation occurring fatty acid mixtures are used. You can also use pine oil instead Mixtures of pine oil with other known solvents can be used. the The iron parts are degreased and rusted at normal temperature and finished in 1 hour.
