Description

Verwendung einer Cadmiumlegierung als Füllmasse Die Erfindung bezieht sich auf eine Füllmasse aus Metall zum Ausfüllen. der Vertiefungen in den Blechwänden von Kraftfahrzeugen. Diese Füllmasse soll einen verhältnismäßig niedrigen Schmelzpunkt haben und während. der Erstarrungsdauer, also zwischen ihrem Schmelzpunkt und ihrem Erstarrungspunkt, möglichst knetbar sein. Auch soll ,diese Füllmasse säurebeständig sein und eine gewisse Festigkeit .haben.Use of a cadmium alloy as a filling compound The invention relates on a filler made of metal for filling. of the recesses in the sheet metal walls of motor vehicles. This filling compound should have a relatively low melting point have and during. the duration of solidification, i.e. between their melting point and theirs Freezing point, be kneadable if possible. This filling compound should also be acid-resistant be and have a certain strength.

Bisher hat man als Füllmasse eine Legierung verwendet, .die aus etwa 75%. Blei und etwa 250/0 Zinn bestand. Diese Legierung entspricht den genannten Erfordernissen, jedoch muß die Oberfläche .der Fülltrasse nun nach Einbringung in die Vertiefung mit der Feile und der Bürste bearbeitet werden. Dabei entsteht ein feiner Metallstaub; der wegen seines Gehaltes an Blei für die dabei beschäftigten Arbeiter gesundheitsschädlich ist. Man könnte diesen Staub absaugen, was jedoch besondere `Hilfsvorriclttung@en erfordert, die überdies die Bearbeitung der Füllnasse erschweren würden. Nach der Erfindung ist dieser Übelstand unter Wahrung der genannten Erfordernisse dadurch vermieden, daß als Füllmasse eine an sich bekannte Legierung dient, die aus etwa 8 5 Teilen Cadmium und etwa 15 Teilen Zinn besteht. Diese Legierung hat infolge des Wegfalles -,7"on Blei bei der Bearbeitung mittels der Feile und der Bürste für die damit beschäftigten Arbeiter keine gesundheitsschädigende Wirkung mehr. Dabei ist diese Legierung während ihrer Erstarrungsdatier knetbar und besitzt die erforderliche Säurebeständigkeit und Festigkeit. Die Bearbeitung der Füllmasse kann ferner in der gleichen vorteilhaften Weise vorgenommen werden wie bei der bisher üblichen, das ges@undheits.schädliche Blei enthaltenden Legierung.So far, an alloy has been used as the filling compound, which consists of about 75%. Lead and about 250/0 tin. This alloy meets the requirements mentioned, but the surface of the filling line must now be processed with the file and the brush after it has been introduced into the recess. This creates a fine metal dust; which is harmful to the health of the workers employed because of its lead content. This dust could be sucked off, which, however, requires special auxiliary devices, which would also make processing the filling liquid more difficult. According to the invention, this deficiency is avoided while maintaining the requirements mentioned in that an alloy known per se is used as the filling compound, which consists of about 85 parts of cadmium and about 15 parts of tin. Due to the elimination of 7 "lead when working with a file and brush, this alloy no longer has any harmful effects on the health of the workers involved Filling compound can also be made in the same advantageous manner as with the previously customary alloy containing lead, which is harmful to health.
