Description

Spreugkapsel. Die zur Herstellung von Sprengkapseln verwendeten Metallhülsen aus Kupfer, Messing, Zink, Aluminium, Eisen usw. verändern, besonders bei Gegenwart von Feuchtigkeit, das Knallquecksilber des Knallsatzes, indem sich metallisches Quecksilber ausscheidet und Fulminate der betreffen-den zu den Hülsen verwendeten Metalle entstehen. Diese Fulminate sind unbeständig, zersetzen sich schon in kurzer Zeit und die Sprengkapseln, wer-den dadurch unwirksam und als Initialzünder unbrauchbar. Man hat diesen Nachteil dadurch zu beseitigen gesucht, daß man z. B. die aus Messing oder Eisen hergestellten Hülsen verkupfert hat, weil das Kupfer weniger stark zersetzend auf das Knallquecksilber einwirkt als Zink bzw. Messinge Auch ein Verzinnen der aus Kupfer hergestellten Hülsen wird vielfach ausdenselben Gründen ausgeführt.. Aber auch verzinnte Kupferhülsen wirken noch merklich auf Knallquecksilber ein, so daß sich z. B. metallisches Quecksilber im Messing der Geschoßzünder nachweisen läßt, wenn derartige Zünder mit einer verzinnten Knallquecksilberkapsel geladen werden und in diesem geladenen Zustand längere Zeit, etwa zwei Jahre, lagern. Viel widerstandsfähiger gegen Knallquecksilber als die Hülsen aus den vorerwähnten Metallen sind Hülsen aus Metallen der Eisengruppe. Auch das chemisch reine, vor allen Dingen kohlenstoffreine Eisen zeigt bei längerer Berührung eine kaum nachweisliche Einwirkung auf das Knallquecksilber. Noch besser verhalten sich Mangan, Nickel und Kobalt.Spreader capsule. The metal sleeves used to make detonators from copper, brass, zinc, aluminum, iron etc. change, especially in the present of moisture, the pop mercury of the pop set by becoming metallic Mercury is excreted and the fulminates used in the pods are concerned Metals are created. These fulminates are unstable and quickly decompose Time and the detonators become ineffective and useless as an initiator. One has sought to eliminate this disadvantage by z. B. those made of brass or iron-made sleeves copper-plated because the copper is less corrosive The fiery mercury acts as zinc or brass. Also tin-plating of the Sleeves made from copper are often used for the same reasons. But tinned copper sleeves still have a noticeable effect on fumed mercury, so that z. B. detect metallic mercury in the brass of the projectile fuse lets when such detonators are loaded with a tinned mercury capsule and store in this charged state for a long time, about two years. Much more resistant to fatal mercury than the sleeves made of the aforementioned metals are sleeves made of metals of the iron group. Also the chemically pure, above all Carbon-free iron shows hardly any detectable effect on prolonged contact on the mercury. Manganese, nickel and cobalt behave even better.

Die Hülsen aus diesen Metallen sind nicht nur teuer, sondern auch schwer zu ziehen. Es genügt zur Erreichung des genannten Zweckes schon, wenn Hülsen aus weichen, leicht ziehbaren Metallen, wie Kupfer, Messing, Zink usw., mit einer dünnen Plattierung oder einer elektrolytischen Schicht von Metallen der Eisengruppe versehen werden. Derartige Kapseln können nach dem Laden mit dem Knallsatz auch feucht werden, ohne daß eine Zersetzung des Knallquecksilbers eintritt.The sleeves made from these metals are not only expensive but also difficult to pull. It is sufficient to achieve the stated purpose if sleeves made of soft, easily drawn metals such as copper, brass, zinc, etc., with a thin plating or an electrolytic layer of metals of the iron group be provided. Such capsules can also be used after loading with the pop set become damp without decomposition of the fumed mercury occurs.
