Description

Acetylenreinigungsmittel in Stückenform. Wie in Wissenschaft und Technik bekannt und anerkannt, sind die Chromsäure und chromsäurehaltige Mischungen dasjenige Reinigungsmittel für Acetylen, welches das Acetylen am sichersten, vollkommensten und schnellsten von allen seinen Verunreinigungen zu befreien vermag. Solche chromsäurehaltigen Reinigungsmittel kannte man bisher aber nur in Pulverform, als sogenanntes »Heratol«. Dieses ist für Hordenreiniger gut brauchbar, eignet sich aber nicht für Reiniger ohne Horden, weil bei solchen das pulverförmige Reinigungsmittel dem Acetylengas den Durchtritt verwehren und zu Verschlammungen führen würde. Für solche Reiniger ohne Horden ist daher die Anwendung der Reinigungsmasse in Stückenform notwendige Bedingung.Acetylene detergent in lump form. As in science and technology known and recognized, the chromic acid and chromic acid-containing mixtures are the one Detergent for acetylene, which acetylene is safest, most perfect and able to get rid of all its impurities as quickly as possible. Such chromic acid-containing So far, cleaning agents have only been known in powder form, known as "Heratol". This can be used for tray cleaners, but is not suitable for cleaners without hordes, because with such the powder detergent is the acetylene gas would prevent the passage and lead to silting. For such cleaners Without a rack, it is therefore necessary to use the cleaning compound in lump form Condition.

Man kennt zwar auch schon Reinigungsmassen in Stückenform, wie insbesondere solche aus Chlorkalk. Aber einerseits haben diese Reinigungsmittel nicht eine so guteWirkung wie die Chromsäure, anderseits zeigen sieden Nachteil, an der Luft und bei Feuchtigkeitszutritt zu zerfallen.One already knows cleaning compounds in lump form, such as in particular those made from chlorinated lime. But on the one hand, these detergents don't have one like that good effect like chromic acid, on the other hand they show the disadvantage, in air and to disintegrate when exposed to moisture.

Versuche, die ,chromsäurehaltige Reinigungsmasse in Stückenform zu bringen, sind bisher gescheitert, weil- die gebräuchlichen porösen Stoffe, wie z. B. Bimsstein o. dgl., zu geringe Saugfähigkeit besitzen, daher zu wenig von dem Chromsäurehaltigen Reinigungsmittel in sich aufnehmen. Auch wird unter dem Einfluß der starken Säuren die Festigkeit des Bimssteines verringert. Es hat sich nun gezeigt, daß man ein vorzügliches chromsäurehaltiges Acetylenreinigungsmittel in Stückenform erhält, wenn man zur Aufsaugung die durch Sinterung von Kieselgur erhaltene hochporöse Steinmasse benutzt, die unter der Bezeichnung »Diatomit« bekannt ist und bisher im wesentliches. als Wärmeschutzmaterial benutzt wird. Die gesinterte Kies.elgur hat eine konstante Saugfähigkeit, die mehr als sechsmal so groß ist als die des porösesten Bimssteins, gibt die aufgesaugte Flüssigkeit nicht ab und wird durch Säuren nicht angegriffen.Try to use the chromic acid-containing cleaning compound in pieces bring, have failed so far because the common porous substances such. B. pumice o. The like. Too low absorbency, therefore too little of that Take up cleaning agent containing chromic acid. Also being under the influence strong acids reduce the strength of the pumice stone. It has now been shown that you have an excellent chromic acid-containing acetylene cleaning agent in lump form obtained when the highly porous obtained by sintering kieselguhr for absorption Stone mass used, which is known under the name "Diatomite" and until now essentially. is used as a heat protection material. The sintered diatomaceous earth has a constant absorbency that is more than six times that of the porous pumice stone, does not release the absorbed liquid and gets through Acids not attacked.

Läßt man die aus Bichromaten und Schwefelsäure erhaltene Reinigungsflüssigkeit von unregelmäßigen Stücken der gesinterten IGeseigurmasse aufsaugen, so erhält man ohne weiteres eine stückenförmige Acetylenreinigungsmasse für Reiniger ohne Horden, welche die chromsäurehaltige Reinigungsflüssigkeit gut festhält, ohne zu zerbröckeln, und die Reinigung des Acetylens in gleich guter Weise zu bewirken vermag, wie dies die bekannten Reinigungsmittel in Pulverform bei Hordenreinigern tun.Leaving the cleaning liquid obtained from bichromates and sulfuric acid soak up irregular pieces of the sintered IGeseigurmasse, so one obtains easily a piece of acetylene cleaning compound for cleaners without hordes, which holds the chromic acid containing cleaning fluid firmly without crumbling, and capable of purifying the acetylene in as good a manner as this the well-known detergents in powder form for rack cleaners do.
