Description

Verfahren zur Erhaltung des pulverförmigen Zustandes von calcinierter Soda beim Lagern. Da wasserfreie pulverförmige Soda leicht dazu neigt, in kurzer "Zeit steinhart zu «-erden, so wendet man vorzugsweise Ainmoniaksoda in Form von Kristallsoda an. Diese hat den -Nachteil, daß sie etwa 6o Prozent Wasser enthält und sich dadurch bei der Ver frachtung wesentlich teurer stellt als Soda in Pulverform.Process for maintaining the powdery state of calcined Soda when storing. Since anhydrous powdered soda easily tends to be in short "Time to earth rock hard", so one preferably uses Ainmoniaksoda in the form of Crystal soda. This has the disadvantage that it contains about 60 percent water and is therefore significantly more expensive to transport than soda in powder form.

Gegenstand der Erfindung ist ein Verfahren, um calcinierte Soda beim Lagern pulverförmig zu halten. Zu dem Zweck -,verdee der Soda geringe Mengen von fein gepulvertein Bora:, und zwar ungefähr 5 Prozent, zugesetzt. Hierdurch wird erreicht, daß der pulverförmige Zustand der Ammoniaksorla beim Lagern erhalten und ein Hartwerden derselben verhütet wird. Der "Zusatz bewirkt außerdem gleichzeitig die Erhöhung der Waschkraft des Sodapulvers. Sodageinische mit Chlorkalle und Borax sind bekannt. Das beanspruchte Verfahren verwendet demgegenüber nur geringe Mengen von Borax ohne weitere Zusätze.The invention relates to a method for calcined soda Keep storage powdery. For the purpose -, verdee small amounts of soda finely powdered in Bora: approximately 5 percent added. This will achieved that the powdery state of Ammoniaksorla obtained during storage and hardening of the same is prevented. The "addition also effects at the same time increasing the washing power of soda powder. Soda teak with chlorinated ball and borax are known. In contrast, the claimed method uses only small amounts of borax without further additives.
