Description
Streufähiges, Natriumchlorid enthaltendes Auftaumittel zur Beseitigung von Glatteis und Schneeglätte auf Straßen 13s ist bereits ein lagerfähiges Streupulver für das Auftauen von Glatteis und Schneeglätte vorgeschlagen worden, welches aus einem Gemisch von. Calciumchlorid und Natriumchlorid besteht, wobei auf r Gewichtsteil des erstgenannten mindestens etwa r Gewichtsteil des zweitgenannten kommen soll. 1?ine solche Mischung bleibt nicht nur, wenn. trocken gelagert, sehr gut streufähig, es werten vielmehr auch die insbesondere bei hohen Kältegraden schlechten Auftaueigenschaften cl es \#itriuinclilorids durch die 1-ivdratationswärme des Calciumchlorids wesentlich verbessert.Spreadable de-icing agent containing sodium chloride for disposal of black ice and slippery snow on roads 13s is already a storable scattering powder for the thawing of black ice and snowy snow has been proposed, which consists of a mixture of. Calcium chloride and sodium chloride consists, being on r part by weight of the former should come at least about r part by weight of the latter. 1? Ine such a mixture does not just remain, though. stored dry, very easy to spread, rather, the poor thawing properties, especially at high degrees of cold, are also valued cl es \ #itriuinclilorids due to the intravenous heat of calcium chloride improved.
Wie nun weiter gefunden wurde, läßt sich die gleiche Wirkung auch dadurch erreichen. daß man dem \ atriumchlorid andere Salze, z. B. Magnesiumchlorid, zumischt, welche bei der Berührung mit Eis infolge Hydratation Wärme entwickeln. Für diesen "!.weck läßt sich das wasserfreie Mal-nesiumchlorid ebenso wie seine Hvdrate verwenden. Auch hier verwendet man die beiden Salze zweckmäßig; irn Verhältnis t : i. hei Zurnischung von kristallwasserhaltigem Magnesiumchlorid kann mit der Menge auf die Hälfte bis ein Drittel heraligegangen «-erden. Cberraschenderweise behalten die in feingemahlenem "Zustand vorliegenden Gemische ihre Streufähigkeit selbst bei längerer Lagerung. Während Chlormagnesium bei Lagerung in luftverschlossenen Trommeln nach längerer Zeit durch Zusammenbacken nicht mehr streufähig bleibt, bleibt die Mischung unverändert; andererseits wird die Auftauwirkung wesentlich erhöht.As has now been found further, the same effect can also be found thereby achieve. that the \ atrium chloride other salts, z. B. magnesium chloride, mixed in, which develop heat when they come into contact with ice as a result of hydration. The anhydrous malnesium chloride can be used for this purpose just like his Use hvdrate. Here, too, the two salts are expediently used; in relation t: i. hot admixture of crystalline water Magnesium chloride can be approached by half to a third with the amount. Surprisingly the finely ground mixtures retain their throwing power even with long-term storage. While magnesium chloride when stored in airtight Drums no longer spreadable after a long period of time due to caking, remains the mix unchanged; on the other hand, the thawing effect is significantly increased.
Es ist zwar schon bekannt, daß das Zusammenbacken von gemahlenem Steinsalz durch einen Zusatz von llagnesiumchlorid weitgehend verhindert werden kann. Diesem Vorschlag ist jedoch weder eine Angabe über die im Gemisch auftretenden Mengenverhältnisse der beiden Salze noch ein Hinweis dahingehend zu entnehmen, daß ein solches Gemisch in dem Mischungsverhältnis gemäß Erfindung als Auftaumittel für Glatteis und Schneeglätte Verwendung finden kann.It is already known that the caking of ground rock salt can be largely prevented by adding magnesium chloride. This one However, the suggestion is neither an indication of the proportions occurring in the mixture of the two salts a hint to the effect that such a mixture in the mixing ratio according to the invention as a de-icing agent for black ice and snow Can be used.
Es ist ferner ein Streumittel zur Verhinderung des Ausgleitens bei Glatteis bekannt, das dadurch erhalten wird, daß stark saugfähige Stoffe, wie Holzspäne, Sägemehl, Torf u. dgl., mit Schnee- und eislösenden Salzen bzw. einer diese Salze enthaltenden Lösung vor dem Ausstreuen durchtränkt werden. Dieses Streumittel ist mit demjenigen ä ß der Erfindun- nicht in :"ergleich zu ziehen. da das letztere ledi-Iich für das Auftauen von Glatteis und Schneeglätte vorgesehen ist. Es unterscheidet ;ich außerdem von dein Bekannten dadurch, daß es keines der vorstehend genannten saugfähigen Bremsmittel enthält.It is also a scattering agent to prevent slipping Black ice known, which is obtained by the fact that highly absorbent substances, such as wood shavings, Sawdust, peat and the like, with snow and ice dissolving salts or one of these salts containing solution are soaked before scattering. This grit is with that ß of the invention not in: "to draw the same. as the latter it is only intended for thawing black ice and snow. It makes a difference ; I also tell your acquaintance that none of the above Contains absorbent braking agents.
