Description
Verfahren zur gefahrlosen Abtötung von Schädlingen und Keimen aller Art Durch Patent 5i4 775 ist unter Schutz gestellt ein Schädlingsbekämpfungsmittel, bestehend aus einem Gemisch aus Alky lenoxy d und Kohlensäure, «-elches nach Maßgabe der Beschreibung mit einem großen L?berschuß von Kohlensäure verwendet wird, um damit der durch die leichte Brennbarkeit der Alkylenoxyde bedingten Gefahr begegnen zu können.Process for the safe killing of pests and germs of all kinds. Patent 5i4 775 protects a pesticide consisting of a mixture of alkylene oxide and carbonic acid, which is used with a large excess of carbonic acid in accordance with the description, in order to be able to counter the danger caused by the easy flammability of the alkylene oxides.
Diese Arbeitsweise erfordert zur Erhaltung der für die Schädlingsvernichtung nötigen Konzentration an Alky lenoxy d, z. B. Äthylenoxy d, einen erheblichen Aufwand an Kohlensäure, die nicht nur an sich kostspielig ist, sondern infolge der erforderlichen Mengen bei der Aufbewahrung oder beim Transport viel Raum beansprucht und z. B. bei Aufbewahrung des Gemisches in druckfesten Flaschen einen großen Vorrat an solchen Flaschen voraussetzt.This way of working requires the maintenance of the pest extermination necessary concentration of Alky lenoxy d, z. B. Äthylenoxy d, a considerable effort of carbonic acid, which is not only expensive in itself, but as a result of the necessary Quantities in storage or transport take up a lot of space and z. B. if the mixture is stored in pressure-resistant bottles, have a large supply of such Assumes bottles.
Es wurde nun gefunden, daß man die durch jenes Vorgehen bedingten Nachteile. wie Verminderung der Konzentration des Schädlingsbekämpfungsmittels an wirksamem Stoff bzw. geringe Wirtschaftlichkeit infolge hohen Aufwandes an Kohlensäure und schwieriges Umfüllen, vermeiden kann, wenn man für eine sehr schnelle Vermischung des dem Aufbewahrungsbehälter entströmenden Gemisches mit Luft Sorge trägt und damit die Konzentration des Gemisches an brennbaren Stoffen unter die Brennbarkeits- bzw. Explosionsgrenze drückt.It has now been found that the conditions caused by that procedure were found Disadvantage. such as reducing the concentration of the pesticide effective substance or low economy due to high consumption of carbonic acid and difficult decanting, can be avoided if one is looking for a very quick mix of the mixture with air flowing out of the storage container and thus the concentration of the mixture of combustible substances below the combustibility or Explosion limit presses.
In Ausführung dieser Vorschrift kann man etwa derart verfahren, daß man das Gemisch durch einen Ventilator, eine Spritzpistole oder durch ein Treibmittel aus einer druckfesten Flasche in den zu begasenden Raum hineintreibt. Das bisher z. B. für ÄthYlenoxvdund Kohlensäure vorgesehene Mischungsverhältnis von nicht wesentlich unterhalb i : io kann dabei wesentlich zugunsten von Äthylenoxyd verschoben werden. Es genügt, die Menge der Kohlensäure so zu wählen, daß die Treibkraft ausreicht, eine möglichst schnelle Mischung des zu vergasenden Stoffes mit der Luft zu erzielen. Hierbei können Düsen bekannter Bauart, die das Ansaugen der Luft begünstigen, die schnelle Vermischung wesentlich fördern.In carrying out this rule one can proceed in such a way that the mixture by means of a fan, a spray gun or a propellant from a pressure-tight bottle into the room to be fumigated. That so far z. B. for ÄthYlenoxvdund carbonic acid provided mixing ratio of not essential below i: io can be shifted significantly in favor of ethylene oxide. It is sufficient to choose the amount of carbon dioxide so that the driving force is sufficient to achieve the fastest possible mixture of the substance to be gasified with the air. Here, nozzles of known design, which favor the suction of air, can be used promote rapid mixing significantly.
Eingehende Versuche haben gezeigt, daß durch die öben beschriebene Maßnahme nicht nur eine schnelle Verteilung erreicht wird, sondern das Gemisch auch in seiner hoch toxischen Form erhalten und durch das schnelle Heranbringen Schädlingen jede Möglichkeit genommen wird, etwa Abwehr- oder Schutzstellungen einzunehmen. Damit wird also nicht nur die Handhabung jener Gemische erleichtert, sondern insbesondere auch eine unbedingt sichere Wirkunggewährleistet. indem das Gemisch eine vervollkommnete Ausnutzung erfährt.In-depth tests have shown that the above described Measure not only a rapid distribution is achieved, but also the mixture preserved in its highly toxic form and pests by the rapid introduction every opportunity is taken to take defensive or protective positions, for example. So that will not only facilitates the handling of those mixtures, but in particular also guarantees an absolutely safe effect. by that Mixture experiences a perfect utilization.
