Stand der Technik: Infolge einer starken Vergrößerung und einer fortlaufenden Steigerung des Industriepotentials nimmt zur Zeit proportional zu dieser Steigerung auch die Anzahl der Brände zu. Besonders leiden unter diesen Bränden die chemischen, sowie die Gas- und Erdöl verarbeitenden Industriezweige, wo Havarien leichtentflammbarer Flüssigkeiten, Brenngase u. dgl., die eine Explosionsgefahr darstellen, möglich sind, wie auch die Holz-und die Kohleindustrie. Darüber hinaus hat ein Pulver weltweit Anwendung als Feuerlöschmittel gefunden, das ein mechanisches Gemisch, zum Beispiel auf Basis von bis zu 95-97 Masseprozent Natriumhydrogencarbonat oder Ammoniumphosphatsalzen mit Aerosil® oder Graphit, darstellt (M. E. Krasnjanskij, '"Feuerlösch- und Explosionshemmende Pulver", 1990 "Donbass", Donezk, S. 16-25). Das genannte Pulver wird mit einem Gas, das unter Druck zugeführt wird, in die Brandzone befördert. Das unter Druck zerstäubte Pulver bildet ein Feststoff-Luft-Gemisch, das brennende Gegenstände umhüllt und das Feuer durch Ausschluss von Sauerstoff löscht. Jedoch besitzt das bekannte Pulver infolge seiner Neigung zum Zusammenballen und Klumpenbilden schlechte Betriebseigenschaften, wodurch seine Förderung aus dem Vorratsbehälter in die Brandzone behindert wird. Das bekannte Pulver ist hauptsächlich zur lokalen Brandlöschung verwendbar. In der Feuerlöschpraxis werden als Feuerlöschmittel seit langem Pulvergemische von verschiedenen Typen verwendet. Die meist verbreitet verwendeten Pulvergemische können auf Grund ihrer Wirkstoffe auf die folgende Weise gruppiert werden: State of the art: Due to a large increase and a continuous increase in industrial potential, the number of fires is increasing in proportion to this increase. Particularly suffer from these fires, the chemical, and the gas and oil processing industries, where accidents of highly flammable liquids, fuel gases u. Like., Which represent an explosion hazard are possible, as well as the wood and the coal industry. In addition, a powder has been used worldwide as a fire extinguishing agent which is a mechanical mixture, for example based on up to 95-97% by mass of sodium bicarbonate or ammonium phosphate salts with Aerosil® or graphite (ME Krasnjanskij, '"Fire-extinguishing and Explosion-Inhibiting Powders"). 1990 "Donbass", Donetsk, pp. 16-25). The said powder is conveyed into the fire zone with a gas which is supplied under pressure. The pressurized powder forms a solid-air mixture that envelops burning objects and extinguishes the fire by exclusion of oxygen. However, the known powder, due to its tendency to agglomerate and clumping, has poor operating characteristics, thereby hindering its delivery from the reservoir to the fire zone. The known powder is mainly used for local fire extinguishing. In fire fighting practice, powder extinguishers of various types have long been used as fire extinguishing agents. The most widely used powder mixtures can be grouped according to their active ingredients in the following way:
1. Alkalimetallhydrogenkarbonate, 1. alkali metal bicarbonates,
2. Alkalimetallhydrogenkarbonat-Addukte,  2. alkali metal bicarbonate adducts,
3. Alkalimetallhalogenide,  3. alkali metal halides,
4. Phosphatgemische,  4. phosphate mixtures,
5. Gemische von Alkalimetallsulfaten und -Boraten  5. Mixtures of alkali metal sulfates and borates
Von den obigen Gruppen sind die Stoffe der Gruppen 1 und 2 spezielle Wirkstoffe für Löschpulver für Flüssigkeitsbrände (Brandklasse B), die Stoffe der Gruppe 3 sind zum Löschen von Leichtmetall- und Metallbränden (Brandklasse D) geeignet und die Stoffe der Gruppen 4 und 5 sind Wirkstoffe von. Löschpulvern für glutbildende Brandobjekte (Brandklasse A) und für Flüssigkeitsbrände. Die Feuerlöschmittel, die auf Wirkstoffe der Gruppen 1 , 2, 4 und 5 basieren, sind auch zum Löschen von Gasbränden (Brandklasse C) geeignet. Of the above groups, the substances of groups 1 and 2 are special active substances for extinguishing powder for liquid fires (fire class B), the substances of group 3 are suitable for extinguishing light metal and metal fires (fire class D) and are the substances of groups 4 and 5 Active ingredients of. Extinguishing powders for glowing fire objects (fire class A) and for liquid fires. Fire extinguishing agents based on group 1, 2, 4 and 5 active substances are also suitable for extinguishing gas fires (fire class C).
Die Löschpulver können neben den Wirkstoffen auch Stoffe zur Sicherung der Hydrophobie und der Fließeigenschaften und gegebenenfalls auch andere Zuschläge enthalten. Heute enthalten die modernsten Trockenlöschpulver als Wirkstoff die Addukte der Gruppe 2. Solche Trockenlöschpulver sind z.B. in den folgenden Patentschriften beschrieben: GB-PS 1 118 215, GB-PS 1 168 092, GB-PS 1190 132 und DE 2 258 256. Die Löschwirkung dieser Pulver ist 3-5-mal so groß, wie die der klassischen Löschpulver, die Alkalimetallhydrogenkarbonate enthalten. Die Addukte sind stabil und inert. Ihre Nachteile sind die zum Löschen notwendige relativ kleine Korngröße, wodurch die Spritzweite begrenzt wird, sowie die hohen Herstellungskosten der Wirkstoffe. Der Löschmechanismus der Trockenlöschpulver ist folgendermaßen definiert. Die grundlegende Löscheigenschaft der Trockenlöschpulver ist das Inhibieren der Radikalkettenreaktion der Verbrennung. Das Inhibieren findet in heterogener oder in homogener Phase statt. Im ersten Fall funktioniert das Pulverteilchen, das in die Flammzone hineingelangt ist, als eine "elementare "Wand", während in der Reaktion, die in homogener Phase verläuft, das Alkalimetallteilchen von der Oberfläche des Pulvers verdampft und im Dampfzustand die den Verbrennungsvorgang weiterführenden Teilchen rekombiniert. Der Effekt der Inhibition hängt von der Natur der im Laufe der thermischen Zersetzung aus dem Pulver entstehenden Teilchen, der Teilchengröße, die mit den Ausschussparametern die Verweilzeit des Pulverteilchens in der Flammzone bestimmt,- sowie der Größe der Teilchenoberfläche ab, worin die Größe der Teilchenoberfläche die heterogene Rekombinierung, sowie durch die Menge der verdampften Zone die sekundäre, homogene Rekombinierung beeinflusst. Bei der Prüfung des Inhibitionsmechanismus ist festgestellt worden, dass es vorteilhaft ist, wenn im Falle des entsprechend ausgewählten Wirkstofftyps die Oberfläche des Pulverteilchens und die Verweilzeit des Teilchens in der Flammzone erhöht werden können. Neben dem grundlegenden Inhibitionsmechanismus der Flammlöschwirkung tritt auch die Sauerstoff- Verdrängungswirkung der bei der thermischen Zersetzung des Löschmittels entstehenden Inertgase als eine sekundäre Löschwirkung auf. Daher sind die Trockenlöschpulver meistens Stoffe, aus denen beim Löschen eine große Menge von Inertgasen (z. B. Kohlenstoffdioxid) freigesetzt wird. Auch freigesetztes Ammoniak unterbindet als Radikalfänger die chemische Reaktion des Verbrennungsvorgangs. In addition to the active substances, the extinguishing powders can also contain substances for securing the hydrophobicity and the flow properties and possibly also other additives. Today, the most modern dry-erase powders contain the adducts of group 2 as active ingredient. Such dry-erase powders are described, for example, in the following patents: GB-PS 1,118,215, GB-PS 1,168,092, GB-PS 1190,132 and DE 2,258,256. The extinguishing effect this powder is 3-5 times as large as that of the classic extinguishing powder containing alkali metal bicarbonates. The adducts are stable and inert. Their disadvantages are the necessary for deletion relatively small grain size, whereby the spray width is limited, and the high production costs of the active ingredients. The quenching mechanism of the dry-erase powders is defined as follows. The basic quenching property of the dry-erase powders is to inhibit the radical-chain reaction of combustion. The inhibition takes place in heterogeneous or in homogeneous phase. In the first case, the powder particle that has entered the flame zone functions as an "elemental" wall, whereas in the homogeneous phase reaction, the alkali metal particle evaporates from the surface of the powder and in the vapor state recombines the particles continuing the combustion process The effect of the inhibition depends on the nature of the particles resulting from the powder during the thermal decomposition, the particle size which determines with the reject parameters the residence time of the powder particle in the flame zone, and the size of the particle surface, in which the size of the particle surface heterogeneous recombination, as well as the amount of vaporized zone influences the secondary, homogeneous recombination can be increased according to the selected type of active substance, the surface of the powder and the residence time of the particle in the flame zone. In addition to the basic mechanism of inhibition of the flame-extinguishing effect, the oxygen displacement effect of the inert gases formed during the thermal decomposition of the extinguishing agent also occurs as a secondary extinguishing effect. Therefore, the dry-erase powders are mostly substances from which a large amount of inert gases (eg carbon dioxide) is released when extinguished. Liberated ammonia also prevents the chemical reaction of the combustion process as radical scavenger.
Weitere Bedingungen der Wirksamkeit eines Feuerlöschpulvers sind neben der guten Löschwirkung ein geeignetes Fließverhalten, eine gute Stabilität und eine große Hydrophobie. Es ist ein großes Problem gute Löschwirkung und eine geeignete Wurfweite gleichzeitig zu sichern, da vom Standpunkt der Löschwirkung die kleine und vom Standpunkt der Wurfweite die großen Korngrößen die vorteilhafte Größe sind. Mittels geeigneter Zuschlagstoffe können aber die Wurfweite der kleinen Teilchen erhöht, sowie das Fließverhalten verbessert werden. Other conditions of the effectiveness of a fire-extinguishing powder are in addition to the good extinguishing effect a suitable flow behavior, good stability and high hydrophobicity. It is a great problem at the same time to ensure good extinguishing effect and a suitable throwing distance, since from the point of view of the extinguishing effect the small and from the point of view of the throw the large grain sizes are the advantageous size. By means of suitable additives but the throw of small particles can be increased, and the flow behavior can be improved.
Nicht alle der bekannten Mischungen, die auf Wirkstoffe der Gruppen 1 , 2, 4 und 5 basieren, können in den Brandklassen der Kategorien A, B und C eingesetzt werden. Not all of the known blends based on Group 1, 2, 4 and 5 actives can be used in Class A, B and C fire classes.
Bekannt ist, dass für ABC Pulver ein Gemisch von >20 Gew% Ammoniumphosphat und von <80 Gew% Ammoniumsulfat und unterschiedlichen Zuschlagstoffen verwendet wird. Dabei gilt bisher, dass mit steigendem Phosphatanteil auch die Löschwirksamkeit zunimmt. It is known that a mixture of> 20% by weight of ammonium phosphate and <80% by weight of ammonium sulfate and various additives is used for ABC powder. It has hitherto been the case that with increasing phosphate content the extinguishing effectiveness also increases.
Aufgabe der vorliegenden Erfindung ist es gewesen, ein Feuerlöschpulver, insbesondere Trockenlöschpulver, bereit zu stellen mit einem geringeren Ammoniumphosphatanteil bei vergleichbaren guten Löscheigenschaften wie Pulverzusammensetzungen mit einem höheren Phosphatanteil als 20 Gew%. Zusätzlich soll das Feuerlöschpulver in den Brandklassen A, B und C gute Löscheigenschaften aufweisen. It is an object of the present invention to provide a fire-extinguishing powder, in particular dry extinguishing powder, having a lower ammonium phosphate content with comparable good extinguishing properties as powder compositions having a phosphate content greater than 20% by weight. In addition, the fire extinguishing powder in fire classes A, B and C should have good extinguishing properties.
Unter dem Begriff Feuerlöschmittel werden die Trockenlöschmittel verstanden die nicht mit Wasser konfektioniert werden, sondern ausschließlich als Trockenpulver zum Einsatz kommen. The term "fire-extinguishing agents" is understood to mean the dry-extinguishing agents which are not formulated with water but are used exclusively as dry powder.
Ein weiterer Gegenstand der vorliegenden Erfindung ist es gewesen, eine Zusammensetzung eines Feuerlöschpulver, insbesondere ein Trockenlöschpulver zur Verfügung zu stellen, die ökonomisch und ökologisch sinnvoll hergestellt wird und nach Gebrauch keine weiteren Entsorgungskosten generiert. Ebenfalls sollte das Produkt nach der Verwendung umweltverträglich sein und keine oder nur eine geringe Gesundheitsbeinträchtigung darstellen und eine hohe Lagerstabilität aufweisen. Another object of the present invention has been to provide a composition of a fire-extinguishing powder, in particular a dry extinguishing powder, which is produced economically and ecologically sensible and generates no further disposal costs after use. Also should the product after the use of environmentally friendly and no or only a slight health impairment and have a high storage stability.
