Definitions
- the invention relates to a fire extinguishing agent.
- Typical fire extinguishing agents are water or organic foams.
- the fire extinguishing agent proposed in DE-AS 1 211 946 contains CO 2 -releasing salts in conjunction with organic acids and vermiculite which has been delivered or rolled out and then grained as a mica component.
- a dry chemical mixture as fire extinguishing foam is known from DE-PS 570 456.
- the mixture consists of aluminum sulfate, sodium bicarbonate and ssponin, to which, according to page 1, lines 50 to 55, a kaolin addition of 8 to 35% can also be added, which, however, suppresses the foam yield.
- the well-known dry chemical mixture has not become established because fire extinguishing foams cannot be made available in large quantities, for example for fighting forest fires.
- the fire extinguishing agent known from DE-PS 608 037 consists of extinguishing liquid loaded, economical, anerganic, porous, active measurements, the extinguishing liquid being carbon tetrachloride.
- the use of carbon tetrachloride is already ruled out from an environmental point of view for practical feasibility.
- a fire-suffocating effect should also be achieved with the fire extinguishing agent according to DE-PS 746 963 (page 1, lines 21 to 25), for which purpose the agent consists of a mixture of sand and an alkaline earth carbonate.
- the present invention is based on the object of offering a fire extinguishing agent which can also be used or is suitable in large quantities, in particular for fighting large-scale fires, and which is easy to handle and above all should not have any components which are harmful to the environment: on the contrary, it is strived to provide a fire extinguishing agent that not only shows an optimal fire extinguishing effect, but is also as environmentally compatible as possible after performing this function and does not require separate disposal, as is the case with chemical-based fire extinguishing agents.
- the invention is based on the knowledge that the disadvantages known from the prior art can be overcome if, instead of a single, a targeted combination of different clay minerals is used as an adsorbent for other constituents of the clay mineral, such as kaolimt, which complement each other in a synergistic way with regard to their individual properties and effects.
- a kaolinite as mentioned in DE-PS 570 456, leads to a very strong coagulation of the fire extinguishing agent, or a bentonite, as mentioned in DE-AS 1 130 294, leads to an undesirable strong thixotropy of the dry powder coming into contact with liquid
- surprisingly excellent stable suspensions can be achieved from a clay mineral mixture containing smbktite, kaolinite and clay minerals from the mica group as soon as the material comes into contact with the extinguishing liquid (usually water) or is mixed.
- the agent according to the invention can be used on an industrial scale.
- Such a clay mineral mixture is capable of absorbing considerable amounts of water, the preferred water / solids ratio being between 10: 1 and 3: 1, and even with these large amounts of water there are outstandingly stable suspensions.
- the compulsory constituents smectite, kaolimt and mica, in particular illite, are preferably mixed together in the proportions specified in claim 2. Depending on the proportion of the individual clay minerals, the mixture can then absorb a non-flammable extinguishing liquid, in particular water, in the amount specified in claim 7.
- the smock according to the invention also offers a decisive advantage over known fire extinguishing agents in that its ability to bind water can be maintained over a considerably longer period than previously known. This means that the fire extinguishing agent is available for firefighting or fire prevention for a longer period of time, but it can also reliably prevent the fire from starting again because the solid particles can absorb water again at a later time. The remedy then turns out to be quasi reversible
- the fire extinguishing agent according to the invention is particularly easy to handle.
- the density increases from 1.0 g / cm 3 to 1.05 to 1.5 g / cm 3 or above. This increases the falling speed, for example when the extinguishing agent is dropped from an aircraft, and the risk is reduced that the extinguishing agent is carried away by the wind without having its extinguishing effect at the source of the fire.
- Clay mineral particles are also ensured that, for example, evaporation losses due to the heat of the fire are considerably minimized.
- the spontaneous readiness of the clay mineral mixture to absorb extinguishing liquid also creates the possibility of first discharging the material dry and only later performing the actual extinguishing by spraying extinguishing water, which in turn results in a longer effectiveness due to the high water binding capacity of the clay mineral particles.
- the clay / mineral mixture according to the invention can also have natural or added fractions of quartz, opaque and / or feldspar as well as accessory batch fractions.
- the accessory batch proportions include substances such as magnetite that bind oxygen, especially at higher temperatures at around 1000 ° C.
- the agent also leads to a reduction in toxic flue gas and soil components through adsorption, absorption and / or catalytic Implementation.
- Additions of calcium carbonate or magnesium carbonate in particular, for example in the form of lime or dolomite, further increase the fire-suffocating effect of the agents, in particular by releasing CO 2 in the fire or forming Ca (OH) 2 and / or Mg (OH) 2 Contact with water.
- the fire extinguishing agent according to the invention has its effect not only with regard to the actual fire fighting, but also in the disposal of toxic components in the air and in the ground.
- the fire extinguishing agent itself is fire-resistant up to approx. 1200 ° C and higher, which means that it can withstand the highest forest fire temperatures and is preferably sprayed or thrown onto the surfaces to be extinguished as a suspension in finely dispersed form. Even if the water evaporates after a certain time, the clay mineral constituents still adhere to the extinguished forest areas (trees) or components and form a kind of "protective layer", as a result of which they remove the "food" from the fire as well as when used in the form of dry powder.
- the agent Due to the exclusively natural, mineral components, the agent is completely harmless to humans, animals or plants. As explained above, it can then even be used to meliorate damaged soils, for example if it is washed off by subsequent rain.
- Additions such as sodium carbonate or water glass can have a further positive influence on the water retention capacity.
- a number of further substances are available to the person skilled in the art which have a dispersing effect and / or which promote water retention.
- the liquefying cationic or aniomic agents such as sodium silicate or surface active surfactants.
- the accessory quantity components also include those such as magnetite (Fe 3 O 4 ), which is able to bind oxygen, especially at higher temperatures, such as those prevailing in forest fires. It is evident that such oxygen scavenging makes a further contribution to containing a conflagration.
- magnetite Fe 3 O 4
- the agent could be adjusted in such a way that the addition of salt-containing sea water and extinguishing liquid to a clay mineral mixture according to the invention also has a catalytic effect on its activation with respect to the water retention capacity or dispersion of the components.
- the fire extinguishing agent according to the invention can of course also be applied by means of conventional fire trucks or corresponding devices.
- the high stability of the suspension ensures that the material does not sediment even with long transport routes or rest periods and therefore still develops its full effectiveness.
