Definitions

  • the invention relates to an agent, in particular for fire fighting and impregnation, consisting of an aqueous solution which has one or more nonionic surfactants in a concentration of 0.02 to 0.2 percent by volume, and a method for the production thereof.
  • Fire fighting solutions of this type are known (DE-0S 31 00 158).
  • be used as a boundary-active agents are primarily those that are obtainable by condensation of ethylene oxide or propylene oxide with various substances and in particular with phenoll o ⁇ rule compounds having a side chain.
  • Combinations of one or more nonionic surface-active agents are selected in order to achieve water solubility within a 20-100 ° C. cloud point range in order to produce the smallest possible amount of foam.
  • the object of the invention is to create a finely sprayable mixture of substances with a high impregnation capacity which at the same time is readily biodegradable and non-toxic. This object is achieved in that alkylarylsulfonate is used as the surfactant.
  • alkylarylsulfonates (R-Ar-S0 3 -Me) were mainly known as raw materials for synthetic detergents. They have good evolving, degreasing and wetting properties as well as a high chemical resistance. Because of their generally unbranched compounds, they are readily biodegradable. Their toxicity to fish is based solely on the fact that they significantly lower the surface tension of the water.
  • the agent or substance mixture according to the invention can be used advantageously in particular for fire extinguishing or prevention, since the distribution of the individual drops of extinguishing agent at the spray nozzle of the extinguishing device becomes much finer due to the substantial reduction in the surface tension due to alkylarylsulfonate. At the same time, the surface of the extinguishing agent to be sprayed
  • a slightly acidic environment with a pH of 6.5 is built up.
  • 30% acetic acid (CH-C00H) in a concentration of 0.2 percent by volume is mixed with two percent by volume of distilled water to form a solution.
  • This buffer solution also reduces the risk of foam formation, which is unavoidable when tensides are added.
  • the proportion of alkylarylsulfonate in the extinguishing agent is limited to about 0.09 percent by volume. In practice, such
  • an aqueous solution with alkali metal citrate and / or sulfates up to the saturation concentration is used as the extinguishing agent.
  • This solution is colorless, clear, neutral smelling and viscous.
  • alkali metal citrate With alkali metal citrate, a prophylactic impregnation of the fire environment and / or a general impregnation of various, easily flammable materials can be achieved, which thereby become largely fire-resistant.
  • the impregnation effect is then further optimized by adding or combining with alkylarylsulfonate.
  • the use of the agent according to the invention in firefighting leads to a reduction in the extinguishing agent requirement, a widening of the spray mist and a densification of the spray curtain when it emerges from the spray nozzle of the extinguishing device, which enables it in particular to fight class A and B fires .
  • the agent according to the invention can in particular contain fires with a strong formation of embers.
  • alkali metal citrate in aqueous solution 91.4 percent by volume of alkali metal citrate in aqueous solution are used for the agent according to the invention. This is admixed with 1,2-thanediol to 2.1 percent by volume with distilled water to 4.2 percent by volume. As a buffer solution to create a slightly acidic environment with a pH of 6.5, 0.2% by volume of CrU-COOH (30%) is also added together with 2.0% by volume of distilled water. Finally, 0.09 percent by volume of alkylaryl sulfonate is added as a wetting agent.
