Definitions

  • the invention relates to a method for reducing odor or pollutant pollution in indoor spaces, in particular in indoor air, and to the use of the means required for this.
  • Prefabricated houses expresses in some cases extremely strong smells in the houses, which are often characterized as "moldy” or “musty”. Studies have shown that the cause lies in the microbial formation of chloranisols from the corresponding chlorinated phenols, which have been incorporated into the materials as wood preservative agents. The substances are characterized by an extremely low odor threshold and in the past were primarily responsible for the cork taste in wines and as contaminants for those treated with pentachlorophenol (PCP) Wooden pallets of transported food occurred. The human nose can already perceive a few pg (10 "12 g) 2,4,6-trichloroanisole.
  • PCP should not only be regarded as the starting substance. Since PSP has a fungicidal but not insecticidal effect, wood preservatives were added to PCP as well as ⁇ -hexachlorocyclohexane (lindane) up to PCP ban 1 989. In the new federal states, DDT was also used as an insecticide in many cases until 1 987. Lindane metabolites were also detected in the above studies. In addition, PCP was used in technical , quality and always contained quantitative amounts of tri- and tetrachlorinated phenols.
  • the object of the present invention is to provide a method with which the pollution and odors in the interior can at least be reduced.
  • this object is achieved in that odorant or pollutant-binding adsorbents are introduced into cavities which surround the interior
  • Treated wooden parts from which the problematic substances emit are found, for example, in prefabricated houses primarily in the compartment areas, more precisely in the cavities between the inner and outer walls.
  • the adsorbents which bind the mostly volatile, odorous and harmful substances
  • an effective mitigation measure is taken directly at the source of the odor nuisance or Pollutant emissions made. Since the odor-causing substances and pollutants predominantly outgas from the stud frame, the introduction of the adsorbents into cavities prevents the undesired substances from penetrating into the interior, thereby keeping the pollutants or odors away from the users of the interior.
  • the absorbents are characterized by a large surface so that the substances to be bound can adhere well; Furthermore, they are able to bind the harmful substances chemically or physically, this binding being preferably irreversible under normal building, physical and chemical conditions.
  • Standard building, physical and chemical conditions are to be understood as those conditions that occur during normal use of a building, in particular this is a normal temperature range in which people can stay in the building and a correspondingly low solvent concentration. This is worth mentioning because desorption of the initially accumulated pollutants or odorous substances can generally take place through an increase in temperature or through the use of solvents.
  • the absorbents are advantageously introduced into the cavities by blowing in under pressure or by introducing appropriately doped, porous insulating materials; the cavities can also be filled with the absorbents.
  • porous polymers or molecular sieves are used as absorbents.
  • Acidic silica or silica gel, in particular, are provided for binding basic substances.
  • B. are amines.
  • Acidic substances such as phenols
  • Ion exchangers are preferably used for binding polar substances, it also being possible to use a mixture of the abovementioned absorbents in order to bind a broad spectrum of odorous and harmful substances within the walls.
  • the above-mentioned adsorbents can be used in particular for binding pentachlorophenol or 2,3,4,6-T ⁇ trachloranisole.
  • adsorbents By introducing the adsorbents into cavities, in addition to the direct absorption of the volatile problem substances, an inconspicuous and permanent binding of these problem substances is achieved, whereby by introducing the adsorbents into compartmentalized areas of the walls, these are normally not visible to the users of the interior spaces.

Abstract

L'invention concerne un procédé pour réduire les mauvaises odeurs et la charge polluante dans des espaces intérieurs, notamment dans l'air d'un espace intérieur, selon lequel des substances adsorbantes liant les substances odorantes et polluantes sont introduites dans des cavités qui se trouvent dans les parois entourant l'espace intérieur concerné.
