Definitions

  • the invention relates to a method for combating and killing fungi and / or sponges on organic materials and building materials, in particular in the case of watering, with the aid of dehumidified, compressed and heated air.
  • Organic materials have been a building material that has been used for centuries.
  • wood is used for cladding walls and ceilings in living rooms, as load-bearing elements in wooden beam ceilings, as flooring and the like in the construction industry. It is therefore of particular importance when installing such a material in buildings to ensure that it is in perfect condition, to ensure proper and good dehydration and in older sponge-infested areas Houses effectively and effectively carry out the measures necessary to remove the sponge or fungus infestation in order to eliminate all germs so that recurring damage is avoided at all costs.
  • the fight against sponge infestation can be carried out without or with the help of surgical interventions, the first attempt being made to combat without surgical interventions, i.e. by gasification, for example with carbonic acid or by heat or heat.
  • gasification for example with carbonic acid or by heat or heat.
  • the far more elaborate operational method assumes that the cause of moisture is determined, then the oven dries out and then, after the infected construction parts have been exposed, the careful and conscientious renovation work can begin.
  • the present invention consists in proposing a method which not only serves to dehumidify building structures, but also in which there is a sustainable elimination of any germination possibilities (mold infestation and spread).
  • the inventive measure is based on the knowledge that the temperatures have to be selected with an effective control of the sponge in such a way that future germination and growth in the future are also prevented.
  • the mycelium (mushroom network) of each mushroom type also has a certain constant length growth value for a constant growth temperature.
  • the increase in length begins with the wood-destroying fungal mycelia at approx. 3 ° C and from then on increases with the temperature up to the optimal growth point.
  • a similar substrate e.g. a plank undersurface
  • a plank undersurface e.g. the mycelium of the real house sponge (merulius domesticus lacrimans) from a growth spot evenly in all directions.
  • the most favorable growth temperature for house sponge types is between 18 and 26 ° C, with a favorable moisture content of the wood of 20% to about 40%.
  • the growth rates in 10 days for real house sponges at 22 ° C are about 6 cm, at 5 ° C only 1.3 cm. This means that the real house sponge shows measurable growth even at relatively low temperatures.
  • the other types of sponge also show a growth of 5.5 to approx. 7 cm within 10 days in the temperature range up to 30 ° C
  • condensation water condensation water
  • condensation water condensation water
  • FIG. 1 shows the construction of a beam ceiling
  • FIG. 2 shows the drying of a beam ceiling
  • FIG. 3 finally shows the drying of a screed insulation.
  • Fungicidal gases such as formaldehyde can also be used in connection with the process according to the invention.
  • the fungicide acts on the lively breathing fungi of a sponge and leads to the killing of the fungus growth within the gas phase.
  • the amount of liquid depends, for example, on the size of the air space under the planks to be gasified, ie about 120 cm 3 of formaldehyde is required for one cubic meter of space to be gasified.
