Definitions

  • insects can be found in wood which can cause damage therein. This relates for example to the death- watch beetle, woodworm and the like.
  • insects cannot always be successfully controlled by chemical means. Insects, larvae and eggs can already be present in the wood from the tree stage which, because of a sometimes insufficient drying of the wood, can still be alive when the wood has already been incorporated into constructions. Damage by insects can be a great problem particularly in older and valuable buildings with wooden structural parts.
  • the invention has for its object to offer a method for controlling insects, using which the insects can be killed in a very simple and reliable manner and the danger of possible recurrence is virtually eliminated.
  • a further object of the invention is to provide a method for performing a preservative treatment of wood present in building structures wherein it is not necessary to temporarily remove the wood from the structure for the purpose of the treatment.
  • the invention has as its further object to offer a method which can in principle be performed without any chemical additives, whereby no environmental impact can occur.
  • the invention generally provides a method for controlling insects present in wood, comprising the following steps of: (1) heating the wood until it has reached a minimum temperature of 45°C throughout; and (2) simultaneously preventing water present in the wood from leaving the wood.
  • Preventing water leaving the wood during heating can be of essential importance for two reasons.
  • a fall in the heat conduction due to a decreased relative humidity must be prevented.
  • a highly effective heat penetration can thereby be realized with relatively low energy consumption.
  • the heat up time hereby remains limited.
  • stretch and shrinkage do not occur in the wood due to drying out, which could cause damage to and weakening of the structure owing to local strains.
  • the choice of a minimum attainable temperature of 45*C is based on the insight that not only the insects and larvae but also eggs present in the wood are certainly killed at this temperature.
  • the method according to the invention can advan ⁇ tageously be characterized by
  • step (2) by placing the wood during performing of step (1) in an environment with a relative humidity of minimally 30%.
  • the method can be characterized by (4) performing step (3) by holding the relative humidity substantially constant at a pre-selected value.
  • a heating device with a hydrostatic regulator added thereto which maintains the amount of moisture in the relevant environment at the selected value.
  • the method is characterized by (5) performing step (1) by placing the wood in an environment with a temperature above the minimum temperature to be reached of 45 ⁇ C. Since Sprinkler installations are often present in buildings, care should be taken that the ambient temperature does not rise so high that the Sprinkler installation is set into operation. The ambient temperature created should therefore be limited to a temperature which lies for example several degrees below the activating temperature of the Sprinkler installation.
  • the method can for example be characterized by
  • step (5) performing step (5) with an ambient temperature in the order of magnitude of 15"C above the temperature to be reached.
  • step (1) adding chemical agents, in particular an insecticide such as S0 2 , ZnCl 2 and/or fungicide to the outside of the wood during step (1) , after a temperature in the order of magnitude of 35 ⁇ C has been reached.
  • This step is based on the insight that when the temperature rises to about 35 ⁇ C the insects will begin to display increased activity, whereby a number of insects may reach the outside of the wood. According to this step they there come into contact with the chemical pesticides.
  • a fungicide can control fungi, which may be necessary since the growth of these fungi is encouraged by the raised absolute humidity during the process according to the invention.
  • a method for treating wood present in an enclosed space can be advantageously characterized by 4
  • a chemical pesticide can advantageously be applied there.
  • a chemical pesticide can be added to the air when it is blown in.
  • the cracks serve for ventilation of the enclosed space whereby the build up of pressure therein remains limited.
  • the pesticides can be deposited there and, insofar as necessary, form a blockade against harmful insects later coming from outside. It is noted that larger cracks are preferably sealed prior to the control according to the invention.
  • the method can preferably be characterized by
  • the effective space is hereby reduced which is conducive to a small heat supply and rapid heating of the wooden construction parts. Often adjoining such a space is at least one space which does not have to be treated, or where the rise in temperature to be obtained by the invention must not be reached, for example in the case where valuable, vulnerable objects are present in this space.
  • the invention provides therefor a method for treating wood present in a first space which is in communication with a second space, which method is characterized by
  • the method can be performed according to the invention without a separate conditioned space, for example a kiln, being required therefor.
  • the invention thereby provides a particularly simple and reliable method for performing a preservative treatment of wood incorporated in building structures, wherein insects present in that wood are controlled according to one or more of the above described methods.

Abstract

Procédé permettant d'éliminer des insectes présents dans le bois, comprenant les étapes suivantes: chauffage du bois jusqu'à une température homogène minimum de 45 °C; maintien simultané de l'eau présente dans le bois par introduction de celui-ci dans un milieu possédant une humidité relative minimum de 30 %. Pour traiter le bois présent dans un espace fermé, le procédé comprend les étapes suivantes: soufflage d'air chauffé et humidifié dans ledit espace et réduction de la quantité d'air effective dans ledit espace par gonflement à l'intérieur de celui-ci d'au moins un ballon.
