Definitions

  • the invention is therefore based on the object of providing a simple method for impregnating wood which can be carried out with low process risks, and of presenting a wood with improved mechanical properties.
  • thermowood is more brittle than before the heat treatment. There was no significant improvement in weather resistance.
  • the waxes that are used to impregnate the thermowood are preferably solid at room temperature. Their melting point is well above room temperature.
  • thermowood which has been treated with the method according to the invention is immediately ready for use. It no longer has to be subjected to complex and complicated drying processes. The risk of producing rejects is eliminated or is significantly reduced.
  • thermowood At least in the unpressurized treatment of thermowood, the cooling contraction presumably results in microscopic pores which have the desired moisture absorption of e.g. B. allow condensation without causing swelling of the thermowood.
  • the wax is continuously circulated during the 45 minutes by connecting the supply and discharge lines and switching on a pump. After the 45 minutes have passed, the supply and discharge lines are decoupled and the liquid wax is pumped out of the pressure chamber. Pressure equalization is initiated and the chamber is opened after the equalizing pressure is reached.
  • the thermowood is examined after cooling. The treatment absorbed 25% by weight of wax based on dry wood. After cooling, the compressive strength is approx. 7% higher than the compressive strength of the untreated wood. When planing the wax-impregnated wood, the surface is smoother than when planing untreated thermowood.

Abstract

L'invention concerne un procédé pour introduire de la cire dans du bois thermique, selon lequel la cire est portée à une température supérieure au point de fusion et le bois thermique est introduit dans la cire liquide. La présente invention porte également sur du bois thermique imprégné de cire lequel est imprégné de cire dans sa section transversale pour au moins 30 %, de préférence pour au moins 50 % et, mieux encore, pour au moins 75 %.
