  • Process for treatment of wood using a carrier fluid under high pressure without damaging the wood
    Patent number: 7807224
    Abstract: A process for treatment of wood susceptible to damage and having a length that is over the critical length with a fluid under high pressure is disclosed. The process is conducted in a way so that the fluid is not allowed to enter into the liquid form inside the wood. In one embodiment the process is performed in a way so the temperature during the pressurizing is not allowed to exceed the plastification temperature of the wood. In this embodiment the rate of damages of the wood is even further reduced.
