摘要： The present invention relates to improved methods of treating wooden materials. By the method of the invention, the wooden material is subjected to vacuum, overpressure and increased temperature, and subjected to ultrasound. Ultrasound is applied while the wooden material is covered by a liquid at a suitable overpressure and at a suitable temperature for a suitable period of time.

摘要： The present invention relates methods for heat treatment of wood. The invention further relates to wood obtainable by the methods of the invention as well as the use of the method for preparing treated wood. The method comprises the step of pressurising said airtight tank (4) to a predefined pressure (P1) in order to establish a pressurised environment for said wood (6). The method comprises the step of placing said wood (6) in an airtight tank (4) and heating said wood (6) to a predefined temperature (T2, T3). The predefined pressure (P1) is kept so high that the water in the wood (6) cannot evaporate at the predefined temperature (T2, T3).
