Thermal Treatment of Pine: Key Parameters and Characteristics

Wood thermal treatment is a process of thermal modification applied to enhance the physical and chemical properties of wood. This process involves treating pine wood at high temperatures in specialized chambers with a controlled atmosphere. In this article, we will explore the key parameters of thermal treatment for pine and its impact on wood characteristics.

1. Temperature: Thermal treatment of pine is typically conducted in a temperature range from 160°C to 240°C. Higher temperatures may lead to more intense changes in the wood structure.

2. Time: The duration of thermal treatment can vary from several hours to several days. The length of the process influences the depth of changes in the wood structure.

3. Humidity: To ensure effective thermal modification, the wood’s moisture content is typically maintained at a low level, often below 10%.

4. Atmosphere: The thermal treatment process can be carried out in a nitrogen or steam atmosphere to prevent wood oxidation and other undesirable chemical reactions.

5. Cooling: After the thermal treatment, the wood undergoes a controlled cooling process to stabilize its structure and prevent rapid changes.

Thermally treated pine offers several advantages, including increased resistance to moisture and decay, enhanced strength, improved aesthetic characteristics, and reduced environmental impact. These features make it an attractive material for various applications, including construction, furniture manufacturing, and interior finishing.
