Heat treatment of pine: Main parameters and characteristics

Heat treatment of pine is a process of thermal modification of wood, which is used to improve its physical and chemical properties. This process is carried out by treating pine wood at high temperatures in specialized chambers with a controlled atmosphere. In this article we will look at the main parameters of heat treatment of pine and its effect on the characteristics of wood.

1. Temperature:Heat treatment of pine is usually carried out in the temperature range from 160°C to 240°C. Higher temperatures can lead to more intense changes in the structure of the wood.

2. Time: The time required for heat treatment can range from several hours to several days. The duration of the process affects the depth of changes in the tree structure.

3. Humidity: To ensure effective thermal modification, the moisture content of the wood is usually kept low, most often less than 10%.

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

5. Cooling: After the heat treatment is completed, the wood remains in the chamber for gradual cooling, which avoids unwanted changes in the structure.

Heat-treated pine has a number of benefits, including increased resistance to moisture and rot, increased strength, improved aesthetics and reduced environmental impact. These characteristics make it an attractive material for a variety of applications including construction, furniture making and interior decoration.
