Heat treatment of alder: Main parameters and characteristics

Heat treatment of alder 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 alder 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: Optimum temperature ranges for heat treating alder typically range from 180°C to 220°C. Adjusting the temperature allows you to achieve the desired changes in the properties of the wood.

2. Time: The duration of heat treatment of alder depends on the specific requirements of the project and can vary from several hours to several days. Long periods can lead to more profound changes in the structure of the wood.

3. Moisture: Reducing wood moisture to less than 10% is an important aspect of thermal modification, ensuring the efficiency of the process.

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

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

Heat treatment of alder gives the wood improved properties, such as increased resistance to moisture, resistance to rot and changes in mechanical characteristics. These improvements make heat-treated alder a sought-after material in construction, furniture manufacturing, and other industries that require high-quality, sustainable wood.
