Wood processing methods change over time. One of the latest achievements in this area is considered to be thermal processing of wood through steam. The very first experiments on the similar processing of wood were carried out in the 30s of the XX century in Germany. This issue gradually began to be interested in other countries. The heat treatment of wood with high temperatures significantly changes its structure, leading to improvement of certain parameters. Such wood processing allows you to destroy, for example, the polysaccharides, the polysaccharides contained in it are destroyed, which prevents the formation of mold and various fungi. Currently, 3 wood heat treatment options are known:
1. Heat treatment over 180 ° C. In this case, the decorative qualities of wood improve.
2.Heat treatment over 210 ° C. In this case, the resistance of wood of rotting increases significantly.
3.Heat treatment over 230 ° C. In this case, stability of size is acquired, increased resistance to decay, durability.
Wood, which is processed by steam, for example, thermo ash, has practically all the same properties as a chemical way of wood, which, as you know, is an unecilal and dangerous for human health. Thermodrevsina (thermo ash, for example) is very environmentally friendly. This method of wood processing is becoming more and more popular day.
The main advantages of thermal conventions include:
sizes stability;
moisture -repellent properties;
environmental friendliness;
wear resistance;
Fire resistance.
Aesthetic appearance.
Disadvantages of thermal -breeds:
exposure to ultraviolet;
Specific smell,
High cost.
Thermally processed wood is an excellent building material that can be used in all types of decoration, as well as in various construction work, as well as raw wood.
Tests carried out in laboratory conditions have proved that the heat treatment of wood is significantly stability of the tree to biological lesions. In the wood, due to high treatment temperatures, polysaccharides decompose, which eliminates the conditions for the propagation and occurrence of microorganisms and fungus against the background of low equilibrium humidity. Thermodrevsin can be used in works requiring the stability of dimensional characteristics from materials.
