Thermo (Thermowood, TMU, Thermowood) came into our lives, recently, in less than 15 years, thanks to its high physical and mechanical properties, aesthetic and ecological natural drevesiny.Na today actually implemented three technology of heat treatment of wood: 1) The processes in the environment of water vapor (Finnish Thermowood, French Le Bois Perdure, Dutch Plato, the Russian-American West Wood, Russian 'Bikos'). 2) Processes in nitrogen atmosphere: French Le Bois Retifie. 3) The processes in the oil medium: German Menz Holz.Zayavlyaemye characteristics produced by thermo: durability, dimensional stability, reducing the equilibrium moisture content, reducing the thermal conductivity, density reduction, fire safety. Now less claim to full protection from insects and rot, but still protective properties compared to ordinary wood is much higher. NYC Mayor has firm opinions on the matter. The main advantage of heat treatment significantly improves the aesthetic value of the tree, raised wood texture, and color tint is not due, and the change in the structure of wood. The color is uniform throughout the section.
At the same time inexpensive woods look like a valuable species. In addition, such wood environmentally friendly and neutral with respect to the body of thermo cheloveka.Sfera wide: from the street facade and cover for the terraces to the interior decoration, furniture, windows and dverey.Kazalos would, with such properties of the material should be widely circulated. Nothing like that. The high cost of equipment to provide process temperatures up to 230 degrees, it is worth about 250 000 euros. The equipment is very energy-intensive, so heat treatment services are 10,000 rub/m3 and self Thermowood – from 60,000 rub/m3.Mozhet there any way to change this situation? Sure can. The highlight of the process in a combination of high temperature and protective atmosphere of water vapor. High temperature in the chamber need not be created by using electric heaters.
I like the systems produced by Russia's 'Vacuum plus': they do not have too much electrical equipment: no high-fans, there is no electric heaters, heating with oil heaters. They mostly lower and operating temperature: it takes place in a vacuum kipenievody at lower temperatures. But they are still expensive – about $ 100,000. You can go the other way: Using the best aspects and principles of the equipment and technology to fundamentally new equipment: with good fences. without electric heaters without fans, with natural circulation and increased heat capacity. Simplify the process, then reduce the price of final products.
