Thermal modification wood processing technologyadmin
In the 20th century 80 s, has hot modified wood began to mass production, at the same time, also just in order to make wood has better combustion values, makes the energy value of wood combustion is higher. So, baking technology in wood,prompting the combustibility of lumber is better, to achieve the goal ofcompletely replace charcoal. But in the process of sustainable development research, related people come to realize that, after baking processing timber,reflects the extremely good durability, corrosion, the hardness of both thestability of the wood and wood, has greatly improved, so people began to fully use this kind of material is applied to the buildings.
Thermal modification wood, there are 2 kinds of production technology, namely Retification and Perdure. The former is to wood drying to the average moisture content of 12%, then in nitrogen (oxygen content is not higher than 2%) heating to 210 ~ 240 ℃, the wood in the inert gas environment hemicellulose, cellulose and lignin pyrolysis and change, improve the dimensional stability of lumber and corrosion resistance; The latter is the log after drying, the steam heated to 230℃, the hardness and compression resistance of lumber, wear-resisting performance is improved greatly; Moth-proofing, anti-corrosion, moisture-proof, degreasing,prolong the service life of the wood, and keep natural flavor, etc.
