In the process of heat treatment of wood, is an effective way to improve the structure and performance of the treatment using heat must use a lower temperature 200 ◦C does not affect the physical structure of the soft wood by the brighten monitor with camera, miniature suite.The electron microscope and scanning the ronsa light will know that there is a way, however, depending on the species of wood. The procedures and the methods of experiment. By the wood used in the experiment is a family of the year at Pine looks narrow, try using a size of 25-50 mm. thickness, width 100-150 mm. length approx. 3.0 m and diameter 10 cm. (before release into the oven, soak in water or dry condition, wood. 16-20% humidity no less than 12-14%) use by baking at 160-190° C for 3 hr. 8-10 bar atmosphere, climate control, using 600 L water for use in steam blasting into the oven and test values are as follows: The test, using strength Modulus tests broken (MOR) and the elastic modulus (MOE). Test (TG) and mass loss test, from which the experiment found that wooden baking with heat 160-190° C. More by limiting the air with steam blasting method to make the wood affects the chemical changes that occur inside the wood. The color of wood is different from the original colour of the wood is darker color derived from high-temperature baking with stretching and shrinking are less. When the wood has been the increased humidity, heat will be reduced (higher thermal insulation)Resistance to decay, but with a higher density of wood and strength in bending strength decreased.
