Color and Chemical Changes in Teak (Tectona grandis L. f.) and Meranti (Shorea spp.) Wood after Thermal Treatment

Popis výsledku v původním jazyce

This paper studied the effect of thermal treatment (160 degrees C, 180 degrees C, and 210 degrees C), based on ThermoWood (R) principle, on the color and chemical properties of teak (Tectona grandis L. f.) and meranti (Shorea spp.) wood. The color of the wood was determined using the CIE Lab system before and after the thermal treatment and was evaluated according to the total color change. The chemical changes were evaluated by wet chemical methods. The lightness of the wood was most affected during treatment. Meranti wood became darker (46,1%) compared with the teak wood (41,8%). The red-green and yellow-blue coordinates were higher in the teak wood, and their values decreased as the thermal treatment temperature increased in both wood species compared with untreated wood. The color change was higher in the meranti wood, and it increased steadily with increasing temperature. The extractives, cellulose, and lignin percentage contents increased in both wood species, however, the highest treatment tem
