The Effect of Heat Treatment on Physical, Chemical, Mechanical and Biological Properties of Wood

Ahşabın Fiziksel, Kimyasal, Mekaniksel ve Biyolojik Özellikleri Üzerine Isıyla Muamelenin Etkisi

Abstract

Since ancient times, heating wood has been used a method to dry and modify its properties. Nowadays, heattreatment is used in industrial processes for the same reasons. Treatment at temperatures above 150 °C canchange the color, improve resistance to biodegradation and enhance dimensional stability. However, losses in themechanical and technological strength of wood may also occur, and this drawback is a limitation for the use ofheat-treated wood in a broad range of products. The treatment method used in the world is called “Thermowood”and this method can industrially applied in Finland. The method involves heating wood in a steam atmospherewhere the heat causes chemical changes in the structure of the wood. In this study, the effect of heat treatment onwood properties was investigated.
