Abstract: This paper researched on Australian Eucalyptus regnans drying properties by 100°C Test Method, also researched 25mm-thick boards dried by air-kiln drying schedule. The result indicated that the species belongs to refractory wood when drying, with checks and collapse defects that develop easily. In order to improve the drying quality, we adopted the method of first air-drying the moisture content (MC) to four different ranges and then kiln-drying. The two phrase air-kiln drying schedule concluded that the drying cycle of 25mm-thick Eucalyptus regnans board from 76.34% to 13.11% MC was 33.5 days, and the drying quality of visible defect met the requirement for the first level of the Chinese national standards.

Abstract: Influence of the ratio of raw materials on the extrusive property and drying performance of the terracotta panel was investigated by the thermo-gravimetry, differential thermal analysis (TG-DTA) and SEM methods. The results show that the optimization extrusion property of paste body and drying behavior can be achieved by the ratio of plastic and non-plastic materials is 45:55.
