Value Adding Timber
The primary objective of this research was to 1) explore the impacts of COVID-19 on availability of, and demand for, labor in the plantation-wood processing sector in Lao PDR; 2) the Government and industry response measures to COVID-19; and 3) the impacts of 2016 Prime Ministers' Order (No. 15/PM, PMO15) aimed at addressing illegal logging and con...
ARTICLE INFO ABSTRACT The aim of this study was to assess the volume and grade recovery of veneer from plantation-grown teak using a spindleless rotary lathe. Energy consumption during peeling was also investigated. Teak logs of 3.15 m 3. Logs were peeled by using the spidleless lathe (BSY Industry Group mad in China model SL 1350/3). Research meth...
Thermo treatment on veneer has been recognized as environmentally friendly and can modify wood properties. The objectives of this study were to investigate mass loss of thermo-teak veneer, to assess the density changes, and to examine shrinkage based on different levels of temperature at different time lengths. The temperatures were 180, 200, 220,...
This research aimed to investigate the effect of solar insolation on the internal temperature of a solar kiln at different levels of relative humidity (RH=20%, RH=40% & RH=60%), and create mathematical modelling to simulate the solar kiln conditions. A solar kiln was installed at the National University of Laos, Faculty of Forest Science under the...
Providing the equilibrium moisture content values for territories is important for avoiding major problems due to dimensional changes in wooden products.
