Effect of Heat Treatment on Properties of Chinese White Poplar
Chinese white poplar(Populous tomentosa Carr.) specimens were treated under a heat and steam chamber with oxygen content less than 2 percent.The effects of temperature(170~230 ℃) and time(1~5 hours) were investigated on selected physical and mechanical properties of the specimens.The results showed that increasing both the temperature and time,both dimensional stability and modulus of elasticity were improved,but the modulus of rupture decreased.
