The features of all flakes were with crude surfaces. The flake’s aligned angle on the face layer of OSB within 0 ∘-30 ∘ accumulated to 74-92% of the total flakes. The ultrasonic velocity (V) at 0 ∘of aligned angle (V0) was the highest, decreased rapidly with increasing aligned angle. There were significant positive relationships between velocity and MOR, MOE, MOEdv, IB, SH. In drill resistance test, the PD, MD affected on properties of bending strength positively while Pdi affected on properties of bending strength negatively. All of its physical and mechanical properties met the standard as specified in CNS 2215 30-15 type and 24-10 type of particleboard. Song-Yung Wang 王松永 2004 學位論文 ; thesis 73 zh-TW |
