Binderless boards were manufactured from rice straw by hot-pressing in order to evaluate the morphological
effect of particles from rice straw. For the morphological effect, we examined the influence of
particle size and morphological parts of rice straw, respectively.Internal bonding (IB), thickness swelling
(TS) and water absorption (WA) were measured as the properties of the boards. As a result, binderless
boards were successfully manufactured from rice straw powder smaller than 1mm
Regarding the effect
of morphological part from rice straw, IB of the board made from stem powder was the highest, subsequently
followed by leaf blade powder, and leaf sheath powder
