DescriptionThe main objective of this study is to evaluate the effect the oxalic acid (OA) and steam pretreatment on the primary properties of rice straw medium-density fiberboard (MDF). The results show the IB strength increased about 9.6% and 13.4% for steam-treated MDF (PC) and OA-treated MDF compared with raw control panels, while OA pretreatment has a slight negative effect on the bending properties of MDF. Generally, the steam-treated and OA-treated panels exhibit a slightly improved dimensional stability, but the difference is not significant compared with raw control panels. The thermo-mechanical defibration process is the main factor to improve the bond-ability between UF resin and rice straw, which resulted in good quality rice straw MDF. The mechanical strength of rice straw MDF can meet ANSI standard for interior MDF, but the LE and TS of MDF without paraffin wax addition is lower than the minimal requirement of the ANSI standard. MDF is one of the most feasible products for utilizing rice straw.
