Abstract
Rice husk (RH) is a major waste byproduct of global rice paddy production. Powdered RH is mixed with a polymeric resin to produce RH-based medium density board. Resin concentration is varied and several particles sizes of RH powder are tested. The RH powder is subjected to acidic, neutral, and alkaline treatments to determine how they affect adhesion of the resin to the powder. The adhesion controls, to a large extent, the mechanical and tribological performance. Thus, mechanical and tribological properties of fiberboards prepared from untreated RH powder are compared to treated specimens and the effects of pH are determined. The mechanical performance of the RH-based MDF compares favorably to similar commercial building materials.
