Abstract

Agricultural straws such as rice and barley were used as partial replacement of raw materials for particleboard (PB) manufacture. A melamine-urea-formaldehyde (MUF) resin, based on 5 percent melamine addition of the resin solids weight, was synthesized in the laboratory for the bonding of PB. PBs were made using two straw particles based on 10, 20, 30, 40% oven dry weight addition with MUF resin. PBs were tested for physical and mechanical properties, and water soak dimensional stability. The results indicated that as rice and barley straws addition level were increased, the properties of IB, MOR and dimensional stabilities such as thickness swell and water absorption were decreased. Overall, the agricultural straws can be used at 15% substitution of raw materials for PB manufacture.

벼와 보리 등의 농작물 짚은 파티클보드의 원료로서 부분적으로 대체 첨가 사용할 수 있었다. 파티클보드 접착용 요소-멜라민수지 접착제를 실험실에서 수지 접착제 고형분량에 대해 5% 멜라민을 첨가하여 합성하였다. 두개의 농작물 짚을 전건 목재파티클 무게에 대해 10, 20, 30, 40% 대체하여 혼합하고 합성한 요소-멜라민수지 접착제로 파티클보드를 제조하였다. 제조된 파티클보드는 물리적, 기계적 성능과 치수안정화에 대해 성능을 비교하였다. 성능평가 결과는 파티클보드에 볏짚과 보릿짚의 대체 첨가율이 증가됨에 따라 제조한 파티클보드의 성능은 감소하는 경향을 보여줬다. 전체적으로 농작물 짚은 파티클보드 제조의 원료로서 15% 대체하여 사용할 수 있었다.
