Effects of pretreatment methods on properties of corn straw board

  • 摘要: 采用HCl、NaOH、热水、羧甲基纤维素钠(CMC)及果胶对玉米秸秆进行预处理,并通过热压法制备轻质玉米秸秆人造板,研究单一预处理和复合预处理对玉米秸秆表面润湿性、表面微观形貌、热稳定性以及板材力学性能的影响。结果表明:各个单一预处理条件均能降低玉米秸秆纤维与水的接触角,预处理后玉米秸秆束外皮表层形貌由平滑变为粗糙,表层破裂脱落,表面硅元素质量分数明显下降,NaOH处理对玉米秸秆表面润湿性改善最佳。热稳定性分析表明:在热压温度150 ℃下,预处理玉米秸秆纤维结构稳定,无明显热分解趋势。各个预处理条件均能改善玉米秸秆人造板的力学强度,复合预处理条件不能在单一预处理的基础上进一步提高板材的力学性能。HCl、NaOH及水热预处理会减弱玉米秸秆纤维结构强度,使得秸秆纤维结构强度对人造板力学性能的影响大于界面胶合强度。水热处理后秸秆人造板力学性能改善最明显,IB值提高了700.0%,MOR值提高了112.5%,MOE值提高了87.5%。
