摘要

刨花板是一种在压力和温度下由木材颗粒或其他任何木质纤维素纤维材料和粘合剂制成的人造板产品。刨花板制造对生态无害,因为废料将转化为有用的产品,从而节约自然资源。本研究以Woniji-Shewa糖厂为例,以蔗渣为原料生产和评价刨花板。蔗渣颗粒表面与核心层的比例为1:2:1。按下时间有5、7、12min三个级别。树脂比为7、12和15%。采用design Expert 7.0.0软件的全因子设计(FFD)对刨花板的制作进行了研究,确定了刨花板抗弯强度(MOR)的最优值。分析、理化性质及实验结果;0.68g/ cm3,密度48.1%,水分含量2.37%,灰分含量61%,挥发物含量36.63%,固定碳8.06KJ/kg,热值1.12%,pol 2.86%,糖度44.17%,纤维含量27.16%,半纤维素21.5%,木质素39.33%,纤维素。当树脂比为14.63%、压制时间为8.45min时,刨花板的最大抗折强度为27.4N/mm 2。板材温度为153.73℃,利用甘蔗渣生产刨花板是可行的,也是环保的。

Production and Evaluation of Particleboard using Sugarcane Bagasse in the case of Woniji-Shewa Sugar Factory
Particleboard is a wood-based panel product manufactured under pressure and temperature from the particles of wood or other any lignocellulosic fibrous materials and a binder. Particleboard manufacturing is ecologically sound, as the waste material will transform into useful products, thereby conserving natural resources. The objectives of this study was production and evaluation of particleboard using sugarcane bagasse in the case of Woniji-Shewa Sugar Factory. The ratio of the surface and the core layer of bagasse particles were 1:2:1 ratio. A three levels of press time 5, 7 and 12min. and resin ratio 7, 12 and 15%. Besides, plate temperature were selected 140, 150 and 160 0 C. Making of particleboard were investigated by a full factorial design (FFD) that was a Design Expert 7.0.0 software and determined an optimal value of the bending strength (MOR) of particleboard. For analyzing, physiochemical properties and result obtained from experiments; 0.68g/cm 3 , density, 48.1%, moisture content, 2.37%, ash content, 61%, volatile mater content, 36.63%, fixed carbon, 8.06KJ/kg, calorific value, 1.12%, pol, 2.86%, brix, 44.17%, fiber content, 27.16%, hemicellulose, 21.5%, lignin, 39.33%, cellulose. A maximum bending strength of particleboard was 27.4N/mm 2 obtained at a resin ratio, 14.63%, pressing time, 8.45min. and plate temperature 153.73 o C. Based on the finding, manufacturing of particleboard using sugarcane bagasse were achievable and environmentally friendly.
