【摘要】 研究植物纤维类缓冲包装材料的2种成型工艺:螺杆挤压膨化成型工艺、发泡膨化成型工艺。螺杆挤压膨化是指原料通过螺旋推进的方式,形成压力差,使植物纤维膨化。植物纤维发泡膨化成型的工艺有两种,分别是使用化学添加剂和不使用化学添加剂。更多还原

【Abstract】 Two molding techniques were developed,which were screw extrusion molding and froth molding.The first technique is that the raw material is pushed by screw to form pressure difference and make plant fiber expanded.The technique of plant fiber forth molding includes using chemical additive and not- using chemical additive.更多还原
