Examples
- The paper focuses on the processing technique of wood flour - recycle polystyrene composite , and assesses the effects of wood flour contents , coupling agent contents and the rotate speeds of extruder on water uptake , tension strength , bending strength and dynamic mechanical properties . the results can be shown as follows : with the increasing of wood flour , composites gain higher water uptake but lower dynamic mechanical properties , the storage moduli ( e " ) and glass transition temperature ( tg ) decrease
较系统地研究了木粉含量、偶联剂添加量和双螺杆挤出机的螺杆转速等主要挤出工艺参数对复合材料的吸水性能、拉伸强度、弯曲强度、动态机械性质(存储模量e和损耗正切角tan )的影响规律，初步确定了适宜工艺条件，主要结论是： 1 )木粉含量的增加使得复合材料的吸水性能增加，动态机械性质下降。
