摘要: 以废旧聚乙烯和聚丙烯塑料及中石渣作为原料,采用模压成型工艺与挤出成型工艺制造复合模板。对2种成型工艺所得模板样品的宏观形貌与力学性能进行了比较。结果表明,挤出成型工艺更适合复合模板的成型加工,挤出成型工艺生产的模板宏观形貌致密、均匀,冲击强度、弯曲强度、弹性模量比模压成型工艺所得模板分别捍高了29. 8%,36. 6%,25. 9%。

Abstract: Compound formworks were made from waste plastics (PE,PP) and carbide slag,and two molding methods,hotpressing and extrusion were compared. It showed that the extrusion molding was superior to hotpressing, dense and even-texture,better mechanical properties were obtained. The impact strength,the flexural strength,and the elasticity modules of the extrusion based formworks were 29. 8%,36. 6%,and 25. 9% higher than those based on hotpressing molding.
