• 中文摘要： 本研究是以機械融熔混煉方式製備兩種聚縮醛/鐵氟龍混煉物,並測試這些混煉物的機械、物理、磨耗、介電、動態黏彈和形態等諸性質,由以上測試結果顯示,聚縮醛/鐵氟龍屬不相容系,在Taber磨耗因子方面,當鐵氟龍添加入聚縮醛後,對M90系而言,Taber磨耗因子由 288降至75,而對M270系而言,Taber磨耗因子則由326降至68.5。此顯示當鐵氟龍添加入聚縮醛後可提升聚縮醛的耐磨耗性,另由研究混煉物表面的磨耗形態得知,聚縮醛的磨耗機構是屬脆性磨耗機構,而添加鐵氟龍後,聚縮醛/鐵氟龍的磨耗機構則屬韌性磨耗機構。
• 英文摘要： Two kinds of plastic blends; polyacetal (POM) and polytetrafluoroethylene (PTFE) have been prepared by mechanical blending. A detailed description of the preparation of these samples is given. The mechanical, physical, wear, dielectrical, dynamic mechanical, and morphology properties of these samples have been measured. The results indicate incompatibility between POM and PTFE. The Taber wear factor of POM decreased from 288 to 75 for M90 and 326 to 68.5 for M270. The worn surface morphology explains the mechanism of wear. It was found that the incorporation of PTFE increases the wear resistance of POM, and the wear mechanism changes from a brittle type of wear mechanism to a ductile type of wear mechanism.
