摘要
采用销-盘摩擦副接触方式,在常温、无润滑下,对常用的建筑用聚四氟乙烯(PTFE)、聚偏氟乙烯(PVDF)、聚氟乙烯(PVF)、氟树脂膜进行摩擦磨损试验,研究和分析不同载荷和滑动速度下3种氟树脂膜的摩擦学特性。通过摩擦因数变化关系和磨损表面形貌分析解析不同氟树脂模的磨损机制。研究结果表明,PVF膜材摩擦因数最大,PTFE膜材次之,PVDF膜材摩擦性能最好;PVF膜材磨损量最大,PVDF膜材次之,PTFE膜材磨损量最小,显示出最好的耐磨性;树脂膜开始剥离和严重磨损时所能承受的载荷,PTFE膜材为60N,PVDF膜材为22N,PVF膜材为14N,即PTFE膜材具有最好的耐久性。
The friction and wear experiments were carried out for the common architectural fluorine resin membranes PTFE,PVF,PVDF with the mode of pin-on-disc friction pair contact at normal temperature and unlubricated condition.is used for carrying out The friction and wear experiment of the common architectural fluorine resin membranes PTFE,PVF,PVDF at normal temperature and non-lubricated. Analysed and studied the tribological properties of different fluorine resin membranes in different load and sliding speed. The wear mechanism of the different fluorine resin membranes were analysed through the relation between friction coefficient and wear surface topography.The result shows that the friction coefficient of PVF is maximum and PTFE secondarily.The friction property of PVDF is the best. The wearing capacities of PVF,PVDF and PTFE were 0.22 g ,0.20 g and 0.12 g respectively,so the wear resistance of PTFE is the best. The capacity of bearing load of PTFE,PVDF and PVF were 60 N,22 N and 14 N respectively when the resin film starts peeling and severe wearing,so PTFE has the best durability.
