摘　　要：PTFE微粉化后可用于高等级润滑油中,PTFE微粉作为增稠剂的同时,可以有效增加润滑效果。本研究对PTFE废料进行了不同剂量辐照,然后对其进行微粉化处理,表征了不同实验条件下PTFE微粉的形貌、粒径以及分子量等物理性质,给出了两步法微粉化处理PTFE废料的最佳工艺条件。PTFE can be used in high-grade lubricating oil after micronization and PTFE micro powder, as well as the thickening agent, can effectively increase effect of the lubrication. The working focus different dose irradiation on the PTFE scrap then carries on the micronization process. The physical characters of PTFE micro powder prepared in different experimental conditions were measured through SEM, particle sizer and DSC. We presented a two-step micronization the best process conditions of PTFE scrap treating.
