【摘要】 采用冷压成型和自由烧结工艺研制开发出了一种具有优良密封性能的新型玻璃微珠填充改性聚四氟乙烯(PTFE)密封材料。通过分析测试,深入研究了玻璃微珠对PTFE密封材料性能的影响。结果表明, 玻璃微珠对改性PTFE 密封材料的性能有较大影响,当玻璃微珠质量分数在30%左右且粒度较小时,PTFE密封材料综合性能较佳。更多还原

【Abstract】 Glass microballoon filled PTFE sealing materials was developed by die pressing and sintering Test results showed the new kind of filled PTFE has good sealing performance On the basis of the test, the influence of glass microballon on property of PTFE sealing materials has been studied The study revealed that glass microballon had great effect on the performance of PTFE The general properties of the material were very good when the percentage composition of glass microballoon was about 30% while the particle of glass microballon was very fine更多还原
