Tribological Property of Polyimide Porous Materials

Polyi mide(PI)is a kind of macromolecule mate-rial developed since the1950s,having superior physi-cal mechanical properties,resistance to hightempera-ture,resistance to acid and alkali,and excellent selflubricating property.Hence,it is widely applied inhigh and new-technology fields,such as the militaryindustry,electronic industry and aerospace indus-try[1].However,in the current research on the fric-tion performance of PI materials,the most concernedtopic is PI fil m materials,and it is sel…     

石墨对聚四氟乙烯（PTFE）抗静电性能的影响

采用冷压成型、热压烧结工艺制备石墨改性聚四氟乙烯（PTFE）复合材料,利用MS—T3000摩擦磨损试验仪和EST102A振动电容式静电计检测摩擦过程中产生的静电电压,并研究了石墨粒径、添加量对PTFE复合材料抗静电性能的影响。试验结果表明,添加石墨可以改善PTFE复合材料的抗静电性能,且添加小粒径石墨（4μm）的效果要明显优于添加大粒径石墨（30μm）的效果,当石墨含量（4μm）为5％时,抗静电性能最优,摩擦过程的静电电压接近于0V。     

“人间天堂”看洪湖

一曲洪湖水,唱醉万人心。镶嵌在长江北岸 的江汉明珠--洪湖市,是一座因湖得名、因水闻名的以轻纺、建材、化工、机械、水产品养殖加工为主的新型工业城市和具有一定资源的旅游城市。全市国土面积２５２８平方公里,其中水域面积约占三分之一,全市总人口９０．７万,其中城镇人口 ２５．４万。 １９９５年以来,洪湖市遭遇"四年三水"的特大洪涝灾害,９０万洪湖人民奋力抗灾,在洪灾后重建家园,确保了灾后经济迅速恢复和发展。１９９９年,实现国内生产总值４２．３亿元,财政收入２．３２亿元。经济的高速发展,有力地促进了城市建设。…     

Effects of Forming Pressure on the Porosity of Polyimide Porous Materials

Based on a series of experiments, the theory of relationship between normal pressure and pores＇ characters fit for polymer was set up for the first time. On the study of relation between normal pressure and porosity, experience model of polyimide porous materials was proposed which is similar to the traditional expe- rience model of the metal porous material. While being pressed, polyimide was found soon to come into elasto- plastic deformation progress in this paper, so the theory model of metal porous material based on Hooker＇s law was not fit for the polymer any more. A new elasto-plastic deformation and exhausting model is proposed which shows better agreement with polymer material＇s pressing process.
