The crystalline structure changes of pp induced by pan - milling were characterized by x - ray diffraction and raman spectroscopy. xrd analyses show that when pp was co - milled with uhmwpe, crystal transformation of pp occurred, its crystallinity and crystallite size decreased, whereas, only slight reduction of crystallinity and crystallite size were observed and no crystal transformation was found when pp was co - milled with wtr chips, and amorphization of pp was strongly enhanced by co - milling pp with iron

研究了金屬茂催化的低分子量支化聚乙烯和線性聚乙烯的結晶及熔融行為,發現支化聚乙烯的結構與線性聚乙烯相同為正交結構,但晶格略有膨脹.支鏈的存在對熔融行為影響不大,兩種聚乙烯的熔點均隨結晶溫度的升高而非線性增加,表現出低分子量樣品的共同特徵.但支鏈的存在對結晶行為卻有很大的影響,主要是由於支鏈的存在降低了晶體的結晶速率從而影響結晶過程,使得低分子量的支化聚乙烯的結晶行為與高分子量線性聚乙烯的結晶行為相似而與低分子量的線性聚乙烯不同.動力學分析表明,低分子量的支化聚乙烯的結晶生長方式的轉變溫度比同等分子量的線性聚乙烯降低了約20The degrees of crystallinity of pure ptfe under the different conditions of water cooling, air cooling and furnace - varying cooling were made comparison by xrd. the thermal stability of pure ptfe and solid lubricant was analyzed by dsc - tg ; the composition and valence state of elements in the surface of carbon fiber, solid lubricant before and after friction test and lubricant transfer film were characterized by xps ; the frictional property of solid lubricant was tested by pin and disk test rig. the frictional wear property of solid lubricant between embedded bearing sleeve and steel axle friction pair ring was tested by special simulate test machine, the hardness of solid lubricant was tested by pm ; the compression strength of solid lubricant was tested by material test machine
