• asphaltene是什么意思？

Asphaltenes是瀝青質(zhì)的意思。

瀝青質(zhì)是瀝青中的高分子碳氫化合物，是石油瀝青中的核心成分，也是區(qū)分石油瀝青等級的一個重要參數(shù)。瀝青質(zhì)含量越高，瀝青的顏色越深，粘度越大，塑性越小，脆性越大，高沸點成分越多，則粘附性越好。在石油瀝青中，由于分子結(jié)構(gòu)的原因，往往存在一些膠質(zhì)和瀝青質(zhì)。這些物質(zhì)在高溫時易溶于石油醚或汽油中，使石油瀝青具有可塑性、粘性和流動性。隨著溫度的變化，瀝青質(zhì)從油中析出并形成薄膜，使石油瀝青具有彈性。因此，瀝青質(zhì)在石油瀝青的性質(zhì)和性能中起著重要的作用。
