一、沥青的胶体结构及物理特性石油沥青的组成同原油一样,相当复杂。主要由各种碳氢化合物及(氧、硫、氮等)衍生物的混合物组成。其中包括烷族碳氢化合物,环烷族碳氢化合物及芳香族碳氢化合物,这些各种各样的化合物,复杂地混合着。目前还不能将各个成分抽出来,其所含的各种物质碳与氢之原子数比H/C约为0.5~1.0,分子量约为200~6000;一般根据其碳氢比值和分子量的不同把沥青的结构成份分为主要的三部份,即
First, the colloidal structure and physical properties of asphalt The composition of petroleum asphalt, like crude oil, is quite complex. It consists of a mixture of various hydrocarbons and (oxygen, sulfur, nitrogen, etc.) derivatives. These include alkane hydrocarbons, naphthenic hydrocarbons, and aromatic hydrocarbons. These various compounds are complicatedly mixed. At present, it is still not possible to extract each component, and the ratio of carbon to hydrogen atoms of various substances contained in the material is approximately 0.5 to 1.0 and the molecular weight is approximately 200 to 6,000; generally, the ratio of carbon to hydrogen and molecular weight are different. The structural composition of asphalt is divided into three main parts:
