本文叙述了用MИM—8大型卧式显微镜观察研究了生坯、焙烧、石墨化的炭黑基、焦碳基和石墨基三种试样中粘结剂沥青的形态。 此外,本文根据焙烧前和焙烧后的试样的金相结构变化,提出在焙烧过程中对焙烧后粘结剂焦碳形态有重要影响过程是:伴随着粘结剂的流动,产生一个对基体碳素材料颗粒表面有选择性的化学吸附过程。这一过程决定了粘结剂焦碳的基本形态。
This article describes the use of MITM-8 large horizontal microscope observation of green, calcined, graphitized carbon black, coke and graphite-based three samples binder asphalt morphology. In addition, based on the changes of the microstructure of the samples before and after calcination, we propose that the calcination of the binder during calcination has an important influence on the morphology of the coke. With the flow of the binder, Carbon material particle surface selective chemical adsorption process. This process determines the basic form of binder coke.
