电极粘结剂沥青——生产阳极的一种主要原料,原料、生产、应用及运输方面的发展趋势

ELECTRODE BINDER PITCHES AN ESSENTIAL RAW MATERIAL FOR ANODE MANING TRENDS IN RAW MATERIALS, MANUFACTURING, APPLICATION AND TRANSPORTATION

煤沥青本身的化学结构使其特别适合作为生产阳极的粘结剂。概述了在原料、煤焦油到粘结剂沥青的加工及新的运输系统等方面的最新发展趋势。新制定的分析和试验方法和先进的处理工艺相结合,提高了粘结剂沥青的质量以满足铝生产对阳极越来越苛刻的要求。

Due to their chemical structure coal tar pitches are especially suited as binders for the manufacturing of anodes. Recent trends in raw materials, in processing of crude coal tar to binder pitches and in new transportation systems are outlined. By newly developed analytical and testing methods in combination with advanced processing technology, improved binder pitch qualities are made available in order to meet the increasingly stringent requirements for anodes in aluminium production.
