一、前言随着热电工业的迅速发展,粉煤灰这种工业废渣的排放量越来越大,严重污染了环境。许多国家都在研究开发利用这种废渣,变废为保,用作橡胶、塑料、陶瓷、水泥的填加剂,均取得可喜成果。用粉煤灰代替滑石粉用作生产沥青油毡的沥青填充料,既可降低生产成本又减少了环境污染同时提 I. INTRODUCTION With the rapid development of the thermoelectric industry, the emission of fly ash, an industrial waste residue, is increasing and it has seriously polluted the environment. Many countries are researching and developing this kind of waste residue, turning waste into preservation, and used as rubber, plastics, ceramics, and cement fillers, and all have made gratifying achievements. The use of fly ash instead of talc powder as an asphalt filler for the production of bitumen felt can reduce production costs and reduce environmental pollution.
