【摘要】 近年来连续玄武岩纤维凭借绿色的生产工艺和优异的性能得到国内外广泛关注，但玄武岩原料不均一性成为限制其发展的重要原因。四川省玄武岩储量巨大，在会理、峨眉、盐源等地广泛分布，具有极大的应用潜力与经济价值。但各地玄武岩化学组成变化大且当前对玄武岩矿石的质量评价标准尚不统一，影响了玄武岩纤维的开发利用。通过总结省内连续纤维用玄武岩原料研究现状，对不同地区玄武岩矿石的岩石特征、矿物特征与化学组成进行梳理，分析国内外部分生产企业及研究人员采用的玄武岩化学成分指标，为四川玄武岩纤维原料筛选服务。研究表明用作玄武岩纤维原料的矿石以致密块状玄武岩为主，部分斑状玄武岩为辅以及少量细粒辉长岩；多具斑状结构，基质具间粒间隐结构，块状构造；化学成分变化范围大，多具高Fe低碱特征。更多还原

【Abstract】 In recent years, continuous basalt fiber has received widespread attention both domestically and internationally due to its green production processes and excellent performance. However, the heterogeneity of basalt raw materials has become an important reason limiting its development. Basalt reserves are huge and widely in Sichuan Province, which is distributed in Huili, Emei, Yanyuan, etc., possessing great potential for application and economic value. However, the chemical composition of basalt varies greatly from place to place and the current quality evaluation standard of basalt ore is not uniform, which affects the development and utilization of basalt fiber. By summarizing the current research status of basalt raw materials for continuous fibers in Sichuan Province, this paper sorts out the rock characteristics, mineral characteristics, and chemical composition of basalt ores in different regions, and analyzes the chemical composition indicators of basalt using by some domestic and foreign production enterprises and researchers, and provides services for the screening of basalt fiber raw materials in Sichuan Province. Research has shown that the ore used as raw materials for basalt fibers is mainly composed of dense block basalt, part of porphyritic basalt as well as a small amount of fine-grained gabbro; mostly with a porphyritic structure, matrix with intergranular cryptic structure, blocky structure; the chemical composition of the wide range of variations, most of them have a high Fe and low alkali characteristics.更多还原
