在我国角闪石类石棉的蕴藏量极为丰富。然而,这类石棉在工业上的应用没有引起重视。将近二十多年以来,我了解到的一些情况,粗浅地谈谈这类石棉在工业上的评价及开发利用问题。石棉分蛇纹石石棉和角闪石石棉两大类。角闪石类石棉(耐酸石棉)具有较高的耐酸、碱性和化学稳定性。其中兰石棉还具有制造防化学毒物过滤器和净化被放射元素污染的空气等重要特性。这一类石棉中,除兰石棉纤维细而柔韧可作纺织外,其它例如:直闪石,铁石棉,透闪石、阳起石等石棉,有的纤维硬脆劈分性能差,有的纤维虽
The amphibole asbestos in our country is extremely rich in reserves. However, the industrial application of this type of asbestos has not attracted much attention. For nearly two decades, I have learned some of the situations and briefly talked about the industrial evaluation and development and utilization of such asbestos. Asbestos sub-serpentine asbestos and amphibole asbestos two categories. Amphiboles Asbestos (acid asbestos) has a high acid, alkaline and chemical stability. Among them, blue asbestos also has important features such as making chemical-resistant filters and purifying air contaminated with radioactive elements. In this type of asbestos, in addition to fine and flexible asbestos fiber can be used for textile, other examples: asbestos, amosite, tremolite, emerald asbestos and other asbestos, and some fiber hard brittle splitting performance, and some Although the fiber
