石棉是一种纤维结构的非金属,可分蛇纹石石棉(温石棉)和角闪石石棉,角闪石石棉又分青石棉(蓝石棉),铁石棉,直闪石石棉和透闪石石棉。温石棉主要用于纺织制品,蓝石棉还可做过滤材料,铁石棉用于绝缘和建材。评价石棉主要依据类型、纤维长度和物化工艺性能。我国石棉储量较多,66%集中于青海和四川两地,但长纤维含量较少,加工过程纤维损伤也较严重,此外陕西、辽宁、云南也有。寻找石棉的带用品是国外发展的方向,但还不能完全取代,主要原因是:代用品制造复杂,成本高;代用品也是有害物质;从物化性能上完全取代不可能。因此,应根据我国石棉优势,采取积极稳步方针,加强防尘措施,提高产品质量,打入国际市场。
Asbestos is a non metal fiber structure, can be divided into serpentine asbestos (chrysotile) and amphibole asbestos, amphibole asbestos divides crocidolite, amosite (Lan Shimian), anthophyllite and tremolite asbestos. Chrysotile is mainly used for textile products, blue asbestos can also be used as filtering material, amosite for insulation and building materials. Evaluation mainly according to the type of asbestos, fiber length and physicochemical process performance. Asbestos more reserves in our country, 66% concentrated in Qinghai and Sichuan two, but the long fiber content is less, the machining process of fiber damage is more serious, in addition to Shaanxi, Liaoning, Yunnan also has. Looking for asbestos with activities is the overseas development direction, but also can not completely replace, the main reason is: substitute manufacturing complex, high cost; substitute is harmful substances; physical performance completely replace the impossible. Therefore, should be based on the advantages of asbestos in China, take positive and steady policy, strengthen the dust control measures, improve the quality of products, to enter the international market.
