摘　　要：对盐津地区的玄武岩是否成纤以及成纤后的耐酸碱性能进行了研究,利用X射线能谱仪分析盐津玄武岩纤维的组成,利用电子单纤维强度仪测试纤维的抗拉强度,利用扫描电子显微镜和傅里叶红外光谱仪来表征纤维表面形貌和结构组成,利用X射线衍射仪来研究纤维的晶相结构。结果表明:盐津玄武岩纤维的成纤温度较低,在1 320℃、400 r/min条件下可达到最大流量;未经处理的纤维表面非常光滑,呈现一种近程有序、远程无序的玻璃态状态;单丝抗拉强度接近1 000 MPa;纤维的耐酸性能优于耐碱性能。Whether the basalt in YanJin area has fiber-forming performance and the acid and alkali resistance performance after fiber-forming were studied. The fiber composition of basalt fiber in Yanjin area was analyzed by X-ray energy dispersive spectrometer, the tensile strength of fiber was measured by electronic single-fiber strength tester, the surface morphology and structure of the fiber were characterized by scanning electron microscope and Fourier transform infrared spectrometer, and the crystal phase structure of the fiber was studied by X-ray diffrotometer. The results show that the fiber-forming temperature of the basalt fiber in Yanjin area is low, and the maximum flow rate can be reached at 1 320 ℃ and 400 r/min;the surface of the untreated fiber is very smooth, showing a kind of glass state with near-range order and long-range disorder;the acid resistance performance of the fiber is better than that of alkali resistance performance.
