    • Basalt filament is manufactured such that the fiber diameter can be controlled and the filament is not severed during winding. A network former and a glass modifier are formed and maintained with respect to basalt rock ore, and the crystallization and binding of basalt fiber are inhibited, the heat-resistance property of basalt fiber is greatly improved from the conventional 750° C. to 850 or 900° C., and significant cost reduction is achieved over conventional products. The method includes: grinding basalt rock as a material; washing a resultant ground rock; melting the ground rock that has been washed; transforming a molten product into fiber; and drawing the fiber in an aligned manner, and winding it. The temperature of the molten product in the melting step is 1400 to 1650° C., and log η is 2.15 to 2.35 dPa·s and preferably 2.2 to 2.3 dPa·s, where η is the viscosity of the molten product.
    • 制造玄武岩丝,使得可以控制纤维直径,并且在缠绕期间丝不被切断。 相对于玄武岩岩石矿形成并保持了网络成型体和玻璃改性剂,并且抑制了玄武岩纤维的结晶和结合,玄武岩纤维的耐热性能从传统的750℃大大提高到850或 900℃,并且比常规产品显着降低成本。 该方法包括:将玄武岩岩石作为材料研磨; 清洗所得的地面岩石; 熔化被洗涤的地面岩石; 将熔融产物转化成纤维; 并以对准的方式绘制纤维,并将其卷绕。 熔融步骤中的熔融产物的温度为1400至1650℃,log eta为2.15至2.35dPa·s,优选为2.2至2.3dPa·s,其中η为熔融产物的粘度。
