Embodiment Construction
[0026] The invention collects andesite, basaltic andesite, tholeiitic basalt and alkaline basalt from four different regions in China. First determine the chemical composition and mineral composition of each basalt ore CBF1, CBF2, CBF3 and CBF4, and then prepare basalt glass and monofilament. Finally, the melting process parameters, fiber forming process parameters and tensile strength are determined. The composition, melting process parameters and fiber forming process parameters of basalt are shown in Table 1 and Table 2.
[0027] Chemical composition (wt%) of table 1 basalt
[0028] chemical composition
[0029] Mineral composition (wt%) of table 2 basalt
[0030] mineral composition
[0031] Among the four groups of basalt ores, SiO 2 The contents are respectively (wt%): 57.5, 54.12, 51.79 and 46.45. SiO of the fourth group of basalt ores 2 The content is not within 48-63%. Meanwhile, the composition of the fourth group of basalt ores contains oli...
