Embodiment 1
[0032] 1) Immerse 100kg of basalt ore in a pool, wash it, remove impurities that may be attached to the surface, then take it out to dry, and crush the dried basalt ore with a pulverizer to a fineness of 2mm to obtain basalt ore powder;
[0033] 2) Ball mill and mix the basalt ore powder obtained in step 1) with 0.001 kg of graphene for 1 hour, and discharge after mixing evenly to obtain the mixed powder;
[0034] 3) Add the mixed powder obtained in step 2) into the kiln, and feed nitrogen into the kiln, raise the temperature to 1300°C, and stir at the same time, so that the basalt powder is completely melted, and the modifier is uniformly dispersed and suspended in the basalt A spinning melt is formed in the melt;
[0035] 4) Drawing the spinning melt obtained in step 3) with a platinum-rhodium alloy drawing bushing with 200 holes and a temperature of 1200°C at a speed of 1500m / min to obtain basalt fiber precursors;
[0036] 5) The raw silk obtained in step 4) is unwound and...
Embodiment 2
[0040]1) Immerse 100kg of basalt ore in a pool, wash it, remove impurities that may be attached to the surface, then take it out to dry, and crush the dried basalt ore with a pulverizer to a fineness of 1mm to obtain basalt ore powder;
[0041] 2) Mix the basalt ore powder obtained in step 1) with 0.1 kg of graphene oxide by ball milling for 2 hours, and discharge after mixing evenly to obtain the mixed powder;
[0042] 3) Add the mixed powder obtained in step 2) into the kiln, heat up to 1500°C, and stir at the same time to completely melt the basalt powder, and the modifier is evenly dispersed and suspended in the basalt melt to form a spinning melt;
[0043] 4) Drawing the spinning melt obtained in step 3) with a platinum-rhodium alloy drawing bushing with 800 holes and a temperature of 1300°C at a speed of 3000m / min to obtain basalt fiber precursors;
[0044] 5) The raw silk obtained in step 4) is unwound and twisted to form a complete continuous basalt fiber.
