Embodiment 1
[0016] A processing method for improving glass fiber conductivity, comprising the steps of:
[0017] (1) Melting: Put the glass fiber into the melting furnace and heat it up to 970°C for 3.5 hours, then raise the temperature of the melting furnace to 1540°C and add nano-scale silicon carbide and carbon black powder, which can improve the wear resistance and wear resistance of the glass fiber. Conductivity, keep the temperature for 12.5 hours, improve the dispersion of silicon carbide and carbon black in the liquid glass fiber, and then cool down to 1250°C to draw the glass fiber in the molten state to obtain processed glass fiber;
[0018] (2) Cooling: Heat the drawn glass fibers in cooling cabinets at 820°C, 530°C, and 310°C for 2.5 hours, and then cool them to room temperature with circulating cooling water to obtain cooled glass fibers;
[0019] (3) Activation treatment: first immerse the cooled glass fiber in the treatment liquid and seal it, then raise the temperature to ...
Embodiment 2
[0026] (1) Melting: put the glass fiber into the melting furnace and heat it up to 980°C for 4 hours, then raise the temperature of the melting furnace to 1570°C and add nano-scale silicon carbide and carbon black powder, which can improve the wear resistance and conductivity of the glass fiber Maintain the temperature for 13.5 hours to improve the dispersibility of silicon carbide and carbon black in the liquid glass fiber, and then lower the temperature to 1260°C to draw the glass fiber in the molten state to obtain processed glass fiber;
[0027] (2) Cooling: Insulate and cool the drawn glass fibers in cooling cabinets at 870°C, 560°C, and 380°C for 3 hours, and then use circulating cooling water to cool to room temperature to obtain cooled glass fibers;
[0028] (3) Activation treatment: first immerse the cooled glass fiber in the treatment liquid and seal it, then raise the temperature to 79°C and soak for 47 minutes, then pass the atomized acetic acid into the airtight ro...
