Embodiment Construction
[0006] The invention adopts a mixer, a twin-screw extruder, a single-screw extruder, a double-drawing electric heating drafting machine, a wire receiving machine using a torque motor, a spinning machine, and a spinning-grade dry high-density polyethylene (HDPE) Resin, nano-scale dry zinc oxide (ZnO) (if the nano-scale dry ZnO material is damp, it should be dried) and spinning turpentine additives, the invention will dry the spinning grade HDPE resin after sieving treatment (if If the HDPE resin is damp, it should be dried, dried in the sun or air-dried, etc.), nano-scale dry ZnO is mixed with turpentine additives for spinning, and the melt index of spinning-grade dry HDPE resin should meet 0.6g / 10min-1.5g / 10min; the average particle size of nanoscale dry ZnO is less than 40nm, and the addition amount is 4.6‰-5.2‰ of the weight of spinning-grade dry HDPE resin; the addition amount of turpentine additive for spinning is 0.3%- 0.4%; the mixture of spinning-grade dry HDPE resin, ...
