Machining method for steel cable for deep and blue fishery

Abstract

The invention discloses a machining method for a steel cable for deep and blue fishery. The method is characterized in that UHMWPE powder, LLDPE powder, nanometer silver-loaded silicon dioxide antibacterial agent, white oil, silicone powder, hydroxystearic acid, antioxidant 1010, nanoscale kieselguhr, nanoscale wollastonite, antioxidant aid DLTP and ethylene-vinyl acetate copolymer are premixed and then poured into a high-speed kneading pot to be kneaded at a high speed, a UHMWPE composite material is melt and extruded through a twin-screw extruder, the extrudate passes through a metering pump additionally arranged on a twin-screw outlet to be melt and extruded from a spinning orifice, the extruded spun filament is cooled and predrawn, the predrawn filament is subjected to heat drawing, a filament rolling machine of a torque motor is used for rolling melt spinning beams after heat setting, a stranding machine is used for carrying out primary twisting on the melt spinning beam to obtain an S-twisted strand, and a three-strand twisting machine is used for processing three S-twisted strands into the Z-twisted three-strand steel cable for deep and blue fishery. The machining method can also be used in oceanographic engineering and trash holding engineering.

Description

technical field [0001] The invention relates to a cable in the technical field of development and utilization of polar and deep sea biological resources. Background technique [0002] Deep blue fishery refers to the development and utilization of polar and deep sea biological resources. In the deep blue fishery, the rope products made of twisted strands with a diameter greater than 4mm are called deep blue fishery ropes. Cable is one of the essential materials for deep blue fishery. Whether it is the development and utilization of polar krill resources, or the production activities such as deep-sea fish breeding cages and breeding nets, it is inseparable from cable. In the field, melt-spun monofilaments for processing steel wires are referred to as melt-spun filaments. In the prior art, melt-spinning yarns for wire and cable generally use a single high-density polyethylene resin (hereinafter referred to as HDPE resin) as a raw material, and are processed and produced by tr...

AI Technical Summary

Problems solved by technology

The comprehensive properties of the prior art wire rope and wire used for wire rope are relatively poor, and it is difficult to adapt to the development requirements of the deep blue fishery. It is urgently required to have good production safety, low price (lower than polyamide wire rope), excellent wear resistance, and high breaking strength. 、Functional high-performance dark blue fishery wire rope with certain antibacterial and antifouling effects
