Embodiment Construction
[0006] The technical scheme of the present invention consists of a warning function yarn manufacturing process, a marking function yarn manufacturing process, a polyamide yarn manufacturing process, a ply yarn forming process and a ply forming outline process. Below take diameter φ 14.0mm, φ 18.0mm wire rope manufacture as example, illustrate the specific implementation of seawater net cage or fixed fishing gear with medium size different fiber mixed wire rope.
[0007] The manufacturing process of warning function yarn is as follows:
[0008]After sieving, dry HDPE 5000S resin (melt index should meet 0.6-1.5g / 10min, for example, choose melt index 0.9g / 10min; if HDPE 5000S resin is damp, it should be dried in an oven at 60-98°C for 30 minutes. ~80min or put it in the sun above 20℃ before use), dry T30S type PP resin (melt index is 2.1~3.9g / 10min; the amount added is 1.0~2.0% of the weight of HDPE 5000S resin; if PP If the resin is damp, it should be dried in an oven or under ...

Abstract
The invention relates to a method for manufacturing a net cage or different medium-sized fiber mixing steel cables for a set fishing gear, in particular to a method for manufacturing steel cables. The invention provides a method for manufacturing different fiber mixing steel cables for the fishing gear. The method adopts a stirring mill, HDPE resin, PP resin, luminous pigment, turpentine, pigment, an extruding machine, a drawing machine, a filament take-up machine, a filament dividing machine, a wire twisting machine and a rope manufacturing machine. The method is characterized in that the HDPE resin, the PP resin, the luminous pigment and the turpentine are stirred evenly and nascent filament devillicates extruded from the extruding machine are high-performance warning function monofilaments, and the monofilaments are twiddled into high-performance warning function yarn; the HDPE resin, the turpentine, the PP resin and the pigment are stirred evenly, high-performance marking functionmonofilaments are manufactured according to technology of filament drawing and filament dividing of the manufacturing technology of the warning function yarn, and the high-performance marking function monofilaments are twiddled into high-performance marking function yarn; polyamide multifilaments are used as substrate materials for manufacturing the yarn; and the sea water net cage or the different medium-sized fiber mixing steel cables for the set fishing gear are twiddled by adopting a structure of the 'SZS' twist direction.
Description
technical field [0001] The invention relates to a method for manufacturing medium-sized different-fiber mixed wire ropes for seawater cages or fixed fishing gear in the technical field of agricultural science and aquatic products. Background technique [0002] Wire is an essential material for seawater cages or fixed fishing gear in the aquatic industry, and its performance is directly related to the safety or fishing adaptability of seawater cages and fixed fishing gear. The cable base material for seawater cages or fixed fishing gear is mainly made of ordinary polyethylene monofilament. As a flexible structural material for seawater cages or fixed fishing gear, the breaking strength, elongation at break and its function are important indicators to measure its comprehensive performance. Most of the existing seawater net cages or fixed fishing gears are ordinary polyethylene wires, which have low breaking strength and have no warning mark function in dark environments. In ...
