Processing method for antifouling melt spinning for far-reaching-sea net cage or floating-rope surrounding net

Abstract

The invention discloses a processing method for antifouling melt spinning for a far-reaching-sea net cage or a floating-rope surrounding net. The processing method is characterized by including the steps that UHMWPE powder, nanometer Cu powder, HDPE powder, silicone powder, antioxidant B225, assistant antioxidant DLTP, hydroxy stearic acid, nanoscale white carbon black, nanoscale kieselguhr, nanoscale aedelforsite, ethylene-vinyl acetate copolymer and turpentine assistant are weighed in the formula, then premixed to be poured into a high-speed kneading pot and subjected to high-speed kneading, and a blending-modification UHMWPE material is obtained; the blending-modification UHMWPE material is belted and extruded through a double-screw extruder, the extruded substance is metered through a metering pump additionally arranged through a double-screw outlet and belted and extruded through a spinneret hole, the extruded primary raw silk is cooled and pre-drafted, the pre-drafted silk is subjected to heat setting, then tows are winded through a silk winding machine of a torque motor, and are subjected to silk dividing through a silk dividing machine, and the antifouling melt spinning for the far-reaching-sea net cage or the floating-rope surrounding net is obtained.

Description

technical field

[0001] The invention relates to an antifouling melt-spinning yarn for the development and utilization of marine biological resources, in particular to an antifouling melt-spinning yarn for deep sea cages or floating rope seines. Background technique

[0002] In the technical field of marine biological resources development and utilization, the net cages produced in deep sea operations are called deep sea net cages; the breeding nets equipped with floating balls, ropes and nets and mainly used for breeding fish and other organisms are called deep sea net cages. It is a floating rope seine. In this field, people generally refer to the monofilament with anti-fouling function produced by the melt-spinning process as anti-fouling melt-spinning. Under the premise of the same rope net wire specification, the use of anti-fouling melt spinning (especially large-diameter anti-fouling melt spinning with a diameter of not less than 0.33mm) can effectively reduce fouling...
