Method for manufacturing monofilaments for energy-saving and emission-reduction type ocean fishing gear

Abstract

Disclosed is a method for manufacturing monofilaments for an energy-saving and emission-reduction type ocean fishing gear. MMWPE resin, PP resin, auxiliaries, a stirrer, a filament separating machine, a filament collecting machine, a single screw extruder and a twice drafting electric heating drafting machine are adopted. The method is characterized in that the MMWPE resin, the PP resin and the white oil auxiliaries are mixed and stirred with the stirrer evenly to obtain MMWPE / PP blended aggregates; melt extrusion is conducted on the MMWPE / PP blended aggregates through the single screw extruder, cooling and pre-drafting are conducted on spun filaments obtained through melt extrusion through low-temperature water in a cooling water tank and a first drafting roller, heat drafting is conducted twice on pre-drafted filaments through a first drafting water bath, a second drafting roller, a second drafting water bath and a third drafting roller, and blended monofilament beams are rolled through the filament collecting machine using a torque motor; filament separation is conducted on the blended monofilament beams through the filament separating machine to obtain the monofilaments for the energy-saving and emission-reduction type ocean fishing gear.

Description

technical field [0001] The invention relates to a method for preparing monofilaments for pelagic fishing gear. Background technique [0002] Pelagic fishery is an important part of fishery and plays an important role in human development. In the field of pelagic fishery technology, people have always attached great importance to the breaking strength and nodular strength of the monofilament used in pelagic fishing gear, which is directly related to the energy consumption and durability of pelagic fishing gear. To reduce the energy consumption of pelagic fishing gear and improve the durability of pelagic fishing gear. With the development of pelagic fishery, more and more attention is paid to the energy saving and durability of pelagic fishing gear in this technical field. Technicians urgently need to innovate and produce new monofilament materials for pelagic fishing gear, so as to pass the breaking strength and nodule strength of the material. Improve the energy saving an...

Problems solved by technology

Existing monofilaments for ocean-going fishing tackle use a single ordinary high-density polyethylene as raw material, and are processed and produced by traditional melt-drawing technology, which makes the fracture strength and nodule strength of the prepared monofilament poor, resulting in the failure of ocean-going fishing gear made of monofilament. Therefore, the existing monofilament for pelagic fishing gear is difficult to meet the production needs of modern pelagic fishery. People urgently need energy-saving and consumption-reducing monofilament for pelagic fishing gear and its preparation method to produce monofilament for pelagic fishing gear. New materials, but there is no method for preparing monofilaments for energy-saving and consumption-reducing pelagic fishing gear using MMWPE resin and polypropylene resin (referred to as PP resin) as raw materials and using special wire drawing technology. Therefore, energy-saving and consumption-reducing pelagic fishing gear The solution to the problem of the monofilament preparation method has become a long-standing unresolved technical problem in this technical field.
