Description
Technical field
Apparatus processing technique field is fished for the invention belongs to fishery, and in particular to a kind of high-strength polyethylene twist net slice
Processing method.
Background technology
Due to the design feature of twist net slice, twist net slice strength depends primarily on the strength character of monofilament, for superelevation
Molecular weight polyethylene, the braided construction of superpower performance and high-strength utilization rate due to itself having, so that mesh sheet possesses Zhuo
Strength character more, however, due to however, due to the special process needed for superhigh molecular weight polyethylene fibers fabrication processes and
High production cost, expensive price seriously constrains its popularization, and fishery is big to the demand of high intensity mesh sheet, and requires valency
Lattice are cheap, it is necessary to use the high reinforcing fiber of cost performance as mesh sheet matrix material, high-strength polythene filament has price
The advantage such as the low, ratio of performance to price is high, compared with common polythene, with intensity is high, lightweight, wear-resisting, ageing-resistant and performance valency
Lattice than it is high the advantages of, therefore, be widely used to the fish production such as trawlnet, net cage and sea anchor rope field, achieve good make
With effect, but with fast developments such as deep-water net cage culture industry and tuna seines, to the intensity and combination property of twist net slice
Higher requirement is proposed, and China is less to relation technological researching, accordingly, it would be desirable to enter to the intensity for how strengthening twist net slice
Row further investigation.
The content of the invention
The purpose of the present invention is that there is provided a kind of processing side of high-strength polyethylene twist net slice the problem of being directed to existing
Method.
The present invention is achieved by the following technical solutions：A kind of processing method of high-strength polyethylene twist net slice, will
High-strength polyethylene twist net slice makes its length reach the 102-104% of product specification by mechanical stretching, then by rack with drawing
The mesh sheet stretched is shaped while being pushed into sizing kettle, and particular content is that after closing sizing kettle, nitrogen is passed through into sizing kettle,
Opposite side extracts air out, can stop until not oxygenous in detection sizing kettle；Then benzene vapor is passed through into sizing kettle, until
Stop when pressure reaches 300-320kPa in sizing kettle, be warming up to 114-118 DEG C, after being kept for 8 minutes, open air bleeding valve discharge kettle
Interior benzene vapour；Then mesh sheet is taken out, soaked 10-15 minutes in temperature is 10-15 DEG C of water, then by after above-mentioned one-step building
The stretching of high-strength polyethylene twist net slice its length is reached the 106-108% of product specification, then by after rack and stretching
Mesh sheet is shaped again, is passed through vapours, and it is 120-140kPa to make pressure in sizing kettle, and holding temperature in the kettle is 105-115
DEG C, after being kept for 2-3 minutes, discharge steam, you can complete；
The high-strength polyethylene twist net slice is woven by high-strength polythene filament, and number of share of stock is 36 strands；The poly- second of high intensity
Alkene monofilament raw material includes the raw material of following parts by weight：It is 80-85 parts of high-strength polyethylene, 8-14 parts of low density polyethylene (LDPE), compound strong
Change 3-6 parts of auxiliary agent.
As further improvement of these options, the tensile mechanical properties of the high-strength polythene filament are diameter
0.2mm, line density 34.5tex, ultimate strength 23.854N, elongation at break 16.64%, single line knot strength 13.854N, fracture are strong
Spend 7.25cN/dtex, knot strength 4.32cN/dtex.
As further improvement of these options, the temperature of the benzene vapor is 101-105 DEG C.
As further improvement of these options, the tolysulfonyl amino acid is N-p-tolysulfonyl glycine and right
Tosyl alanine.
As further improvement of these options, the complex intensifying auxiliary agent includes：3,5- dinitrobenzoic acid imidazoles
2-3 parts of cobalt, 1-2 parts of 4- bromobenzaldehyde semicarbazones, 0.2-0.8 parts of tolysulfonyl amino acid, fatty alcohol sulfate 1.3-1.8
Part, 1.4-2.2 parts of diethylaluminum ethoxide sulfonic acid sodium succinate, 0.4-1 parts of benzoic acid.
As further improvement of these options, the benzene vapor of the air bleeding valve discharge is cooled back with cooling tube to be stored up
Deposit.
The present invention has advantages below compared with prior art：By adding in high-strength polythene filament raw material in the present invention
Plus composite assistant, make it in the case where line density is increased slightly, tensile mechanical properties also improve, while to being woven into
Sizing is modified the mesh sheet one-off drawing and benzene vapor of type to mesh sheet for the first time, makes its space structure more complicated, molecule knot
Structure is closer, increases intensity；Mesh sheet succeeding stretch and the mode of vapours sizing coordinate, and reduce the relaxation shrinkage of mesh sheet, protect
The product quality of fishing net is demonstrate,proved, the ultimate strength compared to same specification mesh sheet adds 3.5% or so, and the scope of application is wider.
