Description
Technical field
The present invention relates to agricultural sciences aquatic products technical field seawater cage or stationary catching device with the different mixed with fibers rete cord of medium specification manufacture method.
Background technology
Rete cord is aquatic products field seawater cage or the requisite material of stationary catching device, and its performance is directly connected to the safety or the fishing adaptability of seawater cage, stationary catching device.Seawater cage or stationary catching device with the rete cord matrix material based on the common polythene monofilament.Rete cord is as seawater cage or stationary catching device flexible structure material, and disrumpent feelings brute force, elongation at break and function thereof are to weigh the important indicator of its combination property.Existing seawater cage or stationary catching device mostly are the common polythene rete cord with rete cord, and its disrumpent feelings brute force is lower, do not have the alarming sign function in dark surrounds.Aquatic products technical field rete cord can be divided into small dimension (4.0mm≤φ＜12.0mm, φ are the rete cord diameter, down with) rete cord, medium specification (rete cord of 12.0mm≤φ≤20.0mm) and the big specification (rete cord of φ＞20mm) by specification classification; By scope of application classification can be divided into net cage with rete cord, fishing gear with rete cord (comprising the stationary catching device head rope, the non-stationary catching device head rope); Can be divided into the pure mixing rete cord that spins rete cord, different mixed with fibers rete cord, fiber different shape of the same race by making the composition of guiding principle with fibrous material; Rete cord can be divided into polyethylene rete cord, polypropylene rete cord, polyamide rete cord and polyester rete cord by the raw material classification; Can be divided into 3 strands of rete cords, 4 strands of rete cords, 6 strands of rete cords and 8 strands of rete cords etc. by the number of share of stock classification.Because of seawater cage or stationary catching device member to knot tie up the location, once the key link is grasped, every thing falls in to place, main carrying lotus, night are arranged on function needs such as waters for a long time, make guiding principle with the selection of fibrous material and manufacture craft on seawater cage or stationary catching device should certain difference be arranged with other common rete cords in theory with rete cord.Existing seawater cage or stationary catching device are low or percentage elongation is little, manufacture craft is single because of brute force with rete cord, in use can cause lost network or fish to escape accident and take place because of intensity and the fracture of impact resistance difference generation rete cord; Existing seawater cage or stationary catching device rete cord are the pure mixing rete cord that spins rete cord or fiber different shape of the same race, it lacks alarm function, in use its can be because of not providing alarming sign to be crashed through or damage by passing ships in dark surrounds, causes lost network or fish to escape the accident generation and bring heavy losses.Because functional limitation's property of traditional seawater cage or stationary catching device rete cord, its security, impact resistance, alarm function exist defective, fishing relatively poor with adaptability, are difficult to satisfy be laid in night the special requirement in the water of aquatic products field seawater cage or stationary catching device facility.Seawater cage or stationary catching device are the important component parts in aquatic products field, the develop rapidly of modern aquatic products has proposed new demand to seawater cage or stationary catching device with the performance of rete cord, satisfy be laid in night the special requirement in the water of seawater cage or stationary catching device facility, reduce the operation consumption of traditional seawater cage or stationary catching device, improve safety, life cycle, wind and wave resistance fluidity energy and the economic benefit of seawater cage or stationary catching device, the sustainable sound development that promotes aquatic products industry is significant.Along with seawater cage or stationary catching device maximization, modernization and deepwater work are becomed privileged, need a large amount of powerful height, the different mixed with fibers rete cords of moderate, the flexible medium specification good, that have alarm function of elongation.But seawater cage or stationary catching device are still a long-term pendent difficult problem with the manufacturing of the different mixed with fibers rete cords of medium specification.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of seawater cage or stationary catching device with the different mixed with fibers rete cord of medium specification manufacture method.
