Preparation method of isosceles right triangle deep sea aquaculture protection net

Abstract

The invention provides a preparation method of an isosceles right triangle deep sea aquaculture protection net. The preparation method comprises the four steps of granule mixing, preparation of wires for a protection net, preparation of net pieces and preparation of the protection net. A phthalocyanine green G pigment, an anti-ultraviolet agent UV-327, a polyhexamethylene guanidine grafted modified polypropylene material, tetrakis [beta-(3, 5-di-tert-butyl-4-hydroxyphenyl) propionic acid] pentaerythritol ester, a fluorescent yellow pigment, white oil and polypropylene granules are used as raw materials, wire drawing is performed after uniform mixing and stirring, bright yellow wires for the protective net are obtained, then wire making is performed, a net piece is woven, and the protective net is prepared. And a protective net is further prepared to finally form the protective net for deep and far sea culture. According to the technical scheme, the strength, protection, pollution prevention, storm resistance, bite resistance and impact resistance of the product are improved, the color warning function is achieved, and consumption reduction and resistance reduction of deep and far sea culture production, healthy growth of cultured fishes and green development of the deep and far sea culture industry are promoted.

Description

technical field [0001] The invention belongs to the technical field of deep-sea aquaculture, and in particular relates to a preparation method of a deep-sea culture protective net with bright yellow color. Background technique [0002] Deep sea aquaculture is a brand-new technical field in my country, which is very important to my country's food security. The inner and outer sides of the deep-sea aquaculture facility frame are generally equipped with inner nets and protective nets. Among them, the nets assembled on the inner side of the deep-sea aquaculture facility frame are referred to as the deep-sea aquaculture inner net or the inner net, and the deep-sea aquaculture facility frame is equipped with nets on the outside. Referred to as deep sea aquaculture protective nets or protective nets. Deep-sea aquaculture facilities usually include multiple sides, and one side is sometimes divided into multiple isosceles right-angled triangle areas by diagonal braces. For this reas...

AI Technical Summary

Problems solved by technology

After the protective nets are used in the sea for a period of time, a large number of algae and other fouling organisms will adhere to the protective nets. Once the fouling organisms are seriously attached, the force on the protective nets will increase sharply, and the fouling attached to the protective nets will The organisms will continue to wear and tear with the protective net and the protective net, which will cause damage to the protective net

Once the protective net is damaged, on the one hand, large aquatic animals can enter the outer side of the inner net and directly bite and destroy the inner net; Accidents have seriously affected the safety of fish farmed in deep and open seas

[0006] However, in the prior art, the wires for protective nets are generally made of the same raw material, and the ordinary monofilaments produced are made by traditional wire drawing process

Ordinary monofilament has no anti-fouling function, and its comprehensive properties such as strength are also low, which seriously restricts the green development of deep-sea aquaculture.

At the same time, there are many problems in the preparation of traditional protective nets: (1) Generally, non-yellow twisted yarns are used for processing, and heat setting treatment is not carried out after weaving the nets, resulting in poor wear resistance, low knot fastness, and poor durability of traditional protective nets. Anti-bite and has no warning function; (2) The edge mesh of the traditional protective net is not hemmed, so the edge mesh often becomes loose and damaged, and sometimes it is hooked on the structural parts of the frame, further causing protection. The net is damaged; (3) The strength of the traditional protective net (that is, the protective net) is made of ordinary fiber, and the comprehensive performance is average, and it cannot resist the huge impact of large aquatic organisms or foreign objects on the protective net; (4) the traditional The protective nets are assembled with unequal distances between the force lines, resulting in uneven force on the force lines, and local force lines are prone to breakage and damage under the current; (5) The intersection of the horizontal force line and the vertical force line in traditional protective nets is not tied It is tightly fixed, and the problem of slipping and wear is prone to occur when the force is stressed; (6) when four isosceles right-angled triangle deep-sea breeding protective nets are required for deep-sea breeding facilities, each protective net is made separately, and its production Low efficiency, and a lot of waste of protective net materials and assembly time; (7) When two pieces of mesh in traditional protective nets are stitched together, slip knots are generally used for the net knots, and the distance between two adjacent slip knots is as high as 4 mesh lengths or more , in actual farming applications, the slipknots at the stitching joints are prone to slippage due to stress, and the stitching joints are easy to stab foreign wild fish (destroying fishery resources). The traditional protective net has low knot fastness, and the net The knot stability is poor; (8) The mesh wire used for stitching and splicing the two mesh pieces in the traditional protective net generally uses ordinary polyethylene mesh wire, which is prone to breakage in actual production and a series of problems

[0007] To sum up, the problems existing in the above-mentioned traditional protective nets have seriously restricted the development of the deep sea aquaculture industry, and have become an urgent problem that the current industry needs to solve urgently.

In addition, the actual environment and requirements faced by the field of deep-sea aquaculture technology are similar to those in the textile field, fishing gear field, freshwater aquaculture field, near-shore aquaculture field, deep-water cage field, ordinary net cage field, ordinary fence field, offshore aquaculture field, sports field, etc. field, special protection field, military and national defense and other technical fields are far apart, and the monofilament, wire, net and netting technology used in these fields can neither be used as a comparison technology in this field, nor can it provide reference for the solution to the above problems

Due to the very high technical difficulty and other reasons, there is currently no public report on the preparation method of an isosceles right-angled triangle deep-sea culture protective net.
