The invention adopts the modes of adding the glass fiber and the stiffening master batch and the like, improves the whole tensile strength and the bending stress of the pipeline, and ensures that the stiffening pipe has rigidity and flexibility in the oyster hanging process, thereby ensuring the breeding safety and good comprehensive benefit.
Description
Technical Field
The invention relates to a plastic pipeline technology, in particular to a high-density polyethylene stiffening pipe for oyster rows.
Background
At present, many oyster rows are built by adopting cedar and moso bamboo, the oyster rows are simple in structure and low in manufacturing cost, but the oyster rows exposed on a culture sea surface are easy to loosen and low in safety due to the fact that bamboo materials are not enough in strength, are easy to rot and break when being soaked in the sea and are weak in wind and wave resistance, and in addition, rotten bamboo is low in recycling value and easy to damage the environment due to untimely cleaning, and the oyster rows are not friendly to the environment. Therefore, the method has important significance for trying to improve the anti-wave capability and the comprehensive use benefit of the oyster row.
The high-density polyethylene material is a thermoplastic resin which has high crystallinity, is nontoxic, tasteless and semitransparent granular, has good heat resistance and cold resistance, good chemical stability, strong ageing resistance, no electrochemical corrosion and good corrosion resistance, and has excellent performance suitable for severe high-strength sunshine and corrosive environment at sea.
When the high-density polyethylene material is used for oyster rows, the flexibility and the rigidity are insufficient, the excellent elongation at break is suitable for the deep sea field with larger wind wave coefficient, but each adult oyster row is about 12 to 15 kilograms, and the oyster rows are bent in a creeping manner by the over-flexible material, so that the difficulty is brought to the harvesting and breeding of fresh oysters. The high-density polyethylene pipeline for oyster rows, which is hard in structure, safe, practical, energy-saving and environment-friendly, is developed in order to guarantee the breeding safety and good comprehensive benefits.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: overcomes the defects of the prior art and provides a high-density polyethylene stiffening tube for oyster rows.
In order to solve the technical problems, the invention adopts the technical scheme that: the utility model provides an oyster row increases just pipe with high density polyethylene, includes the body, the body is first PE layer, increases just layer and second PE layer from outside to inside in proper order, it is formed by polyethylene, glass fiber and increase just masterbatch, coupling agent mixture to increase just layer.
The rigidity-increasing master batch comprises, by weight, 50 parts of high-density polyethylene resin, 40 parts of micron-sized calcium carbonate particles, 2 parts of polyethylene wax, 3 parts of carbon black and 5 parts of tetraisopropyl di (dioctyl phosphite acyloxy) titanate.
The coupling agent is KH550.
The weight ratio of the polyethylene to the glass fiber to the stiffening master batch to the coupling agent is 70.
The surface of the first PE layer is provided with anti-skid patterns, the patterns are vertically distributed with the length direction of the pipeline, and the depth of the patterns is 0.5 mm.
The thickness of the second PE layer was 0.5 mm.
The surface of the reinforced layer is rough.
Further, the thickness of the stiffening layer is 4-5 mm.
The technical scheme adopted by the invention has the beneficial effects that: the high-density polyethylene rigidity-increasing pipe for the oyster row is simple in structure and reasonable in design, the pipe body is sequentially provided with the first PE layer, the rigidity-increasing layer and the second PE layer from outside to inside, the surface of the first PE layer is provided with the anti-skidding patterns, oyster hanging use is facilitated when fresh oysters are cultured, and oyster strings are not prone to moving and winding. The surface of the stiffening layer is in the shape of a rough PE pipeline, so that the connection strength between all layers of the pipe body is increased, and the modes of increasing glass fibers, stiffening master batches and the like are adopted, so that the integral tensile strength and bending stress of the pipeline are improved, and the stiffening pipe has stiffness and flexibility in the oyster hanging process, thereby ensuring the breeding safety and good comprehensive benefits.
