A kind of preparation method of conical side net for semi-submersible culture platform

Abstract

The invention provides a method for preparing a truncated conical side net for a semi-submersible culture platform, which includes the preparation of antifouling monofilament bundles, the preparation of antifouling mesh sheets and the preparation of the truncated conical side net. Preparation raw materials include PP resin, dioctyl phthalate, polyethylene glycol fatty acid ester, cetyl phosphate, grafted polyguanidine salt / polyethylene pellets, surface-modified copper-nickel alloy nanoparticles; antifouling When preparing the mesh, the antifouling monofilament bundle is first twisted to obtain Z-twisted antifouling strands, and then three Z-twisted antifouling strands are processed into S-twisted antifouling twisted yarns, and then Process it into a double-knot mesh, and finally use 0.22 times the longitudinal breaking strength of the mesh as the pre-tension to heat-set the mesh; when preparing the frustum-shaped side mesh, follow the "single-knot-single-knot-double-knot-double-knot" cycle method Tie a knot, then cut the mesh in a fan ring, assemble the edge and mesh, and reinforce the edge; then butt and sew the busbar edges on the left and right sides of the fan ring mesh, and tie a double dead knot at an equal distance during the butt stitching.

Description

technical field [0001] The invention belongs to the technical field of aquaculture platforms, and in particular relates to a preparation method of a frustum-shaped side net for a semi-submersible aquaculture platform. Background technique [0002] The aquaculture platform is a special fish farming equipment that has just emerged in recent years. "Case body", "side net", "mesh", "edge", "net", and "semi-submersible aquaculture platform" are terms in the technical field of aquaculture platforms. The semi-submersible aquaculture platform generally refers to a cage platform that can realize a semi-submerged state in aquaculture. It generally consists of three parts: a frame system, a box system and an anchoring system. The box system (abbreviated as the box) refers to the space for raising aquatic animals composed of mesh sheets; the box generally includes two parts: side nets and bottom nets. The side net refers to the mesh that surrounds the perimeter of the box. Mesh refer...
