Abstract

The invention discloses a preparation method of a wear-resistant trawl used in seawater. The preparation method comprises the following operating steps: (1), washing the surface of a woven trawl cleanly, putting into a soaking solution, and performing ultrasonic treatment for 20-30min, wherein the soaking solution is prepared from the following components in parts by weight: 17-22 parts of sodiumdibutyl sulfosuccinate, 10-15 parts of ammonium dithiocarbamate, 1-3 parts of phosphorylethanolamine and 290-320 parts of water; (2), then, brushing the surface of the trawl with a wear-resistant coating, and drying to obtain a finished product. The preparation method of the wear-resistant trawl used in the seawater, provided by the invention, can effectively improve the wear resistance of the trawl, improves the corrosion resistance thereof to a certain extent, and is especially suitable to be used in a submarine environment.

Description

technical field [0001] The invention belongs to the technical field of trawl preparation, and in particular relates to a method for preparing a wear-resistant trawl in seawater. Background technique [0002] Trawl is also called drag bucket. Trawling is the use of the movement of the ship to drag the fishing gear forward on the seabed or in the sea, forcing the fishing gear to pass through the fish, shrimps, crabs and other fishing objects in the waters into the net bag to achieve the purpose of fishing. The trawling operation is flexible, adaptable and has high production efficiency. Modern trawling gear can be used not only for fish, but also for cephalopods, shellfish and crustaceans; not only for fishing objects whose habitat water depth is only a few meters or tens of meters, but also for fishing objects whose habitat water depth reaches several meters. kilometers of deep-sea species. Trawl nets need to have excellent wear resistance, and the trawl nets made in the p...
