Description
Technical Field
The invention belongs to the technical field of fishing weights, and particularly relates to a preparation method of a disposable environment-friendly ceramic composite fishing weight.
Background
Discarding the pendant, as the name suggests, is the pendant that is ready to be discarded. When fishing, a section of thread thinner than the main thread is connected below the main thread, and then the pendant is fastened on the fine thread, so that the thinner the section of thread is, the better the pendant can be driven, and the more the pendant is, the better the pendant can be driven. If the pendant is hung by an obstacle under water, the main line is pulled, and the pendant is broken when being pulled because the pendant is thin, so that the main line, the hook, the rod and the like are protected from being lost. In general, when fishing at places with a large number of stone seams in the water bottom or in a reservoir dam, the sinker is easily caught by the stone seams. If the weight is tied on the main line, the main line is tied, the main line is not pulled out, the weight is pulled out by the main line, the main line is deformed after the weight is pulled out, the strength of the fishing line is affected, the main line is broken, and the loss is larger. If a disposal catch is used, losses can be greatly reduced. This is also an experimented conversation of the choice of fishing points in natural waters such as reservoirs. For example, chinese patent CN201610667483X discloses that a large amount of underwater microorganisms are collected in the places with rubble, branches and sundries at the bottom of natural water cities such as reservoirs and rivers, and attract fishes to gather and avoid food in the long term. While the water bottom of Yi Pingchuan is not hooked and falling, but has no food, is unfavorable for concealing, and can not hold fish, especially large fish. Of course, the mess of the water bottom can cause the trouble of hooking the fishermen, but is not solved without a solution. The method of discarding the drop is adopted, the fishhook is directly sent into the mess, the hook of the hook house is hung, and the drop house is hung. Although the broken line is damaged, the balance is better than the flat line. The disposal pendant is characterized in that a small section of fine wire is used for independently tying the pendant, once the pendant is hung, the wire is pulled off with little force, and the main wire is kept by the loss of the lead pendant. So the fishing is called: it is reasonable that the fishing is not flat, and lead is generally suitable for the weight for fishing, namely the lead weight. This is because lead has a high density in metal, a small volume, a high mass and good plasticity. Lead is a toxic metal and needs to be properly used. When indexes such as pH value in water change, the lead drop is dissolved, so that the water quality is very likely to be threatened, and a preparation method capable of discarding the environment-friendly ceramic composite fishing drop is needed to be developed by a person skilled in the art so as to meet the existing application market and performance requirements.
