Description
Technical Field
The invention belongs to the technical field of fishing pendants, and particularly relates to a preparation method of a disposable environment-friendly ceramic composite fishing pendant.
Background
Discarding the pendant, as the name implies, is the pendant ready for disposal. When fishing, a section of line which is thinner than the main line is connected below the main line, and then the weight is tied on the thin line, the thinner the section of line, the better the weight is, so that the weight can be driven continuously. If the weight is hung by an obstacle under water and pulls the main line, the hook, the rod and the like are protected from being lost as the pull line is thin and is broken once pulled. Generally, fishing is carried out at places with riprap at the water bottom or many stone seams of reservoir dams, and the pendants are easily clamped by the stone seams. If the weight is tied on the main line, the weight is likely to be pulled out by pulling the main line without pulling, and the main line is deformed by pulling, which affects the strength of the fishing line and makes it a broken line, and even more likely to break the main line, thus the loss is larger. If the throw-away sinker is used, the loss can be greatly reduced. It is also an empirical talk about the choice of fishing points in natural waters such as reservoirs. For example, chinese patent CN201610667483X discloses that the fish catch-up preventing abandon pendant can attract fish to gather and avoid eating in natural water cities such as reservoirs and rivers where there are riprap, branches and sundries on the water bottom. The water bottom of the Ma plain is not hung, but can be eaten without food, is not beneficial to concealment, and can not store fish, especially big fish. The mess of the water bottom brings trouble to the fisher for hooking, but the problem cannot be solved. The method of abandoning the pendant is adopted, fishhooks are directly sent into disordered objects, and hooks are hooked to hook the fishhooks, and the pendant is hung to hang the pendant. Although there is a fear of breakage of the hook, it is always better than the smooth fishing without any gain in balance. The dropping is just to use a small section of thin wire to tie the dropping independently, once the dropping is hung, the wire can be pulled off with a little force, and the main wire is protected by losing one lead drop. Therefore, the fishing proverb says: the fishing is messy and smooth, and the lead is usually suitable for fishing weight balance weight, usually a lead weight. This is because lead has a high density in metal, a large mass when it is small in volume, and good plasticity. Lead is a toxic metal and needs to be used properly. Enough lead weights are left in a water body within a certain small range, and when indexes such as pH value in water are changed, the lead weights are dissolved, so that the water quality is possibly threatened, and a preparation method capable of abandoning the environment-friendly ceramic composite material fishing weight is urgently needed to be developed by technical personnel in the field so as to meet the requirements of the existing application market and performance.

The metal ceramic has the advantages of metal and ceramic, and has the characteristics of high hardness, wear resistance, metal toughness, high thermal conductivity, good thermal stability, high temperature resistance, corrosion resistance, wear resistance and the like.
Further, the organic binder in the first step is a polyvinyl alcohol solution with a mass fraction of 20-25%, and the polyvinyl alcohol is polyvinyl alcohol with an average polymerization degree of 1650-1850 and an alcoholysis degree of 96-98.
Furthermore, the bonding metal accounts for 35-40% of the mass fraction of the paste.
Further, the heating and glue removing process buries the falling blank in the aluminum oxide powder forged at 1200-1300 ℃, the temperature is raised to 100 ℃, the heating rate is 50 ℃/h, the heat is preserved for 0.5-1 h, the heating rate is 100 ℃/h, the temperature is raised to 200-350 ℃, the heating rate is 35-40 ℃/h, the temperature is raised to 400 ℃, and the heat is preserved for 3-4 h when the temperature is 400 ℃.
The invention has the beneficial effects that:
the fishing weight made of the disposable environment-friendly ceramic composite material is metal ceramic, the non-homogeneous composite material is composed of ceramic and bonding metal, the ceramic and the bonding metal are ground and mixed uniformly, and the mixture is sintered in an inert atmosphere after being formed, so that the fishing weight made of the disposable environment-friendly ceramic composite material can be prepared. The invention adopts organic adhesive, which is changed from solid state to liquid state or gas state and discharged from the green body during calcination. The organic binder is melted, decomposed and volatilized in a large amount in the green body, so that the green body is deformed and cracked, and therefore, glue is required to be discharged, conditions are created for next firing, the green body obtains certain mechanical strength, and the reduction effect of the binder during firing is avoided. The alumina is calcined to ensure that the green body is heated uniformly, the discharge of the adhesive is uniform and consistent, and the deformation and cracking can be prevented.
Compared with the prior art, the invention has the following advantages:
the present invention relates to a fishing pendant made of composite material made up by using tungsten carbide and nickel alloy as raw material and using cobalt, nickel, tungsten and their alloys as main metal base body as adhesive. According to the weight percentage, the content of carbide is 45-88%, the density of tungsten carbide cermet is high, lead is a toxic metal and needs to be used properly, enough lead drops are left in a water body within a certain small range, when indexes such as the pH value in water are changed, the lead drops are dissolved, the water quality is possibly threatened, the lead drops are harder than lead and softer than lead in the aspect of hardness, a fishing group is dragged at the water bottom with stones, and when the fishing group slides at the water bottom, the lead drops made of lead are easy to scrape and dent. Because the material is softer, the knocking sound of lead at the water bottom is blunter, while the ceramic pendant sound of the invention is crisper, has particularly excellent wear resistance and corrosion resistance, has long flying distance and is more stable, and the probability of fish is naturally higher in winter.
