Problems solved by technology

Lead rusts easily - oxidizes
Lead is often gray, and the lead ash on the surface often sticks to the hands of fishermen, causing hidden dangers to the health of anglers, and the fish that fall has eaten a certain amount of lead ash, and the health of people who eat fish will also cause hidden dangers
[0003] Moreover, the specific gravity of lead is 11.343g / cm3, which has certain limitations, the hardness is only 1.5, and it is easy to deform and damage

Embodiment 1

[0033] 1. Mix. Mix high-purity tungsten 1.8um electrolytic Ni powder 2.60um reduced iron powder 3.80um in the proportion of 90%W+7%Ni+3%Fe, mix 50Kg of mixture, and mix it into a "V" type mixer for 16 hours of dry mixing (in-machine Add 100kg ball-milling rod) and the powder after mixing crosses 150 mesh sieves.

[0034] 2. Admixture (also known as molding agent). Use the ratio of 60% PW (paraffin) + 20% EVA (ethylene) + 20% SA (stearic acid) to weigh the forming agent. According to the process of adding 4 kg of forming agent to 100 kg of mixture, first raise the temperature of the high-speed mixer to 120 ℃. Then put 50kg of compound material and 2kg of forming agent into the machine and mix for 60 minutes, then raise the temperature to 320°C, mix for another 40 minutes, and cool down. After the material is discharged, the block material is crushed with a crusher.

[0035] 3. Granulation. Use a twin-screw extruder to put the irregular mixture into the equipment, set the t...

[0043] Product of the present invention

[0044] 1. Mix. High-purity tungsten 1.8um electrolytic Ni powder 2.60um reduced iron powder 3.80um according to the ratio of 95% W + 3.5% Ni + 1.5% Fe, mixed with 50Kg mixture, mixed in a "V" type mixer for 12 hours dry mixing (in-machine Add 150kg ball milling rod) and mix the powder and cross 200 mesh sieves.

[0045] 2. Admixture (also known as molding agent). Use the ratio of 60% PW (paraffin) + 20% EVA (ethylene) + 20% SA (stearic acid) to weigh the forming agent. According to the process of adding 4kg of forming agent to 100kg of mixture, first raise the temperature of the high-speed mixer to 125°C. Then put 50kg of mixed material and 2kg of forming agent into the machine and mix for 70 minutes, then raise the temperature to 300°C. Mix for another 60 minutes and cool down. After the material is discharged, the block material is crushed with a crusher.

Abstract

The invention relates to a fishing weight, in particular to an environment-friendly tungsten alloy fishing weight. The environment-friendly tungsten alloy fishing weight contains tungsten, nickel and ferrum and has the density being 14.8-18.5g / cm<3> and the hardness HRC being 18-35, wherein the specific mixture ratio of the tungsten to the nickel to the ferrum are that the tungsten is 60-97 percent, the nickel is 3.5-25 percent and the ferrum is 1.5-15 percent. The environment-friendly tungsten alloy fishing weight disclosed by the invention has the advantages of simple process steps, simpleness and convenience in implementation and operation, freeness of pollution to the environment and worth of advocacy; the density of the produced tungsten alloy fishing weight can be controlled according to the requirement; and the tungsten alloy fishing weight comprises main components such as the tungsten, the nickel and the ferrum or the tungsten, the nickel and copper.

Description

technical field [0001] The invention relates to a fishing weight, in particular to an environment-friendly tungsten alloy fishing weight. Background technique [0002] Fishing sinkers are consumables for fishing, including counterweights on the hook for sinking the bottom, counterweights placed in fake baits, and some are directly processed into fake fishing, such as lures. The fishing sinkers used in daily life are basically all lead sinkers. Lead is a toxic metal. It can produce lead vapor during the processing process, which will cause certain hidden dangers to the health of workers in the production process. dissolve. When people throw their fishing rods to rivers, lakes, seas, reservoirs, and ponds very chicly, when people enjoy leisure fishing by the competitive ponds and fish ponds. Little do they know that they are consciously or unconsciously polluting the poor clean water we have (accounting for only 11% of the world's average per capita level). Trees and grains...
