Example Embodiment

[0020] The present invention also provides a method for preparing a lead-free fishing sinker, which includes: contacting the cast iron body with molten zinc under the condition of hot-dip galvanizing, and cooling after the contact; the contact time The thickness of the obtained zinc layer is not less than 65 μm; wherein, the cooling includes: cooling the cast iron body after contacting with the zinc liquid at a rate of 5-8°C / s to 200±10°C, and then at a rate of 10-15°C / s The rate of s is cooled to room temperature (such as 15-35°C).

[0021] In the present invention, the above-mentioned cooling can be realized by an existing conventional method, as long as the cooling rate meets the requirements. For example, it can be water-cooled.

[0022] The present invention does not specifically limit the conditions of hot-dip galvanizing, which can be conventionally selected in the field. For example, the conditions of the hot-dip zinc may include: the temperature of the zinc liquid is 580...

Example Embodiment

[0033] Example 1

[0034] This embodiment is used to illustrate the lead-free fishing sinker provided by the present invention and its preparation method

[0035] The cast iron body was pickled to remove rust with 5% by weight hydrochloric acid (temperature at 25° C., time for 10 min), and then washed with water to remove acid. Then, the flux treatment is carried out and dried, and the flux treatment is carried out with an aqueous solution of a composite agent of 10% by weight of ammonium chloride and zinc chloride (temperature is 50°C, time is 20s). The obtained cast iron body was contacted with molten zinc liquid at 580°C for 80 seconds. The cast iron body after hot-dip galvanizing is water-cooled to 200°C at a rate of 6°C / s, and then water-cooled to room temperature (25°C) at a rate of 10°C / s. The fishing sinker after the above treatment is then passivated (temperature 25°C, time 3min) to obtain a lead-free fishing sinker. The fishing sinker will be inspected, and the appeara...

[0036] Example 2

[0037] This embodiment is used to illustrate the lead-free fishing sinker provided by the present invention and its preparation method

[0038] The cast iron body was washed with 5% by weight hydrochloric acid to remove rust (temperature 10°C, time 15min), and then washed with water to remove acid. Then, the flux treatment is carried out and dried, and the flux treatment is carried out using an aqueous solution of a composite agent of 15% by weight of ammonium chloride and zinc chloride. The cast iron body obtained was contacted with molten zinc liquid at 600°C for 60 seconds. The cast iron body after hot-dip galvanizing is water-cooled to 205°C at a rate of 8°C / s, and then water-cooled to room temperature at a rate of 12°C / s. The fishing sinker after the above treatment is then passivated (temperature 25°C, time 3min) to obtain a lead-free fishing sinker. The fishing sinker will be inspected, and the appearance is clean and smooth, free of zinc leakage, blist...

Abstract

The invention relates to the field of fishing plummets, and discloses a lead-free fishing plummet. The lead-free fishing plummet is characterized in that the fishing plummet comprises a cast iron body (1) and a zinc layer (2) attached to the surface of the cast iron body, and the thickness of the zinc layer (2) is not smaller than 65 micrometers. The lead-free fishing plummet fully solves the problem of environmental pollution brought by using lead plummets, has the advantages of being excellent in anti-corrosion and rust-proof performance, moderate in cost and superior in appearance grade.

Description

technical field [0001] The invention relates to the field of fishing weights, in particular to a lead-free fishing weight, a preparation method of the lead-free fishing weight and a lead-free fishing weight prepared by the method. Background technique [0002] Fishing pendants are an indispensable part of most fishing methods. At present, the main material of fishing pendants is lead, also known as lead pendants. Sometimes it is also made of lead-tin alloy, which has low hardness, is easy to cut and cut, and can adjust the weight at will to meet more water conditions. It has many styles, complete varieties and different weights, which are determined according to the characteristics of the water area. The shape, weight and other characteristics of the lead pendant will have a profound impact on fishing. When fishing, these factors must be considered to choose a suitable lead pendant. When fishing, when it is necessary to apply the lead skin, the state of the lead skin will ...
