preparation example Construction

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

[0021] In the present invention, the above-mentioned cooling can be realized by existing conventional methods, as long as the cooling rate meets the requirements. For example, water cooling is possible.

[0022] The present invention has no special limitation on the conditions of hot-dip galvanizing, which can be conventional choices in this field. For example, the hot-dip galvanizing conditions may include: the temper...

Embodiment 1

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

[0035]The cast iron body was pickled and derusted with 5% by weight hydrochloric acid (at a temperature of 25° C. for 10 minutes), and then washed with water to remove acid. Then carry out flux treatment and drying, and the flux treatment is carried out with an aqueous solution of a composite agent consisting 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 at 580°C for 80s. The hot-dipped galvanized cast iron body was 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. Then passivation treatment was carried out on the above-mentioned fishing weight (at a temperature of 25° C. for 3 minutes) to obtain a lead-free fishing weight. Check the obtained fishing weights, the surface is clean...

Embodiment 2

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

[0038] The cast iron body was pickled and derusted with 5% by weight of hydrochloric acid (at a temperature of 10° C. for 15 minutes), followed by water washing for deacidification. Then perform flux treatment and drying, and the flux treatment is carried out with an aqueous solution of a composite agent consisting of 15% by weight of ammonium chloride and zinc chloride. The obtained cast iron body was brought into contact with molten zinc at 600°C for 60 s. The hot-dipped galvanized cast iron body was 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. Then passivation treatment was carried out on the above-mentioned fishing weight (at a temperature of 25° C. for 3 minutes) to obtain a lead-free fishing weight. Check the obtained fishing weights, the surface is clean and smooth, without zin...

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 ...
