Problems solved by technology

[0002] At present, since France applied hot-dip galvanizing to industry in 1836, it has a history of more than 170 years. In the past 30 years, with the rapid development of cold-rolled strip steel, the hot-dip galvanizing industry has developed on a large scale. Hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing. It is an effective metal anti-corrosion method. It is mainly used on metal structure facilities in various industries. It is to immerse the derusted steel in molten zinc to make the steel Build a zinc layer attached to the surface to achieve anti-corrosion purposes. The traditional hot-dip galvanizing process has high energy consumption, poor thickness uniformity of the galvanized layer, corrosion resistance, surface hardness, wear resistance, and low adhesion. Insufficient, therefore, therefore, it is very necessary to develop a production process of galvanized iron wire that can solve the above-mentioned technical problems

Embodiment 1

[0025] First clean the surface of the iron wire with clean water, then pickle to remove the rust on the surface of the iron wire, then clean the iron wire with clean water and dry it in an oxygen-free atmosphere, set a Y-shaped scratch with a scratch depth of 0.3cm, and then immerse Put epoxy acrylate, silicon and zinc in the composite zinc solution with a mass ratio of 0.2:0.5:3. The temperature of the composite zinc solution is controlled at 500°C, and the immersion time is controlled at 2 minutes. After taking it out, place it in the air at a temperature of 80°C. Cool in air for 3 hours, then transfer to water at a temperature of 50°C for 5 hours, and passivate to obtain the target galvanized iron wire.

Embodiment 2

[0027] First clean the surface of the iron wire with clean water, then pickle to remove the rust on the surface of the iron wire, then clean the iron wire with clean water and dry it in an oxygen-free atmosphere, set Z-shaped scratches, the scratch depth is 0.1cm, and then immerse Put it into the composite zinc solution with the mass ratio of epoxy acrylate, silicon and zinc at 0.5:1:5. The temperature of the composite zinc solution is controlled at 800°C, and the immersion time is controlled at 1min. After taking it out, place it in the air at a temperature of 60°C. Cool in air for 2 hours, then transfer to water at 80°C for 10 hours, and passivate to obtain the target galvanized iron wire.

Embodiment 3

[0029] First clean the surface of the iron wire with clean water, then pickle to remove the rust on the surface of the iron wire, then clean the iron wire with clean water and dry it in an oxygen-free atmosphere, set Z-shaped scratches, the scratch depth is 0.2cm, and then immerse Into the composite zinc liquid with the mass ratio of epoxy acrylate, silicon and zinc of 0.3:1:5, the temperature of the composite zinc liquid is controlled at 700°C, the immersion time is controlled at 1.5min, and it is taken out and placed in a 70°C Cool in air for 2.5 hours, then transfer to water at 60°C for 8 hours, and passivate to obtain the target galvanized iron wire.

Abstract

The invention discloses a production process of a galvanized iron wire. The production process comprises the following steps: removing rust on the surface of the iron wire and setting a scratch to obtain a scratched iron wire for use; and immersing the scratched iron wire into a composite zinc liquid for hot galvanization, cooling and passivation to obtain the target galvanized iron wire, whereinthe composite zinc liquid is composed of epoxy acrylate, silicon and zinc. The method of scratching the surface of the iron wire is adopted to improve the adhesion, in combination with the special composite zinc liquid under specific process conditions, galvanization is carried out to obtain the galvanized iron wire which is firmly combined, high in uniformity and long in service life, the anti-corrosion layer is wear-resistant and corrosion-resistant, the construction cost is low, the economic efficiency is high, and the method is simple.
