Galvanized iron wire and white rusting agent compound for steel wire as well as method of making said galvanized iron wire and steel wire using said compound

Abstract

The present invention provides a composition of an anti-white rust agent for galvanized iron wire and steel wire and a method for preparing galvanized iron wire and steel wire by the anti-white rust agent, the composition can prevent the black and the white rust phenomena. The anti-white rust agent composition for anti-white rust agent is a depressor composition for preventing the white rust and the black phenomena on the surface of the molten galvanized iron wire and steel wire, the surface of the molten galvanized iron wire and steel wire forms coat layer in normal coating method, the characterized in that the composition has phosphoric acid and nitrite which the ratio of the three-valence chromium is 0.01%-0.5% and has one anti-white rust solution containing metal salt with titanium element.

Description

technical field [0001] The present invention relates to the manufacture method of galvanized iron wire and steel wire, more specifically, the present invention relates to the composition of galvanized iron wire and steel wire anti-white rust agent and the method for using this anti-white rust agent to manufacture galvanized iron wire and steel wire, in the manufacture of galvanized iron wire When used with steel wire, the proportion of trivalent chromium in the composition is minimized, which can prevent white rust from occurring during long-term storage of galvanized iron wire and steel wire. Background technique [0002] Generally, galvanized iron wires and steel wires are plated with an alloy layer (Fe+Zn) and a pure zinc layer (Zn) on the surface of the Fe layer. As the plating method, there are electrogalvanizing and hot-dip galvanizing. [0003] The electrogalvanizing method can adjust the current efficiency of the surface, and can adjust the roughness and luster of th...

AI Technical Summary

Problems solved by technology

[0005] However, the galvanized iron wire and steel wire produced by the above-mentioned hot-dip galvanizing method have blackened phenomenon within 5 hours during the salt spray test, and there is also a phenomenon of white rust in warehouse storage or transportation to the needy after the galvanized steel wire is produced. Shortcomings

In addition, there are also the following problems: white rust (corrosion phenomenon) occurs on the surface of the steel wire when the galvanized iron wire and steel wire are stored for a long time, and the galvanized layer is easily affected by moisture during storage and becomes discolored and corroded.
