Plating assistant agent additive for preventing plating leakage of steel wire hot galvanizing

Abstract

The invention discloses a plating assistant agent additive for preventing plating leakage of steel wire hot galvanizing which comprises the following components in percentage by weight: 20-25% of fatty alcohol-polyoxyethylene ether, 20-26% of dodecyl phenyl polyoxyethyleneether, 8-14% of polyoxyethylene octylphenol ether, 3-6% of triethanolamine, 0.8-1.5% of carbamide and 30-36% of methyl alcohol. The method comprises the following steps: weighing the raw materials according to the proportioning of the additive, mixing and stirring the raw materials evenly to form the additive of the invention, adding the stock solution of the plating assistant agent additive of the invention into a slot according to a proportion that the amount of the added stock solution of the plating assistant agent additive accounts for 0.1-0.2% of the plating assistant agent bath solution, stirring evenly, and being able to use at the temperature of 70-75 DEG C. By adding the additive of the invention into the plating assistant agent, the wettability and the infiltrative of the plating assistant agent can be effectively enhanced, the plating effect on the surface of the steel wire is improved, and the plating leakage of the steel wire zinc plating is avoided.

Description

1. Technical field: [0001] The invention relates to a technology for preventing steel wire hot-dip galvanized galvanized layer from missing plating in the metal product industry, in particular to a plating flux additive for preventing steel wire hot-dip galvanized galvanized layer from missing plating. 2. Background technology: [0002] Hot-dip galvanizing is a surface treatment method commonly used for metal products. It is an anti-corrosion method that uses the low melting point of metal zinc to adhere to the surface of high melting point steel. The main purpose of hot-dip galvanizing of metal products is anti-corrosion rather than decoration. Partial iron leakage on the surface of metal products in hot-dip galvanizing technology is also called missing plating. This is an unacceptable galvanized layer specified in all standards. defect. Due to the excellent corrosion resistance of the hot-dip galvanized layer, the service life in the atmospheric environment can generally ...

AI Technical Summary

Problems solved by technology

Before the steel wire is hot-dip galvanized, although its surface has been degreased, degreased, pickled and derusted, there are still trace impurities on the surface of the steel wire attached to the surface of the steel wire. Due to the high surface tension of the commonly used plating flux solvent, it cannot be well The surface of the steel wire is wetted, and the flux solvent cannot play a role in the activation of the flux.

Therefore, after the steel wire enters the zinc pot, the metal zinc liquid cannot be in good contact with the surface of the steel wire, and thus cannot perform physical effects such as penetration and diffusion well, and it is prone to missing plating, which is the main problem that has plagued hot-dip galvanizing companies for a long time. question
