Abstract

The invention discloses an on-batch steel hot-galvanizing environment-friendly type multi-effect galvanization helping liquid and a use method thereof. Each liter of the on-batch steel hot galvanizing environment-friendly type multi-effect galvanization helping liquid comprises the following substances: a filming agent, an accelerant, a complexing agent, an anti-explosion zinc agent and water. The invention further provides the use method of the on-batch steel hot galvanizing environment-friendly type multi-effect galvanization helping liquid. The use method requires that the working temperature is 50-60 DEG C, the pH value is 3.5-5, and the galvanization time is 3-6 minutes, and a workpiece can be directly fed to a next zinc immersion procedure after galvanization helping without being dried, so that the time is saved, and the efficiency is improved. In addition to the capability of meeting the common requirements of an on-batch steel hot-galvanizing process, the on-batch steel hot-galvanizing environment-friendly type multi-effect galvanization helping liquid further has the characteristics that the energy consumption for heating the galvanization helping liquid is reduced due to adoption of intermediate temperature galvanization helping, the investment is reduced as no drying is needed after galvanization helping, and the energy consumption for drying is reduced; the increase of Fe<2+> in the galvanization helping liquid is effectively controlled, zinc ash and zinc slag are reduced in zinc immersion, no dust is generated, explosion is effectively avoided, and multiple effects that a galvanization helped film layer is uniform and free of galvanization omission, a zinc layer is bright, and the like, are achieved.

Description

technical field [0001] The invention relates to an environment-friendly multi-effect plating aid solution for hot-dip galvanizing in batches of iron and steel and a method for using the same. Background technique [0002] my country's steel output ranks first in the world for many years in a row, and the problem of metal anti-corrosion has been paid more and more attention. The requirements for corrosion-resistant protection of steel parts using hot-dip galvanizing technology are increasing. According to statistics, the annual loss of steel materials due to corrosion accounts for one-fifth of the total output in the world. Corrosion has caused serious damage to modern industry, not only causing serious direct losses, but also causing indirect losses that are difficult to estimate, and even endanger human life and property safety. [0003] Hot-dip galvanizing has been widely used as an effective method for steel to prevent atmospheric corrosion. Compared with other metal an...
