Abstract

A novel hot-dip galvanizing flux and a method for using the same, comprising zinc chloride, potassium chloride, nickel fluoride, passivating agent, oxygen scavenger, complexing agent, coating flux controlling agent and water as components, Formulated as a plating flux; per 1L (liter) of the flux, the weight ratio of each component is as follows: zinc chloride 50-100g, potassium chloride 10-40g, nickel fluoride 5-30g, passivation agent 0.05 ‑0.50g, 0.5‑2.0g oxygen scavenger, 0.5‑1.0g complexing agent, 0.2‑1.0g coating film thickness control agent, and the rest is water; mix the above components to make a 1 liter solution to form a plating flux. The present invention achieves a good plating effect through the synergistic effect of each component of the plating flux and the process conditions; it does not need to be heated and dried in use, and the dosage is only less than half of that of zinc ammonium chloride flux, with less smoke, and solves the problem of The problem of super-thick galvanized layer is solved, the surface of galvanized layer is smooth and clean, no missing plating, low cost and good quality.

Description

technical field [0001] The present invention relates to a chemical additive and its use method, in particular to a hot-dip galvanizing flux and its use method, the hot-dip galvanizing flux and its method are mainly used in hot-dip galvanizing Zinc belongs to the technical field of hot-dip galvanizing of iron and steel materials. The present invention achieves a good plating effect through the synergistic effect of each component of the plating flux and the process conditions; it does not need to be heated and dried in use, and the dosage is only less than half of that of zinc ammonium chloride flux, with less smoke, and solves the problem of The problem of super-thick galvanized layer is solved, the surface of galvanized layer is smooth and clean, no missing plating, low cost and good quality. Background technique [0002] Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.11% by mass. In addition to carbon, steel also contains impurit...
