Abstract
The invention relates to a hot-dip galvanizing plating auxiliary agent, wherein the plating auxiliary agent is composed of a mixed water solution containing aluminum chloride, zinc chloride, potassium chloride and sodium fluoride according to the proportion ratio of 30-40 g/L of the aluminum chloride, 30-35 g/L of the zinc chloride, 20-30 g/L of the potassium chloride, 5-10 g/L of the sodium fluoride and 2-10 g/L of sodium bicarbonate. The plating auxiliary agent is free of ammonium chloride so that the plating auxiliary agent is free from generating smog and can effectively improve the plating assistant effect on surface of steel wires. The plating auxiliary agent can prevent secondary oxidization of the surface of steel wires in air after plating assistance and can increase the plating layer quality of the surface of steel wires. The solution is easy to prepare and enables the plated layer on the surface of steel wires to be compact and smooth, free of pores and excellent in corrosion resistance.
Description
Technical field
The invention belongs to steel material surface coating technology field, specifically, is a kind of Plating Auxiliary of Hot Dip Galvanizing.
Background technology
Help plating operation to be the operation must carried out after steel wire pickling, the effect of plating assistant agent has two aspects: 1, play clean effect to Steel Wire Surface, remains in molysite or the oxide compound of Steel Wire Surface after removing pickling; 2, steel wire is made to have larger surfactivity when entering molten zinc.
Existing plating assistant agent generally adopts ammonium chloride and zinc chloride mixing solutions, because ammonium chloride is xln, easily come off from Steel Wire Surface after crystallization and cause leakage zinc, and the ammonia of ammonium chloride decomposes and hydrogenchloride meet cold chemical combination again, make to form too much smog during pot galvanize.
By retrieval, find following patent publication us related with the present patent application, publication number is CN101122000, the document discloses a kind of phytate plating resisting agent for heat zinc coating, it contains following weight percent composition: PHYTIC ACID ZINC SALT 8%-12%, borax 2%-6%, Sodium Fluoride 13%-17%, citric acid 2%-7%.Oxalic acid 35%-25%, hydrochloric acid callosity 40%-33%.During with the pot galvanize of phytate plating assistant agent: pre-plating piece pickling, rust cleaning after washing; By the solid phytic acid salt plating assistant agent thin up of above composition, its proportioning is phytate plating assistant agent: water=1: 2.5-4, puts into pond; Pre-plating piece soaks 50-60 second in pond, and working temperature is 40-50 DEG C; Pre-plating piece temperature is 35 DEG C-40 DEG C; In indoor placement seasoning in 10-20 minute.
By contrast, above-mentioned patent publication us and present patent application have relatively big difference in technical scheme.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and prevent plating leakage and smog is many, the Plating Auxiliary of Hot Dip Galvanizing of not containing ammonium chloride.
The solution of the present invention is achieved in that
A kind of plating assistant agent for galvanizing, this helps plating liquor to be made up of the mixed aqueous solution of aluminum chloride, zinc chloride, Repone K, Sodium Fluoride, and its proportioning is: aluminum chloride 30-40g/L, zinc chloride 30-35g/L, Repone K 20-30g/L, Sodium Fluoride 5-10g/L, sodium bicarbonate 2-10g/L.
And described aluminum chloride is 40g/L, zinc chloride 35g/L, Repone K 18g/L, Sodium Fluoride 5g/L, sodium bicarbonate 2g/L.
And concentration of aluminum chloride is 30g/L, zinc oxide concentration is 30g/L, potassium chloride concentration is 30g/L, concentration of sodium fluoride is 7g/L and sodium bicarbonate 3g/L.
And described aluminum chloride is 38g/L, zinc chloride 30g/L, Repone K 22g/L, Sodium Fluoride 5g/L, sodium bicarbonate 5g/L.
Advantage of the present invention and positively effect are:
Not containing ammonium chloride in this plating assistant agent, therefore can not produce smog, and effectively improve Steel Wire Surface help plating effect, after preventing helping plating, Steel Wire Surface is in atmosphere by secondary oxidation, improves the quality of coating of Steel Wire Surface.Solvent of the present invention preparation is simple, such that hot-dip galvanizing steel wire overlay coating is fine and close, smooth, pore-free, corrosion resistance and good.
