Description
Technical field
The present invention relates to a kind of dedicated fluxing agents of galvanizing flux containing aluminium, belong to steel material surface plating technic technical field.
Background technique
Helping plating is exactly to immerse the steel piece after pickling in the zinc ammonium chloride quickening liquid of certain ingredients again, in article surface
Form the process of one layer thin of zinc chloride ammonium salt film.It helps plating process to play the role of steel piece surface clean, removes pickling
The molysite or oxide for remaining in article surface after cleaning make steel piece when entering zinc bath with bigger surface-active.
Upper one layer of salt film is deposited on steel piece surface, steel piece can be prevented from plating pond is helped, and this is inherent for a period of time empty to zinc pot is entered
It is corroded in gas.Ammonium chloride when the steel piece for helping plating to cross immerses zinc liquid, in the quickening liquid salt film on steel piece surface
Ammonia and hydrogen chloride gas can be resolved at relatively high temperatures, and hydrogen chloride accounts for dominating to the erosion of steel matrix at this time, makes base steel
Body surface face cannot form oxide, keep the state of activation of steel matrix.Therefore contain in traditional galvanizing by dipping fluxing agent
The ammonium chloride of certain content.
Fluxing agent used in hot galvanizing is mostly zinc ammonium chloride at present, but high temperature zinc liquid table in order to prevent in actual production
Face and air catalytic oxidation, are generally added aluminium alloy in zinc liquid, and fine and close A1 is formed on zinc liquid surface2O3Oxidation film reduces zinc
The oxidation loss of liquid.Some producers are even more added a large amount of aluminium alloy, make in this way to improve the brightness on hot galvanizing piece surface
With aluminium alloy hot dip is used while composite assistant again, a large amount of harmful vapors are generated when being bound to cause hot dip, influence worker's
Operation and surrounding enviroment.Therefore, it urgently finds one kind and is not likely to produce a large amount of harmful vapors in use, do not influence worker
Operation and surrounding enviroment fluxing agent.
Summary of the invention
The technical problems to be solved by the present invention are: for traditional fluxing agent during hot dip, and in galvanizing flux containing aluminium
Aluminium generate the aluminium chloride that easily distils at a lower temperature, cause production scene to generate a large amount of harmful vapors, influence worker operation
And the problem of ambient enviroment, provide a kind of dedicated fluxing agent of galvanizing flux containing aluminium.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
The dedicated fluxing agent of a kind of galvanizing flux containing aluminium, it is characterised in that: be made of the raw material of following parts by weight: 15~20
Part plant ash extract filter residue, 3~5 parts of calcinings material, 3~5 parts of calcirm-fluoride, 2~4 parts of emulsifier op-10s, 0.4~0.6 part is spat
Temperature -60,80~100 parts of dopamine solutions, 30~40 parts of water；
It is specific the preparation method is as follows:
(1) extraction of plant ash extract filter residue: by crystallisation by cooling after plant ash and mixed in hydrochloric acid, filtering and concentration, then

Short fibre, then the gained short fibre of modified dacron is added after citric acid is mixed with cerous nitrate solution, it is centrifugated after reaction, then washed
Expect with being calcined after drying to get calcining；
(3) preparation of fluxing agent: by plant ash extract filter residue, calcirm-fluoride, emulsifier op-10, Tween-60, dopamine
After solution and water are uniformly mixed, calcining material is added, continues to discharge after being stirred filling.
The dopamine solution mass concentration is 2g/L.
Concentration condition described in step (1) are as follows: in Rotary Evaporators, in temperature be 80~85 DEG C, pressure be 0.06~
Under the conditions of 0.08MPa, 30~45min of concentrated by rotary evaporation.
Crystallisation by cooling condition described in step (1) are as follows: temperature is 2~4 DEG C, and the time is 3~5h.
Polyester fiber diameter described in step (2) is 1.0~1.4mm.
The preparation steps of activated yeast mixture described in step (2) are as follows: by active dry yeast, pour into and be preheated to 33~35 DEG C of temperature
In water, 25~30min of stir-activating.
Calcination condition described in step (2) are as follows: be warming up to 780~800 DEG C with 3~5 DEG C/min rate program, heat preservation calcining
After 2~4h, room temperature is cooled to the furnace.
The present invention is compared with other methods, and advantageous effects are:
(1) the invention firstly uses hydrochloric acid reacts with plant ash, and main component is potassium carbonate in plant ash, in addition also contains
After phosphorus, potassium carbonate and phosphorus containing components are reacted with hydrochloric acid, generates corresponding metal hydrochloride and metal phosphate and is dissolved in water,
It is concentrated after crystallisation by cooling, reduce water in solubility salt solubility and make its crystallization be precipitated, the metal hydrochloride of precipitation and
Phosphate is as principle active component in plant ash extract filter residue, in use, reactive aluminum in phosphate and fluxing agent,
Aluminum phosphate is generated, the molten boiling point of the aluminum phosphate of generation is higher for aluminium chloride, can be by aluminium chloride fixed packet in part in system
It covers, avoids aluminum chloride sublimation at a lower temperature and production scene is caused to have a large amount of harmful vapors；
(2) present invention utilizes alkali liquid corrosion polyester fiber, so that PET fiber surface is formed pit, then mix and send out with saccharomycete
Ferment makes saccharomycete fixed growth in polyester fiber pit, consumes citric acid followed by saccharomycete tricarboxylic acid cycle, makes solution
The cerium ion of middle complexing discharges, at the same the carbon dioxide that generates of saccharomycete aerobic respiration make in saccharomycete surrounding medium carbonate from
Sub- concentration is promoted, and is formed carbonic acid cerium crystal in conjunction with cerium ion, and adsorbed by the organic matter on saccharomycete surface, is washed to be fixed on
In synthetic fibre fiber pit, carbonic acid cerium crystal further long macro aggregate is avoided, then the other cerium oxide of ultrafine nanometer is made through calcining,
The effect for improving the current efficiency of electroplate liquid, while the filming performance for cooperating dopamine solution excellent, suppression can be played in fluxing agent
The generation of aluminium chloride processed, solves the problems, such as aluminum chloride sublimation from source.
