Description
Technical field
The present invention relates to Industrial Metal phosphatization technical field of membrane, specially a kind of phosphating plant and preparation method thereof.
Background technology
Workpiece immerses phosphating solution, deposits to form the process that one layer of water insoluble crystal type phosphate changes film on surface,
Referred to as phosphatization.Phosphatization is to be applied to chemistry dress in conventional pretreatment technology, principle to change film process, is mainly used in steel table
Face phosphatization, non-ferrous metal pieces can also apply phosphatization.Phosphating process needs to carry out at a temperature of 50-75 DEG C, such free acidity
It is stable, easily grasp, phosphating time is short, production efficiency is high, and corrosion resistance and high temperature phosphorization film are essentially identical.Traditional phosphating pond is adopted
Heated with unilateral steam pipe, such efficiency of heating surface is relatively low and heats inequality.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of phosphating plant and preparation method thereof, to solve above-mentioned background skill
The problem of being proposed in art.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions,
A kind of phosphating plant, the phosphating plant includes phosphating pond and steam-heated pipe line,
The steam-heated pipe line is arranged in phosphating pond；The steam-heated pipe line is separately positioned on both sides in phosphating pond
Side wall on, and many steam-heated pipe lines are along side wall spaced set from top to bottom.
A kind of phosphating plant preparation method, it is characterised in that：Prepare in accordance with the following steps,
A) each composition proportion of lithium iron oxide for being adapted to metal fever compressive surface phosphating coat is prepared：Including iron oxide, hydroxide
Lithium；Phosphoric acid hydrogen ammonia；Carbon；
Its quality proportioning is：180：80：115：260：15, it is final to obtain lithium iron oxide block；
(b) that lithium iron oxide block is made into uniform powder is standby, by lithium iron oxide powder and phosphoric acid by mass
For 1:2 phosphating solution, the phosphating solution is put into by pending blank, and blank can obtain a kind of phosphating coat of Dark grey,
Heating dehydrogenation process is carried out to blank, the harm of hydrogen embrittlement is reduced, saponification process is carried out, further enhance extrusion billet and mould it
Between lubricate；
(c) the iron oxide lithium salts for being attached to matrix surface that the present invention is generated is one layer of salt film, and the composition is resistant to 1000
DEG C high temperature.
The beneficial effects of the present invention are：The invention has the advantages that, it is adaptable to ferrous metal hot extrusion, with fine
Corrosion resistance and stability, phosphating time is short, effect is good.
