| XF-911 acid Mist Inhibitor & CorrosionMitigator is the newest acid mist inhibitor and corrosionmitigator fornoble metallic hydro chloride developed by the designinstitute of our company . 911 is able to reduce effectivelythe acid mist product from Pickling ,and speed up thepickling process by 20-30%,with a reduction on the acidconsumption by about 30%. So far, 911 has been licensedfor national invention patent (patent No.93103919.3),and is widely used in steel pipe production, galvanizingprocess, automobile industry . It has been proven tosave consideral energy , increase operating efficiency, to conserve acid , to decrease steel consumption ,to ameliorate production environment , to safe guardthe health of labours , and to prolong the maintenanceintervals on manufacturing equipment . Users of thisproduct commend highly of it . |
"911"Development & Working Mechanism:
For a pickling enterprise , the main task for picklingprocedure is to remove the rust or oxide skin from the surfaceof the iron & steel work piece , so as to expose theferrite part of the work piece for the processing in nextprocedure . The main reaction is as follows:
Hydrochloric acid FeO+2HCl=FeCl2+H2O Fe2O3+6HCl=2FeCl3+3H2O Fe2O4+8HCl=FeCl2+2FeCl3+4H2O Fe+2HCl=FeCl2+H2 Sulfuric acid FeO+H2SO4=FeSO4+H2O Fe2O3+3H2SO4=Fe2(SO4)3+3H2O Fe3O4+4H2SO4=FeSO4+Fe2(SO4)3+4H2O Fe+H2SO4=FeSO4+H2 |
We can see from the above reactions that during the removalof oxide
skin, in company with the reaction of ferrite dissolvedin acid, H2
is discharged and forms the acid mist , whichcauses large quantity
of acid wasted, and brings about severepollution in the
environment.911uses noble metal chlorideand lanthan metal chloride
as electro-load transfer agentso that during pickling H2 ion is all the timekept away from electron , thus fails to convert
to H2atom that generates H2 molecule bubble causingacid mist to overflow. Therefore add 911
into the picklingtank will completely overcome the hazard from acid
mist,and also save acid and steel consumption, so that
severepollution in the environment will be totally averted.
911 acid mist inhibitor &corrosion mitigator is developedby our
company specifically for pickling process . Upontest , under
50-80processcondition , when adding 0.5%911 into the pickling tank
,theacid mist overflowing from the pickling tank can reduceabout
85% pickling rate increasing by 20-30%, acid is savedby 30%. Steel
consumption reduced by 60%. Pickling qualityfor workpiece greatly
enhanced. Most obviously is that ferritecrystalline on the surface
of the work piece whitens up,and the black carbon silt on the
surface of workpiece becauseof previous pickling diminishes, so
that the solidity forgalvanizing layer and painting layer of the
workpiece improvesremarkably. After its use in pickling procedure
in steelmill , according to production statement statistics, forone
ton of steel material pickled, eight to ten kgs of acidcan be
saved, with consideration to the factors of powersaving and energy
saving, for each ton of steel pickled,10-20Yuan cost can be saved
for high efficiency and spendingreduction. Besides, with the use of
911 product, workshopenvironment gets better, acid mist inside
greatly minimized,contributing to the prolonged maintenance cycle
for equipmentand plant building.
