Acidum lotus quartz harenae

Quartz Arena Pickling et Pickling Processus Detailed

In selectio purificati quartz harenae et excelsum castitatem quartz harenae, difficile est in occursum requisitis conventional beneficiata modi, praesertim ferro cadmiae filim in superficies in harenae et ferrum impudicitia in superficies in harenae et ferrum impudicitia in superficies in harenae et ferrum impudicitia in rimas. Ut meliorem emendare qualis et cedat de quartz harenae purificationem, cum characteres de quartz harenae insolubilis in acidum et leviter solutum in Koh solution, acidum leaching arenam.

Quartz Arena Pickling curatio est tractare quartz harenae cum hydrochloric acidum, sulphuric acidum, oxalic acidum aut hydrofluoric acidum ad dissolvere ferrum.

Basic processus of Quartz Arena Pickling

Ego proportionem acidum Lotion

Tons harenae opus est fieri de 7-9% oxalic acidum, 1-3% hydrofluoric acidum et XC% aqua mixtisque; 2-3.5 talenta aqua requirit si aqua recycled, tunc tantum 0.1 tons aquae necesse est emundare ton harenae in harenae purgatio operationem, non aliter adducere potissimum harenae est; Quartz Arena Pickling curatio est tractare quartz harenae cum hydrochloric acidum, sulphuric acidum, oxalic acidum aut hydrofluoric acidum ad dissolvere ferrum.

Ⅱ Pickling misce

In pickling solutio infusum est in picturis cisternina et addidit secundum proportionem hydrochloric acidum contentus sicut circa V% de harenae pondus ut in Quartz harenae acidum contentus de V% de harenae pondus.

Ⅲ acidum-lotus quartz harenae
① tempus Quartz harenae inebriat in pickling solutio est plerumque 3-5 horis, in specifica opus ad augmentum et decrescit in bibula in tempore, sequitur quoddam in quadam calefacere, potest ad calefacere ad tempus, ut a calefacere ad calefacere ad tempus, ut ad redigendum est a tortor est ad calefacere.

② The use of oxalic acid and green alum as reducing agent pickling treatment can improve the solubility of iron, in turn, water, oxalic acid, green alum in accordance with the proportion of the solution at a certain temperature, quartz sand and solution in accordance with a certain proportion of mixing, stirring, treatment for a few minutes, the solution is filtered out and treated after recovery.

③ Hydrofluoric Acidum curatio: et effectus est bonum cum hydrofluoric acidum curatio est applicantur solum, sed concentration est altior. Cum participatur cum sodium Dithionite, minus concentrationes hydrofluoric acidum potest esse.

A cernens cenaculo hydrochloric acidum et hydrofluoric acidum solutio mixta in quartz harenae slurry simul secundum proportionem; Potest etiam tractari cum hydrochloric acidum solution primo, laverunt et tractata cum hydrofluoric acidum, tractata ad altum temperatus ad 2-3 horis, tum percolantur et purgari.

Nota:

Si hydrofluoric acidum adhibetur ad acid inebriat quartz harenae, in reactionem est magis complicated. Insuper et dissolutio ferrum in acidic media, HF potest etiam agere cum Vicus se ad dissolvere sio2 et alia ex quadam crassitudine super superficiem.

Sed hoc est efficacius ad Purgato superficies Quartz harenae et eliminating ferrum et alia immunditia pollutio, ita hydrofluoric acidum est bonum acidum leaching of quartz. Tamen, HF est toxicus et altus corrosi, ita acidum leaching wastewater necessitates specialis curatio.

IV acid convaluisset et deacidification

Intus stupam acidum-lavit quartz harenae cum aqua, 2-3 temporibus, tum corrumpere cum 0.05% -0.5% of sodium hydroxide (caustic nitri) alkaline solution, et neutralization est de 30-60 minutes, et curare, quod omnes Quartz harenae est neutralized in loco. Cum PH pervenit alkaline, vos can dimittere lye et intus stupam 1-2 temporibus usque ad PH est neutrum.

Ⅴ siccum quartz harenae

Et quartz harenae debet esse exhausta aquae post acid recessus et quartz harenae aruit in siccitate apparatu.

Ⅵ protegendo, color lectio et packaging, etc.

Quod supra est basic processus of quartz harenae pickling et leaching curatio processus, quartz harenae ore habet relative wide distribution in patria, sic sunt differentias in natura Quartz Quartz Arena Purificationi Processus.
