Isihlabathi sequartz esigezwe nge-asidi

I-quartz sand pickling kanye nenqubo yokukhetha inemininingwane

Ekukhetheni isihlabathi se-quartz esihlanjululwe kanye nesihlabathi se-quartz esihlanzekile, kunzima ukuhlangabezana nezidingo zezindlela ezivamile zokuzuza, ikakhulukazi ifilimu ye-iron oxide ebusweni besihlabathi se-quartz kanye nokungcola kwensimbi emifantwini.Ukuze kuthuthukiswe kangcono ikhwalithi kanye nesivuno sokuhlanzwa kwesihlabathi se-quartz, kuhlanganiswe nezici zesihlabathi se-quartz esingancibiliki ku-asidi futhi sincibilike kancane kusixazululo se-KOH, indlela yokukhishwa kwe-asidi isiphenduke indlela edingekayo yokwelapha isihlabathi se-quartz.

Ukwelashwa kwe-quartz sand pickling ukwelapha isihlabathi se-quartz nge-hydrochloric acid, i-sulfuric acid, i-oxalic acid noma i-hydrofluoric acid ukuncibilikisa insimbi.

Inqubo eyisisekelo ye-quartz sand pickling

I proportioning acid lotion

Amathani esihlabathi adinga ukwenziwa nge-7-9% oxalic acid, 1-3% hydrofluoric acid kanye nengxube yamanzi engu-90%;Idinga amathani angu-2-3.5 amanzi, uma amanzi evuselelwa kabusha, khona-ke kuphela amathani angu-0.1 amanzi adingekayo ukuhlanza ithani lesihlabathi, ekusebenzeni kokuhlanza isihlabathi, nakanjani kuzoletha iningi lesihlabathi phezulu;Ukwelashwa kwe-quartz sand pickling ukwelapha isihlabathi se-quartz nge-hydrochloric acid, i-sulfuric acid, i-oxalic acid noma i-hydrofluoric acid ukuncibilikisa insimbi.

Ⅱ Ingxube ye-Pickling

Isixazululo se-picling sijova ethangini lokuqoqa bese sengezwa ngokwengxenye yokuqukethwe kwe-hydrochloric acid cishe cishe u-5% wesisindo sesihlabathi ukuze kuqinisekiswe ukuthi isihlabathi se-quartz sicwiliswe kwisisombululo sokukha futhi okuqukethwe kwe-hydrochloric acid cishe ku-5% isisindo sesihlabathi.

Ⅲ Isihlabathi sequartz esigezwe nge-asidi
① Isikhathi sokuthi isihlabathi se-quartz sicwilise isixazululo se-picling ngokuvamile amahora angu-3-5, isidingo esikhethekile sokwandisa noma ukunciphisa isikhathi sokucwiliswa ngokwesikhumba esiphuzi sesihlabathi se-quartz, noma isixazululo sokukhetha nesihlabathi se-quartz singanyakaziswa isikhathi esithile. isikhathi, okulandelwa ukusetshenziswa kwemishini yokushisa ukushisa isixazululo ekushiseni okuthile, kunganciphisa isikhathi sokukhetha.

② Ukusetshenziswa kwe-oxalic acid kanye ne-alum eluhlaza njengokunciphisa i-ejenti yokwelashwa kungathuthukisa ukuncibilika kwensimbi, futhi, amanzi, i-oxalic acid, i-alum eluhlaza ngokuhambisana nengxenye yesisombululo ekushiseni okuthile, isihlabathi se-quartz nesixazululo ngokuhambisana. ngengxenye ethile yokuxuba, ukugqugquzela, ukwelashwa imizuzu embalwa, isisombululo siyahlungwa futhi siphathwe ngemva kokululama.

③ Ukwelashwa kwe-Hydrofluoric acid: Umphumela muhle lapho ukwelashwa kwe-hydrofluoric acid kusetshenziswa kuphela, kodwa ukugxila kuphezulu.Uma kwabelwana nge-sodium dithionite, ukugxila okuphansi kwe-hydrofluoric acid kungasetshenziswa.

Ukuhlushwa okuthile kwe-hydrochloric acid nesisombululo se-hydrofluoric acid kwaxutshwa ku-slurry yesihlabathi se-quartz ngesikhathi esifanayo ngokuya ngesilinganiso;Ingase futhi iphathwe ngesisombululo se-hydrochloric acid kuqala, igezwe bese iphathwa nge-hydrofluoric acid, iphathwe ngokushisa okuphezulu amahora angu-2-3, bese ihlungwa futhi ihlanzwe.

Qaphela:

Uma i-hydrofluoric acid isetshenziselwa ukucwilisa isihlabathi se-quartz, ukusabela kuba nzima kakhulu.Ngokungeziwe ekuhlakazweni kwensimbi emithonjeni ye-acidic, i-HF ingaphinda isabele ngequartz ngokwayo ukuze incibilikise i-SiO2 namanye ama-silicates ogqinsi oluthile phezulu.

Kodwa-ke, lokhu kuphumelela kakhulu ekuhlanzeni isihlabathi se-quartz nokuqeda insimbi nokunye ukungcola, ngakho-ke i-hydrofluoric acid ilungele ukukhishwa kwe-asidi ye-quartz.Kodwa-ke, i-HF inobuthi futhi igqwala kakhulu, ngakho-ke amanzi angcolile aphuma nge-asidi adinga ukwelashwa okukhethekile.

iv Ukubuyiswa kwe-Acid kanye nokususwa kwe-asidi

Hlanza isihlabathi se-quartz esihlanzwe nge-asidi ngamanzi izikhathi ezingu-2-3, bese unciphisa nge-0.05% -0.5% yesisombululo se-alkaline ye-sodium hydroxide (caustic soda), nesikhathi sokungathathi hlangothi cishe imizuzu engama-30-60, futhi uqinisekise ukuthi yonke i-quartz isihlabathi is neutralized endaweni.Lapho i-pH ifinyelela ku-alkaline, ungakhulula i-lye futhi uhlanza izikhathi ezingu-1-2 kuze kube yilapho i-pH ingathathi hlangothi.

Ⅴ Isihlabathi se-quartz esomile

Isihlabathi se-quartz kufanele sikhishwe emanzini ngemuva kokuhoxiswa kwe-asidi, bese isihlabathi se-quartz kufanele somiswe emishini yokomisa.

Ⅵ ukuhlola, ukukhetha umbala nokupakishwa, njll.

Lokhu okungenhla kuyinqubo eyisisekelo yokuqoqwa kwesihlabathi se-quartz kanye nenqubo yokwelashwa kwe-leaching, i-quartz sand ore inokusabalalisa okubanzi ezweni lakithi, ngakho-ke kukhona umehluko emvelweni wesihlabathi se-quartz, ekuhlanzweni kwesihlabathi se-quartz kudinga nezinkinga ezithile ezithile. ukuhlaziywa, ukuthuthukisa inqubo efanelekile yokuhlanza isihlabathi se-quartz.
