Isihlabathi se-quartz esihlanziwe nge-asidi
Inqubo yokuqoqa isihlabathi se-quartz kanye nokuqoqa ngokuningiliziwe
Ekukhetheni isihlabathi se-quartz esihlanziwe kanye nesihlabathi se-quartz esihlanzekile kakhulu, kunzima ukuhlangabezana nezidingo zezindlela zokuhlobisa ezivamile, ikakhulukazi ifilimu ye-iron oxide ebusweni besihlabathi se-quartz kanye nokungcola kwensimbi emifantwini. Ukuze kuthuthukiswe kangcono ikhwalithi kanye nokukhiqiza kokuhlanzwa kwesihlabathi se-quartz, kuhlanganiswe nezici zesihlabathi se-quartz esinganyibiliki ku-asidi futhi esincibilika kancane kusisombululo se-KOH, indlela yokukhipha i-acid isibe yindlela edingekayo yokwelapha isihlabathi se-quartz.
Ukwelashwa kokuqoqwa kwesihlabathi se-quartz ukwelapha isihlabathi se-quartz nge-hydrochloric acid, i-sulfuric acid, i-oxalic acid noma i-hydrofluoric acid ukuze kuncibilikiswe insimbi.
Inqubo eyisisekelo yokuqoqa isihlabathi se-quartz
I-lotion ye-asidi elinganiselayo
Amathani esihlabathi kudingeka enziwe nge-7-9% ye-oxalic acid, i-1-3% ye-hydrofluoric acid kanye nengxube yamanzi engu-90%; Kudinga amathani angu-2-3.5 amanzi, uma amanzi ephinde asetshenziswe, khona-ke kudingeka amathani angu-0.1 amanzi kuphela ukuhlanza ithani lesihlabathi, emsebenzini wokuhlanza isihlabathi, ngokuqinisekile kuzokhuphula iningi lesihlabathi; Ukwelashwa kokukhipha isihlabathi se-quartz ukwelapha isihlabathi se-quartz nge-hydrochloric acid, i-sulfuric acid, i-oxalic acid noma i-hydrofluoric acid ukuze kuncibilikiswe insimbi.
Ⅱ Ingxube yokupheka
Isixazululo sokugaya sifakwa ethangini lokugaya bese sengezwa ngokwesilinganiso sokuqukethwe kwe-hydrochloric acid cishe u-5% wesisindo sesihlabathi ukuqinisekisa ukuthi isihlabathi se-quartz sicwiliswe esixazululweni sokugaya kanti okuqukethwe kwe-hydrochloric acid cishe ku-5% wesisindo sesihlabathi.
Ⅲ Isihlabathi se-quartz esihlanzwe nge-asidi
① Isikhathi sokuba isihlabathi se-quartz sicwiliswe esixazululweni sokukhuhla ngokuvamile singamahora angu-3-5, isidingo esiqondile sokwandisa noma ukunciphisa isikhathi sokukhuhla ngokwesikhumba esiphuzi sesihlabathi se-quartz, noma isisombululo sokukhuhla nesihlabathi se-quartz kungavuselelwa isikhathi esithile, kulandelwe ukusetshenziswa kwemishini yokushisa ukushisa isisombululo ekushiseni izinga lokushisa elithile, kunganciphisa isikhathi sokukhuhla.
② Ukusetshenziswa kwe-oxalic acid kanye ne-green alum njengokwelashwa kokunciphisa i-ejenti yokukhipha kungathuthukisa ukuncibilika kwensimbi, bese kuthi, amanzi, i-oxalic acid, i-green alum ngokuhambisana nesilinganiso sesisombululo ekushiseni okuthile, isihlabathi se-quartz kanye nesisombululo ngokuhambisana nesilinganiso esithile sokuxuba, ukuxuba, ukwelashwa imizuzu embalwa, ikhambi liyahlungwa bese liphathwa ngemva kokululama.
③ Ukwelashwa nge-hydrofluoric acid: Umphumela uba muhle uma ukwelashwa nge-hydrofluoric acid kusetshenziswa yodwa, kodwa ukuhlushwa kuba kukhulu. Uma kusetshenziswa ne-sodium dithionite, ukuhlushwa okuphansi kwe-hydrofluoric acid kungasetshenziswa.
Iqoqo elithile le-hydrochloric acid kanye nesixazululo se-hydrofluoric acid kwaxutshwa ku-slurry yesihlabathi se-quartz ngesikhathi esifanayo ngokwesilinganiso; Ingaphathwa futhi ngesisombululo se-hydrochloric acid kuqala, igezwe bese iphathwa nge-hydrofluoric acid, iphathwe ekushiseni okuphezulu amahora angu-2-3, bese ihlungwa bese ihlanzwa.
Qaphela:
Uma i-hydrofluoric acid isetshenziswa ukucwilisa isihlabathi se-quartz nge-asidi, ukusabela kuba nzima kakhulu. Ngaphezu kokuncibilika kwensimbi ku-acid media, i-HF ingasabela ne-quartz ngokwayo ukuze incibilikise i-SiO2 nezinye izinto ezi-silicates zobukhulu obuthile ebusweni.
Kodwa-ke, lokhu kusebenza kangcono ekuhlanzeni ubuso besihlabathi se-quartz nokususa ukungcola kwensimbi nokunye, ngakho-ke i-hydrofluoric acid ilungele ukukhishwa kwe-quartz nge-asidi. Kodwa-ke, i-HF inobuthi futhi igqwala kakhulu, ngakho-ke amanzi amdaka akhishwa yi-asidi adinga ukwelashwa okukhethekile.
Ukubuyiselwa kwe-Iv Acid kanye nokususwa kwe-acid
Hlanza isihlabathi se-quartz esihlanzwe nge-asidi ngamanzi izikhathi ezingu-2-3, bese ususa i-asidi ngesisombululo se-alkaline esingu-0.05%-0.5% se-sodium hydroxide (caustic soda), bese isikhathi sokususa i-asidi singaba yimizuzu engama-30-60, futhi uqinisekise ukuthi sonke isihlabathi se-quartz sisusiwe endaweni yaso. Lapho i-pH ifinyelela ku-alkaline, ungakhulula i-lye bese ususa i-asidi izikhathi ezingu-1-2 kuze kube yilapho i-pH isusiwe.
Ⅴ Isihlabathi se-quartz esomile
Isihlabathi se-quartz kufanele sikhishwe amanzi ngemva kokukhipha i-asidi, bese isihlabathi se-quartz kufanele somiswe emishinini yokomisa.
Ⅵ ukuhlolwa, ukukhetha imibala kanye nokupakishwa, njll.
Lokhu okungenhla inqubo eyisisekelo yokucubungula isihlabathi se-quartz kanye nenqubo yokwelapha i-leaching, i-quartz sand ore isakazeke kabanzi ezweni lethu, ngakho-ke kunomehluko emvelweni wesihlabathi se-quartz, ekuhlanzweni kwesihlabathi se-quartz futhi kudingeka ukuhlaziywa kwezinkinga ezithile, ukuthuthukisa inqubo efanele yokuhlanza isihlabathi se-quartz.
