Mokhoa oa ho khetha lehlabathe la quartz le mokhoa oa ho khetha o hlalositsoe ka botlalo
Ha ho khethoa lehlabathe la quartz le hloekisitsoeng le lehlabathe le phahameng la quartz, ho thata ho finyella litlhoko tsa mekhoa e tloaelehileng ea ho rua molemo, haholo-holo bakeng sa filimi ea tšepe ea oxide e holim'a lehlabathe la quartz le litšila tsa tšepe tse mapetsong.E le ho ntlafatsa boleng le lihlahisoa tsa tlhoekiso ea lehlabathe la quartz, ho kopantsoe le litšobotsi tsa lehlabathe la quartz le ke keng la qhibiliha ka acid le ho qhibiliha hanyenyane ka tharollo ea KOH, mokhoa oa leaching oa acid o fetohile mokhoa o hlokahalang oa ho phekola lehlabathe la quartz.
Kalafo ea ho kha lehlabathe la quartz ke ho alafa lehlabathe la quartz ka hydrochloric acid, sulfuric acid, oxalic acid kapa hydrofluoric acid ho qhala tšepe.
Mokhoa oa motheo oa ho khetha lehlabathe la quartz
Ke proportioning acid lotion
Lithane tsa lehlabathe li hloka ho etsoa ka 7-9% ea oxalic acid, 1-3% hydrofluoric acid le 90% motsoako oa metsi;E hloka lithane tse 2-3.5 tsa metsi, haeba metsi a sebelisoa hape, joale ho hlokahala lithane tse 0,1 feela tsa metsi ho hloekisa tonne ea lehlabathe, ts'ebetsong ea ho hloekisa lehlabathe, ho ke ke ha qojoa ho tlisa lehlabathe le leholo;Kalafo ea ho kha lehlabathe la quartz ke ho alafa lehlabathe la quartz ka hydrochloric acid, sulfuric acid, oxalic acid kapa hydrofluoric acid ho qhala tšepe.
Ⅱ Motsoako oa pickling
Tharollo ea pickling e kenngoa ka har'a tanka ea pickling 'me e eketsoa ho ea ka karolo ea hydrochloric acid content hoo e ka bang 5% ea boima ba lehlabathe ho netefatsa hore lehlabathe la quartz le kolobisitsoe ka har'a motsoako oa motsoako le hore hydrochloric acid e ka ba 5% ea boima ba lehlabathe.
Ⅲ Lehlabathe la quartz le hlatsoitsoeng ka asiti
① Nako ea hore lehlabathe la quartz le kolobise tharollo ka kakaretso ke lihora tse 3-5, tlhoko e khethehileng ea ho eketsa kapa ho fokotsa nako ea ho koloba ho latela letlalo le mosehla la lehlabathe la quartz, kapa tharollo ea mokelikeli le lehlabathe la quartz le ka hlohlelletsoa nako e itseng. ea nako, e lateloa ke tšebeliso ea lisebelisoa tsa ho futhumatsa ho futhumatsa tharollo ho mocheso o itseng, ho ka fokotsa nako ea pickling.
② Tšebeliso ea oxalic acid le alum e tala e le ho fokotsa phekolo ea likheo ho ka ntlafatsa ho qhibiliha ha tšepe, hape, metsi, oxalic acid, alum e tala ho latela karolo ea tharollo mocheso o itseng, lehlabathe la quartz le tharollo ho latela ka karolo e itseng ea ho kopanya, ho hlohlelletsa, phekolo ka metsotso e seng mekae, tharollo e hloekisoa ebe e phekoloa ka mor'a ho hlaphoheloa.
③ Kalafo ea Hydrofluoric acid: Phello e ntle ha phekolo ea hydrofluoric acid e sebelisoa e le mong, empa mahloriso a phahame.Ha e arolelanoa le sodium dithionite, metsoako e tlaase ea hydrofluoric acid e ka sebelisoa.
Motsoako o itseng oa hydrochloric acid le tharollo ea hydrofluoric acid e ne e kopantsoe le lehlabathe la quartz ka nako e le 'ngoe ho ea ka tekanyo;E ka boela ea phekoloa ka tharollo ea hydrochloric acid pele, e hlatsuoa ebe e phekoloa ka hydrofluoric acid, e tšoaroa ka mocheso o phahameng ka lihora tse 2-3, ebe e hloekisoa le ho hloekisoa.
Hlokomela:
Haeba hydrofluoric acid e sebelisoa ho etsa lehlabathe la quartz acid, karabelo e thata haholoanyane.Ntle le ho qhibiliha ha tšepe ka mecha ea litaba ea acidic, HF e ka boela ea itšoara ka quartz ka boeona ho qhaqha SiO2 le li-silicate tse ling tsa botenya bo itseng holim'a metsi.
Leha ho le joalo, sena se sebetsa haholo bakeng sa ho hloekisa bokaholimo ba lehlabathe la quartz le ho felisa tšepe le litšila tse ling, kahoo asiti ea hydrofluoric e molemo bakeng sa leaching ea acid ea quartz.Leha ho le joalo, HF e chefo ebile e senya haholo, kahoo metsi a litšila a nang le asiti a hloka phekolo e khethehileng.
iv Ho hlaphoheloa ha asiti le ho felisoa ha asiti
Hlatsoa lehlabathe la quartz le hlatsoitsoeng ka metsi ka makhetlo a 2-3, 'me u fokolise ka 0.05% -0.5% ea sodium hydroxide (caustic soda) tharollo ea alkaline,' me nako ea neutralization e ka bang metsotso e 30-60, 'me u netefatse hore quartz eohle. lehlabathe ha le nke lehlakore.Ha pH e fihla alkaline, o ka lokolla lye ebe o hlatsoa makhetlo a 1-2 ho fihlela pH e sa nke lehlakore.
Ⅴ Lehlabathe le omileng la quartz
Lehlabathe la quartz le lokela ho tšolloa ka metsi ka mor'a ho tlosoa ha acid, ebe lehlabathe la quartz le lokela ho omisoa ka thepa ea ho omisa.
Ⅵ tlhahlobo, khetho ea mebala le ho paka, joalo-joalo.
Ka holimo ke ts'ebetso ea mantlha ea ho khetha lehlabathe la quartz le ts'ebetso ea kalafo ea leaching, ore ea lehlabathe la quartz e na le kabo e pharaletseng naheng ea rona, ka hona ho na le phapang ea tlhaho ea lehlabathe la quartz, tlhoekiso ea lehlabathe la quartz le eona e hloka mathata a khethehileng. ho hlahloba, ho hlahisa mokhoa o loketseng oa ho hloekisa lehlabathe la quartz.
