Tataiso ea Tlhokomelo ea Letsatsi le Letsatsi ea Boehmite

Boehmite, aluminium ea bohlokoa{{0}e thehiloeng ho lirafshoa, e sebelisoa haholo ho litšehetso tsa li-catalyst, likoti tsa lithium battery separator, le lirafshoa tse tsoetseng pele ka lebaka la bohloeki ba eona bo phahameng, botsitso bo botle ba mocheso, le ho se sebetse ha lik'hemik'hale. Leha ho le joalo, ho hloka tlhokomelo e nepahetseng nakong ea tšebeliso le polokelo ho ka lebisa ho senyeha ha ts'ebetso kapa ho senyeha ha moralo. Ka hona, ho tseba mekhoa ea tlhokomelo ea letsatsi le letsatsi ea saense ho bohlokoa.

Ntlha ea pele, taolo ea tikoloho ke motheo oa tlhokomelo ea boehmite. Boehmite e lokela ho bolokoa sebakeng se omeletseng, se nang le moea o motlakase 'me u qobe ho kopana ka ho toba le mongobo. Ho monyela ha mongobo ho ka eketsa lihlopha tsa hydroxyl, ho ama ts'ebetso ea ts'ebetso lits'ebetsong tse latelang. Ho khothaletsoa hore boehmite e koaloe sebakeng se sa tsitsang (joalo ka naetrojene) kapa e bolokoe ka har'a mongobo-e kentsoeng ka har'a mongobo joalo ka mekotla ea foil ea aluminium kapa linkho tsa vacuum. Ho feta moo, e lokela ho bolokoa hole le li-acid tse matla, li-bases tse matla, le li-solvents tsa organic ho thibela ho bola ha lik'hemik'hale kapa ho fetoha ha bokaholimo.

Ea bobeli, ho hloekisa le ho hlokomela ho hloka hore motho a be hlokolosi. Haeba bokaholimo ba boehmite bo silafalitsoe ke lerōle kapa tšilafalo e nyane, ka bonolo e hlakole ka anhydrous ethanol kapa joala ba isopropyl. Qoba ho sebelisa metsi kapa li-detergent tse nang le metsi ho thibela hydrolysis. Bakeng sa matheba a manganga, ho hloekisa ka ultrasonic ho ka etsoa tlas'a maemo a laboratori, empa nako le mofuta oa solvent li tlameha ho laoloa ka thata ho thibela tšenyo ea mohaho oa thepa. Ka mor'a phekolo, etsa bonnete ba ho omisa ka ho feletseng ho qoba mokelikeli o setseng o ka amang ts'ebetso.

Ho feta moo, mekhoa ea ho sebetsana le eona e ama ka ho toba nako ea bophelo ea boehmite. Ha u tšoara phofo ea boehmite, ho kgothaletswa ho roala liatlana le mask ho thibela tšilafalo ho tsoa mofufutso oa letsoho kapa oli le ho fokotsa kotsi ea ho hema lerōle. Sebelisa lisebelisoa tse khethehileng (tse kang polasetiki kapa likhaba tsa ceramic) ho fetisetsa thepa ho qoba ho hlahisa litšila tse tsoang lijana tsa tšepe. Haeba e sebelisoa ho-mocheso o phahameng (joaloka sintering), eketsa mocheso butle-butle ho qoba ho peperana ho bakoang ke khatello ea mocheso.

Qetellong, tlhahlobo ea kamehla ke senotlolo sa ho netefatsa tlhokomelo e sebetsang. Boehmite e bolokiloeng e lokela ho hlahlojoa khafetsa bakeng sa clumping, discoloration, kapa monko. Haeba ho na le mefokolo leha e le efe e hlokometsoeng, e lokela ho hlahlojoa ho netefatsa hore e ntse e finyella litlhoko tsa tšebeliso. Bakeng sa boehmite e seng e sa sebelisoe nako e telele, kalafo ea ho e busetsa hape (e kang-mocheso o phahameng) e khothaletsoa ho khutlisetsa thepa ea eona ea mantlha.

Ka tsamaiso ea saense ea tikoloho, mekhoa e bonolo ea ho hloekisa, mekhoa e tloaelehileng ea ts'ebetso, le ho hlahloba maemo a tloaelehileng, nako ea bophelo ea boehmite e ka atolosoa ka katleho, ho netefatsa botsitso le katleho ea eona lits'ebetsong tsa indasteri.
