Tšebeliso: tlhahisong ea aluminium hydroxide. Bohlokoa: peo ea aluminium hydroxide e silakantsoe, e kopanye le tharollo ea aluminate. Setlolo se hlahisoang se koaheloa ka ho hlohlelletsa le ho phekoloa ka carbon dioxide. Ho arola aluminium hydroxide ho tsoa ho joala ba 'm'e. Aluminium hydroxide e hlatsuoa.
Tlhahiso ena e amana le tlhahiso ea aluminium hydroxide.
Mokhoa oa ho fumana hydroxide e ntle ea aluminium [1] eo ts'ebetso e etsoang ka mekhahlelo e 'meli. Mokhahlelong oa pele tharollo ea aluminate e thijoa ka hydrochloric acid, 'me hydroxide ea aluminium e qhalakantsoeng hantle e hlahisoang e sebelisoa e le ho bola ha peo ea tharollo ea aluminate e sa tlatsoang haholo mohatong oa bobeli.
Bothata ba mokhoa ona ke litšenyehelo tse phahameng tse bakoang ke ho se tlosoe ha alkali ea caustic ke asiti, ho bokellana ha litšila ka har'a litharollo, jj.
Haufi le tlhahiso ena ke mokhoa [2] oo ho ona bakeng sa tlhahiso ea aluminium hydroxide e ntle e sebelisoang e le peo ho sebelisoa aluminium hydroxide e phofshoana.
Bothata ba mokhoa ona ke tharollo ea wintopo e phahameng.
Sepheo sa popo ena ke phokotso ya ditjeo tsa yuniti ya eneji ka ho eketsa tlhahiso ya hydroxide e ntle ya aluminium.
Ho sebetsana le ditharollo tsa aluminate ka carbon dioxide, tshebetso ya carbonization e sebediswa haholo dimeleng tsa alumina tse sebetsang ka tsela ya ho sila. Tshebediso ya carbonization e ka fana ka hydroxide e ngata e tswang.
Boholo ba thollo ea aluminium hydroxide e fumanoeng ts'ebetsong ea carbonization bo itšetlehile haholo ka mocheso oa carbonization le sebopeho sa litharollo tsa aluminate (maikutlo a alkali le alumina).
Mokhoa o tsebahalang (Litšepe tse bobebe. 1937, No. 10, S. 8-15) tlhahiso ea hydroxide e ntle ea aluminium ka mokhoa oa carbonization, ho kenyeletsoa le ts'ebetso ea litharollo tsa aluminate tsa carbon dioxide ultracracker (mahloriso a 200 g/l) mochesong o tlase (30kaC).
Leha mokhoa ona o fana ka hydroxide e ntle ea aluminium e hlahisoang haholo, tšebeliso ea eona e batla e sa khonehe ka lebaka la mathata a tekheniki a hlahang mehatong ea ho qetela ea ts'ebetso: Lefapha la pula le ho hlatsoa.
Leha ho le jwalo, ha ho sebediswa mokgwa wa nizkokontsentrirovannye wa ho etsa hore carbonization e se sebetse hantle.
Boholo ba aluminium hydroxide bo fumanoeng tlas'a maemo ana, bo khetholloa ka sebopeho se sa lekanang le dikahare tse ngata tsa dikarolwana tse mahoashe.
Tlhahiso ena e na le hore mokhoeng oa tlhahiso ea hydroxide e ntle ea aluminium, e kenyeletsang ho sila peo ea aluminium hydroxide, ho e kopanya le tharollo ea aluminate, ho tsofala ha suspension e hlahisoang ka ho hlohlelletsa, ho arola hydroxide ea aluminium ho tsoa ho joala ba 'm'a le ho hlatsoa, pele ho arola hydroxide ea aluminium ho tsoa ho joala ba 'm'a lerōle la slurry ho phekoloa ka carbon dioxide.
Lithuto li bontšitse hore ha ho sebetsoa litharollo tsa carbon dioxide aluminate tse nang le bongata bo boholo ba lintho tse tiileng, boholo ba likaroloana bo batla bo tšoana.
Ha peo e sithabetseng e etsoa ka tharollo ea aluminate e sa tlatsoang haholo, 'me e tsofala, ho emisoa ho hlahang ka ho hlohlelletsa ho hlahisa bongata bo boholo ba hydroxide ea aluminium e hasantsoeng haholo. Leha ho le joalo, chai ea hydroxide e ntle ea aluminium ntle le ts'ebetso e eketsehileng ea ho emisoa e tlase 'me e itšetlehile ka bongata ba alkali ea caustic ka har'a tharollo: ha bongata ba alkali bo le holimo, tlhahiso e theoha.
Ha ho sebetsoa carbon dioxide, tlhahiso ea aluminium hydroxide e fana ka suspension ea pele le tlhahiso ea aluminium hydroxide e tšoana le ha ho sebetsoa suspension kamora ho pepesehela pele, leha ho le joalo, e eketsa boholo ba likaroloana tsa aluminium hydroxide haholo.
Mokhoa ona o ka sebelisoa ho sebelisoa lisebelisoa tse seng li ntse li le teng.
Mokhoa ona o khethoa ho latela theknoloji ea spechitelnoj.
Ho bapisa lintlha tse tsoang litekong tse ngata ho bontša hore ts'ebetso ea hydrate slurry e fumanoeng kamora ho pepesetsoa motsoako oa tharollo ea aluminate le peo e sitsitsoeng, carbon dioxide e lumella ho fumana aluminium hydroxide e ntle le ho netefatsa chai e ngata ea sehlahisoa.
