Malebela a Tšebeliso ea Boehmite

Boehmite, aluminiamo ea bohlokoa{{0}e thehiloeng ho liminerale, e sebelisoa haholo ho litšehetso tsa li-catalyst, likoti tse arolang libeteri, le lisebelisoa tsa ceramic ka lebaka la sebaka sa eona se phahameng, ho tsitsisa ha mocheso o matla, le ho se sebetse ha lik'hemik'hale. Leha ho le joalo, ts'ebetso ea eona e felletseng e itšetlehile ka mekhoa e nepahetseng ea tšebeliso. Lintlha tse latelang li tšohla lintlha tsa bohlokoa mabapi le phekolo ea pele, ho hasana, le taolo ea tikoloho ea tšebeliso.

1. Phekolo ea Pele le Taolo ea Bohloeki

Lisebelisoa tse tala tsa Boehmite li ka ba le litšila kapa mongobo 'me li hloka tlhoekiso ho latela litlhoko tsa kopo pele li sebelisoa. Ka mohlala, ka har'a lithium battery separator coatings,{1}}purity boehmite e holimo (joalo ka phase) e ka ntlafatsa mocheso oa mocheso, ha lisampole tse tlase- tsa bohloeki li ka hlahisa litšila, tsa ama ts'ebetso ea betri. Industrial-grade boehmite e ka ba asiti-e hlatsuoa kapa ea hlatsuoa ho tlosa litšila tse kang tšepe le silicon. Bakeng sa laboratori-boemo ba boehmite, XRD kapa tlhahlobo ea BET e khothaletsoa ho netefatsa hore sebopeho sa kristale le bokaholimo li fihlela litlhoko.

2. Phatlalatso Theknoloji Optimization

Likaroloana tsa Boehmite li na le tšekamelo ea ho kopana, kahoo ho hasana ha junifomo ho bohlokoa ka ho khetheha nakong ea ho lokisetsa slurry. Bakeng sa lits'ebetso tsa metsi{{1}, ho khothaletsoa ho sebelisa li-dispersants tse kang sodium hexametaphosphate kapa ammonium polyacrylate, le ho arola li-aggregates ka ultrasonic treatment (power 200-400W, nako metsotso e 5-10). Bakeng sa litsamaiso tse thehiloeng ho oli, li-organic modifiers (joalo ka li-silane coupling agents) li ka sebelisoa ho ntlafatsa hydrophobicity. Ka mor'a ho hasana, kabo ea boholo ba likaroloana e lokela ho behoa leihlo ho sebelisoa laser particle size analyzer, hangata e lebisang mefuta e mengata ea 50-200 nm ho netefatsa ts'ebeliso e nepahetseng.

3. Tšebelisano ea Tikoloho ea Kopo

Ho tsitsa ha mocheso oa Boehmite ho etsa hore e tšoanelehe-mocheso o phahameng (joalo ka ceramic sintering ka holimo ho 500℃), empa ho senyeha ha ts'ebetso ka lebaka la ho monya mongobo ho tlameha ho qojoa libakeng tse tlase{2}}mocheso. Ka mohlala, tšimong ea ts'ehetso ea li-catalyst, ha boehmite e jere li-nanoparticles tsa tšepe, mocheso oa calcination o tlameha ho laoloa pakeng tsa 400-600℃ho qoba liphetoho tsa mohato (tse kang ho fetolela ho -Al₂O₃). Ka indasteri ea ho roala, ho eketsoa ha silika e nyane ho khothalletsoa ho ntlafatsa sebopeho sa filimi.

4. Mekhoa e Sireletsehileng ea ho Tšoara

Boehmite ka boyona ha e-tjhefu, empa ho hema lerole ho ka baka ho teneha ha moya. Apara mask a N95 le likhalase ha u tšoara. Sebaka sa polokelo se lokela ho bolokoa se omme (mongobo o lekanyelitsoeng<40%) to avoid prolonged contact with strong acids and alkalis, which may damage the structure.

Ho tseba mekhoa e ka holimo ho ka ntlafatsa haholo katleho ea likopo tsa boehmite. Ho ntlafatsa ts'ebetso eohle, ho tloha ho khetho ea thepa ho ea ho taolo ea ts'ebetso, ke senotlolo sa ho lemoha bokhoni ba eona.
