Bua ka tšebeliso eahexagonal nano boron nitridetšimong ea litlolo

1. Melemo ea hexagonal boron nitride nanoparticles tšimong ea litlolo

Sebakeng sa litlolo, ho sebetsa hantle le ho phunyeletsa ha ntho e sebetsang ka har'a letlalo ho amana ka ho toba le boholo ba likaroloana, 'me boholo ba likaroloana tsa litlolo bo bohlokoa hobane li-diameter tse nyenyane li ka eketsa sebaka se ka holim'a metsi' me li ka koahela setlolo se sebetsang.Hexagonal boron nitride (h-BN) nanomaterial e ka laola boholo ba likaroloana tse kopaneng.Hexagonal boron nitride e na le melemo e totobetseng ea litlolo, haholo-holo lihlahisoa tse sireletsang letsatsi, tse lumellang hore nanostructures e laoloe ka mekhahlelo e fapaneng ea ho thehoa ho laola boholo le sebaka se ka holimo;'me e na le thepa e babatsehang ea ho hasana, e se nang chefo, e pepeneneng le e sa sebetseng ka lik'hemik'hale.

2. Lipatlisiso tsa mahlaseli a mahlaseli a mahlaseli a mahlaseli a kotsi a letsatsi a Nano Boron Nitride

Hoa tsebahala hore mahlaseli a letsatsi a ka senya bophelo bo botle ba letlalo.Mefuta e mengata ea matla a letsatsi hangata e fihlang holim'a lefatše ke ultraviolet le infrared.Litlamorao tsa leseli la UV li kotsi bophelong ba letlalo mme li ka baka keketseho ea ts'oaetso ea mofetše, botsofali le liphetoho tse ling tse sa lakatseheng tsa letlalo, 'me li arabela ho chesoeng ke letsatsi, erythema le ho ruruha.Mahlaseli a infrared a eketsa tšenyo le ho tsofala pele ha mahlaseli a ultraviolet letlalong, 'me mahlaseli a infrared le ona a ka ba le monyetla oa ho etsa photocarcinogenesis.

Lipatlisiso tsa indasteri ea litlolo ka lihlahisoa tse sireletsang letsatsi li bile teng ka nako e telele.Li-sunscreens li entsoe ka tsebo ea nanoscience le nanotechnology, tse kang nano titanium dioxide, thepa ea bohlokoa ea litlolo bakeng sa mahlaseli a UV a sireletsang letsatsi.Leha ho le joalo, bakeng sa tšireletso ea mahlaseli a mahlaseli a kotsi, ho na le lithuto tse fokolang haholo tse sireletsang letsatsi, 'me tabeng ena, hoa hlokahala ho etsa li-sunscreens tse fanang ka tšireletso ea UV le IR.Boron nitride nanopowder ke lisebelisoa tse ka 'nang tsa e-ba teng hobane li laola boholo ba likaroloana tse kopantsoeng, e leng ntlha ea bohlokoa tšebelisong ea li-sunscreens.E boetse e fokotsa ho benya ha letlalo le mafura ka lebaka la conductivity ea eona e phahameng ea mocheso.Titanium dioxide nanoparticles e nang le nanostructured boron nitride ke motsoako o phethahetseng o ka sebelisoang e le setlolo ho sireletsa 'mele mahlaseling a letsatsi a infrared.

Ha e le hantle, ho sebelisoa ha hexagonal boron nitride nanoparticles tšimong ea litlolo ha se feela se sireletsang letsatsi.Mefuta e sa tšoaneng ea litlolo e ruile haholo.Ntle le litlolo, ts'ebeliso ea likarolo tse ling tsa hexagonal boron nitride nanoparticles le eona e atile haholo, 'me e ka sebelisoa ho etsa li-ceramics, joalo ka likepe tsa crucible, aluminium evaporation boats, substrates board board le lubricant e phahameng ea mocheso, le tsona li sebelisoa e le lisebelisoa tsa meralo. bakeng sa li-reactor tsa nyutlelie le likarolo tsa enjine ea rokete.
