Khuluma mayelana nokusetshenziswa kwei-hexagonal nano boron nitrideemkhakheni wezimonyo

1. Izinzuzo ze-hexagonal boron nitride nanoparticles emkhakheni wezimonyo

Emkhakheni wezimonyo, ukusebenza kahle kanye nokungena kwento esebenzayo esikhumbeni kuhlobene ngokuqondile nosayizi wezinhlayiyana, futhi usayizi wezinhlayiya zezimonyo ubalulekile ngoba ama-diameter ezinhlayiyana ezincane angase akhulise indawo engaphezulu futhi angase ahlanganise i-cosmetic esebenzayo.I-boron nitride eyi-hexagonal (h-BN) nanomaterial ingalawula usayizi wezinhlayiya eziyinhlanganisela.I-hexagonal boron nitride inezinzuzo ezisobala ezimonyoni, ikakhulukazi imikhiqizo yokuvikela ilanga, evumela ukuthi ama-nanostructures alawulwe ezigabeni ezihlukene zokubunjwa ukuze kulawulwe usayizi nendawo ephezulu;futhi inezindawo ezinhle kakhulu zokuhlakazeka, ezingenabuthi, obala kanye ne-inert yamakhemikhali.

2. Ucwaningo lwe-infrared sunscreen ye-Nano Boron Nitride

Kuyaziwa ukuthi imisebe yelanga ingalimaza impilo yesikhumba.Ububanzi bamandla elanga ngokuvamile afinyelela ebusweni bomhlaba yi-ultraviolet ne-infrared.Imiphumela yokukhanya kwe-UV iyingozi empilweni yesikhumba futhi ingase ibangele ukwanda komdlavuza, ukuguga nezinye izinguquko ezingathandeki zesikhumba, futhi isabela ekushiseni kwelanga, i-erythema nokuvuvukala.Imisebe ye-infrared yandisa umonakalo kanye nokuguga kwangaphambili kwemisebe ye-ultraviolet esikhumbeni, futhi imisebe ye-infrared ingase ibe namandla e-photocarcinogenesis.

Ucwaningo lwemboni yezimonyo ngemikhiqizo yokuvikela ilanga selunesikhathi eside lukhona.Izikhilimu zelanga zenziwe kusetshenziswa ulwazi lwe-nanoscience nolwazi lwe-nanotechnology, njenge-nano titanium dioxide, into ebalulekile yezimonyo yemisebe ye-UV evikela ilanga.Kodwa-ke, ukuze kuvikelwe imisebe ye-infrared, kunezifundo ezimbalwa kakhulu zokuvikela ilanga, futhi kulokhu, kuyadingeka ukwenza ama-sunscreens ahlinzeka ngokuvikelwa kwe-UV ne-IR.I-Boron nitride nanopowder yizinto ezingase zibe khona ngenxa yokuthi zilawula ubukhulu bezinhlayiya eziyinhlanganisela, okuyisici esibalulekile ekusetshenzisweni kwezikhilimu zelanga.Iphinde inciphise ukucwebezela kwesikhumba esinamafutha ngenxa ye-conductivity yayo ephezulu yokushisa.I-Titanium dioxide nanoparticles equkethe i-nanostructured boron nitride iyinhlanganisela ephelele engasetshenziswa njengesimonyo ukuvikela umzimba emisebeni yelanga ye-infrared.

Yiqiniso, ukusetshenziswa kwe-hexagonal boron nitride nanoparticles emkhakheni wezimonyo akuyona nje i-sunscreen.Izinhlobonhlobo zezimonyo zicebile kakhulu.Ngaphezu kwezimonyo, ukusetshenziswa kweminye imikhakha ye-hexagonal boron nitride nanoparticles nakho kubanzi kakhulu, futhi kungasetshenziswa ekukhiqizeni izitsha zobumba, njenge-crucible, izikebhe ze-aluminium evaporation, ama-substrates ebhodi lesifunda kanye nezigcobo zokushisa okuphezulu, nazo zisetshenziswa njengezinto zokwakha. ama-reactors enuzi namayunithi enjini yerokhethi.
