Khuluma ngokusetshenziswa kwehexagonal nano boron nitrideEnsimini yezimonyo

1. Izinzuzo ze-hexagonal boron nitride nanoparticles emkhakheni wezimonyo

Ensimini yezimonyo, ukusebenza kahle nokuvumela okuthile esikhunjeni kuhlobene ngqo nosayizi wezinhlayiyana, futhi usayizi wezinhlayiyana wezimonyo kubalulekile ngoba ama-raid amancane wezinhlayiya angakhulisa indawo esebenzayo. I-hexagonal boron nitride (H-BN) nanomatale ingalawula usayizi wezinhlayiya ezihlanganisiwe. I-Hexagonal Boron Nitride inezinzuzo ezisobala ezimotweni, ikakhulukazi imikhiqizo yelanga, evumela ukuthi ama-nanostructure alawulwe ezigabeni ezahlukahlukene zokwakheka kokwakheka nokwakheka kwendawo yokulawula usayizi kanye nendawo engaphezulu; Futhi inezakhiwo ezinhle kakhulu ekuhlakazeni, okungelona ubuthi, ukucaca kanye nokuvuna kwamakhemikhali.

2. Ucwaningo lwe-infrared sunscreen sunscreen of nano boron nitride

Kuyaziwa ukuthi imisebe yelanga ingalimaza impilo yesikhumba. Ububanzi bamandla elanga ngokuvamile bufinyelela ebusweni bomhlaba yi-ultraviolet futhi infrared. Imiphumela yokukhanya kwe-UV iyingozi empilweni yesikhumba futhi ingahle iholele ekunciphiseni umdlavuza, ukuguga kanye nezinye izinguquko ezingathandeki zesikhumba, futhi ziphendulayo ekushisweni kwelanga, erfesthema kanye nokuvuvukala. Imisebe ye-infrared yandisa umonakalo kanye nokuguga kwangaphambi kokuguga kwemisebe ye-ultraviolet esikhunjeni, futhi imisebe ye-infrared nayo ingaba namandla okuthola izithombe.

Ucwaningo lwezimboni ze-COSMETICS ngemikhiqizo ye-sunscreen selikhona isikhathi eside. I-sunscreens iye yathuthukiswa kusetshenziswa i-nanoscience kanye nolwazi lwe-nanotechnology, njenge-nano titanium dioxide, impahla ebalulekile yezimonyo zemisebe yelanga ye-UV rays. Kodwa-ke, ukuvikela imisebe ye-infrared infrared, kunezifundo ezimbalwa kakhulu ze-sunsreen, futhi kulokhu, kuyadingeka ukwenza amalanga elanga ahlinzeka nge-UV ne-IR. AbakwaBoron Nitride Nanopowders bangaba yizinto ezingaba khona ngoba balawula usayizi wezinhlayiya ezihlanganisiwe, okuyisici esibalulekile ekusebenziseni ama-sunscreens. Iphinde inciphise i-luster yesikhumba esinamafutha ngenxa yokusebenza kwayo okuphezulu okuphezulu. I-Titanium Dioxide Nanoparticles equkethe ama-nenon nitride we-boron i-naron yinhlanganisela ephelele engasetshenziswa njengezimonyo ukuvikela umzimba emisebeni yelanga.

Vele, ukusetshenziswa kwe-hexagonal boron nitride nanoparticles emkhakheni wezimonyo akusilo kuphela ilanga. Izinhlobonhlobo zezimonyo zicebile kakhulu. Ngaphezu kwezimonyo, ukusetshenziswa kweminye imikhakha ye-hexagonal boron nitride nanoparticles kukhulu kakhulu, futhi kungafakwa izikebhe zokukhiqiza ze-ceramics, ezifana nezinto zokuthambisa ze-alucinutur, nazo zisetshenziswa njengezinto zokwakha ama-reactors we-nuclear kanye namayunithi enjini ye-rocket.
