Thetha malunga nosetyenziso lwei-hexagonal nano boron nitridekwintsimi ye-cosmetic

1. Izinto eziluncedo ze-hexagonal boron nitride nanoparticles kwindawo yokuthambisa

Kwintsimi ye-cosmetic, ukusebenza kakuhle kunye nokunyanzeliswa kwezinto ezisebenzayo esikhumbeni kuhambelana ngokuthe ngqo nobukhulu be-particle size, kwaye i-cosmetic particle size ibalulekile kuba i-particle diameters encinci inokunyusa ummandla kwaye inokuthi ifake i-cosmetic esebenzayo.I-hexagonal boron nitride (h-BN) nanomaterial inokulawula ubungakanani beengqungquthela ezidibeneyo.I-hexagonal boron nitride ineenzuzo ezicacileyo kwizinto zokuthambisa, ngokukodwa iimveliso ze-sunscreen, ezivumela ukuba i-nanostructures ilawulwe kwizigaba ezahlukeneyo zokuqulunqa ukulawula ubukhulu kunye nommandla;kwaye ineepropathi ezigqwesileyo ekusasazeni, i-non-toxic, i-transparency kunye ne-inert yekhemikhali.

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

Kuyaziwa ukuba imitha yelanga inokonakalisa impilo yolusu.Uluhlu lwamandla elanga luhlala lufikelela kumphezulu womhlaba yi-ultraviolet kunye ne-infrared.Iziphumo zokukhanya kwe-UV ziyingozi kwimpilo yolusu kwaye zinokubangela ukwanda komhlaza, ukuguga kunye nolunye utshintsho olungathandekiyo lwesikhumba, kwaye ziyasabela ekutshisweni lilanga, i-erythema kunye nokudumba.Imitha ye-infrared yonyusa umonakalo kunye nokuguga kwangaphambili kwemitha ye-ultraviolet eluswini, kwaye imitha ye-infrared inokuba namandla e-photocarcinogenesis.

Uphando loshishino lwezithambiso kwiimveliso zokukhusela ilanga sele lukhona ixesha elide.I-sunscreens iphuhliswe ngokusebenzisa i-nanoscience kunye nolwazi lwe-nanotechnology, njenge-nano titanium dioxide, into ebalulekileyo yokuthambisa i-sunscreen UV ray.Nangona kunjalo, ukhuseleko lwemitha ye-infrared, zimbalwa kakhulu izifundo ze-sunscreen, kwaye kulo mba, kuyimfuneko ukwenza i-sunscreens enika ukhuseleko lwe-UV kunye ne-IR.I-Boron nitride nanopowders zizinto ezinokubakho ngenxa yokuba zilawula ubungakanani beengqungquthela ezidibeneyo, eyona nto ibalulekileyo ekusetyenzisweni kwe-sunscreens.Kwakhona kunciphisa ukukhazimla kwesikhumba esinamafutha ngenxa ye-conductivity ephezulu ye-thermal.I-Titanium dioxide nanoparticles equlethe i-nanostructured boron nitride yindibaniselwano egqibeleleyo enokuthi isetyenziswe njengento yokuthambisa ukukhusela umzimba kwimitha yelanga ye-infrared.

Ngokuqinisekileyo, ukusetyenziswa kwe-hexagonal boron nitride nanoparticles kwintsimi yezimonyo ayikho kuphela i-sunscreen.Iindidi zezithambiso zityebile kakhulu.Ukongeza kwizinto zokuthambisa, ukusetyenziswa kweminye imimandla ye-hexagonal boron nitride nanoparticles nayo ibanzi kakhulu, kwaye ingasetyenziselwa ukuveliswa kweekeramics, ezifana ne-crucible, i-aluminium evaporation boats, i-substrates yebhodi yesekethe kunye nezithambisi eziphezulu zokushisa, nazo zisetyenziswa njengezinto zokwakha. yezixhobo zenyukliya kunye neeyunithi ze-rocket injini.
