Kambiranani za kugwiritsa ntchitohexagonal nano boron nitridem'munda wa cosmetology

1. Ubwino wa hexagonal boron nitride nanoparticles m'munda wa zodzikongoletsera

M'munda wa zodzikongoletsera, mphamvu ndi permeability ya mankhwala yogwira pakhungu ndi mwachindunji zogwirizana ndi tinthu kukula, ndi zodzikongoletsera tinthu kukula n'kofunika chifukwa ang'onoang'ono tinthu diameters akhoza kuonjezera kumtunda ndipo akhoza encapsulate zodzikongoletsera yogwira.The hexagonal boron nitride (h-BN) nanomaterial akhoza kulamulira kukula kwa gulu particles.Hexagonal boron nitride ali ndi ubwino zoonekeratu mu zodzoladzola, makamaka sunscreen mankhwala, amene amalola nanostructures kulamulidwa pa magawo osiyanasiyana mapangidwe kulamulira kukula ndi pamwamba dera;ndipo ili ndi zinthu zabwino kwambiri zobalalika, zopanda poizoni, zowonekera komanso zotulutsa mankhwala.

2. Infrared radiation sunscreen kafukufuku wa Nano Boron Nitride

Ndizodziwika bwino kuti kuwala kwa dzuwa kumatha kuwononga thanzi la khungu.Mitundu ya mphamvu ya dzuwa nthawi zambiri imafika padziko lapansi ndi ultraviolet ndi infrared.Zotsatira za kuwala kwa UV ndizowopsa ku thanzi la khungu ndipo zimatha kupangitsa kuchuluka kwa khansa, kukalamba ndi kusintha kwina kosafunika kwa khungu, ndipo kumagwirizana ndi kutentha kwa dzuwa, erythema ndi kutupa.Kuwala kwa infrared kumawonjezera kuwonongeka ndi kukalamba kwa cheza cha ultraviolet pakhungu, ndipo ma radiation a infrared amathanso kukhala ndi kuthekera kwa photocarcinogenesis.

Kafukufuku wa makampani opanga zodzoladzola pa zinthu zodzitetezera ku dzuwa akhala akugwira ntchito kwa nthawi yaitali.Ma sunscreens apangidwa pogwiritsa ntchito chidziwitso cha nanoscience ndi nanotechnology, monga nano titanium dioxide, chinthu chofunikira chodzikongoletsera cha kuwala kwa dzuwa kwa UV.Komabe, pofuna kuteteza ma radiation a infrared, pali maphunziro ochepa oteteza dzuwa, ndipo pankhaniyi, ndikofunikira kupanga zoteteza ku dzuwa zomwe zimapereka chitetezo cha UV ndi IR.Boron nitride nanopowders ndi zinthu zomwe zingatheke chifukwa zimayang'anira kukula kwa tinthu tating'onoting'ono, zomwe ndizofunikira kwambiri pakugwiritsa ntchito mafuta oteteza dzuwa.Amachepetsanso kunyezimira kwa khungu lamafuta chifukwa cha kuchuluka kwake kwamafuta.Titaniyamu woipa nanoparticles munali nanostructured boron nitride ndi wangwiro kuphatikiza kuti angagwiritsidwe ntchito ngati zodzikongoletsera kuteteza thupi ku infuraredi cheza dzuwa.

Kumene, ntchito hexagonal boron nitride nanoparticles m'munda wa zodzoladzola osati sunscreen.Zodzoladzola zosiyanasiyana ndizolemera kwambiri.Kuphatikiza pa zodzoladzola, kugwiritsa ntchito madera ena a hexagonal boron nitride nanoparticles nawonso kwambiri, ndipo angagwiritsidwe ntchito ziwiya zadothi kupanga, monga crucible, zitsulo zotayidwa evaporation mabwato, dera gawo lapansi ndi lubricant kutentha, amagwiritsidwanso ntchito ngati zipangizo structural. kwa ma reactor a nyukiliya ndi mayunitsi a injini ya roketi.
