Isingeniso Somkhiqizo: {65141-46-0} I-Silicon Dioxide Nanoparticles
Ama-silicon dioxide nanoparticles, anefomula yamakhemikhali ethi {65141-46-0}, ayinto eguquguqukayo kakhulu futhi eqanjwe kabusha eguqule izimboni ezihlukahlukene. Lawa ma-nanoparticles athole ukuthandwa okukhulu ngenxa yezakhiwo zawo ezihlukile zomzimba namakhemikhali, okuwenza akwazi ukusetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza. Ngezakhiwo zabo ezihlukile, i-silicon dioxide nanoparticles isishintshe umdlalo emkhakheni wezinto ezithuthukisiwe.
Ama-nanoparticles e-silicon dioxide ahlanganiswa ngenqubo elawulwa ngokucophelela eholela ezinhlayiyeni ezinobubanzi bebanga le-nanometers elingu-1 kuya ku-100. Lolu hlu losayizi lunikeza izinzuzo ezihlukile, njengoba luvumela ukuhlakazeka okungcono kanye nendawo engaphezulu, okuholela ekusebenzeni okuthuthukisiwe ezinhlelweni ezihlukahlukene. Ama-nanoparticles ngokuvamile asesimweni sempushana emhlophe, enezinga eliphezulu lokuhlanzeka elingaphezu kuka-99.5%.
Esinye sezici ezibalulekile ze-silicon dioxide nanoparticles yizindawo zabo ezinhle kakhulu zokubona. Banenkomba ephezulu ye-refractive, ebenza balungele ukwakhiwa kwama-optical coatings, amafilimu, namalensi. Lawa ma-nanoparticles angafakwa emigqonyeni ephikisana ne-reflective, okusiza ukunciphisa ukubonakaliswa okungafuneki nokuthuthukisa ukudluliswa kokukhanya. Ukusetshenziswa kwazo ezintweni ezibonakalayo kuqinisekisa ukucaca okuphakeme, ukumunca ukukhanya okuthuthukisiwe, nokugcwala kombala okuthuthukisiwe.
Ikhemikhali yangaphandle eyingqayizivele ye-silicon dioxide nanoparticles inikeza izinzuzo eziphawulekayo emkhakheni we-biotechnology nemithi. Ngenxa yendawo yawo enkulu kanye ne-porosity ephezulu, lawa ma-nanoparticles anamandla okukhangisa futhi aphathe izinhlobonhlobo zama-molecule, kuhlanganise nezidakamizwa nama-biomolecules. Lokhu kubenza babe yikhandidethi elihle kakhulu lezinhlelo zokulethwa kwezidakamizwa, lapho bengakwazi ukuthutha ama-ejenti wezokwelapha ngendlela efanele baye ezindaweni eziqondiwe emzimbeni. Ukwengeza, imvelo yabo ye-bioinert kanye ne-biocompatibility ibenza bafanelekele ukusetshenziswa kubunjiniyela bezicubu kanye nemithi evuselelayo.
Okunye ukusetshenziswa okuphawulekayo kwe-silicon dioxide nanoparticles kusemandleni abo okuthuthukisa izakhiwo zemishini yezinto ezihlukahlukene. Ngokuhlanganisa lawa ma-nanoparticles kuma-polymers, izinhlanganisela, kanye nama-coatings, izinto eziwumphumela zibonisa amandla athuthukisiwe, ubulukhuni, nokumelana nokuklwebheka. Lokhu kuvumela ukusetshenziswa kwazo ekuthuthukisweni kwezigqoko ezisebenza kahle kakhulu, izinamathiselo, nama-polymers aqinisiwe, okuholela emikhiqizweni ehlala isikhathi eside nehlala isikhathi eside.
I-silicon dioxide nanoparticles iphinde isetshenziswe kakhulu embonini ye-electronics. Ubukhulu bazo obuncane kanye nezakhiwo zikagesi eziyingqayizivele zibenza bafanelekele ukwenziwa kwezinto ezisebenza kahle kakhulu zikagesi. Angasetshenziswa njengama-filler kuma-paste e-elekthronikhi, ama-adhesives, nama-inki, okuvumela ukukhiqizwa kwamasekethe kagesi asebenzayo kanye nezingxenye.
Sengiphetha, ama-silicon dioxide nanoparticles, anefomula yamakhemikhali {65141-46-0}, anikeza izinzuzo eziningi ezihlukene ezimbonini ezimbalwa. Izakhiwo zazo ezingavamile, ezihlanganisa izici ezinhle kakhulu zokubona, ikhemistri yendawo ehlukahlukene, nokusebenza okuthuthukisiwe komshini, kuzenza ingxenye ebalulekile ezinhlelweni ezihlukahlukene ezifana nama-optical coatings, amasistimu okulethwa kwezidakamizwa, izinto zikagesi, nezinto ezithuthukisiwe. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, lezi nanoparticles zizoqhubeka nokufaka isandla ekuthuthukisweni kwemikhiqizo emisha neyinkimbinkimbi.
