I-Nanotechnology kunye ne-nanomasters: I-Nanometer Titanium Dioxide kwi-sunscreen cosmetics

Amagama ecawa

Malunga ne-5% ye-rays i-piat lilanga linemitha ye-ultraviolet ene-wavelength ≤400 NM. I-Ultraviolet imitha yokukhanya kwelanga inokwahlulwa ibe yi: I-Wave-Wave-Wave-Waves-quiths ezingama-320 NM ~ 400 NM, ebizwa ngokuba yi-Utraviolet Roys (i-UVA); I-Adraviolet ye-Preyraviolet enezakhono ezingama-290 NM ukuya kwi-320 NM zibizwa ngokuba yi-B-Chwethelwe i-otraviolet rays

Ngenxa ye-wavelength yayo emfutshane kunye namandla aphezulu, imitha ephakamileyo ye-Ultraviolet inamandla amakhulu, enokonakalisa ulusu lwabantu, lubangela umhlaza wolusu. I-UVB yeyona nto iphambili ebangela ukuvuvukala kwesikhumba kunye nokukhanya kwelanga.

1. Umgaqo wokukhusela i-ultraviolet rays nge-nano tio2

I-tio _ 2 luhlobo lwe-N-Cemimonductor. Ifom yekristali ye-nano-tio _ 2 isetyenziswe kwi-sunscreen cossoen ngokubanzi, kwaye i-In EVELT I-TIO i-I-ITARD i-400nm ye-iv ifakwe kwi-rays, kwaye i-ECO-Hos e-EV _ 2 inomsebenzi yokufumana imitha ye-UV. Ngobukhulu obukhulu obuncinci kunye namaqhezu amaninzi, oku kukhulisa kakhulu ukubakho kokuthintela okanye ukunikezela i-ultraviolet rays.

2. Iimpawu ze-nano-tio2 kwi-sunscreen cosmetics

2.1

Ukukhusela ukusebenza kakuhle kwe-UV

I-Ultraviot yamandla okukhusela i-ultraviolet ye-sunscreen cosmetics ibonakaliswa yinto yokukhutshelwa ilanga (ixabiso leSPF), kunye nexabiso eliphezulu le-SPF, elona qhina lwelanga. Umyinge wamandla afunekayo ukuvelisa i-Erythema ephantsi ebonakalayo yolusu elinamandla kumandla afunekayo ukuvelisa i-Erythema yenqanaba elifanayo le-STARKROEEN.

Njengoko i-nano2 i-tio2 ifumana kwaye ichithe imisebe ye-Utraviolet, ithathwa njengeyona ndawo ilungileyo yelanga ekhaya nakwamanye amazwe. Ngokubanzi, ubuchule be-nano-tio2 ukuya kwi-Shield UVB ngamaxesha ama-3-4 akwenzeka kwe-nano-zno.

2.2

Ubungakanani be-subricle yeyunithi efanelekileyo

I-Ultraviot yamandla e-Ultraviolet ye-Nano-Tio2 igqitywe ngamandla ayo okufudukayo kunye nokukwazi ukusasaza. Incinci ye-subricle ye-subsicle ye-nano-tio2, eyomeleleyo kakhulu i-ultraviolet yokuqalisa. Ngokutsho komthetho kaRanyaigh osasazekileyo, kukho ubungakanani be-suvaltal yentsusa yendawo yokuqalisa kwe-nano-tio2 ukuya kwi-Ultraviolet rays ngamaza ahlukeneyo. Iimvavanyo zikwabonisa ukuba ixesha elide i-wavelength rays, amandla okufihlwa kwe-nano-tio 2 axhomekeke ngakumbi kubuchule bayo bokusasazeka; Ukufutshane i-wavelength yento, kokukhuselwa kwayo kuxhomekeke kubuchule bayo bokwamkela.

2.3

Ukungahambi kakuhle kunye nokungafihlisi

Ubungakanani bentsusa ye-Nano-Tio2 ingaphantsi kwe-100 nm, ngaphantsi kokukhanya okubonakalayo. Ithiyori, i-nano-tio2 inokudlulisela ukukhanya okubonakalayo xa isasazeke ngokupheleleyo, ngoko ke isebala. Ngenxa yokungafihli kwe-nano-tio2, ayiyi kugubungela ulusu xa longezwa kwi-scuttics yelanga. Ke ngoko, inokubonisa ubuhle bolusu lwendalo.Ukuba nenye yezalathiso ezibalulekileyo ze-nano-tio2 kwi-sunscreen cossoetics. Ngapha koko, i-Nano-tio 2 iselubala kodwa ingabonakali ngokupheleleyo kwi-suscreenics yelanga, kuba i-nano-tio2 inamasuntswana amancinci, kwaye kulula kakhulu ukwenza i-Agegregates, oko kuchaphazela ukungafihlisi iimveliso.

2.4

Ukuxhathisa okuhle kwemozulu

I-Nano-tio 2 ye-sunscreen cossoection ifuna ukumelana nemozulu (ngakumbi ukumelana nokukhanya okukhanyayo). Kuba i-nano-tio2 inamasuntswana amancinci kunye nomsebenzi ophezulu, iya kuvelisa izibini ze-enctroning rays, kunye nezibini ze-eldroxyl kwi-Otomical Deamicals kwi-One-Idesication ye-Oner iziqholo. Ke ngoko, enye okanye engabonakaliyo yokuzibopha, njenge-silica, ialumini kunye ne-ziirconia, kufuneka idityaniswe kumphezulu we-nano-tio2 ukuthintela umsebenzi wefotocamical.

I-3. Iindidi kunye nendlela yophuhliso ye-nano-tio2

3.1

I-Nano-Tio2 powder

Iimveliso ze-Nano2 zithengiswa ngohlobo lomgubo oqinileyo, onokwahlulwa kwi-hydrophilic powder kunye ne-lipophilic powder ngokwemigangatho ye-NANo-TIO2. I-hydrophilic powder isetyenziswa kwi-cosmetics esekwe emanzini, ngelixa i-lipophilic powder isetyenziswa kwi-cosmetics esekwe kwi-oyile. I-hydrophilic powders ifunyenwe ngokubanzi ngonyango lwe-inrganic phesheya. Eyona nto iphambili kwezi mpompo ze-nano-tio ze-Nano2 zenziwe ngonyango olukhethekileyo ngokommandla wabo wesicelo.

3.2

Umbala webala le-nano tio2

Kungenxa yokuba i-Nano2 amasuntswana alungile kwaye kulula ukusasaza ukukhanya okuluhlaza okwesibhakabhaka esifutshane ngesikhanyiso esibonakalayo, xa usongezwa kwithoni eblue kwaye ijongeke ngokungalunganga. Ukwenzela ukutshatisa umbala wolusu, imibala ebomvu njenge-Iron Oxide ihlala yongezwa kwifomula ye-cosmetic eqingqiweyo. Nangona kunjalo, ngenxa yomehluko kuxinzelelo kunye ne-upott ephakathi kwe-nano-tio2 _ 2 kunye nentsimbi yentsimbi, imibala edadayo ihlala yenzeka.

I-4. Imo yemveliso ye-nano-tio2 e China

Uphando oluncinci lwe-nano-tio2 _ 2 e-China lusebenza kakhulu, kwaye inqanaba lophando lwethiyori lifikelele kwinqanaba eliphezulu, kodwa uphando olusetyenzisiweyo nophando lungabuyisi umva kwiimveliso zeshishini. Ukuveliswa kwemveliso ye-Nano-Tio2 e-China kwaqala ngo-1997, ngaphezu kweminyaka eli-10 ngaphambi kweJapan.

Kukho izizathu ezibini ezithintela umgangatho kunye nokhuphiswano lwentengiso lweemveliso ze-NAno-tio2 eTshayina:

Itekhnoloji yoPhando lweTekhnoloji yeTekhnoloji ngasemva

UPhando lweTekhnoloji yokuSebenzisa ukusombulula iingxaki zongezo lwenkqubo kunye nokuvavanywa kwe-nano-tio2 kwinkqubo yokuhlanganisa. UPhando lwesicelo se-nano-tio2 kwimimandla emininzi ayikhange iphuhliswe ngokupheleleyo, kwaye uphando kwezinye iindawo, ezinjengee-Nano-Tio-Tio-Tio-Tio-Tio-Tio-Tio-Tio-Gio-Tio-TIO2 _ 2 iimveliso azinakukwazi ukuhlangabezana neemfuno ezizodwa zeenkalo ezahlukeneyo.

② Itekhnoloji yoNyango ye-Nano-Tio2 ifuna ukuqhubeka nokufunda

Unyango lomhlaba lubandakanya unyango lwe-inrganic lonyango kunye nonyango lwe-organic. Itekhnoloji yoNyango yoNyango iqumba ifomula yonyango lomphezulu, itekhnoloji yonyango engaphezulu kunye nezixhobo zonyango.

5. Ukuqukumbela amagqabantshintshi

Ukungafihlisi, ukusasazeka kunye nokuchasana nokuxhathisa ukukhanya kwe-nano-tio2 kwi-sunschetics zelanga kubalulekile ukugweba umgangatho wayo, kunye nenkqubo yonyango lwe-Nano-Tio2 yeyona nto iphambili ekumiselweni ezi zikhondyungqi zobugcisa.
