Quote mazwi

Vanenge 5% yemakanda akaparadzaniswa nezuva ivhu rave kurwa nemarara ane wavelength ≤400 nm. Ultraviolet Rays muchiedza chezuva chinogona kukamurwa mu: wave-wave ultraviolet rays ine wavelength ye 320 nm ~ 400 nm, inonzi a-type ultraviolet rays (uva); Pakati-MaWave Ultraviolet Rays ane wavelength of 290 nm kusvika ku20 nm

Nekuda kwe pfupi pfupi wavelength uye yakakwira simba, Ultraviolet riys ine simba rakakura, izvo zvinogona kukuvadza ganda revanhu, kukonzera kuzvimba kana kuiswa kwezuva, uye zvakakomba cancer. UVB ndiyo yakakosha chikonzero chinokonzeresa kusvinura kweganda uye zuva.

1. Iyo nheyo yekudzivirira ultraviolet rays ine nano tio2

Tio _ 2 ndeye N-Type Semiconductor. Iyo Crystal Fomu reNano Kubvisa UV Rays. Nezvishoma zvidiki zvevakakura zvidiki uye zvidimbu zvakawanda, izvi zvinowedzera zvakanyanya mukana wekuvharira kana kudzikisira ultraviolet rays.

2. Hunhu hweNano-tio2 mune sunscreen cosmetics

2.1

High Uv Shoeling Kubudirira

Iko kultraviolet kugona kwekuchengetedza kwezuva kweSunscreen cosmetics kunoratidzwa neyekudzivirirwa kwezuva chinhu (SPF kukosha), uye yakakwira kukosha kweSpf, zviri nani zuva rakatsvuka. Iyo ratio yesimba inodiwa kuti uburitse yakaderera erythema yeganda yakaiswa nezvigadzirwa zveSunscreen kune iyo simba inodiwa kuti igadzire erythema yeganda isina zvigadzirwa zvisina tsanga.

Sezvo nano-tii2 inobata uye inoparadzira ultraviolet rays, inoonekwa seyakainakidza kwazvo sunscreen pamba uye kunze kwenyika. Muzhinji, kugona kweNano-tii2 to shield UVB ndeye 3-4 nguva iyo yaNano-zno.

2.2

Saizi yakakodzera size size

Iyo Ultraviolet Kuchengetedza kugona kweNano-tio2 inotsanangurwa nekugona kwayo kugona uye kupararira kugona. Izvo zvidiki izvo zvekutanga zvechikamu cheNano-tio2, iyo yakasimba iyo Ultraviolet yekuwedzera kugona. Sekureva kweRalyleg's Mutemo wechiedza, pane yakakwana yekutanga sizi yehukuru hwekugona kuwanda kwekugona kwekugona kuwanda Kuedza kunoratidzawo kuti iyo yakareba iyo wavelength yeUltraviolet rays, kugona kwekuchengetera nano-tio 2 zvinoenderana nekugona kwayo; Iyo ipfupi iyo wavelength, iyo more mhanje riripo zvichienderana nekugona kwayo.

2.3

Yakanakisa Kupararira uye Kujeka

Iyo yekutanga sizele size ye nano-tio2 iri pazasi pe100 nm, kure pasi pemucherechedzo wechiedza chinooneka. Zvinonzwisisika, nano-tii2 inogona kuendesa mwenje unooneka kana ikaparadzirwa zvakakwana, saka inoonekera. Nekuda kweiyo transcapency of nano-tio2, haizofukidze ganda kana rakawedzerwa muzuva reSunscreen cosmetics. Naizvozvo, inogona kuratidza nhungamiro yeganda yeganda.Rransparcy ndeimwe yeiyo yakakosha indexes yeNano-tio2 mune sunscreen cosmetics. Muchokwadi, nano-tio 2 inojekesa asi isina kuzoratidzwa mune sunscreen cosmetics, nekuti nano-tii2 ine nzvimbo yakakura, uye iri nyore kuumbwa, nekudaro ichikanganisa kuparadzaniswa uye kujeka kwezvigadzirwa.

2.4

Kunaka Kwemamiriro ekunze

Nano-Tio 2 yeSunscreen Cosmetics inoda zvimwe zvekurwisa mamiriro ekunze (kunyanya kujeka kuramba). Nekuti nano-tii2 ine zvidiki zvidiki uye zvakakwirira zvezviitiko zvegomba mushure mekupaza kwemvura. Naizvozvo, mumwe kana anopfuura exolates yekuzviparadzaniswa, senge silica, Alumina naZirconia, vanofanirwa kuunganidzwa pamusoro peNano-tio2 kuti vimbise basa rayo.

3. Mhando uye Development maitiro eNano-tio2

3.1

Nano-tio2 poda

Iyo nano-tio2 zvigadzirwa inotengeswa muchimiro chemufuro akasimba, izvo zvinogona kukamurwa kuita hydrophic poda uye lipophic poda maererano nezvivakwa zveNano2. Hydrophic poda inoshandiswa mumvura-inokonzerwa nemavara-mashandiro emvura, nepo lipeilic poda inoshandiswa mumafuta-anodzvanywa cosmetics. Hydrophic Poders inowanzo kuwanikwa neINorganic pamusoro pekurapa kumukati meiwo maNano-Tio2 podaders yakavezwa sosi inokosha maererano neminda yavo yekushandisa.

3.2

Rara ganda nano tio2

Nekuti nano-tii2 manhamba akanaka uye ari nyore kuparadzira mwenje webhuruu neyepfupi wavelength mumazino anoonekwa, kana akawedzerwa muzvinyaradzi, ganda rinoratidza bhuruu toni uye tarisa zvisina kunaka. Kuti ufanane neganda reruvara, dzvuku dzakatsvuka senge simbi oxide dzinowanzowedzerwa kune cosmetic mafomula mune yekutanga nhanho. Nekudaro, nekuda kwemusiyano mune density uye yakanyorovesa pakati peNano2 _ 2 uye simbi oxide, mavara mavara anowanzoitika.

4. Kugadzira chimiro cheNano-tio2 kuChina

Diki-Boka Rwiyo paNano2 _ 2 kuChina inoshanda, uye iyo yekutsvagisa yekutsvagisa nyika Yakasvika padanho, Kugadzirwa kwemaindasitiri kwaNano2 muChina kwakatanga muna 1997, anopfuura makore gumi gare gare kupfuura Japan.

Pane zvikonzero zviviri izvi zvinodzora mhando uye musika kukwikwidza kweNano-tio2 zvigadzirwa muChina:

❑ Zvakanyorera technology kutsvagisa lags kumashure

Iyo yekushandisa tekinoroji yekutsvaga inoda kugadzirisa matambudziko ekuwedzera maitiro uye maitiro ekuongororwa kweNano-tio2 mune composite system. Kutsvaga kwekushandisa kwaNano2 Tio2 muminda yakawanda hakuna kugadzirwa zvizere, uye nekumwe mitezo, zvakadai

② Iyo yekumanikidza kurapwa tekinoroji yeNano-tio2 inoda kuenderera mberi kudzidza

Kurapa kwepasi kunosanganisira malorganic pamusoro pekurapa uye organic pamusoro pekurapwa. Surventional kuronga tekinoroji yakaumbwa neyekumusoro kurapwa mumiririri formula, pamusoro pekurapa tekinoroji uye midziyo yekurapa.
