Nano TiO2 inoshanda kune anti-ultraviolet:Nano-TiO2 inogona kutora ese ari maviri ultraviolet mwenje, asi zvakare inoratidzira, yakapararira ultraviolet mwenje, asi zvakare kuburikidza neinooneka mwenje, iri kuita kwepamusoro, inovimbisa kwazvo yekudzivirira yemuviri rudzi UV yekudzivirira mumiririri.

Nano-titanium dioxide anti-ultraviolet mechanism: Zvinoenderana neyakasiyana wavelengths, ultraviolet yakakamurwa kuita pfupi wavelength dunhu 190 ~ 280 nm, yepakati wave nzvimbo 280 ~ 320 nm, kureba wave nzvimbo 320 ~ 400nm.

Iyo pfupi-wave nzvimbo ine yakanyanya ultraviolet simba, asi inovharika kana yakaparadzaniswa neozone layer.Naizvozvo, kukuvadzwa kwemuviri wemunhu kunowanzo kuve pakati uye kureba wavelength nzvimbo.Iyo yakasimba UV inopikisa ye nano-titanium dioxide imhaka yekukwirira kwayo kwepamusoro uye kuita kwechiedza chepamusoro.Iyo anti-ultraviolet kugona kwayo uye maitiro ayo ane hukama nehukuru hwayo.

Kana iyo particle size yakakura, chipingamupinyi kune ultraviolet mwaranzi chinoratidzwa uye chakapararira, uye chinoshanda kune ese ultraviolet uye epakati wavelengths.Zuva rekudzivirira mashandiro chivharo chakareruka, inguva yakazara yezuva, sunscreen haina kusimba;nekukura kwechidimbu kunoderera, chiedza chinogona kupfuura ne nano-titanium dioxide particle surface, iyo yakareba wave ye ultraviolet chiedza chekuratidzira, kupararira hakusi pachena, uye Kutorwa kwechiedza che ultraviolet munzvimbo ye wave kunowedzera.

Iyo sunscreen mechanism ndeyekutora ultraviolet mwenje, kunyura kukuru kwechiedza che ultraviolet munzvimbo yemafungu. Zvinogona kuoneka kuti nano-titanium dioxide pane akasiyana wavelengths ye ultraviolet radiation michina haina kufanana, iyo yakareba-wave nzvimbo yeUV. block kune iyo huru yekuparadzira, iyo UV wave munzvimbo yemafungu kuti itore iyo huru.

Nano-titanium dioxide mune zvakasiyana-siyana zvewavelengths zvakaratidza zvakanakisa kunyura zvivakwa, zvichienzaniswa nemamwe organic sunscreen, nano-titanium dioxide ine isiri-chepfu, yakagadzikana kuita, yakanaka mhedzisiro uye zvichingodaro.Nano-titanium dioxide nekuda kwediki particle size, basa rakakura, zvese zvinoratidzira, zvakapararira ultraviolet mwenje, asi zvakare inotora ultraviolet mwenje, ine simba rakasimba rekuvharira UV.

Kuenzaniswa nemwero mumwechete weiyo organic UV inodzivirira mumiririri, HWNANO nano-titanium dioxide mu ultraviolet absorption peak yakakwirira, inonyanya kukosha iyo yakafara spectrum yekudzivirira maajenti, kusiyana neiyo organic UV inodzivirira inotorwa chete UVA kana UVB.
