Ultraviolet riys ndeimwe yezvikamu zvakakosha zvezuva, uye maimbe avo anogona kukamurwa kuita mabhendi matatu. Pakati pavo, Uvc ipfupi masaisai, iyo inobviswa uye yakavharwa neOzone layer, haigone kusvika pasi, uye haina simba pamuviri wemunhu. Naizvozvo, uva neUVB mune ultraviolet riys ndiyo huru mavhiri ekuwongorora anokonzera kukuvara kweganda revanhu.

Hongwu nano'stitanium dioxide (tio2) nanipowderine zvidiki zvidiki zvidiki, zvakakwirira zviitiko, zvakakwirira zvinotsorodza zvivakwa uye zvakakwirira Photofaactivity. Izvo hazvigone kungofungisisa uye kuparadzira ultraviolet riys, asi zvakare ubate, nokudaro kuve nesimba rekuvhara kurwisa UV ravana. Iko kuvimbisa mumuviri uv-kuchengetedza kuchengetedza nekuita kwepamusoro kuita.

Iyo Anti-Uv kugona kweNano Tio2 inoenderana nehukuru hwayo hwevhu. Kana saizi yeTitanium yeTitaniide Naneoparticle iri ≤300nm, iyo Ultraviolet rims ine wavelengths pakati pa190 uye 400nm inonyanya kuratidzwa uye yakapararira; Kana saizi yeTitania nanopowder ndeye <200nm, iyo UV kuramba inonyanya kuratidzwa uye yakapararira. Zuva rekudzivirirwa kwezuva rekudzivirirwa kweiyo Ultraviolet mbambo dziri pakati pematunhu uye marefu, uye kugona kuchengetedzwa kwezuva hakuna kusimba; Kana iyo sizi size ye tii2 nano poda pakati pe30 uye dentrption yeiyo Ultraviolet rays in the svikingi inzvimbo inovandudzwa zvakanyanya, uye yekuchengetedza midziyo pane ultraviolet rays ndiyo yakanyanya kunaka. Zvakanaka, zuva rayo rekudzivirirwa kwezuva ndeyekunyura ultraviolet rangi.

Kuputa,titanium dioxide nano templeane akasiyana ezuva rekudzivirira michina yemasangano akasiyana ekuwongorora kweiyo ultraviolet rangi. Kana iyo wavelength yeUltraviolet riys iri kureba, iko kuita kwekunyepedzera kweNano titanium dioxide tio2 zvinoenderana nekugona kwayo; Kana iyo wavelength yeiyo ultraviolet riys ipfupi, kuita kwayo kwekuvhara kunoenderana nekugona kwayo. Ndiko kuti, nano titanium ye oxide kugona kwekudzivirira kudzora kwehupamhi makuhwa Iyo diki iyo yekutanga chidimbu chidimbu, iyo yakasimba iyo UV yekuwedzera kugona kwe nano titanium dioxide poder.

Ongororo dzinoratidza kuti hongwu nano's nano rutile titanium dioxide tio2 ine zvirinani uv midziyo yekuchengetedza kupfuura nano auntase tio2. NANO TIO2 TIO2 ine yakanaka yekushandisa tarisiro muAnti-uv kupedzisa kwemachira ekotoni uye mune anti-ultraviolet machira pane girazi rekusimbisa.
