Ultraviolet mwaranzi chimwe chezvinhu zvakakosha zvechiedza chezuva, uye wavelength yavo inogona kukamurwa kuita mabhendi matatu. Pakati pavo, UVC inguva pfupi, iyo inobatwa uye yakavharwa ne ozone layer, haigoni kusvika pasi, uye haina mhedzisiro inokuvadza pamuviri wemunhu. Naizvozvo, UVA neUVB mumiranzi yeultraviolet ndiwo mabhendi makuru ewavelength anokonzera kukuvadza paganda remunhu.

Hongwu Nano'stitanium dioxide (TiO2) nanopowderine diki diki saizi, yakakwira chiitiko, yakakwira refractive zvivakwa uye yakakwirira photoactivity. Iyo haingogone kuratidza uye kuparadzira ultraviolet mwaranzi, asi zvakare inoatora, nekudaro kuve nekudzivirira kwakasimba kugona kurwisa UV mwaranzi. Iyo inovimbisa yemuviri UV-inodzivirira inodzivirira ine yepamusoro kuita.

Iyo anti-UV kugona kwe nano TiO2 ine hukama nehukuru hwayo. Kana iyo particle size yetitanium dioxide nanoparticle iri ≤300nm, iyo ultraviolet mwaranzi ine wavelengths pakati pe190 ne400nm inonyanya kuratidzwa uye yakapararira; kana saizi yetitania nanopowder iri <200nm, kupikisa kweUV kunonyanya kuratidzwa uye kupararira. Iyo nzira yekudzivirira yezuva yemirairo ye ultraviolet munzvimbo yepakati-wave uye yakareba-wave nharaunda iri nyore kuvhara, uye simba rekudzivirira zuva harina simba; apo saizi yeTiO2 nano powder iri pakati pe30 ne100nm, kutorwa kwemwaranzi ye ultraviolet munharaunda yepakati-wave kunowedzera zvakanyanya, uye kudzivirira mhedzisiro pamirayi ye ultraviolet ndiyo yakanyanya kunaka. Zvakanaka, nzira yayo yekudzivirira zuva ndeyekutora ultraviolet mwaranzi.

Kupedzisa,titanium dioxide nano particleine nzira dzakasiyana dzekudzivirira zuva kune dzakasiyana wavelengths yemirairo ye ultraviolet. Kana iyo wavelength yemirayi ye ultraviolet iri kureba, iyo shielding performance ye nano titanium dioxide TiO2 zvinoenderana nekukwanisa kwayo kuparadzira; kana kureba kwemwaranzi ye ultraviolet ipfupi, kuita kwayo kwekudzivirira kunoenderana nekugona kwayo kunyudza. Kureva kuti, nano titanium oxide kugona kudzivirira mwaranzi yeultraviolet inotarwa nekugona kwayo kunyudza uye kugona kwekuparadzira. Iyo idiki iyo yekutanga particle size, iyo yakasimba iyo UV yekunyudza kugona kwe nano titanium dioxide hupfu.

Zviyedzo zvinoratidza kuti Hongwu Nano's nano rutile titanium dioxide TiO2 ine zvirinani UV kudzivirira zvivakwa pane nano anatase TiO2. Nano TiO2 ine tarisiro yakanaka yekushandisa mukudzivirira-UV kupera kwemachira edonje uye mune anti-ultraviolet coatings pane insulating girazi.
