Nano TiO2 ua haujlwm rau kev tiv thaiv ultraviolet:Nano-TiO2 tuaj yeem nqus tau ob qho tib si ultraviolet lub teeb, tab sis kuj muaj kev cuam tshuam, tawg tawg ntawm ultraviolet lub teeb, tab sis kuj los ntawm lub teeb pom kev, yog qhov ua tau zoo tshaj plaws, kev cog lus lub cev tiv thaiv hom UV tiv thaiv tus neeg saib xyuas.

Nano-titanium dioxide anti-ultraviolet mechanism: Raws li qhov sib txawv wavelengths, ultraviolet muab faib ua luv wavelength cheeb tsam 190 ~ 280 nm, nruab nrab yoj cheeb tsam 280 ~ 320 nm, ntev yoj cheeb tsam 320 ~ 400nm.

Qhov luv-yoj cheeb tsam muaj lub zog siab tshaj plaws ntawm ultraviolet, tab sis raug thaiv thaum nws raug cais tawm ntawm txheej ozone.Yog li ntawd, kev puas tsuaj rau tib neeg lub cev yog feem ntau nyob rau hauv nruab nrab thiab ntev wavelength cheeb tsam.Qhov muaj zog UV tsis kam ntawm nano-titanium dioxide yog vim nws lub siab refractive thiab lub teeb ua haujlwm siab.Nws lub peev xwm los tiv thaiv ultraviolet thiab nws cov txheej txheem muaj feem xyuam rau nws qhov loj me.

Thaum lub particle loj loj, lub teeb meem rau ultraviolet rays yog reflected thiab tawg, thiab nws yuav siv tau rau ob qho tib si ultraviolet thiab nruab nrab wavelengths.Lub hnub tiv thaiv mechanism yog ib qho yooj yim npog, yog ib tug dav lub cev tshuaj pleev thaiv hnub, tshuaj pleev thaiv hnub tsis muaj zog;Nrog rau qhov loj me me zuj zus, lub teeb tuaj yeem dhau los ntawm nano-titanium dioxide particle nto, qhov ntev nthwv dej ntawm lub teeb pom kev ntawm ultraviolet, tawg yog tsis pom tseeb, thiab qhov nqus ntawm ultraviolet lub teeb nyob rau hauv yoj cheeb tsam yog pom tseeb txhim kho.

Lub tshuab tshuaj pleev thaiv hnub yog kom nqus tau lub teeb ultraviolet, lub ntsiab nqus ntawm ultraviolet lub teeb nyob rau hauv qhov chaw yoj.Nws tuaj yeem pom tias nano-titanium dioxide ntawm qhov sib txawv wavelengths ntawm ultraviolet hluav taws xob mechanism tsis zoo ib yam, qhov ntev-yoj cheeb tsam ntawm UV. thaiv mus rau lub ntsiab tawg, UV nthwv dej nyob rau hauv yoj cheeb tsam kom nqus tau lub ntsiab.

Nano-titanium dioxide nyob rau hauv qhov sib txawv wavelengths tau pom zoo heev nqus cov khoom, piv nrog rau lwm cov organic tshuaj pleev thaiv hnub, nano-titanium dioxide uas tsis yog-tshuaj lom, ruaj khov kev ua tau zoo, cov nyhuv zoo thiab lwm yam.Nano-titanium dioxide vim me me particle loj, kev ua haujlwm loj, ob qho tib si reflective, tawg tawg ultraviolet lub teeb, tab sis kuj nqus ultraviolet lub teeb, uas muaj peev xwm tiv thaiv UV.

Piv nrog rau qee qhov tib koob tshuaj ntawm cov organic UV tiv thaiv tus neeg saib xyuas, HWNANO nano-titanium dioxide nyob rau hauv ultraviolet absorption ncov siab dua, muaj txiaj ntsig ntau dua nws yog qhov dav ntawm cov tshuaj tiv thaiv, tsis zoo li cov organic UV tiv thaiv tus neeg saib xyuas uas tsuas yog ib qho UVA lossis UVB nqus.
