Pofuna kutetezedwa ndi dzuwa likupitiliza kukula, makampani opanga zodzikongoletsera amachitira umboni kuti chisinthiko chochititsa chidwi chomwe chimagwiritsidwa ntchito popanga mankhwala a mankhwala dzuwa. Nkhaniyi ikuwunikira njira yopitirira patsogolo ntchito zamankhwala dzuwa, ndikuwunikira kusinthasintha kwa zinthu zamakono zamakono zoteteza dzuwa.
Kufufuza Kwambiri Koyambirira:
Kumayambiriro kwa mitundu ya dzuwa, zosakaniza zachilengedwe monga zobzala, mchere, ndi mafuta ambiri nthawi zambiri amagwiritsidwa ntchito poteteza dzuwa. Ngakhale zosakaniza izi zidapereka mulingo wa radiation ya UV, zomwe zinali zovomerezeka ndipo zidasowa zotsatirapo zolimbitsa thupi.
Kukhazikitsidwa kwa Zosefera:
Kuchita bwino m'masamba oweta kwa mankhwalawa kunabwera ndi kuyambitsa zosefera zolengedwa, komwenso kumadziwika kuti UV okonda. M'zaka za m'ma 1900, asayansi adayamba kuyang'ana zinthu zachilengedwe kuthekera kotenga ma radiation a UV. Benzyl Sakylate adatulukira upainiyawo mu gawo ili, ndikupereka chitetezo cha UV. Komabe, kafukufuku winanso kunali kofunikira kukonza zomwe zikukwaniritsidwa.
Kupita patsogolo kwa chitetezo cha UVB:
Kupezeka kwa para-aminobenzoic acid (Paba) mu 1940s kunali chitetezero chachikulu padzuwa. Paba adakhala wofunikira kwambiri mu ma sunscreens, moyenera amatenga ma rayb othamanga omwe ali ndi kutentha kwa dzuwa. Ngakhale kuti ali ndi mphamvu, paba paba ndi malire, monga khungu kukhumudwitsana ndi ziwengo, zomwe zimapangitsa kufunikira kwa zosakaniza zina.
Chitetezero chowoneka bwino:
Zidziwitso za sayansi zimakulitsidwa, zomwe zimasunthidwa kuti zizipanga zosakaniza zomwe zingateteze ku UVB ndi UVA. Mu 1980s, avobenzone adatuluka ngati fayilo yogwira ntchito, kumaliza chitetezo cha UVB omwe alipo omwe adaperekedwa ndi dzuwa zochokera ku Dunscreens. Komabe, kukhazikika kwa avobenzoone pansi pa dzuwa kunali kovuta, kumapangitsa kuti zitheke zina.
Kutengera kosangalatsa komanso kokhazikika kwa UVA:
Kuti athe kuthana ndi kusakhazikika kwa zosefera zoyambirira za UVA, ofufuzawo amayang'ana kwambiri kukonzanso kujambula komanso kutetezedwa pang'ono. Zosakaniza ngati octocrylene ndi bemotrizol zidapangidwa, kupereka banja lokhazikika komanso chitetezo chapamwamba cha UVA. Kupita patsogolo kwakukulu kunali kothandiza kwambiri magwiridwe antchito ndi kudalirika kwa dzuwa.
Zosefera Ouca UV:
M'zaka zaposachedwa, zosefera za Ouva zatchuka chifukwa cha kutetezedwa kwawo kwa UVA komanso kukhazikika. Zophatikiza monga mexoryl sx, mexouryl Xl, ndi Timosorb s adasinthira ma sunscreens, kupereka chitetezo chambiri cha UVA. Zosakaniza izi zakhala zogwirizana ndi mapangidwe amakono a dzuwa.
Njira Zazikulu Zopanga:
Panthawi yopita patsogolo kupita patsogolo, njira zopangira zopanga zopanga zopangidwa zachita mbali yofunika kwambiri popititsa patsogolo magwiridwe antchito a dzuwa. Nanotechnology yatulutsa njira yoyesera michere, kupereka zojambulajambula ndikuwongolera mayamwidwe a UV. Tekinoloji yamisaikulu yakhala ikugwira ntchito kukonzanso kukhazikika ndikumatha kukhathamiritsa popereka, kuonetsetsa kufunikira kwakukulu.
Maganizo oyang'anira:
Ndikumvetsetsa kukula kwa dzuwa komwe kumapangitsa kuti thanzi laumunthu ndi chilengedwe, mabungwe owongolera akhazikitsa malangizo ndi zoletsa. Zosakaniza monga oxybenzone ndi Octinoxate, zomwe zimadziwika chifukwa cha zachilengedwe zomwe zingachitike, zalimbikitsa makampani kuti apange njira zina, zotetezera ndi kukhazikika.
Pomaliza:
Chisinthiko cha zosakaniza mu mankhwala owirikiza zamankhwala amasinthiratu kutetezedwa ndi dzuwa muzodzikongoletsera. Kuyambira zosefera koyambirira kwa chitukuko cha chitetezo chapamwamba cha UVA ndi njira zopangira magazi, mafakitalewo achita mbali zofunika kwambiri. Kupitiliza kufufuza ndi chitukuko kumatha kuyambitsa chilengedwe, chogwira mtima kwambiri, komanso chilengedwe, kuonetsetsa kuti ogula aogula.
