Chitetezo ku dzuwa^®DPDT (Disodium Phenyl Dibenzimidazole Tetrasulfonate): Chopangira Choteteza Dzuwa Kuti Muteteze Dzuwa Moyenera

Mu dziko lomwe likusintha nthawi zonse la chisamaliro cha khungu ndi chitetezo cha dzuwa, ngwazi yatsopano yatuluka mu mawonekedwe aChitetezo ku dzuwa^®DPDT (Disodium Phenyl Dibenzimidazole Tetrasulfonate)Chosakaniza chatsopanochi cha mafuta oteteza ku dzuwa chakhala chikudziwika kwambiri m'makampani chifukwa cha luso lake lodabwitsa lopereka chitetezo chabwino cha UVA, chomwe chimasiyanitsa ndi zosefera zina za UV.

Chitetezo ku dzuwa^®DPDT (Disodium Phenyl Dibenzimidazole Tetrasulfonate)ndi mankhwala osungunuka m'madzi omwe amathandiza kwambiri kuyamwa ndi kuletsa kuwala kwa UVA, komwe ndi chifukwa chachikulu cha ukalamba wa khungu ndi khansa ya pakhungu. Mankhwalawa ndi othandiza kwambiri pa 320-400 nm, omwe amapereka chitetezo cha UVA chomwe sichingafanane ndi zosakaniza zina zambiri zoteteza ku dzuwa.

Kuwonjezera pa chitetezo chake chabwino cha UVA,Chitetezo ku dzuwa^®DPDT (Disodium Phenyl Dibenzimidazole Tetrasulfonate)yapezeka kuti khungu lake sililowa kwambiri, zomwe zimapangitsa kuti likhale njira yotetezeka komanso yodalirika kwa anthu omwe amasamala za dzuwa. Komanso silitha kujambulidwa mosavuta, zomwe zikutanthauza kuti limagwira ntchito bwino ngakhale litayikidwa padzuwa kwa nthawi yayitali.

Chifukwa cha ntchito yake yodabwitsa,Chitetezo ku dzuwa^®DPDT (Disodium Phenyl Dibenzimidazole Tetrasulfonate)yavomerezedwa kuti igwiritsidwe ntchito mu zodzoladzola zoteteza ku dzuwa m'maiko osiyanasiyana, kuphatikizapo European Union, Japan, ndi United States. Kuphatikizidwa kwake mu zodzoladzola zoteteza ku dzuwa kwawonetsedwa kuti kumawonjezera kwambiri chitetezo cha UVA chonse, kuonetsetsa kuti ogwiritsa ntchito amalandira chitetezo chabwino kwambiri ku kuwala koopsa kwa UV.

Kukwera kwaChitetezo ku dzuwa^®DPDT (Disodium Phenyl Dibenzimidazole Tetrasulfonate)Popeza ndi chinthu chodziwika bwino choteteza khungu ku dzuwa, izi zikusonyeza kuti anthu ambiri akufuna njira zamakono komanso zodalirika zosamalira khungu. Chifukwa cha luso lake lodziteteza bwino ku ukalamba msanga komanso khansa ya pakhungu, likuyembekezeka kukhala maziko a makampani opanga mafuta oteteza khungu ku dzuwa.

Pomaliza,Chitetezo ku dzuwa^®DPDT (Disodium Phenyl Dibenzimidazole Tetrasulfonate)ndi chinthu chosintha kwambiri pa masewera olimbitsa thupi chomwe chimapereka chitetezo cha UVA chosayerekezeka. Pamene kafukufuku wowonjezereka akutsimikizira kugwira ntchito kwake komanso chitetezo chake, akuyembekezeka kukhala chisankho chomwe chimakondedwa ndi opanga mafuta oteteza ku dzuwa ndi ogula omwe.
