Ukunganyangeki kwe-UV kubhekiselele kuyilo lwemathiriyeli okanye imveliso ukumelana nomonakalo okanye ukucima ngenxa yokuvezwa yimitha yelanga yeultraviolet (UV). Izinto ezixhathisayo ze-UV ziqhele ukusetyenziswa kwiimveliso zangaphandle ezinje ngamalaphu, iiplastiki kunye neengubo zokwaleka ukunceda ukwandisa ubomi nokugcina inkangeleko yemveliso.
Ewe, ezinye iitarp ziyilelwe ngokukodwa ukuba zinganyangeki kwi-UV. Ezi tarp zenziwe ngezinto eziphathwayo ezinokumelana nokuvezwa ixesha elide elangeni ngaphandle kokuwohloka okanye ukulahleka kombala. Nangona kunjalo, kubalulekile ukuqaphela ukuba ayizizo zonke ii-tarp ezixhathisa i-UV kwaye ezinye zinokuhla ngokuhamba kwexesha ukuba zichaneke kukukhanya kwelanga. Xa ukhetha itarp, luluvo olulungileyo ukujonga ileyibhile okanye iinkcukacha zemveliso ukuze uqiniseke ukuba ayinyangeki kwi-UV ukuba oku kubalulekile kusetyenziso olucetywayo.
Umgangatho wokumelana ne-UV ye-tarps ixhomekeke kwizixhobo zabo ezithile kunye ne-UV stabilizers ezisetyenziselwa ukwenziwa kwazo. Ngokubanzi, iitarps ezinganyangekiyo kwi-UV zilinganiswe ngokwepesenti abazivimbayo okanye bafunxa imitha ye-UV. Inkqubo yokulinganisa esetyenziswa ngokuqhelekileyo yi-Ultraviolet Protection Factor (UPF), ekala amalaphu ngokusekelwe kwisakhono sawo sokuthintela imitha ye-UV. Okukhona iphezulu ireyithingi ye-UPF, kokukhona ukhuseleko lwe-UV lungcono. Ngokomzekelo, i-UPF 50-rated block blocks malunga neepesenti ezingama-98 zemitha ye-UV. Nangona kunjalo, kubalulekile ukuqaphela ukuba inqanaba lokwenyani lokunganyangeki kwe-UV linokuxhomekeka kwizinto ezifana nokuba sesichengeni selanga, iimeko zemozulu kunye nomgangatho we-tarp ngokubanzi.
