Iambrela yemozulu yonke ikhusela ilanga.Zininzi iiambrela ezisongayo, nokuba imvula okanye ilanga ingasetyenziswa.Ke, ngaba kukho ingozi ekusebenziseni iambrela yemozulu yonke?Ngokuqhelekileyo akunjalo.
Isitshixo sokhuselo lwe-UV luxhomekeke kwilaphu le-ambrela liphathwa nge-UV.Ukhuseleko lwe-UV lwanele.Ngokuchasene noko, umphumo umbi.Nangona kunjalo, kukho iimeko ezikhethekileyo.Ngokomzekelo, nangona kungekho unyango lwe-UV, kukho i-vinyl.Kodwa i-anti-ultraviolet impembelelo yayo iphezulu kwiimveliso eziqhelekileyo.Ukuba ilaphu lisemgangathweni olungileyo, isalathisi se-UV sinokufikelela kwi-600 + kwaye izinga lomthunzi liphantse libe yi-100%.Xa uthatha iambrela, yivule ukuze ujonge izithunzi ezisemhlabeni.Amathunzi amnyama ngakumbi.Kuphela ukuba i-UPF (ixabiso lokukhusela i-ultraviolet) ingaphezulu kwe-30 kwaye ukuhanjiswa kwe-UVA (UVA) kungaphantsi kwe-5% kunokubizwa ngokuba yimveliso echasene ne-UV.Umgangatho wokhuseleko "UPF30 +";Xa i-UPF inkulu kune-50, ibonisa ukuba imveliso inokhuseleko oluhle kakhulu lwe-UV.Inqanaba lokukhusela liphawulwe njenge "UPF50 +".
