Konke okufuneka ukwazi malunga nokukhetha isambulela esichasene ne-UV
Isambrela selanga siyimfuneko ehlotyeni lethu, ingakumbi kubantu aboyikayo ukutshiswa lilanga, kubaluleke kakhulu ukukhetha isambrela selanga esisemgangathweni. Nangona kunjalo, iisambrela azinakwenziwa kuphela ngeendidi ezahlukeneyo zelaphu, kodwa ziza ngemibala eyahlukeneyo kwaye zinemiphumo eyahlukeneyo yokukhusela ilanga. Ngoko ke yeyiphi i-ambrela enemibala elungileyo? Ungayikhetha njani i-ambrela ekhusela ilanga kakhulu? Okulandelayo, ndiza kukunika uhlalutyo lwesayensi lokuba yeyiphi i-ambrela yelanga enemibala eyona ikhusela ilanga, kwaye wabelane ngeengcebiso zendlela yokuthenga i-sun full, jonga.
Ngokweziphumo zovavanyo lwe-Chinese Academy of Measurement Science, umbala welaphu udlala indima ekuthinteleni ilanga le-UV. Okukhona limnyama, kokukhona izinga lokudluliselwa kwe-UV lincinci kwaye kokukhona ukusebenza kokukhusela i-UV kubhetele. Phantsi kweemeko ezifanayo, kokukhona umbala welaphu umnyama, kokukhona ukusebenza kokuchasana ne-UV kubhetele. Xa kuthelekiswa, umnyama
Xa kuthelekiswa, umbala omnyama, onsundu, oluhlaza okotshani kunoluhlaza okwesibhakabhaka, opinki okhanyayo, omthubi okhanyayo, njl. njl. isiphumo se-UV esincinci silungile.
Isambulela selanga: indlela yokukhetha eyona ndlela yokukhusela ilanga
Iiambrela ezinkulu zinokuvala malunga ne-70% yemitha ye-ultraviolet, kodwa azikwazi ukwahlula ipropati ebonakalisiweyo ngaphandle komgca.
Iiambrela eziqhelekileyo zinokuthintela uninzi lwemitha ye-UV, njengoko kukhankanyiwe apha ngasentla, kokukhona umbala weambrela umnyama, kokukhona kungcono. Nangona kunjalo, ukuba ukhetha ilanga elikhulu eline-UV protection coating, kuya kufuneka uqwalasele izinto ezahlukeneyo, ezifana nexabiso, inqanaba lokhuseleko. Ilaphu le-umbrella njalo njalo, ukuze ukwazi ukuthenga iambrela ethembekileyo.
Jonga ixabiso
Ezinye iiambrela zinokugubungela kuphela imisebe yelanga, kwaye imisebe ye-ultraviolet isaza kungena kwilaphu, kuphela emva kokuba unyango lwe-sunscreen coating lube nefuthe lokulwa ne-UV. Ngoko ke, iambrela ayizukukwazi ukukhusela i-UV. Iambrela efanelekileyo, yokukhusela i-UV, ixabiso liyi-yuan ezingama-20 ubuncinane. Ngoko ke chitha iidola ezimbalwa ukuthenga iambrela, ukusebenza kakuhle kokukhusela i-UV kuyathandabuzeka.
Jonga inqanaba lokhuseleko
Kuphela xa ixabiso le-UV protection factor lingaphezulu kwama-30, oko kukuthi i-UPF30+, kwaye izinga lokudluliselwa kwe-UV yamaza amade lingaphantsi kwe-5%, inokubizwa ngokuba ziimveliso zokukhusela i-UV; kwaye xa i-UPF>50, ibonisa ukuba imveliso inokhuselo oluhle kakhulu lwe-UV, uphawu lokhuseleko lwe-UPF50+. Okukhona ixabiso le-UPF likhulu, kokukhona ukusebenza kokhuselo lwe-UV kuphucuka.
