Yonke into ofuna ukuyazi malunga nokukhetha i-anti-Uv Brela
I-Isbrella yelanga kufuneka ihlobo lethu, ngakumbi kubantu abakoyikayo ukuntywila, kubaluleke kakhulu ukukhetha i-Isbrela elungileyo yeLanga. Nangona kunjalo, ayinakuphela kuphela iambrela zenziwe ngeentlobo zeentlobo ezahlukeneyo, kodwa ziza nemibala eyahlukeneyo kwaye zineziphumo ezahlukileyo zelanga kakhulu. Ke leliphi iambrela yombala? Ungayikhetha njani eyona nto ikhuselekileyo ilanga? Okulandelayo, ndiza kukubonelela ngohlalutyo lwesayensi malunga nesambrella yombala elona nkqo ilanga, kwaye wabelane ngeengcebiso malunga nendlela yokuthenga ilanga, jonga.
Ngokwesiphumo sovavanyo lwe-Academy yaseTshayina yeSayensi, umbala welaphu udlale indima kwi-UV Sunbbb. Umnyama ngu, incinci i-UV yenqanaba lokuhambisa u-UV kunye nokusebenza kwe-UV. Ngaphantsi kweemeko ezifanayo, umbala omnyama wendwangu, engcono umsebenzi we-anti-Uv. Ngokuthelekisa, mnyama
Xa kuthelekiswa, mnyama, umkhosi wamanzi, oluhlaza olumnyama kunokukhanya eluhlaza okwesibhakabhaka, ipinki ekhanyayo, ityheli etyheli, njl njl.
I-Isbrella yeLanga yelanga ukuba ukhetha eyona nto ikhulisayo ilanga
Iambrela enkulu inokuthintela malunga ne-70% yemitha ye-ultraviolet, kodwa ayikwazi ukwahlula impahla ebonisiweyo ngaphandle komgca.
I-Iambrela eNjineli inokuthintela uninzi lwee-Uva, njengoko kuchaziwe apha ngasentla, umbala omnyama weambrela, engcono. Nangona kunjalo, ukuba ukhetha ilanga elikhulu ngoKhuseleko lwe-UV, kufuneka uqwalasele izinto ezahlukeneyo, ezinjengexabiso, inqanaba lokhuselo. Indwangu yeambrela, njalo njalo, ukuze uthenge iambrela ethembekileyo.
Jonga ixabiso
Ezinye iiambrela zinokugubungela imitha yelanga kuphela, kwaye imisebe ye-ultraviolet iza kungena kwilaphu, kuphela emva konyango lwelanga kuphela. Ke ayisiyo iambrela iya kuba nakho ukhuseleko. Umyalezo ofanelekileyo, uKhuselo lwe-UV SEBETA, Ixabiso le-20 le-Yuan. Ke chitha iidola ezimbalwa ukuthenga iambrela, ukusebenza ngokukhuselekileyo kwe-UV kuyathandabuza.
Jonga inqanaba lokukhuselwa
Kuphela kuxa ixabiso lezinto eziKhuselo lwe-UV lingaphezulu kwe-30, okt i-DEPF30 + iqondo lokuhambisa ixesha elide lingaphantsi kwe-5%, inokubizwa ngokuba ziimveliso zokukhusela i-UV; Kwaye xa i-UPF> 50, ibonisa ukuba imveliso inomkhuselo obalaseleyo wokukhusela, oKhuselo lwenqanaba lokukhuselwa kwe-UV50 +. Ixabiso elikhulu le-iPF, engcono ukhuseleko lokukhusela i-UV.
IXESHA LOKUQALA: UPE-23 ukuya kwi-2022
