Yonke into ekufuneka uyazi malunga nokukhetha iambrela echasene ne-UV elungileyo
I-ambrela yelanga iyimfuneko ehlotyeni lethu, ngakumbi kubantu aboyika ukutshisa, kubaluleke kakhulu ukukhetha i-ambrela yelanga esemgangathweni.Nangona kunjalo, i-ambrela ayinakwenziwa kuphela kwiintlobo ezahlukeneyo zeendwangu, kodwa nazo ziza ngemibala eyahlukeneyo kwaye zineempembelelo zokukhusela ilanga.Ngoko ngowuphi umbala weambrela elungileyo?Indlela yokukhetha i-ambrela yokukhusela ilanga?Okulandelayo, ndiza kukunika uhlalutyo lwenzululwazi ukuba yeyiphi umbala iambrela yelanga yeyona nto ikhusela ilanga, kwaye wabelane ngeengcebiso malunga nendlela yokuthenga ilanga eligcweleyo, jonga.
Ngokweziphumo zovavanyo lwe-China Academy of Measurement Science, umbala welaphu nawo udlala indima kwibhlokhi yelanga ye-UV.Okukhona kumnyama, kokukhona kuncinci izinga losulelo lwe-UV kunye nokusebenza ngcono kokhuseleko lwe-UV.Phantsi kweemeko ezifanayo, umbala omnyama welaphu, ngcono ukusebenza kwe-anti-UV.Ngokuthelekisa, abamnyama
Xa kuthelekiswa, emnyama, navy, eluhlaza okwesibhakabhaka kunokukhanya blue, pink ukukhanya, tyheli ukukhanya, njl umngxuma UV effect ilungile.
I-ambrella yelanga indlela yokukhetha ukhuseleko lwelanga kakhulu
Iiambrela ezinkulu zinokuvala malunga ne-70% yemitha ye-ultraviolet, kodwa ayikwazi ukuhlukanisa ipropati ebonakalisiweyo ngaphandle komgca.
Iiambrela ngokubanzi zinokuvalela ngaphandle imitha ye-UV, njengoko kukhankanyiwe ngasentla, umbala weambrela umnyama, ungcono.Nangona kunjalo, ukuba ukhetha ilanga elikhulu kunye ne-UV yokukhusela i-UV, kufuneka uqwalasele izinto ezahlukeneyo, njengexabiso, izinga lokukhusela.Ilaphu le-umbrella kunye nokunye, ukwenzela ukuba uthenge i-ambulera ethembekileyo.
Jonga ixabiso
Ezinye iiambrela zinokugubungela kuphela imitha yelanga, kwaye imitha ye-ultraviolet iya kuhlala ingena kwilaphu, kuphela emva kokuba unyango lokugquma kwe-sunscreen lube nefuthe le-anti-UV.Ke ayisiyiyo iambrela iya kukwazi ukhuseleko lwe-UV.I-umbrella eqinisekisiweyo, i-UV yokukhusela, ixabiso le-yuan engama-20 ubuncinane.Ke uchithe iidola ezimbalwa ukuthenga iambrela, ukusebenza kokhuselo lwe-UV kuyathandabuzeka.
Jonga kwinqanaba lokhuseleko
Kuphela xa ixabiso lokukhusela i-UV lingaphezulu kwe-30, oko kukuthi i-UPF30 +, kunye nesantya sokuhanjiswa kwe-UV emide ingaphantsi kwe-5%, inokubizwa ngokuba yimveliso yokukhusela i-UV;kwaye xa i-UPF>50, ibonisa ukuba imveliso inokhuseleko oluhle kakhulu lwe-UV, umgangatho wokukhusela uphawu lwe-UPF50 +.Ixabiso elikhulu le-UPF, ngcono ukusebenza kokhuselo lwe-UV.
