Izimpawu Zezindwangu Zokuvikela Ilanga Ezivuleleka Okuhlukile

Izici zezindwangu ze-sunscreen ezinokuvuleka okuhlukile

Isilinganiso se-open-hole isilinganiso sezimbobo ezincane ezihlanganiswe yi-warp nentambo ye-weft yendwangu ye-sunshade.Ukuthungwa okufanayo kwalukwa ngemicu yombala nobubanzi obufanayo, futhi ikhono lokuvimba ukushisa okukhazimulayo kwelanga nokulawula ukuxhopha ngesilinganiso esincane sokuvula kunamandla kunesilinganiso esikhulu sokuvula.

1. Izindwangu ezinezinga lokuvula elingu-1% kuya ku-3% zingavimba ukushisa okukhiqizwa imisebe yelanga ngezinga elikhulu kakhulu futhi zilawule ukuxhopha, kodwa ukukhanya kwemvelo kuzongena kancane futhi umphumela wokubonisa ngale uphansi kakhulu.Ngakho-ke, ngokuvamile siphakamisa ukuthi siyisebenzise kwezinye izikhombisi-ndlela ezikhanyiswe yilanga (njengaseningizimu-ntshonalanga), futhi lapho udonga lwamakhethini lwenziwe ngengilazi esobala, ukuxazulula inkinga yokushisa okukhulu kwemisebe nokukhanya kwelanga okukhazimulayo.

2. Indwangu ene-porosity evulekile engu-10% ingathola ukukhanya okuhle kwemvelo nokungafihli, kodwa ukumelana kwayo nemisebe yelanga kanye ne-glare kubi kakhulu.Ngokuvamile sincoma ukusetshenziswa kwezindwangu ezivulekayo ezingu-10% kwezinye izikhombisi-ndlela zokuchayeka elangeni (njengasenyakatho), futhi sisebenzise kwezinye izindonga zamakhethini ezingilazi ezinemibala ukuze sithole ukukhanya kwemvelo okungcono kakhulu nokungafihli lutho.

I-3.5% isetshenziswa kabanzi.Isebenza kahle ekuvimbeni imisebe yelanga, ukulawula ukukhanya, nokuthola ukukhanya kwemvelo nokungafihli kahle.Ngokuvamile sincoma ukuthi ingasetshenziswa eningizimu.
