Uyabazi ubudlelwano phakathi kweshidi lePolycarbonate kanye Nokuvikelwa Emisebeni ye-UV?
Ukusetshenziswa kwamashidi e-polycarbonate ophahleni sekucishe kwafana nokuvikelwa emisebeni ye-UV. Kodwa sisho ukuthini ngempela lesi sivikelo? Futhi yini isivikelo esihle?
Iyini imisebe ye-ultraviolet?
Imisebe ye-Ultraviolet (UV) iwuhlobo lwemisebe kagesi ebonakala ngokuvama kwayo okuphezulu kanye nobude begagasi obufushane uma kuqhathaniswa nokukhanya okubonakalayo. Iwela ngaphandle kobubanzi bokukhanya okubonakalayo ku-spectrum ye-electromagnetic. Imisebe ye-UV ikhishwa yilanga nemithombo yokwenziwa ehlukahlukene, njengezibani zokushuka nama-welding arcs.
Kunezinhlobo ezintathu eziyinhloko zemisebe ye-UV, ngayinye enamaza ahlukene kanye nezakhiwo:
I-UV Spectrum Blocking: I-Polycarbonate ivimba cishe wonke ama-spectrum e-UV afanelekile, okuhlanganisa kokubili imisebe ye-UVA ne-UVB. Imunca imisebe ye-UV futhi ayikuvumeli ukuba idluliselwe kuyo.
Ukubaluleka Kokuvikela I-UV: Imisebe ye-UV ingaba nemiphumela eyingozi kubantu nasezintweni ezingaphili. Ukuchayeka kakhulu emisebeni ye-UV kungandisa amathuba okuba nomdlavuza wesikhumba, kubangele ukushiswa yilanga, ukuguga kwesikhumba ngaphambi kwesikhathi, nokulimala kwamehlo.
I-UVA (320-400 nm): I-UVA inobude beza obude kakhulu phakathi kwezinhlobo ezintathu zemisebe ye-UV. Ivamise ukubizwa nge-"long-wave" UV futhi inamandla amancane. Imisebe ye-UVA ingangena esikhunjeni ijule futhi inesibopho sokubangela ukuguga kwesikhumba ngaphambi kwesikhathi, imibimbi, futhi ingaba nomthelela ekukhuleni komdlavuza wesikhumba.
I-UVB (280-320 nm): I-UVB iyi-wavelength emaphakathi futhi ivamise ukubizwa ngokuthi i-UV "igagasi elimaphakathi". Inamandla kakhulu kune-UVA futhi ingabangela ukushiswa yilanga, ukulimala kwe-DNA, futhi ibe nomthelela ekukhuleni komdlavuza wesikhumba. Nokho, imisebe ye-UVB nayo iyadingeka ukuze kukhiqizwe uvithamini D esikhumbeni.
I-UVC (100-280 nm): I-UVC inobude beza obufushane kakhulu futhi inamandla kakhulu ezinhlotsheni ezintathu. Ngenhlanhla, cishe yonke imisebe ye-UVC imuncwa umkhathi woMhlaba futhi ayifinyeleli phezulu. I-UVC ilimaza kakhulu izinto eziphilayo futhi ivame ukusetshenziselwa izinjongo zokubulala amagciwane ezindaweni ezilawulwayo.
Ukuchayeka emisebeni ye-UV, ikakhulukazi ukuchayeka ngokweqile nokungavikelekile, kungaba nemiphumela eyingozi ezintweni eziphilayo. Kubantu, kungaholela ekulimaleni kwesikhumba, ezinkingeni zamehlo (njenge-cataract), kanye nengozi eyengeziwe yomdlavuza wesikhumba. Imisebe ye-UV nayo iyisici esibalulekile ekonakalisweni kwezinto nezindawo ezichayeka elangeni, njengezindwangu, amapulasitiki nopende.
Ukuze uzivikele emiphumeleni eyingozi yemisebe ye-UV, kubalulekile ukusebenzisa isikrini selanga esinokuvikela okubanzi, ukugqoka izingubo zokuzivikela nezibuko zelanga, futhi ugweme ukuchayeka kakhulu elangeni, ikakhulukazi phakathi namahora okukhanya kwelanga aphakeme kakhulu.
Ingabe ishidi le-polycarbonate livimba imisebe ye-UV?
Yebo, i-polycarbonate yaziwa ngamandla ayo okuvimba imisebe ye-UV ngokwezinga elithile. Amashidi e-polycarbonate avame ukusetshenziswa ezinhlelweni lapho ukuvikela kwe-UV kubalulekile, njengasezisithobeni, ukukhanya kwesibhakabhaka, amaphaneli abamba ukushisa, nezingubo zamehlo ezivikelayo. Kodwa-ke, izinga lokuvikelwa kwe-UV elihlinzekwa yi-polycarbonate lingahluka ngokusekelwe ekwakhiweni okuqondile kwento kanye nanoma yiziphi ezinye izimbotshana ezingase zisetshenziswe.
Ishidi le-Polycarbonate I-UV Resistance: I-Polycarbonate inokwemvelo ukumelana ne-UV futhi ingavimba yomibili imisebe ye-UVA ne-UVB ngokumunca imisebe futhi iyivimbele ukuthi ingadluliswa. Eqinisweni, i-polycarbonate inganikeza ukuvikeleka okungcono emisebeni ye-UV kunamanye amakhilimu avimbela ilanga.
Ukuvikelwa Kwezinto Ezingaphili: Ukumelana ne-UV ye-Polycarbonate akubalulekile nje kuphela ekuvikelweni komuntu kodwa futhi nasekulondolozeni ubuqotho nokuphila isikhathi eside kwempahla ngokwayo. Ngaphandle kokuvikelwa okufanele kwe-UV, amashidi e-polycarbonate angashintsha umbala futhi abe buthakathaka ngokuhamba kwesikhathi.
I-Protective Coating: Ukuthuthukisa ukumelana kwe-UV kwamashidi e-polycarbonate, abakhiqizi bavame ukusebenzisa i-coat yokuzivikela emincane. Lokhu kunamathela kuvikela i-polycarbonate ekushintsheni umbala nasekuphuzini okubangelwa ukuchayeka kwe-UV, iqinisekisa ukuthi impahla igcina ukucaca nokusebenza kwayo.
Izicelo: I-Polycarbonate enokuvikelwa kwe-UV ivamise ukusetshenziswa ezinhlelweni ezihlukahlukene lapho kudingeka khona kokubili ukuqina nokumelana ne-UV. Lokhu kuhlanganisa izakhiwo zangaphandle ezifana nokufulela, ukukhanya kwesibhakabhaka, izindlu zokugcina izithombo, namakhava okuvikela amachibi okubhukuda.
Kubalulekile ukuqaphela ukuthi nakuba i-polycarbonate inikeza isivikelo se-UV, kusekuhle ukuthi kuthathwe izinyathelo ezengeziwe zokuvikela ilanga, njengokugqoka i-sunscreen nezingubo zokuzivikela, ikakhulukazi uma uchitha isikhathi eside ungaphandle.
Abakhiqizi bavame ukuthuthukisa ukuvikeleka kwe-UV kwamashidi e-polycarbonate ngokungeza iziqinisi ze-UV noma ama-coatings phakathi nenqubo yokukhiqiza. Lezi zengezo zisiza ukunweba ubude bempilo bezinto ngokunciphisa ukuwohloka nokubaphuzi okubangelwa ukuchayeka kwe-UV. Angaphinde anikeze ukuvikeleka okuthuthukisiwe kuyo yomibili imisebe ye-UVA ne-UVB.
Uma ucabanga ukusebenzisa i-polycarbonate ezinhlelweni ezidinga ukuvikeleka kwe-UV okubalulekile, okufana nesisitho selanga noma amaphaneli abamba ukushisa, kuwumqondo omuhle ukukhetha amashidi e-polycarbonate aklanyelwe ngokukhethekile ukunikeza ukumelana ne-UV okuthuthukisiwe. Lawa mashidi alebulwe ngokuthi "Avikelwe nge-UV" noma "afakwe nge-UV" futhi akhiwe ukuze anikeze ukusebenza okungcono kwesikhathi eside ezindaweni ezingaphandle.
Ekugcineni, uma ukuvikela kwe-UV kuwukukhathazeka okuyinhloko, kunconywa ukuthi uxhumane nomkhiqizi noma umphakeli ukuze uqinisekise ukuthi ukhetha
Isiphetho
Ngokwengqikithi ye-polycarbonate nendima yayo ekuvikeleni emisebeni ye-ultraviolet, kubalulekile ukuqaphela izinhlobo ezimbili ezihlukene zokuvikela. Isendlalelo sokuqala sokuvikela sithinta labo abangaphansi kophahla lwe-polycarbonate – kokubili abantu nempahla. Kungakhathaleki izici ezithile ezifana nokwakheka, ukujiya, noma umbala, wonke amashidi e-polycarbonate anikeza ngokwemvelo lokhu kuzivikela emisebeni ye-UV eyingozi. Le nzuzo ye-polycarbonate ngaphezu kwezinye izinto ezikhanyayo iyaphawuleka ngempela. Isici sesibili sokuvikela siphathelene nokulondolozwa kweshidi ngokwalo, liqinisekisa izinzuzo zalo ezihlala njalo nezici. Uma ukhetha ukufaka lawa mashidi ngaphandle, kubalulekile ukubeka phambili ukwelashwa kokuvikela kwe-UV kwekhwalithi ephezulu ukuze uvikele ukuphila kwawo isikhathi eside ngempumelelo.
