U-polycarbonate glass uyisibonelo sokubuka njengomkhakha wokubuka? Idatha yokuzimela

Ubukhulu Bekubuka Kwemboni: Ukubala Ubukhulu Bekubuka Kwephulikabonayi I-Glass Nokwesibini I-Glass

Ukuthumela Kwelighayi (%T) Ngemitha Yezinguquko 550 nm: Imboni Yeziphumo Zokuzimisa Kwelaboratori Nokubalwa Kwemibono Yezifundo

Ubukhulu Bekubuka kubhalwa ngokuthumela kwelighayi (%T) ngemitha yezinguquko 550 nm—ukuphakama kokubona kwesibini. Ngokwesifundo sika-ASTM D1003, imboni yezifundo zokubalwa ziyasho:

I-Soda-lime glass iyaphatha ngokuphelele ukuthumela kwe-88–90%, futhi i-polycarbonate yezifundo zokubala iyaphatha ukuthumela kwe-86–88%. Lokhu kucacisa ukuthi kuyasebenza kahle kwezinhlelo ezingenabizo lokubuka—kubantu bokuvimbela kuze kube kwezincwadi zokubonisa. Kodwa %T kuphela akuyiyo inombolo eyodwa yokubala: izinto ezimbili ezenza ukuthumela okufanayo kungathola ubukhulu bekubuka obuhlelwe kakhulu ngokwahlukanisa kwelighayi.

Ubukhulu Bekubuka Kwesibini (Haze) Nobukhulu Bekubuka Kwesibini: Kungani Ukwahlukanisa Kwesibini Kuyisisekelo Esikhulu Kuloko Ukuthumela Okuphakeme %T

Ukukhanya kwezinye izikhathi—kubhekwa njengesilinganisi sezinkampani zokukhanya ezihlukene kunezinkampani zokukhanya ezingaphansi kwe-2.5° kusuka kwezinkampani zokukhanya ezingaphakathi—kubhekwa ngqo njengokugcinwa kwesibonelo. Nangona ukukhanya kwe-polycarbonate kufika emuva kwe-glass, ukukhanya kwe-polycarbonate (1–3%) kakhulu kuneglass (<1%), okuyisiphumo sokukhanya kwezinye izikhathi, okubizwa ngokuthi:

• Ukukhanya kwezinye izikhathi kakhulu ngezikhathi zokukhanya okuphelele okanye okuhambisana ngokuphelele
• Ukuphula kwezinkinga zokubonisa ukuchaza kahle, ikakhulu ngezikhathi zokukhanya okuphelele
• Ukukhanya kwezinye izikhathi okuncane kwezinto eziphakeme kanye nezinto eziphakemene kude

Izibhaca zemboni zemboni, ezitholakala kahle ngezikhathi zokusebenzisa noma ukucima, ziyabusa ukukhanya kwezinye izikhathi kwe-polycarbonate ngokuphelele. Ngaphandle kwe-glass—okwesibonelo sasikhiya esibonelo esisodwa—umkhakha wokusebenza we-polycarbonate owenkulu kakhulu uyakwenzela ukuthi kubhekwe njengokuthi kungafani kakhulu nokukhanya kwezinye izikhathi okuphelele. Ngakho-ke, ukubonisa kahle kufa kahulu nakuba ukukhanya kungabili kahulu.

Ukugcinwa Kwesibonelo Esidlonge: Ukuthi i-polycarbonate glass iyasebenza njani ngemikhakha yezinhlanzi

Ukuthanda kwe-UV nokubhala kwezincwadi: Imiphumela Yokuqondisa Ukuzimisa Kwe-ASTM G154 Yokuqondisa Ukuzimisa Kwe-Polycarbonate Glass

Kodwa uma kungabukelwa, izinkulungwane zezinkampani zezinkampani zizobuka uma zihlukaniswa ngokubuka kwe-UV, kubonakala njengamaphepho amahlanu nezindawo ezingavumelekile ngokuphakade. Ngokwesifundo sokuqondisa kwe-ASTM G154, lezi zinkampani ezingavumelekile zibonisa ukuthuthukisa okubalulekile kwe-Yellowness Index (YI) ngemiphumela yezinkampani ezingu-15 noma ngaphezulu ema-2,000 amahora emaphoyinti. Lokhu kuyisibonelo sokuthi kuzoba kanjani ngomnyaka wokususa ngokuphelele ku-mid latitudes. Lokho okubiza lokuguqula umbala? Ukubuka kwe-UV kubhekisa imikhala yezinkampani futhi kwenza izigaba zezinkampani ezinamakhanda emkhala kusuka kumthwalo wokugcina. Lezi ziguqulo zezinkampani zibeka umkhondo wokubuka kwezinkampani okubonisa ukuthi inkampani ayikwazi ukubuka ngokuvumelekile, ikakhulu kulezi zinkampani zezibhala-nezibhala okufana nokubuka kwezinkampani ezinamakhanda emkhala.

Amathuba okukhetha amakhemikhali e-polycarbonate esikhaleni sokubona manje ayisisekelwa ngamaphuzu okuphatha ukungafani. Abakhi abayisebenzisa amaphuzu o-ko-extruded okuzima izilimi zokubona zokushisa (UV) njengoba ne-technology ya-HALS eyalithola ku-Hindered Amine Light Stabilizers. Ukudluliswa kwezinto zokuphatha kuyasebenza kahle kakhulu, kusinda ukuthi indiza yokuhlanza iyonge ngapansi kwezintandabuzo ezintathu futhi kusinda ukuthi ukufihla kungapansi kwezilinganiso ezimbili ngesikhathi sokugcina isikhathi esingama-10,000 emahholi, okuyizinto ezibalulekile ekubeni ziyasebenza kahle kumazinyo okubuyisa emakhaya noma emaphoyinti okuhamba. Lokhu kuyisho ukuthi kuyasebenza kahle kusasa kuma-5 mna yezinsuku zokusebenza kwizinto ezifana nezinyo zokubuyisa emakhaya noma emaphoyinti okuhamba. Uma kubhekwa kuzinto ozokwenza kuzo ukuthi kubaluleke ukuthi kubhekeke kwezinyo zokubuyisa emakhaya noma emaphoyinti okuhamba, ukuchaza ukuthi kubaluleke ukuthi kubhekeke kwezinyo zokubuyisa emakhaya noma emaphoyinti okuhamba kuyisisekelo esibalulekile kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kusukela kus......

Ukuthintana Kwesikhathi Sokushisa: Ukubona Kuphakeme Ku-–40°C Ukuze +85°C (Amatshe angu-500)

Isivinini sesikhathi sokuphakama kwezinkambu zokugqibela (CTE) se-polycarbonate siyisikhathi esisigcwele esingaphezu kwe-glass, okwenza ukuthi kubhekwa ngokukhula kwezinkambu zokugqibela futhi kuzokwenzeka ukuguqula kwesibonelo ngokuphakama nokuphupha kwesikhathi. Kukuphakamisa kwezinkambu zokugqibela ezingaphezu kwe-500 kusuka ku-–40°C ku-+85°C:

• I-polycarbonate eya kufakwa ngokufakwa kwezinkambu zokugqibela nezinkambu eziningi ziyabonisa ukuphakama kwe-haze ngaphezu kwe-1.5% futhi ukuphakama kwe-transmission kungaphezu kwe-3%
• Izinhlobo ezingatholakali kuzo ziyaphila ukuphakama kwe-transmission ngaphezu kwe-12% futhi izinkambu zokugqibela ziyabonakala ngokuvamile

Izinhlobo zezinkambu zokugqibela eziphakeme ziyasindisa ukuguqula ngokulandela i-CTE ngokudlula izinkambu zokugqibela futhi ngokuhlela ukuxhuma phakathi kwezinkambu. Lokhu kusinda ukubonakala kwezinto kwezinkambu zokugqibela zase-automotive HUDs, izinkambu zokugqibela zase-aerospace sensor, nezinkambu zokugqibela zase-industrial machine vision systems—lapho ukuguqula kungaphezu kwe-0.3% kungahleli ukubaluleka kokubaluleka kokubaluleka kokubaluleka.

Ukubonakala Kwemisebenzi: Isivinini Sesikhathi Sokubonakala, Ukuguqula, Nokusebenza Kwempilo Kwezinkambu Zokugqibela Zase-Glass

Ukulingana Kwe-Refractive Index Futhi Ukuhlukana Kwalo Kuyakubangela Ukubonakala Kwemithambo, Ukubonakala Kwemithambo, Nokubonakala Kwesibonelo

Indeksu yokubuka kwe-polycarbonate (ngokwesibonelo kusuka ku-1.58 ku-1.59) kuyisikhulu kune-glass yezinkolelo zokuphakama ephakamileyo eyodwa ngokwesibonelo ku-1.52. Lokhu kuchitha izinkinga zokubuka ezibonakalayo lapho ilight ibuyela phakathi kwe-air nezinye zemifulo yomfanekiso noma phakathi kwezinye izilayi. Lokhu kufisa ukuthi lezi zinkinga zizoba zingakhulu kakhulu ngoba lezi zifaniswe zingathatha i-Fresnel reflection losses ngaphezu kwe-8 percent, okuvula izinkinga zokubuka kwe-glare ozobukhona kakhulu okuzokwenza ukuthi kube nzima ukufunda amaphuzu emboni phezu kwe-dashboards yezimotokhari noma emabhangeni apho ilight yezinkolelo iyadlula. Lapho sibheka izindlela ezingabi ngezinye njenge-security glass enezilayi noma amadisplay anezifunctionality zokuclicka, lezi zibonakalo zangaphakathi ziyadlala kakhulu. Kuzoba kanjani? Ukuchitha kwesibonelo kushushiswa kakhulu futhi izibonakalo zezikhalo zingafana zingadlala, okuzokwenza konke kube mncane kakhulu nokubonakala ngokungabi nesifundo.

Ukuthanda kwe-refractive index okuphakathi kuyakwenza lezi ziququsho zemithambo ezingaphansi kahle xa kusebenziswa izinyathelo ezihlukene noma ezenzima. Bona izinyathelo zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye zezinye......
