1. Iyini ilensi ye-PC?
I-PC iwukusebenza kahle kwamapulasitiki obunjiniyela be-thermoplastic, amapulasitiki wobunjiniyela amahlanu ngaphakathi kokungafihli kahle komkhiqizo, kodwa futhi eminyakeni yamuva nje ukukhula okusheshayo kwamapulasitiki obunjiniyela ajwayelekile.Njengamanje, isetshenziswa kabanzi ku-optics, electronics, architecture, imoto, ukunakekelwa kwezempilo kanye neminye imikhakha, ikakhulukazi ukukhiqizwa kwezibuko zamehlo.

2. Kungani zibizwa ngamalensi asemkhathini?
I-POLYCARBONATE(PC) iwumsebenzi owenziwe ososayensi ukuze benze imishini yokuhlola umkhathi ifanele indawo ekhethekile yendawo, ngakho-ke yaziwa kakhulu ngokuthi ilensi yasemkhathini.

3. Yini enhle ngayo?
Izinto ze-PC zinezinzuzo ze-Ultra-zacile, ukukhanya okukhanyayo, ukumelana nokushayisana okuphezulu, ukuvikelwa kwe-UV kanye nokudluliswa kahle kokukhanya, isetshenziswa kabanzi kumapulasitiki wobunjiniyela izinto ezibonakalayo, Inokuqina okuhle futhi akukho conductivity kagesi, ngakho-ke uhla lwesicelo lubanzi kakhulu, futhi lwenziwe ngemvelo yelensi ye-PC enezinzuzo ezingenhla, ikakhulukazi ifanele inombolo ephezulu, igqoke njengezingane ezinhle, izingane ezineminyaka engaphansi kwe-United States yezemidlalo, izingane ezineminyaka engaphansi kwe-1. 3 kumele ifake amalensi e-PC.
Amalensi e-resin evamile ayizinto eziqinile ezishisayo, okungukuthi, izinto ezingavuthiwe ziwuketshezi, zishisiswe ukuze zakhe amalensi aqinile.I-PC piece iyimpahla ye-thermoplastic, okungukuthi, impahla eluhlaza iqinile, ngemva kokushisa, ukubunjwa kwe-lens, ngakho-ke lo mkhiqizo we-lens uzobe ushintshashintsha ngokweqile, awufaneleki umswakama ophezulu kanye nezikhathi zokushisa.Ilensi ye-PC inokuqina okuqinile, ayiphukile (2cm ingasetshenziselwa ingilazi engangenwa izinhlamvu), ngakho ibizwa nangokuthi ilensi yokuphepha.Amandla adonsela phansi athile amagremu angu-2 kuphela cubic centimitha ngayinye, okwenza kube yinto elula kunazo zonke esetshenziselwa amalensi okwamanje.Umkhiqizi wamalensi e-PC uyi-Esilu ehamba phambili emhlabeni, izinzuzo zayo zibonakala ekwelashweni kwe-lens aspheric kanye nokwelashwa okuqinisayo.
Amalensi esikhala e-PC enziwe ngamalensi e-polycarbonate, futhi amalensi eresin evamile (CR-39) anomehluko obalulekile!I-PC ijwayele ukubizwa ngokuthi ingilazi engangenwa izinhlamvu, ngakho-ke amalensi e-PC anamathela ezicini ezinhle kakhulu zezinto ezingavuthiwe ukumelana nomthelela omkhulu, futhi ngenxa yenkomba ephezulu ye-refractive nesisindo esilula, anciphisa kakhulu isisindo se-lens, kunezinzuzo ezengeziwe ezinjengokuthi: 100% ukuvikelwa kwe-UV, iminyaka engu-3-5 ngeke ibe phuzi.Uma kungekho nkinga kule nqubo, isisindo silula ngo-37% kuneshidi le-resin evamile, futhi ukumelana nomthelela kufika izikhathi ezingu-12 ze-resin evamile!

4. Umlando wamalensi e-PC
Ngo-1957,
Inkampani yaseMelika iGE(General Electric) yahola ekuthuthukisweni kwe-PC(polycarbonate) plastic, futhi yabiza iLexan.Inkampani yaseJalimane iBayer ilandele ne-PC yabo ipulasitiki iMakrolen.
Ngawo-1960
Ikhulu lesibili laphela.I-PPG iguqule i-CR-39 resin material kusukela kwezempi ukuze yenze amalensi azosetshenziswa abantu.
Ngawo-1970
Ekuqaleni kwawo-1970, iziguli zaqala ukuthola amalensi e-CR-39.
Ngo-1973,
85% amalensi engilazi kanye namalensi angu-15% CR-39.
Ngo-1978,
Ngenzuzo yamaphrojekthi wezempi kanye ne-aerospace, iGentex yaqala ukusebenzisa i-PC ukwenza amalensi okuphepha.
Ngo-1979,
Emazweni athuthukile, i-lens material iyaguqulwa isuka engilazini iye ku-CR-39 resin.Iqeda ukubusa kweminyaka ecishe ibe ngu-600 yelensi yengilazi.
Ngo-1985,
I-Vision-eaase Lenses Inc. isungule ukwethulwa kwamalensi e-PC kadokotela.
Ngo-1991,
I-Transitions, Inc. ikhipha isizukulwane sokuqala samalensi e-resin ashintsha umbala.
Ngo-1994,
Amalensi e-PC enza i-10% yemakethe yase-US.
Ngo-1995,
Ilensi ye-PC ehlukanisayo yazalwa.
Ngo-2002,
Amalensi e-PC enza ama-35% emakethe yase-US, kuyilapho amalensi engilazi enza ngaphansi kuka-3%.
