Izici Zomkhiqizo
1.Iyini impahla ye-Pc?
I-PC: i-polycarbonate, ingeye-thermoplastic material.Le nto isobala, iphuzi kancane, akulula ukuyishintsha umbala, iqinile futhi iqinile futhi amandla ayo okuthinta makhulu kakhulu, izikhathi ezingaphezu kwezingu-10 kunalezo ze-CR 39, ezikleliswe phezulu ezintweni ze-thermoplastic. .Ukuzinza okuhle ekushiseni, emisebeni eshisayo, emoyeni kanye ne-ozone.Ingakwazi ukumunca yonke imisebe ye-ultraviolet engaphansi kuka-385nm, iyenze ibe ilensi ephephile.Ngaphezu kokumelana nokushisa okuphezulu, ukumelana nowoyela, amafutha kanye ne-asidi, ukumuncwa kwamanzi aphansi, izinga eliphakeme lokuzinza kwe-dimensional, kuwuhlobo lwempahla yokuvikela imvelo engasetshenziswa izikhathi ezingenakubalwa.Ukungalungi ukucindezeleka okukhulu, ukuqhekeka kalula, ukuxubeka okuphansi namanye ama-resin, i-coefficient ephezulu ye-friction, akukho-lubrication self.
2.Izici eziyinhloko zamalensi e-PC:
① isisindo esilula
Amalensi e-PC anomthamo othize we-1.2, kuyilapho amalensi e-CR-39 enomthamo othize we-1.32, inkomba ye-refractive 1.56 inomthamo othize we-1.28, futhi ingilazi inomthamo othize we-2.61.Ngokusobala, phakathi kokucaciswa okufanayo nosayizi wejometri welensi, amalensi e-PC, ngenxa yengxenye encane kakhulu, anciphisa kakhulu isisindo samalensi.
②amalensi azacile
I-PC refractive index ingu-1.591, CR-39 (ADC) refractive index yi-1.499, Middle refractive index yi-1.553.Uma inkomba ye-refractive iphakeme, ama-lens aba mancane, futhi ngokuphambene nalokho.Uma kuqhathaniswa namalensi e-CR39 namanye amalensi e-resin, unqenqema lwamalensi e-PC myopia mancane kakhulu.
③Ukuvikeleka okuhle kakhulu
Ilensi ye-PC inokumelana nomthelela omuhle kakhulu, owaziwa ngokuthi "inkosi yepulasitiki", ingasetshenziswa kabanzi ekwenzeni amafasitela endiza, "ingilazi" engangenwa izinhlamvu, imaski nezihlangu.Amandla omthelela we-PC afika ku-87/kg/cm2, adlula awe-cast zinc ne-aluminium ephonswe futhi aphindwe izikhathi ezingu-12 kunawe-CR-39.Amalensi enziwe yi-PC afakwa esihlabathini sikasimende ukuze anyathele futhi awaphukile, futhi yiwo kuphela amalensi "angaphukile".Kuze kube manje, amalensi e-PC angeyesibili kwanoma yiliphi mayelana nokuphepha.
④ukumuncwa kwemisebe ye-ultraviolet
Imithi yesimanje isiqinisekisile ukuthi ukukhanya kwe-ultraviolet kuyimbangela eyinhloko ye-cataracts emehlweni.Ngakho-ke, izidingo zokumuncwa kokukhanya kwe-ultraviolet kwamalensi zicace kakhulu.Kumalensi ajwayelekile e-resin optical, impahla ngokwayo nayo inengxenye yokusebenza kokumuncwa kokukhanya kwe-ultraviolet, kodwa uma ufuna ukuvikela ngempumelelo ukukhanya kwe-ultraviolet, kufanele wengeze inani elithile lokumunca ukukhanya kwe-ultraviolet kuyilapho amalensi e-PC myopia akwazi ukuvimba i-ultraviolet ngo-100%. ukukhanya.
⑤ukumelana nesimo sezulu esihle
I-PC ingenye yepulasitiki yobunjiniyela enokumelana nesimo sezulu esihle kakhulu.Ngokusho kwedatha yokuhlola yokuguga kwemvelo yangaphandle, amandla aqinile, inkungu kanye nezinkomba ze-etiolation ze-PC azishintshanga kakhulu ngemva kokubekwa ngaphandle iminyaka engu-3.
3. Uyini umehluko phakathi kwe-HC, HMC ne-SHC?
| Ukugqoka okuqinile | I-AR coating / Hard multi coating | I-Super hydrophobic coating |
| yenza ilensi engamboziwe ibe lukhuni futhi ikhulise ukumelana nemihuzuko | kwandisa ukudluliswa kwe-lens futhi kunciphisa ukubonakaliswa kwendawo | yenza i-lens ingangeni manzi, i-antistatic, i-anti slip kanye nokumelana nowoyela |
