Khoom nta
1.Cov khoom siv PC yog dab tsi?
PC: polycarbonate, belongs rau cov khoom siv thermoplastic.Cov khoom no yog pob tshab, me ntsis daj, tsis yooj yim los hloov xim, nruj thiab tawv thiab nws lub zog muaj zog tshwj xeeb, ntau dua 10 npaug ntawm CR 39, saum toj kawg nkaus ntawm cov ntaub ntawv thermoplastic. .Zoo stability rau cua sov, thermal tawg, huab cua thiab ozone.Nws tuaj yeem nqus tau tag nrho cov kab hluav taws xob ultraviolet hauv qab 385nm, ua rau nws lub lens muaj kev nyab xeeb.Ntxiv nrog rau kev kub siab ua haujlwm, roj tsis kam, roj thiab kua qaub, tsis muaj dej nqus, qib siab ntawm qhov ruaj khov, nws yog ib yam khoom siv tiv thaiv ib puag ncig uas tuaj yeem siv suav tsis tau.Qhov tsis zoo yog kev ntxhov siab loj, yooj yim rau tawg, tsis muaj miscibility nrog lwm cov resins, kev sib txhuam coefficient siab, tsis muaj nws tus kheej lubrication.
2.Lub ntsiab nta ntawm PC lens:
① Lub teeb yuag
PC lo ntsiab muag muaj lub ntiajteb txawj nqus ntawm 1.2, thaum CR-39 lo ntsiab muag muaj lub ntiajteb txawj nqus ntawm 1.32, refractive index 1.56 muaj lub ntiajteb txawj nqus ntawm 1.28, thiab iav muaj lub ntiajteb txawj nqus ntawm 2.61.Obviously, ntawm tib yam specifications thiab geometric loj ntawm lub lens, PC lo ntsiab muag, vim qhov tsawg tshaj plaws kev faib ua feem, ntxiv txo qhov hnyav ntawm lo ntsiab muag.
② nyias lens
PC refractive index yog 1.591, CR-39 (ADC) refractive index yog 1.499, Middle refractive index yog 1.553.Qhov siab dua qhov refractive index yog, lub thinner lub lo ntsiab muag yog, thiab vice versa.Piv nrog CR39 lo ntsiab muag thiab lwm yam lo ntsiab muag resin, PC myopia lo ntsiab muag ntug yog qhov nyias nyias.
③ Kev ruaj ntseg zoo heev
PC lens muaj qhov cuam tshuam zoo heev, lub npe hu ua "tus huab tais ntawm yas", tuaj yeem siv dav hauv kev tsim cov qhov rais aviation, mos txwv "iav", lub qhov ncauj qhov ntswg thiab cov ntaub thaiv npog.Qhov cuam tshuam lub zog ntawm PC yog txog li 87 / kg / cm2, uas tshaj li ntawm cam khwb cia zinc thiab cam khwb cia txhuas thiab yog 12 npaug ntawm CR-39.Cov lo ntsiab muag ua los ntawm PC yog muab tso rau hauv cov cement hauv av kom tsis txhob tawg, thiab tsuas yog "tsis tawg" lo ntsiab muag.Txog tam sim no, PC lo ntsiab muag yog qhov thib ob rau qhov tsis muaj kev nyab xeeb.
④ absorption ntawm ultraviolet rays
Cov tshuaj niaj hnub tau lees paub tias lub teeb ultraviolet yog qhov ua rau mob cataracts hauv qhov muag.Yog li ntawd, qhov yuav tsum tau ua rau ultraviolet lub teeb nqus ntawm lo ntsiab muag yog ntau dua thiab meej.Rau cov khoom siv kho qhov muag dav dav, cov khoom siv nws tus kheej kuj muaj ib feem ntawm kev ua haujlwm ntawm ultraviolet lub teeb nqus, tab sis yog tias koj xav kom tiv thaiv lub teeb ci ultraviolet los ntawm, koj yuav tsum ntxiv qee qhov ntawm ultraviolet lub teeb absorbent thaum PC myopia lo ntsiab muag tuaj yeem 100% thaiv ultraviolet. teeb.
⑤ huab cua tsis zoo
PC yog ib qho ntawm cov yas engineering nrog cov huab cua zoo heev.Raws li kev sim cov ntaub ntawv ntawm kev laus sab nraum zoov, lub zog tensile, haze thiab etiolation qhia ntawm PC tsis hloov ntau tom qab muab tso rau sab nraum zoov rau 3 xyoos.
3. Qhov txawv ntawm HC, HMC thiab SHC yog dab tsi?
Txheej tawv | AR txheej / Hard txheej txheej | Super hydrophobic txheej |
ua rau lub lens uncoated nyuaj thiab tsub kom lub abrasion kuj | tsub kom lub transmittance ntawm lub lens thiab txo cov reflections nto | ua rau lub lens waterproof, antistatic, anti plam thiab roj kuj |
