Zamalonda
1.Kodi Pc zinthu?
PC: polycarbonate, ndi ya thermoplastic material.Izi ndi zowonekera, zachikasu pang'ono, zosavuta kusintha mtundu, zolimba komanso zolimba ndipo mphamvu zake ndizokulirapo, kuwirikiza ka 10 kuposa za CR 39, zida zapamwamba kwambiri za thermoplastic. .Kukhazikika kwabwino kwa kutentha, kutentha kwa kutentha, mpweya ndi ozoni.Imatha kuyamwa kuwala konse kwa ultraviolet pansi pa 385nm, ndikupangitsa kuti ikhale mandala otetezeka.Kuphatikiza pa kukana kutentha kwakukulu, kukana mafuta, mafuta ndi asidi, kuyamwa kwamadzi otsika, kukhazikika kwapamwamba, ndi mtundu wazinthu zoteteza chilengedwe zomwe zingagwiritsidwe ntchito kangapo.Zoipa ndizovuta kwambiri, zosavuta kung'amba, kusokonezeka kochepa ndi ma resins ena, kugundana kwakukulu, palibe kudzipaka mafuta.
2.Zinthu zazikulu zamagalasi a PC:
① kulemera kwa thupi
Ma lens a PC ali ndi mphamvu yokoka ya 1.2, pamene magalasi a CR-39 ali ndi mphamvu yokoka ya 1.32, refractive index 1.56 ili ndi mphamvu yokoka ya 1.28, ndipo galasi ili ndi mphamvu yokoka ya 2.61.Mwachiwonekere, pakati pa mafotokozedwe omwewo ndi kukula kwa geometric kwa mandala, ma lens a PC, chifukwa cha gawo laling'ono kwambiri, amachepetsanso kulemera kwa magalasi.
②magalasi owonda
PC refractive index ndi 1.591, CR-39 (ADC) refractive index ndi 1.499, Middle refractive index ndi 1.553.Mlozera wa refractive ukakhala wapamwamba, magalasi amacheperako, ndipo mosiyana.Poyerekeza ndi magalasi a CR39 ndi ma lens ena a resin, ma lens a PC myopia ndi ochepa kwambiri.
③Chitetezo chapamwamba
Magalasi a PC ali ndi kukana kwabwino kwambiri, komwe kumadziwika kuti "king of pulasitiki", kumatha kugwiritsidwa ntchito kwambiri popanga mazenera oyendetsa ndege, "galasi" lopanda zipolopolo, masks achiwawa ndi zishango.Mphamvu ya PC ndi 87 / kg / cm2, yomwe imaposa zinki ndi aluminiyamu yotayidwa ndipo ndi 12 nthawi ya CR-39.Magalasi opangidwa ndi PC amayikidwa pansi pa simenti kuti ayende ndipo osasweka, ndipo ndi magalasi okhawo "osasweka".Pakadali pano, ma lens a PC ndi achiwiri kwa ena pankhani yachitetezo.
④ kuyamwa kwa cheza cha ultraviolet
Mankhwala amakono atsimikizira kuti kuwala kwa ultraviolet ndiko chifukwa chachikulu cha ng'ala m'maso.Chifukwa chake, zomwe zimafunikira pakuyamwa kwa kuwala kwa ultraviolet kwa magalasi ndizomveka bwino.Kwa magalasi owoneka bwino a utomoni, zinthuzo zimakhalanso ndi gawo la kuyamwa kwa kuwala kwa ultraviolet, koma ngati mukufuna kuteteza kuwala kwa ultraviolet, muyenera kuwonjezera kuchuluka kwa kuwala kwa ultraviolet komwe ma lens a PC myopia amatha 100% kutsekereza ultraviolet. kuwala.
⑤kukana kwanyengo
PC ndi imodzi mwamapulasitiki aumisiri okhala ndi kukana kwanyengo.Malinga ndi kuyesa kwa ukalamba wakunja kwachilengedwe, kulimba kwamphamvu, chifunga ndi zizindikiro za etiolation za PC sizinasinthe kwambiri atayikidwa panja kwa zaka zitatu.
3. Kodi pali kusiyana kotani pakati pa HC, HMC ndi SHC?
| Chophimba cholimba | AR zokutira / zokutira zolimba zambiri | Super hydrophobic zokutira |
| imapangitsa mandala osatsekedwa kukhala olimba ndikuwonjezera kukana kwa abrasion | kumawonjezera kufalikira kwa ma lens ndikuchepetsa mawonekedwe a pamwamba | imapangitsa kuti mandala asalowe madzi, antistatic, anti slip ndi kukana mafuta |
