Chiwonetsero cha Shanghai International Eyewear Exhibition (Shanghai Eyewear Exhibition, International Eyewear Exhibition) ndi imodzi mwamakampani akuluakulu komanso ovomerezeka padziko lonse lapansi opanga zovala zapamaso komanso ziwonetsero zamalonda ku China, komanso ndiwonetsero yapadziko lonse lapansi ya zovala zokhala ndi mitundu yotchuka ku Asia.
Chiwonetsero cha Shanghai International Eyewear Exhibition (Shanghai Eyewear Exhibition, International Eyewear Exhibition) chinachitika m'maholo onse anayi omwe ali mkati mwa Shanghai World Expo Exhibition Hall. Malo owonetserako ndi malo oyambirira a 2010 Shanghai World Expo, omwe ndi likulu la Shanghai komanso malo otentha a anthu, omwe ali ndi ubwino wa malo ndi malo athunthu.
Pakati pawo, Hall 2 ndi holo yamitundu yapadziko lonse lapansi, pomwe Hall 1, 3 ndi 4 imakhala ndi makampani otsogola aku China. Pofuna kulimbikitsa bwino malingaliro opanga zovala zamaso ku China ndi zinthu zatsopano, wokonzayo adzakhazikitsa malo owonetsera apadera a "Designer Works" mkatikati mwa holo ya pansi, ndikukhazikitsa Hall 4 ngati "holo yogulitsira malonda". ". Kuphatikiza apo, chiwonetsero cha Shanghai International Eyewear Exhibition (Shanghai Eyewear Exhibition, International Eyewear Exhibition) ndichosavuta kwa ogula kuyitanitsa zinthu zomwe amazikonda nthawi yomweyo.
Mitundu yosiyanasiyana
Mitundu yonse ya magalasi: Mafelemu owonera, magalasi, magalasi, magalasi, magalasi a 3D, magalasi a digito, zida zamaso, magalasi ndi makina opanga magalasi, zida zamagalasi ndi zida, zida zamagalasi, nkhungu, zinthu zosamalira maso, ma lens ndi kuyeretsa ma lens. yankho, magalasi a magalasi, zida zachipatala za maso, mankhwala a maso, katundu wa fakitale wa magalasi, magalasi a maso, kuyesa ndi kuwongolera amblyopia, magazini okhudzana ndi sayansi ndi luso Zinthu ndi ziwonetsero, mabungwe amakampani a eyewear, ndi zina zotero.
Zida zapadera zamagalasi: zida zopangira magalasi, zida za optometry ndi zida, zida zopangira ndi zowonjezera zamagalasi, magalasi olumikizirana ndi zinthu zosamalira magalasi.
Chithandizo chapamwamba ndi ukadaulo womaliza: zida zopangira ndi zida, zida zokutira ndi zida zothandizira, chitetezo cha chilengedwe, zida zachitetezo ndi chitetezo, zida zokutira
Chiwonetserochi chili ndi owonetsa 758, kuphatikiza owonetsa 158 ochokera kumayiko 18 ndi zigawo padziko lonse lapansi. Pakati pawo, pali "nkhope zatsopano" za 20 ku International Museum, zomwe zimakhala pafupifupi 12%; Pali pafupifupi 80 owonetsa atsopano m'nyumba zapakhomo, zomwe zimawerengera 15% yazonse. Nkhope zatsopano ndi abwenzi akale, kusonkhana kosangalatsa!
Ndi malo owonetsera opitilira 70,000 masikweya mita, mitundu yopitilira 10 yazinthu zapamwamba komanso zopambana zaukadaulo monga magalasi adzuwa, magalasi owoneka bwino, magalasi amaso, zida ndi zida, zotumphukira ndi machitidwe apulogalamu amawonetsedwa bwino. Kuyika kokonzedwa bwino kwa mutu wa "Future Vision" ndi malo amakadi anthawi zonse zili pa Expo Exhibition Center, kukhala chowongolera nyengo kwa anthu.
Pachiwonetsero cha masiku atatu, mabungwe ndi mabizinesi omwe adatenga nawo gawo adachita pafupifupi zochitika 30 zamasikelo osiyanasiyana munthawi yomweyo, zomwe zikukhudza zomwe zachitika posachedwa pakupewa ndi kuwongolera kwa myopia, kupewa ndi kuwongolera mfundo za myopia, thanzi la dziko, chimango ndi ma lens. kumasulidwa kwatsopano ndi mitu ina yambiri, yolemera komanso yatsatanetsatane, kuthandiza alendo kusangalala ndi kumvetsetsa kokhazikika kwaukadaulo wamakono ndi chitukuko cha mafakitale cha optometry.
Makampani ambiri apakhomo ndi akunja adachita nawo chiwonetserochi.
Ma lens a resin ndi mtundu wa mandala opangidwa ndi zinthu zachilengedwe, mkati mwake ndi mawonekedwe a unyolo wa polima, wolumikizidwa komanso mawonekedwe atatu a netiweki, mawonekedwe a intermolecular amakhala omasuka, ndipo danga lapakati pa unyolo wa maselo limatha kupangitsa kusamuka. Kutumiza kwa kuwala ndi 84% -90%, kuyatsa kwabwino ndikwabwino, ndipo mandala a utomoni amatha kukana mwamphamvu.
Lens ya utomoni ndi mtundu wazinthu zachilengedwe, mkati mwake ndi mawonekedwe a unyolo wa polima, wolumikizidwa komanso mawonekedwe atatu a netiweki, mawonekedwe a intermolecular amakhala omasuka, ndipo danga lapakati pa unyolo wa maselo limatha kupangitsa kusamuka. Kutumiza kwa kuwala ndi 84% -90%, kuyatsa kwabwino ndikwabwino, ndipo mandala a utomoni amawonetsa kukana mwamphamvu.
Magalasi a resin ndi mtundu wa lens wowoneka bwino wopangidwa ndi utomoni. Pali mitundu yambiri yazinthu, ndipo poyerekeza ndi magalasi agalasi, ili ndi ubwino wake wapadera:
1. Kuwala. General utomoni magalasi ndi 0.83-1.5, ndi kuwala galasi 2.27 ~ 5.95.
2, kukana kwambiri. Kukaniza kwa magalasi a utomoni nthawi zambiri kumakhala 8 ~ 10kg/cm2, komwe kumakhala kangapo kuposa magalasi, kotero ndikosavuta kuthyoka, kotetezeka komanso kolimba.
3, kufala kwa kuwala kwabwino. M'dera lowoneka, ma transmittance a resin lens ndi ofanana ndi galasi. Chigawo cha infrared, chokwera pang'ono kuposa galasi; M'dera la ultraviolet, kufalikira kumachepa pamene kutalika kwa mafunde kumachepa, ndipo kuwala kokhala ndi utali wocheperapo 0.3um kumakhala pafupifupi kwathunthu.
4, mtengo wotsika. Magalasi opangira jakisoni, amangofunika kupanga nkhungu yeniyeni, imatha kupangidwa ndi anthu ambiri, kupulumutsa ndalama zolipirira ndi nthawi.
5, imatha kukwaniritsa zosowa zapadera. Mwachitsanzo, kupanga magalasi a aspherical sikovuta, ndipo magalasi agalasi ndi ovuta kuchita.
Kukangana
Apinda refractive index
Ndilo chiŵerengero cha sine cha ngodya yowunikira ya lens kupita ku kuwala kwa chochitika ndi Ngongole yowunikira. Mtengo wake nthawi zambiri umakhala pakati pa 1.49 ndi 1.74. Pamlingo womwewo, kuchuluka kwa refractive index, kuonda kwa mandala, koma kuchuluka kwa refractive index of the material, kumakhala koopsa kwambiri kubalalitsidwa kwake.
Kupindika kukana zokala
Amatanthauza mlingo wa kuwonongeka kwa kuwala transmittance wa mandala pamwamba pa zochita za kunja mphamvu. Kukandira kwa mandala ndi chinthu chofunikira chomwe chimakhudza moyo wautumiki komanso mawonekedwe a mandala. Mphamvu ya friction fog value (Hs) ku China ikuwonetsa kuti mtengo wake nthawi zambiri umakhala pakati pa 0.2-4.5, ndipo kutsika kumakhala bwinoko. Njira ya BAYER imagwiritsidwa ntchito kwambiri kumayiko akunja, ndipo mtengo wake umakhala pakati pa 0.8-4, ndipamwamba kwambiri. Nthawi zambiri amatchedwa magalasi owuma a utomoni, kukana kukanda kuli bwino kuposa magalasi a utomoni wamba.
Kupindika kwa UV cutoff rate
Imadziwikanso kuti mtengo wa UV, ndichizindikiro chofunikira chowunikira kutsekeka kogwira mtima kwa cheza cha ultraviolet cha magalasi. Mtengo wake uyenera kukhala wokulirapo kuposa 315nm, nthawi zambiri wopitilira 350nm komanso wochepera 400nm. Magalasi a UV400, omwe nthawi zambiri amamveka m'masitolo opangira kuwala, amatha kutsekereza cheza cha ultraviolet. Kuphatikiza apo, ndizothekanso kuwonjezera filimu yoteteza ma radiation ku lens ya resin.
Kupinda kwa kuwala
Chiŵerengero cha kuchuluka kwa kuwala komwe kukuwonetsedwa ndi lens ndi kuchuluka kwa chochitika cha kuwala. Kuchuluka kwa transmittance, lens imamveka bwino.
Nambala ya abbe yopindidwa
Amagwiritsidwa ntchito kufotokoza cholozera chosiyana cha kuthekera kwa kubalalitsidwa kwa zinthu zowonekera, ndipo angagwiritsidwe ntchito ngati kutanthauza kutsimikiza kwa mtundu wowuma wa kuwala kowoneka kwa mandala. Mtengo wake uli pakati pa 32 ndi 60, ndipo kumtunda kwa nambala ya Abbe ya mandala, kusokonezeka kochepa.
Kukaniza kukana kukhudzidwa
Zimatanthawuza mphamvu yamakina a mandala kuti apirire kukhudzidwa. Kukaniza kwa ma lens a utomoni ndikwamphamvu kuposa magalasi agalasi, ndipo ngakhale magalasi ena satha kusweka.
Palinso maubwino ambiri a ma lens a resin, apo ayi singakhale mandala omwe amagwiritsidwa ntchito kwambiri tsopano. Magalasi a utomoni amathanso kukutidwa, pulasitiki ndi yolimba, yabwino kwambiri kuposa magalasi ena, koma mtundu wa ma lens utomoni umakhala wosiyana kwambiri, kotero tikamafananiza magalasi, tiyenera kusankha mosamala, kuti tisankhe magalasi oyenera. kwa ife.
