1. Chii chinonzi PC lenzi?
PC kuita kwakanaka kwe thermoplastic engineering mapurasitiki, mapurasitiki mashanu einjiniya mukati mekujeka kwechigadzirwa, asiwo mumakore achangopfuura kukura nekukurumidza kwemapurasitiki einjiniya.Parizvino, inoshandiswa zvakanyanya mu optics, zvemagetsi, zvivakwa, mota, hutano hwehutano uye mamwe minda, kunyanya pakugadzira magirazi emaziso.

2. Sei achinzi malenzi emuchadenga?
POLYCARBONATE(PC) chinhu chakagadzirwa nemasainzi kugadzira midziyo yekutsvagisa muchadenga inokodzera nharaunda yakasarudzika yechadenga, saka inowanzozivikanwa senzvimbo lens.

3. Chii chakanaka pamusoro pazvo?
PC zvinhu zvine mabhenefiti e-ultra-thin, ultra-light, high collision resistance, UV dziviriro uye yakanaka transmittance mwenje, inoshandiswa zvakanyanya muinjiniya mapurasitiki akajeka zvinhu, Iine kugadzikana kwakanaka uye haina magetsi ekufambisa, saka chiyero chekushandisa chakapamhama. , uye yakagadzirwa nePC material lens nature ine mabhenefiti ari pamusoro, kunyanya akakodzera nhamba yepamusoro, teerera kune vakanaka, vanhu vemitambo, vana, vanhu vakuru vanopfeka, seUnited States yakaraira magirazi rudzi rwevana vari pasi pemakore gumi nematatu inofanirwa kupfeka ma lens ePC.
General resin lenzi zvinhu zvinopisa zvakasimba, kureva kuti, iyo mbishi ndeyemvura, inopisa kuita lenzi dzakasimba.PC chidimbu ndeye thermoplastic material, kureva kuti, iyo mbishi yakasimba, mushure mekupisa, kuumbwa kwelens, saka iyi lens chigadzirwa chichave chakanyanyisa deformation, chisingakodzeri hunyoro hwepamusoro uye nguva dzekupisa.PC lens ine kusimba kwakasimba, isina kutyoka (2cm inogona kushandiswa kune bulletproof girazi), saka inonziwo kuchengetedza lens.Iyo chaiyo giravhiti ingori magiramu maviri pacubic centimita, zvichiita kuti ive chinhu chakareruka pari zvino chinoshandiswa kumalenzi.PC lens mugadziri ndiye anotungamira pasirese Esilu, mabhenefiti ayo anoratidzwa mune lens aspheric kurapwa uye kuomesa kurapa.
PC nzvimbo lenzi dzakagadzirwa ne polycarbonate lenses, uye akajairwa resin (CR-39) lenses ane yakakosha misiyano!PC inowanzonzi bulletproof girazi, saka ma lenzi ePC anoomerera kune akanakisa hunhu hwezvigadzirwa zvemhando yepamusoro kuramba, uye nekuda kweiyo yakakwira refractive index uye huremu huremu, kuderedza huremu hwelens zvakanyanya, kune zvimwe zvakanaka zvakaita se: 100% Kudzivirirwa kweUV, makore 3-5 haaite yero.Kana pasina dambudziko mukuita, huremu hureruke 37% pane yakajairwa pepa resin, uye kupikisa kwemaitiro kunosvika kagumi nemaviri resin yakajairwa!

4. Nhoroondo yePC lenses
Muna 1957,
Kambani yeAmerican GE(General Electric) yakatungamira mukugadzirwa kwePc(polycarbonate) plastiki, ndokudaidza Lexan.Kambani yeGerman Bayer yakatevera nePC yavo yepurasitiki Makrolen.
Muma1960
Zana remakore rechipiri rakapera.PPG yakashandura iyo CR-39 resin zvinhu kubva kumauto kuti igadzire lenzi dzekushandiswa kwevanhu.
Muma1970
Mukutanga kwema1970, varwere vakatanga kugamuchira CR-39 lens.
Muna 1973,
85% girazi lenzi uye 15% CR-39 lenzi.
Muna 1978,
Iine mukana wemauto uye aerospace mapurojekiti, Gentex yakatanga kushandisa PC kugadzira lenzi dzekuchengetedza.
Muna 1979,
Munyika dzakabudirira, iyo lens zvinhu inoshandurwa kubva pagirazi kuenda kuCR-39 resin.Kugumisa iyo inoda kusvika 600-gore kutonga kwegirazi lens.
Muna 1985,
Vision-ease Lenses Inc. ndiyo yakatanga kuunzwa kwemalenzi ePC.
Muna 1991,
Transitions, Inc. inoburitsa chizvarwa chekutanga chemavara anochinja resin lenzi.
Muna 1994,
PC lenses account yegumi muzana yemusika weUS.
Muna 1995,
Iyo polarizing PC lens yakazvarwa.
Muna 2002,
PC lenzi dzinoita makumi matatu neshanu muzana emusika weUS, nepo magirazi lenzi ari pasi pe35%.
