A. Tsawg ntom ntom: vim qhov sib txawv ntawm cov saw hlau molecular, tus naj npawb ntawm cov molecules ntawm ib chav tsev ntim me me, uas txiav txim siab qhov zoo ntawm lub lens resin: tsis tshua muaj lub ntiajteb txawj nqus thiab lub teeb kev ntxhib los mos, uas yog 1/3-1/2 ntawm iav lens;
B. Qhov nruab nrab refractive index: zoo tib yam CR-39 propylene diethylene glycol carbonate, refractive index yog 1.497-1.504.Tam sim no, lub siab tshaj plaws refractive index ntawm resin lo ntsiab muag muag nyob rau hauv Shenyang tsom iav khw muag khoom yog aspherical ultra-thin hardened zaj duab xis resin lens, refraction tus nqi yuav ncav cuag 1.67, thiab tam sim no muaj resin lo ntsiab muag nrog ib tug refractive index ntawm 1.74.
C. Qhov saum npoo hardness yog qis dua li iav, thiab nws yooj yim rau khawb los ntawm cov khoom tawv.Yog li ntawd, nws yuav tsum tau hardened.Cov khoom siv tawv tawv yog silica, tab sis lub hardness tsis zoo li lub hardness ntawm iav.Yog li ntawd, tus neeg hnav yuav tsum xyuam xim rau lub lens.kev saib xyuas;
D. Lub elasticity yog zoo.Vim qhov chaw nruab nrab ntawm cov organic molecular chains, qhov elasticity yog 23-28 npaug ntawm cov iav.Lwm tus yam ntxwv tseem ceeb ntawm cov ntawv resin yog txiav txim siab - kev cuam tshuam zoo.Cov teb chaws Europe, Asmeskas, thiab Nyij Pooj txwv tsis pub menyuam yaus hnub nyoog qis dua 16 xyoo los hnav cov iav lo ntsiab muag;
E. Kev pab txhawb nqa: Nws tuaj yeem muab ntxiv kom tau txais cov haujlwm xws li tiv thaiv cov kab hluav taws xob tsis zoo thiab tsis muaj xim.
