Lub lens resin yog cov khoom siv organic.Sab hauv yog cov qauv saw hlau polymer, uas txuas nrog rau kev tsim cov qauv peb sab.Cov qauv sib xyaw ua ke yog qhov yooj yim, thiab muaj qhov chaw nruab nrab ntawm cov saw hlau molecular uas tuaj yeem tsim kom muaj kev sib txawv txav.Lub teeb xa hluav taws xob yog 84.% -90%, lub teeb kis tau zoo, thiab cov khoom siv kho qhov muag muaj qhov cuam tshuam zoo.
Cov resin yog hydrocarbon (hydrocarbon) tso tawm los ntawm ntau yam nroj tsuag, tshwj xeeb tshaj yog conifers.Nws muaj nuj nqis rau nws cov qauv tshuaj tshwj xeeb thiab nws siv los ua cov xim latex thiab nplaum.Txij li thaum nws yog ib tug sib tov ntawm ntau yam polymer tebchaw, lub melting point kuj txawv.
Cov resin tuaj yeem muab faib ua ob hom: ntuj cob thiab hluavtaws cob.Muaj ntau ntau hom resins, uas yog dav siv nyob rau hauv lub teeb thiab hnyav kev lag luam, thiab feem ntau pom nyob rau hauv lub neej txhua hnub, xws li yas, resin iav thiab xim.Resin lo ntsiab muag yog lo ntsiab muag uas muaj tshuaj lom neeg los ntawm resin thiab ua tiav thiab polished.
