Ethyl methacrylate muaj qee yam tshuaj tshwj xeeb, xws li tshuaj tiv thaiv zoo li ob daim ntawv cog lus polymerization, ntxiv, thiab transesterification ntawm cov organic esters. Nws molar refractivity yog 31.18, molar ntim (cm³ / mol) yog 125.9, nto nro (dyne / cm) yog 24.6, thiab polarizability yog 12.36.
Ethyl methacrylate muaj ntau hom kev lag luam, feem ntau yog siv rau kev npaj cov polymers thiab copolymer, hluavtaws resins, organic iav, thiab coatings. Tshwj xeeb, nws tuaj yeem siv los tsim cov khoom siv hluavtaws, xws li PMMA (polymethyl methacrylate), PA (polyamide), PET (polyethylene terephthalate), thiab lwm yam. Cov resins no tau siv dav hauv kev lag luam xws li tsheb, hluav taws xob, thiab kev tsim kho. Tsis tas li ntawd, nws tseem tuaj yeem siv los tsim cov nplaum tshwj xeeb, xws li UV-kho cov nplaum, cov nplaum kub yaj, cov nplaum nplaum tsheb, thiab lwm yam. Cov khoom siv no yog siv rau hauv kev tsim kho, hluav taws xob, tsheb, thiab textiles. Lub caij no, ethyl methacrylate tseem tuaj yeem siv los ua cov txheej txheem tiv thaiv ultraviolet los txhim kho huab cua tsis kam thiab ua haujlwm ntev ntawm cov khoom.
Cov ntaub ntawv Photochromic xa mus rau ib hom khoom siv uas tuaj yeem hloov xim thaum zoo siab los ntawm lub teeb ci. Qhov tshwm sim no cuam tshuam txog kev hloov pauv ntawm cov qauv molecular ntawm qee cov tebchaw nyob rau hauv qhov kev txiav txim ntawm lub teeb nrog cov wavelengths tshwj xeeb thiab kev siv zog, uas ua rau muaj kev hloov pauv ntawm lub teeb pom kev ncov, uas yog, kev hloov xim, thiab qhov kev hloov no feem ntau thim rov qab. Cov nyhuv photochromic tsis txwv rau cov ntaub ntawv inorganic; kuj tseem muaj cov ntaub ntawv organic xws li spiropyran derivatives, azobenzene derivatives, thiab lwm yam. Cov ntaub ntawv organic photochromic yuav hloov xim thaum irradiated los ntawm lub teeb nrog wavelengths tsim nyog thiab siv tau rau cov ntaub ntawv kaw.
Cov ntaub ntawv Photochromic muaj ntau yam kev siv, suav nrog kev tsim tus kheej yees duab, radiation dosimeters, computer photochemical keyboards, thiab kho qhov muag cov ntaub ntawv xov xwm. Thawj daim ntawv thov kev lag luam ua tiav tau pib hauv xyoo 1960. Ob tus kws tshawb fawb cov ntaub ntawv, Amistead thiab Stooky los ntawm Corning Studios hauv Tebchaws Meskas, thawj zaug pom cov khoom siv rov qab photochromic ntawm silver halide (AgX) iav.
Tsis tas li ntawd, cov ntaub ntawv photochromic kuj muaj cov ntawv thov tseem ceeb hauv thaj chaw optoelectronic, xws li photochromic iav thiab photochromic fibers. Photochromic iav tuaj yeem ua rau tsaus ntuj hauv lub teeb irradiation los ntawm kev ntxiv cov ntsiab lus tsis tshua muaj hauv ntiaj teb thiab manganese ions rau hauv silicate iav thiab rov ua nws cov xim qub thaum tsis muaj irradiated. Photochromic fibers yog cov fibers npaj los ntawm kev sib xyaw cov ntaub ntawv photochromic nrog cov polymers siab los ntawm kev sib tov spinning, blend spinning, los yog composite spinning cov tswv yim.
