MMA (Methyl Methacrylate): Monomer ea Bohlokoa bakeng sa Li-polymer tse nang le Ts'ebetso e Phahameng
Masimo a Maholo a Kopo
Indastering ea polasetiki, PMMA e sebelisoa haholo bakeng sa ho etsa maqephe a bonaletsang, lipeipi le lisebelisoa tsa mahlo ka lebaka la thepa ea eona e phahameng ea mahlo. E fana ka ponahalo e phahameng, index e tlase ea refractive, le khanyetso e ntle ea UV, e leng se etsang hore e lokele lits'ebetso tse kang matšoao, li-display stand, mabone a morao a likoloi le li-canopies tsa lifofane. Ho feta moo, khanyetso e ntle ea lik'hemik'hale ea PMMA le matla a mechini li etsa hore e be ntle bakeng sa lisebelisoa tsa ho lokisa lijo le lisebelisoa tsa bongaka.
Lefapheng la ho maneha le ho khomaretsa, MMA e sebediswa ho kopanya di-resin tse fapaneng tse sebetsang hantle. Di-resin tsena di bontsha ho kgomarela ho hoholo, ho hanyetsa boemo ba lehodimo, le ho hanyetsa dikhemikhale, e leng se etsang hore di sebediswe haholo ho maneha ka meralo, ho maneha ka dikoloi, le ho kenya disebediswa tsa elektroniki. Di-glue tse thehilweng ho MMA, tse tsejwang ka bokgoni ba tsona ba ho kgomarela ka potlako le ho matlafatsa matla a tsona a ho kopanya, di sebediswa haholo bakeng sa lehong la ho kopanya, tshepe le thepa ya polasetiki.
Lefapheng la thepa ea optical, MMA ke thepa ea bohlokoa bakeng sa ho etsa likhoele tsa optical le lilense. Litšobotsi tsa eona tse phahameng tsa optical le ho hanyetsa boemo ba leholimo li etsa hore e be thepa e loketseng bakeng sa lits'ebetso tsa optical, ho kenyeletsoa lisebelisoa tsa puisano tsa fiber optic le lilense tsa optical tse sebetsang hantle. Ho feta moo, MMA e sebelisoa tlhahisong ea litataiso tsa leseli le li-sensor tsa optical.
Indastering ea metsoako, MMA e sebelisoa ho hlahisa metsoako e thehiloeng ho methyl methacrylate resin. Metswako ena e fana ka matla a phahameng, ho ba le bongata bo tlase, le ho hanyetsa ho bola ho hoholo, e leng se etsang hore e sebelisoe haholo lits'ebetsong tsa lifofane, likoloi le lisebelisoa tsa lipapali. Mohlala, metsoako e thehiloeng ho MMA e sebelisoa mapheong a lifofane, 'meleng oa likoloi le lihlopheng tsa kolofo.
