I-MMA (Methyl Methacrylate): I-Monomer eqakathekileko yama-Polymer asebenza kuhle khulu
Iindawo ezikulu zokusebenza
Ebubulweni lamaplastiki, i-PMMA isetjenziselwa khulu ukwenza amashidi akhanyako, amashubhu, kanye neensetjenziswa zokubona ngebanga lezakhiwo zayo ezihle zokubona. Inikeza ukukhanya okuphezulu, inkomba ephasi yokuphuka, nokujamelana okuhle khulu kwe-UV, okwenza bona ilungele ukusetjenziswa okufana namatshwayo, iindawo zokutjengisa, amalambu wangemuva weenkoloyi, kanye nama-canopy weemphaphamtjhini. Phezu kwalokho, ukujamelana kwamakhemikhali kwe-PMMA kanye namandla womtjhini kwenza bona ibe yinto ehle khulu emitjhini yokupheka ukudla kanye namadivayisi wezokwelapha.
Emkhakheni wokugcoba nokunamathela, i-MMA isetjenziselwa ukwenza ama-resin ahlukahlukeneko asebenza kuhle khulu. Ama-resin la atjengisa ukunamathelana okuhle khulu, ukujamelana nobujamo bezulu, nokujamelana namakhemikhali, okwenza bona asetjenziswe khulu ekugcotshweni kwezakhiwo, ekugcotjhweni kweenkoloyi, kanye nokufaka iinsetjenziswa ze-elekthronikhi. Iinamatheli ezisekelwe ku-MMA, ezaziwa ngokuphola kwazo msinyana kanye namandla wokubopha aqinileko, zisetjenziselwa khulu ukubopha iinkuni, iinsimbi, kanye nezinto zeplastiki.
Emkhakheni wezinto zokubona, i-MMA yinto eqakathekileko yokwenza imicu yokukhanya namalensi. Iimpawu zayo ezihle zokukhanya nokujamelana nobujamo bezulu kwenza bona ibe yinto ehle khulu yokusetjenziswa kokukhanya, okufakahlangana amadivayisi wokuthintana we-fiber optic kanye namalensi wokukhanya asebenza kuhle khulu. Phezu kwalokho, i-MMA isetjenziselwa ukukhiqiza imihlahlandlela yokukhanya kanye neenzwa zokukhanya.
Ebubulweni lezinto ezihlanganisiweko, i-MMA isetjenziselwa ukukhiqiza izinto ezihlanganisiweko ezisekelwe ku-methyl methacrylate resin. Iinhlanganisela lezi zinikela ngamandla aphezulu, ukuminyana okuphasi, nokujamelana nokugqwala okuhle khulu, okwenza bona zisetjenziswe khulu eensetjenzisweni zeenqhema zeenqhema zeenqhema, iinkoloyi, kanye nezemidlalo. Ukwenza isibonelo, iinhlanganisela ezisekelwe ku-MMA zisetjenziswa emaphikweni weemphaphamtjhini, emizimbeni yeenkoloyi, kanye namaklabhu wegalofu.

Ngokufingqa
Ngokuragela phambili kwethekhnoloji, iindawo zokusebenzisa i-MMA zihlala zikhula. Ukwenza isibonelo, embonini yokuphrinta ye-3D, i-MMA isetjenziselwa ukukhiqiza izinto zokuphrinta ze-3D ezisebenza kuhle khulu. Emkhakheni wezokwelapha, i-MMA isetjenziselwa ukwenza izinto zokwelapha ezibolako kanye nama-scaffold wobunjiniyela bezicubu. Ukusebenza ngezinto ezinengi nokusebenza kuhle kwe-MMA kwenza bona ibe yinto eqakathekileko embonini yesimanjemanje, inikela ngokusekela okunamandla ekuthuthukisweni kwemikhakha eminengi.
