Qhov sib txawv tseem ceeb ntawm polycarbonate thiab Plexiglass yog cov polycarbonate muaj cov carbonate txuas ntxiv ua cov chav nyob, hos Plexiglass muaj cov methyl methacrylate units ua cov units rov ua dua.
Polycarbonate thiab Plexiglass yog cov polymers. Polycarbonate yog cov khoom siv hluavtaws uas cov monomer units txuas nrog ib leeg los ntawm kev sib txuas carbonate thaum Plexiglass yog lub npe lag luam rau polymethyl methacrylate. Lawv muaj cov qauv tshuaj sib txawv, yog li cov khoom sib txawv ntawm lub cev thiab kev siv.
YPolycarbonate yog dab tsi?
Polycarbonate yog cov khoom siv hluavtaws uas nws cov monomer txuas mus rau ib leeg los ntawm kev sib txuas carbonate. Cov khoom no yog ib hom yas uas tsim los ntawm cov tshuaj tiv thaiv ntawm Bisphenol A thiab phosgene, uas yog ob yog monomers uas tsis muaj cov carbonate pawg. Txawm li cas los xij, tom qab polymerization, cov saw hlau polymer yog tsim los ntawm kev sib txuas ntawm carbonate, uas ua rau lub npe cov polymers li polycarbonates.
Polycarbonate polymers muaj cov nplhaib uas muaj ntxhiab. Cov khoom no muaj nyob rau hauv ntau yam xim. Feem ntau, cov polymers no muaj cov pob tshab, tab sis peb tuaj yeem ua qee cov khoom xim uas feem ntau yog translucent, nyob ntawm qhov siv ntawm cov xim.
Daim duab 01: Rov Ua Chav Ua Haujlwm ntawm Polycarbonate
Thaum xav txog cov txheej txheem polymerization ntawm polycarbonate, nws yog txheej txheem kev loj hlob ntawm cov txheej txheem polymerization. Hauv cov txheej txheem no, cov tshuaj tiv thaiv condensation uas koom nrog ob pawg ua haujlwm tshwm sim (ib qho monomer unsaturated tsis koom nrog). Polycarbonate yog cov khoom muaj zog thiab pob tshab. Tsis tas li ntawd, qhov toughness thiab optical clarity ntawm cov khoom no ua rau nws tsim nyog rau kev siv sab hauv tsev thiab sab nraum zoov. Polycarbonate tau yooj yim machined, thiab cov khoom no kuj muaj qhov zoo ntawm qhov ruaj khov nrog lub zog muaj zog.
Plexiglass yog dab tsi?
Plexiglass yog lub npe lag luam rau polymethyl methacrylate. Nws yog cov khoom siv polymer. Lub npe IUPAC ntawm cov polymer no yog Poly (methyl 2-methyl propanoate), thiab cov tshuaj formula ntawm lub rov ua dua ntawm cov polymer yog (C5O2H8) n. Txawm li cas los xij, molar mass txawv. Qhov ceev yog 1.18 g / cm3, thiab melting point yog 160 ° C. Muaj peb txoj hauv kev loj ntawm kev sib txuas cov polymer no: emulsion polymerization, kua polymerization thiab bulk polymerization.
Daim duab 02: Rov ua dua Chav ntawm Plexiglass
Lucite yog lub npe lag luam ntawm polymethyl methacrylate. Lwm cov npe lag luam zoo yog Crylux, Plexiglass, Acrylite, thiab Perspex. Nws yog pob tshab thermoplastic polymer. Nws yog ib qho tseem ceeb ua lwm txoj rau iav hauv nws daim ntawv. Ntxiv mus, nws muaj txiaj ntsig zoo li cov cam khwb cia rau hauv cov inks thiab coatings.
Ntxiv rau cov no, cov polymer no muaj zog, tawv thiab muaj lub teeb yuag. Qhov ntom ntawm cov polymer no tsawg dua li ib nrab ntawm qhov ntom ntawm iav. Txawm li cas los xij, nws muaj kev cuam tshuam ntau dua li iav thiab polystyrene. Tsis tas li ntawd, cov polymer no tuaj yeem xa mus ib puag ncig 92% ntawm lub teeb pom kev, yog li nws tuaj yeem lim UV lub teeb uas muaj lub wavelength hauv qab 300 nm.
Qhov txawv ntawm Polycarbonate thiab Plexiglass yog dab tsi?
Polycarbonate thiab Plexiglass yog cov khoom siv polymer. Qhov sib txawv tseem ceeb ntawm polycarbonate thiab Plexiglass yog tias polycarbonate muaj cov carbonate txuas ntxiv ua chav tsev rov qab thaum Plexiglass muaj cov methyl methacrylate units raws li qhov rov ua dua chav tsev.
Ntxiv mus, polycarbonate muaj cov nplhaib uas muaj ntxhiab thaum Plexiglass tsis muaj cov nplhaib uas muaj ntxhiab. Yog li, qhov no yog lwm qhov sib txawv ntawm polycarbonate thiab Plexiglass.
Hauv qab infographic qhia txog qhov sib txawv ntawm polycarbonate thiab Plexiglass.
Summary – Polycarbonate vs Plexiglass
Polycarbonate thiab Plexiglass yog cov khoom siv polymer uas muaj cov qauv tshuaj sib txawv; yog li, muaj cov khoom sib txawv thiab kev siv. Qhov sib txawv tseem ceeb ntawm polycarbonate thiab Plexiglass yog tias polycarbonate muaj cov carbonate txuas ntxiv ua chav tsev rov qab thaum Plexiglass muaj cov methyl methacrylate units raws li qhov rov ua dua chav tsev.
