2. Txoj kev Isobutylene
Xyoo 1982, Mitsubishi Rensi thiab Nyivpolymethyl methacrylate hmoovLub Tuam Txhab Monomer siv isobutylene / tert butyl cawv (TBA) ua raw khoom. Xyoo 1982, Mitsubishi Liyang thiab lwm lub tuam txhab tsim cov txheej txheem peb - isobutylene MMA thiab industrialized nws. Siv isobutylene ua raw khoom, thawj kauj ruam yog oxidize rau methacrolein, thiab theem ob yog oxidize rau methacrylic acid. Qhov thib peb kauj ruam yog esterification ntawm methacrylic acid thiab methanol los tsim MMA.
Xyoo 1998, Asahi Kasei Lub Tuam Txhab ntawm Nyij Pooj tau tsim ob qho -kauj ruam isobutylene MMA cog. Siv isobutylene ua raw khoom, thawj kauj ruam yog oxidize nws mus rau methacrolein, thiab cov kauj ruam thib ob yog esterify methacrolein nrog methanol thiab huab cua los ua polymethyl methacrylateThrough MAA cov kauj ruam, cov txheej txheem tshiab no zoo zam kev tawm tsam xws li MAA polymerization, ua kom yooj yim cov txheej txheem, txo cov nqi siv hluav taws xob, thiab txo cov nqi siv zog, thiab txo cov nqi siv nyiaj ntau. isobutylene raw khoom txoj kev sib tw ntau dua. Qhov kom zoo dua ntawm isobutene txoj kev yog tias nws ua rau tag nrho kev siv ntawm c4 feem nplua nuj nyob rau hauv raw cov ntaub ntawv: lub atom siv tus nqi siab (73%), uas yog 25% siab tshaj li cov ACH txoj kev, thiab 27% ntawm cov atoms uas tsis yog siv tsim dej molecules, uas zam cov tiam ntawm khib nyiab acid thiab cov khoom siv corrosion, tab sis qhov tsis zoo yog qhov yield yog tsawg.
Nws feem ntau yog siv los hloov iav. Cov khoom ntawm cov khoom yog raws li nram no:
khoom ntiag tug
1. Qhov ntom ntawm PMMA yog qis dua li iav: qhov ntom ntawm PMMA yog li 1.15-1.19g / cm3, ib nrab ntawm cov iav (2.40-2.80g / cm3), thiab 43% ntawm txhuas (lub teeb hlau).
2. Lub zog txhua yam ntawm polymethyl methacrylate yog siab: tus txheeb ze molecular hnyav ntawm PMMA yog hais txog 2 lab, uas yog ib tug ntev saw hlau polymer, thiab cov saw tsim cov molecule yog mos heev. Yog li, lub zog ntawm PMMA yog qhov siab, thiab nws qhov tensile thiab kev cuam tshuam tsis kam yog 7 mus rau 18 npaug siab dua li cov iav zoo tib yam. Muaj ib hom plexiglass uas tau ua kom sov thiab ncab. Cov saw hlau molecular nyob rau hauv nws yog teem nyob rau hauv ib txoj kev zoo heev, thiaj li hais tias lub toughness ntawm cov khoom yog ho txhim kho. Cov ntsia hlau yog siv los tsav mus rau hauv plexiglass. Txawm tias cov ntsia hlau nkag mus, tsis muaj qhov tawg yuav tshwm sim. Cov plexiglass zoo li no yuav tsis tawg mus rau hauv tej daim tom qab raug punctured los ntawm mos txwv. Yog li ntawd, lub stretched PMMA yuav siv tau raws li mos mos iav thiab kuj raws li lub cockpit cover ntawm tub rog aircraft.
3. Lub melting point ntawm polymethyl methacrylate yog tsawg, tsawg tshaj li lub siab kub ntawm iav, uas yog hais txog 1000 degree.
4. High light transmittance ntawm PMMA
(1) Lub teeb pom kev zoo: PMMA yog cov khoom siv pob tshab zoo tshaj plaws tam sim no, nrog lub teeb xa hluav taws xob ntawm 92%, uas siab dua li iav.
(2) Ultraviolet lub teeb: quartz tuaj yeem nkag mus rau ultraviolet lub teeb, tab sis tus nqi siab. Cov iav zoo tib yam tuaj yeem nkag mus rau 0.6% ultraviolet lub teeb. PMMA tuaj yeem lim cov teeb ci ultraviolet nrog wavelength tsawg dua 300nm, tab sis cov nyhuv lim dej tsis zoo ntawm 300nm thiab 400nm. Qee cov tuam txhab lag luam tau coated PMMA nto los ua kom cov nyhuv thiab cov cuab yeej lim dej 300nm txog 400nm ultraviolet lub teeb. Ntawm qhov tod tes, piv nrog polycarbonate, polymethyl methacrylate muaj kev ruaj ntseg zoo dua thaum raug ultraviolet lub teeb.
(3) Infrared ray: PMMA tso cai rau infrared ray (IR) nrog wavelength tsawg dua 2800nm kom dhau mus. IR nrog ntev wavelength tuaj yeem raug thaiv thaum nws tsawg dua 25000 nm. Muaj cov xim tshwj xeeb PMMA, uas tuaj yeem cia IR ntawm cov wavelength tshwj xeeb dhau los thiab thaiv lub teeb pom kev (tso rau cov chaw taws teeb tswj lossis thermal sensing, thiab lwm yam).
(4) Lub iav hloov pauv kub ntawm polymethyl methacrylate yog li 105℃C.
chemical khoom
Vim nws cov ceg loj loj thiab cov viscosity siab ntawm polymethyl methacrylate, kev ua haujlwm ceev kuj qeeb thaum siv txoj kev ua thermal. Lub plexiglass tuaj yeem tsis tsuas yog txiav nrog lub tshuab dhos thiab laum nrog lub tshuab drilling, tab sis kuj tseem raug khi rau hauv ntau yam duab nrog acetone, chloroform, thiab lwm yam. Nws kuj tuaj yeem ua tiav rau hauv ntau yam khoom, xws li lub dav hlau cabin npog rau cov hniav thiab cov hniav, los ntawm cov yas molding xws li tshuab molding, txhaj, extrusion, thiab lwm yam.
Cyanoacrylate, dichloromethane los yog chloroform tuaj yeem yaj me ntsis cov iav organic, thiab tom qab ntawd ob daim iav organic tuaj yeem sib koom ua ke.
Kev tsim khoom ntawm 1 kg ntawmpolymethyl methacrylate hmoovyuav tsum tau txog 2 kg ntawm cov roj. Nyob rau hauv lub xub ntiag ntawm cov pa, PMMA pib hlawv ntawm 458℃C. Tom qab kub hnyiab, nws generates carbon dioxide, dej, carbon monoxide thiab ib co tsis tshua muaj molecular compounds, xws li formaldehyde.
