Acrylic yog polymethyl methacrylate, abbreviated li PMMA, yog ib hom polymer polymer ua los ntawm methyl methacrylate polymerization, tseem hu ua organic iav, nrog siab transparency, siab huab cua tsis kam, siab hardness, yooj yim ua molding thiab lwm yam zoo, feem ntau yog siv raws li ib tug hloov khoom siv rau iav.
Tus txheeb ze molecular pawg ntawm PMMA yog kwv yees li 2 lab, thiab cov saw hlau tsim cov molecules kuj yog mos, yog li lub zog ntawm PMMA kuj yog siab, thiab tensile thiab cuam tshuam tsis kam ntawm PMMA yog 7 ~ 18 npaug siab dua li cov iav zoo tib yam.Thaum nws siv los ua plexiglass, txawm tias nws tawg, nws yuav tsis tawg zoo li iav zoo tib yam.
PMMA yog tam sim no qhov zoo tshaj plaws optical kev ua tau zoo ntawm pob tshab polymer cov ntaub ntawv, transmittance ntawm 92%, siab dua iav thiab PC transmittance, uas tau dhau los ua tus yam ntxwv tseem ceeb tshaj plaws ntawm ntau daim ntawv thov.
Cov huab cua tsis kam ntawm PMMA kuj yog qhov thib ob rau tsis muaj nyob rau hauv cov yas sib xws, uas yog siab dua li PC, PA thiab lwm yam yas.Tsis tas li ntawd, cov cwj mem hardness ntawm PMMA tuaj yeem ncav cuag 2H, uas yog siab dua li lwm cov yas zoo li PC, thiab muaj qhov zoo ntawm khawb tsis kam.
Vim nws cov yam ntxwv zoo heev, PMMA tau siv dav hauv tsheb, hluav taws xob thiab khoom siv hauv tsev, cov khoom siv, teeb pom kev zoo, kev tsim kho thiab cov khoom siv hauv tsev, kev kho mob thiab lwm yam.
Kev siv PMMA hauv Automotive Field
Feem ntau, PMMA nyob rau hauv lub tsheb taillight, dashboard daim npog qhov ncauj, sab hauv kem thiab cov khoom siv kho kom zoo nkauj, sab hauv lub teeb, rearview daim iav plhaub thiab lwm yam teb yog siv, feem ntau yog siv nyob rau hauv kev xav tau rau pob tshab, translucent thiab siab gloss thiab lwm yam teb.
1, PMMA siv nyob rau hauv tsheb taillights
Lub teeb tsheb tau muab faib ua lub teeb taub hau thiab lub teeb taillights, thiab cov ntaub ntawv pob tshab yog siv rau qhov chaw xws li teeb pom kev zoo.Lub teeb taub hau thiab pos huab ntxoov ntxoo siv polycarbonate PC cov ntaub ntawv, qhov no yog vim hais tias nyob rau hauv tus txheej txheem ntawm kev tsav tsheb lub taub hau siv lub sij hawm yog feem ntau kuj ntev, thaum lub tsheb tsav tsheb ntawm lub lampshade cuam tshuam cov kev xav tau ntau dua.Tab sis PC siv rau lub teeb taub hau kuj muaj cov thev naus laus zis nyuaj, tus nqi siab, kev laus yooj yim thiab lwm yam tsis zoo.
Taillights feem ntau tig teeb liab, nres teeb, lub teeb siv tsawg, lub sijhawm ua haujlwm luv, yog li cov kev xav tau ntawm cov cua sov kuj tseem tsawg, feem ntau yog siv cov ntaub ntawv PMMA, PMMA transmittance 92%, siab dua 90% PC, refractive index 1.492, huab cua tsis zoo. , high deg hardness, yog taillight daim npog qhov ncauj, reflector, lub teeb qhia ntawm cov khoom zoo tagnrho.Vim nws cov tawv tawv siab, PMMA muaj kev khawb zoo thiab tuaj yeem siv ncaj qha yam tsis muaj kev tiv thaiv saum npoo thaum siv los ua cov khoom siv sab nraud ntawm daim iav.Lub teeb tawg PMMA muaj cov yam ntxwv siab tawg thiab yooj yim kom ua tiav cov teeb pom kev zoo, uas yog ib qho ntawm cov ntaub ntawv tseem ceeb hauv daim ntawv thov tam sim no.
2, PMMA rau dashboard daim npog qhov ncauj
Lub npog ntsej muag dashboard feem ntau ua lub luag haujlwm ntawm kev tiv thaiv cov cuab yeej thiab nthuav tawm cov ntaub ntawv ntsuas kom raug.Lub ntsej muag lub ntsej muag yog feem ntau txhaj tshuaj molded, PMMA yog siv ntau dua, nrog lub siab pob tshab, muaj zog txaus, nruj, ruaj khov zoo, nyob rau hauv lub hnub ci hluav taws xob thiab lub cav khib nyiab kub hauv qhov kub tsis deformation, nyob rau hauv lub sij hawm ntev kub tsis deformation. , tsis poob, tsis cuam tshuam qhov tseeb ntawm qhov ntsuas.
3, Sab nrauv kab thiab trim daim
Lub tsheb kem tau muab faib ua ABC kem, nws qhov kev ua tau zoo yog qhov siab gloss (feem ntau yog piano dub), huab cua tsis kam, siab kub tsis kam, khawb tsis kam, feem ntau siv cov txheej txheem yog ABS + tshuaj tsuag xim, PP + tshuaj tsuag xim thiab PMMA + ABS ob chav extrusion. scheme, thiab toughened PMMA scheme.Piv nrog rau cov txheej txheem pleev xim, PMMA tuaj yeem tshem tawm cov txheej txheem txau, ntau tus phooj ywg ib puag ncig, tus nqi qis, thiab maj mam dhau los ua cov tswv yim tseem ceeb.
4, PMMA yog siv rau lub teeb sab hauv
Lub teeb sab hauv suav nrog cov teeb nyeem ntawv thiab teeb pom kev zoo.Lub teeb nyeem ntawv yog ib feem ntawm lub tsheb lub teeb pom kev sab hauv, feem ntau yog ntsia rau pem hauv ntej lossis lub ru tsev.Txhawm rau tiv thaiv lub teeb pom kev zoo, cov teeb nyeem ntawv feem ntau tawg lub teeb, siv matte lossis frosted PMMA lossis PC daws teeb meem.
Atmosphere teeb yog ib hom teeb pom kev zoo uas tuaj yeem tsim kom muaj cua sov thiab txhim khu kev nkag siab ntawm lub tsheb.Lub teeb qhia strips siv nyob rau hauv lub teeb ambient yog muab faib ua ob hom: mos thiab tawv raws li lawv cov kev ntxhib los mos.Lub teeb qhia kev ntxhib los mos yog tawv, tsis tuaj yeem khoov, feem ntau los ntawm kev txhaj tshuaj molding lossis extrusion molding, cov khoom siv rau PMMA, PC thiab lwm yam ntaub ntawv nrog pob tshab.
5, PMMA yog siv nyob rau hauv lub rear saib daim iav vaj tse
Daim iav saib sab nraub qaum feem ntau xav tau siab gloss thiab dub ci ntsa iab, thaum xav tau lub zog muaj zog, khawb tsis kam thiab huab cua tsis kam.Raws li cov duab ntawm daim iav plhaub feem ntau yog nkhaus, nws yog ib qho yooj yim los tsim kev ntxhov siab, yog li cov machining kev ua tau zoo thiab toughness yuav tsum tau siab heev.Cov txheej txheem ib txwm muaj ABS tshuaj pleev xim, tab sis cov txheej txheem kev ua qias tuaj yog qhov hnyav, cov txheej txheem muaj ntau, kev siv cov txheej txheem PMMA tuaj yeem ua tiav cov tshuaj tsuag dawb, feem ntau ntawm no siv cov khoom siv tawv tawv PMMA, kom tau raws li cov qauv ntsuas hauv qhov kev sim poob thiab lwm yam. tej yaam num.
Cov saum toj no yog cov niaj hnub daim ntawv thov ntawm PMMA nyob rau hauv lub automotive teb, feem ntau muaj feem xyuam rau optics los yog zoo li, PMMA ntxiv possibilities rau lub automotive teb.
