Acrylic yog polymethyl metharichlate, lus luv li pmma, yog qhov muaj zog ntawm cov organic, tseem muaj cov khoom siv organic, tseem muaj kev sib xyaw ua ke, feem ntau yog siv ua a hloov cov khoom siv rau iav.
Tus txheeb ze cov molecular loj ntawm PMMA yog li 2 lab, thiab lub zog ntawm PMMA yog 7 ~ 18 npaug siab tshaj li ntawm lub khob dog dig. Thaum nws tau siv ua Pleexiglass, txawm tias nws tau tawg, nws yuav tsis tawg zoo li iav zoo tib yam.
PMMA yog tam sim no yog qhov kev ua tau zoo tshaj plaws ntawm cov khoom siv polymer, hloov dua tshiab ntawm 92%, tau ua cov yam ntxwv tseem ceeb tshaj plaws ntawm ntau daim ntawv thov.
Cov huab cua tiv thaiv ntawm PMMA kuj yog qhov thib ob rau tsis muaj nyob hauv cov huab cua sib txawv, uas yog qhov ntau dua li cov PC, PA thiab lwm cov plastics. Tsis tas li ntawd, tus xaum tawv tawv ntawm PMMA tuaj yeem ncav cuag 2 leej, uas yog ntau dua li lwm cov txheej txheem zoo li lub PC, thiab muaj qhov zoo ntawm cov qauv pov tseg.
Vim tias nws cov yam ntxwv zoo, PMMA tau siv dav hauv kev siv tsheb, khoom siv hluav taws xob, cov khoom siv khoom siv, tsim khoom thiab tsev kho mob thiab lwm thaj chaw.
Cov ntawv thov PMMA hauv tshav puam
Nyob rau hauv dav dav, PMMA nyob rau hauv lub tsheb Taillight, Dashboard teeb, tsuas yog siv nyob rau hauv lub tswv yim iav, tsuas yog siv rau hauv pob tshab, translucent thiab ntau cov liaj teb thiab lwm thaj teb.
1, PMMA siv nyob rau hauv lub tsheb tailflights
Lub tsheb teeb tau muab faib ua cov taub hau thiab cov ntaub ntawv pob tshab tau siv rau cov ntu xws li cov teeb meem. Lub teeb taws thiab huab teeb ntxoov ntxoo Siv Polycarbonate PC cov ntaub ntawv siv feem ntau, thaum lub tsheb tsav tsheb ntawm cov kev cuam tshuam ntawm cov teeb meem kev xav tau tseem ceeb. Tab sis PC siv rau lub taub hau kuj tseem muaj cov thev naus laus zis, kev laus siab, kev laus yooj yim thiab lwm yam shortcomings.
Tailights feem ntau tig cov cim, cov teeb nres yog qhov yuav tsum tau muaj tsawg, feem ntau yog siv cov pa hluav taws xob, yog li cov pa hluav taws xob, yog li huab cua ua kom muaj huab cua tsis zoo , High Streight Wardness, yog lub npog ntsej muag, Reveyor, qhia lub teeb ntawm cov khoom zoo. Vim nws lub siab tawv, PMMA muaj qhov zoo khawb tiv thaiv thiab tuaj yeem siv ncaj qha tsis muaj kev tiv thaiv sab nraud thaum siv raws li lub teeb sab nraud kom phim daim iav. Lub teeb tawg PMMA muaj cov yam ntxwv zoo tshaj plaws thiab yooj yim kom ua tiav cov khoom siv teeb pom kev zoo, uas yog ib qho ntawm cov ntaub ntawv tseem ceeb hauv Taillight daim ntawv thov.
2, PMMA rau Dashboard npog
Lub Dashids daim npog feem ntau yog lub luag haujlwm ntawm kev tiv thaiv cov twj paj nruag thiab saib cov ntaub ntawv ntsuas kom raug. Cuab Yeej Vaj Huam Sib Luag feem ntau txhaj tshuaj, PMMA yog ntau, muaj zog ruaj khov, nyob rau hauv lub hnub ci hluav taws xob, nyob rau hauv lub cav kub tsis deformation, nyob rau hauv lub sij hawm zoo siab tsis deformation , Tsis swb, tsis cuam tshuam rau qhov tseeb ntawm qhov ntsuas.
3, cov kab ntawv sab nraud thiab cov ntawv txiav
Cov kem tsheb tau muab faib ua ABC kem, nws cov kev xav tau zoo, feem ntau yog cov xim cua daj cua dub (PMMA cov xim pleev xim kub, PMMA + ABS OB CHAV EXTRUSION cov txheej txheem, thiab cov phiaj xwm PMMA nyuaj. Piv nrog cov tshuaj tsuag cov tshuaj tsuag, PMMA tuaj yeem tshem tawm cov txheej txheem txau, ntau tus nqi ua phooj ywg, thiab maj mam dhau los ua cov phiaj xwm tseem ceeb.
4, PMMA yog siv rau cov teeb sab hauv
Sab hauv lub teeb suav nrog kev nyeem cov teeb thiab cov teeb meem huab tais. Kev nyeem teeb yog ib feem ntawm lub tsheb sab hauv lub teeb pom kev zoo, feem ntau mounted rau sab xub ntiag lossis nraub qaum. Txhawm rau kom tiv thaiv lub teeb kom muaj kuab paug, nyeem cov teeb meem uas muaj lub teeb pom kev zoo, siv matte lossis pot daws teeb meem pc.
Lub teeb huab cua yog hom teeb pom kev zoo uas tuaj yeem tsim qhov chaw xis nyob thiab txhim kho lub siab. Lub teeb coj cov strips siv nyob rau hauv ambient lub teeb tau muab faib ua ob hom: mos thiab tawv raws li lawv cov qauv. Kev qhia nyuaj lub teeb yog qhov nyuaj, tsis tuaj yeem khoov, feem ntau los ntawm kev txhaj tshuaj molding los yog cov khoom siv PMMA, PC thiab lwm yam ntaub ntawv nrog pob tshab.
5, PMMA yog siv nyob rau hauv lub tsev saib lub tsev nyob
Lub ntsej muag saib daim iav pom ntau yuav tsum muaj cov gloss thiab dub ci ci, thaum xav tau kev cuam tshuam ntau zog, khawb tiv thaiv thiab huab cua tiv thaiv. Raws li cov duab ntawm daim iav plhaub feem ntau yog curved, nws yog ib qho yooj yim los ua kev ntxhov siab, yog li siv tau cov machining ua tau zoo. Cov txheej txheem pa tawm tau cov duab tshuaj txau me, tab sis cov txheej txheem muaj txau dawb, feem ntau ntawm no siv cov ntaub ntawv PMMA, kom tau raws li kev sim ua kom tiav thiab lwm yam Tej yaam num.
Qhov saum toj no yog cov ntawv thov PMMA nyob rau hauv lub tsheb tsheb teb, feem ntau cuam tshuam nrog Options lossis tsos, PMMA ntxiv ntau ntxiv rau lub tsheb teb.
