Qhov Tseem Ceeb Qhov txawv - Acrylic vs Plexiglass
Cov ntsiab lus Acrylic thiab Plexiglass feem ntau siv sib hloov rau cov ntawv yas ua los ntawm cov polymer tau los ntawm esters ntawm methacrylic acid. Qhov sib txawv tseem ceeb ntawm Acrylic thiab Plexiglass yog Plexiglass yog lub npe ntawm cov ntawv acrylic. Acrylic latices tuaj yeem muab tau los ntawm esters ntawm acrylic acid lossis methacrylic acid. Acrylic elastomers tau raug suav hais tias yog 'cov roj hmab tshwj xeeb' vim lawv cov khoom tshwj xeeb, piv txwv li, muaj cov pob txha tsis txaus polymer, tsis zoo li ntau lwm yam hu ua roj hmab lub hom phiaj. Vim tias cov acrylic polymers tuaj yeem tiv taus qhov kub thiab txias, UV, ozone, oxygen, thiab lwm yam. Cov ntsiab lus ntxiv ntawm acrylic thiab Plexiglass tau tham hauv kab lus no.
YAcrylic yog dab tsi?
Acrylic elastomers yog cov roj hmab tshwj xeeb uas muaj cov khoom zoo heev xws li tiv thaiv qhov kub thiab txias (> 150 ° C), UV, ozone, oxygen, sulfur-cov kabmob roj thiab roj, thiab qhov ntev stability hauv aliphatic hydrocarbons. Feem ntau ntawm cov hom phiaj elastomers xws li cov roj hmab ntuj, SBR, thiab lwm yam, tsis muaj cov khoom zoo li no. Yog li ntawd, tag nrho cov khoom no tau ua rau acrylics muaj txiaj ntsig zoo hauv kev siv hauv kev lag luam tsheb thiab kev tsim cov roj txias hoses, cov ntsaws ruaj ruaj, rear qag seals, thiab lwm yam. hydrogen txuas nrog alternate carbon atoms nyob rau hauv lub polymer saw.
Daim duab 01: Xim Acrylics
Qhov yooj yim acrylic elastomer yog poly (ethyl acrylate), uas muaj kev txwv tsis pub siv vim nws qhov kub hloov pauv iav (-15 ° C). Acrylic latices yog siv ntau ntau rau qee yam kev siv xws li binders rau textile fibers thiab latex-based coatings. Tsis tas li ntawd, acrylic latices yog siv los ua ion-exchange resins, rau dispersion ntawm pigments nyob rau hauv cov xim los yog xis mas, thiab aggregate tshem tawm hais thaum lub sij hawm kev kho dej khib nyiab.
Acrylic cov khoom feem ntau yog tsim los ntawm cov txheej txheem extrusion lossis txheej txheem casting. Txoj kev Extrusion yog pheej yig dua, tab sis cov txheej txheem muaj qee qhov tsis zoo xws li qib siab dua ntawm impurities thiab tsawg hardness thaum piv rau cov khoom cam khwb cia.
Plexiglass yog dab tsi?
Plexiglass yog ib hom ntawm acrylic elastomer ua los ntawm poly (methyl methacrylate). Cov khoom Plexiglass yog tsim los ntawm ob qho tib si extrusion thiab casting txheej txheem. Cov khoom siv extruded yog qhov nyuaj tsawg dua thaum piv rau cov khoom siv casting; yog li ntawd, lawv yog cov txheej txheem yooj yim. Txawm li cas los xij, qhov siab tshaj plaws kev pabcuam kub ntawm extruded Plexiglass yog qis dua li ntawm cov khoom siv Plexiglass. Thaum piv rau cov qauv acrylics, Plexiglass cov khoom lag luam raug nqi ntau vim yog siab purity thiab cov khoom zoo heev.
Daim duab 02: Plexiglass
Plexiglass acrylics qhia tau zoo heev tiv taus nag, cua daj cua dub, huab cua siab, thiab cua sov. Tsis tas li ntawd, cov nplooj ntawv yog tawg-resistant thiab tuaj nyob rau hauv meej thiab kuj muaj ntau yam xim nyob ntawm seb lawv daim ntawv thov. Cov khoom lag luam Plexiglass yog siv los ua cov khoom siv raw los tsim lub dav hlau cabin qhov rais, lub computer saib, thiab cov lus qhia, cov qauv glazing, suab nrov teeb meem, tsheb qhov chaw, thiab lwm yam. Cov khoom lag luam muaj nyob rau hauv cov ntawv corrugated, films, molding compounds, multi-skin sheets, rods thiab tubes, solid sheets, thiab tubes.
Qhov txawv ntawm Acrylic thiab Plexiglass yog dab tsi?
Acrylic vs Plexiglass |
|
| Acrylic yog ib lub npe ntawm ib qho elastomer, qhov Plexiglass yog lub npe lag luam rau acrylic elastomer. | Standard acrylics feem ntau yog tsim los ntawm txoj kev extrusion, uas yog tus nqi qis. Plexiglass los xij yog tsim los ntawm ob qho tib si casting thiab extrusion txheej txheem. |
Summary – Acrylic vs Plexiglass
Acrylic thiab Plexiglass raug xa mus rau tib pab pawg elastomers. Ib qho acrylic yog ib pawg ntawm elastomers. Plexiglass yog PMMA, uas tuaj nyob rau hauv pawg ntawm acrylic. Acrylic elastomers yog lub npe hu ua cov roj hmab tshwj xeeb vim lawv cov huab cua zoo heev, tiv thaiv tshav kub, thiab hnyav hnyav. Yog li, lawv tau siv rau hauv ntau daim ntawv thov suav nrog hauv cov khoom siv dav hlau, cov khoom siv tsheb, cov hlua khi, cov resins, thiab lwm yam.
