Qhov sib txawv tseem ceeb ntawm EMA thiab MMA monomer yog tias kev siv EMA monomer tuaj yeem ua rau tawg ntawm acrylic, qhov kev siv MMA monomer tuaj yeem ua kom acrylic ci thiab me ntsis slimy tab sis yuav tsis ua rau nws tawg..
EMA lossis Ethyl methacrylate monomer yog cov organic compound uas muaj cov tshuaj formula C2H5O2CC(CH3)=CH2. EMA los yog Methyl methacrylate monomer yog cov organic compound uas muaj cov tshuaj formula CH2=C (CH3) COOCH3. Ob lub monomers no muaj txiaj ntsig zoo hauv kev lag luam tshuaj pleev ib ce. Lawv yog ob hom monomer kua siv rau hauv daim ntawv thov acrylic. Txawm li cas los xij, kev siv MMA raug txwv los ntawm kev siv tsis ntev los no los ntawm FDA, txawm hais tias nws pheej yig dua li EMA monomer kua. Txawm li cas los xij, MMA monomer kua tuaj yeem muaj txiaj ntsig zoo hauv kev kho hniav thiab cov khoom siv kho mob: rau cov hniav txhaws, kho pob txha, thiab lwm yam.
EMA Monomer yog dab tsi?
EMA lossis Ethyl methacrylate monomer yog cov organic compound uas muaj cov tshuaj formula C2H5O2CC(CH3)=CH2. Nws yog cov kua uas tsis muaj xim, thiab nws yog suav tias yog ib qho monomer ntawm kev npaj acrylate polymers. Feem ntau, cov monomer no dhau los ua polymerization nyob rau hauv cov xwm txheej dawb-radical. Nws yog ib qho tseem ceeb kom paub tias acrylate esters tuaj yeem ua rau lub qhov muag ua rau khaus thiab ua rau dig muag.
Daim duab 01: Cov Qauv Tshuaj ntawm EMA Monomer
EMA monomer yog hom acrylic monomer kua uas muaj txiaj ntsig zoo hauv cov tshuab acrylic feem ntau. Cov monomer no suav hais tias yog methacrylic acid ethyl ester, thiab nws yog cov khoom tseem ceeb hauv feem ntau cov ntsia hlau acrylic monomers. Nws tshwm sim raws li cov xim tsis muaj xim, muaj kuab paug lom nrog cov ntxhiab tsw.
MMA Monomer yog dab tsi?
Methyl methacrylate monomer yog cov organic compound uas muaj cov tshuaj formula CH2=C (CH3) COOCH3. Nws tshwm sim raws li cov kua tsis muaj xim muaj cov methyl ester ntawm methacrylic acid, uas yog lub monomer ntawm kev tsim loj-scale poly (methyl methacrylate) los yog PMMA polymer.
Daim duab 02: Cov Qauv Tshuaj ntawm MMA Monomer
Muaj ntau txoj hauv kev tsim MMA monomer, xws li cyanohydrin txoj kev, methyl propionate txoj kev, ntau lawm ntawm propionaldehyde, los ntawm isobutyric acid, methyl acetylene txheej txheem, isobutylene txoj, thiab lwm yam.
Muaj ntau yam kev siv MMA monomers, xws li siv hauv kev tsim cov PMMA polymer, tsim cov copolymer methyl methacrylate-butadiene-styrene uas yog ib qho tseem ceeb raws li kev hloov kho rau PVC, ua raw khoom rau methacrylate, thiab lwm yam.
Qhov txawv ntawm EMA thiab MMA Monomer yog dab tsi?
EMS sawv cev rau ethyl methacrylate, thaum MMA sawv cev rau methyl methacrylate. Cov no yog cov kua monomer tseem ceeb hauv kev lag luam tshuaj pleev ib ce. Qhov sib txawv tseem ceeb ntawm EMA thiab MMA monomer yog tias kev siv EMA monomer tuaj yeem ua rau tawg ntawm acrylic, thaum siv MMA monomer tuaj yeem ua kom acrylic ci thiab me ntsis slimy tab sis yuav tsis ua rau nws tawg.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm EMA thiab MMA monomer hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – EMA vs MMA Monomer
Ethyl methacrylate monomer yog cov organic compound uas muaj cov tshuaj formula C2H5O2CC(CH3)=CH2, hos Methyl methacrylate monomer yog cov organic compound uas muaj cov tshuaj formula CH2=C(CH3)COOCH3. Cov no muaj txiaj ntsig zoo li cov kua dej monomer hauv kev lag luam tshuaj pleev ib ce. Qhov sib txawv tseem ceeb ntawm EMA thiab MMA monomer yog tias kev siv EMA monomer tuaj yeem ua rau tawg ntawm acrylic, thaum siv MMA monomer tuaj yeem ua kom acrylic ci thiab me ntsis slimy tab sis yuav tsis ua rau nws tawg.
