Methyl Methacrylate (MMA) yog ib qho organic compound nrog cov tshuaj formula C₅H₈O₂, uas yog siv los ua monomer rau cov iav organic, thiab dav siv nyob rau hauv thaj chaw ntawm resins, plastics, thiab coatings.
Cov khoom ntawm Methyl Methacrylate (MMA)
Methyl Methacrylate (MMA), alias methyl isobutenoate lossis methyl methyl ester, yog cov kua tsis muaj xim nrog cov khoom nram qab no:
Lub cev muaj zog
MMAyog ib qho xim tsis muaj xim, pob tshab kua nyob rau hauv chav tsev kub thiab siab nrog ib tug irritating tsw. Nws qhov ceev yog 0.942 g / cm³, kub taw tes yog li 100 degree, flash point yog 10 degree, nws yog flammable thiab volatile.MMA muaj tsawg solubility nyob rau hauv dej, tab sis yog miscible nrog feem ntau organic solvents, xws li cawv, ketones thiab esters.
Chemical Properties
MMA molecule muaj ob daim ntawv cog lus thiab ib pawg ester thiab muaj kev ua haujlwm siab. Nws tau nkag mus rau cov dawb radical polymerization los tsim polymethyl methacrylate (PMMA).MMA kuj tuaj yeem koom nrog cov tshuaj tiv thaiv copolymerization, copolymerizing nrog lwm cov monomers xws li styrene thiab acrylonitrile los tsim cov copolymer nrog cov khoom sib txawv.MMA yog resistant rau lub teeb, tshav kub, thiab tshuaj reagents, tab sis nws yuav ntev ntev rau lub teeb los yog decomposes. ntawm lub sijhawm.
methyl methacrylate siv
- Adhesives: MMA-raws li polymers muab kev sib raug zoo, tiv thaiv tshav kub, thiab ua haujlwm ntev rau kev siv tsheb, hluav taws xob, thiab kev tsim kho.
- Coatings: Nws siab clarity, UV tsis kam, thiab nto hardness ua MMA lug siv nyob rau hauv kev tiv thaiv thiab hniav txheej rau hlau, ntoo, thiab industrial nto.
- Resins: MMA yog thawj monomer rau tsim acrylic thiab tshwj xeeb resins siv nyob rau hauv yas, inks, thiab composite cov ntaub ntawv.
Kev ruaj ntseg zoo, ntau yam kev siv
Vim nws txoj kev ua tau zoo, methyl methacrylate (MMA) tau siv ntau dua hauv kev tsim cov khoom siv nrog cov pob tshab siab thiab ua haujlwm rau qhov chaw hnyav. Kev lag luam suav nrog kev kho tsheb, kev siv tshuab, ntim khoom, thiab cov khoom siv hauv tsev.
Gneebio ua kom ntseeg tau tias txhua pawg ntawm MMA ua tau raws li cov qauv zoo thoob ntiaj teb, muab kev ua kom huv si zoo ib yam thiab muaj kev ruaj ntseg tshwj xeeb los txhawb ntau yam kev siv hauv qab.
