MMA (Methyl Methacrylate): Cov Monomer Tseem Ceeb rau Cov Polymers Ua Haujlwm Zoo
Cov Ntawv Thov Tseem Ceeb
Hauv kev lag luam yas, PMMA siv dav rau kev tsim cov ntawv pob tshab, cov raj, thiab cov cuab yeej kho qhov muag vim nws cov khoom siv kho qhov muag zoo heev. Nws muaj kev pob tshab siab, qis refractive index, thiab tiv taus UV zoo heev, ua rau nws tsim nyog rau cov ntawv thov xws li cov paib, cov rooj tso saib, lub teeb tsheb, thiab cov ntaub thaiv dav hlau. Tsis tas li ntawd, PMMA qhov kev tiv thaiv tshuaj lom neeg zoo thiab lub zog kho tshuab ua rau nws zoo tagnrho rau cov khoom siv ua zaub mov thiab cov khoom siv kho mob.
Hauv kev lag luam pleev xim thiab nplaum, MMA siv los ua ntau yam resins ua tau zoo. Cov resins no muaj kev nplaum zoo heev, tiv taus huab cua, thiab tiv taus tshuaj lom neeg, ua rau lawv siv dav hauv kev pleev xim rau vaj tse, kev pleev xim rau tsheb, thiab kev kaw cov khoom siv hluav taws xob. Cov nplaum MMA, uas paub txog lawv cov kev kho sai thiab muaj peev xwm sib txuas tau zoo, feem ntau siv rau kev sib txuas ntoo, hlau, thiab yas.
Hauv kev lag luam khoom siv kho qhov muag, MMA yog cov khoom siv tseem ceeb rau kev tsim cov fibers kho qhov muag thiab cov iav tsom iav. Nws cov khoom siv kho qhov muag zoo tshaj plaws thiab kev tiv taus huab cua ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv kho qhov muag, suav nrog cov khoom siv sib txuas lus fiber optic thiab cov iav tsom iav ua haujlwm siab. Tsis tas li ntawd, MMA siv rau hauv kev tsim cov teeb qhia thiab cov sensors kho qhov muag.
Hauv kev lag luam composites, MMA yog siv los tsim cov methyl methacrylate resin-based composites. Cov composites no muaj zog heev, tsis muaj zog, thiab tiv taus corrosion zoo heev, ua rau lawv siv dav hauv aerospace, automotive, thiab cov khoom siv kis las. Piv txwv li, MMA-based composites yog siv rau hauv tis dav hlau, lub cev tsheb, thiab cov golf clubs.
