1. Lub plexiglass yog ua los ntawm polymethyl methacrylate, thiab cov polymethyl methacrylate muaj ib tug polar side methyl pawg, uas muaj zog hygroscopic khoom.Kev nqus dej feem ntau yuav tsum tau khaws cia kom qhuav ntawm daim ntawv acrylic, thiab qhov xwm txheej yuav tsum tau ziab yog 78. Qhuav ntawm ° C-80 ° C rau 5-6h.
2. Plexiglass yog ib qho tsis pom cov polymer, nws qhov shrinkage ntau yog txo, feem ntau nyob rau hauv thaj tsam ntawm 0.45%-0.9, yog li nws muab cov kev mob zoo rau molding precision nyob rau hauv zus tau tej cov acrylic, thiab feem ntau yog tsim.Lawv tag nrho yog heev meej.
3. Kev hloov pauv ntawm polymethyl methacrylate rau ambient kub tsis muaj fluidity zoo tib yam, tab sis muaj non-Newtonian fluidity.Yog li ntawd, nyob rau hauv kub kub, solubility ntawm plexiglass yuav txo.Qhov no yog plexiglass.Heev rhiab heev rau qhov kub thiab txias.
4. qhov kub ntawm lub plexiglass nyob rau hauv tus txheej txheem ntawm ntws yog feem ntau nyob ib ncig ntawm 150 ° C, tab sis thaum lub plexiglass pib decompose, qhov kub ntawm lub siab tshaj 270 ° C, yog li nws tseem hloov tau heev nyob rau hauv cov nqe lus ntawm kub hloov, yuav tsis. raug cuam tshuam Ua los ntawm kev cuam tshuam ntawm qhov kub thiab txias, kub tsis kam yog cov yam ntxwv ntawm plexiglass.
5. plexiglass kuj muaj kev ua haujlwm zoo, tuaj yeem ua tiav los ntawm laser txiav raws li qhov loj me, yooj yim thiab zoo, cov yam ntxwv no tsis muaj iav, yog li acrylic tuaj yeem tiv taus qhov kub thiab txias ib puag ncig.Cov neeg siv khoom tsis tas yuav txhawj xeeb txog qhov kub thiab txias thaum lub sijhawm tsim khoom.
