1. Plexiglass imapangidwa ndi polymethyl methacrylate, ndipo polymethyl methacrylate ili ndi gulu la polar methyl, lomwe lili ndi katundu wamphamvu wa hygroscopic.Mayamwidwe amadzi nthawi zambiri amayenera kukhala owuma pa pepala la acrylic, ndipo zofunikira kuti ziume ndi 78. Ziume pa °C-80 °C kwa 5-6h.
2. Plexiglass ndi polima wosaoneka, shrinkage osiyanasiyana akuchepa, zambiri mu osiyanasiyana 0.45% -0.9, kotero amapereka mikhalidwe yabwino akamaumba mwatsatanetsatane kupanga akiliriki, ndipo zambiri anapanga.Zonse ndi zolondola kwambiri.
3. mitundu yosinthira ya polymethyl methacrylate ku kutentha kozungulira ilibe madzi wamba, koma imakhala ndi madzi osakhala a Newtonian.Chifukwa chake, pa kutentha kwakukulu, kusungunuka kwa plexiglass kudzachepa.Ichi ndi plexiglass.Kuzindikira kwambiri kutentha.
4. Kutentha kwa plexiglass pakuyenda nthawi zambiri kumakhala pafupifupi 150 ° C, koma pamene plexiglass iyamba kuwola, kutentha kumakhala kopambana 270 ° C, kotero kumakhala kosavuta kwambiri pakusintha kwa kutentha, sikungatero. kukhudzidwa Chopangidwa ndi chikoka cha kutentha, kutentha kwambiri kukana ndi khalidwe la plexiglass.
5. plexiglass imakhalanso ndi ntchito yabwino yodulira, imatha kukonzedwa ndi kudula kwa laser pansi pa kukula kwabwino, kosavuta komanso kwapamwamba, mbaliyi ilibe galasi, kotero kuti acrylic akhoza kupirira kutentha kwakukulu ndi kutentha kwapansi.Ogula sayenera kudandaula za kutentha panthawi yopanga.
