Zamagetsi Ndi Zakuthupi Za Plexiglass

Polymethyl methacrylate ili ndi mphamvu zochepa zamagetsi kuposa mapulasitiki omwe si a polar monga polyolefins ndi polystyrene chifukwa cha gulu la polar methyl ester pambali pa unyolo waukulu.Polarity wa gulu la methyl ester si lalikulu kwambiri, ndipo polymethyl methacrylate akadali ndi zabwino dielectric ndi magetsi insulating katundu.Ndizofunikira kudziwa kuti polymethyl methacrylate komanso pulasitiki yonse ya acrylic ili ndi kukana kwa arc.Pansi pa zochita za arc, pamwamba sipanga njira zopangira mpweya komanso zochitika za arc track.20 ° C ndi kutentha kwachiwiri, komwe kumayenderana ndi kutentha komwe gulu la methyl ester limayamba kusuntha.Pansi pa 20 ° C, gulu la methyl ester lili m'malo oundana, ndipo mphamvu zamagetsi zazinthuzo zimawonjezeka kuposa 20 ° C.

Polymethyl methacrylate ili ndi zida zamakina zabwino zonse ndipo ili patsogolo pa mapulasitiki omwe amagwiritsidwa ntchito nthawi zonse.Kulimba kwamphamvu, kulimba kwamphamvu, kukanikizana ndi mphamvu zina ndizokwera kuposa za polyolefins, komanso zapamwamba kuposa za polystyrene ndi polyvinyl chloride.Kulimba kwamphamvu ndikovuta.Komanso bwino pang'ono kuposa polystyrene.Mapepala ochuluka a polymethyl methacrylate (monga pepala la plexiglass) ali ndi makina apamwamba kwambiri monga kutambasula, kupindika ndi kuponderezana, ndipo amatha kufika pamlingo wa mapulasitiki a engineering monga polyamide ndi polycarbonate.
