Mankhwala katundu
Polycarbonate imagonjetsedwa ndi zidulo, mafuta, kuwala kwa ultraviolet ndi alkalis amphamvu.
Thupi katundu
Polycarbonate ndi yopanda mtundu komanso yowonekera, yosatentha, yosagwira, yosagwira ntchito, yoletsa moto,
Iwo ali wabwino makina katundu wabwinobwino ntchito kutentha.
Poyerekeza ndi polymethyl methacrylate yokhala ndi magwiridwe antchito ofanana, polycarbonate imakhala ndi kukana bwinoko.
Mlozera wapamwamba wa refractive, magwiridwe antchito abwino, UL94 V-2 retardant flame performance popanda zowonjezera.
Komabe, mtengo wa polymethyl methacrylate ndi wotsika,
Ndipo imatha kupanga zida zazikulu kudzera mu polymerization yochulukirapo.
Ndi kuchuluka kwa kupanga kwa polycarbonate,
Kusiyana kwamitengo pakati pa polycarbonate ndi polymethyl methacrylate kukucheperachepera.
Polycarbonate ikayaka, imatulutsa mpweya wa pyrolysis, ndipo pulasitiki imayaka ndi thovu, koma sichigwira moto.
Lawi lamoto limazimitsidwa likakhala kutali ndi gwero lamoto, limatulutsa fungo lochepa la phenol, lawi lamoto ndi lachikasu, lonyezimira lakuda,
Kutentha kumafika pa 140 ℃, kumayamba kufewa, ndipo kumasungunuka pa 220 ℃, komwe kumatha kuyamwa ma infrared spectrum.
Polycarbonate ili ndi kukana kovala bwino.
Zida zina za polycarbonate zomwe zimagwiritsidwa ntchito povala nthawi zambiri zimafunikira chithandizo chapadera chapamwamba.
