Polycarbonate ndi chiyani?
Polycarbonate (PC) ndi chinthu chopangidwa ndi polima chomwe chimagwiritsidwa ntchito kwambiri pamakampani opanga mankhwala ndipo ndi chimodzi mwazinthu zomwe zimakondedwa kwambiri m'mafakitale ambiri chifukwa cha mawonekedwe ake apadera amthupi komanso mankhwala. M'nkhaniyi, tisanthula mwatsatanetsatane kapangidwe ka polycarbonate ndi mawonekedwe ake osiyanasiyana.
1. Kapangidwe kake ndi kapangidwe ka polycarbonate
Polycarbonate ndi gulu la bisphenol A (BPA) ndi magulu a carbonate kudzera munjira ya polycondensation yopangidwa ndi polima mzere. Unyolo wake wa mamolekyulu uli ndi magulu ambiri a carbonate (-O-CO-O-), kapangidwe kameneka kamapereka zinthu za polycarbonate kwambiri kukana kutentha, kuwonekera komanso kukana mphamvu. Kukhazikika kwamankhwala a polycarbonate kumathandizira kuti zinthu zake zikhale zosasinthika m'malo ovuta kwambiri, ndikupangitsa kuti ikhale yolimba kwambiri.
2. Zinthu zazikulu za polycarbonate
Zinthu za polycarbonate zimadziwika ndi mawonekedwe ake apamwamba. Ili ndi kukana kwakukulu kwambiri, nthawi 250 kuposa yagalasi wamba, yomwe imapangitsa kuti polycarbonate ikhale yotchuka pamapulogalamu omwe amafunikira mphamvu yayikulu komanso kukana kwamphamvu. Polycarbonate imakhala ndi kutentha kwabwino kwambiri, yokhazikika kuchokera -40 ° C mpaka 120 ° C, yomwe imalola kuti izichita bwino m'malo otentha kwambiri. Polycarbonate imakhalanso ndi kuwala kowoneka bwino, kutulutsa kuwala kopitilira 90 peresenti ya kuwala kowoneka bwino, kotero nthawi zambiri imagwiritsidwa ntchito popanga magalasi owoneka bwino ndi zophimba zowonekera.
3. Malo ogwiritsira ntchito polycarbonate
Chifukwa chapadera cha zipangizo za polycarbonate, zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. M'makampani omanga, polycarbonate imagwiritsidwa ntchito popanga mapanelo owala, zida zofolera ndi ma acoustic panels. Kukana kwake kwakukulu komanso kuwonekera kwake kumapangitsa kukhala kofunikira kwambiri m'malo awa. M'gawo lamagetsi ndi zamagetsi, polycarbonate imagwiritsidwa ntchito popanga zida zamagetsi, zida zapanyumba ndi ma batire chifukwa cha kukana kutentha komanso kutsekereza magetsi. Polycarbonate imagwiritsidwanso ntchito kwambiri m'makampani opanga magalimoto, makamaka pazowunikira, mapanelo a zida ndi mazenera. Chofunika kwambiri, polycarbonate imagwiritsidwanso ntchito kwambiri pazida zamankhwala, monga ma syringe, zida za dialysis ndi zida zopangira opaleshoni, ndi zina zotere. Ntchitozi zikomo chifukwa chosagwiritsa ntchito poizoni ndi biocompatibility ya zida za polycarbonate.
4. Wokonda zachilengedwe ndi Polycarbonate Yowonjezeredwa
Ngakhale polycarbonate ndi chinthu cholimba komanso chosunthika, bisphenol A (BPA) yomwe idakhudzidwa ndi kupanga kwake idayambitsa mkangano pazachilengedwe. Pamene teknoloji ikupita patsogolo, zinthu zambiri zomwe zimagwirizana ndi chilengedwe za polycarbonate zapangidwa zomwe zimachepetsa kuwononga chilengedwe. Kubwezeretsanso kwa polycarbonate kumayambanso kuyang'aniridwa pang'onopang'ono, ndipo kudzera munjira yokonzanso, zida za polycarbonate zitha kusinthidwa kukhala zatsopano kuti zichepetse zinyalala zazinthu.
Mapeto
Kodi polycarbonate ndi chiyani? Ndi zinthu za polima zomwe zimakhala ndi makhalidwe apamwamba, ndipo zimagwiritsidwa ntchito kwambiri pomanga, zipangizo zamagetsi ndi zamagetsi, magalimoto, zamankhwala ndi zina chifukwa cha kukana kwake, kukana kutentha, kuwonekera komanso kukhazikika kwa mankhwala. Ndi kuzindikira kochulukira kwa chitetezo cha chilengedwe, kukonzanso kwa polycarbonate kukulitsidwa pang'onopang'ono. Polycarbonate ndi chinthu chomwe chili chothandiza komanso chili ndi kuthekera kwachitukuko chokhazikika.
