Kodi Polycarboname ndi chiyani?
Polycarbonate (PC) ndi nkhani yogwiritsidwa ntchito kwambiri polymer, pamakampani okonda kugwiritsa ntchito mankhwala ndipo ndi amodzi mwa zinthu zomwe amakonda m'mafakitale ambiri chifukwa cha zinthu zawo zapadera komanso zamankhwala. Munkhaniyi, tikambirana mwatsatanetsatane kapangidwe ka polycarbonate komanso mitundu yosiyanasiyana.
1. Kupanga kwamankhwala ndi kapangidwe ka polycarbonate
Polycarbonate ndi gulu la bisphenol A (BPA) ndi magulu a carbonate kudzera mu ma polycometivetion chizolowezi chomwe chidapangidwa ndi polymer polymer. Chinsalu chake chimakhala ndi magulu ambiri a carbonate (-O-co-o-), kapangidwe kameneka kamapereka kukana kwamphamvu kwa polybacbonate, kuwonekera komanso kukana. Kukhazikika kwamankhwala kwa polycarbote kumapangitsa kuti malo ake akhale m'malo otukuka, kumapangitsa kukhala zinthu zolimba.
2. Katundu wa polycarbonate
Zinthu za Polycarbonate zimadziwika chifukwa cha kukhala zinthu zake zapamwamba. Ili ndi vuto lalikulu kwambiri, nthawi 250 zagalasi wamba, zomwe zimapangitsa Polybarbonate wodziwika mu mapulogalamu omwe amafunikira kulimba kwambiri komanso kukana. Polycarbonate imayamba kukana kutentha, khola lokhazikika kuchokera -40 ° C mpaka 120 ° C, zomwe zimapangitsa kuti zikhale bwino kwambiri. Polycarbote nawonso amangokhala ndi mzimu wowoneka bwino, kufalitsa zoposa 90 peresenti ya kuwala kowoneka, kotero nthawi zambiri kumagwiritsidwa ntchito popanga magalasi owala komanso owoneka bwino.
3. Magawo a Pulcarbonate
Chifukwa cha malo apadera a polycacbonate, imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Mu makampani omanga, polycarbonate imagwiritsidwa ntchito popanga mapanelo owala, zida zodetsa ndi mapanelo acoustic. Kutsutsana kwake kwakukulu komanso kuwonekera kumapangitsa kuti zikhale zofunika m'mbali izi. Mu magetsi ndi zamagetsi, polycarbonate imagwiritsidwa ntchito popanga zigawo zamagetsi, nyumba zapakhomo zamagetsi ndi ma batri chifukwa cha kukana kwa kutentha ndi zida zamagetsi. Polycarbonate imagwiritsidwanso ntchito kwambiri m'malo ogulitsa akhama, makamaka kwa anyani a nyale, magwiridwe a zida ndi mawindo. Chofunika koposa, polycarbonate imagwiritsidwanso ntchito kwambiri pankhani ya zida zamankhwala, monga ma syrine, zida zama dialysis ndi zida zopangira opaleshoni ndi zopanda nzeru za polycacbonation.

Ngakhale polybacate ndizinthu zolimba komanso zosinthasintha, bisphenol a (bpa) omwe amakhudzidwa ndi kupanga chilengedwe chinayambitsa mkangano wachilengedwe. Monga ukadaulo umapita patsogolo, zochulukirapo komanso zochulukirapo zachilengedwe zapangidwa kuti zimachepetsa zomwe zingakulepheretseni zachilengedwe. Kubwezeretsanso kwa Polycarbonate kumawunikiranso pang'onopang'ono, ndipo kudzera munjira yobwezeretsanso, zinyalala za polycacbonate zitha kusinthidwa kukhala zinthu zatsopano kuti zitheke kuwononga ndalama.
Mapeto
Kodi Polycarboname ndi chiyani? Ndi nkhani ya polymer yokhala ndi mikhalidwe yapamwamba, ndipo imagwiritsidwa ntchito kwambiri pomanga, zamagetsi ndi zamagetsi, zamagetsi, zolimbana ndi kuwonekera kwamankhwala. Ndi kuzindikira kukulira zachilengedwe, kubwezeretsa kwa Polycarbonate kukulimbikitsidwa pang'onopang'ono. Polycarbonate ndizinthu zomwe zili zothandiza ndipo zimatha kukula.
