Iyini i-Polycarbonate?
I-Polycarbonate (PC) iyi-polymer material esetshenziswa kakhulu embonini yamakhemikhali futhi ingenye yezinto ezithandwayo ezimbonini eziningi ngenxa yezakhiwo zayo ezihlukile zomzimba namakhemikhali. Kulesi sihloko, sizohlaziya ngokuningiliziwe ukwakheka kanye nezakhiwo ze-Polycarbonate kanye nezinhlobonhlobo zayo zezicelo.
1. Ukwakheka kwamakhemikhali kanye nesakhiwo se-polycarbonate
I-Polycarbonate ikilasi le-bisphenol A (BPA) namaqembu e-carbonate ngokusabela kwe-polycondensation okukhiqizwa i-polymer eqondile. Iketango layo lamangqamuzana liqukethe inani elikhulu lamaqembu e-carbonate (-O-CO-O-), lesi sakhiwo sinikeza izinto ze-polycarbonate ukumelana nokushisa okuhle kakhulu, ukucaca kanye nokumelana nomthelela. Ukuzinza kwamakhemikhali e-polycarbonate kuyenza ikwazi ukugcina izakhiwo zayo zingashintshiwe ezindaweni ezidlulele, okwenza ibe yimpahla ehlala isikhathi eside.
2. Izakhiwo ezibalulekile ze-polycarbonate
I-Polycarbonate material yaziwa ngezakhiwo zayo eziphakeme zomzimba. Inokumelana nomthelela ophezulu kakhulu, izikhathi ezingu-250 kunengilazi evamile, okwenza i-polycarbonate idume ezinhlelweni ezidinga amandla aphezulu kanye nokumelana nomthelela. I-Polycarbonate inokumelana nokushisa okuhle kakhulu, okuhlala kuzinzile ukusuka ku--40 ° C kuya ku-120 ° C, okwenza ukuthi yenze kahle ezindaweni ezishisa kakhulu. I-Polycarbonate iphinde ibe nokukhanyela okuhle kwe-optical, idlulisa ngaphezu kwamaphesenti angu-90 okukhanya okubonakalayo, ngakho-ke ivame ukusetshenziswa ekwenzeni ama-lens optical kanye nesembozo esisobala.
3. Izindawo zokufaka isicelo ze-polycarbonate
Ngenxa yezakhiwo eziyingqayizivele ze-polycarbonate materials, isetshenziswa kabanzi ezimbonini ezihlukahlukene. Embonini yezokwakha, i-polycarbonate ivame ukusetshenziselwa ukwenza amapaneli akhanyayo, izinto zokuphahla kanye namaphaneli e-acoustic. Ukumelana nomthelela wayo okuhle kakhulu nokungafihli lutho kwenza ibaluleke kakhulu kulezi zindawo. Emkhakheni kagesi kanye nogesi, i-polycarbonate isetshenziselwa ukwenza izingxenye ze-elekthronikhi, izindlu zemishini yasendlini namakesi ebhethri ngenxa yokumelana nokushisa kwayo kanye nezakhiwo zokuvala ugesi. I-Polycarbonate nayo isetshenziswa kabanzi embonini yezimoto, ikakhulukazi kumalambu, amaphaneli wezinsimbi namafasitela. Okubaluleke nakakhulu, i-polycarbonate iphinde isetshenziswe kabanzi emkhakheni wemishini yezokwelapha, njengamasirinji, okokusebenza kwe-dialysis namathuluzi okuhlinza, njll. Lezi zinhlelo zokusebenza zibonga ukungewona ubuthi nokuhambisana kwe-biocompatibility yezinto ze-polycarbonate.
4. I-Polycarbonate Enobungani Nemvelo futhi Esenziwe Kabusha
Nakuba i-polycarbonate iyinto ehlala isikhathi eside futhi eguquguqukayo, i-bisphenol A (BPA) ehilelekile ekukhiqizeni kwayo ibangele impikiswano ethile yezemvelo. Njengoba ubuchwepheshe buthuthuka, kuye kwathuthukiswa imikhiqizo eminingi ye-polycarbonate evikela imvelo enciphisa umthelela emvelweni. Ukugaywa kabusha kwe-polycarbonate nakho kancane kancane kutholwa ukunakwa, futhi ngenqubo yokuvuselela, udoti we-polycarbonate izinto zingashintshwa zibe yimikhiqizo emisha ukuze kuqhutshekwe nokunciphisa udoti wezinsiza.
Isiphetho
Iyini i-polycarbonate? Kuyimpahla ye-polymer enezici ezihlukahlukene eziphakeme, futhi isetshenziswa kakhulu ekwakheni, izinto zikagesi nezikagesi, ezezimoto, ezokwelashwa kanye neminye imikhakha ngenxa yokumelana nomthelela, ukumelana nokushisa, ukucaca kanye nokuzinza kwamakhemikhali. Ngokuqwashisa okwandayo kokuvikelwa kwemvelo, ukugaywa kabusha kwe-polycarbonate kuthuthukiswa kancane kancane. I-Polycarbonate iyinto esebenzayo futhi enamandla okuthuthukiswa okuqhubekayo.
