Yini i-polycarbonate?
I-Polycarbonate (PC) iyinto esetshenziswa nge-polymer embonini yamakhemikhali futhi ingenye yezinto ezithandwayo ezimbonini eziningi ngenxa yezakhiwo zayo ezihlukile nangamakhemikhali. Kulesi sihloko, sizokuhlaziya ngokuningiliziwe ukwakheka kanye nezakhiwo zePolycarbonate nezinhlobo zawo ezahlukahlukene zezicelo.
1. Ukwakheka kwamakhemikhali kanye nokwakheka kwePolycarbonate
I-Polycarbonate iyisigaba se-Bisphenol A (BPA) namaqembu e-carbonate ngokusabela kwe-polycondessation ekhiqizwe yi-polymer eqondile. I-molecula chain yayo iqukethe inani elikhulu lamaqembu e-carbonate (-O-co-o), lesi sakhiwo sinikeza impahla ye-polycarbonate ukushisa okuhle, ukucaca kanye nokumelana nomthelela. Ukuqina kwamakhemikhali i-polycarbonate kukwenza ukuthi kugcinwe izakhiwo zayo zingashintshiwe ezindaweni ezedlulele, okwenza kube yinto eqinile kakhulu.
2. Izici ezibalulekile zePolycarbonate
Izinto zePolycarbonate zaziwa ngezakhiwo zalo eziphakeme zenyama. Inokuphikiswa okuphezulu kakhulu, izikhathi ezingama-250 zokuthi ngengilazi ejwayelekile, eyenza i-polycarbonate ithambekele kuzinhlelo zokusebenza ezidinga amandla aphezulu kanye nokumelana nomthelela. I-Polycarbonate inokumelana kahle nokushisa okuhle kakhulu, okusele kusuka ku-40 ° C kuya ku-120 ° C, okuvumela ukuthi yenze kahle ezindaweni ezishisa kakhulu. I-Polycarbonate futhi inokubona okuhle okubonakalayo, ukudlulisela amaphesenti angaphezu kwangama-90 okukhanya okubonakalayo, ngakho-ke kuvame ukusetshenziselwa ukwenziwa kwamalensi abonakalayo kanye nesembozo esibonakalayo.
3. Izindawo zohlelo lokusebenza lwePolycarbonate
Ngenxa yezakhiwo ezihlukile ze-polycarbonate izinto, zisetshenziswa kabanzi ezinhlotsheni ezahlukahlukene. Embonini yezokwakha, i-polycarbonate ivame ukusetshenziswa ukwenza amaphaneli akhanyayo, izinto zophahla kanye namaphaneli e-acoustic. Ukumelana kwayo okuhle kakhulu kanye nokuvela obala kwenza kube yinto ebaluleke kulezi zindawo. Emkhakheni kagesi nogesi, i-polycarbonate isetshenziselwa ukwenza izakhi ze-elekthronikhi, izindlu ze-applical zasendlini kanye namacala ebhethri ngenxa yokumelana nokushisa kukagesi. I-Polycarbonate isetshenziswa kabanzi embonini yezimoto, ikakhulukazi ama-lambu, amaphaneli ethuluzi namafasitela. Okubaluleke kakhulu, i-polycarbonate isetshenziswa kabanzi emkhakheni wamadivayisi wezokwelapha, njengama-syringes, imishini ye-dialysis kanye namathuluzi okuhlinza, njll. Lezi zinhlelo zokusebenza zibonga ubuthi be-polycarbonate izinto.
4. I-Polycarbonate enobungane nezemvelo
Yize izinto zePolycarbonate ziyinto eqinile futhi eguquguqukayo, iBisphenol A (BPA) ehilelekile ekukhiqizeni kwayo ibibangele impikiswano yezemvelo. Njengoba kuthuthukiswa ubuchwepheshe, kuthuthukiswe imikhiqizo eminingi ye-polycarbonate yemikhiqizo enobungane enciphisa umthelela emvelweni. Ukuphinda usebenzise kabusha kwePolycarbonate futhi kufinyelela kancane kancane, futhi ngenqubo yokuvuselelwa kabusha, izinto ze-polycarbonate zezinto zingaguqulwa zibe yimikhiqizo emisha ukuze ziphinde zinciphise imfucuza yezinsiza.
Ukugcina
Yini i-polycarbonate? Kuyinto impahla ye-polymer enezici ezahlukahlukene eziphakeme, futhi isetshenziswa kabanzi ekwakheni, izinto zokwakha ama-elekthronikhi kanye nezimoto, ezokwelashwa kanye nezinye izinkambu ngenxa yokumelana nomthelela wayo, ukumelana nokushisa kanye nokuqina kwamakhemikhali. Ngokuqwashisa ngokwanda kokuvikelwa kwemvelo, ukuphinda kwenziwe kabusha kwePolycarbonate kukhuthaza kancane kancane. I-Polycarbonate iyinto engokoqobo esebenzayo futhi enamandla entuthuko esimeme.
