Iyini impahla ye-PC?
I-PC material, noma i-Polycarbonate, i-polymer material eye yaheha ukunakwa kwezakhiwo zayo ezinhle kakhulu zomzimba kanye nohlu olubanzi lwezinhlelo zokusebenza. Kulesi sihloko, sizobheka ngokucophelela izakhiwo eziyisisekelo zezinto ze-PC, izinhlelo zabo eziyinhloko kanye nokubaluleka kwazo embonini yamakhemikhali.
Izakhiwo Eziyisisekelo Zezinto Ze-PC
I-Polycarbonate (PC) yaziwa ngamandla ayo amakhulu kanye nokumelana nomthelela. Uma kuqhathaniswa namanye amapulasitiki amaningi, i-PC inezinga eliphezulu kakhulu lokubonisa izinto obala kanye nezakhiwo ezinhle ze-optical, okuyenza ifaneleke emikhiqizweni efana nemishini yokubona, iziqukathi ezisobala nezibonisi. I-pc futhi inokumelana okuhle nokushisa futhi ivamise ukukwazi ukuhlala izinzile ngaphandle kokuguqulwa emazingeni okushisa afinyelela ku-120°C. Impahla ibuye ibe nezindawo ezinhle zokuvala ugesi. Impahla ibuye ibe nezindawo ezinhle zokuvala ugesi, yingakho isetshenziswa kakhulu embonini kagesi neye-elekthronikhi.
Izindawo zokufaka isicelo sezinto ze-PC
Ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba namakhemikhali, i-PC isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza. Ku-electronics yabathengi, i-PC isetshenziselwa ukwenza izindlu zeselula, amakesi aphathekayo, njll., ngoba ilula futhi iqinile. Ezimbonini zokwakha nezezimoto, i-PC isetshenziselwa ukwenza amalambu, amawindscreen, ukukhanya kwezakhiwo, nezinye izingxenye ngenxa yamandla ayo aphezulu kanye nokumelana nemisebe ye-UV nesimo sezulu esibi, futhi inezinhlelo zokusebenza ezibalulekile kumishini yezokwelapha nasekupakishweni kokudla, lapho i-biocompatibility nokuqina kuyenza into ehlangabezana nezidingo eziqinile zokuphepha.
Isakhiwo samakhemikhali nokucutshungulwa kwezinto ze-PC
Ngokwekhemikhali, impahla ye-PC ihlanganiswa ngokusabela kwe-polycondensation phakathi kwe-bisphenol A ne-carbonate. Isakhiwo seketango lamangqamuzana ale polymer siyinikeza izakhiwo ezinhle kakhulu zemishini kanye nokuzinza kokushisa. Ngokuphathelene nobuchwepheshe bokucubungula, izinto ze-PC zingabunjwa ngezindlela ezihlukahlukene ezifana nokubunjwa komjovo, ukukhishwa kanye nokubunjwa kokushaywa. Lezi zinqubo zivumela impahla ye-PC ukuthi ivumelane nezidingo zedizayini zemikhiqizo ehlukene, kuyilapho iqinisekisa ukuthi izici ezibonakalayo zezinto ezibonakalayo azilinyazwa.
Imvelo kanye nokusimama kwezinto ze-PC
Naphezu kwezinzuzo eziningi zezinto ze-PC, ukukhathazeka kwemvelo kuye kwaphakanyiswa. Izinto ze-PC zendabuko zivame ukwenziwa ngezinto ezingavuthiwe ze-petrochemical, okwenza ukusimama kube inselele. Eminyakeni yamuva nje, imboni yamakhemikhali ibilokhu ikhuthele ukuthuthukisa ama-polycarbonates asekelwe ku-bio ukuze kuncishiswe umthelela wabo kwezemvelo. Le nto entsha ye-PC ayinciphisi kuphela ukukhishwa kwekhabhoni, kodwa futhi ithuthukisa ukugaywa kabusha kwezinto ngenkathi igcina izakhiwo zayo zangempela.
Isifinyezo
Iyini impahla ye-PC? Ngamafuphi, izinto ze-PC ziyi-polycarbonate polymer material ethatha isikhundla esibalulekile ezimbonini eziningana ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba kanye nohlu olubanzi lwamathemba okufaka isicelo. Kungakhathaliseki ukuthi kubathengi bama-electronics, ezokwakha, embonini yezimoto noma ezinsizeni zezokwelapha, ukusetshenziswa kwezinto ze-PC kubonise inani lazo elingenakubuyiseleka. Ngokukhula kokuqwashisa kwezemvelo kanye nentuthuko yezobuchwepheshe, izinto ze-PC nazo zihamba ngendlela esimeme futhi enobungani bemvelo futhi zizoqhubeka nokubamba iqhaza elibalulekile embonini yamakhemikhali esikhathini esizayo.
