Yini impahla ye-PC?
Izinto ze-PC, noma i-polycarbonate, is a polymer impahla edonsele ukunakwa ngezakhiwo zayo ezinhle kakhulu ezibonakalayo nezinhlobonhlobo zezicelo. Kulesi sihloko, sizobhekisisa izakhiwo eziyisisekelo zezinto zokwakha ze-PC, izinhlelo zazo eziphambili nokubaluleka kwazo embonini yamakhemikhali.
Izici eziyisisekelo zezinto zokwenziwa ze-PC
I-Polycarbonate (PC) yaziwa ngamandla ayo amahle nokumelana nomthelela. Uma kuqhathaniswa namanye ama-plastistics amaningi, i-PC inezinga eliphakeme kakhulu lokusobala kanye nezindawo ezinhle zokukhanya, okwenza kube fanele imikhiqizo efana nemishini yokukhanya, iziqukathi ezibonakalayo kanye nokuboniswa. I-PC nayo inokumelana nokushisa okuhle futhi ivame ukukwazi ukuhlala uzinzile ngaphandle kokuwohloka emazingeni okushisa afinyelela ku-120 ° C. Izinto ezibonakalayo zibuye zibe nezakhiwo ezinhle zokufakwa kukagesi. Izinto ezibonakalayo zibuye zibe nezakhiwo ezinhle zokufakwa kukagesi, yingakho zisetshenziswa kabanzi embonini kagesi nakwe-elekthronikhi.
Izindawo zesicelo sezinto zokwakha ze-PC
Ngenxa yezakhiwo zayo ezinhle kakhulu zenyama nangamakhemikhali, i-PC isetshenziswa ezinhlobonhlobo zezicelo. Kwi-elekthronikhi yabathengi, i-PC isetshenziselwa ukwenza izindlu zefoni ephathekayo, amacala we-laptop, njll., Ngoba yibo bobabili abangasindi futhi beqinile. Ezakhiweni nasezimbonini zezimoto, i-PC isetshenziselwa ukwenza amalambu, ama-windscreens, ama-deprarecies wokwakha, nezinye izingxenye ngenxa yamandla aphezulu kanye nokuvikelwa kwamandla e-UV kanye nokupakishwa kokudla, lapho kuthengiswa khona I-BioCOMPITHATI IMbathako futhi ukuqina kwenza kube yinto ehlangabezana nezidingo zokuphepha eziqinile.
Ukwakheka kwamakhemikhali nokucutshungulwa kwezinto ze-PC
Ngokwekhemikhali, okokusebenza kwe-PC kudalulwa ngokusabela kwe-polycondenation phakathi kwe-bisphenol a ne-carbonate. Ukwakheka kwe-molecar chain sakhiwo yaleli polymer kunikeza kwatholakala izakhiwo ezinhle kakhulu zemishini kanye nokuqina okushisayo. Ngokuya nge-Procuting Technology, izinto ze-PC zingabunjwa ngezindlela ezahlukahlukene ezinjengokubumba kokujoyina, ukukhishwa nokushaya ngamandla. Lezi zinqubo zivumela izinto ze-PC ukuthi zivumelaniswe nezidingo zokwakheka kwemikhiqizo ehlukene, ngenkathi kuqinisekisa ukuthi izakhiwo ezibonakalayo zezinto ezibonakalayo azilimalanga.
Imvelo nokusimama kwezinto ze-PC
Naphezu kwezinzuzo eziningi zezinto zokwenziwa kwe-PC, ukukhathazeka kwemvelo kukhulisiwe. Izinto ze-PC yendabuko zivame ukwenziwa ngezinto zokwenziwa ze-petrochemical eziluhlaza, ezenza ukuqina kube yinselele. Eminyakeni yamuva, imboni yamakhemikhali ibikhulisa ngenkuthalo nge-polycarbonases esekelwe kwi-boycarbonases ukunciphisa umthelela wayo wezemvelo. Lokhu okusha kwe-PC akukunciphisi ukukhipha ama-carbon kuphela, kepha futhi kuthuthukisa ukubuyiselwa kabusha kokuqukethwe ngenkathi kugcinwa yizakhiwo zayo zangempela ezibonakalayo.
Ukubeka kafushane
Yini impahla ye-PC? Ngamafuphi, izinto ze-PC ziyi-polycarbonate polymer izinto ezihlala isikhundla esibalulekile ezimbonini ezimbalwa ngenxa yezakhiwo zayo ezinhle kakhulu zemvelo kanye nobubanzi bezinto ezinamathemba ahlukahlukene. Noma ngabe kwi-elekthronikhi yabathengi, ukwakhiwa, imboni yezimoto noma amadivaysi ezokwelapha, ukusetshenziswa kwezinto ze-PC kubonise inani layo elingenakufinyeleleka. Ngokwanda kokuqwashisa ngemvelo kanye nentuthuko yezobuchwepheshe, izinto ze-PC nazo zihamba ngendlela eqhubekayo futhi zinomusa futhi zizoqhubeka nokudlala indima ebalulekile embonini yamakhemikhali ngokuzayo.
