Yiziphi izinhlelo zokusebenza ze-polycarbonate (PC)?
Kunzima ukucabanga ukuthi izinto eziningi empilweni empeleni zenziwe nge-polycarbonate.
Iyini i-polycarbonate? Kalula nje, i-polycarbonate iyipulasitiki yobunjiniyela ehlanganisa izakhiwo eziningi ezinhle kakhulu. Ngeminyaka engaphezu kwengu-60 yomlando wokuthuthuka, isetshenziswe kabanzi emikhakheni eyahlukene yokuphila kwansuku zonke, futhi abantu abaningi ngokwengeziwe bahlangabezana nokunethezeka nokunethezeka okulethwa yizinto ze-PC. Ipulasitiki yobunjiniyela be-thermoplastic esebenza kahle kakhulu ehlanganisa izici eziningi ezinhle njengokusobala, ukuqina, ukumelana nokuqhekeka, ukumelana nokushisa, kanye nokuncipha komlilo. Ingenye yamapulasitiki amakhulu amahlanu wobunjiniyela. Ngenxa yesakhiwo esiyingqayizivele se-polycarbonate, isiphenduke ipulasitiki yobunjiniyela benhloso evamile ekhula ngokushesha phakathi kwamapulasitiki amakhulu amahlanu wobunjiniyela. Njengamanje, amandla okukhiqiza emhlabeni wonke adlula amathani ayizigidi ezi-5.
Izinto ze-PC zisetshenziswa kabanzi futhi zingacutshungulwa ngokubunjwa komjovo, i-extrusion, nezinye izinqubo. Kunemikhiqizo ehlukahlukene enezinhlelo zokusebenza ezahlukene. Ake sibheke kabanzi izinhlelo zokusebenza eziyi-8 ezijwayelekile zezinto ze-PC ezitholakalayo njengamanje:
1 、 Izingxenye Zezimoto
Izinto ze-PC zinezinzuzo zokubeka izinto obala, ukumelana nomthelela omuhle, nokuzinza okuhle kwe-dimensional, futhi zisetshenziswa kabanzi embonini yezimoto. Isibonelo, ama-sunroofs emoto, izibani zangaphambili, njll. Ngokuthuthuka okusheshayo kwemboni yezimoto, ingxenye yezinto ze-PC ezisetshenziswa embonini yezimoto izokhula kancane kancane. Umklamo uyavumelana nezimo futhi kulula ukuwucubungula, ukuxazulula ubunzima bezobuchwepheshe bezibani zangaphambili zokukhiqiza ingilazi. Njengamanje, izinga lokusetshenziswa kwe-polycarbonate kulo mkhakha e-China cishe li-10%. Imboni ye-elekthronikhi nekagesi, kanye nemboni yokukhiqiza izimoto, iyizimboni eziyinsika zentuthuko esheshayo yaseChina. Ngokuzayo, isidingo se-polycarbonate kule mikhakha sizoba sikhulu.
2 、 Izinto zokwakha
Amashidi aqinile e-PC asetshenziswe ngokuqhubekayo ezakhiweni ezinkulu eminyakeni yamuva nje, njengePantanal Stadium eBrazil kanye ne-Aviva Stadium eDublin, e-Ireland, ngenxa yokuqina kwawo okuhle kakhulu, ukumelana nomthelela, ukwahlukanisa okushisayo, ukubonakala obala, nokumelana nokuguga. Kubikezelwa ukuthi esikhathini esizayo, kuzoba nezakhiwo ezengeziwe futhi ezengeziwe ezisebenzisa le nto ye-PC njengophahla, futhi ingxenye yezakhiwo izokhula. Ngaphezu kwalokho, eminyakeni yamuva nje, amashidi aqinile e-PC asetshenziswe kabanzi ngezindlela ezihlukahlukene zophahla lwemini lwendawo enkulu, izitebhisi zokugada, kanye nezakhiwo eziphakeme zokukhanyisa emini. Kusukela ezindaweni zomphakathi ezifana nezinkundla zebhola kanye namahholo okulinda kuya ezindlini ezizimele kanye nezindawo zokuhlala, uphahla lwe-PC ophahleni lweshidi alinikezi nje abantu umuzwa okhululekile futhi omuhle, kodwa futhi longa amandla.
3 、 Izinto zikagesi
Izinto ze-PC zinokumelana nomthelela omuhle, ukuvala ugesi, nezici zokudaya kalula, futhi zivame ukusetshenziswa emkhakheni wezinto zikagesi, njengamakhamera omakhalekhukhwini, amakesi aphathekayo, amakesi kagesi, namashaja angenantambo. Kulindeleke ukuthi ingxenye yezicelo kule ndawo ingaguquguquki kakhulu esikhathini esizayo.
4 、 Izinto zokwelapha
Ngenxa yekhono layo lokumelana nomusi, ama-ejenti okuhlanza, ukushisisa, kanye nokubulala amagciwane ngemithamo ephezulu ngaphandle kokuphuzi noma ukuwohloka kokusebenza komzimba, imikhiqizo ye-polycarbonate isetshenziswa kabanzi emishinini yokwenziwa ye-hemodialysis yezinso, kanye namanye amadivaysi ezokwelapha adinga ukusebenza okusobala nokunembile futhi ukubulala amagciwane okuphindaphindiwe, njengama-injection anengcindezi ephezulu, izifihla-buso zokuhlinzwa, izinto zamazinyo ezilahlwayo, ama-oxygenator egazi, izinto zokuqoqa igazi nezokugcina, igazi abahlukanisi, njll. Kulindeleke ukuthi isibalo sezicelo kule ndawo sikhule ngokuzayo.
5 、 Ukukhanyisa kwe-LED
Ngemuva kokuguqulwa okukhethekile, amandla we-PC wokusabalalisa ukukhanya azothuthukiswa kakhulu, futhi ukusetshenziswa kwawo emkhakheni we-LED kungasindisa ukusetshenziswa kwamandla. Ekuthuthukisweni okuzayo, ukongiwa kwamandla kuzoba yikona okugxilwe kakhulu kuyo, futhi ingxenye yalesi sici kufanele ikhule kancane kancane. I-polycarbonate engasindi, kulula ukuyicubungula, iqine kakhulu, ibambezeleka ilangabi, ukumelana nokushisa nezinye izakhiwo ze-polycarbonate ikwenza kube ukukhetha okuyinhloko kokufaka izinto zengilazi ekukhanyeni kwe-LED.
6 、 Ukuvikelwa kokuphepha
Izibuko ezivikelayo ezenziwe ngezinto ezingezona ze-PC zingaphazamisa umbala obonakalayo womuntu, kubangele ukuthi umuntu ovikelwe abe nobunzima bokuhlukanisa imibala ezimeni ezithile ezikhethekile futhi adinge ukususwa kwezinto zokuzivikela, ezingase zibangele izingozi. Kodwa-ke, izinto ze-PC zinokucaca okuphezulu, ukumelana nomthelela omuhle, futhi aziphuka kalula, okuzenza zifanelekele izinkundla zokuvikela ukuphepha njengezibuko zokushisela namafasitela wezigqoko zomlilo. Kulindeleke ukuthi ingxenye yezicelo kule ndawo ingaguquguquki kakhulu esikhathini esizayo.
7 、 Ukuxhumana kokudla
Izinga lokushisa lokusetshenziswa kwezinto ze-PC lingafinyelela cishe ku-120 ℃, futhi ngeke likhiphe i-bisphenol A phakathi kwebanga lokuthintana kokudla kwansuku zonke, ngakho-ke ingasetshenziswa ngokuzethemba. Okufana ne-tableware ephezulu, amabhakede okukhipha amanzi, namabhodlela ezingane. Kulindeleke ukuthi ingxenye yezicelo kule ndawo ingaguquguquki kakhulu esikhathini esizayo. Kumele kukhulunywe ukuthi amabhodlela ezingane e-polycarbonate ake athandwa emakethe ngenxa yokukhanya kwawo nokungafihli lutho.
8 、 I-DVD ne-VCD
Eminyakeni embalwa edlule, lapho izimboni ze-DVD ne-VCD zanda, izinto ze-PC zazisetshenziswa kakhulu ukwenza ama-optical disc. Ngokuthuthuka kwezikhathi, ukusetshenziswa kwama-optical discs kuye kwaba yivelakancane, futhi ukusetshenziswa kwezinto ze-PC kule ndawo kuzophinde kwehle unyaka nonyaka esikhathini esizayo. Ngokuvela komjovo wokuqala we-PC omelana nomfutho ophezulu, inkambu yesicelo se-PC isibe banzi nakakhulu. I-PC ingasetshenziswa ukwenza igobolondo le-oxygenator yokuhlinzwa kwe-heart bypass. I-PC iphinde isetshenziswe njengethangi lokugcina igazi kanye nezindlu zokuhlunga ngesikhathi sokuhlanzwa kwezinso, futhi ukubonakala kwayo okuphezulu kuqinisekisa ukuhlolwa okusheshayo kokujikeleza kwegazi, okwenza i-dialysis ibe lula futhi isebenze.
Kusukela ngo-April 2009, iRiphabhulikhi yaseNingizimu Afrika ikhiphe i-passport entsha kubahlali abacishe babe yizigidi ezingama-49, eyenziwe ngefilimu ye-polycarbonate ekhiqizwe yi-Bayer MaterialScience. Lesi sinyathelo sihloselwe ukwenza ngcono ukuphepha kweNdebe Yomhlaba ye-FIFA yowezi-2010 ebanjelwe kuleli. Ngaphezu kwalokho, ezinye izinkambu ezintsha ezifana nezinhlelo zokuzikhanyisa ezingaphansi kwamachibi okubhukuda, izinhlelo zokuvuna amandla elanga, izikrini ezinkulu ze-TV ezinencazelo ephezulu, kanye nemicu ebhalwe ngama-chip ezindwangu ezikwazi ukubona izinto zendwangu ayikwazi ukwenza ngaphandle kokuba khona kwezinto ze-PC. Imikhiqizo ye-PC yenza iminikelo ezimbonini ezihlukahlukene, futhi amandla ayo okusebenza azothuthukiswa.
