Zeziphi izicelo zepolycarbonate (PC)?
Kunzima ukucinga ukuba izinto ezininzi ebomini zenziwe nge-polycarbonate.
Yintoni i-polycarbonate? Ukubeka ngokulula, i-polycarbonate yiplastiki yobunjineli edibanisa iipropathi ezininzi ezigqwesileyo. Ngaphezulu kweminyaka engama-60 yembali yophuhliso, isetyenziswe ngokubanzi kwiinkalo ezahlukeneyo zobomi bemihla ngemihla, kwaye abantu abaninzi ngakumbi bahlangabezana nokulula kunye nentuthuzelo esiziswa yizinto zePC. Yiplastiki yobunjineli be-thermoplastic esebenza kakhulu edibanisa iimpawu ezininzi ezibalaseleyo ezifana nokungafihli, ukuqina, ukuxhathisa ukwaphuka, ukumelana nobushushu, kunye nokuncitshiswa komlilo. Yenye yeeplastiki ezintlanu zobunjineli ezinkulu. Ngenxa yolwakhiwo olukhethekileyo lwepolycarbonate, iye yaba yeyona ikhula ngokukhawuleza iplastiki yobunjineli yobunjineli phakathi kweeplastiki ezinkulu ezintlanu zobunjineli. Okwangoku, umthamo wemveliso yehlabathi udlula iitoni ezizigidi ezi-5.
Izinto zePC zisetyenziswa kakhulu kwaye zinokulungiswa ngokubumba inaliti, i-extrusion, kunye nezinye iinkqubo. Kukho iimveliso ezahlukeneyo ezinezicelo ezahlukeneyo. Makhe sijonge ngokweenkcukacha usetyenziso olusi-8 lwemathiriyeli yePC ekhoyo ngoku:
1 、 iiNdawo zeemoto
Izixhobo zePC zineengenelo zokungafihli, ukumelana nempembelelo entle, kunye nokuzinza okuhle komgangatho, kwaye zisetyenziswa ngokubanzi kushishino lweemoto. Umzekelo, ii-sunroofs zemoto, izibane zangaphambili, njl. Ngophuhliso olukhawulezayo lweshishini leemoto, ubungakanani bezinto zePC ezisetyenziswa kushishino lweemoto ziya kunyuka ngokuthe ngcembe. Uyilo luguquguqukayo kwaye kulula ukuluqhuba, ukusombulula ubunzima bezobugcisa bezibane zokuvelisa iglasi zemveli. Okwangoku, izinga lokusetyenziswa kwe-polycarbonate kule ndawo e-China limalunga ne-10 kuphela. Ishishini le-elektroniki kunye nombane, kunye neshishini lokwenziwa kweemoto, ngamashishini eentsika zophuhliso olukhawulezayo lwaseTshayina. Kwixesha elizayo, imfuno yepolycarbonate kula mabala iya kuba nkulu.
2 、 Izinto zokwakha
Amaphepha aqinileyo ePC asetyenziswa ngokuqhubekayo kwizakhiwo ezikhulu kwiminyaka yakutshanje, njengePantanal Stadium eBrazil kunye neBala Lemidlalo laseAviva eDublin, eIreland, ngenxa yozinzo lwazo olubalaseleyo, ukuchasana nempembelelo, ukugqunywa kwe-thermal, ukungafihli, kunye nokumelana nokuguga. Kuqikelelwa ukuba kwixesha elizayo, kuya kuba nezakhiwo ezininzi ngakumbi nangakumbi zisebenzisa le mathiriyeli yePC njengophahla, kwaye umyinge wezakhiwo uya kwanda. Ukongeza, kwiminyaka yakutshanje, amaxwebhu aqinileyo ePC asetyenziswe ngokubanzi kwiimilo ezahlukeneyo zophahla lwemini enkulu, izitebhisi zokulinda, kunye nezakhiwo eziphakamileyo zokukhanya emini. Ukusuka kwiindawo zikawonke-wonke ezifana namabala ebhola ekhatywayo kunye neeholo zokulinda ukuya kwiivillas kunye neendawo zokuhlala, uphahla lwe-PC olucacileyo lwe-ceiling sheet alunikezi nje abantu imvakalelo ekhululekile kunye nenhle, kodwa kunye nokugcina amandla.
3 、 Izixhobo zombane
Izinto zePC zinempembelelo entle yokuchasa, ukugqunywa kombane, kunye neempawu zokudaya ngokulula, kwaye ziqhele ukusetyenziswa kwindawo yezixhobo zombane, ezinjengeekhamera zefowuni ephathwayo, iimeko zelaptop, iimeko zesixhobo, kunye neetshaja ezingenazingcingo. Kulindeleke ukuba umlinganiselo wezicelo kulo mmandla ungaguquguquki kakhulu kwixesha elizayo.
4 、 Izinto zonyango
Ngenxa yokukwazi ukumelana nomphunga, iiarhente zokucoca, ukufudumeza, kunye nedosi ephezulu yokubulala iintsholongwane ngaphandle kokutyheli okanye ukonakaliswa kokusebenza komzimba, iimveliso zepolycarbonate zisetyenziswa ngokubanzi kwizixhobo zokwenziwa kwe-hemodialysis yezintso, kunye nezinye izixhobo zonyango ezifuna ukusebenza okuselubala nokucacileyo kunye Ukubulala iintsholongwane ngokuphindaphindiweyo, ezifana ne-high-pressure-injection, iimaski zotyando, izixhobo zamazinyo ezilahlwayo, i-oksijeni yegazi, ukuqokelela igazi kunye nezixhobo zokugcina, igazi. abahluli, njl. Kulindeleke ukuba umlinganiselo wezicelo kule ndawo unyuke kwixesha elizayo.
5 、 Ukukhanya kwe-LED
Emva kokuguqulwa okukhethekileyo, amandla e-PC okusasaza ukukhanya kuya kuphuculwa kakhulu, kwaye ukusetyenziswa kwayo kwintsimi ye-LED kunokugcina ukusetyenziswa kwamandla. Kuphuhliso lwexesha elizayo, ukugcinwa kwamandla kuya kuba yingqwalasela ephambili, kwaye inxalenye yalo mba kufuneka inyuke ngokuthe ngcembe. Ikhaphukhaphu, kulula ukusetyenzwa, ukuqina okuphezulu, ukubuyiswa komlilo, ukumelana nobushushu, kunye nezinye iipropathi zepolycarbonate zenza kube lolona khetho luphambili lokutshintsha izinto zeglasi ekukhanyeni kwe-LED.
6 、 Ukhuseleko lokhuseleko
Izibuko ezikhuselayo ezenziwe ngezinto ezingezizo iPC zinokuphazamisana nombala wokubonwa komntu, nto leyo ebangela ukuba umntu okhuselweyo abe nobunzima bokuhlukanisa imibala kwiimeko ezithile ezikhethekileyo kwaye afune ukususwa kwezixhobo zokukhusela, ezinokukhokelela kwiingozi. Nangona kunjalo, izixhobo zePC zinokucaca okuphezulu, ukuchasana kwempembelelo entle, kwaye aziqhekeki ngokulula, zizenza zilungele amasimi okhuseleko anjengeeglasi zokuwelda kunye neefestile zokhuseleko lomlilo. Kulindeleke ukuba umlinganiselo wezicelo kulo mmandla ungaguquguquki kakhulu kwixesha elizayo.
7 、 Uqhagamshelwano lokutya
Ubushushu bokusetyenziswa kwezinto zePC bunokufikelela malunga ne-120 ℃, kwaye ayiyi kukhulula i-bisphenol A phakathi koqhagamshelwano lokutya kwemihla ngemihla, ngoko inokusetyenziswa ngokuzithemba. Ezinje ngeetafile ezikumgangatho ophezulu, iibhakethi zokuhambisa amanzi, kunye neebhotile zabantwana. Kulindeleke ukuba umlinganiselo wezicelo kulo mmandla ungaguquguquki kakhulu kwixesha elizayo. Kufuneka kukhankanywe ukuba iibhotile ze-polycarbonate zabantwana zazidume kwimarike ngenxa yobunzima kunye nokubonakala kwazo.
8 、 IDVD kunye neVCD
Kwiminyaka embalwa edlulileyo, xa amashishini eDVD kunye neVCD ayexhaphakile, izixhobo zePC zazisetyenziswa kakhulu ukwenza iidiski zamehlo. Ngophuhliso lwamaxesha, ukusetyenziswa kweediski ze-optical kuye kwanda kunqabile, kwaye ukusetyenziswa kwezixhobo zePC kule ndawo kuya kuncipha kwakhona ngonyaka kwixesha elizayo. Ngokuvela kwenaliti yokuqala ye-PC enoxinzelelo oluphezulu, indawo yesicelo sePC iye yanda ngakumbi. I-PC ingasetyenziselwa ukwenza iqokobhe le-oxygenator yotyando lwe-heart bypass. I-PC ikwasetyenziswa njengetanki yokugcina igazi kunye nezindlu zokucoca ngexesha le-dialysis yezintso, kwaye ukucaca kwayo okuphezulu kuqinisekisa ukuhlolwa ngokukhawuleza kokujikeleza kwegazi, ukwenza i-dialysis ilula kwaye isebenze.
Ukusukela ngo-Epreli ka-2009, iRiphabhlikhi yoMzantsi Afrika ikhuphe ipaspoti entsha kubahlali abaphantse babe zizigidi ezingama-49, eyenziwe ngefilimu yepolycarbonate eveliswe yiBayer MaterialScience. Eli nyathelo lijolise ekuphuculeni ukhuseleko lweNdebe yeHlabathi yeFIFA ka-2010 ebanjelwe kweli lizwe. Ukongeza, amanye amasimi amatsha anje ngeenkqubo zokuzikhanyisa ezantsi kwamadama okuqubha, iinkqubo zokuvuna amandla elanga, izikrini ezinkulu zeTV ezinenkcazo ephezulu, kunye neentsinga eziphawulwe nge-chip kwilaphu ezinokubona imathiriyeli yelaphu ayinakwenza ngaphandle kobukho bezinto zePC. Iimveliso zePC zenza igalelo kumashishini ahlukeneyo, kwaye amandla azo okusebenza aya kuphuhliswa ngakumbi.
