I-Connecticut (/ kəˈnɛtɪkət/ (Mayelana nalo msindo lalela)) iyisifunda esiseningizimu impela esifundeni saseNew England enyakatho-mpumalanga ye-United States.Kusukela kubalobantu lwango-2010, i-Connecticut ifaka imali engenayo ephezulu kakhulu nge-capita ngayinye, Inkomba Yokuthuthukiswa Kwabantu (0.962), kanye neholo lekhaya elimaphakathi e-United States.I-Connecticut igujwe yiRhode Island empumalanga, iMassachusetts enyakatho, iNew York ngasentshonalanga, kanye neLong Island Sound eningizimu.Inhloko-dolobha yayo yiHartford futhi idolobha layo elinabantu abaningi yiBridgeport.Nakuba i-Connecticut iyingxenye ye-New England ngokobuchwepheshe, ivamise ukuhlanganiswa kanye ne-New York ne-New Jersey njengendawo ye-Tri-state.Isifunda siqanjwe ngomfula i-Connecticut, umfula omkhulu wase-US ocishe uhlukanise kabili isifunda.Igama elithi "Connecticut" lisuselwa ekupeleni okuhlukile kwegama lesi-Algonquian elisho "umfula omude".
Yini i-PTFE?
I-Polytetrafluoroethylene (PTFE) yinto yokwenziwa eyasungulwa ngephutha ngasekupheleni kwawo-1930 ngenkathi usokhemisi ezama ukwakha uhlobo olusha lwesiqandisi esisekelwe ku-perfluorethylene.Kunokuba athole i-chlorofluorocarbon, usosayensi wamangala ukuthola ukuthi i-perfluorethylene esetshenziswe kule nqubo isabela ngokuqukethwe kwensimbi esitsheni sayo futhi yenziwa i-polymer ngaphansi kwengcindezi.Ngaphansi kweshumi leminyaka kamuva, le nto entsha yayisatshalaliswa ngezinga lezentengiso futhi yagcina inelungelo lobunikazi ngaphansi kwegama elithi polymer®.Kungaba eminye iminyaka engu-20 ngaphambi kokuba le nto ishaye epanini lokuthosa futhi yaziwe ngokuthi i-cookware yokuqala engelona induku ye-cookware.Eqinisweni, le nto yayisetshenziselwa ezinye izinjongo ezihlukahlukene ekuqaleni.
Phakathi neMpi Yezwe II, i-PTFE yasetshenziselwa ukuvimbela ukuphunyuka kwezinto ezikhipha imisebe endaweni ekhethelwe ukukhiqiza ibhomu le-athomu lokuqala e-US, inhloso ebizwa ngokuthi i-Manhattan Project.Le ndawo imele ucezu olumangalisayo lwezindlu ezithengiswayo ezinamafidi-skwele angu-2,000,000 (609,600 sq. metres) lapho okungafakwa khona i-uranium hexafluoride.Akukhona nje kuphela ukuthi le nto inobuthi obuphezulu futhi iyagqwala ngokwayo, kodwa futhi yakha igesi eyingozi eyaziwa ngokuthi i-hydrogen fluoride lapho kukhona amanzi noma umhwamuko wamanzi.Ngenxa yalesi sizathu, i-PTFE yasetshenziswa njengesimbozo sokufakela amapayipi ukuze kube nobufakazi bokuvuza.
Izakhiwo ezihlukile zokuvikela lezi zinto zenze ukusetshenziswa kwayo ezingxenyeni ze-elekthronikhi kwaba kuhle.Phakathi kokunye, ayi-conductive, okwenza imelane nezinkundla zikagesi eziphakeme.Iphinde imelane kakhulu namanzi, ukushisa, nokugqwala kwamakhemikhali.Eqinisweni, iyaqhubeka nokusetshenziswa ukukhiqiza imishini yaselabhorethri kanye nezinsiza ezihlangana ne-hydrofluoric acid, ebingancibilikisa ezinye izinto, ngisho nengilazi.
I-PTFE futhi inezinto eziphansi kakhulu zokungqubuzana, ezivezwa njenge-coefficient ekhukhulayo.Lesi silinganiso sihlobene futhi siyahluka ngokuya ngezinto ezixhunywe ukuze kukhiqizwe noma kulingise ukungqubuzana.Mayelana namapulasitiki, ukungqubuzana kuvame ukubonwa ngokumelene nensimbi epholishiwe.Ukubeka i-coefficient ephansi yokungqubuzana kwe-PTFE endaweni efanele, iyona kuphela impahla engaphezulu yokwenziwa eyaziwa lapho amaphedi ozwane wesigcilikisha ahlulekayo ukunamathela khona.Le khwalithi iyenza ifaneleke ukukhiqiza izingxenye ezidinga ukumelana nokungqubuzana, njengamagiya nama-ball bearings.Imininingwane eyengeziwe
