Connecticut (/ kəˈnɛtɪkət/ (Nezve ruzha urwu teerera)) inzvimbo yekumaodzanyemba mudunhu reNew England kuchamhembe kwakadziva kumabvazuva kweUnited States.Nezve Census ya2010, Connecticut inoratidzira mari yepamusoro-ye-capita, Human Development Index (0.962), uye mari yepakati yemhuri muUnited States.Connecticut yakaganhurwa neRhode Island kumabvazuva, Massachusetts kuchamhembe, New York kumadokero, uye Long Island Sound kumaodzanyemba.Guta rayo guru iHartford uye guta rayo rine vanhu vakawanda iBridgeport.Kunyangwe Connecticut iri tekinoroji chikamu cheNew England, inowanzo kuunganidzwa pamwe neNew York neNew Jersey senzvimbo yeTri-state.Nyika iyi inodaidzwa kunzi Rwizi rweConnecticut, rwizi rukuru rweUS rwunoda kuganhura nyika.Izwi rekuti "Connecticut" rinotorwa kubva kune akasiyana anglicized zviperengo zvezwi reAlgonquian rekuti "rwizi rurefu rwemvura".
Chii chinonzi PTFE?
Polytetrafluoroethylene (PTFE) chinhu chakagadzirwa netsaona mukupera kwema1930 apo kemisitiri aiedza kugadzira mhando nyowani yeperfluorethylene-based refrigerant.Panzvimbo pekuwana chlorofluorocarbon, musayendisiti akashamisika kuona kuti perfluorethylene yakashandiswa mukuita iyi yakabata nesimbi yemukati mumudziyo wayo uye yakaumbwa pasi pekumanikidzwa.Pasati papera makore gumi gare gare, chinhu chitsva ichi chaive chichigoverwa pachiyero chekutengesa uye chakazopedzisira chave nekodzero pasi pezita rekuti polymer®.Zvingave mamwe makore makumi maviri izvi zvisati zvarova pani yekubikira uye inozivikanwa seyekutanga isina-tsvimbo yekuputira yekubika, zvakadaro.Muchokwadi, chinhu ichi chakashandiswa kune zvakasiyana-siyana zvimwe zvinangwa pakutanga.
Munguva yeHondo Yenyika II, PTFE yakashandiswa kudzivirira kupukunyuka kwezvinhu zvine radioactive kubva panzvimbo yakarongerwa kugadzira bhomba reatomu rekutanga muUS, chinangwa chinodaidzwa kuti Manhattan Project.Nzvimbo iyi yaimiririra chimedu chinokatyamadza chezvivakwa chine 2,000,000 square feet (609,600 sq. metres) umo munogona kuisa uranium hexafluoride.Haisi chete chinhu ichi chine muchetura uye chinoparadza pachacho, asi zvakare chinoumba gasi rine njodzi rinozivikanwa sehydrogen fluoride pamberi pemvura kana mhute yemvura.Nechikonzero ichi, PTFE yakashandiswa seyekuputira pombi yepipefittings kuti iite inovuza humbowo.
Iyo yakasarudzika insulating zvimiro zvechinyorwa ichi chakaita kuti kushandiswa kwayo muzvikamu zvemagetsi kuve kwakanaka.Chimwe chinhu, haisi-conductive, ichiita kuti irege kupikisa minda yemagetsi yakakwirira.Iyo zvakare inoshingirira zvakanyanya kumvura, kupisa, uye makemikari ekuora.Muchokwadi, inoramba ichishandiswa kugadzira michina yemurabhoritari uye zvishongedzo zvinosangana nehydrofluoric acid, iyo yaizonyungudutsa zvimwe zvinhu, kunyangwe girazi.
PTFE zvakare ine yakaderera zvakanyanya frictional properties, iyo inoratidzwa sefrictional coefficient.Chiyero ichi chine hukama uye chinosiyana zvichienderana nemidziyo yakaunzwa kuti ibudise kana kutevedzera kupokana.Panyaya yemapurasitiki, kukwesha kunowanzo onekwa pakatarisana nesimbi yakakwenenzverwa.Kuisa iyo yakaderera friction coefficient yePTFE pakuona kwayo, ndiyo chete inozivikanwa yekugadzira pamusoro pezvinhu izvo zvigunwe zvechigunwe zvinotadza kunamira.Hunhu uhwu hunoita kuti ive yakakodzera kugadzira zvikamu zvinoda kuramba kukweshana, senge magiya nemabhora ebhora.More Details
