Connecticut (/ kəˈnɛtɪkət/ (Za mawu awa mverani)) ndi dera lakumwera kwenikweni kuchigawo cha New England kumpoto chakum'mawa kwa United States.Pofika pa Census ya 2010, Connecticut ili ndi ndalama zambiri pamunthu aliyense, Human Development Index (0.962), komanso ndalama zapakatikati zapakhomo ku United States.Connecticut ili m'malire ndi Rhode Island kummawa, Massachusetts kumpoto, New York kumadzulo, ndi Long Island Sound kumwera.Likulu lake ndi Hartford ndipo mzinda wokhala ndi anthu ambiri ndi Bridgeport.Ngakhale kuti Connecticut ndi gawo la New England mwaukadaulo, nthawi zambiri imayikidwa pamodzi ndi New York ndi New Jersey ngati dera la Tri-state.Dzikoli limatchedwa Mtsinje wa Connecticut, mtsinje waukulu waku US womwe pafupifupi umadutsa derali.Liwu loti "Connecticut" limachokera ku kalembedwe kosiyanasiyana kwa liwu la Algonquian lotanthauza "mtsinje wautali".
PTFE ndi chiyani?
Polytetrafluoroethylene (PTFE) ndi chinthu chopangidwa mwangozi chakumapeto kwa zaka za m'ma 1930 pomwe katswiri wa zamankhwala akuyesera kupanga mtundu watsopano wa refrigerant wa perfluorethylene.M'malo mokwaniritsa chlorofluorocarbon, wasayansiyo adadabwa kupeza kuti perfluorethylene yomwe idagwiritsidwa ntchito pochita izi idachita ndi chitsulo chomwe chili m'chidebe chake ndikupangidwa ndi polymer mopanikizika.Pasanathe zaka khumi, zinthu zatsopanozi zinali kugawidwa pamalonda ndipo pamapeto pake zidapatsidwa chilolezo chotchedwa polymer®.Zingatenge zaka zina 20 izi zisanachitike poto yokazinga ndikudziwikiratu ngati zokutira zopanda ndodo zophikira, komabe.M'malo mwake, zinthuzi zidagwiritsidwa ntchito pazinthu zosiyanasiyana poyamba.
Panthawi ya Nkhondo Yachiwiri Yapadziko Lonse, PTFE idagwiritsidwa ntchito kuletsa kuthawa kwa zida zotulutsa ma radio pamalo opangira bomba loyamba la atomiki ku US, cholinga chomwe chimatchedwa Manhattan Project.Malowa adayimira malo owoneka bwino okhala ndi masikweya mita 2,000,000 (609,600 sq. metres) momwe mungakhalire uranium hexafluoride.Sikuti chinthuchi chimakhala chapoizoni kwambiri komanso chowononga chokha, komanso chimapanga mpweya wowopsa womwe umadziwika kuti hydrogen fluoride pamaso pa madzi kapena nthunzi yamadzi.Pazifukwa izi, PTFE idagwiritsidwa ntchito ngati zokutira zapaipi kuti ziwapangitse kutayikira umboni.
Zapadera zoteteza zinthu zamtunduwu zidapangitsa kuti kugwiritsidwa ntchito kwake muzinthu zamagetsi kukhala koyenera.Chifukwa chimodzi, si conductive, zomwe zimapangitsa kuti zisagwirizane ndi malo okwera magetsi.Komanso imalimbana kwambiri ndi madzi, kutentha, ndi dzimbiri.M'malo mwake, ikupitilizabe kugwiritsidwa ntchito kupanga zida za labotale ndi zowonjezera zomwe zimakumana ndi hydrofluoric acid, zomwe zingasungunule zida zina, ngakhale magalasi.
PTFE imakhalanso ndi katundu wochepa kwambiri, womwe umawonetsedwa ngati frictional coefficient.Muyezo uwu ndi wocheperako ndipo umasiyana malinga ndi zida zomwe zimalumikizidwa kuti zipangitse kapena kuyerekezera mikangano.Pankhani ya mapulasitiki, kukangana kumawonedwa motsutsana ndi chitsulo chopukutidwa.Kuti PTFE ikhale yocheperako, ndi chinthu chokhacho chodziwika bwino chapamwamba chomwe zala za nalimata zimalephera kumamatira.Khalidweli limapangitsa kuti likhale loyenera kupanga zida zomwe zimafunikira kukana kukangana, monga magiya ndi mayendedwe a mpira.Zambiri
