Tisanamvetsetse momwe tingadziwire ndikusankha zinthu za CuNi44, tiyenera kumvetsetsa zomwe mkuwa-nickel 44 (CuNi44) ndi. Copper-nickel 44 (CuNi44) ndi aloyi mkuwa-nickel. Monga dzina lake likusonyezera, mkuwa ndi chimodzi mwa zigawo zikuluzikulu za alloy. Nickel ndi chimodzi mwa zigawo zikuluzikulu, ndi zili 43.0% - 45.0%. Kuphatikizika kwa nickel kumatha kupititsa patsogolo mphamvu, kukana kwa dzimbiri, kukana komanso mphamvu ya thermoelectric ya alloy. Kuphatikiza apo, zimaphatikizanso koma sizimangokhala 0.5% - 2.0% manganese. Kukhalapo kwa manganese kumathandizira kukulitsa kukana kwa dzimbiri, kukhazikika kwamafuta ndi mphamvu ya aloyi, koma manganese ochulukirapo angayambitse brittleness.
Copper-nickel 44 imakhala ndi kutentha kwapakati pa kukana, ndipo kukana kwake kumakhala kosasunthika pamene kutentha kumasintha, zomwe zimapangitsa kuti zikhale zofunikira pa ntchito zomwe zimafunika kukhazikika. Ikakhudzidwa ndi kupsinjika ndi kusinthika, chifukwa chomwe mkuwa-nickel 44 imatha kukhala yokhazikika ndikuti mphamvu yake ya mphamvu yamagetsi sisintha nthawi ya pulasitiki ndipo makina amanjenje amachepa. Kuphatikiza apo, CuNi44 ili ndi mphamvu yayikulu ya thermoelectric yamkuwa, imakhala ndi ntchito yabwino yowotcherera, ndipo ndiyosavuta kukonza ndi kulumikizana.
Chifukwa cha mphamvu zake zamagetsi ndi makina, CuNi44 nthawi zambiri imagwiritsidwa ntchito popanga zida zosiyanasiyana zamagetsi monga resistors, potentiometers, thermocouples, ndi zina zotero, mwachitsanzo, monga gawo lofunikira pazitsulo zolondola zamagetsi. M'mafakitale, atha kugwiritsidwa ntchito kupanga mabokosi okanira kwambiri ogulitsa mafakitale, ma rheostats ndi zida zina. Chifukwa cha kukana bwino kwa dzimbiri, ndiyoyeneranso kumadera omwe ali ndi zofunikira zokana kuwononga dzimbiri monga makina amankhwala ndi zida za zombo.
Tikagula zinthu, timadziwa bwanji zida za CuNi44? Nawa njira zitatu zozindikiritsira zomwe munganene.
Choyamba, njira yodziwika bwino ndiyo kugwiritsa ntchito zida zowunikira akatswiri.Monga spectrometers, etc., kuyesa zikuchokera zinthu. Onetsetsani kuti zomwe zili mkuwa ndizotsala, zomwe zili ndi nickel ndi 43.0% - 45.0%, chitsulo ndi ≤0.5%, manganese ndi 0.5% - 2.0%, ndi zinthu zina zili mkati mwazomwe zatchulidwa. Makasitomala athu akagula zinthu za tankii, titha kuwapatsa satifiketi yabwino kapena lipoti la mayeso azinthuzo.
Chachiwiri, ingozindikirani ndikuwonetsetsa kudzera mu mawonekedwe a chinthucho.CuNi44 zakuthupi nthawi zambiri zimapereka kuwala kwachitsulo, ndipo mtunduwo ukhoza kukhala pakati pa mkuwa ndi faifi tambala. Yang'anani ngati pamwamba pa zinthuzo ndi yosalala, popanda zolakwika zoonekeratu, makutidwe ndi okosijeni kapena dzimbiri.
Njira yotsiriza ndiyo kuyesa zinthu zakuthupi za mankhwalawa - kuyeza kuchulukana ndi kuuma kwa zinthuzo.KuNi44ali ndi kachulukidwe kake, komwe kungayesedwe ndi zida zoyezera kachulukidwe kaukadaulo ndikuyerekeza ndi mtengo wokhazikika. Itha kuyezanso ndi tester yolimba kuti mumvetsetse ngati kuuma kwake kumakumana ndi kuuma kwamtundu wa copper-nickel 44.
Msika ndi waukulu kwambiri, momwe tingasankhire wogulitsa yemwe amakwaniritsa zosowa zathu zogula?
Panthawi yofunsa, makasitomala ayenera kufotokozera zofunikira zogwiritsira ntchito.Mwachitsanzo: dziwani kagwiritsidwe ntchito ka zinthuzo. Ngati imagwiritsidwa ntchito popanga zida zamagetsi, mphamvu zake zamagetsi, monga kutsika kwa kutentha kwa kutentha ndi ntchito yabwino yowotcherera, ziyenera kuganiziridwa; ngati imagwiritsidwa ntchito pamakina amankhwala kapena zida za sitima, kukana kwake kwa dzimbiri ndikofunikira kwambiri. Kuphatikizidwa ndi kugwiritsira ntchito ma terminal, kutentha, kuthamanga, kuwononga ndi zinthu zina za chilengedwe chogwiritsira ntchito zimaganiziridwa kuti zitsimikizire kuti CuNi44 yomwe timagula ikhoza kugwira ntchito moyenera pansi pazimenezi.
Komanso, pa nthawi yofunsira, mutha kuwunika woperekayo poyang'ana chiphaso cha woperekayo, kuwunika kwamakasitomala, mbiri yamakampani, ndi zina zambiri. Mukhozanso kufunsa mwachindunji wogulitsa kuti apereke chitsimikizo cha zinthu zakuthupi ndi malipoti oyesa kuti muwonetsetse kuti zinthuzo ndi zodalirika.
Kuphatikiza pa mfundo ziwirizi, kuwongolera mtengo kulinso kofunika.Tiyenera kufananiza mitengo ya ogulitsa osiyanasiyana. Zachidziwikire, sitingangogwiritsa ntchito mtengo ngati njira yokhayo yosankha. Ndikofunikiranso kuganizira zinthu monga zakuthupi, magwiridwe antchito komanso ntchito zogulitsa pambuyo pogulitsa. Moyo wautumiki wa zinthuzo umagwirizana mwachindunji ndi mtengo wokonza. Zinthu zamtengo wapatali za CuNi44 zitha kukhala zokwera mtengo zoyambira, koma zitha kupulumutsa ndalama zolipirira ndikusinthanso pakagwiritsidwe ntchito kwanthawi yayitali.
Pomaliza, ndiyenera kunena kuti musanagule zinthu pamlingo waukulu, mutha kufunsa wopereka zitsanzo kuti ayesedwe. Yesani ngati magwiridwe antchito a zinthuzo akukwaniritsa zofunikira, monga mphamvu zamagetsi, kukana dzimbiri, makina amakina, ndi zina zambiri. Kutengera zotsatira za mayeso, dziwani ngati mungasankhemkuwa-nickel 44zakuthupi za ogulitsa.
