Tisanamvetse momwe tingadziwire ndikusankha zinthu za CuNi44, tiyenera kumvetsetsa kuti copper-nickel 44 (CuNi44) ndi chiyani. Nikeli ya mkuwa 44 (CuNi44) ndi chinthu chopangidwa ndi mkuwa ndi nickel alloy. Monga momwe dzina lake likusonyezera, mkuwa ndi chimodzi mwa zigawo zazikulu za alloy. Nickel ndi chimodzi mwa zigawo zazikulu, chokhala ndi 43.0% - 45.0%. Kuwonjezera nickel kungathandize kulimbitsa mphamvu, kukana dzimbiri, kukana komanso mphamvu zamagetsi za alloy. Kuphatikiza apo, imaphatikizapo koma sikungolekezera pa 0.5% - 2.0% manganese. Kupezeka kwa manganese kumathandiza kulimbitsa kukana dzimbiri, kukhazikika kwa kutentha ndi mphamvu ya alloy, koma manganese wochuluka angayambitse kusweka.
Copper-nickel 44 ili ndi mphamvu yotsika kutentha, ndipo mphamvu yake imakhala yokhazikika kutentha kukasintha, zomwe zimapangitsa kuti ikhale yothandiza pa ntchito zomwe zimafunika kuti mphamvu yolimba ikhazikike. Ikakumana ndi kupsinjika ndi kusintha kwa zinthu, chifukwa chomwe copper-nickel 44 imatha kukhalabe ndi mphamvu yokhazikika ndikuti mphamvu yake yolimba simasintha nthawi ya kupsinjika kwa pulasitiki ndipo mphamvu ya makina ndi yochepa. Kuphatikiza apo, CuNi44 ili ndi mphamvu yayikulu ya thermoelectric yolimbana ndi mkuwa, ili ndi mphamvu yabwino yolumikizira, ndipo ndi yosavuta kuikonza ndi kuilumikiza.
Chifukwa cha mphamvu zake zamagetsi ndi makina abwino, CuNi44 nthawi zambiri imagwiritsidwa ntchito popanga zida zosiyanasiyana zamagetsi monga zotsutsana, ma potentiometer, ma thermocouple, ndi zina zotero, mwachitsanzo, ngati gawo lofunikira pazida zamagetsi zolondola. M'mafakitale, ingagwiritsidwe ntchito popanga mabokosi olimbana ndi mafakitale ambiri, ma rheostat ndi zida zina. Chifukwa cha kukana kwake dzimbiri, ndi yoyeneranso malo omwe ali ndi zofunikira kwambiri pakukana dzimbiri monga makina a mankhwala ndi zida zoyendera.
Tikagula zinthu, kodi timazindikira bwanji zinthu za CuNi44? Nazi njira zitatu zodziwira zomwe mungagwiritse ntchito.
Choyamba, njira yosavuta kwambiri ndiyo kugwiritsa ntchito zida zaukadaulo zowunikira mankhwala.Monga ma spectrometer, ndi zina zotero, kuti muyese kapangidwe ka zinthuzo. Onetsetsani kuti mkuwa ndi wotsala, nickel ndi 43.0% - 45.0%, chitsulo ndi ≤0.5%, manganese ndi 0.5% - 2.0%, ndipo zinthu zina zili mkati mwa mulingo womwe watchulidwa. Makasitomala athu akagula zinthu za tankii, tikhoza kuwapatsa satifiketi yaubwino kapena lipoti loyesa la zinthuzo.
Chachiwiri, ingodziwani ndikuwunika mawonekedwe a chinthucho.Zinthu za CuNi44 nthawi zambiri zimakhala ndi kuwala kwachitsulo, ndipo mtundu wake ukhoza kukhala pakati pa mkuwa ndi nikeli. Yang'anani ngati pamwamba pa zinthuzo pali posalala, popanda zolakwika zoonekeratu, kukhuthala kapena dzimbiri.
Njira yomaliza ndiyo kuyesa mawonekedwe enieni a chinthucho - kuyeza kuchuluka ndi kuuma kwa chinthucho.CuNi44Ili ndi kuchuluka kwa kachulukidwe, komwe kungayesedwe ndi zida zoyezera kachulukidwe ka akatswiri ndikuyerekezeredwa ndi mtengo wamba. Ikhozanso kuyezedwa ndi choyesera kuuma kuti mumvetse ngati kuuma kwake kukukwaniritsa kuchuluka kwa kuuma kwa mkuwa-nickel 44.
Msika ndi waukulu kwambiri, kodi mungasankhe bwanji wogulitsa amene akwaniritsa zosowa zathu zogulira?
Mu nthawi yofunsa mafunso, makasitomala ayenera kufotokoza bwino zomwe zimafunika kuti agwiritse ntchito.Mwachitsanzo: dziwani momwe zinthuzo zimagwiritsidwira ntchito. Ngati zikugwiritsidwa ntchito popanga zinthu zamagetsi, ziyenera kuganiziridwa kuti mphamvu zake zamagetsi, monga kutentha kochepa komanso kugwira ntchito bwino kwa welding, ziyenera kuganiziridwa; ngati zikugwiritsidwa ntchito pamakina a mankhwala kapena zida zoyendera, kukana kwake dzimbiri ndikofunikira kwambiri. Kuphatikiza ndi kugwiritsa ntchito kwa terminal, kutentha, kuthamanga, kuwononga ndi zinthu zina zomwe zimagwiritsidwa ntchito zimaganiziridwa kuti zitsimikizire kuti CuNi44 yomwe timagula imatha kugwira ntchito bwino pansi pa mikhalidwe iyi.
Kuphatikiza apo, panthawi yofufuza, mutha kuwunika wogulitsa poyang'ana satifiketi yoyenerera ya wogulitsa, kuwunika kwa makasitomala, mbiri yamakampani, ndi zina zotero. Muthanso kupempha mwachindunji wogulitsayo kuti apereke chitsimikizo cha khalidwe la zinthuzo ndi malipoti oyesera kuti atsimikizire kuti mtundu wa zinthuzo ndi wodalirika.
Kuwonjezera pa mfundo ziwiri zomwe zili pamwambapa, kuwongolera ndalama ndikofunikiranso.Tifunika kuyerekeza mitengo ya ogulitsa osiyanasiyana. Zachidziwikire, sitingagwiritse ntchito mtengo ngati njira yokhayo yosankhira. Ndikofunikiranso kuganizira zinthu monga mtundu wa zinthu, magwiridwe antchito, ndi ntchito yogulitsa pambuyo pogulitsa. Moyo wa ntchito ya zinthuzo umagwirizana mwachindunji ndi mtengo wokonzera. Zinthu za CuNi44 zapamwamba kwambiri zitha kukhala ndi mtengo woyambira wokwera, koma zitha kusunga ndalama zokonzera ndi zosinthira zikagwiritsidwa ntchito kwa nthawi yayitali.
Pomaliza, ndikofunikira kunena kuti musanagule zinthu zambiri, mutha kufunsa wogulitsayo kuti akupatseni zitsanzo kuti muyesedwe. Yesani ngati magwiridwe antchito a zinthuzo akukwaniritsa zofunikira, monga mphamvu zamagetsi, kukana dzimbiri, mphamvu zamakanika, ndi zina zotero. Kutengera zotsatira za mayeso, sankhani ngati mungasankhenikeli wa mkuwa 44zinthu za wogulitsa.
