Manganin ndi aloyi wa manganese ndi mkuwa womwe nthawi zambiri umakhala ndi manganese 12% mpaka 15% ndi nickel yochepa. Mkuwa wa Manganese ndi aloyi wapadera komanso wogwiritsidwa ntchito mosiyanasiyana womwe umadziwika m'mafakitale osiyanasiyana chifukwa cha makhalidwe ake abwino komanso ntchito zake zosiyanasiyana. M'nkhaniyi, tikambirana za kapangidwe kake, makhalidwe ake, ndi njira zambiri zomwe amagwiritsidwira ntchito muukadaulo wamakono.

Kapangidwe ndi katundu wa mkuwa wa manganese

Mkuwa wa Manganesendi aloyi ya mkuwa-nickel-manganese yodziwika bwino chifukwa cha kukana kwake kutentha kochepa (TCR) komanso kukana kwamphamvu kwamagetsi. Kapangidwe kabwino ka mkuwa wa manganese ndi pafupifupi 86% ya mkuwa, 12% ya manganese ndi 2% ya nickel. Kuphatikiza kolondola kumeneku kwa zinthu kumapangitsa kuti zinthuzo zikhale zolimba komanso zotsutsana ndi kusintha kwa kutentha.

Chimodzi mwa zinthu zodziwika bwino za mkuwa wa manganese ndi TCR yake yochepa, zomwe zikutanthauza kuti kukana kwake kumasintha pang'ono kwambiri ndi kusinthasintha kwa kutentha. Kapangidwe kameneka kamapangitsa mkuwa-manganese kukhala chinthu choyenera kugwiritsa ntchito poyesa magetsi molondola komanso mokhazikika, monga zotsutsana ndi magauge okhwima. Kuphatikiza apo, mkuwa wa manganese uli ndi mphamvu zamagetsi zambiri, zomwe zimapangitsa kuti ugwiritsidwe ntchito pazida zosiyanasiyana zamagetsi ndi zamagetsi.

Kugwiritsa ntchito mkuwa wa manganese

Kapangidwe kake ka mkuwa wa manganese kamapangitsa kuti ukhale chinthu chamtengo wapatali chomwe chimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Chimodzi mwa zinthu zazikulu zomwe zimagwiritsidwa ntchito popanga mkuwa wa manganese ndi kupanga ma resistors olondola. Chifukwa cha TCR yochepa komanso kukana kwakukulu, ma resistors a manganese-copper amagwiritsidwa ntchito kwambiri m'mabwalo amagetsi, zida zamagetsi ndi zida zoyezera komwe kulondola ndi kukhazikika ndikofunikira kwambiri.

Ntchito ina yofunika kwambiri ya mkuwa wa manganese ndi kupanga ma strain gauges. Zipangizozi zimagwiritsidwa ntchito poyesa kupsinjika kwa makina ndi masinthidwe a kapangidwe ndi zinthu. Mkuwa wa manganese uli ndi mphamvu yokhazikika komanso mphamvu yayikulu, zomwe zimapangitsa kuti ukhale chisankho chabwino kwambiri cha ma strain gauge sensors m'ma cell olemera, ma pressure sensors, ndi ma industrial monitoring system applications.

Kuphatikiza apo, mkuwa ndi manganese zimagwiritsidwa ntchito popanga ma shunt, chipangizo chomwe chimayesa mphamvu yamagetsi podutsa gawo lodziwika la mphamvu yamagetsi kudzera mu resistor yolinganizidwa. TCR yotsika komanso mphamvu yayikulu ya mkuwa wa manganese zimapangitsa kuti ikhale chinthu choyenera kwambiri pa ma shunt yamagetsi, zomwe zimapangitsa kuti mphamvu yamagetsi iyesedwe molondola komanso modalirika m'makina osiyanasiyana amagetsi.

Kuwonjezera pa kugwiritsa ntchito magetsi,mkuwa wa manganeseimagwiritsidwa ntchito popanga zida zolondola, monga ma thermometer, ma thermocouple, ndi masensa oyesera kutentha. Kukhazikika kwake komanso kukana dzimbiri kumapangitsa kuti ikhale chinthu chofunikira kwambiri pazida zomwe zimafuna kuyeza kutentha molondola m'malo osiyanasiyana.

Tsogolo la mkuwa wa manganese

Pamene ukadaulo ukupita patsogolo, kufunikira kwa zipangizo zokhala ndi mphamvu zamagetsi ndi makina abwino kwambiri kukupitirirabe kukula. Chifukwa cha kuphatikiza kwake kwapadera kwa mphamvu, manganese-mkuwa akuyembekezeka kukhala ndi gawo lofunikira pakupanga zida zamagetsi ndi zida zowunikira za m'badwo wotsatira. Kukhazikika kwake, kudalirika kwake komanso kusinthasintha kwake kumapangitsa kuti ikhale chinthu chofunikira kwambiri m'mafakitale monga ndege, magalimoto, mauthenga ndi chisamaliro chaumoyo.

Mwachidule, manganese-mkuwa ndi chinthu chapadera chomwe chakhala chinthu chofunikira kwambiri pakupanga zinthu molondola komanso kugwiritsa ntchito zida zamagetsi. Kapangidwe kake, makhalidwe ake, ndi ntchito zake zosiyanasiyana zimapangitsa kuti chikhale chinthu chamtengo wapatali pakupanga ukadaulo wapamwamba komanso kufunafuna kulondola kwambiri komanso kugwira ntchito bwino m'magawo osiyanasiyana. Pamene tikupitilizabe kupititsa patsogolo luso latsopano, manganese mkuwa mosakayikira upitiliza kukhala gawo lofunikira pakukonza tsogolo la ukadaulo wamakono.
