Ua ntej nkag siab txog yuav ua li cas txheeb xyuas thiab xaiv cov khoom siv CuNi44, peb yuav tsum nkag siab txog tooj liab-nickel 44 (CuNi44) yog dab tsi. Tooj liab-nickel 44 (CuNi44) yog cov khoom siv tooj liab-nickel alloy. Raws li nws lub npe qhia, tooj liab yog ib qho ntawm cov khoom tseem ceeb ntawm cov hlau. Nickel kuj yog ib qho ntawm cov khoom tseem ceeb, nrog rau cov ntsiab lus ntawm 43.0% - 45.0%. Kev ntxiv ntawm nickel tuaj yeem txhim kho lub zog, kev tiv thaiv corrosion, kev tiv thaiv thiab cov khoom thermoelectric ntawm cov hlau. Tsis tas li ntawd, nws suav nrog tab sis tsis txwv rau 0.5% - 2.0% manganese. Qhov muaj manganese pab txhim kho qhov kev tiv thaiv corrosion, thermal stability thiab lub zog ntawm cov hlau, tab sis ntau dhau manganese yuav ua rau brittleness.
Tooj-nickel 44 muaj qhov kub tsis tshua muaj zog, thiab nws qhov kev tiv taus ruaj khov thaum qhov kub hloov pauv, uas ua rau nws muaj txiaj ntsig zoo rau cov ntawv thov uas xav tau kev ruaj khov. Thaum raug kev ntxhov siab thiab kev hloov pauv, qhov laj thawj vim li cas tooj-nickel 44 tuaj yeem tswj tau qhov kev ua tau zoo ruaj khov yog tias nws cov coefficient rhiab heev tsis hloov pauv thaum lub sijhawm yas thiab qhov hysteresis kho tshuab me me. Tsis tas li ntawd, CuNi44 muaj peev xwm thermoelectric loj rau tooj, muaj kev ua haujlwm vuam zoo, thiab yooj yim rau kev ua thiab kev sib txuas.
Vim nws cov khoom siv hluav taws xob thiab kho tshuab zoo, CuNi44 feem ntau siv los tsim ntau yam khoom siv hluav taws xob xws li resistors, potentiometers, thermocouples, thiab lwm yam, piv txwv li, ua ib qho tseem ceeb hauv cov cuab yeej hluav taws xob precision. Hauv kev lag luam, nws tuaj yeem siv los tsim cov thawv tiv thaiv kev lag luam siab, rheostats thiab lwm yam khoom siv. Vim nws txoj kev tiv thaiv corrosion zoo, nws kuj tsim nyog rau cov chaw uas muaj kev tiv thaiv corrosion siab xws li cov tshuab tshuaj lom neeg thiab cov khoom siv nkoj.
Thaum peb yuav cov khoom, peb yuav txheeb xyuas cov khoom siv CuNi44 li cas? Nov yog peb txoj kev txheeb xyuas rau koj siv.
Ua ntej, txoj hauv kev yooj yim tshaj plaws yog siv cov khoom siv tshuaj lom neeg tshaj lij.Xws li cov spectrometers, thiab lwm yam, los sim cov khoom sib xyaw ua ke. Xyuas kom tseeb tias cov ntsiab lus tooj liab yog cov seem, cov ntsiab lus nickel yog 43.0% - 45.0%, cov ntsiab lus hlau yog ≤0.5%, cov ntsiab lus manganese yog 0.5% - 2.0%, thiab lwm yam ntsiab lus nyob hauv qhov ntau yam teev tseg. Thaum peb cov neeg siv khoom yuav cov khoom tankii, peb tuaj yeem muab rau lawv daim ntawv pov thawj zoo lossis daim ntawv qhia kev xeem ntawm cov khoom siv.
Qhov thib ob, tsuas yog txheeb xyuas thiab tshuaj xyuas cov yam ntxwv ntawm cov khoom.Cov khoom siv CuNi44 feem ntau muaj lub teeb ci ntsa iab, thiab xim yuav nyob nruab nrab ntawm tooj liab thiab nickel. Saib seb qhov chaw ntawm cov khoom siv puas du, tsis muaj qhov tsis zoo, oxidation lossis xeb.
Txoj kev kawg yog sim cov khoom siv lub cev ntawm cov khoom - ntsuas qhov ceev thiab qhov nyuaj ntawm cov khoom.CuNi44muaj qhov ntau thiab tsawg ntawm qhov ceev, uas tuaj yeem kuaj tau los ntawm cov cuab yeej ntsuas qhov ceev tshaj lij thiab piv rau tus nqi txheem. Nws kuj tseem tuaj yeem ntsuas nrog lub cuab yeej ntsuas qhov nyuaj kom nkag siab seb nws qhov nyuaj puas ua tau raws li qhov ntau thiab tsawg ntawm tooj liab-nickel 44.
Lub lag luam loj heev, yuav ua li cas xaiv tus neeg muag khoom uas ua tau raws li peb cov kev xav tau yuav khoom?
Thaum lub sijhawm nug, cov neeg siv khoom yuav tsum piav qhia meej txog cov kev cai siv.Piv txwv li: txiav txim siab seb cov khoom siv tshwj xeeb siv li cas. Yog tias nws siv rau kev tsim cov khoom siv hluav taws xob, nws cov khoom siv hluav taws xob, xws li qhov kub thiab txias tsis kam thiab kev ua haujlwm vuam zoo, yuav tsum tau xav txog; yog tias nws siv rau cov tshuab tshuaj lom neeg lossis cov khoom siv nkoj, nws qhov kev tiv thaiv corrosion tseem ceeb dua. Ua ke nrog kev siv lub davhlau ya nyob twg, qhov kub thiab txias, siab, corrosiveness thiab lwm yam ntawm qhov chaw siv raug coj los xav txog kom ntseeg tau tias CuNi44 peb yuav tuaj yeem ua haujlwm ib txwm nyob rau hauv cov xwm txheej no.
Tsis tas li ntawd xwb, thaum lub sijhawm nug, koj tuaj yeem soj ntsuam tus neeg muag khoom los ntawm kev kuaj xyuas daim ntawv pov thawj kev tsim nyog ntawm tus neeg muag khoom, kev ntsuam xyuas cov neeg siv khoom, lub koob npe nrov hauv kev lag luam, thiab lwm yam. Koj tuaj yeem thov ncaj qha rau tus neeg muag khoom kom muab cov ntaub ntawv pov thawj zoo thiab cov ntawv xeem kom ntseeg tau tias qhov zoo ntawm cov khoom siv ntseeg tau.
Ntxiv rau ob lub ntsiab lus saum toj no, kev tswj tus nqi kuj tseem ceeb heev.Peb yuav tsum sib piv cov nqi ntawm cov neeg muag khoom sib txawv. Tau kawg, peb tsis tuaj yeem siv tus nqi ua tus qauv xaiv xwb. Nws tseem ceeb heev uas yuav tsum xav txog cov yam xws li cov khoom zoo, kev ua tau zoo thiab kev pabcuam tom qab muag. Lub neej ua haujlwm ntawm cov khoom siv muaj feem cuam tshuam ncaj qha rau tus nqi txij nkawm. Cov khoom siv CuNi44 zoo yuav muaj tus nqi pib siab dua, tab sis nws yuav txuag tau tus nqi txij nkawm thiab hloov pauv hauv kev siv mus sij hawm ntev.
Thaum kawg, nws tsim nyog hais tias ua ntej yuav cov khoom loj, koj tuaj yeem nug tus neeg muag khoom kom muab cov qauv rau kev sim. Sim seb qhov kev ua tau zoo ntawm cov khoom siv puas ua tau raws li qhov yuav tsum tau ua, xws li cov khoom siv hluav taws xob, kev tiv thaiv corrosion, cov khoom siv kho tshuab, thiab lwm yam. Raws li cov txiaj ntsig ntawm kev sim, txiav txim siab seb puas yuav xaiv qhovtooj liab-nickel 44cov khoom siv ntawm tus neeg muab khoom.
