Alnico yog dab tsi?
Alnico yog ib hom hlau nplaum ruaj khov uas yog ua los ntawm txhuas, npib tsib xee, thiab cobalt. Nws yog thawj zaug tsim nyob rau hauv 1930s thiab paub txog nws cov khoom muaj zog sib nqus thiab siab tiv thaiv demagnetization. Alnico yog siv nyob rau hauv ntau yam khoom, xws li hluav taws xob motors, guitar pickups, thiab sensors.
Qhov zoo ntawm Alnico
1. Muaj zog sib nqus
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm alnico yog nws lub zog sib nqus siab. Alnico hlau nplaum yog lub npe hu rau muaj qee qhov muaj zog sib nqus ntawm cov hlau nplaum ruaj khov. Qhov no ua rau lawv muaj txiaj ntsig zoo hauv ntau daim ntawv thov uas yuav tsum muaj cov hlau nplaum muaj zog, xws li hauv cov tshuab hluav taws xob thiab cov tshuab hluav taws xob.
2. Kev ua haujlwm siab rau demagnetization
Lwm qhov zoo ntawm alnico yog nws qhov kev tiv thaiv siab rau demagnetization. Tsis zoo li ntau lwm hom hlau nplaum, alnico hlau nplaum tsis yooj yim demagnetized los ntawm sab nraud magnetic teb. Qhov no txhais tau hais tias lawv tuaj yeem tuav lawv lub zog sib nqus txawm nyob hauv ib puag ncig uas lawv raug rau cov hlau nplaum muaj zog.
3. Zoo kub stability
Alnico hlau nplaum muaj qhov kub thiab txias, uas txhais tau hais tias lawv tuaj yeem tuav lawv lub zog sib nqus txawm nyob rau qhov kub thiab txias. Qhov no ua rau lawv muaj txiaj ntsig zoo hauv qhov chaw kub kub, xws li hauv cov tshuab dav hlau thiab cov tsheb ua haujlwm siab.
4. Zoo corrosion kuj
Alnico hlau nplaum kuj paub txog lawv cov corrosion kuj zoo. Lawv tiv taus xeb thiab lwm yam kev xeb, uas ua rau lawv muaj txiaj ntsig zoo nyob rau hauv qhov chaw sab nraum zoov lossis dej hiav txwv uas lawv tuaj yeem raug ya raws thiab dej ntsev.
Disadvantages ntawm Alnico
1. Tus nqi siab
Ib qho ntawm qhov tsis zoo ntawm alnico yog nws cov nqi siab. Alnico hlau nplaum yog kim dua los tsim dua li ntau lwm hom hlau nplaum, uas ua rau lawv tsis tshua muaj nqi rau qee qhov kev siv.
2. Brittle thiab nyuaj rau tshuab
Alnico hlau nplaum kuj nkig thiab nyuaj rau tshuab, uas tuaj yeem ua rau lawv nyuaj rau kev ua haujlwm nrog. Lawv xav tau cov cuab yeej tshwj xeeb thiab cov tswv yim los tsim thiab ua tiav, uas tuaj yeem ntxiv rau tag nrho cov nqi ntawm kev siv cov hlau nplaum alnico.
3. Txwv cov duab sib nqus thiab qhov ntau thiab tsawg
Lwm qhov tsis zoo ntawm alnico hlau nplaum yog lawv qhov txwv ntawm cov duab sib nqus thiab qhov ntau thiab tsawg. Alnico hlau nplaum feem ntau muaj nyob rau hauv ob peb tus qauv thiab qhov ntau thiab tsawg, uas tuaj yeem txwv lawv siv hauv qee yam kev siv. Kev cai cov duab thiab qhov ntau thiab tsawg tuaj yeem tsim tau, tab sis qhov no tuaj yeem ua rau tus nqi nce ntxiv.
4. Yooj yim rau chipping thiab tawg
Alnico hlau nplaum kuj tseem ua rau chipping thiab tawg, uas tuaj yeem txo lawv txoj sia thiab ua rau lawv ua tsis tiav. Qhov no tuaj yeem yog teeb meem hauv cov ntawv thov uas cov hlau nplaum raug rau lub cev kev ntxhov siab lossis kev co.
Xaus
Zuag qhia tag nrho, alnico hlau nplaum muaj ntau qhov zoo thiab qhov tsis zoo uas yuav tsum tau txiav txim siab thaum xaiv lawv rau ib daim ntawv thov tshwj xeeb. Thaum lawv paub txog lawv lub zog sib nqus siab, tsis kam mus rau demagnetization, thiab qhov kub thiab txias, lawv tuaj yeem raug nqi, nkig, thiab txwv ntawm lawv cov duab thiab qhov ntau thiab tsawg. Txawm hais tias cov teeb meem no, alnico hlau nplaum tseem yog qhov kev xaiv nrov rau ntau yam kev siv uas yuav tsum muaj cov hlau nplaum muaj zog.
