Xaiv cov khoom siv hlau nplaum zoo
Kev xaiv cov khoom siv hlau nplaum zoo rau koj daim ntawv thov tuaj yeem nyuaj. Muaj ntau yam khoom siv hlau nplaum xaiv los ntawm, txhua tus muaj cov yam ntxwv sib txawv. Raws li cov kws tshaj lij hlau nplaum, nrog rau peb cov kev paub dhau los hauv cov hlau nplaum, peb tuaj yeem pab koj xaiv qhov raug.
Muaj ntau yam khoom siv, suav nrog cov hlau nplaum neodymium (NdFeB lossis lub ntiaj teb tsis tshua muaj), alnico hlau nplaum (AlNiCo), samarium cobalt (SmCo) lossis ferrite hlau nplaum (ceramic). Tsis tas li ntawd, muaj ntau qhov sib txawv xws li electromagnets, cov hlau nplaum hloov tau thiab cov hlau nplaum sib txuas. Xaiv cov khoom tsim nyog yog tus yuam sij rau txoj haujlwm ua tiav.
Muaj pes tsawg hom hlau nplaum muaj
Ib qho yooj yim kev faib tawm ntawm cov hlau nplaum no tuaj yeem ua raws li cov khoom sib txawv ntawm cov hlau nplaum sib txawv thiab qhov chaw ntawm lawv cov hlau nplaum. Cov hlau nplaum uas tseem sib nqus tom qab magnetization yog hu ua cov hlau nplaum ruaj khov. Qhov txawv ntawm qhov no yog electromagnet. Lub tshuab hluav taws xob yog cov hlau nplaum ib ntus uas tsuas yog coj zoo li cov hlau nplaum ruaj khov thaum nyob ze ntawm qhov chaw sib nqus, tab sis poob qhov cuam tshuam sai sai thaum tshem tawm.
Cov hlau nplaum tas mus li feem ntau muab faib ua plaub pawg raws li lawv cov ntaub ntawv: NdFeB, AlNiCo, SmCo thiab ferrite.
Neodymium hlau boron (NdFeB) - feem ntau hu ua neodymium hlau boron lossis NEO hlau nplaum - yog cov hlau nplaum uas tsis tshua muaj hauv ntiaj teb ua los ntawm alloying neodymium, hlau thiab boron, thiab yog cov hlau nplaum ruaj khov uas muaj zog tshaj plaws niaj hnub no. Tau kawg, NdFeB tuaj yeem muab faib ua sintered NdFeB, sib koom NdFeB, compression txhaj NdFeB thiab lwm yam. Txawm li cas los xij, feem ntau, yog tias peb tsis qhia meej hom Nd-Fe-B, peb yuav xa mus rau sintered Nd-Fe-B.
Samarium Cobalt (UA)SmCo) - tseem hu ua lub ntiaj teb tsis tshua muaj cobalt, lub ntiaj teb tsis tshua muaj cobalt, RECo thiab CoSm - tsis muaj zog li neodymium hlau nplaum (NdFeB), tab sis lawv muab peb qhov zoo. Cov hlau nplaum ua los ntawm SmCo tuaj yeem ua haujlwm ntau dua qhov kub thiab txias, muaj qhov kub thiab txias coefficient thiab tiv taus corrosion ntau dua. Vim tias SmCo kim dua thiab muaj cov khoom tshwj xeeb no, SmCo feem ntau siv hauv kev siv tub rog thiab dav hlau.
Aluminium-Nickel-Cobalt (AlNiCo) - Tag nrho peb lub ntsiab ntawm AlNiCo - txhuas, nickel thiab cobalt. Txawm hais tias lawv yog qhov kub thiab txias, lawv tau yooj yim demagnetized. Hauv qee qhov kev siv, lawv feem ntau hloov los ntawm cov hlau nplaum ceramic thiab cov hlau nplaum tsis tshua muaj hauv ntiaj teb. AlNiCo feem ntau siv nyob rau hauv lub neej txhua hnub rau kev siv nyob ruaj ruaj thiab qhia ntawv.
Ferrite- Ceramic lossis ferrite ruaj khov hlau nplaum feem ntau yog tsim los ntawm sintered hlau oxide thiab barium lossis strontium carbonate thiab pheej yig thiab yooj yim los tsim los ntawm sintering lossis nias. Qhov no yog ib qho ntawm feem ntau siv hom hlau nplaum. Lawv muaj zog thiab tuaj yeem yooj yim demagnetized.
Cov hlau nplaum tas mus li tuaj yeem muab faib ua pawg hauv qab no los ntawm kev sib txawv ntawm cov qauv sib txawv:
Sintering-yog kev hloov pauv ntawm cov khoom siv hmoov rau hauv lub cev ntom ntom thiab yog txheej txheem ib txwm ua. Cov neeg tau siv cov txheej txheem no ntev heev los tsim cov ceramics, hmoov metallurgy, cov ntaub ntawv refractory, ultra-high kub cov ntaub ntawv, thiab lwm yam. Feem ntau, lub cev ntom ntom tau los ntawm sintering tom qab cov hmoov tau molded yog polycrystalline cov ntaub ntawv nrog ib tug microstructure. muaj cov crystals, vitreous lom zem thiab pores. Cov txheej txheem sintering ncaj qha cuam tshuam rau cov qoob loo loj, qhov pore loj thiab cov duab thiab kev faib tawm ntawm cov ciam teb hauv microstructure, uas cuam tshuam rau cov khoom ntawm cov khoom.
Bonding - Bonding tsis yog ib tug tshwj xeeb version nyob rau hauv lub strictest kev nkag siab ntawm lo lus, raws li kev sib raug zoo yog kev sib raug zoo ntawm sintered cov ntaub ntawv ua ke los ntawm ib tug nplaum. Nyob rau hauv txoj kev no cov eddy tam sim no generated thaum lub sij hawm daim ntawv thov hlau nplaum tuaj yeem txo qis me ntsis, txhim kho qhov kev ntseeg siab ntawm cov hlau nplaum thaum thov.
Txhaj Molding - Txhaj tshuaj molding yog ib txoj hauv kev tsim cov duab rau cov khoom lag luam. Cov khoom yog feem ntau molded siv roj hmab txhaj molding thiab yas txhaj tshuaj molding. Kev txhaj tshuaj molding kuj tseem tuaj yeem muab faib ua kev txhaj tshuaj molding thiab tuag casting txoj kev. Siv kev txhaj tshuaj molding ua ib txoj hauv kev tsim khoom tuaj yeem muab tau ntau dua rau cov duab hlau nplaum. Vim yog cov khoom ntawm cov hlau nplaum lawv tus kheej, sintered hlau nplaum feem ntau nkig thiab nyuaj rau tsim rau cov duab tshwj xeeb. Txoj kev txhaj tshuaj molding feem ntau ua rau cov duab ntau dua los ntawm kev sib txuas nrog lwm cov ntaub ntawv.
Flexible Magnet- Cov hlau nplaum hloov tau yog cov hlau nplaum uas tuaj yeem khoov thiab deformed thiab nws cov khoom sib nqus nyob twj ywm. Cov hlau nplaum no feem ntau yog ua los ntawm cov ntaub ntawv hloov tau yooj yim, xws li roj hmab, polyurethane, thiab lwm yam, thiab sib xyaw nrog cov hmoov sib nqus kom ua rau lawv sib nqus. Tsis zoo li cov hlau nplaum ib txwm muaj, cov hlau nplaum hloov tau yooj yim dua thiab yooj yim dua, yog li lawv tuaj yeem txiav thiab khoov rau ntau yam duab raws li xav tau. Lawv kuj muaj zoo adhesion zog thiab yuav siv tau rau a
Solenoid: Qhov ntxeev ntawm cov hlau nplaum ruaj khov yog cov hlau nplaum, uas tuaj yeem hu ua cov hlau nplaum ib ntus. Hom hlau nplaum no yog ib lub kauj uas tsim lub voj los ntawm kev qhwv cov xov hlau nyob ib ncig ntawm cov khoom tseem ceeb, tseem hu ua solenoid. Los ntawm kev xa hluav taws xob los ntawm cov solenoid, cov hlau nplaum uas siv los ua cov hlau nplaum electromagnet tsim tawm. Lub zog sib nqus zoo tshaj plaws tshwm sim nyob rau hauv lub kauj, thiab lub zog ntawm daim teb nce nrog cov xov tooj ntawm cov coils thiab lub zog ntawm qhov tam sim no. Electromagnets hloov tau yooj yim dua thiab tuaj yeem kho cov kev taw qhia ntawm cov hlau nplaum raws li cov kev taw qhia ntawm qhov tam sim no, thiab tseem tuaj yeem kho lub zog tam sim no raws li qhov xav tau kom ua tiav lub zog magnetic teb
