Cov raj hlau nplaum Feem ntau yog siv los lim ntau cov hmoov zoo thiab cov kua dej, cov hlau tsis huv, thiab lwm yam khoom sib nqus hauv cov kua dej, thiab tau siv dav hauv tshuaj, khoom noj khoom haus, pov tseg rov ua dua, carbon dub, thiab lwm yam. Ib lub hlau nplaum zoo yuav tsum muaj cov kab sib nqus sib nqus sib nqus sib nqus, thiab kev faib tawm ntawm cov khoom sib nqus siab induction yuav tsum sau tag nrho cov khoom sib nqus kom ntau li ntau tau vim nws feem ntau muab tso rau hauv cov khoom txav khoom sib kis. Ib puag ncig cov khoom tsis zoo, zam cov pa phem thiab ib puag ncig. Qhov chaw ua haujlwm txiav txim siab tias nws yuav tsum muaj qee yam kev tiv thaiv corrosion thiab cov yam ntxwv ntawm qhov kub thiab txias, thiab qee lub sijhawm yuav tsum muaj zog sib nqus induction.
Qhov sib nqus induction qhov sib nqus ntawm qhov sib nqus pas nrig yog proportional rau qhov loj ntawm cov khoom me me uas tuaj yeem adsorbed. Hauv thaj chaw xws li roj teeb thiab tshuaj, me me hlau impurities kuj muaj kev cuam tshuam loj, yog li yuav tsum siv 12000 gausses. Lwm thaj chaw tuaj yeem xaiv qis dua. Cov yam ntxwv yog tuab sib nqus hlau nplaum ncej, cov hlau tshem tawm cov nyhuv zoo, thaj chaw sib ze loj, thiab muaj zog sib nqus. Lub thawv tshem tawm hlau tuaj yeem hloov kho thiab ua tiav raws li cov neeg siv khoom xav tau.
Feem ntau yog siv rau hauv plastics, zaub mov, kev tiv thaiv ib puag ncig, pom, tshuaj lom neeg kev lag luam, hluav taws xob fais fab, khoom siv hauv tsev, ceramics, tshuaj, hmoov, mining, thee, thiab lwm yam lag luam.
Yuav tiv thaiv cov hlau nplaum ntawm cov hlau nplaum li cas
Lub bar hlau nplaum muaj qib ntawm cov hlau nplaum, uas koj tuaj yeem qhia los ntawm kev siv nws. Txawm li cas los xij, raws li nws siv, nws cov khoom sib nqus yuav maj mam txo, tab sis yog tias nws cov khoom sib nqus txo qis, nws yuav tsis zoo rau nws siv. Yuav tiv thaiv nws cov hlau nplaum li cas?
1. Tsis txhob cia lub magnetic wand txav ceev, xws li tsoo lossis tsoo.
2. Khaws kom deb ntawm qhov kub thiab txias.
3. Khaws cov nplaum nplaum kom deb ntawm qhov chaw sib nqus.
4. Tsis txhob ua cua sov ntawm qhov kub thiab txias.
Tom qab ntawd txhawm rau tiv thaiv cov hlau nplaum ntawm cov hlau nplaum, ntxiv rau kev siv lawv kom raug, lwm txoj hauv kev yog kom cov hlau nplaum sib nqus kom deb ntawm qee qhov tsis zoo thiab tsis txhob siv lawv nyob rau hauv cov xwm txheej hnyav. Ua haujlwm zoo tiv thaiv lub zog sib nqus, txhawm rau ua kom lub neej ua haujlwm ntev.
Cov hlau nplaum yog cov khoom uas tuaj yeem tsim kom muaj zog sib nqus. Nws tuaj yeem siv dav hauv ntau qhov kev lag luam thiab muaj cov yam ntxwv zoo.
Txheej txheem Magnetization
1. Rov qab hloov pauv ntawm cov phab ntsa. Nyob rau hauv cov ntaub ntawv ntawm ib tug me me sab nraud magnetic teb, rau sib nqus domains uas nws spontaneous magnetization kev taw qhia yog tib yam li ntawm sab nraud magnetic teb los yog nyob rau hauv ib tug me me lub kaum sab xis, lub sib nqus domains yuav nthuav vim lub tsawg magnetostatic zog ntawm lub bar hlau nplaum. Hloov chaw, cov hlau nplaum uas tshwm sim nyob rau hauv qhov kev taw qhia rau sab nraud magnetic teb. Los yog lub sib nqus domain shrinks ntawm obtuse lub kaum sab xis.
2. Kev hloov pauv tsis tau ntawm cov phab ntsa.
3. Kev sib hloov ntawm cov khoom sib nqus thiab lub sijhawm sib nqus. Cov txheej txheem yog ua kom cov magnetocrystalline anisotropy nce thiab ua haujlwm kom nws nyuaj rau tig thiab cov hlau nplaum tsis muaj zog.
4. Paramagnetic magnetization theem. Txawm hais tias qhov loj ntawm qhov chaw sib nqus sab nraud, qhov nce hauv magnetization yog me me. Qhov nce hauv qhov sib nqus ntawm cov hlau nplaum bar yog ib feem vim qhov kev hloov pauv ntawm lub sijhawm sib nqus ntawm lub sijhawm thiab ib feem yog vim kev txhim kho qhov tsis sib xws ntawm lub hauv paus sib nqus lub sijhawm hauv cov khoom sib nqus.
Kev ceev faj rau cov hlau nplaum muaj zog:
1. Thaum siv, ua tib zoo saib xyuas qhov huv ntawm qhov chaw ua haujlwm thiab tsis txhob siv cov khoom sib nqus me me xws li cov ntaub ntawv hlau. Nws yog tus cwj pwm los ntawm kev nyuaj thiab nkig, nws qhov nqus dej tuaj yeem ncav cuag ntau dua 600 npaug ntawm nws qhov hnyav, thiab nws yooj yim rau absorbed thiab puas. Yog li ntawd, kev sib tsoo thiab kev puas tsuaj yuav tsum tau zam thaum ua haujlwm.
2. Thaum khaws cia, ib puag ncig rau khaws cov hlau nplaum yuav tsum tau ua kom cua thiab qhuav, vim nws yooj yim rau xeb hauv qhov chaw ntub dej. Qhov ntsuas kub tsis tuaj yeem tshaj qhov ntsuas kub ua haujlwm. Tsis tas li ntawd, cov khoom uas tsis yog-plated yuav tsum tau oiled kom zoo thaum lub sij hawm cia kom tsis txhob xeb.
