Cov pas nrig sib nqus yog tsim los ntawm cov tub ntxhais sib nqus sab hauv thiab cov khoom siv sab nraud, thiab cov tub ntxhais sib nqus yog tsim los ntawm cov cylindrical sib nqus hlau thaiv thiab cov hlau nplaum hlau nplaum. Feem ntau yog siv rau hlau pins hauv cov ntaub ntawv raw; Nws yog dav siv hauv kev lag luam tshuaj, khoom noj khoom haus, pov tseg rov siv dua, carbon dub thiab lwm yam.
Ib tug zoo sib nqus pas nrig yuav tsum tau muab sib npaug zos nyob rau hauv qhov chaw ntawm lub magnetic induction kab, thiab lub point tis ntawm lub siab tshaj plaws sib nqus induction siv yuav tsum sau tag nrho cov hlau nplaum pas nrig kom ntau li ntau tau, vim hais tias nws yog feem ntau muab tso rau hauv lub mobile khoom kis kab mob, Qhov saum npoo ntawm cov pas nrig sib nqus yuav tsum du, qhov kev tiv thaiv yuav tsum yog me me, thiab yuav tsum tsis muaj cov khoom tsim kev puas tsuaj rau ib puag ncig, kom tsis txhob muaj kuab paug thiab ib puag ncig.
Qhov chaw ua haujlwm ntawm cov pas nrig sib nqus txiav txim siab tias nws yuav tsum muaj qee qhov kev tiv thaiv corrosion thiab kub ua haujlwm, thiab qee lub sijhawm xav tau muaj zog sib nqus induction siv. Sib txawv sib nqus induction siv tau los ntawm kev siv cov ntawv qhia sib nqus nrog cov thicknesses sib txawv. Xaiv cov hlau nplaum sib txawv txiav txim siab qhov siab tshaj plaws magnetic induction zog thiab kub tsis kam ntawm cov hlau nplaum. Feem ntau, kev ua haujlwm siab NdFeB hlau nplaum yuav tsum tau ua kom tiav qhov chaw sib nqus induction zog ntawm ntau tshaj 10000 Gauss ntawm cov pa D25 sib nqus pas nrig. SmCo Magnet feem ntau xaiv rau qhov kub thiab txias resistant magnetic pas nrig thaum kub tshaj 150 ℃. Txawm li cas los xij, SmCo Magnet tsis raug xaiv rau cov hlau nplaum loj loj vim tias tus nqi ntawm SmCo Magnet yog siab heev.
Qhov sib nqus ntawm qhov sib nqus ntawm qhov sib nqus ntawm qhov sib nqus yog ncaj qha proportional rau qhov tsawg kawg nkaus qhov loj me uas tuaj yeem adsorbed, tab sis me me hlau impurities tuaj yeem ua rau muaj kev cuam tshuam loj hauv roj teeb, tshuaj thiab lwm yam haujlwm. Yog li ntawd, cov hlau nplaum uas muaj ntau tshaj 12000 Gauss (D110 - D220) yuav tsum tau xaiv. Lwm cov teb tuaj yeem xaiv cov qis dua.
Qhov tseeb saum npoo hlau nplaum tuaj yeem ncav cuag li 6000 ~ 11000 Gauss, uas tuaj yeem hloov kho raws li qhov tshwj xeeb ntawm cov neeg siv khoom. Vim yog siv ultra-high coercivity magneto, kaw nrog silica gel los yog argon arc vuam, thiab ua los ntawm kev siv tshuab tshwj xeeb.
Cov ncej ntom ntom ntawm cov hlau tshem tawm tau zoo, thaj chaw sib cuag loj thiab muaj zog sib nqus. Lub thawv tshem tawm hlau tuaj yeem kho raws li cov neeg siv khoom xav tau. Nyob rau hauv tus txheej txheem ntawm magnetic pas nrig sib cuag nrog cov kua, lub internal magnetic zog yuav irreversibly poob. Thaum qhov poob siab tshaj 30% ntawm qhov pib lub zog, cov hlau nplaum yuav tsum tau hloov.
Thaum cov pas nrig sib nqus nyob rau hauv kev sib cuag nrog cov kua, lub zog sib nqus sab hauv yuav ploj mus irreversibly. Qhov poob siab tshaj 30% ntawm qhov pib lub zog los yog cov ntawv hlau ntawm qhov chaw. Thaum cov yeeb nkab steel hlau tsis hnav thiab tawg, cov pas nrig hlau nplaum yuav tsum tau hloov, thiab cov pas nrig sib nqus nqus cov hlau nplaum tsis tuaj yeem ua haujlwm ntxiv. Cov hlau nplaum feem ntau yog nkig, thiab saum npoo yog coated nrog qee cov roj, uas ua rau muaj kuab paug ib puag ncig zoo. Cov tuam txhab sib nqus hlau nplaum hauv tsev feem ntau ua haujlwm rau 1-2 xyoos hauv qhov hnyav thiab 7-8 xyoo hauv lub teeb. Nws yog tsuas yog siv hauv plastics, khoom noj khoom haus, kev tiv thaiv ib puag ncig, pom, tshuaj lom neeg kev lag luam, hluav taws xob, khoom siv hauv tsev, ceramics, tshuaj, hmoov, mining, thee thiab lwm yam lag luam.
