N45 qib neodymium hlau nplaum yog hom hlau nplaum uas muaj zog heev uas muaj nyob rau niaj hnub no. Lawv yog tsim los ntawm cov hlau uas muaj neodymium, hlau, thiab boron. Lawv kuj hu ua NdFeB.
Kab lus no tsom rau N45 neodymium hlau nplaum. Nws hais txog qhov lawv nyiam, vim li cas lawv muaj zog, tib neeg siv lawv li cas, thiab lwm yam. Nyeem ntawv kom paub txhua yam txog cov hlau nplaum ruaj khov uas muaj zog heev.
N45 Magnet yog dab tsi?
N45 yog hais txog qib tshwj xeeb ntawm cov hlau nplaum neodymium nrog cov khoom siv hluav taws xob siab tshaj plaws ntawm 45 MGOe thiab qhov siab tshaj plaws ua haujlwm kub ntawm 80 degree txog 200 degree.
Cov hlau nplaum Neodymium yog tsim los ntawm kev tswj cov khoom sib xyaw ntawm NdFeB alloy, uas ua rau muaj ntau qib sib txawv nrog cov khoom sib nqus sib txawv.
Lub npe 'N45' yog hais txog cov ntsiab lus tseem ceeb hauv qab no:
● N=Ua los ntawm Neodymium alloy
● 45=Cov khoom siv hluav taws xob siab tshaj plaws ntawm 45 megagauss-oersteds (MGOe)
Cov khoom siv hluav taws xob siab tshaj plaws qhia tias lub zog sib nqus siab tshaj plaws uas cov hlau nplaum tuaj yeem muab tau. Qhov siab dua tus lej no, qhov muaj zog ntawm cov hlau nplaum tag nrho cov khoom sib nqus.
Piv txwv li, N45 hlau nplaum nrog 45 MGOe muaj zog dua N42- qib neodymium hlau nplaum.
Puas yog N45 Magnets Strong?
N45 neodymium hlau nplaum yog cov hlau nplaum ruaj khov. Lawv muaj zog ntau dua li niaj zaus ceramic lossis ferrite hlau nplaum.
Cia kuv piav qhia dab tsi ua rau N45 hlau nplaum muaj zog hauv cov ntsiab lus yooj yim:
Ua ntej, N45 hlau nplaum tiv thaiv ua demagnetized zoo. Lawv muaj ib yam dab tsi hu ua "high coercivity." Nws txhais tau tias lawv cov hlau nplaum nyob ruaj khov rau lub sijhawm ntev heev yam tsis muaj zog.
Qhov thib ob, N45 cov hlau nplaum khaws cov hlau nplaum muaj zog tom qab lub zog hlau nplaum ploj lawm. Lawv muaj "siab remanence." Lawv cov hlau nplaum seem tom qab magnetizing muaj zog heev.
Qhov thib peb, N45 hlau nplaum tuaj yeem ua rau lub zog sib nqus loj hauv qhov chaw me me. Lawv muaj "siab zog ceev." Lawv lub zog sib nqus yog qhov loj heev rau lawv qhov me me.
Plaub, N45 hlau nplaum tuaj yeem tswj qhov kub siab txog 200 degree. Lawv cov hlau nplaum nyob ruaj khov txawm tias thaum cua sov. Qhov kev tiv thaiv kub no ua rau lawv muaj zog.
Thib tsib, N45 hlau nplaum tiv thaiv corrosion thiab xeb zoo heev. Lawv nyob ruaj khov thiab txhim khu kev qha, nyob hauv lawv qhov tseem ceeb.
Cov khoom tshwj xeeb no ua rau N45 hlau nplaum 5-10 lub sij hawm muaj zog dua cov hlau nplaum ceramic lossis ferrite. Lawv kev sib xyaw ua ke ntawm qhov muaj zog ua rau lawv tsis ntseeg lub zog sib nqus rau cov hlau nplaum me me.
Dab tsi yog qhov Field Strength ntawm N45 Magnet?
N45 hlau nplaum tuaj yeem ua rau cov hlau nplaum muaj zog heev. Lub zog ntawm lawv cov magnetic teb feem ntau yog nyob nruab nrab ntawm 1.2 txog 1.3 tesla. Tesla yog lub tsev siv los ntsuas qhov sib nqus lub zog. Ib tesla sib npaug 10,000 amperes ib 'meter'.
Yog li lub zog teb ntawm N45 hlau nplaum yog nyob ib ncig ntawm 12, 000 txog 13, 000 amperes ib meter. Qhov no yog tus lej siab heev piv rau lwm cov hlau nplaum.
Qhov no qhia tau hais tias N45 hlau nplaum tuaj yeem tsim cov kab hlau nplaum sib nqus heev thiab ua kom muaj zog heev ntawm lwm cov hlau nplaum lossis cov hlau ferromagnetic tso nyob ze.
Lub zog teb siab stems los ntawm cov khoom tshwj xeeb ntawm neodymium alloy thiab cov txheej txheem tsim khoom siv los tsim N45 cov hlau nplaum ruaj khov. Manipulating muaj pes tsawg leeg ntawm neodymium, hlau, thiab boron thaum lub sij hawm tsim khoom tso cai rau kev ua tiav qhov kev ntsuam xyuas muaj zog sib nqus.
Tsis tas li ntawd, qhov loj, zoo li, thiab kev taw qhia ntawm cov hlau nplaum kuj cuam tshuam rau tag nrho lub zog. Cov hlau nplaum loj spherical zoo li muaj zog dua. Cov hlau nplaum cylindrical kuj ua tau zoo dua li cov duab square lossis duab plaub. Kub yog lwm yam - lub zog teb ntawm N45 hlau nplaum txo qis ntawm kev ua haujlwm siab dua. Lub xub ntiag ntawm cov hlau nplaum nyob ze kuj tuaj yeem nce lossis txo lub zog ntawm lub zog raws li kev taw qhia.
