Yuav ua li cas xaiv cov hlau nplaum?
Cov hlau nplaum hnyav tshaj plaws niaj hnub no yog cov hom av tsis tshua muaj. Cov no yog, kom muaj zog ua kom lub zog loj, ua kom yooj yim, Ceramic, Alnico, Samarium, thiab Hom Neodymium. Ntawm lub ntiaj teb tsis tshua muaj, Neodymium-Iron-Boron hlau nplaum yog qhov tseem ceeb tshaj plaws. Txawm li cas los xij, ntawm qhov siab (ntawm kwv yees li 200 degree C thiab saum toj), Samarium Cobalt hlau nplaum yuav ua tau zoo dua li cov Neodymium-Iron-Boron (nyob ntawm qhov sibluag sib nqus).
Cov lus qhia hauv qab no piav qhia txog cov khoom ntawm txhua hom los pab koj txiav txim siab txog yam koj xav tau.
1. Flexible
Ib daim ntawv tshwj xeeb ntawm cov khoom ferrite lossis tsis tshua muaj hauv av. Cov ntaub ntawv yooj yim cov hlau nplaum raug tsim los ntawm kev sib tsoo ferrite lossis tsis tshua muaj lub ntiaj teb magnet hmoov nyob hauv ntau yam khoom, xws li yas.
Yam ntxwv: Cov ntaub ntawv yooj yim magnet zoo li cov roj hmab, thiab xim dawb los yog xim dub. Cov khoom siv pheej yig no tuaj yeem bent, coiled thiab twisted, thiab yooj yim txiav nrog rab riam los yog txiab. Ob leeg lub nplhaib thiab cov ntawv sib nqus sib nqus muaj ob daim ntaub nplaum rau cov ntaub ntawv yooj yim. Cov ntaub ntawv laminated nrog cov ntaub hlua dawb tuaj yeem ua luam siv silk screening lossis digital printing techniques.
Qhov Luaj Loj thiab Daim Qauv: Cov kab thiab cov nplooj ntawv: ib daim hlab mus txog 3 "dav los ntawm 400" ntev, thiab qhov raug tuab yog 1/16 "; cov ntawv txheeb yog feem ntau 24 "dav, 100 'ntev, thiab cov tuab tuab li ntawm 0.02" thiab 0.03 ".
Daim ntaub ntawv: Feem ntau siv cov khoom siv tes ua, ntawv sau npe, kos npe, pom cov duab, nyiaj them, muag khoom siv, chaw ua lag luam, DIY tsev cov haujlwm, qhov kev kho mob qhov rai thiab ntau dua.
2. Tej hub
Ua los ntawm barium lossis strontium ferrite, cov khoom siv hlau nplaum (ferrite) yog cov khoom siv ntau tshaj, cov nqi qis tshaj hnub no.
Yam ntxwv: Zoo siab nyob rau hauv sib nqus lub zog, thiab pom zoo tiv thaiv rau demagnetization, ceramic magnets yog nrov rau ntau daim ntawv thov kev pab. Cov khoom no yog ib qho nyuaj, txhav, thiab tsaus tsaus hauv xim.
Qhov Luaj Luaj thiab Teeb: Discs, rings, blocks thiab arc ntu cov ntawv.

3. Alnico
Kev ua txhuas ntawm aluminium, nickel, thiab cobalt, Alnico magnet cov ntaub ntawv tau nrov vim tias xyoo 1930. Alnico hlau nplaum yog siv hauv kev siv kev ua haujlwm, qhov chaw sov kub yog qhov tseem ceeb.
Yam ntxwv: Zoo heev rau cov kev ntsuas kub siab txog li ntawm 1000 ° F, qhov seem qis, thiab kev tiv thaiv corrosion. Khaws cov hlau nplaum alnico kuj tuaj yeem tsim ua rau cov qauv sib txawv.
Qhov ntau thiab ntau ntau: Cov duab , rods, tuav, thiab horseshoes.
Daim ntaub ntawv: Feem ntau siv hauv Meters, thiab rau kev tuav tswj tshwj xeeb, kev siv kub-txias.
4. Samarium Cobalt (SmCo)
Ib chav kawm txog cov khoom tsis tshua zoo hauv lub ntiaj teb, SmCo cov khoom siv magnet tau pib thaum xyoo 1970. Hnub no, SmCo cov hlau nplaum yog feem ntau siv rau cov ntawv thov uas yuav tsum tau siv cov cua txias thiab xav tau cov khoom sib nqus siab.
Yam ntxwv: Cov khoom sib nqus sib nqus, muaj zog heev, tab sis tuaj yeem siv tau siv thaum kub txog 500 ° F.
Qhov Luaj Lawm Thiab Ntev: Discs, blocks, thiab rings.
Daim ntaub ntawv: Feem ntau yog siv rau kev kho mob siab dua thiab kev kub siab.
Neodymium Hlau Boron (NdFeb)
Lub ntiaj teb tsawg hom hlau nplaum cov khoom uas muaj cov khoom sib nqus siab tshaj plaws, nws yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv hlau nplaum uas muaj niaj hnub no.
Yam ntxwv: Tsis yog raws li nkig li SmCo, tab sis yuav tsum tsis txhob siv rau qhov kub tshaj 300 tawm F, tsis muaj kev tsim tshwj xeeb tsim. Neo magnet cov ntaub ntawv yuav ua kom yooj yim hauv qee yam kev mob, yog li nws yog qhov zoo tshaj plaws los tiv thaiv lub nplhaib ntawm plating los yog txheej.
Qhov Luaj Lawm thiab Ntev: Discs, blocks, rings thiab rods.
Daim ntaub ntawv: Qhov zoo tshaj plaws rau ob qho tib si, thiab cov ntawv tsis yog kev siv xws li tuav, sib nqus cov hniav nyiaj hniav kub, khawm thiab ntau dua.
Ntxiv rau cov tsev neeg tau sau tseg saum no, muaj ntau qib hauv txhua tsev neeg. Rau feem ntau cov ntaub ntawv tsis yog kev siv, qib nws tsis tseem ceeb heev. Cov hlau nplaum uas tau qhia hauv MagnetShop.com tau raug xaiv rau kev khwv nyiaj txiag thiab kev siv cov ntaub ntawv.
Cov hlau nplaum npaum li cas?
Indialual Induction (muab lub cim Br, thiab ntsuas hauv Gauss). Qhov no yog qhov qhia txog tias muaj zog npaum li cas hauv cov hlau nplaum muaj peev xwm ua tau.
Coercive Force (muab lub cim HC, thiab ntsuas hauv Oersteds). Qhov no yog qhov qhia txog tias nws nyuaj npaum li cas rau txoj kev tsis sib haum.
Khoom Tshaj Lij Khoom Siab (muab lub cim BHmax, thiab ntsuas hauv Gauss-Oersteds). Qhov no yog qhov qhia txog qhov khoom ntim ntawm cov khoom siv hlau nplaum uas yuav tsum tau ua kom tsim ib theem ntawm cov leeg sib nqus.

Yuav ua li cas xaiv ib tug hlau nplaum?
Muab cov hlau nplaum loj npaum li cas, koj tuaj yeem kwv yees tias ntau npaum li cas magnetic flux ntau cov ntaub ntawv yuav tawm ntawm qhov chaw ze lossis koj tuaj yeem siv cov ntaub ntawv no los sib piv ib cov khoom rau lwm tus.
Piv txwv: Qhov ntau npaum li cas yuav ua kom muaj Neo 35 ib qho li piv rau Ceramic 5 ntawm tib qhov loj ntawm qhov muab nrug? Tsuas faib cov Br ntawm Neo 35 los ntawm Br ntawm Ceramic 5 (12,300 / 3,950) kom tau 3.1. Qhov no txhais tau hais tias Neo 35 yuav muab rau koj 3.1 zaus ntawm cov lus qhwv ib Ceramic 5 tib lub loj yuav nyob rau ntawm ib qho chaw ze.
Muab qee lub cev yuav tsum tau nyob hauv qee qhov chaw ntawm cov hlau nplaum, koj tuaj yeem siv cov ntaub ntawv no los laij seb lub hnab ntim ntau npaum li cas yuav tsum muaj rau cov khoom siv hlau nplaum sib txawv.
Piv txwv: Qhov ntau npaum li cas ntawm Ceramic 5 hlau nplaum yuav muab tib yam dej ua ib Neo 35 hlau nplaum rau ntawm qhov chaw deb? Tsuas yog faib BHmax ntawm Neo 35 los ntawm BHmax ntawm Ceramic 5 (35 / 3.6) kom tau 9.7. Qhov no txhais tau hais tias qhov ntim ntawm Ceramic 5 hlau nplaum yuav tsum yog 9.7 npaug ntawm Neo 35 hlau nplaum muab rau koj tib yam dej.
Dab tsi yog qhov siab tshaj pom kev siv zog ua haujlwm rau cov hlau nplaum sib txawv?
Qhov siab tshaj plaws uas qhov hlau nplaum yuav siv tau yog nyob ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov hlau nplaum lub hlau nplaum. Tshaj tawm no yog kwv yees ua haujlwm siab tshaj plaws rau ntau chav kawm ntawm cov khoom siv hlau nplaum. Thaum sov ze rau cov neeg uas tau teev tseg ntawm no, yuav tsum tau ua tib zoo saib kom paub meej tias cov hlau nplaum yuav tsis ua pa lawm.
