Tsis tshua muaj lub ntiaj teb Hlau nplaum Specs

Xam phaj Cobalt Magnet Txheej txheem cej luam thiab Specs:

Samarium Cobalt (SmCo) hlau nplaum tseem hu ua lub ntiaj teb tsis tshua muaj hlau nplaum Cobalt. Nws qhov kev ua haujlwm siab rau demagnetization thiab qhov kub thiab txias zoo ua rau SmCo siab kub hlau nplaum lossis Sm2Co17 hlau nplaum ua haujlwm ruaj khov nyob rau hauv qhov kub siab txog 350 ° C. Feem ntau tsis muaj txheej txheem yog qhov tsim nyog. Yog li ntawd SmCo hlau nplaum yog qhov kev xaiv zoo ntawm cov khoom siv hlau nplaum rau ntau qhov kev ua tau zoo xws li aerospace, motorsports thiab kev lag luam tsheb.

Hlau nplaum Kev Nyab Xeeb:

Tsis tshua muaj lub ntiaj teb cov hlau nplaum lossis cov tshuab sib nqus yog qhov muaj zog heev, yog li cov lus qhia txog kev nyab xeeb hauv qab no yuav tsum tau ceeb toom rau txhua tus neeg ua haujlwm uas yuav siv, tuav, lossis txheej txheem lawv kom tsis txhob muaj kev raug mob lossis raug mob rau cov hlau nplaum.

Nco ntsoov tias cov hlau nplaum uas tsis tshua muaj lub ntiaj teb cov hlau nplaum tau tswj tau thaum lawv los sib tiv toj los yog cov khoom siv hlau. Nws yog ib qho tseem ceeb rau hnav tsom iav kev nyab xeeb thiab lwm yam kev tiv thaiv uas tsim nyog thaum tuav cov hlau nplaum loj. Yuav tsum looj cov hnab looj tes tiv thaiv ib sab tes.

Ua kom cov hlau nplaum nyob deb ntawm thaj chaw ua haujlwm. Ua tib zoo saib thaum ua haujlwm nrog cov hlau nplaum. Tsis txhob ua haujlwm nrog cov hlau nplaum sib xyaw yog tias koj qaug cawv, tshuaj lossis tshuaj yeeb dej caw.

Cov twj siv hluav taws xob tsis zoo thiab cov cuab yeej yuav hloov pauv kev puas tsuaj los yog raug puas los ntawm lub zog sib nqus. Nco ntsoov khaws cov hlau nplaum sib nqus kom zoo nrug deb ntawm cov twj siv hluav taws xob. Kev xyuam xim tshwj xeeb yuav tsum tau siv yog tias ib tus neeg hnav cov tshuab ua kom lub nrawm, vim tias muaj zog sib nqus yuav ua rau cov khoom siv hluav taws xob sab hauv.

Tsis txhob nqos cov hlau nplaum lossis tso cov hlau nplaum hauv qhov chaw ncav cuag ntawm cov menyuam yaus lossis cov neeg laus lub hlwb. Yog tias nqos tau cov hlau nplaum, sab laj nrog kws kho mob thiab / lossis nrhiav kev kho mob sai.

Tsis tshua muaj lub ntiaj teb cov hlau nplaum yuav tsim cov nplaim taws los ntawm kev sib cuag hauv kev sib tuav, tshwj xeeb tshaj yog thaum tso cai cuam tshuam ua ke. Tsis txhob siv hlau nplaum ntiaj teb tsis tshua zoo nyob rau qhov chaw muaj pa taws heev vim tias lub txim taws tuaj yeem taws qhov chaw ntawd.

Tsis tshua muaj lub ntiaj teb hmoov yog combustible; tshwm sim kev sib tov tuaj yeem tshwm sim thaum cov hmoov ua kom qhuav. Yog tias sib tsoo, ib txwm ntub zom cov hlau nplaum kom tsis txhob tshwm sim qhov sib txuas ntawm qhov sib tsoo yws. Tsis txhob qhuav qhuav. Nco ntsoov tias muaj qhov cua tsim nyog thaum sib nqus hlau nplaum. Tsis txhob sim siv tshuab hlau nplaum siv cov cuab yeej sib txawv, vim qhov no tuaj yeem tsim chipping thiab tawg. Yuav tsum looj tsom iav qhov muag tas li.
