Txoj kev tiv thaiv corrosion rau cov hlau nplaum muaj zog

Anti corrosion technology yog dav siv nyob rau hauv ntau lub teb, xws li nyob rau hauv lub teb ntawm hlau nplaum, raws li cov hlau nplaum muaj zog yog heev yooj yim rau corrode. Yog li ntawd, feem ntau cov khoom tsim yuav tsum tau electroplated los yog txau. Cov txheej txheem saum npoo av muaj xws li electroplating npib tsib xee (nickel tooj liab npib tsib xee), kub dip galvanizing, txhuas txheej, electrophoresis txoj cai, thiab lwm yam.
NdFeB yog ib qho khoom siv dav siv thiab tsim cov hlau nplaum sai heev. Cov hlau nplaum muaj zog tau siv dav txij li thaum lawv tsim thiab tsim, tab sis lawv tau siv tsis pub dhau 20 xyoo. Vim nws cov hlau nplaum siab thiab kev ua haujlwm yooj yim, tus nqi tsis siab heev, yog li nws qhov kev siv tseem ceeb tau nthuav dav. Tam sim no, kev lag luam neodymium hlau boron muaj zog hlau nplaum tuaj yeem ua tiav cov khoom siv hluav taws xob sib nqus ntawm 500000 kilowatts, uas yog 10 npaug ntawm ferrite.
Piv nrog rau lwm cov hlau nplaum ruaj khov ferrite cov ntaub ntawv xws li ferrite, cov hlau nplaum muaj zog muaj cov khoom sib nqus zoo heev. Nws cov khoom siv hluav taws xob hluav taws xob muaj ntau dua li lwm hom hlau nplaum, yog li nws tuaj yeem hu ua "thawj tiam hlau nplaum huab tais". Cov hlau nplaum muaj zog muaj lub zog siab saturation xeev coercivity BS (BS=16KGS) thiab ntau yam kev sib nqus crystallization HA (HA=73KOE). Neodymium hlau nplaum cov khoom siv dav siv hauv ntim khoom, cov khoom ua si me, khoom plig thiab kos duab, kev ua kis las thiab lub cev muaj zog sib nqus tswj tsheb, hluav taws xob motors, micro motors, hluav taws xob computers, ntsuas khoom, ntsuas vaj huam sib luag, maus taus, digital koob yees duab, moos, suab, khoom siv hluav taws xob, chaw ua haujlwm systems, far-infrared magnetic therapy, thiab ntau yam kev lag luam hauv lub neej txhua hnub.
Cov hlau nplaum muaj zog kuj yog cov khoom siv hlau metallurgy, thiab lawv txoj kev tsim khoom thiab kev ua haujlwm zoo ib yam li samarium cobalt. Tam sim no, qhov siab tshaj plaws ua haujlwm kub ntawm cov hlau nplaum muaj zog yog kwv yees li 180 degrees Celsius. Nyob rau hauv kev siv tej yam ntuj tso ib puag ncig hnyav, nws yog feem ntau pom zoo kom tsis txhob tshaj 140 degrees Celsius.
Qhov no yog lub zog hlau nplaum tiv thaiv corrosion uas txhua tus tau piav qhia meej. Vim nws cov hlau nplaum siab, cov hlau nplaum muaj zog siv ntau qhov chaw los hloov lwm cov khoom siv hlau nplaum kom txo cov khoom ntim. Yog tias siv cov hlau nplaum ferrite, qhov screen loj tam sim no yuav tsis yooj yim qis dua ib nrab ntawm lub cib.
