Yuav xaiv cov hlau nplaum zoo li cas?

Muaj 5 cov khoom siv hlau nplaum tseem ceeb muaj, nyob rau hauv kev txiav txim ntawm lub zog sib nqus los ntawm qhov tsis muaj zog mus rau qhov muaj zog: roj hmab hlau nplaum, ferrite hlau nplaum, Alnico hlau nplaum, SmCo hlau nplaum thiab NdFeB hlau nplaum. Cov hauv qab no yog cov lus piav qhia luv luv ntawm cov yam ntxwv ntawm txhua yam khoom siv los pab koj xaiv cov hlau nplaum zoo.

1, Roj hmab hlau nplaum

Cov khoom siv ntawm cov hlau nplaum zoo ib yam li roj hmab, nws tuaj yeem folded, curled thiab txiav los ntawm txiab, thiab cov xim ntawm cov khoom yog xim av tsaus. Qhov saum npoo kuj tuaj yeem txuas nrog PVC daim ntawv nplaum los yog coated nrog cov kua nplaum. Qhov dav ntawm txhua yob yog mus txog 75mm, ntev 100m, txheem thickness 1.5mm, thiab qhov dav ntawm daim ntawv square yog mus txog 600mm, ntev 30m, standard thickness 0.5 thiab 0.75mm. Cov hlau nplaum tuaj yeem ua rau ob sab nrog cov nplaum rau kev siv yooj yim. Crafts, kos npe boards, zaub boards, magnetic calendars, lag luam phaib, xov tooj phau ntawv, thiab lwm yam.

2, Ferrite

Cov hlau nplaum siv dav, pheej yig, tab sis kuj muaj zog hlau nplaum piv rau cov hlau nplaum roj hmab. Cov khoom nws tus kheej yog tawv thiab nkig, nrog tsaus grey nto. Round daim duab, voj voog duab, square duab, pobzeb puab. Muaj ntau qhov ntau thiab tsawg rau cov khoom siv tes ua, cov khoom siv adsorption, cov khoom ua si, motors, hais lus, thiab lwm yam.

3, Alnico thiab samarium cobalt hlau nplaum

Kev siv cov khoom siv hlau nplaum thaum ntxov hauv kev siv tshuab. Nws tuaj yeem siv rau qhov kub thiab txias, ze li 500 degrees Celsius. Tom qab ua tiav, qhov saum npoo yog stainless hlau zoo li ci xim. Round flake, cylindrical, square, horseshoe, thiab lwm yam cuab yeej, meters thiab kub ib puag ncig samarium cobalt tsis tshua muaj lub ntiaj teb hlau nplaum, cov khoom yog nkig heev, tab sis kub resistant, yuav siv tau ntawm 300 degrees Celsius. Round daim duab, voj voog duab, square duab, pobzeb puab. Ntau qhov ntau thiab tsawg muaj.

4, Neodymium hlau boron

Nws yog ib qho kev ua haujlwm siab tsis tshua muaj lub ntiaj teb hlau nplaum, tsis yog nkig li samarium cobalt, tab sis tsis kub li samarium cobalt hlau nplaum. Nws yog ib qho yooj yim heev rau oxidize ntawm chav tsev kub, yog li qhov saum npoo yuav tsum tau plated. Round, nplhaib, square thiab pobzeb duab. NdFeB hlau nplaum yog cov hlau nplaum uas muaj zog tshaj plaws muaj nyob rau niaj hnub no thiab tau siv ntau dua hauv cov khoom siv tsis zoo xws li cov hlau nplaum adsorption, khoom ua si, hniav nyiaj hniav kub, thiab lwm yam.
