Hlau Nplhaib

Raws li Neodymium hlau nplaum yog kev txhav tas, feem ntau nws nyiam ua kom muaj kev tiv thaiv. Ntawm ntau qhov kev xaiv rau coatings, npib tsib xee thiab tooj lais-tooj-nickel yog feem ntau siv, ua cov hlau nplaum ntau corrosion resistant thiab ruaj.

Kev Taw Qhia Magnetization

Peb cov khoom magnet tuaj yeem nqa tau magnetized thiab un-magnetized. Qee txoj kev ntau ntau yuav tsum tau siv cov hlau nplaum ntoos ua ke rau hauv kev sibtham hauv ib lub xeev uas tsis muaj kev sib txuas thiab tom qab thaum lub rooj sib txoos tiav. Muaj ntau qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov hlau nplaum sib txawv.

Kev Sau Npe Kev Tshawb Fawb

Raws li neodymium hlau nplaum yog qhov khoom siv ua khoom siv, cov tub lag luam yuav xav kom muab cov lus qhia hauv qab no kom thiaj li tau txais cov lus qhia los ntawm peb.

Ntau cov lus nug lossis kev txhawj xeeb txog peb cov khoom, pub dawb rau NYIAM no rau cov lus tshaj tawm sai tshaj no.

Lus nug

1. Dab tsi yog qhov zoo tshaj plaws ntawm cov hlau nplaum?
Neodymium (ntau dua Neodymium-Iron-Boron) cov hlau nplaum yog cov khoob khoob loj tshaj plaws nyob hauv lub ntiaj teb.

2. Cov hlau nplaum neodymium yog dab tsi? Yog lawv tib yam li "tsawg lub ntiaj teb"?
Neodymium cov hlau nplaum yog ib tug tswv cuab ntawm tsev neeg tsawg heev hlau nplaum. Lawv raug hu ua "tsis muaj lub ntiaj teb" vim hais tias neodymium yog ib tug tswv cuab ntawm "lub ntiaj teb tsis tshua muaj" cov ntsiab lus ntawm cov lus qhia. Neodymium cov hlau nplaum yog cov lusteb ntawm cov hlau nplaum lub ntiaj teb tsis tshua muaj thiab yog cov khaus khaum tshaj plaws hauv ntiaj teb.

3. Dab tsi yog Qeb ntawm cov hlau nplaum?
GME Neodymium Permanent Magnet yog cov qhab nia raws li lawv lub zog ntau zog, uas muaj feem xyuam rau qhov sib nqus cov pa tawm ntawm lub cev ntim tau. Ntau dua qhov tseem ceeb qhia tau hais tias muaj zog hlau nplaum thiab ntau ntawm N35 mus txog N52. thiab M, H, SH, UH, EH, AH series, tuaj yeem ua kev lomzem rau ntau hom duab thiab qhov ntau thiab tsawg ntawm kev ncaj ncees. Ntau txoj kev xaiv ntawm coatings thiab cov txuj ci magnetization tuaj yeem ua tau raws li tus neeg yuav tsum tau muaj. Cov ntawv tom qab qib kawm qhia seb qhov kub siab tshaj (feem ntau Curie kub), uas muaj ntawm M (txog 100 ° C) txog EH (200 ° C) mus txog AH (230 ° C)

4. Cov ntaub ntawv magnet nyiam dab tsi?
Cov ntaub ntawv ntawm Ferromagnetic pom zoo los ntawm lub zog sib nqus. Cov hlau (Fe), cov xim nickel (Ni), thiab cobalt (Co) yog qhov feem ntau muaj nyob. Hlau yog ferromagnetic vim hais tias nws yog ib qho hlau alloy ntawm hlau thiab lwm yam hlau.

5. Kuv yuav siv cov ntaub ntawv twg los thaiv / tiv thaiv magnetic teb?
Sib nqus liaj teb tsis tuaj yeem muab thaiv, tsuas yog raug xa mus. Tsuas yog cov ntaub ntawv uas yuav ua rau reducture magnetic fields yog cov khoom ferromagnetic (attracted rau cov hlau nplaum), xws li hlau, hlau (uas muaj hlau), cobalt, thiab xee npais. Cov teeb meem ntawm kev hloov tshiab yog qhov sib luag rau cov khoom permeability. Cov khoom siv zoo tshaj plaws yog cov xom tooj 80, tom qab 50 lub tsev neeg Nickel.

6. Lub zog ntawm cov hlau nplaum tau li cas?
Gaussmeters yog siv los ntsuas qhov sib txawv ntawm qhov chaw magnetic ntawm qhov chaw ntawm cov hlau nplaum. Qhov no raug xa mus rau sab nraud thiab raug ntsuas hauv Gauss (lossis Tesla). Tsav Quav Teeb Meem siv los ntsuas qhov tuav lub zog ntawm ib lub hlau nplaum uas yog nyob rau hauv kev sib cuag nrog ib tug ca steel phaj. Tsav rog yog ntsuas hauv phaus (los yog kilograms).

7. Kuv puas tau txiav, xyaum, lossis cav neodymium hlau nplaum?
Lub Neodymium Hlau Boron khoom yog ib qho nyuaj heev thiab brittle, yog li machining nyuaj rau qhov zoo tshaj plaws.
