Cov hlau nplaum neodymium tsis tshua muaj ntiaj teb yog dab tsi?

Cov hlau nplaum neodymium uas tsis tshua muaj neeg paub, tseem hu ua NdFeB hlau nplaum, yog cov hlau nplaum ruaj khov muaj zog tshaj plaws niaj hnub no. Lawv muaj cov neodymium, hlau, thiab boron sib xyaw ua ke, thiab tau tsim thawj zaug hauv xyoo 1982 los ntawm Sumitomo Special Metals. Cov hlau nplaum no muaj ntau yam zoo dua li cov hlau nplaum ib txwm muaj, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv hauv kev lag luam thiab kev lag luam.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov hlau nplaum neodymium yog lawv lub zog zoo kawg nkaus. Lawv muaj cov khoom siv hluav taws xob siab heev, uas tuaj yeem tshaj 50 MGOe (Mega Gauss Oersteds). Qhov ceev zog siab no tso cai rau cov hlau nplaum no tsim cov teb sib nqus muaj zog dua li lwm hom hlau nplaum, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau lub zog sib nqus muaj zog.

Lwm qhov zoo ntawm NdFeB hlau nplaum yog lawv qhov kev hloov pauv tau yooj yim. Lawv tuaj yeem ua tau ntau yam duab thiab qhov ntau thiab tsawg, suav nrog cov blocks, discs, cylinders, rings, thiab txawm tiaskev cai duabQhov kev hloov pauv no tso cai rau lawv siv rau ntau yam kev siv, los ntawm cov cuab yeej kev lag luam mus rau cov khoom siv rau cov neeg siv khoom.

Cov hlau nplaum neodymium kuj tseem tiv taus demagnetization heev. Lawv muaj lub zog coercivity siab, uas txhais tau tias lawv xav tau lub zog sib nqus muaj zog heev kom demagnetized. Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau lub zog sib nqus tas mus li, xws li hauv cov khoom siv kho mob, hard disk drives, thiab cov tshuab suab siab.

Txawm hais tias lawv muaj ntau yam zoo, cov hlau nplaum neodymium kuj muaj qee qhov teeb meem. Lawv yog cov brittle heev thiab tuaj yeem tawg lossis chip yooj yim, yog li lawv yuav tsum tau ua tib zoo saib xyuas. Lawv kuj yooj yim rau xeb thiab xav tau ib txheej tiv thaiv kom tsis txhob xeb lossis puas tsuaj.

Xaus lus, cov hlau nplaum neodymium yog ib qho kev nce qib tseem ceeb hauv kev siv tshuab hlau nplaum. Lawv muab kev sib xyaw ua ke zoo dua ntawm lub zog, kev hloov pauv tau yooj yim, thiab kev tiv thaiv demagnetization, ua rau lawv zoo tagnrho rau ntau yam kev siv. Txawm hais tias lawv muaj qee qhov kev cov nyom, cov txiaj ntsig ntawm cov hlau nplaum neodymium ntau dua li qhov tsis zoo, ua rau lawv yog cov cuab yeej tseem ceeb rau cov engineers, cov kws tshawb fawb, thiab cov chaw tsim khoom thoob ntiaj teb.
