Zihlala ixesha elingakanani iimagnethi ze-neodymium

Iimagnethi ze-NdFeB, ezaziwa ngokuba ziimagnethi ze-NdFeB, ziikristale ze-tetragonal ezenziwe nge-neodymium, intsimbi, kunye ne-boron (Nd2Fe14B). Imagnethi zeNeodymium zezona zimagnethi zisisigxina ezikhoyo namhlanje kunye nezona zisetyenziswa zixhaphakileyo iimagnethi zomhlaba.

Ingaba iipropathi zemagneti zemagnethi ze-NdFeB zinokuhlala ixesha elingakanani?

Iimagnethi ze-NdFeB zinamandla aphezulu okunyanzeliswa, kwaye akusayi kubakho demagnetization kunye notshintsho lwemagnethi phantsi kwemeko yendalo kunye neemeko zemagneti ngokubanzi. Ukucinga ukuba imeko-bume ichanekile, iimagnethi aziyi kuphulukana nokusebenza okuninzi nasemva kokusetyenziswa ixesha elide. Ke kwisicelo esisebenzayo, sihlala singayinanzi impembelelo yexesha kwimagnetism.

Zeziphi izinto eziya kuchaphazela ubomi benkonzo yeemagnethi ze-neodymium ekusebenziseni imagnethi yonke imihla?

Zimbini izinto ezichaphazela ngqo ubomi benkonzo umazibuthe.

Eyokuqala bubushushu. Qiniseka ukuba unike ingqwalasela kule ngxaki xa uthenga iimagnethi. Iimagnethi ze-N zisetyenziswa ngokubanzi kwimarike, kodwa zinokusebenza kuphela kwindawo engaphantsi kwama-80 degrees. Ukuba iqondo lobushushu lidlula eli qondo lobushushu, i-magnetism iya kuba buthathaka okanye ikhutshwe ngokupheleleyo. Ekubeni intsimi yangaphandle yemagnethi yangaphandle yemagnethi ifikelela kwi-saturation kwaye yenze imigca eshinyeneyo yokungenisa imagnethi, xa ubushushu bangaphandle bunyuka, ifom yentshukumo eqhelekileyo ngaphakathi kwimagnethi iyatshatyalaliswa. Ikwanciphisa amandla angaphakathi okunyanzeliswa umazibuthe, oko kukuthi, imveliso yamandla kazibuthe enkulu itshintsha kunye nobushushu, kunye nemveliso yexabiso leBr elihambelanayo kunye nexabiso le-H nalo liyatshintsha ngokufanelekileyo.

Eyesibini ngumhlwa. Ngokubanzi, umphezulu wemagnethi ye-neodymium uya kuba nomaleko wokugquma. Ukuba ukutyabeka kwimagnethi yonakele, amanzi anokungena lula ngaphakathi kwimagnethi ngokuthe ngqo, nto leyo eya kubangela ukuba umazibuthe aruse kwaye emva koko akhokelele ekwehleni kokusebenza kazibuthe. Phakathi kwazo zonke iimagnethi, amandla okumelana nokubola kweemagnethi ze-neodymium angaphezulu kunawabanye oomazibuthe.

Ndifuna ukuthenga iimagnethi ze-neodymium zobomi obude, ndingakhetha njani umenzi?

Uninzi lweemagnethi ze-neodymium ziveliswa eTshayina. Ukuba ufuna ukuthenga iimveliso ezikumgangatho ophezulu, kuxhomekeke kumandla omzi-mveliso. Ngokwetheknoloji yokuvelisa, izixhobo zokuvavanya, ukuhamba kwenkqubo, uncedo lobunjineli, isebe le-QC kunye nezatifikethi zenkqubo yokulawula umgangatho zinokuhlangabezana nemigangatho yamazwe ngamazwe. I-Fuzheng ihlangabezana nje nazo zonke ezi meko zingasentla, ngoko kulungile ukusikhetha njengomvelisi weemagnethi ze-neodymium zabasetyhini.
