Ngaba kunokwenzeka ukuba ukuvelisa iimagnethi neodymium ngezandla zakho?

Izazinzulu ziye kudala uzama ukwenza umazibuthe superstrong ngokusekelwe aluminium ezahlukeneyo. Kodwa ke uninzi phuhliso kwafuneka ukuba ukusebenzisa izinto ezinokuba yingozi ebantwini. Ekugqibeleni wakwazi ukufumana inxalenye ngokusekelwe neodymium. Le umhlaba metal enqabileyo ayidali usongo empilweni. Yibani wayeqhelene iimpawu ezizodwa le nto, abantu abaninzi bacinga ukuba kunokwenzeka ukuvelisa iimagnethi neodymium ngezandla zabo. Ngokutsho ingcamango - yinkqubo entsonkothileyo ngokwemiqathango zobugcisa. Okanye ungakwenza oko zivela kwizinto ezingekenziwa eziziisekondari esirisayikilishiweyo?

Neodymium iimagnethi: yintoni na le nto?

Ngokutsho izazinzulu, oku wathabatha malunga-20 iminyaka yophando kunye nokuvavanywa. Ukukhethwa kwezinto sithabathela ingqalelo izinto ezininzi: zofikelelo losetyenziso, ukuziqhelanisa, ukhuseleko, iimpawu eziphakamileyo owahluke ngokwemvelo, ukumelana neemeko zokusingqongileyo. ulwalathiso nathembisayo izazinzulu ingqalelo ukusetyenziswa zesinyithi ezinqabileyo zomhlaba. Neodymium ngenxa yale njongo waya kanye ngokugqibeleleyo.

Oku kusekelwe umazibuthe kufuneka amandla ngokumangalisayo adhesion. Kaloku imali encinci izinto ikwazi ephethe ubunzima amaxesha amaninzi ngaphezu ubunzima bayo. Iipropati Magnetic zigcinwa ixesha elide (lako hayi ngaphezulu kwe-2% kwiminyaka 10 ukusetyenziswa). Ngoku iimagnethi neodymium zingathengwa kwiivenkile elithile. Amaxabiso ziyafumaneka phantse nabani.

isakhiwo

Iimagnethi ngokwesiseko umhlaba enqabileyo metal Nd2Fe14B ezipalini zibonakaliswe ifomula. Isakhiwo luquka neodymium (Nd), yentsimbi (Fe), boron (B). technology osemqoka ukuba umhlaba metal ezinqabileyo kwifomu yayo enyulu kunzima ukuchonga. Inkqubo sintering kunye namanye amacandelo kwifomu umgubo kufuneka kwenzeke phantsi imeko egalelwe. Kungenjalo igcwala ngamandla kwenzeka kulahleka kwiipropati.

Technology for iimeko eziqhelekileyo kunzima, ngoko zama ukwenza neodymium iimagnethi ngezandla zabo engafanelekanga. Abhalwe iimveliso kule kwimveliso. Inani emva oonobumba N (25, 30, 45) ibonisa ikhowudi. I aphezulu amanqaku, ngokuqina iimpawu kazibuthe mbandela. Inani zixhomekeke lobushushu eliphezulu yokusebenza ye umazibuthe.

iimpawu

Ukuthintela iimeko zokusingqongileyo zinefuthe umazibuthe ziyabandakanywa yi sisincoko olukhuselayo. Ngokuqhelekileyo, bobabini inwebu nickel okanye ephuculiweyo nguqulo ne maleko olongezelelweyo eliphakathi zezobhedu. Enye inkalo ebalulekileyo - iimagnethi neodymium kwiqondo lobushushu kwama-70 ° C baqalisa ukuba demagnetized. Egqithayo iinqobo umda kunokukhokelela ilahleko olupheleleyo lwe mpahla kunye yenguqu ingxubevange in intwana ngentsimbi.

Ingakumbi umbandela kufuna amanyathelo okhuseleko ekhethekileyo emsebenzini. Umzekelo, iimagnethi neodymium abe 50x30 mm ngcina amandla ka 100 - 115 kg, kwaye 70x50 mm kunye kg 300. Ukuphathwa gadalala ukuba enokubangela umonakalo: ukuze iminwe yakho itshe, ukulimaza ulusu, umonakalo ithambo. yokungqubana kwamalweyile ngendlela oomazibuthe ababini ukuze nokonakala kwezinto zokufunda kunye nokusekwa ziingceba ezibukhali ukuba buhlungu amehlo akho.

isicelo

Ngokwesiko ke zisetyenziswa kwizixhobo ze-elektroniki, apho ufuna ukwenza sibubona osisigxina. iipropati Amanqaku bakwazi ukuzisebenzisa ngempumelelo ekufumaneni kwaye uphakamisa into netyhidiweyo ukusuka ezantsi okugcina amanzi. izakhiwo ezinjalo ngaphandle kokuba eqwalasele umntu lugs intambo zifakwa eyebolt leyo nje kuyimfuneko kuba xa kokujikeleza ivumela disengaging ezimbini umphezulu oluhamba ngamandla.

Iimagnethi zenziwa kunye nobukhulu mm-1 ukuya kwezili-120 ububanzi yaye nezilwanyana ezohlukeneyo ubukhulu kunye nokumila. I ubalaseleyo kubo ezisetyenziswa kakhulu impahla yesikhumba kunye namashishini ifanitshala. Ke ingafunyanwa kwi zokudlala fun kunye nezixhobo ilenga izinto ezahlukeneyo. iimagnethi ezinamandla azohlukaniswa yokuhluza granular kunye nezinto lulwelo. Zisetyenziswa wokubamba olusezimbizeni ukuhamba ukungcola zentsimbi kunye izinto kwamanye amazwe.

bond High amandla ikhuthaza abantu ukuba basebenzise kwabo "zokusindisa 'xa usebenzisa amanzi kunye negesi. Ngokuthenga iimagnethi neodymium ngenxa zokubala, ke, ngoko, ukuzama ukufezekisa linyuke okanye ukuyeka njengokujikeleza indlela. Le ithuba ifumaneka isondlo kwezinye izixhobo apho kuyimfuneko emalungwini zentsimbi le. umazibuthe enamandla elapha kwindawo ethile emzimbeni, ezinokucothisa njengokujikeleza impeller.

Ngaba kunokwenzeka ukuba ukuvelisa iimagnethi neodymium ngezandla zakho?

technology Industrial ngaphandle sintering ubunzima ingxubevange, ndingena elukhuni kwaye ingafikeleleki kwimekobume ikhaya inkqubo magnetization ngenxa kweziyobisi. Lisebenzisa amasimi namandla kakhulu. Ukuba ndamvuselela kakhulu ukuba wena iimagnethi neodymium, izandla zakho ungenza unokwenjenjalo sichitha bombane kwinkulungwane "lixesha '.

Kwezinye nzima drives emidala ingafunyanwa ngaphakathi omnye - ezimbini izinto ezincinane. Ukuzama ukubhola okanye yaphule iimagnethi ezinjalo usebenze. Umphezulu Umaleko yokuzikhusela yonakele, impahla idityaniswe okusingqongileyo kwaye ulahlekelwa iimpawu zayo. Ngaphezu koko, iingcali zithi, engenelela unalo LINGATSHA eliphezulu kwaye phemba umphezulu ezingqongileyo.
