Akatambanudza NDFEB Magnet

Sintered NdFeB magnets a vari wakagadzirwa yakatsvuka zvinhu kuitwa yakarukutika muvira, kukandwa muvira Foroma uye dzaserera kuti fomu vara. The vara vari pulverized uye milled; madota ari ipapo sintered kupinda batana zvinogumbura. The ndeizvi zvino kupisa zvakaipa, akachekwa kuti chimiro, pamusoro zvakaipa uye magnetized.

Muna 2012, matani 50,000 pamusoro neodymium magnets a anobudiswa pamutemo gore negore China, uye matani 80,000 ari "kambani-ne-kambani" akavaka-up kuitwa 2013. China pave zvinopfuura 95% yenyika isingawanzowanikwi okunze, uye pave pamusoro 76% yenyika kwakazara kushoma-pasi magnets a.

Neodymium magnets a vari graded maererano kunonyanyisa simba chigadzirwa, chinotaura kuti rinobva nekubudisa goho muzana chikwata vhoriyamu. Yepamusoro tsika dzinoratidza magnets a kusimba uye siyana N35 kusvikira N52. Tsamba inotevera mugiredhi kunoratidza kunonyanyisa anodawo tembiricha (kazhinji Curie tembiricha), izvo siyana M (kusvika 100 ° C) kuna Eh (200 ° C).

Sintered Nd2Fe14B kunoita kuva nyore kuti ngura, kunyanya pamwe zviyo miganhu ine sintered magineti. Izvi mhando ngura kunogona kukonzera zvakakomba kudzikira, kusanganisira makariita ane magineti kuva upfu zviduku rinobva nezvimedu, kana spallingof imwe pemvura rukoko.
munjodzi iyi inotaurwa nezvayo dzakawanda yezvokutengeserana zvigadzirwa nokuwedzera rwokudzivirira unhani kudzivirira kukuvadzwa mumhepo. Nickel yakanamirwa pamifananidzo kana-layered maviri mhangura-nickel yakanamirwa pamifananidzo vari mureza nzira, kunyange zvazvo ra pamwe nedzimwe simbi, kana polymer uye lacquer anodzivirira coatings zvinogarawo kushandiswa.

Neodymium magnets a vakatsiva alnico uye ferrite magnets a mu vazhinji zviuru mafomu vemazuva ano apo simba magnets a zvechigarire zvinodiwa, nekuti kwavo kukuru simba kunoita kushandiswa zviduku, magnets a kupenya kuti kupiwa kushanda. Mienzaniso ndiwo:
Head actuators nokuti kombiyuta zvakaoma disks
Magnetic resonance kuri (MRI)
Mechanical e-mudzanga vachiridzira haizoshandisi
Locks nokuti mikova
Loudspeakers uye pamahedhifoni
Magnetic mabheyaringi uye okubatanidza
Electric Motors:
Cordless Ezvemutauro
Servomotors
Lifting uye compressor Motors
Synchronous Motors
Spindle uye and Motors
Electrical simba gozvo
Drive Motors nokuti chemasanganiswa uye motokari yemagetsi. The dzemagetsi Motors neimwe Toyota Prius zvinoda 1 kilogram (2.2 makirogiramu) kuti neodymium.
Actuators
Electric emagetsi nokuti mhepo turbines (chete vaya zvachose magineti excitation)
Direct-fambisa mhepo turbines zvinoda c. makirogiramu 600 PM zvinhu pa megawatt
Turbines vachishandisa rachulis zvinoda zvishoma PM zvinhu pa megawatt
