Sintered NdFeB magnesi zihoraho, nkimwe mubintu byingenzi bigamije guteza imbere ikoranabuhanga rya none niterambere ryimibereho, bikoreshwa cyane mubice bikurikira: disiki ikomeye ya mudasobwa, amashusho ya magnetiki resonance yerekana amashusho, ibinyabiziga byamashanyarazi, kubyara ingufu z'umuyaga, moteri ya rukuruzi ihoraho, ibikoresho bya elegitoroniki. .
Mu myaka 30 ishize, inganda zihoraho za magneti ku isi zateye imbere kuva mu 1985, igihe inganda zatangiraga kuba inganda mu Buyapani, Ubushinwa, Uburayi na Amerika, kandi imitungo ya rukuruzi yashyizeho amateka mashya kandi yongera umubare ubwoko bwibintu hamwe n amanota. Hamwe no kwagura isoko, abayikora nabo bariyongera, kandi abakiriya benshi byanze bikunze bafatwa nuru rujijo, nigute dushobora kumenya ibyiza byibicuruzwa? Inzira yuzuye yo guca imanza: icya mbere, imikorere ya magneti; kabiri, ubunini bwa magneti; icya gatatu, gutwikira magnet.
Ubwa mbere, garanti yimikorere ya magneti iva mugucunga inzira yumusaruro wibikoresho fatizo
1 、 Ukurikije ibisabwa ninganda zikora inganda zo mu rwego rwo hejuru cyangwa urwego rwo hagati cyangwa urwego rwo hasi rwacumuye NdFeB, ibikoresho fatizo bikurikije amahame yigihugu yo kugura ibikoresho bibisi.
2 process Ibikorwa byiterambere byateye imbere byerekana neza imikorere ya magneti. Kugeza ubu, tekinoroji igezweho ni tekinoroji ya Ingot Casting (SC), tekinoroji ya Hydrogen Crushing (HD) hamwe na tekinoroji ya Airflow Mill (JM).
Ubushobozi buke bwa vacuum induction itanura (10kg, 25kg, 50kg) bwasimbuwe nubushobozi bunini (100kg, 200kg, 600kg, 800kg) itanura rya vacuum, tekinoroji ya SC (StripCasting) yagiye isimbuza buhoro buhoro ingoti nini (ingots zifite umubyimba urenze 20- 40mm mu cyerekezo cyo gukonjesha), HD (Hydrogen Crushing) ikoranabuhanga hamwe ninganda zitwara gaze (JM) aho kuba umusaya, urusyo rwa disiki, urusyo. .
3 、 Ku cyerekezo cya magnetiki, Ubushinwa nicyo gihugu cyonyine ku isi cyifashisha imashini ebyiri, hamwe n’umuvuduko muto uhagaritse icyerekezo ugana icyerekezo hamwe na quasi-isostatike iheruka, kikaba ari kimwe mu bintu by'ingenzi biranga Ubushinwa bwacumuye Inganda.
Icya kabiri, garanti yubunini bwa magneti biterwa nimbaraga zo gutunganya uruganda
Porogaramu nyayo ya NdFeB ya magneti ahoraho ifite imiterere itandukanye, nkuruziga, silindrike, silindrike (hamwe nu mwobo w'imbere); kare, kare, kare; tile, umufana, trapezoid, polygon nuburyo butandukanye budasanzwe.
Buri shusho ya magnesi zihoraho zifite ubunini butandukanye, kandi inzira yo kubyara iragoye gushingwa muburyo bumwe. Ibikorwa rusange byumusaruro ni: Bwana asohora ibinini binini (binini binini), nyuma yo gucumura no gutondeka ubushyuhe, hanyuma akoresheje gutunganya imashini (harimo gukata, gukubita) no gusya, gutunganya isahani (gutwikira), hanyuma imikorere ya magneti, ubwiza bwubuso na ibipimo byukuri, hanyuma magnetisiyonike, gupakira hamwe nuruganda.
1, gutunganya imashini bigabanijwemo ibyiciro bitatu: (1) gutunganya gutema: gukata silindrike, magneti zingana na kare mu buryo buzengurutse, buringaniye, hamwe na shobuja cyangwa ubundi buryo bugoye bwa magneti, (3) gutunganya gukubita: gutunganya uruziga, rukuruzi ya kare ya magneti mumashanyarazi ya silindrike cyangwa ifite kare. Uburyo bwo gutunganya ni: gusya no gutema, gutunganya EDM no gutunganya laser.
2 、 Ubuso bwa NdFeB icumura ibice bya magneti bihoraho mubisanzwe bisaba ubworoherane nibisobanuro bimwe na bimwe, kandi ubuso bwa magneti bwatanzwe mubusa bukenera gusya hejuru. Uburyo busanzwe bwo gusya kuri kare ya NdFeB ya magneti ihoraho ni ugusya indege, gusya kabiri, gusya imbere, gusya hanze, n'ibindi. ni Byakoreshejwe.
Magnet yujuje ibyangombwa ntabwo ikeneye gusa kubahiriza imikorere, ariko kandi kugenzura kwihanganira ibipimo bigira ingaruka kubikorwa byayo. Ingwate yingirakamaro iterwa nimbaraga zo gutunganya uruganda. Ibikoresho byo gutunganya bihora bivugururwa hamwe nubukungu bukenewe nisoko, kandi icyerekezo cyibikoresho bikora neza hamwe n’inganda zikoresha inganda ntabwo ari ugukemura gusa abakiriya biyongera kubicuruzwa neza, ahubwo ni no kuzigama abakozi nigiciro, bigatuma irushanwa muri isoko.
Na none, ubwiza bwa plaque ya magneti bugena neza ubuzima bwibicuruzwa
Mubigeragezo, magnet ya 1cm3 yacumuye NdFeB izangirika na okiside niba isigaye mu kirere kuri 150 ℃ muminsi 51. Mubisubizo bidakomeye bya acide, birashoboka cyane ko byangirika. Kugirango ugire NdFeB magnesi zihoraho, birasabwa kugira ubuzima bwa serivisi bwimyaka 20-30.
Igomba kuvurwa hakoreshejwe uburyo bwo kurwanya ruswa kugira ngo irwanye ruswa ya rukuruzi n'ibitangazamakuru byangiza. Kugeza ubu, magnet ya NdFeB yacumuye muri rusange yometseho icyuma, amashanyarazi + amasahani y’imiti, amashanyarazi ya elegitoronike hamwe n’ubuvuzi bwa fosifate kugira ngo magneti adashobora kwangirika.
1, muri rusange galvanised, nikel + umuringa + isahani ya nikel, nikel + umuringa + imiti ya nikel isahani yuburyo butatu, ibindi bisabwa byo gusiga ibyuma, mubisanzwe bikoreshwa nyuma yo gushiraho nikel hanyuma nibindi byuma.
2, mubihe bimwe bidasanzwe bizanakoresha fosifatiya: (1) mubicuruzwa bya magneti ya NdFeB kubera ibicuruzwa, kubika umwanya ni birebire kandi ntibisobanutse mugihe uburyo bwakurikiyeho bwo kuvura hejuru, gukoresha fosifati yoroshye kandi yoroshye; . Inzira ya fosifati irashobora kunoza ubuso bwubushobozi bwa magneti bwo gucengera.
3, amashanyarazi ya electrophoreque yabaye imwe muburyo bukoreshwa muburyo bwo kuvura ruswa. Kuberako idafite aho ihurira gusa nubuso bwa magneti gusa, ariko kandi ifite imbaraga zo kurwanya ruswa yumunyu, aside, alkali, nibindi, birwanya ruswa. Nyamara, kurwanya ubukonje nubushyuhe ni bibi ugereranije no gutera spray.
Abakiriya barashobora guhitamo igifuniko bakurikije ibicuruzwa byabo bisabwa. Hamwe no kwagura ikibuga gisaba moteri, abakiriya bafite ibisabwa byinshi kugirango barwanye ruswa ya NdFeB. Ikizamini cya HAST (nanone cyitwa test ya PCT) ni ukugerageza kwangirika kwangirika kwa magnetiki ya NdFeB yanduye munsi yubushyuhe nubushyuhe bwinshi.
Nigute umukiriya ashobora kumenya niba isahani yujuje ibisabwa cyangwa itujuje? Ikigamijwe cyo gupima umunyu nugukora ikizamini cyihuse cyo kurwanya ruswa kuri magneti NdFeB yacumuye ubuso bwayo bwakorewe hamwe na anti-ruswa. Ikizamini kirangiye, icyitegererezo gikurwa mucyumba cy’ibizamini, cyumye, kandi kigenzurwa n'amaso cyangwa ikirahure kinini kugira ngo harebwe niba hari ibibara hejuru y’icyitegererezo, ubunini bw'ahantu agasanduku k'ibara ryahindutse.
