Gukwirakwiza ubumenyi kuri NdFeb isi idasanzwe ya rukuruzi ihoraho

Ingaruka yifu yahinduwe inyongeramusaruro mubikorwa bya NdFeb ubusa.

Kugirango tubyare umusaruro-mwinshi NdFebrukuruzi ihorahoibikoresho, tugomba kugenzura ubunini bwimyuka yo mu kirere isya ifu ya magnetiki yifu, kugirango ubunini bwa porojeri ya magneti muri 2.5 ~ 5μm bingana na 95%.Xinfeng Magnet yasanze inzira ishobora kunozwa cyane hiyongereyeho ifu yihariye yo guhindura ifu mugikorwa cyo gusya ikirere.

Ifu yahinduwe inyongeramusaruro igomba kugira imikorere ihuriweho, aribyo: (1) ibikorwa byo kurwanya okiside;(2) Kunoza imikorere ya powder fluidity;(3) Irinde ifu yaka, aribyo gutwika imikorere.Ingano yinyongeramusaruro igera kuri 0.035% ~ 0,05% (agace kinshi) yifu ya magneti, ubusanzwe ikongerwaho icyarimwe hamwe nifu ya rukuruzi aho uruganda rugaburira.

Inyongeramusaruro ni ibice byinshi bigize ibinyabuzima, hamwe nitsinda rya lipofilique, aribyo iminyururu ya hydrocarubone, irimo amatsinda mato ya polar, nkamatsinda ya lipide, kuburyo urunigi rwa hydrocarubone rufite uburebure bukwiye.Ifu ya magnetique ibice byinshi bigongana kandi bigakoraho ninyongeramusaruro mugikorwa cyo gusya ikirere, kuburyo ubuso bwa buri gice cyashizwe hamwe nigice cya firime yongeramo uburebure bwa 5 ~ 8nm.Ifite inshingano zikurikira: (1) Irinde ibice by'ifu guhura n'umwuka, bigira uruhare rwo kurwanya okiside;.(3) Kongera umuvuduko no kugenda kwifu ya poro kandi ukagira uruhare rwamavuta;(4) Ni ingirakamaro ku cyerekezo cy'ifu ya poweri mu murima wa magneti, ushobora kunoza icyerekezo;BR irashobora kwiyongera kuri 0.02-0.04 T, naho ingufu za rukuruzi (BH) m zishobora kwiyongera uko bikwiye.Twabibutsa ko ubushyuhe buhindagurika bwiyi nyongeramusaruro ari 350 ℃.Ubushyuhe bwo gucumura bugomba gufatwa kuri 400-420 ℃ mugihe runaka, kugirango inyongeramusaruro zisohore muri magneti, kugirango bitaba karburize.

Ibisabwa nkenerwa kugirango ubyare umusaruro mwiza wohanze NdFeb rukuruzi.

Kugirango ubone icyerekezo cyiza cya magnesi, magnet ya Xinfeng yaje kugera kumusozo nyuma yimyaka yubushakashatsi hamwe nibitekerezo bihuriweho kumikoreshereze yabakiriya kumasoko ko ari ngombwa gukora ifu ya magnetiki NdFeb yacumuye kugirango yuzuze ibisabwa bikurikira kugirango ibicuruzwa byujuje ubuziranenge bishoboke kuremwa, kandi ibikoresho byimiti gusa nibyiza, imiti izaba nziza.. menya neza ko ibice byose ari kristu imwe.(2) Ibice by'ifu bifatanye cyangwa bigereranijwe.(3) Inenge ya kristu yibice byifu igomba kuba bike bishoboka...Kubwibyo, gahunda yo gutegura ifu igomba gukorwa muburyo bwiza bwo kurinda gazi ya inert cyangwa mu kirere, kugirango hirindwe ifu ya magneti ihura na ogisijeni cyangwa umwuka w’ubushuhe.Ibintu bitanu byavuzwe haruguru birakenewe mugukora ubuziranenge bwa NdFeb buhoraho, kubura buri kimwe ntabwo byifuzwa, bisa nkibyoroshye, mubyukuri buriwese ashobora gukora neza ntabwo byoroshye, magnet ya Xinfeng yiteguye gukorana nabantu bingeri zose kugeza kora ibicuruzwa byiza cyane, kandi uharanire guha abakiriya serivisi nziza.

Intambwe nshya ya Xinfeng Magnet mugutezimbere imbaraga za magnet ya NdFeb yacumuye.

Guhatira ni kimwe mu bintu byingenzi bya tekinike ya rukuruzi ihoraho.Kongera agahato birashobora kongera ingufu za magneti nini yingufu za rukuruzi, kunoza uburyo bwo kurwanya demagnetisation ya rukuruzi ihoraho ikoreshwa, kandi igatezimbere ituze.Kugeza ubu, mugutegura ternary yuzuye yacumuye NdFeb ya magneti ahoraho, imiterere ya magnetiki tekinike nindangagaciro za teoretiki, hamwe na remanence BR imaze kugera kuri 96.27% byagaciro kayo, naho ibicuruzwa binini bya rukuruzi BH bigeze kuri 91.5% byamahame yayo. agaciro.Nyamara, imbaraga zagahato zageze kuri 12% gusa byagaciro kayo.Nibishoboka byinshi kunoza imbaraga zagahato, haracyari kwiyongera gukomeye mumwanya.Magnet ya Xinfeng yagiye ikora cyane kubwibi.

Ubwa mbere, imbaraga za rukuruzi zirashobora kunozwa neza mugusimbuza Nd igice cya Dy na Tb.Nyamara, mubutaka budasanzwe bwubutaka bwicyuma, Dy na Tb biri hasi mubirimo kandi bihenze, kandi Dy na Tb birashobora kongerwaho gusa mubunini.Icya kabiri, kongeramo ibintu bimwe na bimwe byicyuma nka AL, Nb, Ga, Ti, Zr, Mo, nibindi, mugihe ibyo bintu byinjiye muri kristu, microstructure hamwe nibikorwa bigenda bigaragara ko byateye imbere, kandi bikongerera imbaraga za rukuruzi.Icya gatatu, imbaraga za rukuruzi zirashobora kunozwa neza wongeyeho ibintu no gukoresha ubushyuhe buke bwo gucumura cyangwa uburyo bubiri bwo kugabanya kugabanya ingano ya kristu.

Ibikurikira, magnet ya Xinfeng izakomeza gukora cyane kugirango iteze imbere ingufu nini za rukuruzi za NdFeb zacumuye, kandi zihore zitanga ibicuruzwa byiza kubakiriya.
