Agasti 31st, 2021 China Standard Technology Division yahumusha izinga likazwelonke lokuthiIzinto Ezisetshenziswa Kabusha Zokukhiqiza Nokucubungula kwe-NdFeB.
1. Ingemuva lesethingi elijwayelekile
I-Neodymium Iron boron unomphela uzibutheiyinhlanganisela ye-intermetallic eyakhiwe yizakhi zensimbi zomhlaba ezingavamile i-neodymium nensimbi.Inezici ezinhle kakhulu zikazibuthe futhi ingenye yezinto ezibalulekile ezingavamile ezisebenzayo zomhlaba.Eminyakeni yamuva nje, inkambu yokusetshenziswa kwezinto zikazibuthe ze-NdFeB isiye yaba banzi.Iye yanda isuka emikhakheni yokuqala yezokuvikela kazwelonke kanye nemboni yezempi efana nezindiza, i-aerospace, ukuzulazula nezikhali kuya emikhakheni ebanzi yobuchwepheshe obuphezulu bomphakathi njengamathuluzi, amandla nezokuthutha, amathuluzi ezokwelapha, amandla kagesi kanye nokuxhumana.
Ngenxa yezidingo ezihlukene zomumo wezinto zikazibuthe ezihlala unomphela ze-NdFeB emikhakheni ehlukene yohlelo lokusebenza, ukukhiqizwa kwezinto zikazibuthe ze-NdFeB e-China kuqala kucutshungulwa zibe izinto ezingenalutho ezinomumo ongaguquki, bese zicutshungulwa zibe imikhiqizo ephelile yezinhlobo ezahlukene ngokuvumelana nezidingo zabasebenzisi. .Ngesikhathi sokukhiqizwa nokucutshungulwa kwezinto zikazibuthe ezihlala njalo ze-Nd-Fe-B, kuzokhiqizwa inani elikhulu lemfucumfucu yomshini, izinto ezisele kanye nemfucumfucu kawoyela ye-sludge.Ukwengeza, kuzoba nensalela yezinto zokusetshenziswa ohlelweni lokugaya, ukucindezela, ukwakha kanye nokugazinga.Lezi zibi ziyizinto ezigaywe kabusha zokukhiqiza nokucubungula i-Nd-Fe-B, ezibalelwa ku-20% ~ 50% wezinto ezingavuthiwe ze-Nd-Fe-B, eyaziwa nangokuthi i-Nd-Fe-B imfucuza embonini. .Izinto ezinjalo ezigaywe kabusha zizoqoqwa ngokwezigaba, eziningi zazo ezizothengwa izitshalo zokuncibilikisa nokuhlukanisa umhlaba ezingavamile, zigaywe kabusha futhi zigaywe zibe izinsimbi zomhlaba ezingavamile, bese zisetshenziswa futhi ekukhiqizeni izinto ze-iron boron ye-neodymium.
Ngokuthuthuka kwemboni ye-Nd-Fe-B, izigaba zezinto zikazibuthe ze-Nd-Fe-B zicebile futhi imininingwane iyanda.Kunezinhlobonhlobo ezinokuqukethwe okuphezulu kwe-cerium, i-holmium, i-terbium ne-dysprosium.Okuqukethwe kwe-cerium, i-holmium, i-terbium ne-dysprosium ekukhiqizeni okuhambisanayo kwe-Nd-Fe-B nokucubungula izinto ezigaywa kabusha nakho kuyakhula, okuholela ekushintsheni okukhulu enanini eliphelele lomhlaba ongavamile kanye nokwakheka kwezakhi zomhlaba eziyivelakancane ku-Nd-Fe. -B ukukhiqizwa nokucubungula izinto zokugaywa kabusha.Ngesikhathi esifanayo, ngokwanda komthamo wokuhweba wezinto ezigaywe kabusha, kukhona isenzakalo sezinto ezingenalutho ezithathelwa indawo ezinhle nezingamanga ezididaniswa neziyiqiniso ohlelweni lokuhweba.Isigaba sezinto ezigaywe kabusha sidinga ukucaciswa okwengeziwe, futhi izindlela zokusampula nezindlela zokulungiselela nazo kudingeka zicace ukuze kumiswe izimo zokwamukela nokunciphisa izingxabano zohwebo.Imfucuza ye-GB / T 23588-2009 ye-Neodymium Iron Boron yokuqala ishicilelwe iminyaka engaphezu kweyishumi, futhi okuqukethwe kwayo kwezobuchwepheshe akusafanele izidingo zemakethe yamanje.
2. Okuqukethwe okuyinhloko kwezinga
Izinga licacisa umgomo wokuhlukaniswa, izidingo zokwakheka kwamakhemikhali, izindlela zokuhlola, imithetho yokuhlola nokupakishwa, ukumakwa, ukuthutha, ukugcinwa kanye nesitifiketi sekhwalithi sezinto ezigaywe kabusha zokukhiqizwa nokucubungula kwe-NdFeB.Isebenza ekubuyiseni, ekucubungulweni nasekuhwebeni kwemfucuza ehlukahlukene egaywa kabusha (ngemuva kwalokhu ebizwa ngokuthi izinto ezigaywe kabusha) ezikhiqizwe nasekucutshungulweni kwe-NdFeB.Phakathi nenqubo yokulungiselela, ngophenyo olunzulu kanye nengxoxo yochwepheshe izikhathi eziningi, silalele imibono yamabhizinisi aseShayina okukhiqiza i-boron yensimbi ye-neodymium, amabhizinisi esicelo somkhiqizo we-neodymium iron boron kanye namabhizinisi angavamile okuhlukanisa umhlaba eminyakeni yamuva, futhi sachaza okuqukethwe okubalulekile kwezobuchwepheshe ukubuyekezwa kwaleli zinga.Enqubweni yokubuyekezwa okujwayelekile, ukuhlukaniswa kuphinde kuhlukaniswe ngokuningiliziwe ngokuya ngenqubo yomthombo wezinto ezigaywe kabusha, ukubukeka nokwakheka kwamakhemikhali ezinto ezahlukahlukene ezigaywe kabusha kuchazwa ngokuningiliziwe, futhi isisekelo sokuhlukaniswa sikleliswe ukunikeza isisekelo sobuchwepheshe sezinto ezigaywe kabusha. ukuthengiselana.
Ukuze kuhlukaniswe izinto ezigaywe kabusha, indinganiso ichaza izigaba ezintathu: impushana eyomile, udaka olukazibuthe nezinto zokuvimba.Esigabeni ngasinye, izici zokubukeka zezinto zihlukaniswa ngokwezinqubo ezihlukene zomthombo.Enqubweni yokuhweba yezinto ezigaywe kabusha, inani eliphelele lama-oxides omhlaba angavamile kanye nengxenye yento ngayinye yomhlaba eyivelakancane kuyizinkomba zentengo eziyinhloko.Ngakho-ke, indinganiso ibala amathebula okuqamba yenani eliphelele lezinto zomhlaba ezingavamile, ingxenye yezakhi zomhlaba ezingavamile kanye nenani lezinto zomhlaba ezingandile ezintweni ezigaywe kabusha ngokulandelana kwazo.Ngesikhathi esifanayo, izinga linikeza izinhlinzeko ezinemininingwane mayelana nendlela yesampula, amathuluzi kanye nengxenye yesampula yezinto ezigaywe kabusha.Ngenxa yokuthi izinto ezigaywe kabusha ngokuvamile azilingani, ukuze kutholwe amasampula amele, leli zinga licacisa imininingwane ye-plug rod esetshenziswa kusampula, izidingo zokukhethwa kwamasampula kanye nendlela yokulungiselela isampula.
3. Ukubaluleka kokuqaliswa okujwayelekile
Kunenani elikhulu lezinto ezisetshenziswe kabusha ezivela ekukhiqizeni nasekucutshungulweni kwe-NdFeB e-China, okuwumkhiqizo wesici semboni ye-NdFeB ehlala unomphela kazibuthe eChina.Ngokombono wokugaywa kabusha kwezinsiza, ukukhiqizwa kwe-NdFeB nokucubungula izinto ezigaywe kabusha kuyizinsiza ezivuselelekayo ezibaluleke kakhulu.Uma zingaphinde zisetshenziswe kabusha, kuzodala ukumoshwa kwemithombo yomhlaba ebalulekile eyivelakancane kanye nezingozi ezinkulu zemvelo.Ukuze kuncishiswe ukulimala kwemvelo okubangelwa izimayini zomhlaba eziyivelakancane, i-China ibilokhu isebenzisa ukulawulwa okuqinile kwesilinganiso sokukhiqizwa komhlaba okungavamile ukuze kulawuleke ukumbiwa kwensimbi eyivelakancane yomhlaba.Izinto ezigaywe kabusha zokukhiqiza nokucubungula kwe-Nd-Fe-B seziphenduke enye yezinto ezibalulekile zokusetshenziswa kwebhizinisi elingavamile lokuncibilikisa nokuhlukanisa umhlaba e-China.Kuwo wonke uchungechunge lokukhiqizwa nokuhlinzekwa komhlaba ongavamile waseChina kuya ezintweni zikazibuthe ezihlala unomphela ze-NdFeB, ukugaywa kabusha kwezinto ezingavamile zomhlaba kwanele kakhulu, ngezinga lokutakula elicishe libe yi-100%, eligwema ngempumelelo ukuchithwa kwezakhi zomhlaba eziyivelakancane ezinenani eliphezulu futhi lenze iChina NdFeB unomphela uzibuthe materials ukuncintisana ngaphezulu emakethe international.Ukubuyekezwa kanye nokuqaliswa kwezinga likazwelonke le-Recycled Materials for Nd-Fe-B Production and Processing kulungele ukulinganisa, ukubuyiselwa kanye nokuhwebelana kwezinto ezigaywe kabusha zokukhiqiza nokucubungula i-Nd-Fe-B, futhi kulungele ukugaywa kabusha kwe-Nd-Fe-B. izinsiza zomhlaba ezingavamile, ukunciphisa ukusetshenziswa kwezinsiza kanye nokunciphisa izingozi zemvelo e-China.Ukuqaliswa kwaleli zinga kulindeleke ukuthi kulethe izinzuzo ezinhle kwezomnotho kanye nokubaluleka kwezenhlalo, futhi kube neqhaza ekuthuthukisweni okusimeme kwemboni yomhlaba engavamile yaseChina Ukuthuthukiswa okunempilo!
