Kutanthauzira kwa National Standard of Recycled Materials kwa NdFeB Production and Processing

Ogasiti 31^st, 2021 China Standard Technology Division anatanthauzira mulingo wadziko lonse waZobwezerezedwanso kwa NdFeB Kupanga ndi Kukonza.

1. Standard zoikamo maziko

Neodymium Iron boron maginito okhazikikandi intermetallic pawiri wopangidwa ndi osowa lapansi zitsulo zinthu neodymium ndi chitsulo.Ili ndi maginito abwino kwambiri ndipo ndi imodzi mwazinthu zofunikira kwambiri padziko lapansi.M'zaka zaposachedwapa, ntchito munda wa NdFeB okhazikika maginito zipangizo wakhala kwambiri ndi zambiri.Yakula kuchokera kumadera oyambirira a chitetezo cha dziko ndi makampani ankhondo monga ndege, ndege, kuyenda ndi zida kupita kuzinthu zambiri zamakono zamakono monga zida, mphamvu ndi kayendedwe, zipangizo zamankhwala, mphamvu zamagetsi ndi kulankhulana.

Chifukwa osiyana mawonekedwe amafuna NdFeB okhazikika maginito zipangizo m'minda ntchito zosiyanasiyana, kupanga NdFeB okhazikika maginito zipangizo ku China choyamba kukonzedwa mu zipangizo opanda kanthu ndi mawonekedwe zogwirizana, ndiyeno kukonzedwa mu zomalizidwa mankhwala a mitundu yosiyanasiyana malinga ndi zosowa za owerenga. .Pakupanga ndi kukonza zida za maginito za Nd-Fe-B, zinyalala zambiri zamakina, zida zotsalira ndi zinyalala zamafuta zidzapangidwa.Kuphatikiza apo, padzakhala zotsalira zopangira pogaya, kukanikiza, kupanga ndi kukuwotcha.Zinyalala izi ndi zipangizo zobwezerezedwanso kwa Nd-Fe-B kupanga ndi processing, mlandu pafupifupi 20% ~ 50% ya zopangira Nd-Fe-B, amenenso amadziwika kuti Nd-Fe-B zinyalala makampani. .Zida zobwezerezedwanso zoterezi zidzasonkhanitsidwa mwamagulu, zomwe zambiri zidzagulidwa ndi zomera zosawerengeka zosungunula ndi zolekanitsa, zokonzedwanso ndi kusinthidwa kukhala zitsulo zapadziko lapansi, ndikugwiritsidwanso ntchito popanga zida za neodymium iron boron.

Ndi chitukuko cha makampani Nd-Fe-B, magulu Nd-Fe-B okhazikika maginito zipangizo ndi olemera ndipo specifications kukula.Pali mitundu yokhala ndi cerium, holmium, terbium ndi dysprosium.Zomwe zili mu cerium, holmium, terbium ndi dysprosium zomwe zikugwirizana ndi Nd-Fe-B kupanga ndi kukonzanso zipangizo zobwezeretsanso zikuwonjezeka, zomwe zimabweretsa kusintha kwakukulu kwa chiwerengero cha dziko lapansi chosowa komanso mapangidwe a zinthu zapadziko lapansi mu Nd-Fe. -B kupanga ndi kukonza zinthu zobwezeretsanso.Panthawi imodzimodziyo, ndi kuwonjezeka kwa malonda a malonda a zipangizo zobwezerezedwanso, pali chodabwitsa cha zinthu zopanda pake zomwe zimasinthidwa ndi zabwino ndi zabodza zomwe zikusokonezedwa ndi zowona pakuchita malonda.Gulu la zida zobwezerezedwanso liyenera kufotokozedwa mwatsatanetsatane, ndipo njira zotsatsira ndi zokonzekera ziyeneranso kumveka bwino kuti zikhazikitse mikhalidwe yovomerezeka ndikuchepetsa mikangano yamalonda.Zowonongeka zoyambirira za GB / T 23588-2009 Neodymium Iron Boron zasindikizidwa kwa zaka zopitirira khumi, ndipo zomwe zili mu luso lake sizilinso zoyenera pa zosowa za msika wamakono.

2. Nkhani zazikulu za muyezo

Muyezowu umatchula mfundo zamagulu, zofunikira za mankhwala, njira zoyesera, malamulo oyendera ndi kuyika, kulemba chizindikiro, mayendedwe, kusungirako ndi satifiketi yamtundu wazinthu zobwezerezedwanso pakupanga ndi kukonza kwa NdFeB.Imagwiranso ntchito pakubwezeretsa, kukonza ndi kugulitsa zinyalala zosiyanasiyana zobwezerezedwanso (zotchedwanso zosinthidwa) zomwe zimapangidwa mukupanga ndi kukonza kwa NdFeB.Pa nthawi yokonzekera, kupyolera mu kufufuza kwakukulu ndi kukambirana kwa akatswiri kwa nthawi zambiri, tinamvetsera maganizo a mabizinesi akupanga chitsulo cha neodymium ku China, mabizinesi ogwiritsira ntchito chitsulo cha neodymium chitsulo ndi mabizinesi osowa padziko lapansi m'zaka zaposachedwa, ndikulongosola zofunikira zamakono za kusinthidwa kwa muyezo uwu.Pakukonzanso kokhazikika, gululi limagawidwanso mwatsatanetsatane malinga ndi momwe zida zobwezerezedwanso zimayambira, mawonekedwe ndi mawonekedwe azinthu zobwezerezedwanso zimafotokozedwa mwatsatanetsatane, ndipo maziko amagawo adalembedwa kuti apereke maziko aukadaulo pazinthu zobwezerezedwanso. kugulitsa.

Pakugawa zinthu zobwezerezedwanso, muyezo umatanthawuza magawo atatu: ufa wowuma, matope a maginito ndi zida zotchinga.Pagulu lililonse, mawonekedwe azinthu amagawidwa motsatira njira zosiyanasiyana zoyambira.Pochita malonda azinthu zobwezerezedwanso, kuchuluka kwa ma oxides osowa padziko lapansi ndi gawo la chinthu chilichonse chosowa padziko lapansi ndizozizindikiro zazikulu zamitengo.Chifukwa chake, mulingo umalemba mndandanda wazinthu zonse zapadziko lapansi, kuchuluka kwa zinthu zapadziko lapansi zomwe sizipezeka kawirikawiri komanso kuchuluka kwa zinthu zapadziko lapansi zomwe zidabwezedwanso motsatana.Nthawi yomweyo, muyezo umapereka mwatsatanetsatane njira yopangira sampuli, zida ndi gawo lachitsanzo la zinthu zobwezerezedwanso.Chifukwa zinthu zobwezerezedwanso nthawi zambiri zimakhala zosagwirizana, kuti mupeze zitsanzo zoyimilira, mulingo uwu umanena za ndodo ya pulagi yomwe imagwiritsidwa ntchito poyesa, zomwe zimafunikira pakusankha zitsanzo ndi njira yokonzekera zitsanzo.

3. Kufunika kwa kukhazikitsidwa koyenera

Pali kuchuluka kwa zipangizo zobwezerezedwanso ku NdFeB kupanga ndi processing ku China, amene ndi khalidwe mankhwala a NdFeB okhazikika maginito makampani chuma China.Kutengera kukonzanso kwazinthu, kupanga ndi kukonza zinthu zobwezerezedwanso ndi NdFeB ndizofunika kwambiri zongowonjezedwanso.Ngati sizidzagwiritsidwanso ntchito, zidzawononga zinthu zamtengo wapatali zapadziko lapansi komanso zoopsa zazikulu zachilengedwe.Pofuna kuchepetsa kuwonongeka kwa chilengedwe chifukwa cha migodi yachilendo, dziko la China nthawi zonse lakhazikitsa malamulo okhwima okhudza kupanga dziko lapansi kuti athetse migodi ya ore yachilendo.Zida zobwezerezedwanso zopangira ndi kukonza za Nd-Fe-B zakhala chimodzi mwazinthu zofunika kwambiri zamabizinesi osowa kusungunula ndi kulekanitsa nthaka ku China.Ponseponse kupanga ndi kupereka unyolo wa China osowa dziko lapansi kwa NdFeB okhazikika maginito zipangizo, yobwezeretsanso zinthu osowa dziko ndi okwanira kwambiri, ndi mlingo kuchira pafupifupi 100%, amene bwino amapewa zinyalala zamtengo wapatali osowa dziko lapansi ndi kupanga China a NdFeB okhazikika maginito zipangizo mpikisano kwambiri msika mayiko.Kuwunikiridwa ndi kukhazikitsidwa kwa mulingo wapadziko lonse wa Recycled Materials for Nd-Fe-B Production and Processing kumathandizira kuyikanso magawo, kubwezeretsa ndi kugulitsa zinthu zobwezerezedwanso kuti apange ndi kukonza za Nd-Fe-B, ndipo zimathandizira kukonzanso kwa zinthu zapadziko lapansi zomwe sizipezeka, kuchepetsa kugwiritsidwa ntchito kwa zinthu komanso kuchepetsa kuopsa kwa chilengedwe ku China.Kukhazikitsidwa kwa muyezowu kukuyembekezeka kubweretsa zabwino zachuma komanso phindu lazachuma, ndikuthandizira chitukuko chokhazikika chamakampani osowa padziko lapansi aku China Chitukuko chathanzi!
