Agasti 31st, 2021 China Standard Technology Division itolikwe umgangatho wesizwe weIiMathiriyeli eziRecycled kwiMveliso ye-NdFeB kunye nokuLungiswa.
1. Imvelaphi yokumisela umgangatho
I-Neodymium Iron boron imathiriyeli yemagnethi esisigxinaYikhompawundi ye-intermetallic eyenziwe ngezinto ezinqabileyo zomhlaba zesinyithi i-neodymium kunye nentsimbi. Ineempawu ezibalaseleyo zemagnethi kwaye yenye yezona zinto zibalulekileyo ezinqabileyo ezisebenzayo zomhlaba. Kwiminyaka yakutshanje, intsimi yesicelo se-NdFeB yezinto ezisisigxina zemagnethi iye yanda kakhulu. Yandisiwe ukusuka kwindawo yokuqala yokhuselo lwesizwe kunye necandelo lomkhosi wezomkhosi ezifana nenqwelomoya, i-aerospace, ukuhamba ngenqanawa kunye nezixhobo ukuya kuluhlu olubanzi lwemimandla ye-high-tech efana nezixhobo, amandla kunye nothutho, izixhobo zonyango, amandla e-elektroniki kunye nonxibelelwano.
Ngenxa yeemfuno zeemilo ezahlukeneyo ze-NdFeB izixhobo zemagnethi ezisisigxina kwiindawo ezahlukeneyo zesicelo, imveliso ye-NdFeB yezixhobo zemagnethi esisigxina e-China iqala ukuqhutyelwa kwizinto ezingenanto ezinemilo ehambelanayo, kwaye emva koko iqhutywe kwiimveliso ezigqityiweyo zeentlobo ezahlukeneyo ngokweemfuno zabasebenzisi. . Ngexesha lokuveliswa kunye nokucutshungulwa kwezixhobo zemagnethi ezisisigxina ze-Nd-Fe-B, inani elikhulu le-debris machining, izinto eziseleyo kunye ne-oil sludge debris ziya kuveliswa. Ukongeza, kuya kubakho izinto ezishiyekileyo eziluhlaza kwinkqubo yokugaya, ukucinezela, ukubumba kunye nokutshisa. Le nkunkuma zizixhobo eziphinda zisetyenziswe kwimveliso ye-Nd-Fe-B kunye nokusetyenzwa kwayo, ibalelwa malunga ne-20% ~ 50% yemathiriyeli ekrwada ye-Nd-Fe-B, ekwaziwa njengenkunkuma ye-Nd-Fe-B kushishino. . Ezo mathiriyeli ziphinda zisetyenzisiwe ziya kuqokelelwa ngokwahlelwa, uninzi lwazo ziya kuthengwa ngezityalo ezinqabileyo zokunyibilikiswa komhlaba kunye nokwahlulahlula, zihlaziywe kwaye zilungiswe zibe ziintsimbi zomhlaba ezinqabileyo, kwaye zisetyenziswe kwakhona kwimveliso ye-neodymium iron boron materials.
Ngophuhliso lweshishini le-Nd-Fe-B, iindidi ze-Nd-Fe-B ezisisigxina ze-magnet zityebile kwaye iinkcukacha ziyanda. Kukho iindidi ezinomxholo ophezulu we-cerium, i-holmium, i-terbium kunye ne-dysprosium. Umxholo we-cerium, i-holmium, i-terbium kunye ne-dysprosium kwimveliso ye-Nd-Fe-B ehambelanayo kunye nezixhobo zokuphinda zisetyenziswe kwakhona ziyanda, ezibangele utshintsho olukhulu kwisixa esipheleleyo somhlaba onqabileyo kunye nokubunjwa kwezinto ezinqabileyo zomhlaba kwi-Nd-Fe. -B imveliso kunye nokusetyenzwa kwezinto zokusetyenziswa kwakhona. Ngexesha elifanayo, ngokunyuka komthamo wokurhweba wezinto ezisetyenzisiweyo, kukho into eyenzeka kwizinto ezinqabileyo ezithatyathelwa indawo ezilungileyo kunye nobuxoki zidideke kunye nenyaniso kwinkqubo yokurhweba. Udidi lwezinto ezihlaziyiweyo kufuneka zichazwe ngakumbi, kwaye isampuli kunye neendlela zokulungiselela nazo kufuneka zicace ngakumbi ukulinganisa iimeko zokwamkelwa kunye nokunciphisa iingxabano zorhwebo. Umgangatho wokuqala we-GB / T 23588-2009 inkunkuma ye-Neodymium Iron Boron iye yapapashwa iminyaka engaphezu kweshumi, kwaye umxholo wayo wobugcisa awusafaneleki kwiimfuno zemarike yangoku.
2. Imixholo ephambili yomgangatho
Umgangatho uchaza umgaqo wokuhlelwa, iimfuno zokwakheka kweekhemikhali, iindlela zovavanyo, imithetho yokuhlola kunye nokupakishwa, ukumakisha, ukuthutha, ukugcinwa kunye nesatifikethi somgangatho wezinto ezisetyenzisiweyo kwakhona kwimveliso ye-NdFeB kunye nokusetyenzwa. Isebenza ekubuyiseni, ekusetyenzweni nasekurhwebeni kwenkunkuma eyahlukeneyo enokuphinda isetyenziswe (emva koku kubhekiselwa kuzo njengezinto ezisetyenzisiweyo) ezenziwe kwimveliso ye-NdFeB kunye nokulungiswa. Ngexesha lenkqubo yokulungiselela, ngophando olubanzi kunye neengxoxo zengcali amaxesha amaninzi, siye saphulaphula izimvo zamashishini emveliso yentsimbi ye-neodymium yentsimbi yaseTshayina, amashishini esicelo semveliso yentsimbi ye-neodymium kunye namashishini okwahlulwa komhlaba anqabileyo kwiminyaka yakutshanje, kwaye ichaza imixholo ephambili yobugcisa bemveliso. uhlaziyo lwalo mgangatho. Kwinkqubo yohlaziyo olusemgangathweni, ulwahlulo lwahlulahlulwe ngakumbi ngokwenkqubo yomthombo wezinto ezisetyenzisiweyo, imbonakalo kunye nokwakheka kweekhemikhali zezinto ezahlukeneyo ezisetyenzisiweyo zichazwe ngokweenkcukacha, kwaye isiseko sokuhlelwa zidweliswe ukunika isiseko sobuchwephesha sezinto eziphinda zisetyenziswe. intengiselwano.
Ukuhlelwa kwezinto ezisetyenzisiweyo, umgangatho uchaza iindidi ezintathu: umgubo owomileyo, udaka lwamagnetic kunye nezixhobo zebhloko. Kwinqanaba ngalinye, iimpawu zokubonakala kwezinto eziphathekayo zihlulwe ngokweenkqubo ezahlukeneyo zomthombo. Kwinkqubo yokurhweba ngezinto ezihlaziyiweyo, inani elipheleleyo lee-oxides zomhlaba ezinqabileyo kunye nomlinganiselo wento nganye yomhlaba onqabileyo zizona zibonakaliso eziphambili zexabiso. Ke ngoko, umgangatho udwelisa iitheyibhile zokuqulunqa isixa sisonke sezinto zomhlaba ezinqabileyo, umyinge wezinto zomhlaba ezinqabileyo kunye nesixa sezinto zomhlaba ezingezizo ezinqabileyo kwizinto eziphinda zisetyenziswe ngokulandelelana. Kwangaxeshanye, umgangatho unika izibonelelo ezineenkcukacha kwindlela yesampulu, izixhobo kunye nomlinganiselo wesampulu yezinto ezisetyenzisiweyo. Ngenxa yokuba izinto ezisetyenzisiweyo zihlala zingalingani, ukwenzela ukufumana iisampulu ezimele, lo mgangatho uchaza iinkcukacha zentonga yeplagi esetyenziswe kwisampuli, iimfuno zokukhethwa kwamanqaku esampuli kunye nendlela yokulungiselela isampuli.
3. Ukubaluleka kokuphunyezwa okusemgangathweni
Kukho isixa esikhulu semathiriyeli esetyenzisiweyo ukusuka kwimveliso ye-NdFeB kunye nokusetyenzwa kwe-China, eyimveliso yeempawu ze-NdFeB ezisisigxina kumzi-mveliso wemagnethi eTshayina. Ngokwembono yokuphinda isetyenziswe, imveliso ye-NdFeB kunye nokusetyenzwa kwemathiriyeli ehlaziyiweyo zizixhobo ezixabiseke kakhulu ezinokuphinda zisetyenziswe. Ukuba azihlaziywa, oko kuya kubangela inkcitho yezinto ezinqabileyo zomhlaba ezixabisekileyo kunye neengozi ezinkulu zokusingqongileyo. Ukuze kuncitshiswe umonakalo wokusingqongileyo obangelwa kukumbiwa komhlaba onqabileyo, i-China ibisoloko iphumeza ulawulo olungqongqo lwemveliso yomhlaba enqabileyo yokulawula ukumbiwa kwentsimbi ekrwada yomhlaba enqabileyo. Iimathiriyeli ezihlaziyiweyo zemveliso kunye nokulungiswa kwe-Nd-Fe-B ziye zaba zezona zinto zibalulekileyo zemathiriyeli ekrwada kumashishini anqabileyo okunyibilikisa nokwahlulahlula umhlaba e-China. Kuyo yonke imveliso kunye nonikezelo lwekhonkco lomhlaba onqabileyo waseTshayina ukuya kwi-NdFeB yezixhobo zemagnethi esisigxina, ukuphinda kusetyenziswe izinto ezinqabileyo zomhlaba kwanele kakhulu, kunye nesantya sokubuyisela esiphantse sibe yi-100%, ethintela ngokufanelekileyo inkcitho yezinto ezinqabileyo zomhlaba zexabiso eliphezulu kwaye yenza iChina Izixhobo zemagnethi ezisisigxina zeNdFeB zikhuphisana ngakumbi kwimarike yamazwe ngamazwe. Uhlaziyo kunye nokuphunyezwa komgangatho wesizwe weMveliso eRecycled Materials ye-Nd-Fe-B Production and Processing kulungele ukubeka emgangathweni ukuhlelwa, ukubuyiswa kunye norhwebo lwemathiriyeli esetyenzisiweyo ukuze imveliso ye-Nd-Fe-B iphinde isetyenziswe, kwaye inceda ekuhlaziyweni kwakhona kwe-Nd-Fe-B. ubuncwane bomhlaba obunqabileyo, ukunciphisa ukusetyenziswa kobutyebi kunye nokunciphisa iingozi zokusingqongileyo e-China. Ukuphunyezwa komgangatho kulindeleke ukuba kuzise izibonelelo ezilungileyo zoqoqosho kunye nexabiso lentlalo, kunye negalelo kuphuhliso oluzinzileyo lweshishini lomhlaba elinqabileyo laseTshayina Uphuhliso olunempilo!
