Tha iad beaga ach cumhachdach, agus tha iad an l\u00e0thair ann an \u00e0ireamh mh\u00f2r de dh\u2019 innealan a chleachdas sinn gach latha.<\/p>\n
D\u00e8 tha neomagnet air a dh\u00e8anamh de?<\/h2>\n
Chan eil a h-uile magnet air an d\u00e8anamh co-ionann\u2014tha cuid air an d\u00e8anamh le eileamaidean talmhainn tearc airson coileanadh \u00e0rd-\u00ecre.<\/p>\n
Tha neomagnets air an d\u00e8anamh suas de neodymium (Nd), iarann (Fe), agus boron (B), a\u2019 cruthachadh structar Nd\u2082Fe\u2081\u2084B a bheir dhaibh neart magnetach air leth.<\/strong><\/p>\n Tha d\u00e0 phr\u00ecomh she\u00f2rsa de magnetan neodymium:<\/p>\n Tha an structar criostail aca tetragonal, a leigeas le magnetachadh l\u00e0idir ann an sti\u00f9ireadh st\u00e8idhichte. Tha an sti\u00f9ireadh seo cudromach ann an tagraidhean a dh\u2019 fheumas toradh magnetach earbsach agus cuimsichte.<\/p>\n Tha mi air obair le luchd-ceannach a\u2019 taghadh eadar magnetan ceangailte agus sintered airson mothachairean f\u00e8in-ghluasadach. Thug magnetan sintered freagairt nas fhe\u00e0rr dhaibh, fhad \u2018s a chuidich roghainnean ceangailte nuair a bha \u00e0ite dealbhaidh cuingealaichte.<\/p>\n Dh\u2019 fhaodadh tu a bhith air do iongnadh cho cumhachdach \u2018s a dh\u2019 fhaodas neomagnet beag a bhith.<\/p>\n Is iad magnetan neodymium na magnetan maireannach malairteach as cumhachdaiche, le toraidhean l\u00f9th as \u00e0irde (BHmax) a\u2019 ruighinn suas gu 52 MGOe.<\/strong><\/p>\n Tha neomagnets grunn chudromach de fheartan magnetach:<\/p>\n Ann am pr\u00f2iseact cumhachd gaoithe o chionn ghoirid, thug sinn solaraichean magnetan N52 le BHmax \u00e0rd gus torque a leasachadh fhad \u2018s a bha sinn a\u2019 l\u00f9ghdachadh meud iomlan an motair. Dh\u2019fhaodadh seo caitheamh l\u00f9th a lughdachadh le 10%.<\/p>\n Tha iad l\u00e0idir\u2014ach so-le\u00f2nte. Sin as coireach gu bheil c\u00f2mhdachan riatanach.<\/p>\n Tha magnetan neodymium fo chunnart bho chreachadh agus feumaidh iad c\u00f2mhdachan d\u00econ mar Ni-Cu-Ni, epoxy, no \u00f2r.<\/strong><\/p>\n Tha stuth NdFeB a\u2019 meirg gu furasta ann an \u00e0rainneachdan taise. Sin as coireach gu bheil c\u00f2mhdachan cudromach, gu s\u00f2nraichte ann an tagraidhean meidigeach no mara.<\/p>\n C\u00f2mhdachan cumanta:<\/strong><\/p>\n Air a mholadh magnetan N42 le c\u00f2mhdach \u00f2ir airson aon neach-d\u00e8iligidh anns a' ghn\u00ecomhachas innealan-lann surgical, a' tabhann seasmhachd, co-ch\u00f2rdalachd le bodhaig, agus beatha st\u00f2raidh nas fhaide.<\/p>\n Tha cothrom ann gu bheil thu a' cleachdadh neomagnetan gach latha\u2014gun eagal a bhith agad eadhon.<\/p>\n Tha magnetan neodymium air an cleachdadh ann an electronics, c\u00e0r dealain, turban-adhair, agus innealan meidigeach air sg\u00e0th an meud teann agus cumhachd magnetach l\u00e0idir.<\/strong><\/p>\n Aig mo e\u00f2las, aon de na cleachdaidhean as inntinniche tha e ann an motaran gun scuab \u00e0rd-astar. Leigidh magnetan neodymium innleadairean \u00e0rdachadh toradh gun a bhith a' cur meud no cuideam ris.<\/p>\n Tha na magnetan seo l\u00e0idir\u2014ach cuideachd brisgte agus cunnartach ma th\u00e8id an l\u00e0imhseachadh gu m\u00ec-fhiosrach.<\/p>\n C\u00f9m na neomagnetan gu c\u00f9ramach gus casg a chur air gortno, milleadh, no eadar-obrachadh le electronics.<\/strong><\/p>\n Bha aon neach-d\u00e8iligidh air grunn mhagnataichean briste r\u00e8 c\u00f2mhdhail. \u00c0s d\u00e8idh dhaibh atharrachadh gu pacaid vacuum-sealed le sp\u00e0inean foam, thuirt iad gun robh gun bhriseadh ann am sia m\u00ecosan.<\/p>\n Tha togail thalmhainn neo-eisimeileach a\u2019 togail draghan\u2014ach tha riaghailtean a\u2019 teannachadh.<\/p>\n Feumaidh maganataichean neodimium coinneachadh ri inbhean \u00e0rainneachd mar ROHS agus REACH, agus tha st\u00f2ras gu tric ag iarraidh aithisgean mu mh\u00e8innean conaltraidh.<\/strong><\/p>\n Faodaidh togail thalmhainn neo-eisimeileach mar neodimium cron a dh\u00e8anamh air coilleagan. Sin as coireach gu bheil m\u00f2ran luchd-d\u00e8anamh, a\u2019 gabhail a-steach sinn, a\u2019 co-obrachadh le solaraichean a tha a\u2019 leantainn:<\/p>\n Bha againn o chionn ghoirid feum air cuideachadh le neach-d\u00e8iligidh E\u00f2rpach a\u2019 cruinneachadh sgr\u00ecobhainnean REACH airson loidhne toraidh NdFeB. Thug sinn seachad sgaoileadh iomlan air ais chun mh\u00e8innean, a\u2019 d\u00e8anamh cinnteach gun do shleamhnaich an cead importadh gun d\u00e0il.<\/p>\n Maganataichean neodimium\u2014no neo-maganataichean\u2014\u2019s e cn\u00e0mhan-t\u00ecre an magnetachd \u00f9r-nodha. Tha an neart, meud, agus s\u00f9bailteachd aca gan d\u00e8anamh freagarrach airson fuasglaidhean teicne\u00f2lais is l\u00f9th. Ach feumaidh iad a bhith air an l\u00e0imhseachadh agus air an st\u00f2radh gu cunntachail.<\/p>\n D\u00e8 th\u2019 ann am neo-maganat? An robh thu a\u2019 smaoineachadh a-riamh d\u00e8 a tha a\u2019 toirt cumhachd do ch\u00e0r-ama dealain no do fh\u00f2n agad? Is d\u00f2cha gur e maganata neodimium a th\u2019 ann. Tha maganataichean neodimium\u2014ris an canar cuideachd neo-maganataichean\u2014an se\u00f2rsa as l\u00e0idire de maganataichean seasmhach a chaidh a dh\u00e8anamh bho neodimium, iarann, agus boron (NdFeB).
