Samarium CobaltMàidseantSealladh farsaing agus sònrachaidhean:
Canar magnet Cobalt talmhainn tearc ri magnet Samarium Cobalt (SmCo). Tha an aghaidh àrd aige an aghaidh demagnetization agus seasmhachd teothachd sàr-mhath a’ toirt air magnet teòthachd àrd SmCo no magnet Sm2Co17 obrachadh seasmhach fo theodhachd àrd gu 350 ° C. Mar as trice chan eil feum air còmhdach. Mar sin tha SmCo magnet na phrìomh roghainn de stuth magnet airson mòran thagraidhean àrd-choileanaidh leithid gnìomhachasan aerospace, spòrs motair agus càraichean.

Neodymium MàidseantSealladh farsaing agus sònrachaidhean:
Tha grunn thagraidhean aig magnet Neodymium (NdFeB), Neo, no Neodymium Iron Boron mar motaran DC gun bhruis, mothachairean agus glaodhairean, mar thoradh air na feartan sònraichte aige leithid feartan magnetach nas àirde (a ’toirt a-steach inntrigeadh fuigheall, feachd co-èigneachail, agus an toradh lùth as àirde), barrachd roghainnean de ìrean magnetach agus teòthachd obrachaidh, nas fhasa ann an innealachadh gus mòran chumaidhean is mheudan a thoirt seachad, msaa.

Sàbhailteachd Magnet:
Tha magnets tearc talmhainn no siostaman magnetach air leth làidir, agus mar sin feumar na ceumannan sàbhailteachd gu h-ìosal a thoirt gu aire gach neach-obrach a dh’ fhaodadh an cleachdadh, an làimhseachadh no an giullachd gus dochann pearsanta no milleadh air magnets a sheachnadh.
Dèan cinnteach gu bheil magnets talmhainn tearc magnetach fo smachd nuair a thig iad an conaltradh ri chèile no stuthan ferromagnetic. Tha e cudromach glainneachan sàbhailteachd agus gèar dìon iomchaidh eile a chaitheamh nuair a bhios tu a’ làimhseachadh magnets mòra. Thathas cuideachd a’ moladh miotagan a chaitheamh gus do làmhan a dhìon.
Cùm meatailtean ferromagnetic air falbh bhon raon obrach. Bi faiceallach nuair a bhios tu ag obair le magnets. Na bi ag obair le magnets magnetach ma tha thu fo bhuaidh deoch làidir, drogaichean no stuthan fo smachd.
Faodaidh ionnstramaidean agus innealan dealanach mothachail calibration atharrachadh no a bhith air am milleadh le raon magnetach cumhachdach. Cùm magnets magnetach an-còmhnaidh astar sàbhailte air falbh bho ionnstramaidean dealanach mothachail. Bu chòir a bhith faiceallach ma tha inneal-pacaidh air aon neach, oir faodaidh raointean magnetach làidir cron a dhèanamh air an electronics taobh a-staigh luchd-pacaidh.
Na sluig a-riamh magnets no cuir magnets taobh a-staigh ruigsinneachd chloinne no inbhich le duilgheadasan inntinn. Ma thèid magnets a shlugadh, bruidhinn ri dotair sa bhad agus / no faigh aire mheidigeach sa bhad.
Faodaidh magnets tearc talmhainn sradagan a chruthachadh tro cheangal ann an làimhseachadh, gu sònraichte nuair a gheibh iad cead buaidh còmhla. Na bi a-riamh a’ làimhseachadh magnets talmhainn tearc ann an àileachdan spreadhaidh oir faodaidh sradag an àile sin a lasadh.
Tha pùdar talmhainn tearc a ghabhas losgadh; faodaidh losgadh gun spionnadh tachairt nuair a tha am pùdar tioram. Ma bhios tu a’ bleith, an-còmhnaidh fliuch magnaitean bleith gus nach bi an sgaoth bleith a’ losgadh gun spionnadh. Na bi a 'bleith a' tiormachadh a-riamh. Dèan cinnteach gu bheil fionnarachadh iomchaidh agad nuair a bhios tu a’ bleith magnets. Na feuch ri innealachadh magnets le bhith a’ cleachdadh innealan àbhaisteach, oir faodaidh seo sgoltadh agus briseadh a thoirt gu buil. Cleachd glainneachan sàbhailteachd an-còmhnaidh.
Stèidhich an-còmhnaidh pùdar talmhainn tearc no swarf bleith ann an soithichean làn uisge no ann an àileachdan inert seulaichte gus casg a chuir air losgadh gun spionnadh.
Thoir air falbh pùdar talmhainn tearc an-còmhnaidh le cùram. Na cuir an cunnart teine. Feumar faighinn cuidhteas magnets magnetach gus casg a chuir air dochann nuair a thathar ga làimhseachadh.
