Cobalt Samarium Magnet Sealladh farsaing agus specs:
Canar magnet Samarium Cobalt (SmCo) cuideachd ri magnet Cobalt talmhainn ainneamh. Tha an neart àrd aige an aghaidh demagnetization agus seasmhachd teòthachd sàr-mhath a ’toirt air SmCo magnet teòthachd àrd no magnet Sm2Co17 a bhith ag obair seasmhach fo theodhachd àrd gu 350 ° C. Mar as trice chan eil feum air còmhdach sam bith. Mar sin tha magnet SmCo na phrìomh roghainn de stuth magnet airson mòran thagraidhean àrd-choileanadh leithid aerospace, motorsports agus gnìomhachasan fèin-ghluasadach.

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 a bhith gan cleachdadh, gan làimhseachadh no gan giullachd gus leòn pearsanta no milleadh magnets a sheachnadh.
Dèan cinnteach gu bheil magnets tearc 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 furachail nuair a bhios tu ag obair le magnets. Na bi ag obair le magnets magnetized ma tha thu fo bhuaidh deoch làidir, drogaichean, no stuthan fo smachd.
Faodaidh ionnstramaidean agus innealan dealanach cugallach atharrachadh calibration no a bhith air am milleadh le raon magnetach cumhachdach. Cùm magnets magnetized an-còmhnaidh astar sàbhailte air falbh bho ionnstramaidean dealanach mothachail. Bu chòir a bhith faiceallach ma tha fear a ’caitheamh pacemaker, oir faodaidh raointean làidir magnetach cron a dhèanamh air an electronics taobh a-staigh innealan-ceum.
Na sluig 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 chonaltradh ann an làimhseachadh, gu sònraichte nuair a gheibh iad cead buaidh a thoirt còmhla. Na bi a-riamh a ’làimhseachadh magnets tearc talmhainn ann an àile spreadhaidh oir is dòcha gu bheil sparradh a’ lasadh an àile sin.
Tha pùdar tearc talmhainn comasach a losgadh; faodaidh cìreadh gun spionnadh tachairt nuair a bhios am pùdar tioram. Ma tha thu a ’bleith, an-còmhnaidh fliuch a’ bleith magnets gus a bhith a ’seachnadh cìreadh gun spàin den swarf bleith. Na bi a ’tiormachadh a-riamh. Dèan cinnteach gum bi fionnarachadh iomchaidh ann nuair a bhios tu a ’bleith magnets. Na bi a ’feuchainn ri magnets inneal le bhith a’ cleachdadh innealan gnàthach, oir faodaidh seo sgoltadh agus crathadh a thoirt gu buil. Cuir glainneachan sàbhailteachd ort an-còmhnaidh.
Cùm pùdar talmhainn tearc no swarf bleith an-còmhnaidh ann an soithichean làn uisge no ann an àile neo-sheasmhach seulaichte gus casg a chuir air cìreadh gun spionnadh.
Faigh cuidhteas de phùdar talmhainn tearc le cùram. Na cuir cunnart air teintean. Feumar a bhith a ’faighinn cuidhteas magnets magnetized gus casg a chuir air dochann nuair a thathar a’ làimhseachadh.
