Samarium CobaltMagnetTrosolwg a Manylebau:
Gelwir magnet Samarium Cobalt (SmCo) hefyd yn fagnet Cobalt daear prin. Mae ei wrthwynebiad uchel i ddadmagneteiddio a sefydlogrwydd tymheredd rhagorol yn golygu bod magnet tymheredd uchel SmCo neu fagnet Sm2Co17 yn gweithio'n sefydlog o dan dymheredd uchel i 350 ° C. Fel arfer nid oes angen cotio. Felly mae magnet SmCo yn ddewis premiwm o ddeunydd magnet ar gyfer llawer o gymwysiadau perfformiad uchel fel diwydiannau awyrofod, chwaraeon moduro a modurol.

Diogelwch Magnet:
Mae magnetau daear prin neu systemau magnetig yn hynod o gryf, felly rhaid dwyn y rhagofalon diogelwch isod i sylw'r holl bersonél a all eu defnyddio, eu trin neu eu prosesu er mwyn osgoi anaf personol neu ddifrod i fagnetau.
Sicrhewch fod magnetau daear prin magnetedig dan reolaeth pan fyddant yn dod i gysylltiad â'i gilydd neu ddeunyddiau ferromagnetig. Mae'n bwysig gwisgo sbectol diogelwch a gêr amddiffynnol priodol eraill wrth drin magnetau mawr. Argymhellir gwisgo menig i amddiffyn eich dwylo hefyd.
Cadwch fetelau ferromagnetig i ffwrdd o'r ardal waith. Byddwch yn sylwgar wrth weithio gyda magnetau. Peidiwch â gweithio gyda magnetau magnetedig os ydych chi dan ddylanwad alcohol, cyffuriau neu sylweddau rheoledig.
Gall offerynnau a dyfeisiau electronig sensitif newid graddnodi neu gael eu difrodi gan faes magnetig pwerus. Cadwch magnetau magnetedig bob amser bellter diogel i ffwrdd o offerynnau electronig sensitif. Dylid bod yn arbennig o ofalus os yw un yn gwisgo rheolydd calon, oherwydd gall meysydd magnetig cryf niweidio'r electroneg y tu mewn i'r rheolyddion calon.
Peidiwch byth â llyncu magnetau na gosod magnetau o fewn cyrraedd plant neu oedolion â nam meddyliol. Os caiff magnetau eu llyncu, ymgynghorwch â meddyg ar unwaith a / neu ceisiwch sylw meddygol ar unwaith.
Gall magnetau pridd prin greu gwreichion trwy gyswllt wrth drin, yn enwedig pan ganiateir iddynt daro gyda'i gilydd. Peidiwch byth â thrin magnetau daear prin mewn atmosfferau ffrwydrol oherwydd gall gwreichionen danio'r atmosffer hwnnw.
Mae powdr daear prin yn hylosg; gall hylosgiad digymell ddigwydd pan fydd y powdr yn sych. Os yw'n malu, mae magnetau malu gwlyb bob amser er mwyn osgoi hylosgiad digymell y swarf malu. Peidiwch byth â malu sych. Sicrhewch fod gennych awyru digonol wrth falu magnetau. Peidiwch â cheisio peiriannu magnetau gan ddefnyddio offer confensiynol, oherwydd gall hyn achosi naddu a chwalu. Gwisgwch sbectol diogelwch bob amser.
Storio powdr pridd prin neu swarf malu bob amser mewn cynwysyddion llawn dŵr neu atmosfferau anadweithiol wedi'u selio'n hermetig i atal hylosgiad digymell.
Gwaredwch bowdr pridd prin yn ofalus bob amser. Peidiwch â pheryglu tanau. Rhaid gwaredu magnetau magnetedig er mwyn atal anaf wrth drin.
