Seýrek ýer magnitleriniň görnüşleri

Samarium KobaltMagnetGysgaça syn we aýratynlyklar:

Samarium Kobalt (SmCo) magnitine seýrek toprak Kobalt magnit hem diýilýär. Onuň demagnetizasiýa garşy ýokary garşylygy we ajaýyp temperatura durnuklylygy SmCo-ny ýokary temperatura magnitini ýa-da Sm2Co17 magnitini 350 ° C-den ýokary temperaturada durnukly işlemäge mejbur edýär. Adatça örtük gerek däl. Şonuň üçin SmCo magnit, aerokosmos, awtoulag sporty we awtoulag senagaty ýaly köp öndürijilikli programmalar üçin magnit materialynyň iň ýokary seçimidir.

Magnit howpsuzlygy:

Seýrek ýer magnitleri ýa-da magnit ulgamlary gaty güýçli, şonuň üçin şahsy şikeslerden ýa-da magnitlere zeper ýetmezligi üçin aşakdaky howpsuzlyk çäreleri olary ulanyp, dolandyryp ýa-da gaýtadan işleýän ähli işgärleriň dykgatyna ýetirilmelidir.

Magnitleşdirilen seýrek ýer magnitleriniň biri-biri ýa-da ferromagnit materiallar bilen gatnaşyga girenlerinde gözegçilikde saklanýandygyna göz ýetiriň. Uly magnitler ulanylanda howpsuzlyk äýnegi we beýleki degişli gorag enjamlary geýmek möhümdir. Eliňizi goramak üçin ellik geýmek hem maslahat berilýär.

Ferromagnit metallary iş meýdanyndan uzakda saklaň. Magnitler bilen işleýän wagtyňyz ünsli boluň. Alkogolyň, neşe serişdeleriniň ýa-da gözegçilik edilýän maddalaryň täsiri astynda magnitli magnitler bilen işlemäň.

Duýgur elektron gurallary we enjamlary kalibrlemäni üýtgedip biler ýa-da güýçli magnit meýdany zaýalanmagy mümkin. Magnitleşdirilen magnitleri elmydama duýgur elektron gurallaryndan uzak aralykda saklaň. Elektrokardiostimulýator geýýän bolsa, aýratyn seresap bolmaly, sebäbi güýçli magnit meýdanlary elektrokardiostimulýatorlaryň içindäki elektronikany zaýalap biler.

Hiç haçan magnitleri ýuwutmaň ýa-da magnitleri çagalaryň ýa-da akyl taýdan kemçilikli ulularyň elinde goýmaň. Magnitler ýuwudylsa, derrew lukmana ýüz tutuň we / ýa-da derrew lukmançylyk kömegini alyň.

Seýrek ýer magnitleri, esasanam bilelikde täsir etmäge rugsat berilende, aragatnaşykda uçgun döredip biler. Hiç haçan partlaýjy atmosferada seýrek ýer magnitlerini ulanmaň, sebäbi uçgun bu atmosferany ýakyp biler.

Seýrek toprak tozy ýanýar; Poroşok gury bolanda öz-özünden ýanmak bolup biler. Öwürýän bolsa, üweýji swarfyň öz-özünden ýanmazlygy üçin elmydama çygly üwüriji magnitler. Hiç haçan üwürmäň. Magnitleri üwende, ýeterlik howa çalşygynyň bardygyna göz ýetiriň. Adaty gurallary ulanyp, magnitleri işlemäge synanyşmaň, sebäbi bu çişirip we döwüp biler. Elmydama howpsuzlyk äýnegi geýiň.

Öz-özünden ýanmagynyň öňüni almak üçin elmydama seýrek toprak tozy ýa-da üweýji suwy doldurylan gaplarda ýa-da germetiki möhürlenen inert atmosferalarynda saklaň.

Elmydama seýrek toprak tozanyny seresaplyk bilen taşlaň. Esangyn howpuna duçar bolmaň. Magnitleşdirilen magnitleri taşlamak, işlenende şikes ýetmeginiň öňüni almak üçin edilmelidir.
