ʻO Samarium Cobalt Mʻumeʻume Overview a me nā lula.
ʻO Samarium Cobalt (SmCo) magnet ka mea i kapa ʻia ka magnet magnet Cobalt honua. ʻO kona kūpaʻa kiʻekiʻe i ka demagnetization a me ke kūpaʻa o ke ana wela maikaʻi e hana SmCo magnet wela kiʻekiʻe a i ʻole Sm2Co17 magnet e hana paʻa ma lalo o ke ana wela i 350 ° C. ʻO ka maʻamau ʻaʻole pono ka uhi ʻana. No laila SmCo Mākēneki mea he uku nui koho o ka Mākēneki mea no na mea he nui kiʻekiʻe hana noi e like me aerospace, motorsports a me kaʻa hana.

Mākēneki palekana:
Nui ka ikaika o nā mākēneki lā a me nā ʻōnaehana magnet, no laila pono e mālama ʻia ka mālama pono ʻana i lalo i ka maka o nā limahana āpau e hoʻohana, lawelawe, a i ʻole hana iā lākou i mea e hōʻeha ai i nā ʻeha pilikino a i ʻole nā pōʻino i nā mākēneki.
E nānā pono ka mālama ʻia ʻana o nā mākēneki laha honua ākea ka wā e pili ai kekahi me kekahi a i ʻole nā mea ferromagnetic. He mea nui e komo i nā aniani palekana a me nā mea pale e pono ai ke lawelawe ʻana i nā mākēneki nui. Paipai ʻia nā kāʻei lima e pale ai i nā lima.
E mālama i nā metala ferromagnetic mai kahi hana. E akahele i ka hana ʻana me nā mākēneki. Mai hana pū me nā mākēneki magnetized inā ʻoe ma lalo o ka mana o ka ʻalekohola, nā lāʻau, a i ʻole nā lāʻau hoʻomalu.
Hoʻololi paha nā mea uila uila a me nā hāmeʻa i ka hoʻoponopono ʻana a i ʻole hōʻino ʻia e kahi māpuna ikaika. E mālama mau i nā mākēneki magnetized i kahi mamao mamao aku mai nā mea uila uila. Pono e mālama ʻia ke akahele kūikawā inā e kau ana kekahi i ka mea hoʻāʻau pacemaker, no ka mea hiki i nā māpuna ikaika ikaika ke hoʻopōʻino i nā uila uila i loko o nā mea hoʻāla.
Mai ale wale i nā mākēneki a i ʻole hoʻokau i nā mākēneki i loko o ka hiki ʻana o nā keiki a me nā mākua kīnā ʻole noʻonoʻo. Inā e ale ʻia nā mākēneki, e nīnau koke i ke kauka a / a i ʻole e ʻimi koke i ka lāʻau.
Hiki i nā mākēneki ka honua ke hana i nā huna ahi ma o ka hoʻopili ʻana i ka lawelawe ʻana, keu hoʻi ke ʻae pū ʻia. Mai lawelawe i nā mākēneka honua laha ʻole i nā lewa pā pōhaku no ka mea e ʻā ana ka uila i kēlā lewa.
Hiki ke wela i ka lepo pauka; Hiki ke puhi kūlohelohe ke maloʻo ka pauka. Inā wili, hoʻomaʻū mau i nā mākēneki mākū e hōʻalo i ka puhi wale ʻana o ka pua wili. Mai hoʻomaloʻo maloʻo. E hōʻoia i ka loaʻa ʻana o ka ea kūpono i ka wili ʻana i nā mākēneki. Mai hoʻāʻo e mīkini i nā mākēneki me ka hoʻohana ʻana i nā pono hana maʻamau, no ka mea hiki i kēia ke hana i ka chipping a me ka wāwahi ʻana. E komo mau i nā aniani palekana
E mālama mau i ka lepo kaola a i ʻole ka wili palaoa i loko o nā ipu piha piha i ka wai a i ʻole hermetically i hoʻopaʻa ʻia i nā lewa kūpale e pale ai i ka puhi koke ʻana.
E hoʻolei mau i ka pauka lepo laha ʻole me ka mālama. Mai makaʻu i nā ahi. Pono e hana i nā mākēneki magnetized e pale ai i ka ʻeha ke lawelawe.
