He aha nā magnet Neodymium a me Samarium Cobalt?

Nā Mākēneki Neodymium i ka Pōkole

ʻOiai ʻo ia ka magnet honua laha loa ma ka mākeke kalepa, kaena ʻo NdFeB i ka ikehu magnetic kiʻekiʻe loa a me ka ikaika huki ikaika.

Nā Mākēneki Samarium Cobalt i ka pōkole

ʻO nā magnet Samarium Cobalt (SmCo) he mau mea magnetic honua laha ʻole i haku ʻia me nā mea samarium a me cobalt. ʻAʻole e like me nā magnet NdFeB, ʻoi aku ka maikaʻi o nā huahana SmCo i ke kūpaʻa ʻana i ke kaiapuni koʻikoʻi, e hōʻike ana i ke ahonui wela kiʻekiʻe loa, ka hiki ke pale aku i ka demagnetization, a me ke kūpaʻa kūlohelohe i ka corrosion me ka ʻole o ka mālama ʻana i ka uhi ʻili paʻakikī.

He haʻahaʻa iki ka helu ikehu magnetic o nā magnet samarium cobalt i hoʻohālikelike ʻia me nā huahana neodymium premium. Eia nō naʻe, kūpaʻa mau kā lākou hana magnetic ma o ka wela nui, nā loli o ka mahana a me ka hoʻopili kemika. ʻOi aku ke kumukūʻai o ka hana ʻana, akā naʻe, ʻo kā lākou hana hilinaʻi e hoʻolilo iā lākou i mea hiki ʻole ke hoʻololi ʻia no nā papahana ʻoihana kiʻekiʻe.

I ka manawa hea e koho ai i nā magnet NdFeB

ʻO nā magnet Neodymium ke koho kūpono loa no ka hapa nui o nā hiʻohiʻona ʻoihana a me nā kalepa maʻamau. Inā kū kāu wahi hana i nā kūlana aʻe, e hāʻawi ʻo NdFeB i ke kaulike maikaʻi loa o ka hana a me ke kumukūʻai:

- Ka mahana hana paʻa ma lalo o 150°C me ka ʻole o nā piʻi wela koʻikoʻi

- Ua kaupalena ʻia nā kālā papahana, e koi ana i nā hoʻonā hana nui kūpono

Ka Manaʻo Hana Hana mai Fullzen Technology

I ko mākou mau makahiki o ka hana ʻana a me ka lawelawe papahana ma Fullzen Technology, ua hālāwai mākou me kahi kuhi hewa ʻenekinia maʻamau: ʻo ka hapa nui o nā mea kūʻai aku e nīnau mua i ka magnet nona ka magnetism ikaika, ʻoiai ʻo ka nīnau nui e pono ai ʻo ia ka mea e mālama i ka hana paʻa i ko lākou mahana kikoʻī a me nā kūlana kaiapuni. ʻAʻohe manaʻo o ka ikaika magnetic inā hāʻule mua ka magnet i ka hana maoli.

Hana mākou i nā magnet NdFeB a me SmCo i loko o ka hale. Ma mua o ka nānā wale ʻana i nā helu hana pākahi, hana mākou i nā mea i hana kūikawā ʻianā hoʻonā makeneka honua laha maʻamaua puni kāu mau kūlana hana maoli.

Pehea e hana ai i ke koho kūpono

Inā ʻo ke kumukūʻai ka mea nui loa

Ke kaohi ʻia ka waihona kālā o ka papahana ka pahuhopu nui a ʻo nā kūlana hana he mau wahi maloʻo maʻamau i loko me nā mahana ma lalo o 150°C, ʻo nā magnet neodymium ka hopena kūpono loa. Me nā ʻano like ʻole, nā kaʻina hana hana nui, a me nā uhi pale koho, hoʻokō piha lākou i nā pono o nā mea uila mea kūʻai aku, nā lako hana automation maʻamau, a me nā papahana hōʻuluʻulu nui.

Inā ʻo ke kūpaʻa wela ka mea nui loa

No nā lako e hana ana ma luna o 150°C a i ʻole e hoʻomau nei i ka hoʻopōʻaiapuni wela pinepine, ʻaʻole hiki ke kūkākūkā ʻia nā magnet samarium cobalt. ʻO ko lākou kūpaʻa wela kiʻekiʻe maikaʻi loa a me ka hana anti-demagnetization e pale aku i ka attenuation magnetic a me ka hāʻule ʻana o nā lako i hoʻokumu ʻia e ka wela, e hōʻoiaʻiʻo ana i ka hana paʻa lōʻihi o nā lako ʻoihana wela kiʻekiʻe.

Inā ʻo ke kūpaʻa i ka pala ka mea nui loa

I nā wahi haumī, kai, saline, a i ʻole nā ​​​​​​wahi ʻino kemika, hōʻike nā magnet SmCo i nā pono kūlohelohe. ʻAʻole e like me nā magnet NdFeB e hilinaʻi nei i ka uhi epoxy a i ʻole nickel no ka pale ʻana, ʻo nā mea SmCo ponoʻī he kūpaʻa i ka pala, e pale ana i ka ʻili ʻana o ka uhi, ka oxidation substrate, a me ka hōʻino ʻana o ka hana i hoʻokumu ʻia e ka ʻino o ke kaiapuni.
