Isi ihe na-emetụta demagnetization nke NdFeB magnetik

Okpomọkụ bụ otu n'ime isi ihe nwere ike ibute demagnetization na ndọta NdFeB. Ihe ndọta ndị a nwere aokpomọkụ kacha arụ ọrụ, karịa nke ha na-amalite ịla n'iyi magnetik ha. Okpomọkụ Curie bụ ebe ihe ndọta na-eme mgbanwe nke oge, na-eduga n'ọdịda dị ịrịba ama na magnetization ya. Maka ndọta NdFeB, okpomọkụ Curie dị gburugburu 310 degrees Celsius. Yabụ, ịrụ ọrụ ndọta na okpomọkụ dị nso ma ọ bụ karịa oke a nwere ike ibute demagnetization.

Ihe ọzọ dị mkpa na-emetụta demagnetization nke NdFeB ndọta bụ oghere ndọta. Ikpughe ndọta n'ebe ndọta siri ike na-emegide ya nwere ike ime ka ndọta ya kwụsị. A maara ihe a dị ka demagnetizing. Ike na ogologo oge nke ogige dị n'èzí na-arụ ọrụ dị mkpa na usoro demagnetization. Ya mere, ọ dị mkpa iji nlezianya jikwaa ndọta NdFeB ma zere ikpughe ha na oghere magnetik siri ike nke nwere ike imebi ihe ndọta ha.

Corrosion bụkwa ihe dị mkpa nke nwere ike iduga demagnetization nke ndọta NdFeB. A na-eji ọla ọla mee ihe ndọta ndị a, ma ọ bụrụ na a kpughee ha na mmiri ma ọ bụ kemịkal ụfọdụ, ha nwere ike imebi. Corrosion na-ebelata iguzosi ike n'ezi ihe nke ndọta ma nwee ike ime ka ike ndọta ya kwụsị. Iji gbochie nke a, a na-etinyekarị ihe mkpuchi dị ka nickel, zinc, ma ọ bụ epoxy iji chebe ihe ndọta site na mmiri na ihe ndị na-emebi emebi.

Nchegbu n'ọrụ bụ ihe ọzọ nwere ike ịkpata demagnetization na ndọta NdFeB. Nnukwu nrụgide ma ọ bụ mmetụta nwere ike imebi nhazi nke ngalaba magnetik n'ime magnet, na-ebute mbelata ike magnetik ya. Ya mere, ọ dị mkpa iji nlezianya jikwaa ndọta NdFeB ka ịzenarị itinye ike gabigara ókè ma ọ bụ tinye ha na mmetụta mberede.

N'ikpeazụ, oge n'onwe ya nwekwara ike jiri nwayọọ nwayọọ mee ka demagnetization na NdFeB magnetik. A maara nke a dị ka ịka nká. N'ime ogologo oge, ihe ndọta magnetik nwere ike ịla n'iyi n'ihi ihe dị iche iche dị ka mgbanwe okpomọkụ, ikpughe na oghere magnetik dị n'èzí, na nrụgide ọrụ. Iji belata mmetụta nke ịka nká, a na-atụ aro ịnwale na nleba anya nke ihe ndọta magnetik.

Na mmechi, ọtụtụ ihe nwere ike imetụta demagnetization nke NdFeB magnetik, gụnyere okpomọkụ, mpụga magnetik, corrosion, n'ibu nrụgide, na ịka nká. Site n'ịghọta na ijikwa ihe ndị a nke ọma, ọ ga-ekwe omume ichekwa ihe ndọta siri ike nke ndọta NdFeB ma gbatịa ndụ ha. Ijikwa nke ọma, njikwa okpomọkụ, na nchebe megide gburugburu ebe ndị na-emebi emebi bụ isi ihe dị mkpa n'ịkwado ọrụ ndọta.
