Nga Huringa NdFeB kua hara



Whakaahuatanga

Ko nga tohu taapiri NdFeB hara kua tino kaha ki nga miihini tuturu tino kaha e waatea ana i tenei ra, me te hua pūngao tino nui mai i te 26 MGOe ki te 52 MGOe. Ko te Nd-Fe-B te toru o nga whakatipuranga o te aukume pumau i hangaia i te tau 1980. He huihuinga nui rawa atu me te aukati, me te maha o nga reanga, te rahi me nga ahua. Na ona ahuatanga pai o te miihini, te nui o nga rauemi mata me te iti o te utu, ka taea e Nd-Fe-B te maamaatanga ki te hoahoa hou, ki te whakakapi ranei i nga taonga orite penei i te whakaari, Alnico me te Sm-Co kia tutuki ai te kaha o te mahi, te utu iti me te maha atu pepapātū raka.


Painga o te Maketini kua hara
* Whakanoho kaha i te Takiwa o Br.
* Kairangi ātete demagnetization pai.
* He Pai Momo e pa ana ki ana taonga whakarewa.
