Magineti eNeodymium ndiwo magineti akanakisa asingadzoreki anotengeswa, chero kupi zvako pasi rose. Kudzivirira demagnetisation kana tichienzanisa nemagineti eferrite, alnico uye kunyange samarium-cobalt.
✧ Magineti eNeodymium VS magineti eferrite akajairwa
Magineti eFerrite magineti asiri esimbi anobva patriiron tetroxide (chiyero chakagadzika chesimbi oxide kune ferrous oxide). Dambudziko guru remagineti aya nderekuti haagone kugadzirwa chero nguva.
Magineti eNeodymium haana simba remagineti chete, asiwo ane hunhu hwakanaka hwemakanika nekuda kwekusanganiswa kwesimbi, uye anogona kugadziriswa zviri nyore kuita maumbirwo akasiyana-siyana kuti akwane zvinodiwa zvakasiyana-siyana. Dambudziko nderekuti mamonomer esimbi ari mumagineti eNeodymium ari nyore kuita ngura uye kuora, saka pamusoro pawo panowanzo putirwa nickel, chromium, zinc, tin, nezvimwewo kudzivirira ngura.
✧ Kuumbwa kwemagineti e neodymium
Magineti eNeodymium anogadzirwa ne neodymium, iron ne boron zvakabatana, zvinowanzo nyorwa seNd2Fe14B. Nekuda kwechimiro chakasimba uye kugona kugadzira makristaro e tetragonal, magineti eNeodymium anogona kutariswa chete kubva pamaonero emakemikari. 1982, Makoto Sagawa weSumitomo Special Metals akagadzira magineti eNeodymium kekutanga. Kubva ipapo, magineti eNd-Fe-B akabviswa zvishoma nezvishoma kubva kumagineti eFerite.
✧ Magineti eNeodymium anogadzirwa sei?
Danho 1- Chekutanga, zvinhu zvese zvinogadzira mhando yemagnet zvinoiswa muchoto chevacuum cleaner, zvinodziiswa pamwe nekunyungudutswa kuti pave nechigadzirwa chealloy. Musanganiswa uyu unotonhodzwa kuti ugadzire ma ingots usati wakuyiwa kuita zvidimbu zvidiki mujet mill.
Danho rechipiri- Hupfu hwakatsetseka kwazvo hunozodzvanywa muchimiro uye panguva imwe chete simba remagineti rinoiswa pachimiro. Magnetism inobva patambo inoshanda semagineti kana magetsi emagetsi achipfuura nepakati payo. Kana chigadziko chemagineti chikaenderana nemirairo yemagnetism, ichi chinonzi magineti anisotropic.
NHANHO YECHITATU- Uku hakusi kuguma kwemaitiro, asi, panguva ino zvinhu zvine magineti zvinenge zvabviswa magineti uye zvichazopedzisira zvaiswa magineti gare gare panguva iyoyo. Danho rinotevera nderekuti zvinhu zvipiswe, kusvika pakunyunguduka mumaitiro anonzi Chiito chinotevera ndechekuti chigadzirwa chipiswe, kusvika pakunyunguduka mumaitiro anonzi sintering anoita kuti magineti epoda asanganiswe pamwe chete. Maitiro aya anoitika munzvimbo isina oxygen, isina simba.
NHANHO YECHINA- Zviripo ipapo, chinhu chinodziya chinotonhodzwa nekukurumidza uchishandisa nzira inozivikanwa sekudzima. Maitiro ekutonhodza nekukurumidza aya anoderedza nzvimbo dzine magineti akaipa uye anowedzerawo mashandiro.
NHANHO 5- Nekuda kwekuti magineti e neodymium akaomarara, zvichiita kuti akuvadzwe nekukuvadzwa, anofanira kuputirwa, kucheneswa, kuomeswa, uye kuputirwa. Kune mhando dzakasiyana-siyana dzekupedzisa dzinoshandiswa nemagineti e neodymium, imwe yeanonyanya kushandiswa iri musanganiswa we nickel-copper-nickel asi inogona kuputirwa nedzimwe simbi pamwe nerabha kana PTFE.
NHANHO 6- Kana yangoiswa simbi, chigadzirwa chapera chinodzokororwazve nekuchiisa mukati me coil, iyo, kana magetsi emagetsi achifamba nepakati payo anogadzira simba remagineti rakapetwa katatu kupfuura kusimba kwakakodzera kwegineti. Iyi inzira inoshanda zvekuti kana magineti ikasachengetwa panzvimbo yacho inogona kukandirwa kubva mu coil sebara.
AH MAGNET inyanzvi yekugadzira magineti emhando dzakasiyana-siyana dzemagineti emhando yepamusoro ane magineti ane ruzivo rwemakore anopfuura makumi matatu mubasa iri. Kana uchida magineti emhando yepamusoro, ndapota taura nesu!
