Neodymium magineti ndiwo akanakisa asingadzoreki magineti anotengeswa, chero kupi zvako pasirese. kuramba kune demagnetization kana ichienzaniswa neferrite, alnico uye kunyange samarium-cobalt magineti.
✧ Neodymium magineti VS akajairwa ferrite magineti
Ferrite magineti asiri-metallic material magineti anobva pa triiron tetroxide (fixed mass ratio ye iron oxide kune ferrous oxide). Chinonyanya kukanganisa magineti aya ndechekuti haagone kugadzirwa pamadiro.
Neodymium magineti haangove neakanakisa simba remagineti chete, asi zvakare ane yakanaka michina zvimiro nekuda kwekusanganiswa kwesimbi, uye anogona kugadziriswa nyore kuita akasiyana maumbirwo kuti aenderane nezvakawanda zvinodikanwa. Izvo zvisingabatsiri ndezvokuti simbi monomers mu neodymium magineti zviri nyore kuita ngura uye kushata, saka nzvimbo yacho inowanzoputirwa nickel, chromium, zinc, tin, nezvimwewo kudzivirira ngura.
✧ Kuumbwa kwe neodymium magineti
Neodymium magineti akagadzirwa neodymium, iron uye boron zvakabatanidzwa pamwechete, kazhinji kunyorwa seNd2Fe14B. Nekuda kweiyo yakagadziriswa kuumbwa uye kugona kuumba tetragonal makristasi, neodymium magineti anogona kutariswa chete kubva kune kemikari maonero. 1982, Makoto Sagawa weSumitomo Special Metals akagadzira neodymium magineti kekutanga. Kubva ipapo, magineti eNd-Fe-B akabviswa zvishoma nezvishoma kubva kumagineti eferrite.
✧ Ko neodymium magineti anogadzirwa sei?
STEP 1- Chekutanga pane zvese, zvinhu zvese zvekugadzira iyo yakasarudzwa mhando yemagineti inoiswa muvacuum cleaner induction vira, inopisa pamwe nekunyungudutswa kugadzira iyo alloy chigadzirwa. Musanganiswa uyu unozotonhodzwa pasi kuti ugadzire ingots isati yakuyiwa kuita tsanga diki muchigayo chejeti.
STEP 2- Iyo yepamusoro-yakanaka poda inozotsikirirwa muforoma uye panguva imwecheteyo simba remagineti rinoiswa kune mold. Magnetism inobva mukoiri yetambo inoita semagineti kana magetsi achipfuura nepairi. Kana iyo particle framework yemagineti ichienderana nemirairo yemagnetism, iyi inonzi anisotropic magineti.
STEP 3- Uku hakusi kupera kwemaitiro, panzvimbo ino, panguva ino iyo magnetised material yakabviswa magineti uye ichave ine magineti gare gare uchiita kudaro. Danho rinotevera nderekuti zvinhu zvipiswe, kusvika pakunyungudika nenzira inodaidzwa kuti Chiito chinotevera ndechekuti chigadzirwa chipiswe, kuda kusvika pakunyungudika nenzira inodaidzwa kunzi sintering inoita kuti magineti ehupfu abatane. Iyi nzira inoitika munzvimbo isina oxygen, inert setting.
STEP 4- Kunenge ikoko, zvinhu zvinopisa zvinokurumidza kutonhodzwa pasi uchishandisa nzira inozivikanwa sekudzima. Iyi inokurumidza kutonhora maitiro inoderedza nzvimbo dzeakaipa magnetism uye zvakare inowedzera kuita.
STEP 5-Nekuda kwekuti neodymium magineti akaomarara, achivaita kuti vatadze kukuvadza uye kukuvadza, anofanirwa kuvezwa, kucheneswa, kuomeswa, uye kuputirwa. Kune akawanda akasiyana marudzi ekupedzisa ayo anoshandiswa neneodymium magineti, imwe yeanonyanyo zivikanwa kuva nickel-copper-nickel musanganiswa asi anogona kunamwa mune dzimwe simbi uyewo rabha kana PTFE.
STEP6- Pakangoputirwa, chigadzirwa chakapedzwa chinodzoserwa magineti nekuchiisa mukati mecoil, iyo, kana magetsi ekufambisa achifambiswa mukati mayo anoburitsa magineti ane simba rakapetwa katatu pane inodiwa kuoma kwemagineti. Iyi inzira inoshanda zvekuti kana magineti ikasachengetwa munzvimbo inogona kukandwa kubva pacoil-sebara.
AH MAGNET iIATF16949, ISO9001, ISO14001 uye ISO45001 yakatenderwa kugadzira marudzi ese emhando yepamusoro neodymium magineti uye magineti magineti ane anopfuura makore makumi matatu echiitiko mumunda. Kana iwe uchifarira neodymium magineti, ndapota inzwa wakasununguka kutibata nesu!
