Neodymium magineti uye Hematite magineti zvinhu zviviri zvakajairika magineti, ayo anoshandiswa zvakanyanya muminda yavo. Neodymium magineti ndeyeRare-earth magineti, iyo inoumbwa neodymium, iron, boron uye zvimwe zvinhu. Iyo ine yakasimba magineti, yakakwirira Coercivity uye corrosion kuramba, uye inoshandiswa zvakanyanya mumotokari, jenareta, acoustic zvishandiso uye mamwe minda. Hematite magineti imhando yemhando yemhando yemagineti, iyo inonyanya kugadzirwa nehematite ine iron ore. Iyo ine zvine mwero magineti uye anti-corrosion zvivakwa, uye inonyanya kushandiswa mune zvechinyakare magineti zvinhu, dhata yekuchengetedza data uye mamwe minda.Muchikamu chino, maitiro uye mashandisirwo eNeodymium magineti uye Hematite magineti achakurukurwa zvakadzama, uye misiyano yavo ichaenzaniswa.

Ⅰ. Hunhu uye Kushandiswa kweNeodymium magineti:

A. Hunhu hweNeodymium magineti:

Kemikari yakagadzirwa:Neodymium magineti ine neodymium (Nd), iron (Fe) uye zvimwe zvinhu. Izvo zviri mukati neodymium zvinowanzova pakati pe24% ne34%, nepo zviri mukati mesimbi zvinoverengera vazhinji. Kuwedzera kune neodymium nesimbi, Neodymium magineti inogona zvakare kunge iine zvimwe zvinhu, senge boron (B) uye zvimwe zvisingawanzo zvinhu zvepasi, kuvandudza magineti ayo.

Magnetism:Neodymium magineti ndeimwe yeakasimba ekutengesa magineti anozivikanwa parizvino. Iyo ine yakanyanya kukwirisa magineti, iyo inogona kusvika pamwero usingagone kuwana mamwe magineti. Izvi zvinoipa yakanakisa magineti zvivakwa uye yakanyatsokodzera kune maapplication anoda yakakwira magineti.

Coercivity:Neodymium magineti ine yakakwirira Coercivity, zvinoreva kuti ine simba remagineti rekudzivirira uye shear kuramba. Mukushandisa, Neodymium magineti inogona kuchengetedza magineti ayo uye haibatike nyore nekunze remagineti.

Corrosion resistance:Kuramba kwecorrosion kweNeodymium magineti kunowanzo kuve kwakashata, saka kurapwa kwepamusoro, senge electroplating kana kupisa kupisa, kunowanzodikanwa kuvandudza kusakara kwayo. Izvi zvinogona kuve nechokwadi chekuti Neodymium magineti haiite kukora uye oxidation mukushandiswa.

B.Kushandiswa kwemagineti yeNeodymium:

Motokari uye jenareta: Neodymium magineti inoshandiswa zvakanyanya mumotokari uye jenareta nekuda kwekukwirira kwayo magineti uye Kumanikidza. Neodymium magineti inogona kupa yakasimba magineti, kuitira kuti mota nemajenareta zvive nehunyanzvi hwepamusoro uye kushanda.

Acoustic midziyo: Neodymium magineti inoshandiswawo mune acoustic midziyo, senge magudzanzwi uye mahedhifoni. Simba rayo remagineti rinokwanisa kuburitsa ruzha rwepamusoro uye zvirinani zvinonzwika zvemhando.Midziyo yekurapa: Neodymium magineti inoshandiswa zvakanyanya mumidziyo yekurapa. Semuyenzaniso, mune magineti resonance imaging (MRI) midziyo, Neodymium magineti anogona kuburitsa yakagadzikana magineti uye kupa mifananidzo yepamusoro.

Aerospace industry: Muindasitiri yemuchadenga, Neodymium magineti inoshandiswa kugadzira nzira yekufambisa nekudzora ndege, senge gyroscope uye giya rekutungamirira. Yayo yakakwirira magineti uye corrosion kuramba inoita kuti ive sarudzo yakanaka.

Mukupedzisa, nekuda kweiyo yakakosha makemikari kuumbwa uye yakanakisa maitiro,Rare Earth magineti neodymiuminoita basa rakakosha munzvimbo dzakasiyana dzekushandisa, kunyanya mumakina emagetsi, acoustic midziyo, zvekurapa uye indasitiri yezvemhepo. Izvo zvakakoshawo kuve nechokwadi chekuita uye hupenyu hweNeodymium special shaped magineti, dzora kushanduka kwayo kwekushisa uye kutora matanho akakodzera ekudzivirira-corrosion.

Ⅱ. Hunhu uye Kushandiswa kweHematite magineti:

A. Hunhu hweHematite magineti:

Kemikari yakagadzirwa:Hematite magineti inonyanya kuumbwa nesimbi ore, iyo ine iron oxide uye kumwe kusvibiswa. Chimiro chayo chikuru chemakemikari ndeye Fe3O4, iyo inonzi iron oxide.

Magnetism: Hematite magineti ine mwero magineti uye ndeye isina simba remagineti zvinhu. Kana yekunze magineti iripo, Hematite magineti anoburitsa magineti uye anogona kukwezva mamwe magineti zvinhu.

Coercivity: Hematite magineti ine yakaderera Coercivity, ndiko kuti, inoda diki rekunze remagineti kuti riite magineti. Izvi zvinoita kuti Hematite magineti achinjike uye nyore kushanda mune mamwe maapplication.

Corrosion resistance: Hematite magineti yakagadzikana munzvimbo yakaoma, asi inowanzoita ngura munzvimbo ine mvura kana ine hunyoro. Naizvozvo, mune mamwe maapplication, magineti eHematite anoda kurapwa kwepamusoro kana kupeta kuti awedzere kusagadzikana kwavo kwekuora.

B. Kushandiswa kwemagineti eHematite

Traditional magineti zvinhu: Hematite magineti anowanzo shandiswa kugadzira echinyakare magineti zvinhu, senge magineti efiriji, magineti stickers, nezvimwe. Nekuda kwegineti ine mwero uye yakaderera Kumanikidza, Hematite magineti ari nyore kushambadzwa pamusoro pesimbi kana zvimwe zvinhu zvemagineti, uye anogona. kushandiswa kugadzirisa zvinhu, tishu zvinhu uye mamwe maapplication.

Zvombo zvekuchengetedza data:Hematite magineti zvakare ine mamwe maapplication mumidziyo yekuchengetedza data. Semuenzaniso, mune hard disk drives, Hematite magineti anoshandiswa kugadzira magineti akaturikidzana pane dhisiki yepamusoro kuchengetedza data.

Medical imaging equipment: Hematite magineti anoshandiswawo zvakanyanya mumidziyo yekufungidzira yekurapa, senge magineti resonance imaging (MRI) masisitimu. Hematite magineti inogona kushandiswa seiyo magineti jenareta muMRI system kugadzira uye kudzora magineti, nekudaro kuona kufungidzira kwematishu evanhu.

Mhedziso: Hematite magineti ine mwero magineti, yakaderera Kumanikidza uye kumwe kuramba kwecorrosion. Iyo ine yakafara mashandisirwo echinyakare magineti ekugadzira zvinhu, data kuchengetedza zvishandiso, uye yekurapa imaging. Nekudaro, nekuda kwekudzikiswa kwemagnetism uye kuita kwayo, Hematite magineti haana kukodzera kune mamwe maapplication anoda yakakwirira magineti uye kuita zvinodiwa.

Pane misiyano iripachena pakati peNeodymium magineti neHematite magineti mukuumbwa kwemakemikari, magineti zvivakwa uye minda yekushandisa.Neodymium magineti inoumbwa neodymium nesimbi, ine magineti yakasimba uye yakakwirira Coercivity. Inoshandiswa zvakanyanya muminda senge magineti drive zvishandiso, magineti, magineti mabuckles, uye yakakwirira-inoshanda mota. Nekuti Neodymium magineti inogona kuburitsa yakasimba magineti, inogona kushandura simba remagetsi uye simba, inopa inoshanda magineti, uye kuvandudza simba uye kugona kwemota.Hematite magineti inonyanya kuumbwa nesimbi ore, uye chikamu chikuru iFe3O4. Iine mwero magineti uye yakaderera Coercivity. Hematite magineti anoshandiswa zvakanyanya mukugadzirwa kwechinyakare magineti uye mimwe michina yekufungidzira yekurapa. Nekudaro, iyo corrosion resistance yeHematite magineti ishoma, uye kurapwa kwepamusoro kana kupeta kunodiwa kuti vawedzere kusimba kwavo.

Kupfupisa, pane misiyano pakati peNeodymium magineti neHematite magineti mukuumbwa kwemakemikari, magineti zvivakwa uye minda yekushandisa. Neodymium magineti inoshanda kuminda inoda yakasimba magineti uye yakakwirira Coercivity, nepo Hematite magineti inoshanda kune yechinyakare magineti kugadzira uye mimwe michina yekufungidzira yekurapa.Kana uchida kutengacountersunk neodymium mukombe magineti, ndapota taura nesu ASAP.Fekitari yedu ine zvakawandacountersunk neodymium magineti ari kutengeswa.
