Cia peb pib
6.Vim li cas neodymium hlau nplaum kim?
Neodymium hlau nplaum kuj kim dua piv rau lwm hom hlau nplaum vim yog ob peb yam:
Cov ntaub ntawv tsis tshua muaj hauv ntiaj teb: Neodymium yog ib qho ntawm lub ntiaj teb tsis tshua muaj, uas tsis tshua pom muaj nyob hauv lub ntiaj teb pob zeb. Kev khawb thiab ua cov ntaub ntawv no yuav kim, thiab cov khoom siv tsawg tsawg tuaj yeem ua rau tus nqi nce.
Cov txheej txheem tsim khoom: Cov txheej txheem tsim khoom rau cov hlau nplaum neodymium yog qhov nyuaj thiab koom nrog ntau cov kauj ruam, suav nrog kev sib tsoo cov ntaub ntawv raw, milling, nias, thiab sintering. Cov txheej txheem no xav tau cov cuab yeej tshwj xeeb thiab kev txawj ntse, uas tuaj yeem ntxiv rau tus nqi.
Kev thov siab: Neodymium hlau nplaum yog nyob rau hauv kev thov siab vim lawv cov khoom tshwj xeeb, xws li lawv lub zog thiab me me. Qhov kev thov siab no tuaj yeem ua rau tus nqi nce ntxiv, tshwj xeeb tshaj yog thaum lub sijhawm muaj kev cuam tshuam ntawm cov khoom lag luam lossis kev xav tau thoob ntiaj teb.
NdFeB ntau lawm ntws
7.Yuav ua li cas ntxuav neodymium hlau nplaum spheres?
Txhawm rau ntxuav neodymium hlau nplaum spheres, koj tuaj yeem ua raws li cov kauj ruam yooj yim no:
1. Sib tov me me ntawm xab npum me me nrog dej sov hauv lub tais lossis dab dej.
2. Muab cov hlau nplaum neodymium spheres rau hauv cov dej soapy thiab cia lawv tsau rau ob peb feeb.
3. Maj mam txhuam qhov saum npoo ntawm lub spheres nrog txhuam txhuam los yog daim ntaub kom tshem tawm cov av lossis cov khib nyiab.
4. Yaug cov spheres kom huv si kom tshem tau cov xab npum seem.
5.Dry cov spheres nrog ib daim ntaub huv si, mos.
Nco tseg: Tsis txhob siv cov tshuaj hnyav lossis cov khoom siv abrasive los ntxuav cov hlau nplaum neodymium, vim qhov no tuaj yeem ua rau lub ntsej muag ntawm lub ntsej muag thiab cuam tshuam rau lawv cov khoom sib nqus. Tsis tas li ntawd, nco ntsoov tuav cov hlau nplaum neodymium ua tib zoo, vim tias lawv nkig thiab tuaj yeem tawg yooj yim los yog tawg yog tias poob los yog mishandled.
8.Yuav ua li cas thiaj nrhiav tau qib ntawm cov hlau nplaum neodymium?
Txhawm rau nrhiav qib ntawm cov hlau nplaum neodymium, koj tuaj yeem nrhiav tau cov lej luam tawm lossis kos rau ntawm cov hlau nplaum nws tus kheej. Cov cai no feem ntau muaj kev sib xyaw ntawm cov lej thiab cov tsiaj ntawv uas qhia lub zog thiab muaj pes tsawg leeg ntawm cov hlau nplaum. Nov yog cov kauj ruam los nrhiav qib ntawm neodymium hlau nplaum:
Nrhiav ib tus lej ntawm cov hlau nplaum. Cov cai no feem ntau yog luam tawm lossis stamped rau ntawm ib qho ntawm qhov chaw tiaj tus ntawm cov hlau nplaum.
Cov lej feem ntau yuav suav nrog cov ntawv thiab cov lej, xws li "N52" lossis "N35EH".
Thawj tsab ntawv lossis cov ntawv sau qhia txog cov khoom siv ntawm cov hlau nplaum. Piv txwv li, "N" sawv cev rau neodymium, thaum "Sm" sawv cev rau samarium cobalt.
Tus lej uas ua raws li thawj tsab ntawv lossis cov ntawv sau qhia txog lub zog siab tshaj plaws ntawm cov hlau nplaum, uas yog qhov ntsuas ntawm nws lub zog. Tus lej siab dua, cov hlau nplaum muaj zog dua.
Qee zaum yuav muaj cov tsiaj ntawv ntxiv lossis cov lej tom kawg ntawm cov lej, uas tuaj yeem qhia lwm yam khoom ntawm cov hlau nplaum, xws li nws qhov kub thiab txias tsis kam.
Yog tias tsis muaj txoj hauv kev los nrhiav cov qib ntawm cov hlau nplaum neodymium koj tuaj yeem nrhiav tau los ntawm kev xeem. Qhov no yog vim qib ntawm cov hlau nplaum neodymium sib txawv los ntawm kev ua haujlwm ntawm cov hlau nplaum neodymium. Koj tuaj yeem siv lub ntsuas gauss los ntsuas qhov saum npoo ntawm cov hlau nplaum neodymium thiab tom qab ntawd siv lub rooj los txiav txim siab qib ntawm cov hlau nplaum neodymium.
9.Puas muaj kev txwv loj npaum li cas cov hlau nplaum neodymium tuaj yeem ua tau?
Tsis muaj kev txwv nyuaj rau qhov loj npaum li cas ntawm cov hlau nplaum neodymium tuaj yeem ua tau, tab sis muaj cov kev txwv uas tau txiav txim siab los ntawm ob peb yam.
Ib qho tseem ceeb yog qhov muaj cov ntaub ntawv tsawg hauv ntiaj teb siv los ua cov hlau nplaum neodymium. Cov ntaub ntawv no tsis tshua pom muaj nyob rau hauv lub ntiaj teb crust thiab yog kim rau kuv thiab txheej txheem. Raws li qhov loj ntawm cov hlau nplaum nce, yog li cov khoom siv xav tau, uas tuaj yeem ua rau cov hlau nplaum loj txwv tsis pub kim.
Lwm qhov tseem ceeb yog cov txheej txheem tsim khoom. Kev tsim cov hlau nplaum neodymium muaj ob peb kauj ruam, suav nrog kev sib tsoo cov ntaub ntawv raw, milling, nias, thiab sintering. Cov txheej txheem no yuav tsum tau siv cov cuab yeej tshwj xeeb thiab kev txawj ntse, uas tuaj yeem nyuaj thiab kim dua rau cov hlau nplaum loj dua.
Neodymium hlau nplaum kuj tuaj yeem ua tau loj heev
Tsis tas li ntawd, cov hlau nplaum neodymium loj dua tuaj yeem ua rau nyuaj dua thiab ua rau muaj kev nyab xeeb vim lawv cov hlau nplaum muaj zog. Lawv kuj tuaj yeem ua rau tawg lossis tawg vim lawv cov brittleness.
Cov hlau nplaum neodymium yog tsim los ntawm kev sib xyaw ntawm neodymium, hlau thiab boron hmoov, uas txhais tau hais tias kev faib cov neodymium hauv cov hlau nplaum neodymium tsis zoo ib yam, thiab nws yog ib qho nyuaj los xyuas kom meej tias cov hlau nplaum ntawm neodymium hlau nplaum yog tib lub zog txhua qhov chaw. . Yog li ntawd, cov hlau nplaum neodymium loj dua feem ntau kim heev los xyuas kom meej qhov ua tau zoo.
0.Yog neodymium muaj zog sib nqus hauv nws daim ntawv ntshiab?
Neodymium los ntawm nws tus kheej tsis muaj zog sib nqus, vim nws yog cov hlau tsis tshua muaj hauv ntiaj teb nrog cov cuab yeej paramagnetic, txhais tau tias nws tsis muaj zog txaus nyiam rau cov hlau nplaum. Txawm li cas los xij, thaum neodymium ua ke nrog lwm cov ntsiab lus xws li hlau thiab boron los tsim cov hlau nplaum Nd2Fe14B, uas yog siv los tsim cov hlau nplaum neodymium, cov khoom sib xyaw ua ke nthuav tawm cov khoom sib nqus muaj zog heev vim qhov sib txawv ntawm nws cov atomic magnetic moments. Lub neodymium nyob rau hauv lub alloy plays lub luag haujlwm tseem ceeb hauv kev txhawb nqa lub zog sib nqus hlau nplaum ntawm neodymium hlau nplaum.
Ib qho piv txwv zoo ntawm qhov no yog qhovlauj kaub hlau nplaum. Lub lauj kaub hlau nplaum muaj peb ntu: lub nplhaib muab lub nplhaib, lub tsev hlau thiab cov hlau nplaum neodymium. Lub luag haujlwm tseem ceeb ntawm lub nplhaib yas yog kho cov hlau nplaum neodymium, yog li nws muaj peev xwm ua tau yam tsis muaj lub nplhaib tuav lub nplhaib kom txuag tau tus nqi raws li cov neeg siv khoom xav tau. Qhov laj thawj tseem ceeb vim li cas lub lauj kaub hlau nplaum muaj cov hlau nplaum yog rau ob qho laj thawj: 1. cov hlau nplaum neodymium tsis yooj yim thiab cov hlau casing tuaj yeem tiv thaiv nws mus rau qee qhov thiab ua rau lub neej ntawm lub lauj kaub hlau nplaum; 2. cov hlau nplaum neodymium thiab cov hlau casing ua ke tuaj yeem tsim cov hlau nplaum muaj zog.
Tswv yim: Tsis txhob kwv yees xws li lub lauj kaub me me, nws yog cov hlau nplaum ntau tshaj li qhov koj xav tau.
