Taw qhia rau cov khoom siv hlau nplaum muaj zog
Cov ntaub ntawv muaj zog sib nqus, tshwj xeeb tshaj yog cov khoom siv hlau nplaum ruaj khov xws li neodymium hlau boron (NdFeB) thiab samarium cobalt (SmCo), tau siv dav hauv kev lag luam niaj hnub vim lawv cov hlau nplaum muaj zog thiab kev ua haujlwm zoo heev. Los ntawm cov motors mus rau cov khoom siv kho mob, los ntawm cov neeg siv khoom siv hluav taws xob mus rau aerospace, cov ntaub ntawv no ua lub luag haujlwm tseem ceeb. Txawm hais tias cov khoom siv hlau nplaum muaj zog siv hauv ntau qhov chaw, lawv qhov kev phom sij tsis tuaj yeem tsis quav ntsej. Cia peb kawm paub tias cov khoom siv hlau nplaum muaj zog npaum li cas, nkag siab zoo dua cov kev pheej hmoo, thiab tiv thaiv lawv zoo dua.
Cov khoom siv hlau nplaum muaj zog npaum li cas yug
1. Raw khoom npaj: Thawj kauj ruam hauv kev tsim cov khoom siv hlau nplaum muaj zog yog npaj cov khoom siv raw. Rau NdFeB, cov ntaub ntawv tseem ceeb suav nrog neodymium, hlau, boron thiab lwm yam kab kawm xws li dysprosium thiab praseodymium. Cov ntaub ntawv raw yuav tsum tau soj ntsuam nruj me ntsis thiab ua tiav kom ntseeg tau tias qhov purity thiab muaj pes tsawg leeg ua tau raws li qhov yuav tsum tau ua.
2. Melting: Cov ntaub ntawv npaj tau muab tso rau hauv lub tshuab nqus tsev induction rau melting los ua ib qho alloy. Hauv cov txheej txheem no, kev tswj qhov kub thiab txias yog qhov tseem ceeb heev thiab feem ntau yuav tsum tau ua ntawm qhov kub siab tshaj 1000 ° C. Cov smelted alloy kua yuav muab nchuav rau hauv pwm kom txias thiab tsim ib qho ingot.
3.Crushing thiab sib tsoo: Lub ingot txias yuav tsum tau tawg mus rau hauv me me los ntawm ib tug crusher thiab tom qab ntawd ntxiv hauv av rau hauv hmoov zoo los ntawm lub pob zeb. Qhov loj me me ntawm cov hmoov zoo ncaj qha cuam tshuam qhov zoo ntawm cov txheej txheem tom ntej, yog li cov kauj ruam no tseem ceeb heev.
4. Orientation nias: Cov hmoov zoo yog loaded rau hauv pwm thiab ces taw qhia thiab nias nyob rau hauv qhov kev txiav txim ntawm ib tug muaj zog magnetic teb. Qhov no ua kom ntseeg tau tias cov kev taw qhia ntawm cov khoom sib nqus ntawm cov hmoov sib nqus zoo ib yam, yog li txhim kho cov khoom sib nqus ntawm cov khoom kawg. Cov khoom tom qab oriented nias yog hu ua "ntsuab lub cev".
5. Sintering: Lub cev ntsuab yog muab tso rau hauv lub qhov cub sintering thiab sintered ntawm qhov kub thiab txias (kwv yees li 1000 ° C-1100 ° C) kom khov thiab tsim cov hlau nplaum ntom ntom. Thaum lub sij hawm sintering txheej txheem, cov ntaub ntawv undergoes complex lub cev thiab tshuaj hloov, thiab thaum kawg tsim ib tug tiav cov khoom uas muaj siab magnetic zog.
6. Kev ua thiab kev kho deg: Cov hlau nplaum sintered kuj yuav tsum tau txiav, polished thiab lwm yam kev ua haujlwm kom ua tiav cov duab thiab qhov loj me. Txhawm rau tiv thaiv cov hlau nplaum los ntawm oxidation lossis corrosion thaum siv, txheej tiv thaiv xws li npib tsib xee, zinc lossis epoxy resin feem ntau yog coated rau ntawm nws qhov chaw.
7. Magnetization: Cov kauj ruam kawg yog ua kom cov hlau nplaum kom muab cov khoom sib nqus uas yuav tsum tau muaj. Magnetization feem ntau yog ua los ntawm cov khoom siv hlau nplaum tshwj xeeb, siv cov hlau nplaum muaj zog ua kom cov hlau nplaum sib nqus hauv cov hlau nplaum sib xws.
Kev puas tsuaj ntawm cov hlau nplaum muaj zog
Lub lethality ntawm cov khoom sib nqus muaj zog yog qhov tseem ceeb hauv cov hauv qab no:
1. Kev cuam tshuam rau cov khoom siv hluav taws xob: Cov khoom siv hlau nplaum muaj zog tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob, tshwj xeeb tshaj yog cov uas cia siab rau cov khoom sib nqus. Piv txwv li, cov xov tooj ntawm tes, khoos phis tawj hard drives, credit cards, thiab lwm yam yuav raug cuam tshuam los ntawm cov hlau nplaum muaj zog, ua rau cov ntaub ntawv poob lossis cov khoom puas.
2.Kev cuam tshuam rau tib neeg lub cev: Txawm hais tias cov khoom siv hlau nplaum muaj zog tsis ua rau muaj kev phom sij rau tib neeg lub cev, lawv tuaj yeem ua rau mob hauv zos lossis tsis xis nyob yog tias nqos lossis tiv nrog daim tawv nqaij. Tsis tas li ntawd, cov khoom siv hlau nplaum muaj zog kuj tseem tuaj yeem nyiam cov khoom hlau nyob ze thiab ua rau raug mob.
3.Kev cuam tshuam rau lwm yam khoom sib nqus: Cov khoom siv hlau nplaum muaj zog tuaj yeem nyiam thiab txav mus rau lwm cov khoom sib nqus, uas yuav ua rau cov khoom hnyav poob lossis cov khoom siv puas yog tias tsis ua haujlwm zoo. Yog li ntawd, thaum siv cov khoom sib nqus muaj zog, kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua kom tsis txhob muaj kev pheej hmoo tsis tsim nyog.
4.Kev cuam tshuam rau cov cuab yeej siv tshuab: Qee zaum, cov khoom siv hlau nplaum muaj zog tuaj yeem nqus cov hlau hauv cov cuab yeej siv tshuab, ua rau cov khoom siv tsis ua haujlwm lossis kaw. Cov nyhuv no tshwj xeeb tshaj yog nyob rau hauv cov cuab yeej precision thiab cov cuab yeej kho mob.
Yuav ua li cas tiv thaiv cov teebmeem ntawm cov hlau nplaum muaj zog
1. Khaws koj qhov deb: Khaws cov khoom sib nqus muaj zog kom deb ntawm cov khoom siv hluav taws xob, credit cards thiab lwm yam khoom rhiab heev.
2. Kev tiv thaiv: Hnav cov cuab yeej tiv thaiv tsim nyog thaum tuav cov khoom sib nqus muaj zog thiab tsis txhob sib cuag nrog daim tawv nqaij.
3. Kev kawm thiab lus ceeb toom: Qhia cov me nyuam kom tsis txhob ua si nrog cov khoom ua si sib nqus muaj zog thiab xyuas kom lawv nkag siab txog qhov muaj kev phom sij.
4. Kev cob qhia kws tshaj lij: Nyob rau hauv ib puag ncig kev kho mob, xyuas kom cov neeg mob thiab cov neeg ua haujlwm nkag siab txog kev nyab xeeb ntawm cov khoom siv hlau nplaum uas muaj zog thiab siv cov kev tiv thaiv tsim nyog.
5. Kev khaws cia thiab kev thauj mus los: Cov khoom siv hlau nplaum muaj zog yuav tsum muab khaws cia rau hauv cov thawv tshwj xeeb thiab tiv thaiv kom zoo thaum lub sijhawm thauj mus los kom tsis txhob muaj kev sib cuag nrog lwm yam khoom.
Cov txheej txheem tsim khoom ntawm cov khoom siv hlau nplaum muaj zog yog cov txheej txheem nyuaj thiab muag heev uas muaj ntau cov kauj ruam thiab cov txuj ci kev tshaj lij. Kev nkag siab txog nws cov txheej txheem tsim khoom pab peb nkag siab zoo dua thiab siv cov ntaub ntawv no. Nyob rau tib lub sijhawm, peb kuj yuav tsum paub txog qhov muaj peev xwm txaus ntshai ntawm cov khoom siv hlau nplaum muaj zog thiab siv cov kev tiv thaiv zoo los xyuas kom peb muaj kev nyab xeeb.
