Recycling Neodymium Magnets: Yam Koj Yuav Tsum Paub

Neodymium hlau nplaum, muaj npe nrov rau lawv lub zog tshwj xeeb thiab ntau yam, ua lub luag haujlwm tseem ceeb hauvntau yam kev lag luam, los ntawm electronics mus rau lub zog tauj dua tshiab. Raws li qhov kev thov rau kev coj ua kom ruaj khov txuas ntxiv nce ntxiv, qhov tseem ceeb ntawm cov khoom siv rov ua dua tshiab, suav nrog cov hlau nplaum neodymium, tau tshwm sim ntau ntxiv. Kab lus no tshawb txog qhov tseem ceeb ntawm kev rov ua dua cov hlau nplaum neodymium, ua kom pom kev ntawm cov txheej txheem cuam tshuam thiab cov txiaj ntsig ib puag ncig ntawm lub luag haujlwm pov tseg.

1. Kev sib xyaw thiab cov khoom siv:

Neodymium hlau nplaum yog tsim los ntawm neodymium, hlau, thiab boron, tsim cov hlau nplaum tsis tshua muaj ntiaj teb nrog lub zog tsis sib xws. Kev nkag siab txog qhov muaj pes tsawg leeg ntawm cov hlau nplaum no yog qhov tseem ceeb rau kev rov ua dua tshiab, vim nws tso cai rau kev sib cais ntawm cov ntaub ntawv thaum lub sijhawm rov ua dua.

2. Qhov tseem ceeb ntawm Recycling:

Recycling neodymium hlau nplaum yog qhov tseem ceeb rau ntau yam. Ua ntej, neodymium yog ib qho tsis tshua muaj-lub ntiaj teb, thiab mining thiab ua nws tuaj yeem muaj kev cuam tshuam ib puag ncig. Kev rov ua dua tshiab pab txuag cov peev txheej muaj nuj nqis no thiab txo qhov xav tau kev rho tawm tshiab. Tsis tas li ntawd, lub luag haujlwm pov tseg ntawm cov hlau nplaum neodymium tiv thaiv kev puas tsuaj ib puag ncig los ntawm kev pov tseg cov khoom siv hluav taws xob tsis raug.

3. Kev sau thiab sib cais:

Thawj kauj ruam hauv kev rov ua dua cov hlau nplaum neodymium suav nrog kev sau thiab sib cais ntawm cov ntaub ntawv. Cov txheej txheem no feem ntau tshwm sim thaum lub sij hawm rov ua dua ntawm cov khoom siv hluav taws xob, xws li hard drives, hais lus, thiab cov tshuab hluav taws xob, uas feem ntau siv cov hlau nplaum neodymium. Cov txheej txheem sib nqus sib nqus yog ua haujlwm los cais cov hlau nplaum los ntawm lwm yam khoom.

4. Demagnetization:

Ua ntej ua cov hlau nplaum neodymium, nws yog ib qho tseem ceeb rau demagnetize lawv. Qhov no ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab tiv thaiv kev sib nqus tsis sib xws thaum lub sijhawm rov ua dua tshiab. Demagnetization tuaj yeem ua tiav los ntawm kev nthuav tawm cov hlau nplaum rau qhov kub thiab txias lossis siv cov cuab yeej tshwj xeeb tsim los rau lub hom phiaj no.

5. Sib tsoo thiab sib cais ntawm Cheebtsam:

Thaum demagnetized, neodymium hlau nplaum feem ntau yog hauv av rau hauv cov hmoov los pab txhawb kev sib cais ntawm lawv cov ntsiab lus. Cov kauj ruam no suav nrog kev rhuav tshem cov hlau nplaum rau hauv cov khoom me me rau kev ua haujlwm ntxiv. Cov kev sib cais tom qab, xws li cov txheej txheem tshuaj, pab tshem tawm neodymium, hlau, thiab boron cais.

6. Rov qab ntawm Rare-Earth Elements:

Kev rov qab los ntawm neodymium thiab lwm yam tsis tshua muaj hauv ntiaj teb yog qhov tseem ceeb ntawm cov txheej txheem rov ua dua tshiab. Ntau cov tswv yim, suav nrog cov kuab tshuaj tshem tawm thiab nag lossis daus, yog ua haujlwm los cais thiab ntxuav cov ntsiab lus no, ua rau lawv tsim nyog rau rov siv dua hauv kev tsim cov hlau nplaum tshiab lossis lwm yam kev siv.

7. Cov txiaj ntsig ib puag ncig:

Recycling neodymium hlau nplaum pab txhawb kev txuag ib puag ncig los ntawm kev txo cov kev xav tau ntawm cov khoom siv tshiab, txo qis kev siv hluav taws xob, thiab txo cov khoom pov tseg. Tsis tas li ntawd, kev tuav pov hwm lub luag haujlwm tiv thaiv kev tso tawm cov khoom phom sij uas yuav muaj nyob hauv cov hlau nplaum neodymium thaum ua tsis raug.

8. Kev Lag Luam Initiatives:

Ntau qhov kev lag luam thiab cov tuam txhab lag luam tau lees paub qhov tseem ceeb ntawm cov kev coj ua kom ruaj khov, ua rau cov tswv yim tsim los txhim kho cov khoom siv rov ua dua tshiab ntawm cov hlau nplaum neodymium. Kev sib koom tes ntawm cov tuam txhab tsim khoom, cov khoom siv rov ua dua tshiab, thiab cov neeg tsim txoj cai yog qhov tseem ceeb los tsim lub voj kaw rau cov khoom tseem ceeb no.
