Rare Earth Magnets tau siv txhua hnub, Tab sis lawv yog dab tsi?

Neodymium Iron Boron Rare Earth Magnets tau siv txhua qhov chaw thiab yog ib qho ntawm cov hlau nplaum ruaj khov tshaj plaws muaj. Tab sis lawv yog dab tsi?
Neodymium Magnet (tseem hu ua NdFeB, NIB lossis Neomagnet) yog hom siv dav tshaj plaws ntawm Rare Earth Magnet. Nws yog cov hlau nplaum ruaj khov uas tau tsim los ntawm cov hlau nplaum ntawm neodymium, hlau thiab boron los tsim Nd2Fe14B tetragonal crystalline qauv.
Thawj Neodymium Magnet tau pom nyob rau xyoo 1982 los ntawm General Motors thiab Sumitomo Cov Hlau Tshwj Xeeb thaum lawv tshawb nrhiav lwm txoj hauv kev rau Samarium Cobalt Magnets kim. Txij li thaum qhov kev tshawb pom, kev siv Neodymium Magnet tau kov txhua tus neeg lub neej thiab tuaj yeem pom hauv cov khoom uas peb siv niaj hnub xws li xov tooj ntawm tes, khoos phis tawj thiab txawm tias chav ua noj txee dai khaub ncaws. Lawv kuj tseem ceeb rau lub zog tauj dua tshiab xws li cua turbines thiab hluav taws xob
Neodymium Magnets kuj tseem pab peb rov ua dua tshiab raws li qhov tseem ceeb ntawm Magnetic Separator lossis Eddy Current Separator raws li tsim los ntawm Bunting Magnetics. Lub zog sib nqus yog siv rau ob qho tib si nyiam thiab tua cov hlau kom muaj kev sib cais thiab rov qab los.
Tuam Tshoj dominates lub ntiaj teb no zus tau tej cov Neodymium Magnets (95 feem pua) vim qhov chaw ntawm ntau ntawm reserves. Thaum kawg ntawm xyoo 2010 thiab mus rau xyoo 2011, Tsoomfwv Suav tau xa cov kev poob siab thoob plaws ntiaj teb thaum lawv txiav cov quotas export rau Rare Earth Magnets thiab nce nqi rau cov neeg siv khoom txawv teb chaws. Nws tsis yog txog xyoo 2015, tom qab Tuam Tshoj tau poob lub Koom Haum Ntiaj Teb Kev Lag Luam uas tau coj los ntawm Asmeskas thiab lwm tus neeg koom tes ua lag luam, tias cov kev txwv tau so.
Neodymium Magnets yog tsim los ntawm ob txoj kev tsim khoom:
• Classical hmoov metallurgy los yog sintered hlau nplaum txheej txheem;
• Ceev ceev solidification los yog bonded hlau nplaum txheej txheem;
Cov txheej txheem Sintered hlau nplaum tsim kom muaj zog thiab tsis tshua muaj Lub Ntiaj Teb Magnet, tab sis kim dua los tsim.
Muaj ntau qhov ntau thiab tsawg thiab cov duab ntawm Neodymium Magnets rau ntau hom kev siv uas txuas ntxiv mus. Tsis muaj kev poob qis hauv qhov kev thov thiab tsuas yog cov lus nug ntawm cov khoom siv thiab tus nqi nyob rau lub sijhawm ntev.
