Lub lim dej hlau nplaum sib nqus ntawm cov hlau tsis xeb daws qhov teeb meem ntawm cov hlau tsis huv ntau dhau.

Keeb Kwm

Ib lub tuam txhab tsim cov tshuaj pleev xim tiv thaiv kev lag luam thiab cov xim pleev xim rau tsheb hauv North America tau ntsib cov xim dub me me rov tshwm sim ntau zaus ntawm lawv cov xim dawb thaum ntxov xyoo 2024. Tom qab kev tshuaj xyuas, nws pom tias muaj cov khoom me me ferromagnetic 5-80 micron thiab cov hmoov carbon impurities, uas ua rau muaj cov khoom me me ntau dhau.

Kev Sib Tw

Lub lim dej qub uas zoo li lub pob tawb tsuas yog ntes tau cov khoom me me uas loj dua 150 micrometers xwb thiab tsis muaj zog tiv thaiv cov hmoov hlau ntawm qib micron. Cov khoom tsis huv los ntawm kev hnav thaum thauj cov khoom siv raw, kev hnav khoom siv, thiab kev xeb ntawm cov yeeb nkab. Qhov zoo tsis ua raws li cov qauv, ua rau muaj kev pheej hmoo ntawm kev poob cov neeg siv khoom loj.

Kev daws teeb meem

Thaum Lub Rau Hli 2024, tus neeg siv khoom tau qhia txog kev caistainless hlau magnetic pas nrig pob tawb lim, kev sib xyaw ua ke 5 10,000 gauss neodymium hlau boron hlau nplaum tas mus li (rau kev nqus cov khoom ferromagnetic) thiab lub pob tawb lim hlau stainless hlau 200-mesh (rau kev cuam tshuam cov khoom tsis muaj hlau nplaum). Lub cev lub tog raj kheej yog ua los ntawm 316L stainless hlau thiab muaj cov qauv tsim clamp sai rau kev saib xyuas yooj yim. Cov khoom siv tau teeb tsa tom qab cov txheej txheem sib tsoo thiab tau teeb tsa hauv kev teeb tsa sib luag nrog ob chav kom ua rau lub tshuab kaw tas mus li rau kev ntxuav.

Cov nyhuv

Kev txo qis ntawm qhov tsis huv: Tus naj npawb ntawm cov khoom ferromagnetic ib kilogram tau txo qis los ntawm ntau dua 200 mus rau tsawg dua 5, thiab cov ntsiab lus hlau ion tau poob qis los ntawm 85 ppm mus rau 12 ppm.
Kev rov qab los ntawm cov neeg siv khoom thiab kev nce ntxiv: Cov neeg siv khoom loj tau rov qab yuav khoom thiab lawv cov xaj txhua xyoo tau nce 10%, tsis muaj kev tsis txaus siab hlo li.
Kev txhim kho kev ua haujlwm zoo: Qhov zaus ntxuav tau raug txo los ntawm ib zaug ib zaug mus rau ib zaug txhua peb hnub, thiab lub sijhawm rau kev ntxuav ib zaug tau raug txo los ntawm 40 feeb mus rau 20 feeb.
Txo tus nqi: Tus nqi txij nkawm tau txo qis mus rau 30% ntawm tus nqi qub.
Kev nthuav dav lag luam: Tus nqi ntawm cov xim pleev xim zoo tau nce 5%, thiab tau txais cov xaj tshiab rau cov txheej txheem aviation.

Tus thawj coj tsim khoom tau hais tias: "Lub lim dej sib nqus no daws cov teeb meem tshuaj siv cov ntsiab cai yooj yim. Nws tsis muaj cov khoom siv lossis kev siv hluav taws xob, thiab pib ua haujlwm tam sim ntawd thaum ntsia."
