Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub pob zeb zoo ib yam: Lub nruas rotating tso cai rau cov khoom sib tsoo kom poob rau hauv lub ntiajteb txawj nqus thiab cuam tshuam cov qauv, ua tiav crushing thiab sib tov. Txawm li cas los xij, nws muaj lub zog ua haujlwm tsawg, lub sijhawm sib tsoo ntev, thiab nyuaj rau kev ua cov khoom siv ultrafine.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub pob zeb planetary: Los ntawm kev txav ntawm lub ntiaj teb (lub nruas revolves nyob ib ncig ntawm lub ntsiab ncej thaum tig ntawm nws tus kheej axis), siab - kev sib tsoo thiab shear quab yuam yog tsim los ntawm cov khoom sib tsoo thiab cov qauv hauv qab centrifugal quab yuam. Qhov no concentrates thiab tso tawm lub zog, uas ua rau ib tug exponential nce nyob rau hauv kev sib tsoo efficiency.
Tsis tas li ntawd, planetary pob zeb yog cov cuab yeej tseem ceeb rau kev txhim kho kev ua tau zoo ntawm tag nrho -khoom-state lithium roj teeb: Tag nrho cov-khoom- lub xeev cov roj teeb siv cov khoom siv hluav taws xob-state electrodes thiab khoom-state electrolytes. Cov khoom siv hluav taws xob zoo ntawm cov khoom siv- lub xeev cov roj teeb tsis sib txawv ntawm cov roj ntsha electrolyte, thaum cov khoom siv hluav taws xob tsis zoo feem ntau yog siv cov roj ntsha lithium, lithium alloys, lossis silicon-raws li cov electrode tsis zoo. Tsis zoo li cov kua lithium{10}} ion roj teeb, cov roj teeb muaj zog- lub xeev siv cov khoom siv hluav taws xob siv cov kua electrolyte thiab cov khoom sib cais. Lub hauv paus ntawm cov khoom siv{13}} lub xeev cov roj teeb yog nyob rau hauv kev tsim cov khoom electrolytes nrog cov khoom siv tshuab siab, siab ionic conductivity, zoo heev electrochemical thiab thermal stability, thiab compatibility nrog cov ntaub ntawv electrode. Pob milling tshuab feem ntau yog siv los tsim cov khoom siv electrolytes los ua cov khoom siv electrolyte thiab txhim kho kev ua haujlwm ntawm tag nrho cov{15}}khoom- lub xeev roj teeb.
Ib txoj haujlwm uas yuav siv lub pob zeb zoo li 10 teev kom tiav tuaj yeem ua tiav hauv 4-5 teev, lossis tsawg dua, los ntawm lub pob zeb planetary!
Txoj Cai Sib Tsoo ntawm Planetary Pob Zeb
Thaum lub sij hawm sib tsoo txheej txheem nyob rau hauv lub planetary pob zeb, cov khoom yog pulverized los ntawm kev cuam tshuam, compression, thiab kev sib txhuam ntawm cov khoom sib tsoo. Qhov tseeb, cov txheej txheem pulverization yog qhov nyuaj heev. Kawm txog ib qho me me, nws tau rov ua dua qhov kev ntxhov siab uas tau hais los saum no thaum lub pob zeb milling, ua rau cov kab nrib pleb uas twb muaj lawm lossis tshiab tsim nyob rau hauv cov khoom kom nthuav dav, ua rau tawg lossis yas deformation.
Raws li cov khoom me me, cov kab nrib pleb ntawm lawv ua zoo dua, txo qhov tshwm sim ntawm cov kab nrib pleb ntawm qhov tsawg kawg nkaus kev ntxhov siab. Kev sib tsoo quab yuam nce mus rau qhov chaw uas cov khoom ua rau cov yas deformation, ua rau kev sib tsoo nyuaj ntxiv thaum qee qhov me me mus txog. Yog li ntawd, lub pob milling ntev ntev yog qhov tsis muaj qab hau thiab tsuas yog ua kom muaj zog siv zog vim tias cov khoom siv ultrafine tsis tuaj yeem khaws cov elastic zog uas yuav tsum tau ua rau kev tawg.
Qhov tseeb, lub ntsiab lus ntawm kev sib tsoo ntawm lub ntiaj teb pob zeb yog tam sim no tsuas yog to taub los ntawm kev sim xav lossis kev xav. Cov txheej txheem pob zeb tiag tiag yog qhov nyuaj ntau dua li tau piav qhia saum toj no. Kev sib tsoo ntawm cov khoom sib txawv vim muaj kev sib cuam tshuam ntawm cov khoom, nruab nrab ntawm cov khoom thiab cov thawv sib tsoo, nruab nrab ntawm cov khoom thiab cov khoom sib tsoo, thiab cov tshuaj sib cuam tshuam ntawm cov khoom.
Peb qhov zoo ntawm cov pob zeb planetary pob zeb:
Ob chav zog ceev: Lub centrifugal acceleration ntawm planetary motion tuaj yeem ncav cuag 20-40g (piv rau 1g hauv cov pob zeb zoo tib yam), uas ua rau muaj kev sib tsoo pob kinetic zog, yooj yim crushing nanoscale nyuaj cov ntaub ntawv (xws li silicon carbide thiab ceramics).
Ntau- txoj kev sib tsoo qhov sib txawv: Tsis zoo li cov pob zeb sib xyaw ua ke uas cov pob sib tsoo ua raws li ib qho kev sib tw, cov pob zeb planetary siv lub zog centrifugal thiab cov tshuaj tiv thaiv kev sib hloov los tsim cov kev sib tw peb- qhov kev txav mus los, ua tiav kev sib tsoo tsis muaj lub kaum ntse ntse tuag.
Kev tswj qhov kub thiab txias: Qee qhov siab -kawg planetary pob mills tau nruab nrog lub tshuab ua kom txias kom tsis txhob muaj cua sov decomposition ntawm cov qauv thaum lub sijhawm ua haujlwm ntev (cov paib pob zeb feem ntau raug yuam kom kaw vim muaj cua sov).
ACEY-VHBM-2Lplanetary pob milling tshuabyog engineered rau ntau yam qauv ua, txhawb kev sib tsoo qhuav, ntub sib tsoo hauv kev ncua, thiab ua haujlwm nyob rau hauv inert gas tej yam kev mob. Ntxiv rau qhov ua tau zoo particle txo qhov loj me, nws ua kom muaj kev sib xyaw ua ke thiab homogenization ntawm emulsions thiab pastes, nrog rau kev sib xyaw ua ke thiab ua kom muaj zog rau kev tshawb fawb cov khoom siv siab heev. Tsim los ua compact tab sis ua haujlwm tau zoo, lub kaw lus ua kom muaj txiaj ntsig zoo thiab ua haujlwm ntsiag to. Nws ua haujlwm zoo tshaj plaws rau kev tshawb fawb qauv npaj hauv kev kawm, chaw ua haujlwm, thiab chaw soj nstuam, nrog lub peev xwm los ua plaub yam qauv sib txawv hauv ib pawg.
