Txhawm rau muab cov nplais sib xyaw zoo, cov khoom siv sib xyaw xav tau tsib yam!
Aug 30, 2020
Kev npaj ntawm lub electrode slurry yog qhov tseem ceeb tshaj plaws ntawm tag nrho cov txheej txheem, thiab qhov zoo ntawm cov electrode slurry ncaj qha cuam tshuam seb nws tuaj yeem mus rau kauj ruam tom ntej. Kev npaj zom zaws yog qhov tsis yog-Newtonian high-viscosity kua tsim los ntawm kev sib xyaw nrog cov tshuaj, cov nplaum, cov kuab tshuaj, cov tuab tuab thiab lwm cov hmoov. Cov kua dej yuav tsum muaj qee lub viscosity, zoo fluidity thiab txaus cov khoom tawg me me. Yog tias tus neeg ua haujlwm xav ua nws txoj haujlwm zoo, nws yuav tsum xub ntse nws cov cuab yeej. Dab tsi ntawm cov khoom siv uas yuav tsum tau ua rau kev npaj cov electrode slurry kom tau raws li qhov yuav tsum tau ua?
1. Lub peev xwm tau loj txaus
Kev tsim cov roj teeb yuav tsum tau muaj ntau daim ncej thiab yuav tsum muaj kev cuam tshuam zoo dua ntawm cov hlwb. Qhov no yuav tsum tau hais tias lub slurry xav tau qee yam sib xws. Hauv cov txheej txheem sib tov sib xyaw, cov slurry hauv txhua lub lauj kaub tsis yog tib yam vim kev sib xyaw ua ke, lub sijhawm thiab kev txiav txim ntxiv. Txawm hais tias nyob rau hauv cov txheej txheem ib yam, cov slurry Cov viscosity tsis tas yuav zoo ib yam. Yog li no, tus tov yuav tsum muaj qee yam peev xwm. Tam sim no, tov ntau teev tau tuaj yeem ua tiav 2000L. Thaum lub peev xwm loj txaus, lub peev xwm sib xyaw thiab cov khoom sib xyaw ua ke ntawm cov khoom yuav tsum raug txiav txim siab.
2. Muaj lub tshuab nqus tsev zoo nruj
Cov khoom sib xyaw xav tau lub tshuab nqus tsev zoo kaw. Muaj peb lub laj thawj:
Thaum lub sij hawm tag nrho cov txheej txheem sib xyaw, vim muaj kev sib tsoo thiab cov kev sib txhuam ntawm cov khoom siv, thiab kev sib txhuam ntawm tus nplawm thiab cov khoom siv, cov cua sov ntau yuav tsim tawm thiab qhov kub yuav nce. Qhov nce hauv qhov kub thiab txias yuav ua rau qee cov kuab tshuaj ua kom tawm thiab tsim kom muaj ntxhiab ntxhiab heev, xws li NMP, PVDF, thiab lwm yam. Cov pa roj av muaj teeb meem ntau rau tib neeg lub cev.
②Nyob rau hauv cov hmoov qhuav premixing theem, yog tias lub kaw lus kaw tsis zoo tsis txaus, nws yuav ua rau muaj plua plav paug, ua rau thaj chaw ua haujlwm tsis zoo, cuam tshuam rau cov khoom lag luam zoo thiab tsim kev puas tsuaj rau cov neeg ua haujlwm.
Tej muaj voids loj hauv cov hmoov. Tom qab sib tov nrog cov kuab tshuaj, muaj qhov khi kom muaj ntau lub npuas hauv cov slurry. Lub slurry xav tau defoamed ua ntej tus ncej ncej yog coated. Txwv tsis pub, cov npuas yuav tawg thaum txheej txheem txheej, qhov chaw ntawm lub npoo yuav txawv, lossis txawm tias ntawv ci yuav raug nthuav tawm, uas yog qhov cuam tshuam rau kev ua tau zoo ntawm lub roj teeb.
3. Cov khoom siv ntawm cov khoom tov muaj muaj zog tiv thaiv corrosion, hnav tsis kam thiab ruaj khov lub cev thiab tshuaj
Pom tseeb, tsis hais txog qhov muaj zog alkalinity ntawm cov khoom siv zoo electrode, qhov muaj zog corrosiveness ntawm NMP, thiab lwm yam, cov khoom sib xyaw yuav tsum muaj kev txhim kho zoo corrosion. Thaum lub sijhawm txheej txheem sib tov, kev sib xyaw tsis tu ncua ntawm cov hmoov los ntawm tus agitator yuav tsum kom nws muaj kev txhim kho xeb thiab muaj kev pab lub neej ntev.
4. lub tshuab nqus hniav qauv yog tsim nyog, thiab kev sib xyaw nrawm tsim tau raws li qhov yuav tsum tau ua
Ntxiv rau kev sib xyaw ua kom muaj zog txaus thiab ntau yam sib xyaw rau hauv cov tov khoom, cov duab thiab cov qauv siv tshuab ntawm cov tshuab tov khoom muaj lub zog loj rau kev npaj slurry. Ua ntej tshaj plaws, nws yuav tsum tau ua kom paub tseeb tias qhov sib xyaw ntawm cov kab kev sib tsoo muaj qhov loj txaus thiab tsis muaj ib lub ces kaum rau hauv lub thawv sib xyaw. Nyob rau tam sim no, dual-ncej los yog txawm peb-lub ntiaj teb cov cav tov sib xyaw yog siv rau hauv cov khoom sib xyaw loj dua kom ntseeg tau tias tsis muaj hmoov los yog agglomerated cov khoom siv tsis tseem sib xyaw rau hauv cov slurry. Thib ob, tus qauv tsim ntawm cov agitator muaj qhov cuam tshuam zoo tshaj plaws rau cov khoom tawg, sib xyaw, kev faib tawm me me, npliag npliag, thiab lwm yam. Cov hom duab tam sim no nyob rau hauv kev ua lag luam suav nrog hom duav, hom npauj npaim, hom thauj tog rau nkoj, ntswj hom, khawm rau tes, hom thav duab, thiab lwm yam. lawv, Yog li nws yog tsim nyog. Qhov thib peb xav tau yog tias cov khoom siv muaj qhov nrawm nrawm uas ua tau raws li qhov yuav tsum ua kom tau raws li qhov xav tau ntawm cov roj molecular hnyav thiab ultrafine hmoov dispersion.
Ntxiv nrog rau tus tsim ntawm lub ntsiab sib xyaw ua ke thiab cov nqaj, qee cov khoom siv muaj cov qauv scraper thiab lub taub ntim kev sib hloov tsim los txhim kho cov kev ua tau zoo thiab cov khoom sib xyaw ntau yam.
5. Kev nyab xeeb ntawm kev tov khoom
Kev tsim kev nyab xeeb ntawm kev tov khoom yuav tsum tsim nyog, suav nrog cov khoom tawg-pov thawj tsim, cov cuab yeej kev nyab xeeb nres nres tsim thiab ruaj khov ntawm cov cuab yeej, kom tsis txhob raug mob rau tus neeg teb xov tooj.
Qhov saum toj no yog cov kev xav tau yooj yim rau lithium roj teeb slurry npaj khoom siv, thiab kev hloov pauv coj ua yuav tsum tau ua raws li cov khoom cov khoom sib txawv.
