Muketani yekugadzira yeiyo mitsva yemidziyo yekuchengetedza simba yakadai saLithium - ion uye sodium - Ion mabhatiri ebhatiri slurry idanho rinokosha mukusarudza kuita kwechigadzirwa chekupedzisira. Battery slurry ine musanganiswa wezvinhu zvinoshanda, vamiririri vemugove, minda, uye solvent mune yakatarwa huwandu. Yayo yunifomu yekupararira uye foam - zvivakwa zvemahara zvine hukama zvakananga nemhando yeiyo electrode inovhara. Kuvapo kwemabubble mune slurry kunogona kutungamira kuremara senge mapini uye kuunganidza magetsi e eleetrode. Nzira dzechinyakare dzinodzvinyirira, dzakadai seVacuum defoaming uye nekuwedzera kwemakemikari defoamers, zvingave zvisina basa uye simba - zvakadzama, kana kuunza kusvibiswa kunobata kuita kwebhatiri. Kupesana neiyi kumashure, Ultrasonic tekinoroji, neushamwari hwezvakatipoteredza, uye zero yechipiri kusvibiswa, rave mhinduro yekutsvaira yebhatiri inotsemuka.
Ii. Nheyo yepakati yeiyo ultrasonic bhatiri slurry defoaming
Ultrasonic defoaming tekinoroji inokonzeresa mikana yemisangano yehuku uye yekuvandudzwa kwekubvisa zvinobudirira kubvisa mabhuruku mune bhatiri slurry. Nheyo dzayo dzinotaura dzinogona kukamurwa kuita matatu kiyi maitiro:
1. Cavation Atter: "Micro - Kuputika" Bubble Kuparadza
Kana mafungu ekupedzisira (kazhinji ane frequency of 20khz - 1mhz) anoiswa kune bhatiri system, vanogadzira nguva yekumanikidza yekudzvinyirira mukati mechisimba pakati pekumanikidza uye zvisingaverengeki zvikamu. Munguva yekusagadzikana chikamu, kumanikidzwa kuri kuita slurry inodonha zvakanyanya, kugadzira huwandu hukuru hwechidiki wechidiki webasa (cavitation bubbles). Aya mabhuruku mabhuruku anokurumidza kutora bubbles Pashure pacho, panguva yekumanikidza chikamu, kudzvinyirirwa kuri mukutsvedza nekukurumidza zvinomuka. Pasi pekumanikidzwa, iyo mabhuruku inobhururuka ichikurumidza uye inokatyamadza, inounza maCocient International (kusvika zviuru zvematanho) uye nekumisikidza Iyi "micro - Kuputika" - SEZVINONZE KUKOSHESA ZVINOGONESA ZVINOGONESWA BUBBBEBBED BUBBLES MUCHINYANYA BUBBLE NULILI. Aya nuclei, ari mudiki kwazvo kuti arambe akasimba, anokurumidza kubatanidza neakapoteredzwa netara kana kutiza kubva kuhurongwa, kuzadzisa kufungidzira.
2. Vibration kutapurirana: yakatungamirwa bubble kutama uye kupukunyuka
Kana Ultrasound Vaparidzi kuburikidza neSlurry, iyo zvakare inosimudzira - frequency vibraties mumamolekora uye zvimedu mukati meiyo slurry (iyo nguva yekufambisa inoenderana neiyo learthsound frequency). Iyi vibration inokanganisa iyo yakaenzana kuenzana kwemabubble mukati meiyo slurry. Bubbles yakambosungirirwa pamusoro peiyo inoshambidzika zvinyorwa zvekushandisa kana "yakasungwa" neViscossity's Visetic simba pasi pechiitiko, kutyora kubva kune yavo yekubatanidza mapoinzi uye kutama kwakananga kushoma. Kupfuurirazve, kushungurudzika kunoderedza zvevasangano veko kweiyo slurry, kuderedza kupokana neBubble kutama uye kukurumidza kuunganidzwa uye kupukunyuka. Iyi vibration - yakabatsira kutama maitiro yakanyanya kukosha kune yakakwirira - viscosity bhatiri slurries (yakadai lithium - ion bhatiri cathode slurries, iyo kazhinji ine viscosity ye 1000 - 5000mpa)). Inogona kuita zvinobudirira dambudziko re bubble kupukunyuka kubva kumusoro - viscosity slurries panguva yechinyakare vacuum defoam.
3. Kupararira Kwese: Kudzivirira Bubble Kuziviswa
Kusiyana nemakemikari defoamers, ultrasonic tekinoroji kwete chete dens chete asiwo sekondari inopararira zvidimbu zviri mu slurry. Iyo Ultrasonic vibration uye yekuvandudza kuputsa chero zvinyorwa zvinoshanda uye kuitisa mumiririri anounganidza mu slurry, kugadzira imwe yekupararira yunifomu. Kupararira uku kunoderedza iyo "Voids" yakaumbwa neyakagarisana. Aya voids anogona nyore kutambudza mweya uye gadzira bubbles nyowani. Iyo yunifomu yekupararira kwezvidimbu inozadza voidhi iyi, ichidzora mukana wechizvarwa chechipiri bubble pane sosi. Izvi zvinogumisa mikana ye "kuparadzaniswa + kwakadzikira.
III. Zvakaringana zvakanakira zve Ultrasonic defoaming tekinoroji
Kuenzaniswa netsika dzechinyakare dzinodzvinyirira.
1. Yakanyanya kuderera kushanda uye yakashanda yakashanda
Ultrasonic defoaming ine nguva pfupi (kazhinji kurapwa kamwe chete kwemaminitsi mashoma kusvika pamaminitsi anodiwa kuti vaendekete. Kunyangwe yakaderera - viscosity anode slurry (yakadai segreshite slurry for lithindes yakanyanya kuita seyakaoma uye prussian chena Zvinoshanda zvinoshandiswa kubva zana kusvika ku100,000 MPA · 2.
Ultrasonic defoaming nzira yekushomeka kwemuviri isingade yemakemikari emagetsi emagetsi ekuzvidza, anokoshesa kudzivisa kukanganisa kwakashata kwekudzvinyirira mumiririri webhatiri. Izvo zvinhu zveganda mune zvetsika zvemakemikari zvemagetsi zvinogona kuita neElectrode zvinoshanda zvinhu kana kuora panguva yebhatiri, kugadzira magasi uye kutungamira kusvibiswa. Ultrasonic tekinoroji, kune rumwe rutivi, chete mumuviri kupwanya mabhuruku pasina kudzvanywa kwemakemikari weiyo slurry, nekudaro kuwedzera iyo electrochemical uye yekuchengetedza kuita kwebhatiri. Uyezve, iyi tekinoroji inoburitsa isina kutambisa kana kupedza gasi, kuenderana ne "Green Kugadzira" Uzivi uzivi hwendiri idzva resipenzi.
3. Kuita kwakasimba kuwirirana uye nyore kubatanidzwa mumitsara yekugadzira
Iyo Ultrasonic inodonha michina inokonzeresa uye inogona kuve yakasarudzika yakabatanidzwa mune iripo bhatiri slurry gadziriro yekugadzira mitsara yekugadzira. Inogona kushandiswa seyamira yakasvibiswa unit, yakaiswa pakati peiyo slurry kusanganisa tangi uye muchina wekubatanidza. Inogona zvakare kusanganiswa neyakasanganiswa mudziyo kuumba yakabatanidzwa "kusanganisa + Ultrasonic defoaming" System, inogonesa panguva imwe chete yekugadzirira uye defoaming. Uyezve, ultrasonic midziyo paramita (senge frequency, simba, uye nguva yekugadzirisa) inogona kugadziriswa

Panyaya yenguva refu - term yekubhadhara mari, ultrasonic defoams inodya simba kupfuura dzimba dzekupfeka (dzinoda kuwedzera simba rakawanda), uye inobvisa mari yekuchengetera uye kuwedzera mari yemakemikari emagetsi. Panyaya yekugadzira kugadzirwa, ultrasonic defoaming inopa iyo yakagadzikana yekufungidzira maitiro, isingakanganiswe nekutsvedza batch kusiyana uye shanduko mune ambient tembiricha uye humidity. Izvi zvinoderedza iyo electrode scap rate yakakonzerwa nekudzvanywa isina kukwana, kuvandudza gohwo uye kugadzikana kwemutsara wekugadzira. Data rekushandisa kubva kune vamwe vagadziri vebhatiri vanoratidza kuti kushandiswa kweiyo Ultrasonide tekinoroji yePinhole Kuremara
