Ultrasonic Dispersion Equipment nyob rau hauv lub roj teeb cheeb tsam
May 30, 2022
Lub dispersion thiab stabilization mechanism ntawm lithium roj teeb slurry, raws li lub zog hom ntawm hais nyob rau hauv lub slurry, lub ntsiab txoj kev kom ua tau zoo dispersion ntawm lithium roj teeb slurry muaj xws li: mechanical dispersion (los yog lub cev dispersion), ultrasonic dispersion thiab tshuaj dispersion (dispersing tus neeg saib xyuas. ). dispersion) nyob rau hauv peb txoj kev. Mechanical dispersion yog ib qho yooj yim lub cev dispersion. Nws tsuas yog siv lub zog siv hluav taws xob xws li sab nraud shear quab yuam lossis kev cuam tshuam lub zog los rhuav tshem cov adhesion ntawm cov khoom, kom cov hmoov nplej tau tawg tag nrho hauv nruab nrab. Mechanical dispersion yog tam sim no feem ntau siv txoj kev dispersion. Ultrasonic dispersion yog tso ncaj qha rau hauv lub roj teeb slurry yuav tsum tau kho nyob rau hauv ib tug ultrasonic teb, thiab siv ultrasonic tsis ntawm tsim nyog zaus thiab lub hwj chim rau cov txheej txheem slurry. Lub hauv paus ntsiab lus ntawm ultrasonic dispersion muaj feem xyuam rau cov nyhuv cavitation. Lub zog saum npoo ntawm cov hmoov hmoov yog tsis muaj zog nyob rau hauv qhov kev txiav txim ntawm kev cuam tshuam loj heev thiab micro-jet, uas tuaj yeem tiv thaiv particle agglomeration. Yog li ntawd, ultrasonic dispersion yog ib txoj kev muaj zog dispersion. Tshuaj dispersion siv cov adsorption ntawm inorganic dispersants ntawm particle nto, uas tsis tsuas yog ho nce lub Zeta peev xwm ntawm particle nto, tab sis kuj tsim ib tug muaj zog steric hindrance nyhuv, kom cov hais nyob rau hauv lub slurry yog uniformly dispersed.
Lub roj teeb colloidal ultrasonic dispersing thiab pouring ntaus ntawv yog siv los ua cov colloid tusyees dispersed nyob rau hauv lub roj teeb, thiaj li yuav xyuas kom meej qhov zoo ntawm cov tsim roj teeb yog ruaj khov thiab tus pass tus nqi siab. Nyob rau tib lub sijhawm, nws tsis cuam tshuam rau kev ua haujlwm ntawm cov khoom siv thaum ua kom cov khoom zoo. Txhawm rau daws cov teeb meem saum toj no, cov qauv siv hluav taws xob tau paub los ntawm cov kev daws teeb meem hauv qab no: lub roj teeb colloidal ultrasonic dispersion kua nplaum filling tshuab, suav nrog lub tshuab nqus tsev acid ntxiv, lub roj teeb uas yuav tsum tau ua tiav yog muab tso rau ntawm lub rooj ua haujlwm ntawm lub tshuab nqus tsev acid. ntxiv tshuab, thiab lub roj teeb yog tig rau lub tshuab nqus tsev acid ntxiv. Cov kua qaub ntawm lub tshuab yog nruab nrog lub tshuab hluav taws xob ultrasonic hauv qab lub roj teeb. Nrog rau cov qauv no, cov colloid nyob rau hauv lub roj teeb tuaj yeem ua ultrasonically dispersed los ntawm lub tshuab hluav taws xob ultrasonic thaum ntxiv kua qaub. Piv nrog rau cov kos duab ua ntej, cov qauv siv hluav taws xob muaj qhov zoo ntawm dispersing cov colloid nyob rau hauv lub roj teeb los ntawm ultrasonic dispersing kauj ruam, tsis txhob muaj teeb meem ntawm cov roj teeb tsis ruaj tsis khov thiab tsis tshua muaj txiaj ntsig vim qhov tsis sib xws ntawm cov colloid dispersion, thiab ua rau tus nqi tsim nyog ntawm cov khoom siv. cov khoom tiav siab.
