Lub tshuab nqus tsev emulsifiers ua lub luag haujlwm tseem ceeb hauv kev sib xyaw ntawm cov khoom siv hauv kev lag luam, tshwj xeeb tshaj yog hauv cov khoom sib xyaw ua kua, kua-kua sib tov, roj-dej emulsification, dispersion thiab homogenization, shear sib tsoo thiab lwm yam. Qhov laj thawj yog vim li cas nws thiaj li hu ua lub tshuab emulsifying yog vim nws tuaj yeem ua tiav cov nyhuv emulsifying. Roj-dej emulsion yog tsim tom qab ob-theem nruab nrab yog tag nrho tov, thiab muab faib ua ob lub tshuab: dej-hauv-roj los yog dej-hauv-roj. Yuav kom ua tiav emulsification, muaj tsawg kawg yog ob qhov yuav tsum tau ua:
Ua ntej, cov neeg kho tshuab txiav muaj zog dispersing nyhuv. Cov theem dej thiab cov roj theem nyob rau hauv cov kua nruab nrab yog txiav mus rau hauv me me hais nyob rau tib lub sij hawm, thiab ces merged ua ke nyob rau hauv kev sib nrig sib nkag mus thiab sib tov los tsim ib tug emulsion.
Qhov thib ob, qhov tsim nyog emulsifier ua tus neeg nruab nrab ntawm cov roj thiab dej molecules. Los ntawm qhov kev txiav txim ntawm cov nqi hluav taws xob thiab lub zog intermolecular, cov roj-dej sib tov emulsion tuaj yeem khaws cia ruaj khov rau lub sijhawm xav tau.
Lub zog ntawm shearing txiav txim ntawm lub emulsifier ncaj qha cuam tshuam cov fineness. Los ntawm kev tsom xam, feem ntau yog qhov sharpness, hardness, stator qhov sib txawv, tus txheeb ze ceev ntawm ob lub txiav hniav thiab qhov tso cai particle loj, thiab lwm yam. Nyob rau hauv ib txwm muaj teeb meem, lub sharpness thiab hardness ntawm cov hniav, , stator clearance thiab lub hauv paus tso cai. Qhov tseem ceeb yog nyob ntawm qhov loj me me los yog tsis xav hloov, yog li ntawd, qhov txheeb ze ceev ntawm cov hniav yog ib qho tseem ceeb, qhia raws li lub voj voog ceev ntawm lub rotor (vim lub stator nyob ruaj ruaj). Yog tias qhov nrawm dua, qhov ceev ntawm kev txiav los yog impinging radial flow fluid yuav siab dua, yog li cov nyhuv dilution yuav muaj zog, thiab vice versa. Txawm li cas los xij, qhov siab dua ntawm kab nrawm, qhov zoo dua. Thaum nws nce mus txog tus nqi siab heev, muaj lub siab xav nres, yog li qhov ntws los ua me me, cua sov yog siab heev, thiab qee cov khoom siv hauv lem accumulates, ua rau cov txiaj ntsig zoo.
