Lub hauv paus ntsiab lus thiab kev ua haujlwm ntawm emulsifying tshuab

1. Txo cov particle loj: vim lub tshuab shear quab yuam ntawm lub siab ceev rotor thiab stator, lub tshuab emulsifying tuaj yeem txo qhov loj ntawm cov khoom sib xyaw hauv cov khoom sib xyaw. Brittle solids, elastomers thiab plastics tuaj yeem ua rau hauv av lossis tawg. Rau cov dyes thiab pigments uas tau ua zoo hauv av, vim lub ntim, kev thauj mus los, stacking, ntxiv rau cov teebmeem ntawm hluav taws xob zoo li qub, av noo thiab lwm yam, yuav muaj qhov tshwm sim ntawm kev sib koom ua ke. Tom qab lub tshuab hloov pauv, nws tuaj yeem ua lub luag haujlwm nrawm nrawm.

2. Dissolution: lub siab shear mixing emulsifier muaj lub luag haujlwm ntawm lub dav hlau shear, uas zoo heev txhim kho cov efficiency ntawm kev sib tov thiab sib tov, yog li nws txhim kho cov solubility. Rau qee cov ntaub ntawv, xws li roj hmab, thaum ntxiv cov kuab tshuaj, lawv yuav agglomerate, uas ua rau nws nyuaj rau yaj. Lub shearing txiav txim ntawm lub tshuab emulsifying tuaj yeem tawg cov tshuaj sai sai thiab txhim kho tus nqi tawg.

3. Dispersion: lub tshuab emulsifying muaj lub ntim ntim loj, uas ua rau cov kua dej ntau dua li cov tshuab sib xyaw ua ke tib lub sijhawm. Yog li ntawd, lub tshuab emulsifying tsis tau tsuas yog muaj lub siab shear npaum li cas, tab sis kuj muaj ib tug siab ncig ntim, thiaj li ua kom lub dispersion ntawm cov ntaub ntawv.

4. Emulsification: vim lub dav hlau ceev shearing, cov khoom muaj zog tearing nyhuv, uas tuaj yeem txo qhov loj ntawm qhov poob mus rau qib zoo heev. Emulsification yog ib qho yooj yim kom ua tiav hauv qhov nruam shearing thiab tearing ntawm cov kua tawg ntawm lub tshuab emulsifying.
