Emulsifiers, tseem hu ua emulsifying cov neeg ua haujlwm pab txhawm rau txhim kho lub emulsion los ntawm kev txo qhov cuam tshuam ntawm lub ntsej muag lossis lub zog saum npoo ntawm ob lub kua ua lub emulsion los ntawm kev tsim ib zaj duab xis ntawm nruab nrab thiab tshem tawm cov khoom. Emulsifying cov neeg ua haujlwm yog cov saw hlau ntev nrog cov pawg polar.
Yuav ua li cas tus neeg sawv cev emulsifying tuaj yeem txhim kho qhov ruaj khov ntawm emulsion?
Emulsion tuaj yeem ruaj khov los ntawm nce qhov kev tawm tsam ntawm cov theem tawg piv txwv li, los ntawm kev ua kom cov electrostatic repulsion (uas yog qhov ntev) los yog steric repulsion (ntu luv).
Yuav ua li cas emulsifying cov neeg ua haujlwm ruaj khov ntawm emulsion muab piv txwv ntawm emulsifier rau cov roj hauv dej?
Surfactants adsorb ntawm interface ntawm cov roj thiab dej, yog li txo qhov nro ntawm qhov chaw. Ib qho emulsifier yog ib qho surfactant uas stabilizes emulsions. Emulsifiers lub tsho tiv no cov tee dej hauv ib qho emulsion thiab tiv thaiv kom tsis txhob tuaj ua ke, lossis coalescing.
Yuav ua li cas emulsifying cov neeg ua haujlwm hauv emulsion?
Emulsions ruaj khov los ntawm kev ntxiv cov emulsifier lossis emulsifying tus neeg sawv cev. Cov tshuaj no muaj ob qho tib si hydrophilic thiab lipophilic ib feem hauv lawv cov qauv tshuaj. … Ntxiv rau qhov kev tiv thaiv no, emulsifiers stabilize lub emulsion los ntawm kev txo cov kev sib tshuam ntawm lub cev.
Vim li cas emulsifying tus neeg sawv cev siv hauv emulsion?
Ib tug emulsifying tus neeg sawv cev (emulsifier) yog cov khoom xyaw ntog uasadsorbs ntawm cov tshiab tsim cov roj-dej interface thaum lub sij hawm npaj emulsion, thiab nws tiv thaiv cov tee tsim tshiab tawm tsam tam sim recoalescence.

Yog cov haujlwm tshwj xeeb ua haujlwm ruaj khov?
Cov neeg ua haujlwm hauv Cov Kev Pabcuam Tshwj Xeeb raug muab tso rau hauv pawg neeg ua haujlwm hauv qab no: a. Tenure Group I - Cov neeg ua haujlwm tas mus li uas Cov Kev Teem Sijhawm Tshwj Xeeb yog tsis muaj kev txwvlossis tsis tas yuav ua haujlwm rau lub sijhawm sim.
Vim li cas cov kev ua haujlwm ruaj khov tseem ceeb?
Core stability yog hais txog muaj peev xwm ua kom koj tus txha nraub qaum tsis txav thaum lub cev ua si, xws li taug kev, khiav, ua luam dej, thiab lwm yam. Koj lub hauv paus yuav pab koj tswj koj lub cev zoo, pab koj siv koj ob txhais caj npab thiab txhais ceg kom zoo tshaj plaws thiab tiv thaiv koj tus txha nraub qaum los ntawm kev khoov los yog flexing unintentionally.
