tus neeg sawv cev nto M31

piav qhia luv luv:

Emulsifier yog ib hom tshuaj uas ua rau ob lossis ntau yam khoom sib xyaw ua ke ua ib qho emulsion ruaj khov. Nws lub hauv paus ntsiab lus yog thaum lub sijhawm emulsion, theem dispersed ua cov droplets (microns) dispersed hauv theem tas mus li, nws txo qhov kev sib txhuam ntawm txhua yam khoom hauv lub cev sib xyaw, thiab qhov chaw droplet los ua ib zaj duab xis khov kho lossis vim muaj kev them nyiaj ntawm emulsifier hauv qhov chaw droplet tsim ob txheej hluav taws xob, tiv thaiv cov droplets sib sau ua ke, thiab kom cov emulsion sib xws. Los ntawm qhov pom ntawm theem, cov emulsion tseem heterogeneous. Theem dispersed hauv emulsion tuaj yeem yog theem dej lossis theem roj, feem ntau yog theem roj. Theem tas mus li tuaj yeem yog roj lossis dej, thiab feem ntau ntawm lawv yog dej. Emulsifier yog ib qho surfactant nrog pawg hydrophilic thiab pawg lipophilic hauv molecule. Txhawm rau qhia txog cov khoom hydrophilic lossis lipophilic ntawm emulsifier, "hydrophilic lipophilic equilibrium value (HLB value)" feem ntau yog siv. Tus nqi HLB qis dua, qhov muaj zog ntawm cov khoom lipophilic ntawm emulsifier. Ntawm qhov tsis sib xws, tus nqi HLB siab dua, qhov muaj zog ntawm hydrophilicity. Ntau yam emulsifiers muaj cov nqi HLB sib txawv. Yuav kom tau txais cov emulsions ruaj khov, yuav tsum xaiv cov emulsifiers tsim nyog.
