Noj mov Ntub nyhuv

 

Thaum cov khoom nkag mus rau hauv kev sib chwv nrog kua, cov qub khoom siv / roj thiab kua hauv / roj interface tau ploj mus, uas yog hu ua ntub dej. Textile fibers yog cov khoom siv ntxeem tau nrog thaj chaw loj loj. Thaum qhov kev daws teeb meem kis raws cov fibers, nws nkag mus rau hauv cov fibers ntawm cov fibers thiab tsav tawm cov huab cua / fiber cuam tshuam rau hauv cov kua / fiber ntau interface, uas yog ib qho txheej txheem ntub; Thiab kev daws teeb meem tseem yuav nkag mus rau sab hauv ntawm cov fiber ntau, uas yog hu ua permeration. Surfactants uas pab txhawb kev ntub thiab kev ua tau zoo yog hu ua cov neeg sawv cev ntub dej thiab cov neeg sawv cev.

 

Noj mov Emulsification nyhuv

 

Vim yog lub siab nro ntawm cov roj hauv dej, thaum roj tau poob rau hauv dej thiab sib xyaw ua ke los ua ib qho emulsion, tab sis cov khaubncaws sab nraud povtseg, tab sis cov khaubncaws sab nraud pov tseg, tab sis cov khaubncaws sab nraud pov tseg, tab sis cov khaubncaws sab nraud pov tseg, tab sis cov khaubncaws sab nraud povtseg, tab sis cov khaubncaws sab nraud povtseg, tab sis cov khaubncaws sab nraud povtseg, tab sis cov khaubncaws sab nraud povtseg, tab sis cov khaubncaws sab nraud povtseg Yog hais tias ib tug surfactant yog ntxiv thiab do dag zog, tab sis nws tsis yooj yim cais rau lub sijhawm ntev tom qab nres, qhov no yog emulsification. Qhov laj thawj yog tias cov roj hydrophobicity ntawm cov roj yog puag ncig ntawm cov pab pawg hydrophilic

 

Noj mov Ntxuav thiab stain tshem tawm haujlwm

 

Vim yog emulsifying cuam tshuam ntawm surfactants, roj thiab av thiab tsis muaj peev xwm emulsified thiab dispersed nyob rau hauv aqueous colutions, thiab tsis muaj kev tso nyiaj rau cov kev ua qias tuaj.

 

Noj mov Ncua Kev Rho Tawm Tawm

 

Cov txheej txheem ntawm dispersing insoluble cov khoom siv rau hauv kev daws teeb meem yog cov me me los ua kev ncua ntawv yog hu ua dispersion. Lub surfactant uas txhim kho cov kev faib tawm thiab cov ntaub ntawv tsis muaj zog yog hu ua qhov tsis txaus ntseeg. Qhov tseeb, nws yog qhov nyuaj kom paub qhov txawv txawm tias cov roj semi-cov roj yog emipiing lossis dispersion txheej, thiab emiptionifiers thiab dispersarsers thiab dispidants feem ntau yog tib yam khoom. Yog li ntawd, hauv kev siv, ob yog ua ke thiab xa mus ua emulsifying dispersants.

 

Noj mov Solubilization nyhuv

 

Solubilization hais txog cov nyhuv ntawm cov txiaj ntsig ntawm surfactants rau kev nce cov solubility ntawm insoluble lossis tsis zoo soluble tshuaj hauv dej. Piv txwv li, cov solubility ntawm benzene hauv dej yog 0.09% (ntim feem). Yog hais tias surfactants (xws li sodium ingeat) tau ntxiv, cov solubility ntawm Benzene tuaj yeem nce mus rau 10%.

 

Cov nyhuv solubilization yog inseparable los ntawm micelles tsim los ntawm surfactants hauv dej. Micelles yog micelles tsim los ntawm hydrophobic sib cuam tshuam ntawm carbon thiab hydrogen chainsules hauv surfactant molecules hauv cov kev daws teeb meem aqueous. Lub sab hauv micelles yog ua tau ua kua hydrocarbons, yog li cov roj uas tsis muaj roj av zoo li cov roj av thiab cov ntxhia thiab cov ntxhia hauv cov dej yooj yim dua hauv micelles. Solubilization Promomenon yog txheej txheem ntawm Micelles diss discolning lipophilic tshuaj, uas yog qhov tshwj xeeb ntawm surfactants. Yog li ntawd, tsuas yog thaum lub concentration ntawm surfactants hauv kev daws teeb meem yog qhov tseem ceeb tshaj plaws ntawm micelles nyob rau hauv kev daws teeb meem, muaj peev xwm solubilization tshwm sim. Ntxiv mus, qhov loj dua qhov ntim ntawm micelles, ntau dua cov nyiaj solubilization ntau dua.

 

Solubilization yog txawv ntawm emulsification. Emulsification yog qhov tsis txaus siab thiab tsis ruaj khov Multiphase system tau los ntawm dispersing cov kua ua kua rau hauv uas cov kua dej ua kua thiab cov khoom siv solubilized nyob hauv tib theem. Qee lub sij hawm tib surfactant muaj ob leeg emulsifyify thiab solubilization cuam tshuam, tab sis tsuas yog thaum nws qhov tseem ceeb yog qhov tseem ceeb tshaj plaws ntawm lub tswv yim.

 

Noj mov Mos thiab du

 

Thaum surfactant molecules yog taw qhia thiab npaj rau saum npoo ntawm cov ntaub, nws tuaj yeem txo cov txheeb ze ntawm cov ntaub. Tsis ionic surfactants xws li linear alkyl polyol polyol polyox polyoxty ether acid polyoxet ethid polyoxety Surfactants nrog branched alkyl lossis cov pab pawg uas muaj ntxhiab tsis tuaj yeem ua cov khoom siv zoo nkauj ntawm cov ntaub, yog li lawv tsis tsim nyog siv ua cov khoom muag.
