Kev ntxuav cov nyhuv ntawm surfactants yog cov yam ntxwv tseem ceeb uas muab cov surfactants zoo tshaj plaws siv. Nws koom nrog lub neej niaj hnub ntawm ntau txhiab tsev neeg. Thiab nws kuj tau siv ntau zuj zus hauv kev lag luam thiab kev lag luam ntau lawm.

Kev ntxuav kom qhuav yog ib txoj kev ntxuav hauv cov kuab tshuaj organic, uas siv cov kuab tshuaj solubility thiab solubility ntawm surfactants kom tshem tawm cov av ntawm cov ntaub. Nws qhov zoo dua yog tias nws tuaj yeem tiv thaiv tsis tuaj yeem thim rov qab ntawm cov ntaub plaub thiab cov ntaub lo lo ntxhuav los ntawm kev ntxuav, nrog rau deformation thiab tsis zoo txhais tes ntawm cov khaub ncaws.

 

Cov av ntawm cov ntaub tuaj yeem muab faib ua peb hom: roj soluble, dej-soluble, thiab roj thiab dej insoluble.

Roj soluble av tuaj yeem raug tshem tawm ncaj qha nrog cov kuab tshuaj organic. Cov kuab tshuaj uas siv tau rau kev ntxuav yog cov roj av hydrocarbons, feem ntau yog tsim los ntawm aliphatic hydrocarbons xws li 1,3-diethylcyclohexane, cycloaliphatic hydrocarbons, thiab 1,2,4-trimethylphenylaromatic hydrocarbons. Tsis tas li ntawd, kuj muaj carbon tetrachloride, trichloroethylene, tetrachloroethylene, thiab lwm yam.

Txhawm rau tshem tawm cov av nrog cov dej zoo solubility lossis muaj zog hydrophilicity, cov dej me me thiab cov surfactants yuav tsum tau ntxiv rau hauv lub cev. Qhov sib ntxiv ntawm surfactants tuaj yeem tiv thaiv kom tsis txhob rov tso cov av hauv cov kuab tshuaj. Lub dispersion stability thiab kev ncua ntawm cov av nyob rau hauv cov organic media tsis yog nyob ntawm seb lub electrostatic repulsion ntawm hais, tab sis tej zaum yuav txiav txim los ntawm adsorption ntawm surfactants ntawm cov khoom-kua interface.

Surfactants nyob rau hauv cov organic media adsorb rau ntawm cov khoom nto li polar pawg, nrog lipophilic hydrocarbon chains taw qhia rau lub xeev adsorption ntawm cov organic solvents thiab adsorbed ntawm cov khoom-kua interface. Qhov no tuaj yeem tsim cov yeeb yaj kiab kev daws teeb meem ntawm cov pa roj carbon hydrogen chains rau ntawm qhov chaw ntawm cov av, tsim kom muaj lub zog tiv thaiv kev cuam tshuam rau qhov chaw thiab tiv thaiv cov tsub zuj zuj lossis rov tso cov av ntawm cov ntaub. Lub xub ntiag ntawm cov dej me me tuaj yeem ua rau hydration ntawm cov khoom thiab cov khoom siv, ua rau lawv yooj yim rau kev cuam tshuam nrog cov pawg polar ntawm surfactants, uas yog qhov zoo rau cov adsorption ntawm surfactants ntawm cov khoom (tshwj xeeb tshaj yog feem ntau polar nto). Qhov no muaj txiaj ntsig zoo rau kev txhim kho kev ntxhua khaub ncaws. Tsis tas li ntawd, thaum surfactants tsim rov qab micelles hauv cov kuab tshuaj organic, cov dej me me thiab nws cov dej-soluble av feem ntau yaj nyob rau hauv rov qab micelles tib lub sijhawm.

 

Surfactants siv rau qhuav tu yuav tsum ua raws li cov hauv qab no:

① Nws yuav tsum muaj peev xwm yaj hauv cov kuab tshuaj ntxuav thiab tsim cov micelles rov qab, thiab muaj peev xwm txaus ntxiv cov dej soluble tuaj yeem tshem tawm cov av zoo thiab muab kev cuam tshuam zoo hauv cov kuab tshuaj organic;
③ Tsawg residual adsorption ntawm ntxhua khaub ncaws thiab lim;
④ Tsis muaj ntxhiab tsw, tsis muaj kev phom sij rau kev ntxhua khaub ncaws, tsis muaj corrosiveness rau hlau, thiab lwm yam.

Surfactants siv rau qhuav tu yuav tsum yooj yim soluble nyob rau hauv cov organic media.

 

Cov uas nquag siv muaj xws li:

① Anionic surfactants xws li roj av sulfonate, sodium alkylbenzenesulfonate (los yog amine ntsev), thiab sodium succinate sulfonate;

② Tsis yog ionic surfactants xws li polyoxyethylene alkyl cawv ethers, polyoxyethylene alkyl phenols, polyoxyethylene alkyl amides, thiab lwm yam.
