Peb cov khoom tseem ceeb: Amino silicone, thaiv silicone, hydrophilic silicone, tag nrho lawv cov silicone emulsion, ntub dej rubbing fastness improver, dej repellent (Fluorine free, Carbon 6, Carbon 8), demin ntxuav tshuaj (ABS, Enzyme, Spandex protector, Manganese Remover),Lub teb chaws xa tawm tseem ceeb: Is Nrias teb, Pakistan, Bangladesh, Türkiye, Indonesia, Uzbekistan, thiab lwm yam
★ Wetting nyhuv
Thaum cov khoom nkag mus rau hauv kev sib cuag nrog cov kua, cov khoom qub / roj thiab cov kua / roj cuam tshuam ploj thiab cov khoom tshiab / kua cuam tshuam tau tsim, uas yog hu ua wetting. Textile fibers yog cov khoom ntxeem tau nrog thaj chaw loj heev. Thaum cov tshuaj sib kis raws cov fibers, nws nkag mus rau qhov sib txawv ntawm cov fibers thiab tsav tawm cov huab cua, tig cov huab cua qub / fiber ntau interface rau hauv cov kua / fiber ntau interface, uas yog cov txheej txheem ntub dej; Thiab cov tshuaj yuav kuj nkag mus rau sab hauv ntawm cov fiber, uas yog hu ua permeation. Surfactants uas pab kom ntub dej thiab permeation yog hu ua wetting agents thiab permeation agents.
★ Cov nyhuv emulsification
Vim lub siab nro ntawm cov roj hauv dej, thaum cov roj poob rau hauv dej thiab nplawm, cov roj yog crushed rau hauv cov hlaws dai zoo thiab sib xyaw ua ke los ua ib qho emulsion, tab sis cov stirring nres thiab cov khaubncaws sab nraud povtseg yog rov txheej. Yog hais tias ib tug surfactant ntxiv thiab nplawm tas li, tab sis nws tsis yooj yim rau kev sib cais ntev ntev tom qab nres, qhov no yog emulsification. Qhov laj thawj yog vim li cas cov roj hydrophobicity nyob ib puag ncig los ntawm cov pab pawg hydrophilic ntawm cov neeg ua haujlwm nquag, tsim cov kev taw qhia kev nyiam thiab txo cov haujlwm uas yuav tsum tau ua rau cov roj dispersion hauv dej, ua rau cov roj emulsification zoo.
★ Ntxuav thiab stain tshem tawm muaj nuj nqi
Vim tias cov nyhuv emulsifying ntawm surfactants, cov roj thiab cov av uas tau muab tshem tawm los ntawm cov khoom nto tuaj yeem ruaj khov emulsified thiab dispersed nyob rau hauv aqueous daws, thiab tsis tso rau ntawm qhov chaw ntxuav kom rov ua pa phem.
★ Suspension dispersion nyhuv
Cov txheej txheem ntawm dispersing insoluble solids rau hauv ib qho kev daws raws li cov khoom me me los ua ib qho kev ncua yog hu ua dispersion. Cov surfactant uas txhim kho cov khoom tawg yooj yim thiab ua kom ruaj khov yog hu ua dispersant. Qhov tseeb, nws yog qhov nyuaj rau kev paub qhov txawv ntawm cov roj semi-solid yog emulsified los yog dispersed nyob rau hauv kev daws thaum lub sij hawm emulsification thiab dispersion txheej txheem, thiab emulsifiers thiab dispersants feem ntau yog tib yam khoom. Yog li ntawd, hauv kev siv tswv yim, ob qho tib si ua ke thiab hu ua emulsifying dispersants.
★ Solubilization nyhuv
Solubilization hais txog cov nyhuv ntawm surfactants ntawm kev ua kom cov solubility ntawm insoluble los yog tsis zoo soluble tshuaj nyob rau hauv dej. Piv txwv li, solubility ntawm benzene nyob rau hauv dej yog 0.09% (ntim feem). Yog hais tias surfactants (xws li sodium oleate) ntxiv, solubility ntawm benzene tuaj yeem nce mus rau 10%.
Cov nyhuv solubilization yog sib cais los ntawm micelles tsim los ntawm surfactants hauv dej. Micelles yog micelles tsim los ntawm hydrophobic kev sib cuam tshuam ntawm carbon thiab hydrogen chains nyob rau hauv surfactant molecules nyob rau hauv aqueous daws. Sab hauv ntawm micelles yog cov kua hydrocarbons tiag tiag, yog li tsis yog-polar organic solutes xws li benzene thiab ntxhia roj uas tsis muaj dej hauv dej yog yooj yim yaj hauv micelles. Solubilization tshwm sim yog cov txheej txheem ntawm micelles dissolving lipophilic tshuaj, uas yog tshwj xeeb ua ntawm surfactants. Yog li ntawd, tsuas yog thaum lub concentration ntawm surfactants nyob rau hauv cov tshuaj yog siab tshaj qhov tseem ceeb micelle concentration, uas yog, thaum muaj ntau loj micelles nyob rau hauv cov tshuaj, solubilization tshwm sim. Tsis tas li ntawd, qhov loj dua qhov ntim ntawm micelles, qhov ntau dua cov nyiaj solubilization.
Solubilization txawv ntawm emulsification. Emulsification yog ib qho kev sib txuas tsis tu ncua thiab tsis ruaj khov uas tau txais los ntawm dispersing ib theem ua kua rau hauv dej (lossis lwm theem ua kua), thaum solubilization tsim ib theem ib homogeneous ruaj khov system uas cov tshuaj solubilizing thiab cov tshuaj solubilized nyob rau tib theem. Qee lub sij hawm tib lub surfactant muaj ob qho tib si emulsifying thiab solubilization teebmeem, tab sis tsuas yog thaum nws cov concentration siab tshaj qhov tseem ceeb micelle concentration, nws puas muaj cov nyhuv solubilization.
★ Mos thiab du
Thaum surfactant molecules yog taw qhia thiab teeb tsa ntawm qhov chaw ntawm cov ntaub, nws tuaj yeem txo cov kev sib txhuam zoo li qub coefficient ntawm cov ntaub. Tsis yog ionic surfactants xws li linear alkyl polyol polyoxyethylene ether thiab linear alkyl fatty acid polyoxyethylene ether, nrog rau ntau yam cationic surfactants, tag nrho cov nyhuv ntawm kev txo cov kev sib txhuam zoo li qub coefficient ntawm fabrics, ua rau lawv haum li ntaub softeners. Surfactants nrog branched alkyl los yog aromatic pab pawg neeg tsis tuaj yeem tsim ib qho kev taw qhia zoo nyob rau saum npoo ntawm cov ntaub, yog li lawv tsis haum rau siv los ua softeners.
