1.Wetting action (Required HLB: 7-9)
Kev ntub dej yog hais txog qhov tshwm sim uas cov roj adsorbed ntawm cov khoom nto yog hloov los ntawm cov kua. Cov khoom uas txhim khu lub peev xwm hloov pauv no hu ua wetting agents.Wetting feem ntau muab faib ua peb hom: hu rau wetting (adhesion wetting), immersion wetting (kev nkag mus rau wetting), thiab kis wetting (kis).
Ntawm cov no, kev sib kis yog tus qauv siab tshaj plaws ntawm kev ntub dej, thiab kev sib kis coefficient feem ntau yog siv los ua qhov taw qhia ntawm kev ua haujlwm ntub dej ntawm cov tshuab.
Tsis tas li ntawd, lub kaum sab xis ntawm kev sib cuag kuj yog ib qho kev ntsuas rau kev soj ntsuam kev ua haujlwm ntawm wetting.
Kev siv cov surfactants tuaj yeem tswj qhov ntub dej ntawm cov kua thiab cov khib nyiab.
Hauv kev lag luam tshuaj tua kab, qee cov granules thiab hmoov rau txau muaj qee qhov nyiaj ntawm surfactants. Lawv lub hom phiaj yog txhawm rau txhim kho qhov adhesion thiab tso tawm ntawm tus neeg sawv cev ntawm qhov chaw kho, txhim kho tus nqi tso tawm thiab nthuav dav thaj tsam ntawm cov khoom xyaw nquag hauv cov dej noo, thiab txhim kho kev tiv thaiv kab mob thiab kev tiv thaiv.
Hauv kev lag luam tshuaj pleev ib ce, ua ib qho emulsifier, nws yog ib qho tseem ceeb ntawm cov khoom tu tawv nqaij xws li cream, lotions, cleansers, thiab pleev tshem tawm.
2.Foaming thiab defoaming ua
Surfactants kuj tau siv dav hauv kev lag luam kws tshuaj. Nyob rau hauv cov tshuaj formulations, ntau yam tsis zoo soluble tshuaj xws li volatile roj, fat-soluble cellulose, thiab steroidal cov tshuaj hormones tuaj yeem tsim cov kev daws teeb meem kom meej thiab nce concentration los ntawm solubilizing kev txiav txim ntawm surfactants.
Thaum lub sij hawm kev npaj tshuaj, surfactants yog indispensable raws li emulsifiers, wetting agents, suspending agents, foaming agents, thiab defoaming agents.Foam muaj roj los ntawm ib tug nyias kua zaj duab xis. Qee cov surfactants tuaj yeem tsim cov yeeb yaj kiab ntawm qee lub zog nrog dej, npog huab cua los ua npuas dej, uas yog siv hauv cov ntxhia flotation, ua npuas dej tua hluav taws, thiab ntxuav. Cov tshuaj no hu ua foaming agents.
Qee zaum defoamers xav tau. Hauv kev ua qab zib refining thiab tshuaj suav tshuaj suav tshuaj, ntau ua npuas ncauj tuaj yeem ua teeb meem. Ntxiv cov surfactants tsim nyog txo cov yeeb yaj kiab, tshem tawm cov npuas, thiab tiv thaiv kev raug mob.
3.Suspending action (Ncua tseg stabilization)
Hauv kev lag luam tshuaj tua kab, cov hmoov ntub dej, emulsifiable concentrates, thiab concentrated emulsions tag nrho yuav tsum muaj qee qhov nyiaj ntawm surfactants.Vim ntau cov khoom xyaw hauv cov hmoov ntub dej yog hydrophobic organic compounds, surfactants yog xav tau los txo cov dej saum npoo nro, ua kom cov dej ntub dej ntawm cov tshuaj thiab tsim cov aqueous suspensions.
Surfactants yog siv nyob rau hauv cov ntxhia flotation kom ua tiav kev ncua kev ruaj ntseg. Los ntawm nplawm thiab bubbling cua los ntawm hauv qab ntawm lub tank, npuas nqa zoo ntxhia hmoov sib sau ua ke ntawm qhov chaw, uas lawv tau sau thiab defoamed rau concentration, ua tiav enrichment.Xuab zeb, av nkos, thiab pob zeb tsis muaj minerals nyob hauv qab thiab raug tshem tawm ib ntus.
Thaum 5% ntawm cov ntxhia xuab zeb saum npoo yog npog los ntawm ib tus neeg sau, nws dhau los ua hydrophobic thiab txuas rau npuas, nce mus rau saum npoo rau kev sau.Cov khoom tsim nyog tau xaiv yog li nws cov pawg hydrophilic tsuas yog ua raws li cov ntxhia xuab zeb nto thaum pawg hydrophobic ntsib cov dej.
4.Disinfection thiab sterilization
Hauv kev lag luam kws tshuaj, surfactants tuaj yeem siv los ua cov kab mob thiab tshuaj tua kab mob. Lawv cov tshuaj tua kab mob thiab ua kom tsis muaj menyuam ua rau muaj kev cuam tshuam zoo nrog cov kab mob biofilm proteins, ua rau denaturation lossis tsis ua haujlwm.
Cov tshuaj tua kab mob no muaj siab solubility hauv dej thiab tuaj yeem siv ntau qhov sib txawv rau:
· Tshuaj tua kab mob ua ntej daim tawv nqaij
· Tshuaj tua kab mob los yog mucosal
· Cov cuab yeej sterilization
· Environmental tshuaj tua kab mob
5.Detergency thiab ntxuav kev txiav txim
Tshem tawm cov roj stains yog txheej txheem nyuaj uas cuam tshuam nrog cov lus hais saum toj no, ua npuas dej, thiab lwm yam kev ua.
Detergents feem ntau muaj ntau yam pab cuam rau:
· Txhim kho qhov ntub dej ntawm cov khoom raug ntxuav
· Ua npuas ncauj
· Muab cov teebmeem brightening
· Tiv thaiv kom tsis txhob rov ua av
· Cov txheej txheem ntxuav ntawm surfactants ua cov khoom tseem ceeb ua haujlwm raws li hauv qab no:
Dej muaj cov npoo siab nro thiab tsis zoo ntub dej muaj peev xwm tshem tawm cov pab pawg thiab cov nplais hydrophobic rau cov nplais thiab adsorbed av, maj mam ua rau cov paug tsis sib thooj. Cov av tseem raug tshem tawm hauv dej los yog ntab rau saum npoo nrog ua npuas dej ua ntej raug tshem tawm, thaum lub ntsej muag huv si ua coated nrog surfactant molecules.
Thaum kawg, nws yuav tsum raug sau tseg tias surfactants ua haujlwm tsis yog los ntawm ib qho kev ua haujlwm tab sis feem ntau los ntawm kev sib xyaw ua ke ntawm ntau yam.
Piv txwv li, hauv kev lag luam ntawv, lawv tuaj yeem ua haujlwm xws li:
· Cov neeg ua noj ua haus
· Pov tseg daim ntawv de-inking agents
·Sizing tus neeg sawv cev
· Resin obstacles tswj tus neeg saib xyuas
· Defoamers
·Softeners
· Cov tshuaj tiv thaiv kab mob
· Scale inhibitors
· Cov tshuaj Softening
· Cov tshuaj degreasing
· Bactericides thiab algaecides
· Corrosion inhibitors
