Sodium Lauryl Ether Sulfate yog dab tsi?
Sodium lauryl ether sulfate (SLES), tseem hu ua sodium alkyl ether sulfate, yog ib qho anionic surfactant tsim los ntawm ethoxylation thiab tom qab sulfation ntawm fatty alcohols. Cov khoom lag luam feem ntau yog muab los ntawm 70% active aqueous paste, uas yog vim li cas lub npe SLES 70% yog tus qauv hauv kev lag luam. SLES yog tus nqi- ua haujlwm tau zoo thiab muaj txiaj ntsig zoo ua npuas ncauj, thiab nws qhov profile ua rau nws nrov hauv cov neeg siv khoom thiab cov khoom lag luam.
Raws li ib qho anionic surfactant, txhua SLES molecule nqa ib tug tsis zoo nqi hydrophilic lub taub hau pab pawg neeg thiab ib tug ntev hydrophobic Tail. Cov qauv amphiphilic no tso cai rau cov molecule los txo qhov nro ntawm qhov sib cuam tshuam ntawm dej thiab roj lossis av, uas yog lub hauv paus txheej txheem tom qab ntub dej, emulsification, thiab ua npuas ncauj.
Hom Specification Range ntawm SLES 70%
| Parameter | Tus nqi |
|---|---|
| Qhov tshwm sim | Dawb rau lub teeb daj muab tshuaj txhuam |
| 1,4-Dioxane cov ntsiab lus | 30 ppm max |
| Cov ntsiab lus nquag | 68-72 wt% |
| Sodium sulfate | 1.5 wt% max |
| pH tus nqi, 1% tov | 7.0-9.5 |
| Unsulfated teeb meem | 2.0 wt% max |
| Xim, Hazen ntawm 5% active teeb meem | 20 max |
Cov txiaj ntsig no sawv cev rau kev lag luam tshwj xeeb pom zoo ntawm cov neeg tsim khoom thiab cov neeg yuav khoom. Qhov kev txwv 1,4-dioxane yog qhov tseem ceeb tshwj xeeb vim tias 1,4-dioxane yog cov khoom lag luam ntawm cov kauj ruam ethoxylation, thiab ntau cov kev cai qis qis txwv nws cov concentration hauv cov neeg siv khoom tiav.
Sab saum toj Tsib Kev Siv SLES 70%
Tsev thiab Industrial Detergents
SLES 70% yog siv dav hauv kev tsim cov tshuaj ntxuav tais diav, kua ntxhua khaub ncaws, thiab tshuab- ntxhua khaub ncaws. Ua tsaug rau nws lub zog tiv thaiv kab mob zoo heev thiab ua haujlwm rau cov dej tawv, nws yog ib qho zoo tagnrho hloov rau cov tshuaj surfactants xws li linear alkylbenzene sulfonate (LABSA) thiab phosphates, muab ob qho tib si kev ua tau zoo thiab tus nqi -kev ua tau zoo hauv cov khoom siv tu. Hauv kev tu tsev, tib yam khoom txhawb nqa cov tsev ntxhua khaub ncaws, chav ua noj degreasers, thiab dav dav - lub hom phiaj nyuaj - cov tshuaj ntxuav saum npoo.
Cov Khoom Siv Kho Tus Kheej
SLES yog cov khoom tseem ceeb hauv cov tshuaj zawv plaub hau, da dej gel, da dej ua npuas ncauj, thiab ua kua ntxuav tes. Nws txo qhov nro saum npoo thiab xa cov nplua nuj, ruaj khov ua npuas ncauj uas cov neeg siv khoom koom nrog kev ntxuav kom zoo. Nws muaj peev xwm ua tau yooj yim thickened nrog sodium chloride ua rau nws yooj yim tshwj xeeb tshaj yog nyob rau hauv cov tshuaj pleev ib ce, qhov twg viscosity yuav tsum tau tuned precisely. Rau cov plaub hau- daim ntawv thov kev saib xyuas, SLES yog qhov nyiam tshaj qhov hnyav surfactants vim nws qhov kev sib piv tsis tshua muaj peev xwm ua kom khaus, biodegradability zoo, thiab me me surfactant.
Tshuaj txhuam hniav thiab kho qhov ncauj
Vim nws zoo heev emulsification thiab foaming zog, SLES 70% kuj yog siv nyob rau hauv kev tsim cov tshuaj txhuam hniav. Raws li anionic surfactant, nws pab cuam tshuam lwm cov khoom xyaw sib npaug thiab muab cov neeg siv khoom txaus siab xav tau los ntawm cov khoom siv huv hauv qhov ncauj, thaum tswj tsis tshua muaj khaus rau lub qhov muag thiab hauv ob sab phlu ntawm lub qhov ncauj. Formulators sib npaug qib SLES ua tib zoo nrog cov abrasives, humectants, thiab flavors kom ua tiav qhov kev xav tau zoo nkauj thiab kev ua haujlwm tu.
Industrial Cleaning Agents
Hauv kev tu cov khoom xws li degreasing cov neeg ua haujlwm thiab cov tshuaj ntxuav qhov chaw, SLES muaj cov solubility zoo heev, zoo sib xws nrog lwm cov surfactants, thiab kev ua haujlwm ruaj khov hauv cov dej tawv. Cov khoom no ua rau nws tsim nyog rau kev tu cov haujlwm nyuaj hauv ob qho tib si hauv kev lag luam thiab chaw ua haujlwm ib puag ncig, suav nrog zaub mov- cov chaw ua haujlwm, kev saib xyuas kev thauj mus los, thiab hlau- npaj nto. Vim tias SLES yog biodegradable, nws kuj nyiam nyob rau hauv formulations qhov twg ib puag ncig hneev taw yuav tsum tau txo.
Formulation Versatility thiab Eco-Kev phooj ywg
Qhov txiaj ntsig tseem ceeb kawg ntawm SLES yog nws cov qauv tsim muaj ntau yam. Nws cov nyhuv thickening, wetting zog, thiab ua npuas ncauj stability cia nws mus integrate yooj yim mus rau hauv ib tug ntau yam ntawm cov kua xab npum thiab cosmetic systems. Nws tuaj yeem ua ke nrog amphoteric, tsis yog -ionic, thiab cationic co-surfactants kom zoo-tu siab, ua npuas ncauj zoo, thiab ntxuav lub zog. Nyob rau tib lub sijhawm, SLES muaj nuj nqis rau kev ua biodegradable thiab muab cov khaus khaus rau ntawm daim tawv nqaij thiab qhov muag, uas txhawb nqa nws cov khoom siv uas yuav tsum tau ua raws li cov qauv kev ruaj ntseg niaj hnub no.
Kev nyab xeeb thiab kev txiav txim siab
SLES feem ntau suav hais tias muaj kev nyab xeeb rau nws cov kev npaj siv thaum tsim ntawm qhov tsim nyog, tab sis tuav cov concentrated 70% paste yuav tsum tau ceev faj. Nws tuaj yeem ua rau lub qhov muag ntawm kev sib cuag ncaj qha, yog li cov tsom iav thiab cov hnab looj tes tiv thaiv tau pom zoo thaum sib xyaw. Cov khoom tiav lawm yuav tsum ua raws li cov kev txwv kev txwv rau kev yaug - tawm thiab tawm - ntawm cov tshuaj pleev ib ce los ntawm cov cai hauv cheeb tsam.
1,4-dioxane cov ntsiab lus ntawm SLES 70% yog ib qho tseem ceeb tsis zoo saib xyuas los ntawm lub luag hauj lwm cov neeg tsim khoom, thiab cov neeg yuav khoom yuav tsum tau thov daim ntawv pov thawj ntawm kev soj ntsuam kom paub meej tias tus nqi yog nyob rau hauv specification.
