Thaum cov txheej txheem tsim khoom lag luam, ntau hom fouling, xws li coking, roj residues, nplai, sediments, thiab corrosive deposits, accumulates nyob rau hauv cov khoom thiab pipelines ntawm ntau lawm systems. Cov kev tso nyiaj no feem ntau ua rau cov khoom siv thiab cov kav dej tsis ua haujlwm, txo kev ua haujlwm ntawm cov tshuab tsim khoom, nce kev siv hluav taws xob, thiab hauv qhov xwm txheej hnyav, txawm tias muaj kev nyab xeeb.
Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm cov khoom siv hluav taws xob tshiab, tshiab kev lag luam fouling tau tshwm sim tsis tu ncua, thiab nws cov qauv molecular tau nce zuj zus. Tsis tas li ntawd, cov txheej txheem adhesion thiab cov ntaub ntawv ntawm kev lag luam fouling thiab ntau lub hom phiaj tu feem ntau nyob ntawm seb hom fouling nrog rau cov qauv tsim thiab qhov chaw physicochemical thaj chaw ntawm cov khoom raug ntxuav. Vim muaj kev tiv thaiv ib puag ncig, muaj kev xav tau ntau ntxiv rau biodegradability thiab non-toxicity ntawm cov tshuaj chemical, uas txuas ntxiv teeb meem tshiab rau kev siv tshuaj ntxuav cov thev naus laus zis.
Kev tu tshuaj lom neeg yog cov cuab yeej siv dav dav uas suav nrog kev kawm txog kev tsim fouling thiab cov khoom, kev xaiv thiab tsim cov tshuaj ntxuav thiab tshuaj ntxiv, kev xaiv cov tshuaj tiv thaiv corrosion, txheej txheem kev tu, kev txhim kho thiab siv cov cuab yeej ntxuav, tshuaj xyuas cov thev naus laus zis thaum ntxuav, thiab kev kho dej khib nyiab, thiab lwm yam. Ntawm cov no, kev xaiv cov neeg ua haujlwm tu yog qhov tseem ceeb hauv kev txiav txim siab kev ua tiav ntawm kev ua haujlwm tu, vim tias nws cuam tshuam ncaj qha rau kev ua haujlwm tu, descaling tus nqi, tus nqi corrosion, thiab nyiaj txiag cov txiaj ntsig ntawm cov khoom siv.
Cov tshuaj ntxuav tsev feem ntau muaj peb yam tseem ceeb: tus thawj tu tus neeg saib xyuas, corrosion inhibitors, thiab surfactants. Vim lawv cov qauv molecular, uas muaj ob pawg hydrophilic thiab hydrophobic, surfactants ua lub luag haujlwm hauv adsorption, nkag mus, emulsification, dissolution, thiab ntxuav thaum ntxuav tshuaj. Lawv tsis tsuas yog siv los ua tus neeg sawv cev pabcuam nkaus xwb tab sis kuj tseem suav tias yog cov khoom tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem xws li kua qaub tu, alkaline tu, corrosion inhibition, degreasing, thiab sterilization, qhov uas lawv muaj ntau zuj zus qhia lawv cov kev cuam tshuam loj.
Tus thawj tu tus neeg saib xyuas, corrosion inhibitors, thiab surfactants yog peb yam tseem ceeb ntawm cov tshuaj ntxuav kev daws teeb meem. Cov qauv tshuaj tshwj xeeb ntawm surfactants ua kom ntseeg tau tias, thaum yaj hauv cov kua dej, lawv txo qhov nro ntawm cov tshuaj, yog li txhim kho nws cov peev xwm ntub dej. Tshwj xeeb tshaj yog thaum cov concentration ntawm surfactants nyob rau hauv cov kev daws mus txog qhov tseem ceeb micelle concentration (CMC), cov kev hloov tseem ceeb tshwm sim nyob rau hauv cov kev daws teeb meem qhov nro, osmotic siab, viscosity, thiab optical zog.
Kev ntub dej, nkag mus, dispersing, emulsifying, thiab solubilizing los ntawm surfactants hauv tshuaj ntxuav cov txheej txheem ua tiav ob zaug qhov tshwm sim nrog ib nrab ntawm kev siv zog. Hauv cov ntsiab lus, surfactants hauv tshuaj ntxuav feem ntau ua haujlwm ob txoj haujlwm: ua ntej, lawv txhim kho qhov pom tseeb ntawm cov kuab tshuaj tsis zoo hauv cov kuab tshuaj los ntawm kev ua haujlwm solubilizing ntawm micelles, hu ua cov nyhuv solubilization; Thib ob, vim lawv cov pab pawg amphiphilic, surfactants adsorb lossis sib sau ua ke ntawm qhov sib cuam tshuam ntawm cov roj thiab dej theem, txo qis kev sib tshuam.
Thaum xaiv surfactants, tshwj xeeb yuav tsum tau them rau cov khoom ntawm cov tshuaj ntxuav, corrosion inhibitors, thiab surfactants, nrog rau kev sib raug zoo ntawm lawv cov kev sib cuam tshuam.
