Yog li ntawd yog vim li cas nws yog qhov ntau oily koj cov plaub hau, qhov tsawg frothy nws yog?(Thaum siv tib cov tshuaj zawv plaub hau).
Qhov tseeb, qhov no yog universal phenomenon.Thaum koj ntxuav koj cov plaub hau nrog cov plaub hau greaser, ua npuas ncauj yog txo sai.Qhov no puas txhais tau tias ua npuas ncauj ua haujlwm tsis zoo?Hauv lwm lo lus, yog qhov ua tau zoo ntawm kev ua npuas dej, qhov zoo dua lub peev xwm degreasing?
Peb twb paub los ntawm cov ntaub ntawv tau txais los ntawm kev sim ua npuas ncauj kom muaj nuj nqis thiab ua npuas ncauj durability yog txiav txim los ntawm cov khoom ua npuas ncauj ntawm surfactant nws tus kheej, uas yog, foaming zog thiab ua npuas ncauj stabilization zog.Lub peev xwm decontamination ntawm surfactant nws tus kheej yuav tsis muaj zog los ntawm kev txo cov npuas dej.Cov ntsiab lus no kuj tau ua pov thawj thaum peb tau ua tiav qhov kev txiav txim siab ntawm lub peev xwm degreasing ntawm tus activator deg, lub ntsej muag activator nrog cov khoom ua npuas ncauj zoo yuav tsis muaj lub zog zoo degreasing, thiab rov ua dua.
Tsis tas li ntawd, peb kuj tuaj yeem ua pov thawj tias tsis muaj kev sib raug zoo ntawm cov npuas dej thiab surfactant degreasing los ntawm cov qauv kev ua haujlwm sib txawv ntawm ob.
Kev ua haujlwm ntawm surfactant ua npuas ncauj:
Ua npuas ncauj yog ib daim ntawv ntawm tus neeg sawv cev ntawm qhov chaw nyob rau hauv cov xwm txheej tshwj xeeb, nws lub luag haujlwm tseem ceeb yog muab cov txheej txheem ntxuav kom xis nyob thiab zoo siab, ua raws li kev ntxuav cov roj ua lub luag haujlwm pabcuam, kom cov roj tsis yooj yim rau kev daws teeb meem hauv qab. qhov kev txiav txim ntawm cov npuas dej, yooj yim dua ntxuav tawm.
Lub hauv paus ntsiab lus ntawm foaming thiab degreasing ntawm surfactant:
Tus surfactant lub zog ntxuav los ntawm nws lub peev xwm los txo cov roj-dej interfacial nro (degreasing), es tsis yog nws lub peev xwm los txo cov dej-cua interfacial nro (foaming).
Raws li peb tau hais thaum pib ntawm tsab xov xwm no, surfactants yog amphiphilic molecules, ib qho yog hydrophilic thiab lwm yam yog hydrophilic.Yog li ntawd, nyob rau hauv tsawg concentrations, tus surfactant nyiam nyob twj ywm nyob rau saum npoo ntawm dej, nrog lipophilic (dej-ntxhais) kawg tig mus rau sab nraud, thawj npog cov nplaim dej, uas yog, cov dej-cua interface, thiab yog li txo. qhov nro ntawm no interface.
Txawm li cas los xij, thaum lub concentration ntau dhau ntawm qhov taw tes, cov surfactant yuav pib ua pawg, tsim cov micelles, thiab qhov nro ntawm lub ntsej muag yuav tsis poob lawm.Qhov concentration no yog hu ua qhov tseem ceeb micelle concentration.
Lub peev xwm foaming ntawm surfactants yog qhov zoo, qhia tau hais tias nws muaj peev xwm txo tau qhov kev sib tshuam ntawm cov dej thiab huab cua, thiab qhov tshwm sim ntawm qhov txo qis ntawm kev sib tshuam yog tias cov kua ua rau ntau qhov chaw (tag nrho thaj chaw ntawm ib pawg. ntawm npuas yog ntau dua li cov dej txias).
Lub zog decontamination ntawm cov surfactant yog nyob rau hauv nws lub peev xwm los ntub qhov chaw ntawm cov stain thiab emulsify nws, uas yog, "coat" cov roj thiab tso cai rau nws mus rau emulsified thiab ntxuav tawm nyob rau hauv dej.
Yog li ntawd, lub peev xwm decontamination ntawm surfactant txuas nrog nws lub peev xwm los qhib cov roj-dej interface, thaum lub peev xwm foaming tsuas yog sawv cev rau nws lub peev xwm los qhib cov dej-cua interface, thiab ob qho tib si tsis cuam tshuam tag nrho.Tsis tas li ntawd, kuj tseem muaj ntau yam uas tsis yog-foaming cleaners, xws li cov pleev Remover thiab pleev Remover roj uas feem ntau siv nyob rau hauv peb lub neej txhua hnub, uas kuj muaj ib tug muaj zog decontamination muaj peev xwm, tab sis tsis muaj npuas yog tsim, thiab nws yog pom tseeb hais tias ua npuas ncauj thiab decontamination. tsis yog tib yam.
Los ntawm kev txiav txim siab thiab kev tshuaj xyuas ntawm cov khoom ua npuas ncauj ntawm cov khoom sib txawv ntawm cov surfactant, peb tuaj yeem tau txais cov surfactant nrog cov khoom ua npuas ncauj zoo tshaj plaws, thiab tom qab ntawd los ntawm kev txiav txim siab thiab kev sib txuas ntawm lub zog degreasing ntawm surfactant, peb yuav tsum tshem tawm cov pa phem ntawm surfactant.Tom qab qhov kev sib koom ua ke no, muab kev ua si tag nrho rau qhov zoo ntawm cov surfactants sib txawv, ua kom cov surfactants ua tiav ntau dua thiab ua tau zoo dua, thiab tau txais kev tu zoo dua thiab siv kev paub.Tsis tas li ntawd, peb kuj paub los ntawm txoj cai ua hauj lwm ntawm surfactant tias ua npuas ncauj tsis cuam tshuam ncaj qha rau kev tu lub zog, thiab cov kev paub no tuaj yeem pab peb kom peb muaj kev txiav txim siab thiab kev paub thaum siv tshuaj zawv plaub hau, thiaj li xaiv cov khoom tsim nyog rau peb.
