Cov txheej txheem kev txheeb xyuas nrov tam sim no ntawm toner yog raws li hauv qab no:
Co nws nyuaj ua ntej thiab saib cov npuas tom qab co.
1. Yog hais tias cov npuas yog mos thiab nplua nuj, nrog ib txheej tuab, thiab kav ntev, nws yog dej zoo;
2. Yog tias muaj npuas tsawg, nws txhais tau tias cov khoom noj muaj tsawg;
3. Yog tias cov npuas muaj ntau tab sis loj, nws txhais tau hais tias nws muaj salicylic acid, mmjj uas ua xua rau salicylic acid yuav tsum tsis txhob siv nws;
4. Yog tias muaj ntau npuas thiab tom qab ntawd ploj mus sai, nws txhais tau hais tias nws muaj cawv.
Qhov tseeb, txoj kev no yog qhov tsis txaus ntseeg, thiab nws tseem yog kev nkag siab yuam kev rau feem ntau ntawm cov neeg nyiam kev zoo nkauj.
Nws yog qhov tseeb tias qee cov khoom xyaw nquag hauv lub toner tuaj yeem ua npuas dej, tab sis lawv tag nrho cov ua npuas ncauj tsis muaj zog, thiab lub sijhawm tsis ntev,
Cov "ntse thiab nplua nuj" thiab "ntev-ntev" ua npuas ncauj hais saum toj no tsis yog cov txiaj ntsig ntawm cov khoom xyaw nquag tab sis yog tshwm sim los ntawm surfactants (feem ntau ntxiv rau lub ntsej muag ntxuav kom huv). Surfactants tsis muaj nqi kho tawv nqaij. Xws li surfactants yuav rhuav tshem cov zaj duab xis sebum, tab sis vim li cas peb ntxiv cov khoom xyaw no rau peb cov toner. Vim tias qee cov khoom xyaw nquag yog roj-soluble thiab tsis tuaj yeem yaj ncaj qha hauv dej, surfactants yuav tsum tau qhwv cov khoom xyaw kom lawv tuaj yeem nyob ruaj khov hauv dej. Yog li ntawd, qhov tsim nyog ntawm qhov kev ua si saum npoo yog tseem tsim nyog, tab sis yog tias koj ntxiv ntau dhau, nws tsis zoo, nws yuav ua rau lub nra tsis tsim nyog rau ntawm daim tawv nqaij, thiab tseem tuaj yeem ua rau khaus khaus.
Yuav ua li cas paub seb qhov kev ua haujlwm ntawm lub toner yog ntau dhau? Los ntawm cov lus piav qhia saum toj no, peb twb tau nkag siab tias cov khoom xyaw uas ua rau cov npuas dej nplua nuj tsis yog cov khoom xyaw uas muaj txiaj ntsig zoo ntawm daim tawv nqaij tab sis cov kev ua haujlwm ntawm lub ntsej muag. Yog li ntawd, nws tsis tuaj yeem txiav txim siab tus nqi ntawm cov khoom xyaw nquag los ntawm kev ua npuas dej.
Tab sis koj tuaj yeem paub seb qhov kev ua haujlwm saum npoo av puas dhau lawm. Tom qab co lub toner, cia nws sawv ntsug li 15 feeb. Yog tias tseem muaj txheej txheej tuab, ces koj tuaj yeem xav hloov lub raj mis ntawm toner. Yog tias ntau cov av tuaj yeem tshem tawm los ntawm cov dej ntawm cov paj rwb, nws kuj tuaj yeem txiav txim siab tias nws yog qhov dej los yog dej cawv ntau dhau. Kuv tus kheej tsis pom zoo nrog qhov no hu ua "secondary cleaning" kauj ruam. Kev ntxuav yuav tsum tsis yog ib qho teeb meem uas yuav tsum tau xav txog hauv lub toner. Txhawm rau kom muaj txiaj ntsig zoo "secondary cleansing", nws tsis tsim nyog rau lub tswm ciab ua rau cov tawv nqaij dais ntau cov khoom xyaw ntog.
Raws li rau salicylic acid, "salicylic acid yuav ua npuas ncauj, thiab npuas yuav loj thiab loj." Nyob deb, qhov tseeb, salicylic acid tsis muaj peev xwm ua npuas dej txhua.
Raws li rau cawv, cawv muaj ib tug defoaming nyhuv. Kev lag luam, defoaming cov khoom xyaw tau muab faib ua ob pawg - defoamers thiab foam suppressors:
Foam breaker: Tom qab ua npuas dej tau tsim, ntxiv qee qhov ua npuas ncauj, thiab cov npuas dej yuav ploj tam sim ntawd.
Foam inhibitor: Nws tau ntxiv thaum cov tshuaj tau npaj, kom nws nyuaj rau yaj thiab ua npuas ncauj.
Cawv yog ib yam ua npuas ncauj tawg. Yog li ntawd, tom qab co lub toner tawm ntawm ua npuas ncauj, ntxiv ib co cawv tuaj yeem defoam tiag tiag. Tab sis yog hais tias lub toner Ameslikas muaj cawv, tom qab ua npuas ncauj yog shaken, cawv yuav tsis muaj ntau defoaming nyhuv.
Muaj qhov kev sim no, ntxiv 2 feem pua emulsifier Tween 20 thiab 10 feem pua ntawm cawv hauv dej los ua cov tshuaj, co nws thiab cia nws sawv ntsug li 15 feeb, cov npuas dej tseem tuaj yeem tuav ib nrab ntawm qhov siab thaum nws nyuam qhuav shaken. Yog li ntawd, nws kuj yog ib qho kev to taub yuam kev los txiav txim seb cov cawv puas muaj raws li qhov ua npuas ncauj dissipates.
Tsis tas li ntawd, koj tsis tas yuav hnov qhov hloov xim ntawm cawv. Los ntawm qhov pom ntawm cov kuab tshuaj, cawv muaj kev nyab xeeb heev rau daim tawv nqaij. Qee cov khoom xyaw hauv cov khoom tu tawv nqaij yuav tsum tau yaj nrog kev pab ntawm cov kuab tshuaj cawv. Tsawg-concentration cawv kuj muaj kev nkag mus-txhawb cov nyhuv, uas tuaj yeem pab kom nkag mus ntawm cov khoom xyaw nquag. Qee cov toners, txhawm rau tsim kom muaj cov nyhuv txias thiab astringent, ntxiv cawv ntau, cov dej no tsuas yog tsim rau cov neeg uas muaj cov tawv nqaij tshwj xeeb.
