Qhov cuam tshuam ntawm surfactants ntawm daim tawv nqaij suav nrog ua cov tawv nqaij ua kom nruj, khaus tawv nqaij thiab tawv nqaij. Yog tias qhov txawv los ntawm cov hom kev ua si ua kom muaj zog (tom qab no hu ua cov khoom ua kom zoo nkauj), cov tshuaj ntxuav ntsej muag tuaj yeem muab faib ua cov tshuaj ntxuav tes thiab cov amino acid. Thiab cov tshuaj ntxuav tu lub ntsej muag.
(1) Xab npus ntxuav ntsej muag kom huv
Xab npum hauv paus yog tsim los ntawm kev nruab nrab ntawm cov rog ua kua thiab alkali. Fatty acid feem ntau muaj cov kua qaub lauric, myristic acid, palmitic acid thiab stearic acid. Cov alkali siv rau kev ua kom nruab nrab feem ntau yog potassium hydroxide.
Xab npum ntxuav lub ntsej muag muaj cov yam ntxwv ntawm kev ntxhib los mos, ua npuas nplua nuj, du thiab ntom, muaj peev xwm ntxuav tau yooj yim, yaug yooj yim, thiab rov qab los tom qab siv tas.
Vim tias cov roj ua kua ntsev yog alkaline, cov tshuaj ntxuav tes ntshiab si muaj pH ntawm 9-10, uas tsis sib haum nrog daim tawv nqaij' s pH ntawm 5, yog li nws tsis mob me rau daim tawv nqaij, thiab nws yog qhov yooj yim ua rau nruj thiab dryness tom qab ntxuav rau cov neeg uas muaj tawv tawv tawv.
(2) Amino acid ntxuav ntsej muag
Amino acid hom lub ntsej muag tshuaj ntxuav yog qhov nruab nrab kom tsis muaj zog tiv thaiv cov kua qaub rau lub ntsej muag tshuaj ntxuav uas muaj feem ntau ntawm cov amino acid system surfactants thiab lub hauv paus tsis tshua muaj kev ua kom huv.
Vim tias cov amino acid saum npoo kev ua haujlwm muaj kev ntxig nqig, zoo ua npuas dej ua haujlwm, zoo heev yaug kev ua haujlwm, zoo sib xws nrog daim tawv nqaij, tsis tshua tawv nqaij, qhov tsis zoo yog qhov tsis muaj zog ntawm lub zog foaming.
Muaj ntau ntau hom amino acid nto kev ua haujlwm. Cov amino acid type cleansing khoom mas suav nrog glycine hom, glutamic acid hom thiab methyl taurine hom.
(3) Foob ntsej muag tshuaj ntxuav kom huv
Sib txawv surfactants yuav muaj kev sib txawv thiab cov yam ntxwv. Txhawm rau txhim kho lub ntsej muag zoo dua, ua kom sib npaug ntawm cov npuas dej, ntxuav kev ua haujlwm, tawv ntawm lub ntsej muag thiab lub ntsej muag zoo nkauj thiab zoo nkauj yog feem ntau xaiv. Txoj kev ntawm surfactant compounding.
Piv txwv li: xab npum surfactants muaj ceev ua npuas ncauj, ntom thiab nplua nuj ua npuas ncauj, yooj yim los ntxuav, tab sis yuav nqa cov tawv nqaij qhuav tom qab ntxuav, AES system ua npuas ncauj kev ua haujlwm yog me ntsis tsis muaj zog, yuav muaj qhov kev xav zoo thaum lub sijhawm ntxuav, xab npum puag. thiab AES Cov lus sib xyaw ua kom yooj yim rau kev kho kom haum rau cov khoom nrog cov nplua nuj ua npuas thiab ua kom lub siab ua kom txias thiab muaj dej noo.
Lwm yam surfactant tebchaw tseem yuav muaj cov teebmeem synergistic zoo heev. Piv txwv li, kev siv cov amino acid surfactants nrog xab npum puag tuaj yeem txo qhov kev ua tsis haum ntawm xab npum puag; AES nrog amino acid surfactants tuaj yeem daws cov teeb meem ntawm cov tuab tuab ntawm amino acid surfactants; APG ua ke nrog cov ua ke amino acid rooj.
