Daim ntawv thov ntawm ib pab pawg neeg surfactant

Kev sib tham ntawm daim ntawv thov ntawm ib pab pawg neeg surfactant uas yog qhov tshiab-tsis yog ntau npaum li cov khoom sib xyaw, tab sis hauv nws cov khoom siv ntau dua thiab cov ntawv thov-yuav tsum suav nrog kev lag luam xws li nws txoj haujlwm yuav ua tau nyob rau hauv kev ua lag luam surfactant. Surfactants tsim muaj ntau tus neeg ua haujlwm saum npoo av, tab sis ib pab pawg ntawm tsuas yog 10 hom sib txawv tsim cov lag luam surfactant. Daim ntawv thov tseem ceeb ntawm kev sib txuas tuaj yeem xav tau tsuas yog thaum nws koom nrog pawg no. Yog li, ntxiv rau qhov ua tau zoo thiab muaj kev nyab xeeb rau ib puag ncig, cov khoom lag luam yuav tsum muaj nyob rau ntawm tus nqi tsim nyog, piv rau lossis txawm tias muaj txiaj ntsig zoo dua li cov surfactants twb tau tsim hauv khw.

Ua ntej xyoo 1995, qhov tseem ceeb tshaj plaws surfactant tseem yog cov xab npum zoo tib yam, siv rau ntau txhiab xyoo. nws yog ua raws los ntawm alkylbenzene sulfonate thiab polyoxyethylene alkyl ethers, ob qho tib si muaj zog sawv cev rau txhua hom detergents, uas yog lub ntsiab qhov hluav taws xob rau surfactants. Thaum alkylbenzene sulfonate yog suav tias yog "tus neeg ua haujlwm" ntawm cov ntxhua khaub ncaws, cov roj cawv sulfate thiab ether sulfate yog cov tseem ceeb tshaj plaws rau cov khoom tu tus kheej. Los ntawm kev siv cov kev tshawb fawb tau pom tias alkyl polyglucosides, ntawm lwm tus, tuaj yeem them lub luag haujlwm hauv ob qho tib si. lawv tuaj yeem ua ke nrog lwm cov nonionic surfactants kom muaj txiaj ntsig zoo rau cov ntxhua khaub ncaws hnyav thiab nrog sulfate surfactants hauv cov tshuaj ntxuav tes, nrog rau hauv daim ntawv thov kev tu tus kheej. Yog li, surfactants uas tuaj yeem hloov tau los ntawm alkyl polyglucosides muaj xws li linear alkylbenzene sulfonate thiab sulfate surfactants, ntxiv rau cov nqi siab dua xws li betaines thiab amine oxides.

Kev kwv yees ntawm kev hloov pauv peev xwm ntawm alkyl polyglucosides yuav tsum tau them nyiaj rau cov nqi tsim khoom, uas dhau los ua ntau dua ntawm sulfate surfactants. Yog li, alkyl polyglucosides yuav siv rau ntawm qhov loj me tsis yog vim "ntsuab nthwv dej" thiab kev txhawj xeeb ntawm ib puag ncig, tab sis kuj yog vim cov nqi tsim khoom thiab raws li xav tau los ntawm ntau lub zog physicochemical, lawv cov kev ua tau zoo hauv ntau daim ntawv thov.

Alkyl polyglucosides yuav txaus siab rau qhov twg qhov kub tsis siab dhau thiab qhov nruab nrab tsis yog acidic heev vim tias cov acetals ntawm cov qauv qab zib uas hydrolyze rau fatty cawv thiab qabzib. Kev ruaj ntseg mus ntev yog muab ntawm 40 ℃ thiab PH ≥4. Ntawm qhov nruab nrab PH nyob rau hauv cov tshuaj tsuag kom qhuav, kub txog li 140 ℃ tsis txhob rhuav tshem cov khoom.

Alkyl polyglucosides yuav txaus siab rau kev siv txhua qhov chaw uas lawv qhov kev ua tau zoo tshaj plaws surfactant thiab cov khoom muaj txiaj ntsig ecotoxicological xav tau, piv txwv li, hauv cov tshuaj pleev ib ce thiab cov khoom siv hauv tsev. tab sis lawv cov kev sib tshuam ntawm lub ntsej muag tsawg heev, muaj zog dispersing siab, thiab tswj tau yooj yim foaming ua rau lawv txaus nyiam rau ntau yam kev siv. Lub peev xwm los thov cov tshuaj surfactant tsis yog nyob ntawm nws tus kheej cov khoom xwb tab sis tseem ntau dua ntawm nws qhov kev ua tau zoo thaum ua ke nrog lwm cov surfactants. Ua me ntsis anionic, los yog betaine surfactants. Ua nyiaj pub rau huab phenomena. Lawv kuj sib xws nrog cationic surfactants.

Muaj ntau zausalkyl polyglucosidesnthuav tawm cov txiaj ntsig zoo sib xyaw ua ke nrog lwm cov surfactants, thiab cov tswv yim siv ntawm cov teebmeem no tau tshwm sim hauv daim duab ntawm ntau tshaj 500 daim ntawv thov patent txij li xyoo 1981. cov npog tais diav no; lub luag haujlwm hnyav thiab lub luag haujlwm hnyav; txhua lub hom phiaj ntxuav; alkaline ntxuav; cov khoom tu tus kheej xws li tshuaj zawv plaub hau, da dej gels, tshuaj pleev, thiab emulsions; technical dispersions xws li xim pastes; formulations ua npuas ncauj inhibitors; demulsifiers; Cov tshuaj tiv thaiv cov nroj tsuag; lubricants; hydraulic kua; thiab roj ntau lawm tshuaj, rau npe ob peb.
