Cov qauv ntawm cov rog amine polyglycerol ether surfactants yog raws li nram no: Pawg hydrophilic kuj tseem muaj cov hydroxyl pawg thiab ether bonds, tab sis qhov tshwm sim ntawm cov hydroxyl pawg thiab ether bonds hloov pauv qhov xwm txheej ntawm polyoxyethylene ether nonionic surfactants, uas yog dominated los ntawm ether bonds. Tom qab yaj hauv dej, ntxiv rau kev tsim cov hydrogen bonds tsis muaj zog los ntawm cov pa oxygen atoms ntawm ether bonds nrog hydrogen atoms hauv dej zoo li qhov kawg, lawv kuj tuaj yeem cuam tshuam nrog dej los ntawm hydroxyl pawg. Yog li ntawd, fatty amine polyglycerol ether surfactants tuaj yeem ua tiav cov dej solubility zoo nrog cov lej me me ntawm glycidol ntxiv, yog li hydrophilicity ntawm fatty amine polyglycerol ether surfactants muaj zog dua li ntawm polyoxyethylene ether surfactants. Ntxiv rau, cov roj amine polyglycerol ether surfactants kuj muaj cov qauv ntawm cov organic amines, ua rau lawv muaj qee yam ntxwv ntawm ob qho tib si nonionic thiab cationic surfactants: thaum tus lej ntawm kev ntxiv me me, lawv qhia cov yam ntxwv ntawm cationic surfactants, xws li acid tsis kam tab sis tsis alkali tsis kam, thiab qee yam khoom bactericidal; thaum tus lej ntawm kev ntxiv loj, cov khoom nonionic nce, lawv tsis precipitate hauv alkaline daws, qhov kev ua haujlwm ntawm qhov chaw tsis raug rhuav tshem, cov khoom nonionic nce, thiab cov khoom cationic txo qis, yog li qhov tsis sib xws nrog anionic surfactants tsis muaj zog, thiab ob qho tuaj yeem sib xyaw rau kev siv.
1. Siv rau hauv kev lag luam ntxuav khaub ncaws
Cov tshuaj surfactants ntawm cov rog amine polyglycerol ether ua rau pom cov yam ntxwv sib txawv nrog cov lej ntxiv sib txawv: thaum tus lej ntxiv me me, lawv qhia cov yam ntxwv ntawm cationic surfactants, uas ua rau lawv cov solubility ntawm qhov kub qis thiab muab rau lawv cov tshuaj ntxuav zoo dua li qhov kub dav; thaum tus lej ntxiv loj, cov khoom tsis-ionic nce ntxiv, yog li lawv tsis precipitate hauv alkaline cov tshuaj thiab lawv cov haujlwm saum npoo tseem tsis puas. Vim yog cov khoom tsis-ionic nce ntxiv thiab cov khoom cationic txo qis, thaum sib xyaw nrog anionic surfactants, lawv tuaj yeem txo qhov nro ntawm qhov chaw thiab txhim kho emulsifying thiab wetting peev xwm; zoo ib yam li polyoxyethylene saw, lawv cov hydrophilicity thiab steric hindrance effect kuj muaj cov nyhuv inhibitory pom tseeb ntawm cov nag lossis agglomeration ntawm cov tshuaj ntxuav. Tsis tas li ntawd, fatty amine polyglycerol ether muaj qee yam khoom mos thiab antistatic, yog li thaum siv rau hauv cov ntaub ntxuav, nws tuaj yeem daws qhov tsis zoo ntawm tes tsis zoo tom qab ntxuav.
1. Siv ua cov tshuaj tua kab emulsifiers
Ntxiv rau qhov muaj cov nyhuv emulsifying zoo ntawm cov surfactants uas tsis yog ionic, cov rog amine polyglycerol ether surfactants kuj muaj qee yam kev ua haujlwm bactericidal thiab tua kab mob ntawm cov cationic surfactants, ua rau lawv ua "ntau yam nyhuv" sib xyaw surfactant: lawv tsis tsuas yog ua rau lawv cov turbidity nce ntxiv tab sis kuj txhim kho lawv cov solubility ntawm qhov kub qis, yog li txhim kho lawv qhov kev hloov pauv kub zoo li cov tshuaj tua kab microemulsions. Cov surfactant sib xyaw no, fatty amine polyglycerol ether, muaj kev ua haujlwm siab hauv kev tsim O / W microemulsions, uas tuaj yeem txo qhov koob tshuaj ntawm surfactants thiab txo cov nqi.
1. Kev npaj cov neeg sawv cev antistatic
Cov roj amine polyglycerol ether surfactant tuaj yeem tsim cov dej txuas ntxiv mus rau ntawm qhov chaw fiber los ntawm kev sib txuas hydrogen ntawm cov pab pawg hydrophilic, cov pab pawg hydroxyl thiab cov dej molecules, yog li muaj kev nqus dej zoo thiab cov teebmeem conductive. Nws kuj tseem tuaj yeem txo cov fiber sib txhuam thiab electrostatic tiam los ntawm kev tsim cov roj hydrophobic zaj duab xis ntawm qhov chaw fiber, thiab kuj tuaj yeem ua rau pom cov teebmeem mos thiab du. Tsis tas li ntawd, qhov hydrophobic ib feem ntawm fatty amine polyglycerol ether surfactant zoo ib yam li cov fatty amine polyoxyethylene ether, thiab qhov hydrophilic ib feem yog hydrophilic ntau dua li qhov qub vim tias nws tau ntxiv nrog glycidol es tsis txhob ethylene oxide, yog li nws cov dej nqus thiab cov teebmeem conductive muaj zog dua li cov ntawm cov polyoxyethylene ether surfactants dav dav. Ntxiv mus, qhov tshuaj lom thiab khaus ntawm fatty amine polyglycerol ether surfactant qis dua li cov ntawm cationic surfactants, yog li nws xav tias yuav dhau los ua tus neeg sawv cev zoo heev antistatic.
1. Kev npaj cov khoom siv tu cev tsis hnyav
Hauv cov txheej txheem ntawm kev npaj cov roj amine polyglycerol ether surfactants los ntawm glycidol, txij li cov qauv ntawm cov roj amine polyglycerol ether muaj cov ether bonds thiab hydroxyl pawg hloov pauv es tsis yog raug tswj hwm los ntawm ether bonds, kev tsim cov dioxane tuaj yeem zam tau. Nws qhov kev nyab xeeb siab dua li ntawm polyoxyethylene ether hom surfactants. Ntxiv mus, muaj ntau tus lej ntawm cov hydroxyl pawg hauv cov roj amine polyglycerol ether surfactants, uas ua rau hydrophilicity, txo qhov khaus, thiab ua rau lawv mos dua rau tib neeg lub cev. Yog li ntawd, cov roj amine polyglycerol ether surfactants yog siv los npaj cov khoom siv saib xyuas tus kheej mos, tshwj xeeb tshaj yog cov rau cov menyuam mos thiab cov menyuam yaus.
1. Daim ntawv thov hauv kev kho qhov chaw pigment
Cov kev tshawb fawb tau pom tias cov surfactants uas tsis yog ionic ntawm hom fatty amine tuaj yeem ua tiav cov txiaj ntsig zoo hauv kev kho cov xim ntsuab phthalocyanine. Qhov laj thawj rau qhov txiaj ntsig zoo no yog tias cov surfactants no tuaj yeem adsorbed rau ntawm qhov chaw ntawm cov xim ntsuab phthalocyanine los ntawm kev tsim cov hydrogen bonds ntawm -H hauv -OH thiab -NH thiab nitrogen ntawm qhov chaw ntawm cov xim ntsuab phthalocyanine. Lawv tsim cov zaj duab xis adsorbed nrog lawv cov saw hydrocarbon lipophilic, thiab cov zaj duab xis txheej tsim tuaj yeem tiv thaiv kev sib sau ua ke ntawm cov xim thaum lub sijhawm ziab, yog li ntawd txwv tsis pub kev loj hlob ntawm cov noob siv lead ua thiab tau txais cov xim nrog cov siv lead ua zoo. Hauv cov xov xwm organic, cov xim kho tau sai sai solvate los tsim cov zaj duab xis solvated vim muaj kev sib raug zoo ntawm cov saw hydrocarbon thiab cov xov xwm organic, ua rau cov xim yooj yim rau disperse. Tib lub sijhawm, nws kuj tseem tuaj yeem tiv thaiv flocculation thaum cov xim me me los ze rau ib leeg. Cov nyhuv no tau txhim kho thaum cov saw hydrocarbon ntev nce thiab cov zaj duab xis solvated thickens, uas yog qhov zoo rau kev txhim kho thiab kev faib tawm nqaim ntawm cov xim me me. Lawv cov pab pawg hydrophilic tsim cov zaj duab xis hydrated los ntawm kev hydration, uas tuaj yeem tiv thaiv flocculation ntawm cov xim me me thiab ua rau lawv yooj yim rau disperse. Fatty amine polyglycerol ether surfactants muaj hydrophilicity muaj zog dua thiab tuaj yeem tsim cov zaj duab xis hydrated tuab dua. Yog li ntawd, cov pigments kho nrog fatty amine polyglycerol ether surfactants yooj yim dispersed hauv dej, nrog cov khoom me me, qhia tias lawv muaj kev cia siab zoo hauv kev kho qhov chaw ntawm phthalocyanine ntsuab pigments.
