Daim Ntawv Thov ntawm Fatty Amine Polyglycerol Ether Surfactants

Cov qauv ntawm cov rog amine polyglycerol ethercov tshuaj surfactantstau qhia hauv daim duab hauv qab no. Lawv cov pab pawg hydrophilic kuj tseem muaj cov pab pawg hydroxyl thiab ether bonds. Txawm li cas los xij, qhov kev hloov pauv ntawm cov pab pawg hydroxyl thiab ether bonds txawv ntawm polyoxyethylene ether nonionic surfactants, uas yog dominated los ntawm ether bonds. Tom qab yaj hauv dej, sib nrug los ntawm kev tsim cov hydrogen bonds tsis muaj zog ntawm cov pa oxygen ntawm ether bonds thiab hydrogen atoms hauv dej zoo li polyoxyethylene ether surfactants, lawv kuj tuaj yeem cuam tshuam nrog dej los ntawm hydroxyl pab pawg. Vim li no, fatty amine polyglycerol ether surfactants tuaj yeem ua tiav cov dej solubility zoo nrog cov lej me me ntawm glycidol adducts, thiab lawv cov hydrophilicity zoo dua li ntawm polyoxyethylene ether surfactants.

Ntxiv rau, cov roj amine polyglycerol ether surfactants muaj cov qauv ntawm cov organic amines, ua rau lawv muaj cov khoom ntawm ob qho tib si nonionic thiab cationic surfactants. Thaum tus lej ntawm cov adducts tsawg, lawv qhia cov yam ntxwv ntawm cationic surfactants, xws li acid tsis kam tab sis alkali tsis kam thiab qee yam kev ua haujlwm bactericidal. Thaum tus lej ntawm cov adducts nce, lawv cov khoom nonionic dhau los ua qhov tseem ceeb dua. Lawv yuav tsis precipitate hauv alkaline daws teeb meem thiab lawv cov haujlwm saum npoo tseem nyob ruaj khov. Nrog kev txhim kho nonionicity thiab cationicity tsis muaj zog, lawv qhov tsis sib xws nrog anionic surfactants raug txo qis, tso cai rau ob hom surfactants siv ua ke.

Siv rau hauvkev lag luam ntxuav

Cov roj amine polyglycerol ether surfactants ua rau muaj ntau yam khoom sib txawv nyob ntawm lawv cov lej adduct. Tus lej adduct qis muab rau lawv cov yam ntxwv ntawm cationic surfactants, txhim kho lawv cov solubility ntawm qhov kub qis thiab xa cov tshuaj ntxuav zoo heev dhau ntawm qhov kub thiab txias dav. Thaum tus lej adduct nce, lawv tus cwj pwm nonionic dhau los ua qhov tseem ceeb dua. Lawv yuav tsis precipitate hauv alkaline cov tshuaj thiab lawv cov haujlwm saum npoo tseem nyob ruaj khov. Nrog cov khoom nonionic txhim kho thiab cov khoom cationic tsis muaj zog, kev sib xyaw lawv nrog anionic surfactants tuaj yeem txo qhov nro ntawm qhov chaw thiab txhim kho emulsifying thiab wetting peev xwm. Zoo ib yam li hydrophilicity thiab steric hindrance nyhuv ntawm polyoxyethylene saw, cov surfactants no kuj tseem tuaj yeem tiv thaiv qhov nag lossis agglomeration ntawm cov tshuaj ntxuav. Tsis tas li ntawd, fatty amine polyglycerol ethers muaj cov khoom softening thiab antistatic, uas tuaj yeem daws qhov teeb meem ntawm kev xav tsis zoo ntawm cov khoom fiber tom qab ntxuav.

Siv raucov tshuaj tua kab emulsifiers

Ntxiv rau qhov ua tau zoo heev ntawm cov tshuaj surfactants uas tsis yog ionic, cov tshuaj fatty amine polyglycerol ether surfactants kuj muaj qee yam khoom tua kab mob thiab tua kab mob ntawm cov tshuaj cationic surfactants, ua rau lawv muaj ntau yam khoom sib xyaw ua ke. Lawv tuaj yeem ua rau turbidity nce thiab txhim kho solubility ntawm qhov kub qis, uas ua rau qhov kub hloov pauv ntawm cov tshuaj tua kab microemulsions uas tsim nrog lawv zoo heev. Hom tshuaj sib xyaw ua ke no, fatty amine polyglycerol ether, muaj txiaj ntsig zoo hauv kev tsim O / W microemulsions. Nws pab txo cov tshuaj surfactants thiab txo cov nqi tsim khoom.

Npaj tus neeg sawv cev antistatic

Cov roj amine polyglycerol ether surfactants tuaj yeem tsim cov dej txuas ntxiv mus rau ntawm qhov chaw fiber ntawm cov hydrogen bonds ntawm lawv cov hydrophilic pawg, hydroxyl pawg thiab cov dej molecules, yog li xa cov dej noo zoo heev thiab conductivity. Lub caij no, lawv tuaj yeem tsim cov roj hydrophobic zaj duab xis ntawm qhov chaw fiber kom txo cov fiber sib txhuam thiab hluav taws xob static, thiab tseem muab cov fibers nrog softness thiab smoothness. Tsis tas li ntawd, qhov hydrophobic ntu ntawm fatty amine polyglycerol ether surfactants zoo ib yam li cov fatty amine polyoxyethylene ether. Txij li thaum glycidol hloov ethylene oxide ntxiv rau nws qhov hydrophilic ntu, nws muaj zog hydrophilicity. Yog li ntawd, nws cov dej noo nqus thiab conductivity ua tau zoo dua li cov polyoxyethylene ether surfactants feem ntau. Ntxiv mus, fatty amine polyglycerol ether surfactants tsis muaj tshuaj lom thiab khaus ntau dua li cationic surfactants, ua rau lawv cog lus tias muaj kev ua haujlwm siab antistatic.

Npaj me mecov khoom siv tu tus kheej

Hauv kev npaj cov roj amine polyglycerol ether surfactants los ntawm glycidol, cov qauv ntawm cov roj amine polyglycerol ethers muaj cov ether bonds thiab hydroxyl pawg hloov chaw ntawm kev tswj hwm los ntawm ether bonds. Qhov no tiv thaiv kev tsim cov dioxane, ua rau cov surfactants no muaj kev nyab xeeb dua li polyoxyethylene ether-type surfactants. Tsis tas li ntawd, cov roj amine polyglycerol ether surfactants muaj ntau cov hydroxyl pawg, uas txhim kho hydrophilicity, txo qhov khaus thiab xa cov teebmeem me me rau tib neeg lub cev. Yog li ntawd, lawv tau siv los tsim cov khoom siv saib xyuas tus kheej me me, tshwj xeeb tshaj yog cov rau cov menyuam mos thiab cov menyuam yaus.

Daim ntawv thov hauv kev kho qhov chaw pigment

Cov kev tshawb fawb tau qhia tias cov tshuaj surfactants nonionic ntawm cov rog amine hom muab cov txiaj ntsig zoo heev hauv kev hloov pauv ntawm cov xim ntsuab phthalocyanine. Qhov kev ua tau zoo yog vim muaj cov laj thawj hauv qab no: cov surfactants no tuaj yeem adsorbed rau ntawm qhov chaw ntawm cov xim los ntawm kev tsim cov hydrogen bonds ntawm cov hydrogen atoms hauv hydroxyl pawg (-OH) thiab amino pawg (-NH3) thiab cov nitrogen atoms ntawm qhov chaw ntawm cov xim ntsuab phthalocyanine. Lawv cov lipophilic hydrocarbon saw ces tsim cov zaj duab xis adsorbed. Cov txheej no zoo tiv thaiv kev sib sau ua ke ntawm cov xim thaum lub sijhawm ziab thiab tiv thaiv kev loj hlob ntawm cov noob siv lead ua, thaum kawg ua rau cov xim nrog cov siv lead ua zoo.

Thaum cov xim hloov kho tau muab tso rau hauv cov organic media, cov saw hlau hydrocarbon, uas muaj kev sib raug zoo nrog cov organic media, sai sai dhau los ua cov kua nplaum los tsim cov zaj duab xis solvated. Qhov no ua rau cov xim tawg thiab tiv thaiv flocculation thaum cov khoom me me ze rau ib leeg. Cov nyhuv no tau txhim kho thaum cov saw hlau hydrocarbon ntev thiab cov zaj duab xis solvated tuab, uas pab txhim kho cov xim me me thiab ua tiav qhov kev faib tawm me me. Cov pab pawg hydrophilic ntawm cov surfactants tsim cov zaj duab xis hydrated tom qab hydration, uas kuj tseem cuam tshuam kev flocculation ntawm cov xim me me thiab txhim kho lawv cov dispersibility.

Cov roj amine polyglycerol ether surfactants muaj hydrophilicity siab dua thiab tuaj yeem tsim cov zaj duab xis hydrated tuab dua. Yog li ntawd, cov pigments kho nrog cov surfactants no tawg yooj yim dua hauv dej nrog cov khoom me me, qhia txog kev cia siab rau kev siv rau lawv hauv kev kho qhov chaw ntawm phthalocyanine ntsuab pigments.
