Thaum cov yam ntxwv tsis yog ionic nce ntxiv thiab cov yam ntxwv cationic poob qis, lawv qhov tsis sib haum nrog anionic surfactants yuav qaug zog, ua rau ob hom no siv tau ua ke.
Raukev ntxuav hauv kev lag luam
Cov tshuaj surfactants fatty amine polyglycerol ether muaj ntau yam khoom sib txawv nyob ntawm cov lej adduct sib txawv. Tus lej adduct qis ua rau cov surfactant muaj cov yam ntxwv ntawm cationic surfactants, txhim kho nws cov solubility ntawm qhov kub qis, thiab xa cov tshuaj ntxuav zoo heev ntawm ntau qhov kub thiab txias. Thaum tus lej adduct nce, tus cwj pwm nonionic nce, yog li cov surfactant yuav tsis precipitate hauv cov kua alkaline thiab nws cov dej num saum npoo tseem nyob ruaj khov. Raws li cov khoom nonionic muaj zog thiab cov khoom cationic tsis muaj zog, kev sib xyaw nws nrog anionic surfactants tuaj yeem txo qhov nro ntawm qhov chaw thiab txhim kho emulsifying thiab wetting kev ua tau zoo. Zoo ib yam li polyoxyethylene saw, nws cov hydrophilicity thiab steric hindrance effect tuaj yeem tiv thaiv cov nag lossis agglomeration ntawm cov tshuaj ntxuav. Ntxiv mus, fatty amine polyglycerol ether muaj qee yam khoom mos thiab antistatic, uas tuaj yeem kov yeej qhov teeb meem ntawm kev xav tsis zoo tom qab ntxuav cov khoom fiber.
Siv raucov tshuaj tua kab emulsifiers
Vim tias cov roj amine polyglycerol ether surfactants muaj cov khoom zoo heev ntawm cov nonionic surfactants thiab qee cov kab mob bactericidal thiab tua kab mob ntawm cationic surfactants, lawv ua haujlwm ua "multi-functional" sib xyaw surfactant. Lawv tsis tsuas yog tuaj yeem tsa turbidity tab sis kuj txhim kho solubility ntawm qhov kub qis, txhim kho qhov kub hloov pauv ntawm cov tshuaj tua kab microemulsions tsim nrog lawv. Cov surfactant sib xyaw no qhia tau tias muaj txiaj ntsig zoo hauv kev tsim O / W microemulsions, uas pab txo cov tshuaj surfactant thiab txiav cov nqi.
Kev npaj ntawmCov Neeg Sawv Cev Tiv Thaiv Hluav Taws Xob
Cov roj amine polyglycerol ether surfactants tuaj yeem tsim cov dej txuas ntxiv mus rau ntawm cov nplaim fiber ntawm cov hydrogen bonds ntawm cov hydrophilic pawg, hydroxyl pawg thiab cov dej molecules, yog li xa cov dej noo zoo thiab conductivity hluav taws xob. Lub caij no, lawv tuaj yeem tsim cov roj hydrophobic zaj duab xis ntawm cov nplaim fiber kom txo qis kev sib txhuam fiber thiab txo cov hluav taws xob static, thiab tseem muab cov mos mos thiab du. Tsis tas li ntawd, qhov hydrophobic ntu ntawm fatty amine polyglycerol ether surfactants zoo ib yam li cov fatty amine polyoxyethylene ethers. Txawm li cas los xij, glycidol hloov ethylene oxide yog ntxiv rau qhov hydrophilic ntu, ua rau muaj hydrophilicity muaj zog dua. Yog li ntawd, lawv cov dej noo nqus thiab kev ua tau zoo dua li cov polyoxyethylene ether surfactants ib txwm muaj. Ntxiv mus, fatty amine polyglycerol ether surfactants tsis muaj tshuaj lom thiab khaus ntau dua li cationic surfactants, ua rau lawv cog lus tias yuav yog cov neeg sawv cev antistatic ua tau zoo.
Kev npaj ntawmCov Khoom Siv Saib Xyuas Tus Kheej Me Me
Thaum lub sijhawm tsim cov roj amine polyglycerol ether surfactants siv glycidol, cov qauv molecular muaj cov ether bonds thiab hydroxyl pawg hloov pauv es tsis yog feem ntau ether bonds. Qhov no zam kev tsim dioxane thiab ua rau muaj kev nyab xeeb ntau dua piv rau polyoxyethylene ether surfactants. Ntxiv mus, cov hydroxyl pawg ntau hauv cov roj amine polyglycerol ether surfactants txhim kho hydrophilicity thiab txo qhov khaus, coj kev mos mos rau tib neeg daim tawv nqaij. Yog li ntawd, cov roj amine polyglycerol ether surfactants siv tau rau kev tsim cov khoom siv saib xyuas tus kheej, tshwj xeeb tshaj yog cov khoom siv saib xyuas tus kheej rau menyuam yaus.
Daim Ntawv Thov Hauv Kev Hloov Kho Qhov Chaw Pigment
Xu Yanli's kev tshawb fawb qhia tau hais tias cov roj amine-raws li nonionic surfactants ua tiav cov txiaj ntsig zoo hauv kev kho qhov chaw ntawm phthalocyanine ntsuab pigments. Qhov kev ua tau zoo xav tau los ntawm cov txheej txheem hauv qab no: cov surfactants no tuaj yeem adsorbed rau ntawm cov xim nto los ntawm hydrogen bonding tsim ntawm hydrogen atoms hauv -OH thiab -NH pawg thiab nitrogen atoms ntawm phthalocyanine ntsuab pigment nto. Lawv cov saw hydrocarbon lipophilic tsim ib zaj duab xis adsorbed. Lub txheej tsim tau zoo tiv thaiv kev sib sau ua ke ntawm cov xim pigment thaum lub sijhawm ziab thiab inhibits ntxiv crystal loj hlob, ua rau cov xim pigment crystalline zoo. Thaum cov pigments kho tau muab tso rau hauv cov organic media, cov saw hydrocarbon muaj kev sib raug zoo nrog cov organic media thiab sai sai solvate los tsim ib zaj duab xis solvation, pab txhawb kev sib cais xim. Lub caij no, zaj duab xis hinders flocculation thaum cov xim pigment pigment mus ze rau ib leeg. Cov nyhuv no intensifies nrog cov saw hydrocarbon ntev dua thiab cov zaj duab xis solvation tuab dua, nyiam cov xim pigment refinement thiab nqaim particle loj faib. Cov hydrophilic pawg hydrate los tsim cov zaj duab xis hydration, uas zoo suppress flocculation ntawm cov xim pigment pigments thiab pab txhawb kev sib cais. Cov roj amine polyglycerol ether surfactants muaj hydrophilicity zoo dua thiab tuaj yeem tsim cov zaj duab xis hydration tuab dua. Yog li ntawd, cov pigments kho nrog fatty amine polyglycerol ether surfactants disperse yooj yim dua hauv dej nrog cov khoom me me, qhia txog kev cia siab rau kev siv rau kev kho qhov chaw ntawm phthalocyanine ntsuab pigments.
