Cov surfactants twg tuaj yeem siv los tswj ua npuas ncauj thaum ntxuav?

Tsawg-ua npuas ncauj surfactants suav nrog ntau qhov sib xyaw nonionic thiab amphoteric nrog kev ua haujlwm dav thiab muaj peev xwm siv tau. Nws yog ib qho tseem ceeb kom nco ntsoov tias cov surfactants tsis yog xoom-foaming agents. Hloov chaw, ntxiv rau lwm yam khoom, lawv muab ib txoj hauv kev los tswj tus nqi ntawm cov npuas dej hauv qee yam kev siv. Low-foam surfactants kuj txawv ntawm defoamers los yog antifoamers, uas yog additives tshwj xeeb tsim los txo los yog tshem tawm ua npuas ncauj. Surfactants muaj ntau lwm yam tseem ceeb hauv kev tsim, xws li ntxuav, ntub dej, emulsifying, dispersing, thiab lwm yam.

Amphoteric Surfactantscov

Amphoteric surfactants nrog cov npuas dej tsawg heev yog siv los ua dej-soluble surfactants hauv ntau hom kev tu. Cov khoom xyaw no muaj kev sib txuas, ruaj khov, tu, thiab ntub dej. Novel multifunctional amphoteric surfactants nthuav tawm cov yam ntxwv tsis tshua muaj foaming thaum muab kev ua haujlwm tu, zoo ib puag ncig thiab kev nyab xeeb profiles, thiab kev sib raug zoo nrog lwm cov nonionic, cationic, thiab anionic surfactants.

Nonionic Alkoxylatescov

Tsawg-ua npuas ncauj alkoxylates nrog ethylene oxide (EO) thiab propylene oxide (PO) cov ntsiab lus tuaj yeem xa cov dej yaug zoo tshaj plaws thiab tshuaj tsuag-ntxuav kev ua haujlwm rau ntau qhov kev kub ntxhov thiab kev siv tshuab tu. Piv txwv suav nrog cov khoom siv ntxuav tais diav tsis siv neeg, cov khoom siv mis thiab khoom noj khoom haus, cov ntaub ntawv ua cov ntaub ntawv thiab cov ntawv, cov tshuaj textile, thiab lwm yam. Tsis tas li ntawd, linear cawv-raws li alkoxylates muaj cov khoom ua npuas ncauj tsawg heev thiab tuaj yeem ua ke nrog lwm cov khoom ua npuas ncauj (piv txwv li, biodegradable dej-soluble polymers) los tsim cov tshuaj ntxuav kom zoo thiab txuag nyiaj.

EO/PO Block Copolymercov

EO / PO thaiv copolymers paub txog lawv cov khoom ntub dej zoo heev thiab cov khoom tawg. Cov ua npuas ncauj tsis tshua muaj nyob hauv pawg no tuaj yeem ua haujlwm tau zoo emulsifiers rau ntau yam kev lag luam thiab chaw ua haujlwm tu.

covTsawg-Foam Amine Oxides

Amine oxides nrog kev ntsuas ua npuas ncauj tsawg heev kuj tau lees paub rau lawv cov kev ua haujlwm tu hauv cov tshuaj detergents thiab degreasers. Thaum ua ke nrog cov npuas dej uas tsis tshua muaj amphoteric hydrogels, amine oxides tuaj yeem ua cov pob txha surfactant hauv ntau cov qauv rau cov tshuab ntxhua khaub ncaws uas tsis muaj npuas thiab cov ntaub ntawv siv hlau.

Linear Cawv Ethoxylatescov

Qee qhov linear cawv ethoxylates muaj qhov nruab nrab mus rau qis ua npuas ncauj thiab tuaj yeem siv rau hauv ntau yam tawv tawv daim ntaub ntawv. Cov surfactants no muaj cov tshuaj ntxuav tes zoo thiab ntub dej thaum tswj hwm ib puag ncig, kev noj qab haus huv, thiab kev nyab xeeb profiles. Tshwj xeeb, qis-HLB cawv ethoxylates qis qis mus rau nruab nrab foaming thiab tuaj yeem ua ke nrog high-HLB cawv methoxylates los tswj ua npuas ncauj thiab txhim kho cov roj solubility hauv ntau cov qauv kev lag luam tu.

Fatty Amine Ethoxylatescov

Qee cov fatty amine ethoxylates muaj cov khoom uas tsis tshua muaj foaming thiab tuaj yeem siv rau hauv kev ua liaj ua teb thiab kev ua kom huv si los yog cov khoom siv quav ciab los muab emulsifying, wetting, thiab dispersing zog.
