Cov tshuaj surfactants uas tsis yog ionic yog ib pawg ntawm cov surfactants uas tsis ionize hauv cov kua dej, vim lawv cov qauv molecular tsis muaj cov pab pawg them. Piv rau cov tshuaj surfactants anionic, cov tshuaj surfactants nonionic muaj peev xwm ua kom emulsifying, ntub, thiab ntxuav tau zoo dua, nrog rau kev ua kom dej tawv zoo heev thiab sib xws nrog lwm cov tshuaj ionic surfactants. Cov yam ntxwv no ua rau lawv tseem ceeb heev rau ntau yam tshuaj ntxuav thiab cov qauv emulsifier.
Hauv cov teb ntawm cov tshuaj lom neeg txhua hnub thiab kev ntxuav hauv kev lag luam, cov tshuaj surfactants nonionic ua ntau lub luag haujlwm. Tsis tas li ntawd xwb, lawv kuj siv dav hauv cov khoom xws li cov khaub ncaws ntxhua khaub ncaws, cov tshuaj ntxuav kua, cov tshuaj ntxuav qhov chaw tawv, cov tshuaj ntxuav tais diav, thiab cov tshuaj ntxuav ntaub pua plag. Lawv cov txiaj ntsig zoo tshaj plaws hauv kev tshem tawm cov xim av thiab qhov mos mos ua rau lawv zoo tagnrho rau cov kev siv ntxuav no.
Cov kev lag luam zas xim ntaub thiab tawv yog cov chaw siv tseem ceeb rau cov tshuaj surfactants uas tsis yog ionic. Lawv siv rau hauv cov txheej txheem xws li carbonization ntawm cov plaub yaj, ntxuav, ntub, thiab rov ntub ntawm ntau yam fibers, nrog rau paj rwb desizing. Tsis tas li ntawd, lawv ua haujlwm ua cov neeg sawv cev leveling, cov neeg sawv cev degreasing, cov roj stabilizers, silicone roj emulsifiers, thiab cov neeg sawv cev tiav textile, ua lub luag haujlwm tseem ceeb hauv kev ua cov ntaub.
Kev lag luam ua hlau kuj siv cov tshuaj surfactants uas tsis yog ionic ntau heev. Lawv siv rau hauv cov txheej txheem xws li alkaline soaking, acid pickling, spray treatments, solvent degreasing, emulsion degreasing, thiab quenching, pab txhim kho qhov zoo thiab kev ua haujlwm ntawm cov hlau.
Hauv kev lag luam ua ntawv thiab pulp, cov surfactants nonionic feem ntau yog siv ua cov neeg sawv cev deinking, cov neeg sawv cev tswj cov resin, thiab cov neeg sawv cev sizing, ua kom zoo dua cov ntawv zoo thiab kev ua haujlwm ntau lawm.
Kev lag luam agrochemical siv cov surfactants nonionic ua cov dispersants, emulsifiers, thiab cov neeg sawv cev ntub kom txhim kho kev ua tau zoo ntawm cov tshuaj tua kab thiab lwm yam khoom agrochemical. Hauv kev lag luam yas thiab txheej, lawv ua haujlwm ua cov khoom pab hauv emulsion polymerization, emulsion stabilizers, thiab pigment wetting thiab dispersing agents.
Kev tsim cov roj av yog lwm qhov chaw tseem ceeb rau cov surfactants nonionic. Lawv yog siv ua cov khoom siv ntxiv xws li shale inhibitors, acidizing corrosion inhibitors, desulfurizing agents, drag reducers, corrosion inhibitors, dispersants, wax preventatives, thiab demulsifiers, ua lub luag haujlwm tseem ceeb hauv kev rho tawm roj av thiab kev ua cov roj av.
Ntxiv mus, cov surfactants nonionic yog siv ua cov binders thiab impregnating agents hauv asphalt electrode ntau lawm; ua emulsifiers, antioxidants, anticoagulants, binders, thiab lubricants hauv kev tsim tshuaj; ua ke nrog cov foaming thiab cov neeg sawv cev sau hauv kev tsim thee los txhim kho kev ua haujlwm flotation; thiab hauv kev tsim cov xim phthalocyanine los txhim kho qhov loj me ntawm cov khoom me me thiab tswj kev tawg.
Qhov ua tau ntau yam ntawm cov tshuaj surfactants nonionic thoob plaws ntau yam kev siv yog los ntawm lawv lub peev xwm los hloov cov yam ntxwv ntawm cov roj-kua, kua-kua, thiab kua-khoom sib txuas, muab rau lawv nrog cov haujlwm xws li ua npuas ncauj, tshem tawm npuas ncauj, emulsification, dispersion, nkag mus, thiab solubilization. Los ntawm kev tsim cov tshuaj pleev ib ce mus rau kev ua zaub mov, los ntawm cov khoom tawv mus rau cov xov hluavtaws, los ntawm kev zas xim rau cov ntaub ntawv tshuaj, thiab los ntawm kev ua kom cov ntxhia dej mus rau kev rho tawm roj av, lawv suav nrog yuav luag txhua yam ntawm kev ua haujlwm hauv kev lag luam tib neeg - khwv tau lawv lub npe ntawm "cov khoom siv txhim kho tsw qab zoo tshaj plaws hauv kev lag luam."
