Cov tshuaj surfactants yog ib pawg ntawm cov organic compounds nrog cov qauv tshwj xeeb, nrog keeb kwm ntev thiab ntau hom. Cov qauv molecular ib txwm muaj ntawm surfactants muaj ob qho tib si hydrophilic thiab hydrophobic qhov chaw, yog li muaj peev xwm txo qhov dej ntawm qhov chaw - uas kuj yog keeb kwm ntawm lawv cov npe. Surfactants koom nrog kev lag luam tshuaj zoo, uas muaj qib siab ntawm kev siv tshuab, ntau hom khoom, muaj nqis ntxiv, kev siv dav, thiab muaj zog cuam tshuam rau kev lag luam. Lawv ncaj qha pab ntau yam kev lag luam hauv kev lag luam hauv lub tebchaws thiab ntau yam kev lag luam high-tech. Kev txhim kho ntawm Tuam Tshoj txoj kev lag luam surfactant zoo ib yam li kev txhim kho tag nrho ntawm Tuam Tshoj txoj kev lag luam tshuaj zoo, ob qho tib si pib lig tab sis tsim kho sai.
Tam sim no, kev siv cov surfactants hauv kev lag luam yog dav heev, suav nrog ntau yam kev lag luam hauv tebchaws, xws li kev kho dej, fiberglass, coatings, kev tsim kho, xim, tshuaj lom neeg txhua hnub, kua mem, khoom siv hluav taws xob, tshuaj tua kab, textiles, luam ntawv thiab dyeing, tshuaj fibers, tawv, roj av, kev lag luam tsheb, thiab lwm yam, thiab tab tom nthuav dav mus rau ntau yam kev lag luam high-tech, muab kev txhawb nqa zoo rau kev lag luam high-tech xws li cov ntaub ntawv tshiab, biology, zog, thiab cov ntaub ntawv. Cov surfactants hauv tsev tau tsim kom muaj qee qhov kev lag luam, thiab lub peev xwm tsim cov surfactants loj tau zoo dua, uas tuaj yeem ua tau raws li cov kev xav tau hauv tsev thiab xa tawm qee yam khoom mus rau kev lag luam thoob ntiaj teb. Hauv kev siv tshuab, cov txheej txheem thev naus laus zis thiab cov khoom siv yooj yim yog qhov paub tab, thiab qhov zoo thiab kev muab khoom ntawm cov khoom siv raw tseem ceeb yog qhov ruaj khov, muab qhov kev lees paub yooj yim tshaj plaws rau kev txhim kho ntau yam ntawm kev lag luam surfactant.
Lub chaw yuav tsom mus rau kev tshaj tawm daim ntawv tshaj tawm txhua xyoo rau cov khoom surfactant (2024 version), uas suav nrog xya hom surfactants: cov surfactants uas tsis yog ionic surfactants, cov surfactants ionic surfactants, cov bio based surfactants, cov surfactants uas yog roj, cov surfactants tshwj xeeb, cov surfactants uas siv hauv kev lag luam tshuaj txhua hnub, thiab cov surfactants uas siv hauv kev lag luam textile.
