Mukayika zovala mu chowumitsira kuti ziume, onjezerani zofewetsa zovala ndi zofewa za zovala zomwezo, koma chofewetsa chovala mu chofewetsa chimatulutsidwa mumlengalenga.Chochepetsera chochepa kwambiri cha zovala zofewa ndi zinthu zotsutsana ndi ma static zomwe zimawonjezeredwa panthawi yowumitsa zimafalikira mumlengalenga wofunda ndikulowa mu ulusi wazinthu zonyowa, motero zimagwira ntchito.
Nsalu zofewetsa ndi zopangira zinthu, mankhwala omwe amachita kuti achepetse kupsinjika kwapakati pakati pa zinthu ziwiri zosiyana.Sopo ndi zotsukira nazonso ndi zopangira zomwe zimathandizira kuchepetsa kupsinjika kwamafuta, zomwe zimapangitsa kuti dothi lamafuta likhale losavuta kutsuka.
Mamolekyu a surfactant amakhala ndi zigawo ziwiri: chigawo chimodzi chimasungunuka mumafuta koma osasungunuka m'madzi, pomwe chinacho ndi chosiyana.Gawo lamafuta omwe amapezeka muzofewetsa nsalu nthawi zambiri amakhala okwera, ndipo nthawi zambiri pamakhala unyolo wautali wamafuta okhala ndi magulu osungunuka m'madzi, ena mwa iwo ndi anionic.mlandu woipa) kapena cationic (malipiro abwino), ndipo ena samalipidwa (magetsi osalowerera ndale).
Zigawo zamafuta za chofewa cha nsalu zimapanga filimu yowonda kwambiri yamafuta pamwamba pa ulusi womwe umalumikizana wina ndi mnzake, kuti muchepetse kugundana kwa ulusi womwe umathamangira wina ndi mzake, kuti malo oyenda azitha kuyenda mosavuta. iwo.Magulu a cationic kapena osakhala a ionic osungunuka m'madzi amagwiritsidwa ntchito kuthetsa magetsi osasunthika omwe amapangidwa ndi anions ambiri omwe amaphatikizidwa ndi zovala.
Zofewa zamtundu wa cationic ndi tallow-based dimethyl ammonium chloride, etc., pomwe zofewa za nonionic ndi polyethylene glycol stearate, etc.
