Kana mhepo ikapinda mumvura, sezvo isinganyungudike mumvura, inokamurwa kuita mabubbles akawanda nemvura pasi pesimba rekunze, zvichiita system yakasiyana. Kana mhepo yapinda mumvura yoita furo, nzvimbo yekubatana pakati pegasi nemvura inowedzera, uye simba remahara resystem rinokwirawo zvinoenderana.
Nzvimbo yakaderera inoenderana neyatinowanzo dana kuti critical micelle concentration (CMC). Saka, kana surfactant concentration yasvika paCMC, pane huwandu hwakakwana hwema surfactant molecules musystem kuti agare akabatana pamusoro pemvura, zvichiita kuti pave negap-free monomolecular film layer. Izvi zvinoderedza kushushikana kwenzvimbo yesystem. Kana kushushikana kwenzvimbo kukadzikira, simba remahara rinodiwa pakugadzira furo musystem rinodzikirawo, zvichiita kuti kuumbwa kwefuro kuve nyore.
Mukugadzirwa uye kushandiswa kwezvinoshanda, kuti ive nechokwadi chekuti emulsions dzakagadzirwa dzakagadzikana panguva yekuchengetwa, huwandu hwesurfactant hunowanzo gadziriswa pamusoro pehuwandu hwe micelle hunokosha. Kunyange zvazvo izvi zvichiwedzera kugadzikana kwe emulsion, zvine zvimwe zvinokanganisa. Ma surfactants akawandisa haangoderedzi chete kushushikana kwenzvimbo asi anofukidzawo mhepo inopinda mu emulsion, zvichiita firimu remvura rakasimba, uye pamusoro pemvura, firimu remamorekuru rakaita sebilayer. Izvi zvinodzivirira zvikuru kuputsika kwefuro.
Furo kuunganidzwa kwemabubbles akawanda, nepo bubble rinoumbwa kana gasi rikapararira mumvura—gasi sechikamu chakapararira uye mvura sechikamu chinoenderera mberi. Gasi riri mukati memabubbles rinogona kufamba kubva kune rimwe bubble kuenda kune rimwe kana kutiza richipinda mumhepo yakapoteredza, zvichikonzera kubatana kwemabubbles uye kunyangarika.
Pamvura yakachena kana ma surfactants chete, nekuda kwekugadzirwa kwawo kwakafanana, furo rinobuda harina kusimba, zvichiita kuti furo risagadzikane uye rizvibvise roga. Dzidziso yeThermodynamic inoratidza kuti furo rinogadzirwa mumvura yakachena nderenguva pfupi uye rinonyangarika nekuda kwekubuda kwemvura mufirimu.
Sezvambotaurwa, mumachira anogadzirwa nemvura, kunze kwemvura inopararira, kunewo maemulsifier epolymer emulsification, pamwe chete nema dispersants, wetting agents, thickeners, nezvimwe zvinowedzera machira anogadzirwa ne surfactant. Sezvo zvinhu izvi zvichigara pamwe chete musystem imwe chete, kuumbwa kwefuro kunogona kuitika, uye zvinhu izvi zvakaita se surfactant zvinowedzera kudzikamisa furo rinogadzirwa.
Kana ma "ionic surfactants" achishandiswa se "emulsifiers", firimu re "bubble film" rinowana chaji yemagetsi. Nekuda kwekudzora kwakasimba pakati pe "charges", ma "bubbles" anoramba kuungana, zvichidzivisa maitiro e "bubbles" diki kuti dzibatanidzwe kuita "hombe" dzobva dzadonha. Nekuda kweizvozvo, izvi zvinodzivisa kubviswa kwe "furo" uye zvinoita kuti furo rigare rakagadzikana.
