Sei kuwedzera kweiyo surfactant concentration kunotungamirira mukunyanya kuumbwa kwefuro?

Kana mhepo ichipinda mumvura, sezvo isinganyungudika mumvura, inopatsanurwa kuita mabhuru akawanda nemvura iri pasi pesimba rekunze, ichigadzira heterogeneous system. Kana mweya wangopinda mumvura uye uchiita furo, nzvimbo yekubatana pakati pegasi uye mvura inowedzera, uye simba remahara rehurongwa rinokwirawo saizvozvo.

Iyo yakaderera poindi inoenderana nezvatinowanzo daidza kuti yakakosha micelle concentration (CMC). Naizvozvo, kana iyo surfactant yekumisikidza yasvika kuCMC, kune huwandu hwakakwana hwemamorekuru e surfactant musystem kuti aenderane zvine mutsindo pamusoro pemvura, achigadzira gap-isina monomolecular film layer. Izvi zvinoderedza tension yesystem. Kana kushushikana kwepamusoro kuchidzikira, simba remahara rinodiwa pakugadzira furo muhurongwa zvakare rinodzikira, zvichiita kuti kuumbwa kwefuro kuve nyore.

Mukuita kugadzirwa uye kushandisa, kuve nechokwadi kugadzikana kweakagadzirirwa emulsions panguva yekuchengetedza, iyo surfactant yekumisikidza inowanzo gadziridzwa pamusoro peiyo yakakosha micelle concentration. Kunyange izvi zvichisimudzira emulsion kugadzikana, ine zvakare zvimwe zvinokanganisa. Yakawandisa surfactants haingoderedze kushushikana kwepasi pasi asi zvakare kufukidza mhepo inopinda mu emulsion, ichigadzira firimu rakaomarara remvura, uye pamusoro pemvura, bhaisikopo rema molecular. Izvi zvinokanganisa zvakanyanya kuputsika kwefuro.

Furo muunganidzwa wemafuro akawanda, nepo bhavhu rinoumbwa kana gasi raparadzirwa mumvura—gasi sechikamu chakaparadzirwa uye mvura sechikamu chinoramba chichienderera. Iyo gasi iri mukati memabhuru inogona kutama ichibva kune rimwe bubble ichienda kune imwe kana kutizira mumhepo yakatenderedza, zvichitungamira mukubatanidzwa kwebubble uye kunyangarika.

Kumvura yakachena kana ma surfactants ega, nekuda kwechimiro chayo chakafanana, iyo inoguma furo firimu inoshaya elasticity, zvichiita kuti furo risagadzikane uye riite nyore kuzvibvisa. Thermodynamic theory inoratidza kuti furo rinogadzirwa muzvinwiwa zvakachena nderenguva pfupi uye rinoparara nekuda kwemvura yemufirimu.

Sezvambotaurwa, mumabhati emvura, kunze kwekuparadzira svikiro (mvura), kune zvakare emulsifiersfor polymer emulsification, pamwe nemadisperants, wetting agents, thickeners, uye zvimwe surfactant-based coating additives. Sezvo zvinhu izvi zvichigara muhurongwa humwe chete, kuumbwa kwefuro kunobvira zvikuru, uye zvinhu izvi zvakaita sesurfactant zvinowedzera kudzikamisa furo rakagadzirwa.

Kana ionic surfactants inoshandiswa se emulsifiers, bubble film inowana magetsi emagetsi. Nekuda kwekuramba kwakasimba pakati pemachaji, mabubbles anoramba kuunganidzwa, achidzvanya maitiro emabhuru madiki achibatana kuita makuru obva adonha. Nekuda kweizvozvo, izvi zvinodzivirira kubviswa kwefuro uye kudzikamisa furo.

Taura nesu!
