Mfundo yapepala lopaka mafuta odzolazimachokera makamaka pa zochitika ziwiri zakuthupi: kutsatsa ndi kulowetsa. pa
Choyamba, mfundo ya adsorption ndi yakuti pamwamba pa pepala lopaka mafuta limakhala ndi lipophilicity, yomwe imalola kuti mafuta awonongeke pamapepala. Adsorption ndi zochitika zakuthupi zomwe zimachitika chifukwa cha chinthu chomwe chimadutsa pamwamba pa adsorbent. Pamwamba pa adsorbent imakhala ndi malo akuluakulu enieni komanso ntchito inayake yamankhwala, ndipo imatha kukopa zinthu zozungulira. Ulusi wa pepala lomwe limayamwa mafuta ndi lobowoka ngati nsungwi, ndipo mawonekedwe ndi pamwamba pa lumen ndizosiyana. Kukula kwapamtunda, kumapangitsanso mphamvu ya adsorb mafuta. Ulusiwu umakhala ndi hydrophobic ndi lipophilic properties, zomwe zimathandiza kuti pepala lopaka mafuta lizitha kuyamwa bwino mafuta pamwamba pa nkhope. pa
Chachiwiri, mfundo kulowerera ndi kutipepala lopaka mafutanthawi zambiri imatenga njira yopangira pansi kuti ikhale yoyenera, ndikupanga capillary kanthu, kuti pepala likhale ndi mawonekedwe olowera. Mphamvu ya capillary ya pepalayo imalola kuti mafutawo agawidwe mofanana mu ulusi wapapepala, ndi kufalikira mkati mwa capillary ya pepala lozungulira. pa
Mwachidule, pepala lopaka mafuta odzola limachotsa bwino mafuta ochulukirapo a nkhope pogwiritsa ntchito mawonekedwe a adsorption ndi kulowa mkati, kusunga khungu labwino komanso loyera.
