Yini izakhiwo ze-surficasternts?

Yehlisa ukungezwani komhlaba

Ukunciphisa ukungezwani komhlaba kuwumsebenzi oyisisekelo kakhulu weAma-Surfactants. Kukhona ukungezwani kwe-macroscopic kungqimba ye-liquid ye-liquid eyenza indawo yoketshezi ihlehlise ubuncane ngangokunokwenzeka, okungukuthi, ukungezwani komhlaba. Ngemuva kokungeza ama-surfactants, ama-surfactants akha ifilimu elincanyana ebusweni boketshezi, eshintsha ukuhlelwa kwamangqamuzana komhlaba, ngaleyo ndlela anciphise ukungezwani komhlaba.

IMicelles ibhekisa ku-Aggregates yama-molecule aqala ukwakha ngobuningi kwikhambi lamanzi ngemuva kokuhlushwa okuqhubekayo.

Ama-surfactants ancibilikisiwe emanzini. Lapho ukugxila kwabo kuphansi, zihlakazeka njengamangqamuzana angashadile noma ama-adsorbed ngaphezulu kwesixazululo ukuze anciphise ukungezwani komhlaba. Lapho ukugcwala kwama-surfactants kukhuphuka kuze kube seqophelweni lokuthi ingaphezulu lekhambi ligcwele futhi ngeke kusaba ama-adsorbed, ama-molecule weAma-Surfactantsqala ukudlulela ngaphakathi kwesixazululo. Ngoba ingxenye ye-hydrophobic ye-molecule eqinile enobudlelwano obuncane enamanzi, kanti ukuheha phakathi kwezingxenye ezithile ze-hydrophilic kukhulu, lapho izingxenye ezithile ze-hydrophilic zikhulu, lapho izingxenye ezithile ze-hydrophobic zingama-molecule amaningi (ngokuvamile zingu-150) zihlenge umzimba wenhlangano, okungukuthi yiMicelles. IMicelles inezimo ezahlukahlukene, ezinjenge-spherical, lamellar, ne-rod ebunjiwe.
