Waa maxay astaamaha surwadka?

Yaree xiisadda dusha sare

Yaraynta xiisadda dusha sare ayaa ah shaqada ugu aasaasiga ah eesurfacts. Waxaa jira xiisad macroscopic ah oo ah lakabka dusha sare ee dareeraha ka dhiga dusha sare ee dareeraha ah inay u yaraato ugu yaraan intii ugu yar ee suuragalka ah, taasi waa xiisadda dusha sare, xiisadda dusha sare. Ka dib markii lagu daro surwaal, surfacts waxay sameeyaan filim khafiif ah oo ku yaal dusha sare ee dareeraha, beddelashada qaab-dhismeedka molikariga ee dusha sare ee dareeraha, taas oo ay ku dhimaysaa xiisadda dusha sare.

Sameynta mickeles

Micelles wuxuu tixraacayaa isku-darka isku-darka moleekulada ee bilaabaya inay ku sameeyaan tiro aad u badan oo ah xalka aqueous ka dib markii ay ku celcelisku ka soo baxdo qiime cayiman.

Surfacladaha ayaa lagu kala diraa biyaha. Markay u fiirsanayso, waxaa loo kala firdhiyaa sidii hal molecules keliya ama ku xajiya dusha sare ee xalka si loo yareeyo xiisadda dusha sare. Markii ay uruurineyso sarkaalku kordho meesha dusha sare ee xalka xalka lagu buufiyo oo aan mar dambe lagu qancin karin, moleekuladasurfactsBilow inaad u guurto gudaha xalka. Sababta oo ah qaybta biyaha ee molileelka sagxaduhu waxay ku leedahay mid yar oo biyo ah, halka soojiidashada ka dhexeysa qaybo ka mid ah moleecules-ka badan ee dusha sare ah (guud ahaan 150) oo is dhagaysta si ay u sameeyaan hay'ad urur, oo ah mocelles. Micelles waxay leeyihiin qaabab kala duwan, sida laf-dhabarta, Lamellar, iyo udgoon-qaabeeya.
