Ni ukubera iki kwiyongera kwimitekerereze ya surfactant biganisha kumubyimba mwinshi?

Iyo umwuka winjiye mumazi, kubera ko udashonga mumazi, igabanyijemo ibibyimba byinshi n'amazi munsi y'imbaraga zo hanze, bigakora sisitemu itandukanye. Umwuka umaze kwinjira mumazi ugakora ifuro, agace gahuza gazi namazi kiyongera, kandi ingufu zubusa za sisitemu nazo zirazamuka bikurikije.

Ingingo yo hasi ihuye nibyo dukunze kwita nkibintu bikomeye bya micelle yibanze (CMC). Kubwibyo, iyo kwibanda kwa surfactant bigeze kuri CMC, haba hari umubare uhagije wa molekile ya surfactant muri sisitemu kugirango ihuze cyane hejuru y’amazi, ikora firime ya monomolecular idafite icyuho. Ibi bigabanya sisitemu yo hejuru. Iyo ubushyuhe bwo hejuru bugabanutse, ingufu zubusa zisabwa kubyara ifuro muri sisitemu nazo ziragabanuka, bigatuma ifuro ryoroha cyane.

Mubikorwa bifatika no kubishyira mubikorwa, kugirango hamenyekane ihame rya emulisiyo zateguwe mugihe cyo kubika, kwibanda kwa surfactant bikunze guhinduka hejuru yibitekerezo bya micelle. Mugihe ibi byongera imbaraga za emulsion, bifite kandi ibibi. Gukabya gukabya gukabije ntigabanya gusa uburemere bwubuso bwa sisitemu ahubwo binatwikiriye umwuka winjira muri emulsiyo, bigakora firime isa naho ikomeye, kandi hejuru y’amazi, firime ya bilayeri. Ibi birabuza cyane gusenyuka.

Ifuro ni igiteranyo cyibibyimba byinshi, mugihe igituba kiba iyo gaze ikwirakwijwe mumazi - gaze nkicyiciro cyatatanye hamwe namazi nkicyiciro gikomeza. Umwuka wa gaze imbere urashobora kwimuka uva mubindi byinshi cyangwa guhungira mu kirere gikikije, biganisha ku guhurira hamwe no kubura.

Ku mazi meza cyangwa surfactants yonyine, bitewe nuburyo bugereranije, firime yavuyemo ibura idafite ubuhanga, bigatuma ifuro ridahungabana kandi rikunda kwikuramo. Thermodynamic theory yerekana ko ifuro ikomoka mumazi meza ari iyigihe gito kandi igatandukana kubera amazi ya firime.

Nkuko byavuzwe haruguru, mumazi ashingiye kumazi, usibye gukwirakwiza amazi (amazi), hariho na emulifisiferi ya polymer emulisifike, hamwe nogukwirakwiza, imiti itose, kubyimba, nibindi byongeweho bishingiye kubutaka. Kubera ko ibyo bintu bibana muri sisitemu imwe, birashoboka cyane ko habaho ifuro, kandi ibyo bintu bisa nkibishobora kongera ifuro ryakozwe.

Iyo ionic surfactants ikoreshwa nka emulisiferi, firime ya bubble ibona amashanyarazi. Bitewe no kwangwa gukabije hagati yumuriro, ibituba birwanya kwegeranya, guhagarika inzira yibibyimba bito bihuza binini hanyuma bigasenyuka. Kubwibyo, ibi bibuza kurandura ifuro kandi bigahindura ifuro.
