Ukumanzisa kwenzeka lapho into eqinile ihlangana noketshezi. Izixhumi zokuqala zegesi eqinile kanye negesi ewuketshezi ziyanyamalala, bese kwakheka isixhumi esisha segesi eqinile. Isibonelo, imicu yendwangu iyizinto ezinezimbobo ezinendawo enkulu ethile. Lapho isixazululo sisakazeka eduze kwemicu, singena ezikhaleni eziphakathi kwemicu bese sisusa umoya, siphendule isixhumi sokuqala se-air-fiber sibe isixhumi se-liquid-fiber.—Lena inqubo evamile yokumanzisa. Okwamanje, ikhambi lingena ngaphakathi kwemicu, inqubo eyaziwa ngokuthi ukungena. Ama-surfactant enza kube lula ukumanzisa nokungena abizwa ngokuthi ama-wetting agents kanye nama-penetrate agents ngokulandelana.
Ukuhlanganiswa kwe-Emulsification
Amafutha anomfutho ophezulu wobuso emanzini. Uma uwoyela ufakwa emanzini futhi ingxube ivuselelwa ngamandla, uwoyela uyaqhekeka abe amaconsi amancane ukuze akhe i-emulsion, kodwa ingxube izophinde ihlukane ibe yizingqimba uma ukuxuba kuyeka. Uma kufakwa i-surfactant futhi ingxube ivuselelwa, izingqimba ngeke zihlukane kalula isikhathi eside ngemva kokuxuba kuyeka, okuyi-emulsification. Ingxenye yama-molecule kawoyela e-hydrophobic izungezwe amaqembu e-surfactants athanda amanzi, okudala amandla akhangayo aqondisa isiqondiso. Lokhu kunciphisa amandla adingekayo ukusabalalisa uwoyela emanzini futhi kufeza i-emulsification ephumelelayo yamafutha.
Ngenxa yomphumela wokuxubha wama-surfactants, izinhlayiya zikawoyela nokungcola ezikhishwe ezindaweni eziqinile zingaxubhaniswa kahle futhi zihlakazeke ezixazululweni zamanzi, zivimbele ukuthi zingaphinde zifakwe ezindaweni ezihlanziwe futhi zibangele ukungcola.
Ukuhlakazeka kubhekisela enkambisweni lapho izinto eziqinile ezinganyibiliki zisakazwa khona esixazululweni njengezinhlayiya ezincane ukuze kwakheke ukumiswa. Izinto ezithuthukisa ukuhlakazeka kwezinto eziqinile futhi zigcine ukumiswa okuzinzile zibizwa ngokuthi ama-dispersant. Empeleni, kunzima ukuhlukanisa i-emulsification nokuhlakazeka lapho uwoyela oqinile uhlanganiswa futhi uhlakazwa ezixazululweni. Njengoba ama-emulsifier nama-dispersant ngokuvamile ewuhlobo olufanayo lwento, abizwa ngokuthi ama-emulsifier-dispersant ekusetshenzisweni okungokoqobo.
Ukuncibilika kusho ukuthi ama-surfactant angandisa ukuncibilika kwezinto ezingancibiliki noma ezingancibiliki emanzini. Isibonelo, ukuncibilika kwe-benzene emanzini kungu-0.09% ngevolumu. Ngemva kokufaka ama-surfactant njenge-sodium oleate, ukuncibilika kwe-benzene kungakhuphuka kufike ku-10%.
Ukuncibilika kuhlobene kakhulu nama-micelles akhiwe ama-surfactant emanzini. I-micelle iyinhlanganisela eyakhiwe lapho amaketanga e-hydrocarbon ama-molecule e-surfactant esondelana esisombululo samanzi ngenxa yokusebenzisana kwe-hydrophobic. Ingaphakathi le-micelle empeleni liyi-hydrocarbons ewuketshezi, ngakho-ke izinyibilikisi ezingezona ezi-polar organic ezingancibiliki emanzini, njenge-benzene kanye namafutha amaminerali, zingancibilika kalula ngaphakathi kwama-micelles. Ukuncibilika kuwukuncibilika kwezinto ezi-lipophilic yi-micelles, okuyisici esiyingqayizivele sama-surfactants. Kuqala ukusebenza kuphela lapho ukunqwabelana kwe-surfactant esisombululoni kudlula ukunqwabelana kwe-critical micelle (CMC), okungukuthi lapho inani elikhulu lama-micelles amakhulu likhona. Ngaphezu kwalokho, ama-micelles amakhulu anikeza amandla amakhulu okuncibilika.
Ukuncibilika kuhlukile ekuncibilikeni. Ukuncibilika kukhiqiza uhlelo lwezigaba eziningi olungaqhubeki futhi olungazinzile lapho isigaba esisodwa soketshezi sihlakazeka emanzini noma kwesinye isigaba soketshezi. Ngokuphambene nalokho, ukuncibilika kuphumela ohlelweni lwesigaba esisodwa oluqinile nolulinganayo lapho isisombululo sokuncibilika kanye nento encibilikayo zikhona esigabeni esifanayo. Uhlobo olulodwa lwe-surfactant lungaba nezakhiwo zokuncibilika kanye nezokuncibilika, kodwa ukuncibilika kwenzeka kuphela lapho ukuncibilika kwalo kungaphezu kokuncibilika kwe-micelle ebalulekile.
Uma ama-molecule e-surfactant eqondana ngqo ezindaweni zendwangu, anciphisa i-coefficient yokungqubuzana okungaguquki kwezindwangu. Ama-surfactant angewona ama-ionic afana nama-linear alkyl polyoxyethylene polyols kanye nama-linear alkyl fatty acid polyoxyethylene ethers, kanye nama-cationic surfactants ahlukahlukene, anganciphisa i-static friction coefficient yezindwangu futhi ngaleyo ndlela asebenze njengezinto zokuthambisa indwangu. Kodwa-ke, ama-surfactant anamaqembu e-branched alkyl noma ama-aromatic ayahluleka ukwakha ilungiselelo elihlelekile lokuqondisa ezindaweni zendwangu ngakho-ke awafaneleki ukusetshenziswa njengezithambisi.
