Imiterere yaibikoresho by'ubwubatsibyoroshye cyane: impera imwe irapfa amazi (amazi‑gukunda) n'indi itera lipophilic (amavuta‑gukunda). Buri mpera ifatanye n'amazi n'amavuta. Molekile za surfactant ziteranira kuri peteroli‑Uburyo amazi ahuriramo, kandi ibyo ni byo bigize imiterere y'ibanze. Emulsification ni imwe mu nshingano z'ibinyabutabire, nyamara ni yo ikoreshwa cyane‑ikoreshwa mu nganda zacu. Ikoreshwa cyane cyane mu kuvanga amazi‑amavuta akomoka kuri shimi, nk'amavuta ya emulsified n'amazi‑irimo umuriro‑amazi arwanya hydraulic. Mu by'ukuri, ariko, emulsifiers zigira akamaro kanini cyane mu buzima bwa buri munsi‑ibintu bizima birimo amata, urubura‑amavuta yo kwisiga na shampoo, byose birimo ibintu bigabanya ubushyuhe ku rugero rutandukanye.
Kubera iyi miterere yoroheje ya molekile, ibintu byinshi bigaragaza imiterere igabanya ubukana bw'ibinyabutabire, bigatuma guhitamo ibinyabutabire birushaho kuba byiza. Dushobora kuvuga ko tudasobanukiwe neza ibinyabutabire, umuntu ntashobora gukora amazi yujuje ibisabwa.‑Ibikoresho by'amavuta bishingiye ku mavuta. Birazwi ko amavuta n'amazi bidahinduka. Bityo rero, hakenewe emulsifiers kugira ngo zihuzwe. Muri uku guhuzwa gukomeye, igice kimwe kizahindukamo udutonyanga duto tw'amazi mu gihe ikindi gitonyanga gitwikira ibyo bitonyanga byuzuye. Ibi bibyara igitekerezo cy'icyiciro gikomeza n'icyiciro gitatanye: igice kimwe gicibwamo udutonyanga tudakomeza naho ikindi kigakora igikoresho gikomeza kidahinduka. Mu buryo bwa macroscopic, ibi bitanga amazi yombi.‑in‑amavuta (W/O) cyangwa amavuta‑in‑emulsion z'amazi (O/W). Ibyo bikubiyemo amahame shingiro y'inyunganizi.
Iyoemulsifieryinjizwa mu mavuta adahinduka‑Uburyo bwo gukwirakwiza amazi, hashyirwaho uburyo bushya bwo kuvanga ibice bibiri. Ibi si ugushonga kw'ukuri mu buryo bw'uko umunyu ushonga mu mazi. Ahubwo, igice kimwe gikwirakwira kimwe nk'ibitonyanga bito mu kindi gice. Iyo imiterere yo hanze ihindutse, amavuta n'amazi bizongera gutandukana, bigaragaza ko gushonga nabi cyangwa kudakomera neza kwa emulsion. Inyongera zimwe na zimwe zishobora guhungabanya amavuta‑Kunganya amazi no gutera gutandukana kw'icyiciro cyose; ibintu nk'ibi bikora binyuranyije n'ibintu bigabanya ubushyuhe kandi bizwi nka demulsifiers.
Emulsion mu by'ukuri ni uburyo bwo gukwirakwiza. Bitewe no gukwirakwiza‑Ibitonyanga by'itsinda n'itandukaniro ry'urumuri rugaragara hagati y'itsinda, urumuri rw'impanuka runyura mu mucyo, rugakwirakwira no koherezwa ku buso bw'ibitonyanga. Ingano isanzwe y'ibitonyanga bya emulsion iri hagati ya 0.1μkuva kuri m kugeza kuri 10μm, mu gihe bigaragara‑uburebure bw'urumuri buri hagati ya 0.4μm na 0.6μm. Kugaragara cyane bibaho, bigatuma emulsions zisa n'amata‑isura y'umweru. Iyo umurambararo w'ibitonyanga uri hagati ya 0.05μm kugeza kuri 0.1μm (ni ntoya gato kurusha uko bigaragara‑uburebure bw'urumuri), urumuri rurakwirakwira kandi sisitemu isa n'aho ibonerana. Ku ngano y'ibitonyanga biri munsi ya 0.05μm (nto cyane kurusha uko bigaragara‑uburebure bw'urumuri), uburyo bwo kohereza urumuri buraganza kandi sisitemu irabonerana. Sisitemu zifite ingano y'ibitonyanga biri munsi ya 0.1μm zisa n'izibonerana cyangwa zibonerana zisobanurwa nk'imikoro, imiterere yazo itandukanye cyane n'imikoro isanzwe. Microemulsion iracyari emulsion, gusa ifite utunyangingo twinshi dutandukanye.‑Ibitonyanga by'itsinda. Iremwa ryabyo ntabwo risaba gusa emulsifiers ahubwo rinasaba‑emulsifiers. Ibi bigaragaza ko emulsification‑itwarwa"gusenyuka"mu by'ukuri bishingira ku kugenzura ingano y'uduce tw'igice gitatanye.
Imikorere ya emulsifier ishingiye ku buringanire bworoshye. Ubushobozi bwayo bwo gukurura amazi n'ubwo gukurura lipophilic bugira ingaruka nziza. Urugero, urugero, hasi‑Alkoholi za karuboni zigaragaza ubushobozi bukomeye bwo gushonga no gushonga mu mazi kandi zishongesha mu mazi zifite amavuta make cyane. Ibinyuranye n'ibyo, ibintu bikabije bigabanya ubukana bw'amavuta ntibishobora gukorana n'amazi kandi bigaragaza amavuta.‑imyitwarire yo gushonga. Nubwo ibintu byinshi bifite ibice bikunda amazi n'ibikunda lipophilic, ntibishobora gushyirwa mu byiciro bya surfactants. Iyo ikintu gikunda amazi cyangwa lipophilic cyane, ni ubuso gusa.‑ikintu gikora, kimwe na bimwe mu byongewemo byavuzwe haruguru. Igipimo gipimirwa ku bijyanye n'amazi‑imbaraga zikomoka kuri lipophilic zirakenewe rero, ni ukuvuga iriba‑uzwi nka Hydrophile‑Lipophile‑Agaciro k'ifaranga risigaye (HLB).

Gukurura amavuta mu buryo busanzwe ukoresheje imashini zikurura amavuta ntabwo bigoye cyane. Ubwoko bwiza bwa emulsifier, ingano n'imiterere y'ubudahangarwa bishobora kugaragazwa mu buryo bw'igerageza binyuze mu igerageza.‑na‑ikosa. Bityo iterambere rya emulsifier rishingiye cyane ku bikorwa by'igerageza. Ingano nyinshi za micro‑Kugeza uyu munsi, abashakashatsi ntibarasobanukirwa neza uburyo ibintu bikorwamo n’abahanga. Uretse emulsification, surfactants zitanga uburyo bwo gukaraba, gusukura, gukwirakwiza, gushonga n’ibindi bikorwa. Ku nganda zacu, gusuzuma igerageza ni uburyo bufatika, kuko ubumenyi nyakuri buturuka mu bikorwa. Amategeko menshi yashyizweho mu buryo bw’igerageza: emulsifiers zivanze zirusha emulsifiers imwe, hamwe n’uruvange rwa anionic na non‑ionic surfactants itanga ingaruka nziza ku bufatanye.
Nubwo inyigisho ya emulsifier isa n'iyoroshye, kuyikoresha mu buryo bufatika biragoye. Gukoresha emulsifiers byonyine bishobora gukemurwa binyuze mu igerageza, nyamara byinshi muri byo nyuma yaho‑inyongeramusaruro zifite ubuso‑Imiterere ikora. Ibi bibangamira imikorere ya emulsifier kandi bigahindura HLB ikora neza ya sisitemu. Urugero rusanzwe ni imiti igabanya ingese muri emulsifier. Iyi miterere ifite uburebure bwinshi‑ibintu bikora birimo mu gukumira ingese ariko bishobora kwangiza amavuta‑Kugereranya amazi mu buryo busanzwe kandi bigomba kubarwa mu gihe cyo guhitamo emulsifier. Gukora uruvange rw'ubwoko bwinshi bwa emulsifier bishobora kugabanya urugero n'ikiguzi mu gihe bikongera ubudahinduka bwa emulsion. Ariko, ibibazo bijyanye no guhuza emulsifier zitandukanye n'uburyo bwo kuvanga byazo byongera cyane imiterere y'imvange. Igitekerezo gihoraho kivuga ko emulsifier za anionic na cationic zidashobora kuvangwa. Mu by'ukuri, anionic‑Uruvange rw'ibinyabutabire bya cationic ruvugwa cyane mu bumenyi bw'ibinyabutabire, nubwo bidakunze gukoreshwa mu rwego rwacu. Iyoni za kalisiyumu na manyeziyumu ziba mu mazi akomeye zishobora no kwangiza filime za emulsion interfacial no guhagarika emulsifiers. Iyoni za kalisiyumu ni ikibazo gikomeye: inyinshi mu zinyabutabire za surfactant zigira ingaruka kuri kalisiyumu kugira ngo zikore amazi.‑isabune ya kalisiyumu idashonga isohoka mu mubiri. Iyi ngingo izaganirwaho mu gice gikurikira.
Bityo, emulsifier zisa n'izoroshye ziba ingorabahizi cyane iyo izindi ngingo zishyizwemo. Gukora emulsion irangiye ntabwo bigoye; ikibazo nyacyo kiri mu kubungabunga ubusugire mu bihe bitandukanye byo gukora, gukomeza guhuza amavuta n'amazi buri gihe.
