Muraho! Nkumuntu utanga emulifier, nkunze kubazwa kubyerekeye indangagaciro za HLB za emulisiferi zitandukanye. Noneho, reka twibiremo neza turebe niba emulisiferi zitandukanye zifite agaciro ka HLB zitandukanye.
Icyambere, HLB ni iki? HLB bisobanura Hydrophilique - Impirimbanyi ya Lipophilique. Ni igipimo kidufasha kumva uburyo emulifiyeri yitwara mu ruvange rw'amazi n'amavuta. Igipimo cya HLB kiri hagati ya 0 na 20. Agaciro gake HLB (0 - 3) bivuze ko emulifisiyeri ari lipofilique (amavuta - gukunda), mugihe agaciro ka HLB (17 - 20) byerekana ko ari hydrophilique (amazi - gukunda).
Noneho, iyo bigeze kuri emulisiferi zitandukanye, igisubizo ni yego rwose, bafite indangagaciro zitandukanye za HLB. Kandi ibi nibyingenzi cyane kuko HLB agaciro ka emulifier irashobora kumenya imikorere yayo mubikorwa bitandukanye.
Reka turebe bimwe mubisanzwe emulisiferi hamwe nagaciro ka HLB. Imwe muribyiza - bizwi na emulisiferi ni Span 20. Ifite agaciro ka HLB hafi 8.6. Span 20 ni lipofilique, ituma biba byiza kurema amazi - muri em - amavuta (W / O). Ubu bwoko bwa emulisiyo bukoreshwa mubintu nka cream n'amavuta yo kwisiga aho ushaka ko amavuta aba icyiciro gikomeza.
Kurundi ruhande, dufite hagati ya 80. Hagati ya 80 ifite agaciro ka HLB kangana na 15. Ni hydrophilique, bityo rero ni byiza gukora amavuta - muri em {em- amazi (O / W). O / W emulisiyo ikunze kuboneka mubicuruzwa nko kwambara salade n'amata, aho amazi aricyiciro gikomeza.
Impamvu emulisiferi zitandukanye zifite indangagaciro zitandukanye za HLB zishira kumiterere yimiti. Emulifisiyeri igizwe na hydrophilique na lipofilique. Ikigereranyo cyibi bice byombi kigena agaciro ka HLB. Kurugero, emulifier ifite itsinda rinini rya hydrophilique hamwe nitsinda rito rya lipofilique izaba ifite agaciro gakomeye ka HLB, mugihe imwe ifite itsinda rinini rya lipofilique hamwe nitsinda rito rya hydrophilique izaba ifite agaciro ka HLB.
Ariko kuki bitwaye ko emulisiferi zitandukanye zifite indangagaciro zitandukanye za HLB? Nibyiza, niba utegura ibicuruzwa, ugomba guhitamo emulifier ikwiye hamwe nagaciro keza ka HLB kubyo ukeneye byihariye. Reka tuvuge ko ukora izuba. Imirasire y'izuba ikubiyemo amazi n'amavuta. Ukeneye emulisiferi ifite agaciro ka HLB ishobora gukora emulisiyo ihamye ya O / W kugirango izuba ryizuba rikwirakwira byoroshye kuruhu kandi ntiritandukane. Niba uhisemo emulifier ifite agaciro ka HLB itari yo, emulion irashobora gucika, kandi ibicuruzwa byawe ntibikora nkuko byateganijwe.
Ikindi kintu ugomba gusuzuma ni uko rimwe na rimwe, ushobora gukenera gukoresha imvange ya emulisiferi kugirango ugere ku gaciro HLB wifuza. Ibi byitwa sisitemu ya emulifier. Muguhuza emulisiferi ebyiri cyangwa nyinshi hamwe nagaciro ka HLB, urashobora neza - guhuza muri rusange HLB ya sisitemu. Kurugero, niba ukeneye emulifier ifite agaciro ka HLB ya 10, ukaba ufite emulisiferi imwe hamwe na HLB ya 8 indi ifite HLB ya 12, urashobora kubivanga muburyo bukwiye kugirango ubone agaciro wifuza.
Noneho, ndashaka kuvuga umutungo ushimishije rwose ushobora kuguha byinshi muri - amakuru yimbitse kubyerekeye emulisiferi no kugerageza kwabo. Urashobora kugenzura4-testdfgsdfg. Ifite amakuru akomeye nubushishozi bushobora kugufasha kumva neza emulisiferi.
Nkumuntu utanga emulisiferi, nabonye ubwanjye akamaro ko guhitamo emulisiferi nziza hamwe nagaciro ka HLB. Dutanga ibyiciro byinshi bya emulisiferi hamwe nagaciro ka HLB kugirango duhuze ibyifuzo bitandukanye byabakiriya bacu. Waba uri mu nganda zibiribwa, kwisiga, cyangwa urundi rwego rusaba emulisiyo, twagutwikiriye.
Niba muri iki gihe uri muburyo bwo gukora ibicuruzwa bishya cyangwa ushaka kunoza igihari, kubona emulifier ikwiye ni ngombwa. Kandi aho niho tuza. Itsinda ryinzobere zacu zirashobora kugufasha guhitamo emulifier nziza ukurikije ibyo usabwa byihariye. Twunvise ko ibicuruzwa byose bidasanzwe, kandi twiyemeje kuguha - emulisifike nziza cyane izemeza neza ibyo wakoze.
Noneho, niba ushishikajwe no kwiga byinshi kubyerekeranye na emulisiferi cyangwa ufite ikibazo kijyanye n'indangagaciro za HLB hamwe na emulisiferi ikubereye, ntutindiganye kubigeraho. Turi hano kugirango tuganire, dusubize ibibazo byawe, kandi tugufashe kubona igisubizo cyiza cya emulifier. Waba uri muto - utanga urugero cyangwa uruganda runini -, dushobora gukorana nawe kugirango uhuze ibyifuzo bya emulifier.
Mu gusoza, emulisiferi zitandukanye zifite indangagaciro zitandukanye za HLB, kandi izo ndangagaciro zigira uruhare runini mumikorere ya emulisiyo mubicuruzwa bitandukanye. Mugusobanukirwa igitekerezo cya HLB ugahitamo emulifier ikwiye, urashobora gukora ibicuruzwa bihamye, bihanitse - ibicuruzwa byiza. Kandi nkumutanga wawe wizewe wa emulifier, twiteguye kugutera intambwe zose. Noneho, reka dutangire uru rugendo hamwe kandi ibicuruzwa byawe bibe byiza!
