Ukuba ufuna ukuphuhlisa iimveliso ze-amino acid surfactant, ungacinga ngokusebenzisa ii-amphoteric okanye ii-non-ionic surfactants ezinamandla okuzinzisa i-foam kunye ne-foam.

Umzobo wamandla okufutha kunye namandla okufutha azinzileyo e-surfactant efanayo:

 
Yintoni i-surfactant?

I-surfactant yikhompawundi equlathe ubuncinane iqela elinye elibalulekileyo le-surface affinity kwi-molecule yayo (ukuqinisekisa ukunyibilika kwamanzi kwiimeko ezininzi) kunye neqela elingelolasini apho kungekho buhlobo buninzi khona. Ii-surfactants ezisetyenziswa rhoqo zii-ionic surfactants (kuquka ii-cationic surfactants kunye nee-anionic surfactants), ii-non-ionic surfactants, ii-amphoteric surfactants.
Isiqalisi somphezulu sesona sithako siphambili sesepha yokufutha. Indlela yokukhetha isiqalisi somphezulu esisebenza kakuhle ivavanywa ngokwemilinganiselo emibini yokusebenza kwefoam kunye namandla okususa amafutha. Phakathi kwazo, ukulinganiswa kokusebenza kwefoam kubandakanya izalathiso ezimbini: ukusebenza kwefoam kunye nokusebenza kozinzo lwefoam.

Ukulinganiswa kweempawu zefoam

Yintoni esiyikhathaleleyo ngamaqamza?

Kunjalo nje, ingaba ikhupha amagwebu ngokukhawuleza? Ngaba kukho igwebu elininzi? Ngaba igwebu liza kuhlala ixesha elide?
Le mibuzo siza kuyifumana iimpendulo ekumiselweni nasekuhlolweni kwezinto eziluhlaza

Emva kokuvavanya nokurekhoda, idatha yayo iboniswa ngolu hlobo lulandelayo:
 

 
Ngokuthelekisa nokuhlela, singayicoca ngokukhawuleza i-surface activator enekhono elihle lokufutha, size sifumane nomthetho wokufutha kwe-surface activator: (ps: Ngenxa yokuba izinto ezifanayo eziluhlaza zivela kubavelisi abahlukeneyo, ukusebenza kwayo kwe-foam nako kwahlukile, apha sebenzisa oonobumba abakhulu abahlukeneyo ukumela abavelisi abahlukeneyo bezinto eziluhlaza)

① Phakathi kwezinto ezisebenzisa i-surfactants, i-sodium lauryl glutamate inamandla amakhulu okufutha, kwaye i-disodium lauryl sulfosuccinate inamandla amancinci okufutha.

② Uninzi lwee-sulfate surfactants, ii-amphoteric surfactants kunye nee-non-ionic surfactants zinamandla okuzinzisa i-foam, ngelixa ii-amino acid surfactants zihlala zinamandla okuzinzisa i-foam. Ukuba ufuna ukuphuhlisa iimveliso ze-amino acid surfactant, ungacinga ngokusebenzisa ii-amphoteric okanye ii-non-ionic surfactants ezinamandla okuzinzisa i-foam kunye ne-foam.
 
Umzobo wamandla okufutha kunye namandla okufutha azinzileyo e-surfactant efanayo:
 

I-sodium lauryl glutamate

I-Ammonium lauryl sulfate

Akukho nxibelelwano phakathi kokusebenza kwe-foam kunye nokusebenza kwe-foam ukuzinzisa kwe-surfactant efanayo, kwaye ukusebenza kwe-foam ukuzinzisa kwe-surfactant kunye nokusebenza kwe-foam okuhle kusenokungabi kuhle.
Ukuthelekiswa kozinzo lwe-bubble ye-surfactant eyahlukeneyo:

 
Ps: Izinga lotshintsho oluhambelanayo = (ukuphakama kwefoam kwimizuzu eyi-0 – ukuphakama kwefoam kwimizuzu engama-60)/ukuphakama kwefoam kwimizuzu eyi-0
Iikhrayitheriya zovavanyo: Okukhona izinga lotshintsho oluhambelanayo liphezulu, kokukhona amandla okuzinzisa amaqamza eba buthathaka
Ngokuhlalutya itshathi yebhamuza, kunokugqitywa kwelokuba:

① I-Disodium cocamphoamphodiacetate inamandla okuqinisa i-foam, ngelixa i-lauryl hydroxyl sulfobetaine inamandla okuqinisa i-foam.

② Amandla okuzinzisa i-foam kwi-lauryl alcohol sulfate surfactants ngokubanzi alungile, kwaye amandla okuzinzisa i-amino acid kwi-anionic surfactants ngokubanzi aphantsi;

Isalathiso soyilo lwefomula:

Kungagqitywa ngokusebenza kokusebenza kwe-foam kunye nokusebenza kozinzo lwe-foam kwi-activator yomphezulu ukuba akukho mthetho uthile kunye nolwalamano phakathi kwezi zimbini, oko kukuthi, ukusebenza kakuhle kwe-foam akusoloko kukuko ukusebenza okuhle kozinzo lwe-foam. Oku kusenza ukuba ekuhlolweni kwezinto eziluhlaza ze-surfactant, kufuneka sicinge ngokunika ukusebenza okugqwesileyo kwe-surfactant, indibaniselwano efanelekileyo yeentlobo ngeentlobo ze-surfactant, ukuze kufumaneke ukusebenza kakuhle kwe-foam. Kwangaxeshanye, idityaniswe ne-surfactants enamandla okususa i-greasing ukuze kufezekiswe isiphumo sokucoca zombini iipropati ze-foam kunye namandla okususa i-greasing.

Uvavanyo lwamandla okususa amafutha:

Injongo: Ukuhlola izinto ezivuselela umphezulu ezikwaziyo ukukhulula ukuxinana, nokufumanisa ulwalamano phakathi kweempawu zefoam kunye namandla okususa amafutha ngokuhlaziya nokuthelekisa.
Iikhrayitheriya zovavanyo: Sithelekise idatha yee-pixels zamabala zelaphu lefilimu ngaphambi nasemva kokucoca umphezulu we-activator, sabala ixabiso lokuhamba, saza senza i-degreasing power index. Okukhona i-index iphezulu, kokukhona amandla okucoca anamandla.
 

 
Kuyabonakala kwidatha engentla ukuba phantsi kweemeko ezichaziweyo, amandla aqinileyo okususa amafutha yi-ammonium lauryl sulfate, kwaye amandla abuthathaka okususa amafutha yi-CMEA ezimbini;
Kungagqitywa kwidatha yovavanyo engentla ukuba akukho nxibelelwano ngqo phakathi kweempawu ze-foam ze-surfactant kunye namandla ayo okususa amafutha. Umzekelo, ukusebenza kwe-foam ye-ammonium lauryl sulfate enamandla okususa amafutha akulunganga. Nangona kunjalo, ukusebenza kwe-foam ye-C14-16 olefin sodium sulfonate, enamandla okususa amafutha aphantsi, iphambili.
 

Kutheni ke ngoko ukuba iinwele zakho zinamafutha amaninzi, kokukhona zingabi nagwebu kangako? (Xa usebenzisa ishampu efanayo).

Enyanisweni, le yinto eqhelekileyo. Xa uhlamba iinwele zakho ngeenwele ezinamafutha amaninzi, igwebu liyancipha ngokukhawuleza. Ngaba oku kuthetha ukuba ukusebenza kwegwebu kubi? Ngamanye amazwi, ngaba ukusebenza kwegwebu kungcono, kokukhona amandla okususa amafutha angcono?
Sele siyazi ngokwedatha efunyenwe ngolu vavanyo ukuba ubungakanani befoam kunye nokuqina kwefoam kuxhomekeka kwiimpawu zefoam ze-surfactant ngokwayo, oko kukuthi, iimpawu zokukhupha ifoam kunye neempawu zozinzo lwefoam. Amandla okususa ukungcola kwe-surfactant ngokwayo akayi kuphelelwa ngamandla kukunciphisa ifoam. Eli nqaku likwabonakalisiwe xa sigqibile ukumisela amandla okususa ioyile ye-surface activator, i-surface activator eneempawu zefoam ezilungileyo isenokungabi namandla okususa ioyile, kwaye ngokuchaseneyo.
 
Ukongeza, singabonisa ukuba akukho nxibelelwano luthe ngqo phakathi kwe-foam kunye ne-surfactant degreasing kwimigaqo yokusebenza eyahlukeneyo yezi zimbini.
 
Umsebenzi we-surfactant foam:

I-Foam luhlobo lwe-arhente esebenzayo kumphezulu phantsi kweemeko ezithile, indima yayo ephambili kukunika inkqubo yokucoca amava akhululekileyo namnandi, kulandele ukucocwa kweoyile kudlala indima yokuncedisa, ukuze ioyile ingabi lula ukuyihlalisa kwakhona phantsi kwesenzo sefoam, ihlanjwe lula.
 
Umgaqo wokwenza i-surfactant igwebu kwaye isuse amafutha:
Amandla okucoca e-surfactant avela kubuchule bayo bokunciphisa uxinzelelo phakathi kwe-oyile namanzi (ukususa amafutha), endaweni yokunciphisa uxinzelelo phakathi kwamanzi nomoya (ukwenza igwebu).
Njengoko besitshilo ekuqaleni kweli nqaku, ii-surfactants ziimolekyuli eziphila emanzini abandayo, enye yazo iphila emanzini abandayo kwaye enye iphila emanzini abandayo. Ke ngoko, xa kugxilwe kakhulu, i-surfactant ihlala phezu kwamanzi, apho isiphelo se-lipophilic (esithiya amanzi) sijonge ngaphandle, kuqala sigqume umphezulu wamanzi, oko kukuthi, ujongano lwamanzi nomoya, ngaloo ndlela sinciphise uxinzelelo kule ndawo.

Nangona kunjalo, xa uxinzelelo lugqitha inqaku, i-surfactant iya kuqala ukuqokelelana, yenze ii-micelles, kwaye uxinzelelo lwe-interfacial alusayi kuphinda lwehle. Olu xinzelelo lubizwa ngokuba yi-critical micelle concentration.
 

 
Amandla okufutha ama-surfactants alungile, nto leyo ebonisa ukuba anamandla okunciphisa uxinzelelo phakathi kwamanzi nomoya, kwaye isiphumo soxinzelelo oluphantsi phakathi kwamanzi kukuba ulwelo ludla ngokuvelisa iindawo ezingaphezulu (ummandla wonke womphezulu weqela lamaqamza mkhulu kakhulu kunowamanzi azolileyo).
Amandla okucoca i-surfactant akwikhono layo lokumanzisa umphezulu webala kunye nokulixuba, oko kukuthi, "ukugquma" ioyile kwaye ivumele ukuba ixube kwaye ihlanjwe ngamanzi.
 
Ngoko ke, amandla okucoca i-surfactant adibene nokukwazi kwayo ukusebenzisa i-oyile-water interface, ngelixa amandla okucoca i-foam emele kuphela amandla ayo okusebenzisa i-water-air interface, kwaye ezi zimbini azinxulumananga ngokupheleleyo. Ukongeza, kukwakho nezihlanzi ezininzi ezingafaki i-foam, ezifana ne-makeup remover kunye ne-makeup remover oil esetyenziswa kakhulu kubomi bethu bemihla ngemihla, nazo zinamandla okucoca i-foam, kodwa akukho foam iveliswayo, kwaye kuyacaca ukuba i-foam kunye ne-decoration azifani.
 
Ngokumisela nokuhlola iimpawu zefoam ze-surfactant ezahlukeneyo, sinokufumana ngokucacileyo i-surfactant eneempawu zefoam eziphezulu, emva koko ngokumisela nokulandelelana kwamandla okususa amafutha e-surfactant, kufuneka sisuse amandla okungcola e-surfactant. Emva kokudityaniswa, nika amandla apheleleyo kwiingenelo ze-surfactants ezahlukeneyo, wenze ii-surfactants zigqibelele kwaye zisebenze kakuhle, kwaye ufumane isiphumo sokucoca esigqwesileyo kunye namava okusebenzisa. Ukongeza, sikwaqonda kumgaqo wokusebenza we-surfactant ukuba i-foam ayinxulumananga ngokuthe ngqo namandla okucoca, kwaye olu lwazi lunokusinceda ukuba sibe nokugweba kwethu kunye nokuqonda xa sisebenzisa i-shampoo, ukuze sikhethe imveliso efanelekileyo kuthi.
