② Ikhono lokuzinzisa igwebu le-lauryl alcohol sulfate surfactants ngokuvamile lihle, futhi ikhono lokuzinzisa igwebu lama-amino acid anionic surfactants ngokuvamile alilungile;

Ireferensi yedizayini yefomula:

Kungaphethwa ngokusebenza kokusebenza okunamagwebu nokusebenza kokuqinisa igwebu kwe-activator engaphezulu ukuthi awukho umthetho othile nokuhlobana phakathi kwakho kokubili, okungukuthi, ukusebenza kahle kwegwebu akuwona ngempela ukusebenza kokuzinzisa kwegwebu.Lokhu kusenza ukuthi sihlole izinto zokusetshenziswa ezisetshenziswayo, kufanele sicabangele ukunikeza ukudlala okuphelele ekusebenzeni okuhle kakhulu kwe-surfactant, inhlanganisela enengqondo yezinhlobonhlobo ze-surfactant, ukuze sithole ukusebenza kahle kwegwebu.Ngasikhathi sinye, kuhlanganiswe nama-surfactants anamandla okukhipha amafutha aqinile ukuze kuzuzwe umphumela wokuhlanza wazo zombili izakhiwo zegwebu namandla okwehlisa.

Ukuhlolwa kwamandla okwehlisa amafutha:

Inhloso: Ukuhlola iziqalisi ezingaphezulu ezinekhono eliqinile lokuqeda ukuhlangana, kanye nokuthola ubudlelwano phakathi kwezakhiwo zegwebu namandla okwehlisa amafutha ngokuhlaziya nokuqhathanisa.
Imibandela yokuhlola: Siqhathanise idatha yamaphikseli angamabala endwangu yefilimu ngaphambi nangemuva kokususwa kokungcola kwe-activator engaphezulu, sabala inani lokuhamba, futhi sakha inkomba yamandla anciphayo.Uma inkomba iphakeme, amandla okwehlisa amafutha anamandla.
 

 
Kungabonakala kudatha engenhla ukuthi ngaphansi kwezimo ezishiwo, amandla aqinile okukhipha amafutha yi-ammonium lauryl sulfate, futhi amandla okukhipha amafutha abuthakathaka ama-CMEA amabili;
Kungaphethwa ngedatha yokuhlola engenhla ukuthi akukho ukuhlobana okuqondile phakathi kwezakhiwo zegwebu le-surfactant namandla ayo okwehlisa amafutha.Isibonelo, ukusebenza kwegwebu le-ammonium lauryl sulfate enamandla okwehlisa amafutha akukuhle.Kodwa-ke, ukusebenza okunegwebu kwe-C14-16 olefin sodium sulfonate, enamandla amancane okwehlisa amafutha, kuhamba phambili.
 

Pho kungani izinwele zakho zinamafutha kakhulu, ziyancipha amagwebu?(Uma usebenzisa i-shampoo efanayo).

Eqinisweni, lokhu kuyisenzakalo sendawo yonke.Uma ugeza izinwele zakho ngezinwele ezinamafutha, igwebu liyancipha ngokushesha.Ingabe lokhu kusho ukuthi ukusebenza kwegwebu kubi?Ngamanye amazwi, ingabe kungcono ukusebenza kwegwebu, ngcono ikhono lokwehlisa amafutha?
Sesivele sazi emininingwaneni etholwe ekuhloleni ukuthi ubuningi begwebu nokuqina kwegwebu kunqunywa izici zegwebu ze-surfactant ngokwayo, okungukuthi, izakhiwo zokugwebu kanye nezakhiwo zokuzinzisa igwebu.Ikhono lokuqeda ukungcola kwe-surfactant ngokwayo ngeke lenziwe buthaka ngokuncishiswa kwegwebu.Leli phuzu liphinde lafakazelwa lapho sesiqedile ukunqunywa kwekhono lokunciphisa amafutha e-activator engaphezulu, i-activator engaphezulu enezici ezinhle zegwebu ingase ingabi namandla amahle okukhipha amafutha, futhi ngokuphambene nalokho.
 
Ukwengeza, singafakazela futhi ukuthi akukho ukuhlobana okuqondile phakathi kwegwebu kanye nokukhishwa kwe-surfactant kusuka ezimisweni zokusebenza ezihlukene zazo zombili.
 
Umsebenzi wegwebu le-surfactant:

I-Foam iwuhlobo lwe-ejenti esebenzayo ngaphansi kwezimo ezithile, indima yayo eyinhloko ukunikeza inqubo yokuhlanza isipiliyoni esikhululekile nesijabulisayo, okulandelwa ukuhlanzwa kwamafutha kudlala indima yokusiza, ukuze amafutha angabi lula ukuxazulula futhi ngaphansi. isenzo segwebu, sigezwe kalula.
 
Isimiso sokukhihliza amagwebu kanye nokukhishwa kwamafutha kwe-surfactant:
Amandla okuhlanza osebenza emanzini avela ekhonweni lalo lokunciphisa ukungezwani kobuso bukawoyela namanzi (ukwehlisa), kunamandla okunciphisa ukungezwani phakathi kobuso bamanzi komoya (ukucweba).
Njengoba sishilo ekuqaleni kwalesi sihloko, ama-surfactants angama-amphiphilic molecule, enye yawo i-hydrophilic kanti enye i-hydrophilic.Ngakho-ke, ekugxilweni okuphansi, i-surfactant ivame ukuhlala phezu kwamanzi, kanti isiphetho se-lipophilic (ukuzonda amanzi) sibheke ngaphandle, kuqala simboze ubuso bamanzi, okungukuthi, isixhumi esibonakalayo somoya, futhi ngaleyo ndlela sinciphisa. ukushuba kwesixhumi esibonakalayo.

Kodwa-ke, uma ukugxilisa ingqondo kudlula iphoyinti, i-surfactant izoqala ukuhlangana, yakhe ama-micelles, futhi ukungezwani kobuso ngeke kuphinde kwehle.Lokhu kugxila kubizwa ngokuthi i-critical micelle concentration.
 

 
Amandla okwenza amagwebu ama-surfactants mahle, okubonisa ukuthi anamandla aqinile okunciphisa ukungezwani phakathi kwamanzi nomoya, futhi umphumela wokuncipha kokuqina kobuso ukuthi uketshezi luvame ukukhiqiza izindawo eziningi (ingqikithi yendawo yonke yenqwaba. amabhamuza makhulu kakhulu kunawamanzi azolile).
Amandla okukhipha ukungcola kwe-surfactant asemandleni akhe okumanzisa ibala lebala futhi alifake, okungukuthi, "ukugqoka" amafutha futhi avumele ukuba afakwe emulsified futhi ageze emanzini.
 
Ngakho-ke, ikhono lokukhipha ukungcola komuntu osebenza emanzini lixhunyaniswe nekhono layo lokwenza kusebenze isixhumi esibonakalayo samanzi kawoyela, kuyilapho amandla okugwebu amele kuphela amandla okuvula isixhumi esibonakalayo somoya, futhi kokubili akuhlobene ngokuphelele.Ngaphezu kwalokho, kukhona nezihlanzi eziningi ezingenagwebu, ezifana ne-makeup remover kanye namafutha e-makeup remover avame ukusetshenziswa empilweni yethu yansuku zonke, anekhono eliqinile lokuqeda ukungcola, kodwa alikho igwebu elikhiqizwayo, futhi kusobala ukuthi igwebu kanye nokungcola. azifani.
 
Ngokunqunywa nokuhlolwa kwezakhiwo zegwebu ze-surfactant ehlukene, singathola ngokucacile i-surfactant enezici eziphakeme zegwebu, bese kuthi ngokunquma nokulandelana kwamandla okwehlisa amafutha e-surfactant, kufanele sisuse ikhono lokungcolisa le-surfactant.Ngemuva kwalokhu kuhlanganiswa, nikeza umdlalo ogcwele izinzuzo zama-surfactants ahlukene, yenza ama-surfactants asebenze kakhudlwana futhi asebenze kahle kakhulu, futhi uthole umphumela wokuhlanza osezingeni eliphezulu nolwazi lokusebenzisa.Ngaphezu kwalokho, siyaqaphela futhi ngesimiso sokusebenza se-surfactant ukuthi igwebu alihlobene ngokuqondile namandla okuhlanza, futhi lokhu kuqonda kungasisiza ukuba sibe nokwahlulela kwethu siqu kanye nokuqonda lapho sisebenzisa ishampu, ukuze sikhethe umkhiqizo osifanelekelayo.
