Okukhona i-foam ingcono, ingcono isakhono sokucoca?

Sazi kangakanani malunga neemveliso zokucoca ezinogwebu esizisebenzisa yonke imihla?Ngaba siye sazibuza: yintoni indima ye-foam kwizinto zangasese?

Kutheni sikhetha ukukhetha iimveliso ezinamagwebu?

 

 
 
Ngokuthelekisa kunye nokuhlelwa, singakwazi ngokukhawuleza ukukhupha i-activator engaphezulu kunye nekhono elihle lokugwebu, kwaye sifumane nomthetho ophuphumayo we-activator yomhlaba: (ps: Ngenxa yokuba imathiriyeli ekrwada efanayo ivela kubavelisi abohlukeneyo, ukusebenza kwayo kogwebu kwahlukile, apha. sebenzisa oonobumba abakhulu abahlukeneyo ukumela imathiriyeli ekrwada eyahlukeneyoabavelisi)

①Phakathi kwe-surfactants, i-lauryl glutamate yesodium inamandla ogwebu olomeleleyo, kwaye i-disodium lauryl sulfosuccinate inamandla okufoma amagwebu.

② Uninzi lwee-surfactants zesulfate, ii-amphoteric surfactants kunye nee-non-ionic surfactants zinamandla okuqina amagwebu, ngelixa i-amino acid surfactants ngokubanzi inamandla obuthathaka okuqina kogwebu.Ukuba ufuna ukuphuhlisa iimveliso ze-amino acid surfactant, unokuqwalasela ukusebenzisa i-amphoteric okanye ii-non-ionic surfactants ezinogwebu olomeleleyo kunye nekhono lokuzinzisa ugwebu.

Umzobo wamandla agwebu amagwebu kunye namandla azinzileyo abilayo e-surfactant efanayo:

 
Yintoni i-surfactant?

I-surfactant yikhompawundi equlathe ubuncinci iqela elibalulekileyo lobudlelwane bomphezulu kwimolekyuli yayo (ukuqinisekisa ukunyibilika kwayo emanzini kwiimeko ezininzi) kunye neqela elingabelana ngesondo elinobudlelwane obuncinci kulo.Ii-surfactants ezisetyenziswa ngokuqhelekileyo zi-ionic surfactants (kuquka i-cationic surfactants kunye ne-anionic surfactants), i-non-ionic surfactants, i-amphoteric surfactants.
I-activator engaphezulu sesona sithako singundoqo sesixhobo sokucoca ugwebu.Indlela yokukhetha i-activator yomhlaba esebenza kakuhle ivavanywa kwimilinganiselo emibini yokusebenza kwegwebu kunye namandla okunciphisa.Phakathi kwabo, umlinganiselo wokusebenza kwe-foam uquka izalathisi ezimbini: ukusebenza kwegwebu kunye nokusebenza kokuqina kwe-foam.

Umlinganiselo weempawu ze-foam

Yintoni esiyikhathaleleyo ngamaqamza?

Yiyo nje, ngaba iqamza ngokukhawuleza?Ngaba kukho ugwebu oluninzi?Ingaba iqamza liya kuhlala?
Le mibuzo siya kufumana iimpendulo ekumiselweni nasekuhlolweni kwezixhobo ezikrwada

Umzobo wamandla agwebu amagwebu kunye namandla azinzileyo abilayo e-surfactant efanayo:
 

I-sodium lauryl glutamate

I-ammonium lauryl sulfate

Akukho lunxulumano phakathi kokusebenza kogwebu kunye nokusebenza kozinziso logwebu lwe-surfactant efanayo, kunye nokusebenza kozinzo lwegwebu lwe-surfactant kunye nokusebenza kakuhle kogwebu lusenokungabi luhle.
Ukuthelekiswa kozinzo lweqamza lwe-surfactant eyahlukeneyo:

 
I-Ps: Umlinganiselo wokutshintsha okuhambelanayo = (ukuphakama kwe-foam kwi-0min - ukuphakama kwe-foam kwi-60min) / ukuphakama kwe-foam kwi-0min
Iikhrayitheriya zoVavanyo: Xa usiba mkhulu umlinganiselo wotshintsho, kokukhona uba buthathaka amandla okuzinzisa iqamza
Ngohlalutyo lwetshathi yeqamza, kunokugqitywa ukuba:

① I-Disodium cocamphoamphodiacetate inamandla okuzinzisa ugwebu, ngelixa i-lauryl hydroxyl sulfobetaine inobona buchule bubuthathaka bokuzinzisa ugwebu.

② Amandla okuzinzisa ugwebu lwe-lauryl alcohol sulfate surfactants lulungile jikelele, kunye nesakhono sokuzinzisa ugwebu lwe-amino acid anionic surfactants siqhelekile;

Isalathiso soyilo lwefomula:

Kunokuqukunjelwa ngokusebenza kokusebenza kogwebu kunye nokusebenza kozinzo lwe-foam ye-activator yomhlaba ukuba akukho mthetho uthile kunye nolungelelwaniso phakathi kwezi zinto zimbini, oko kukuthi, ukusebenza kakuhle kogwebu akuyomfuneko ukuba kusebenze ukuzinzisa kwamagwebu.Oku kusenza ukuba sivavanye imathiriyeli ekrwada ye-surfactant, kufuneka sicinge ngokudlala ngokupheleleyo ekusebenzeni okugqwesileyo kwe-surfactant, indibaniselwano enengqiqo yeentlobo ngeentlobo ze-surfactant, ukuze sifumane ukusebenza kogwebu olugqibeleleyo.Kwangaxeshanye, idityaniswe kunye ne-surfactants enegunya elinamandla lokuthoba ukufezekisa umphumo wokucoca zombini iipropathi ze-foam kunye namandla okunciphisa.

Uvavanyo lokunciphisa amandla:

Injongo: Ukuhlola ii-activators zomphezulu ezinesakhono esomeleleyo sokuthomalalisa, kunye nokufumana ubudlelwane phakathi kwepropathi yogwebu kunye namandla okwehlisa igrisi ngokuhlalutya kunye nokuthelekisa.
Iikhrayitheriya zokuvavanya: Sithelekise idatha yeepikseli zebala lelaphu lefilimu ngaphambi nangemva kwe-activator ye-surface activator decontamination, sibale ixabiso lokuhamba, kwaye senze isalathisi samandla okunciphisa.Ukuphakama kwesalathisi, amandla okunciphisa amandla.
 

 
Inokubonwa kule datha ingentla ukuba phantsi kweemeko ezichaziweyo, amandla anamandla okunciphisa i-ammonium lauryl sulfate, kwaye amandla okunciphisa abuthathaka yi-CMEA ezimbini;
Inokugqitywa kwidatha yovavanyo engentla ukuba akukho kulungelelaniswa ngokuthe ngqo phakathi kweempawu ze-foam ze-surfactant kunye namandla ayo okunciphisa.Umzekelo, ukusebenza kwe-foam ye-ammonium lauryl sulfate enamandla okunciphisa amandla akulunganga.Nangona kunjalo, ukusebenza kogwebu lwe-C14-16 olefin sodium sulfonate, enamandla okunciphisa amandla, iphambili.
 

Ke kutheni le nto iinwele zakho zinamafutha, kokukhona zingabi namagwebu?(Xa usebenzisa ishampu efanayo).

Enyanisweni, le yinto eyenzeka kwihlabathi jikelele.Xa uhlamba iinwele zakho ngeenwele ezinamafutha, i-foam iyancipha ngokukhawuleza.Ngaba oku kuthetha ukuba ukusebenza kwamagwebu kubi?Ngamanye amazwi, ngaba ngcono ukusebenza kwegwebu, ngcono isakhono sokuthoba?
Sele sisazi kwidatha efunyenwe ngovavanyo lokuba ubuninzi be-foam kunye nokuqina kwe-foam kugqitywe yimpahla ye-foam ye-surfactant ngokwayo, oko kukuthi, iipropathi ezinogwebu kunye neempawu zokuzinzisa amagwebu.Amandla okuphelisa ukungcola kwe-surfactant ngokwawo awayi kuba buthathaka ngokuncitshiswa kwegwebu.Eli nqaku libonakaliswe kwakhona xa sigqibe ukuzimisela kokunciphisa amandla e-activator yangaphandle, i-activator ye-surface activator eneempawu ezintle ze-foam ayinakuba namandla okunciphisa kakuhle, kwaye ngokuphambene noko.
 
Ukongeza, sinokungqina ukuba akukho kulungelelaniswa ngokuthe ngqo phakathi kwegwebu kunye ne-surfactant degreasing ukusuka kwimigaqo yokusebenza eyahlukeneyo kwezi zimbini.
 
Umsebenzi we-foam ye-surfactant:

I-Foam luhlobo lwe-agent esebenzayo phantsi kweemeko ezithile, indima yayo ephambili kukunika inkqubo yokucoca i-coffeeness kunye namava amnandi, kulandelwa ukucocwa kweoli kudlala indima encedisayo, ukuze ioli ingabi lula ukuhlalisa kwakhona phantsi. isenzo sogwebu, sihlanjwe ngokulula ngakumbi.
 
Umgaqo wokukhupha amagwebu kunye nokukhutshwa kwegrisi kwi-surfactant:
Amandla okucoca i-surfactant avela kubuchule bawo bokunciphisa i-oyile-amanzi aphakathi kwe-facial tension (degreasing), kunokuba akwazi ukucutha unxunguphalo lwamanzi-lomoya (ugwebu).
Njengoko sitshilo ekuqaleni kweli nqaku, i-surfactants yi-amphiphilic molekyuli, enye yazo i-hydrophilic kwaye enye i-hydrophilic.Ngoko ke, kwiindawo eziphantsi, i-surfactant idla ngokuhlala phezu kwamanzi, kunye nesiphelo se-lipophilic (ukuthiya amanzi) sijonge ngaphandle, kuqala sigqume umphezulu wamanzi, oko kukuthi, ujongano lomoya wamanzi, kwaye ngaloo ndlela sinciphisa. Uxinzelelo kolu jongano.

Nangona kunjalo, xa i-concentration idlula inqaku, i-surfactant iya kuqalisa ukuhlanganisana, yenze ii-micelles, kwaye i-interfacial tension ayisayi kuphinda yehle.Olu gxininiso lubizwa ngokuba lugxininiso olubalulekileyo lwemicelle.
 

 
Isakhono sokugwebu se-surfactants sihle, nto leyo ebonisa ukuba inamandla awomeleleyo okunciphisa ukutshayisana kobuso phakathi kwamanzi nomoya, kwaye isiphumo sokuncitshiswa koxinzelelo oluphakathi kobuso kukuba ulwelo luthanda ukuvelisa imiphezulu engaphezulu (indawo epheleleyo yomphezulu weqela amaqamza makhulu kakhulu kunamanzi azolileyo).
Amandla okutshatyalaliswa kwe-surfactant alele ekukwazini ukumanzisa umphezulu webala kwaye awufake, oko kukuthi, "ukugqoka" ioli kwaye uyivumele ukuba ifakwe emulsified kwaye ihlanjwe emanzini.
 
Ke ngoko, amandla okuphelisa ungcoliseko lwe-surfactant inxulunyaniswe namandla akhe okwenza ujongano lwamanzi e-oyile lusebenze, ngelixa amandla ogwebu amele kuphela ukukwazi kwawo ukwenza ujongano lomoya lwamanzi lusebenze, kwaye ezi zimbini azizalani ngokupheleleyo.Ukongeza, kukho ezininzi izicoci ezingenagwebu, ezifana ne-makeup remover kunye ne-oyile yokususa i-makeup esetyenziswa rhoqo kubomi bethu bemihla ngemihla, ekwanamandla okuphelisa iintsholongwane, kodwa akukho gwebu luveliswayo, kwaye kuyacaca ukuba igwebu kunye ne-decontamination. aziyonto enye.
 
Ngokumisela kunye nokuhlolwa kweempawu zogwebu ze-surfactant eyahlukileyo, sinokufumana ngokucacileyo i-surfactant eneempawu eziphezulu zogwebu, kwaye ngokumisela kunye nolandelelwano lwamandla okunciphisa i-surfactant, kufuneka sisuse isakhono songcoliseko se-surfactant.Emva kolu hlanganiso, nika umdlalo ogcweleyo kwiingenelo zee-surfactants ezahlukeneyo, yenza i-surfactants igqibelele ngakumbi kwaye isebenze ngokugqwesileyo, kwaye ufumane isiphumo sokucoca esigqwesileyo kunye namava okusebenzisa.Ukongeza, siyaqonda kwakhona kumgaqo wokusebenza we-surfactant ukuba i-foam ayihambelani ngokuthe ngqo kumandla okucoca, kwaye oku kuqonda kunokusinceda ukuba sibe nombono wethu kunye nokuqonda xa sisebenzisa ishampu, ukuze sikhethe imveliso efanelekileyo kuthi.
