I-Sodium Laureth Sulfate CAS 3088-31-1

I-Sodium Laureth Sulfate CAS 3088-31-1 Ulwazi

Okomzimba
Ukubukeka: I-sodium laureth sulfate evamile iwuketshezi lwe-viscous olungenambala noma oluphuzi olukhanyayo, lokhu kuthungwa kwe-viscous kubangelwa ukusebenzisana kwe-intermolecular, njenge-hydrogen bonding, ebuye inqume ukuthi idinga ukushintshwa ukuze ivumelane nemishini ethile ekupakisheni nasekuthuthweni ukuze kuvinjelwe izinsalela nokuvala. .
I-Solubility: Ine-solubility enhle kakhulu yamanzi, ngenxa yengxenye ye-polyether chain kanye neqembu le-sulfonic acid esakhiweni se-molecular, engenziwa ngokushesha i-ionized emanzini ukuze yakhe i-anion ezinzile, okwenza yonke i-molecule ihlakazeke kalula emanzini ukuze yakhe i-ayoni ecacile futhi eqinile. isixazululo esisobala, esilungele ukusetshenziswa ezinhlelweni ezihlukahlukene zefomula esekwe emanzini.
Iphuzu elincibilikayo kanye nokuminyana: Njengoba iwuketshezi, akusho lutho ukukhuluma ngendawo yokuncibilika; Ukuminyana kwayo ngokuvamile kuphakeme kancane kunokwamanzi, phakathi kuka-1.05 no-1.08 g/cm³, futhi idatha yokuminyana isiza ukubala ngokunembile ivolumu nokuguqulwa kwenqwaba phakathi nokuhlanganisa nomthamo.

Izakhiwo zamakhemikhali
I-Surfactant: Njenge-surfactant enamandla, inciphisa ngokuphawulekayo ukushuba kwesimo samanzi. Uma engezwa emanzini, ama-molecule azofuduka ngokuzenzakalelayo aye esixhumi esibonakalayo somoya, kanti isiphetho se-hydrophobic sifinyelela emoyeni futhi isiphetho se-hydrophilic sisele emanzini, kuphazamise ukuhlelwa kwasekuqaleni kwama-molecule amanzi, okwenza kube lula ukuthi amanzi asabalale. futhi imanzi ezindaweni eziqinile, ngaleyo ndlela ithuthukise ikhono lokuhlanza, i-emulsify, igwebu, njll.
Ukuzinza: Ingagcina ukuqina okuhle kwamakhemikhali ebangeni le-pH elibanzi (ngokuvamile i-pH 4 – 10), okuyenza ifaneleke ezinhlobonhlobo zokwakheka komkhiqizo ezindaweni ezihlukene ze-asidi-alkali, kodwa ngaphansi kwesenzo sesikhathi eside sama-asidi aqinile nama-alkali. , i-hydrolysis kanye nokubola kungase kwenzeke, kuthinte ukusebenza.
Ukusebenzelana nezinye izinto: uma ihlangana nama-surfactants e-cationic, izokwakha imvula ngenxa yokukhanga kweshaji futhi ilahlekelwe umsebenzi wayo ongaphezulu; Kodwa-ke, uma ihlanganiswa namanye ama-anionic kanye nama-nonionic surfactants, ingavamisile ukuvumelanisa ukuze kuthuthukiswe ukusebenza kahle kokuhlanza nokusebenza okunamagwebu kokwakheka.

Indlela yokulungiselela:
Ngokuvamile, i-lauryl alcohol isetshenziswa njengento yokuqala, futhi ukusabela kwe-ethoxylation kwenziwa kuqala, futhi izinombolo ezihlukene zamayunithi e-ethylene oxide ziyethulwa ukuthola i-laureth. Kamuva, ngemva kwezinyathelo ze-sulfonation kanye ne-neutralization, i-laureth polyester iphathwa ngama-sulfonating agents njenge-sulfur trioxide, bese ihlukaniswa ngokungeza i-sodium hydroxide ukuze ekugcineni ilungiselele i-sodium laureth sulfate. Yonke inqubo ilawulwa ngokuqinile izinga lokushisa lokuphendula, ingcindezi kanye nesilinganiso sezinto ezibonakalayo, futhi ikhwalithi yomkhiqizo izothinteka uma kukhona umehluko omncane echibini.

sebenzisa
Imikhiqizo yokunakekelwa komuntu siqu: Kuyisithako esiyinhloko emikhiqizweni yokuhlanza efana nama-shampoos, amajeli okugeza, nama-sanitizers esandla, anesibopho sokukhiqiza i-lather ecebile neminyene ukuze kube nesipiliyoni sokusebenzisa okujabulisayo, kuyilapho isusa ngamandla amafutha nokungcola esikhumbeni nasezinweleni. , eshiya abasebenzisi bezizwa beqabulekile futhi behlanzekile.
Izihlanzi zasendlini: Emikhiqizweni yokuhlanza yasendlini njengensipho yezitsha nokowasha izingubo, amandla e-SLES okuhlanza aphezulu kanye nokuncibilika kahle kwamanzi kusiza ukususa amabala anenkani ezitsheni nasezimpahleni, kanye nezakhiwo zakhona ezikhipha amagwebu futhi zingasiza abasebenzisi ukuthi bahlulele izinga lokuhlanzeka.
Ukuhlanzwa kwezimboni: Kwezinye izimo zezimboni, njengokuhlanza insimbi nokuhlanza imoto, kuphinde kusize ukususa ukungcola okufana nowoyela nothuli futhi kuthuthukise ukusebenza kahle kokuhlanza kanye nekhwalithi ngamakhono ako avelele okukhipha ukungcola kanye ne-emulsification.
