I-Sodium Laureth Sulfate CAS 3088-31-1

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

Ngokwasemzimbeni
Imbonakalo: I-sodium laureth sulfate eqhelekileyo ilulwelo olungenambala okanye olukhanyayo lwe-viscous olumthubi, lo mfanekiso we-viscous uvela kwintsebenziswano ye-intermolecular, efana ne-hydrogen bonding, ekwamisela ukuba kufuneka iguqulelwe kwisixhobo esithile sokupakisha kunye nokuthutha ukuthintela iintsalela kunye nokuvala. .
I-Solubility: Ine-solubility egqwesileyo yamanzi, ngenxa yecandelo le-polyether chain kunye neqela le-sulfonic acid kwisakhiwo se-molecular, enokuthi i-ionized ngokukhawuleza emanzini ukuze yenze i-anion ezinzileyo, eyenza i-molecule yonke ihlakazeke ngokulula emanzini ukuze yenze ngokucacileyo kwaye isisombululo esicacileyo, esilungele ukusetyenziswa kwiinkqubo ezahlukeneyo zefomula esekwe emanzini.
Iqondo lokunyibilika kunye noxinaniso: Kuba ilulwelo, akukho kubaluleka kancinci ukuthetha ngendawo yokunyibilika; Ubuninzi bayo buphezulu kancinane kunobo bamanzi, phakathi kwe-1.05 kunye ne-1.08 g/cm³, kwaye idatha yoxinaniso inceda ukubala ngokuchanekileyo umthamo kunye nokuguqulwa kobunzima ngexesha lokuqulunqa kunye nedosi.

Iimpawu zeMichiza
I-Surfactant: Njenge-surfactant enamandla, inciphisa ngokuphawulekayo ukuxinana komphezulu wamanzi. Xa zongezwa emanzini, iimolekyuli ziya kufuduka ngokuzenzekelayo kwi-interface yamanzi omoya, kunye nesiphelo se-hydrophobic sifikelela emoyeni kunye nesiphelo se-hydrophilic esisele emanzini, siphazamisa ulungelelwaniso oluqinileyo lweeamolekyuli zamanzi, okwenza kube lula ukuba amanzi asasazeke. kwaye imanzi kwiindawo eziqinileyo, ngaloo ndlela iphucula ukukwazi ukucoca, i-emulsify, i-foam, njl.
Ukuzinza: Inokugcina uzinzo oluhle lweekhemikhali kwi-pH ebanzi (ngokuqhelekileyo i-pH 4 - 10), eyenza ukuba ifaneleke kwiintlobo ezahlukeneyo zemveliso kwiindawo ezahlukeneyo ze-asidi-alkali, kodwa phantsi kwesenzo sexesha elide le-acids eqinile kunye ne-alkali. , i-hydrolysis kunye nokubola kunokwenzeka kwakhona, kuchaphazela ukusebenza.
Ukusebenzisana nezinye izinto: xa idibana ne-cationic surfactants, iya kwenza i-precipitate ngenxa yokutsala umtsalane kwaye ilahlekelwe ngumsebenzi wayo ongaphezulu; Nangona kunjalo, xa idityaniswe nezinye i-anionic kunye ne-nonionic surfactants, inokuhlala idibanisa ukuze iqhubekisele phambili ukucoca kunye nokusebenza kwegwebu lokuqulunqwa.

Indlela yokulungiselela:
Ngokuqhelekileyo, i-lauryl alcohol isetyenziswa njengento yokuqala, kwaye impendulo ye-ethoxylation iqhutyelwa kuqala, kwaye amanani ahlukeneyo eeyunithi ze-ethylene oxide aziswa ukufumana i-laureth. Emva koko, emva kwamanyathelo e-sulfonation kunye ne-neutralization, i-laureth polyester iphathwa nge-sulfonating agents ezifana ne-sulfur trioxide, kwaye ingathathi hlangothi ngokongeza i-sodium hydroxide ekugqibeleni ilungiselele i-sodium laureth sulfate. Yonke le nkqubo ilawulwa ngokungqongqo ngokusabela ubushushu, uxinzelelo kunye nomlinganiselo wezinto eziphathekayo, kwaye umgangatho wemveliso uya kuchaphazeleka ukuba kukho umahluko omncinane echibini.

sebenzisa
Iimveliso zokhathalelo lobuqu: Sisithako esiphambili kwiimveliso zokucoca ezinje ngeeshampu, iijeli zeshawa, kunye nezicoci zezandla, ezinoxanduva lokuvelisa i-lather etyebileyo nexineneyo kumava amnandi okusebenzisa, ngelixa isusa ngamandla ioyile kunye nokungcola eluswini nasezinweleni. , ishiya abasebenzisi beziva behlaziyekile kwaye becocekile.
Abacoci bamakhaya: Kwiimveliso zokucoca ezindlini ezifana nesepha yesitya kunye nesepha yokuhlamba impahla, amandla okucoca aphezulu e-SLES kunye nokunyibilika kakuhle kwamanzi kunceda ukususa ngokufanelekileyo amabala anenkani ezityeni nasezimpahleni, kunye neempawu zayo ezinogwebu zinokunceda abasebenzisi ukuba bagwebe ubungakanani bococeko.
Ukucocwa kwemizi-mveliso: Kwezinye iimeko zoshishino, ezifana nokucoca isinyithi kunye nokucoca imoto, inceda kwakhona ukususa ukungcola okufana neoli kunye nothuli kunye nokuphucula ukusebenza kakuhle kokucoca kunye nomgangatho kunye nobuchule obubalaseleyo bokuchithwa kunye ne-emulsification.
