Sodium Laureth Sulfate CAS 3088-31-1

Sodium Laureth Sulfate CAS 3088-31-1 Zambiri

Zakuthupi
Maonekedwe: Wamba wa sodium laureth sulfate ndi madzi opanda mtundu kapena opepuka achikasu a viscous, mawonekedwe owoneka bwinowa amachokera kuzinthu zama intermolecular, monga hydrogen bonding, zomwe zimatsimikiziranso kuti ziyenera kusinthidwa kuti zigwirizane ndi zida zenizeni pakupakira ndi zoyendera kuti zipewe zotsalira ndi kutsekeka. .
Kusungunuka: Ili ndi kusungunuka kwamadzi bwino kwambiri, chifukwa cha gawo la polyether chain ndi gulu la sulfonic acid mu dongosolo la maselo, lomwe limatha kukhala ionized m'madzi kuti likhale lokhazikika, lomwe limapangitsa kuti molekyulu yonse ikhale yomwazikana m'madzi kuti ikhale yomveka komanso transparent solution, yomwe ndiyosavuta kugwiritsa ntchito pamakina osiyanasiyana otengera madzi.
Malo osungunuka ndi kachulukidwe: Popeza ndi madzi, sikuli kofunikira kwenikweni kunena za malo osungunuka; Kachulukidwe ake nthawi zambiri amakhala okwera pang'ono kuposa madzi, pakati pa 1.05 ndi 1.08 g/cm³, ndipo deta ya kachulukidwe imathandiza kuwerengera molondola kuchuluka kwa voliyumu ndi kutembenuka kwa misa panthawi yopanga ndi dosing.

Mankhwala katundu
Surfactant: Monga surfactant yamphamvu, imachepetsa kwambiri kuthamanga kwa madzi. Mukawonjezeredwa kumadzi, mamolekyuwa amasamukira kumadzi am'mlengalenga, ndipo mathero a hydrophobic amafikira mlengalenga ndipo mathero a hydrophilic otsalira m'madzi, kusokoneza dongosolo lolimba la mamolekyu amadzi, zomwe zimapangitsa kuti madzi afalikire mosavuta. ndi kunyowa pamalo olimba, potero kumakulitsa luso loyeretsa, emulsify, thovu, etc.
Kukhazikika: Kutha kukhalabe kukhazikika kwamankhwala mumitundu yonse ya pH (nthawi zambiri pH 4 - 10), yomwe imapangitsa kuti ikhale yoyenera kupangira zinthu zosiyanasiyana m'malo osiyanasiyana acid-alkali, koma pakapita nthawi yayitali ma acid amphamvu ndi alkalis. , hydrolysis ndi kuwonongeka zingathenso kuchitika, zomwe zimakhudza ntchito.
Kuyanjana ndi zinthu zina: ikakumana ndi ma cationic surfactants, ipanga mpweya chifukwa chokopa kukopa ndikutaya ntchito yake pamwamba; Komabe, zikaphatikizidwa ndi ma anionic ndi ma nonionic surfactants, nthawi zambiri zimatha kugwirizanitsa kuti zipititse patsogolo kuyeretsa ndi kuchita thovu pamapangidwewo.

Njira yokonzekera:
Nthawi zambiri, mowa wa lauryl umagwiritsidwa ntchito ngati poyambira, ndipo ethoxylation reaction imachitika koyamba, ndipo mayunitsi osiyanasiyana a ethylene oxide amayambitsidwa kuti apeze laureth. Kenako, pambuyo sulfonation ndi neutralization masitepe, laureth poliyesitala mankhwala ndi sulfonating wothandizira monga sulfure trioxide, ndiyeno neutralized ndi kuwonjezera sodium hydroxide potsiriza kukonzekera sodium laureth sulphate. Njira yonseyi imayendetsedwa mosamalitsa ndi kutentha, kuthamanga ndi chiŵerengero cha zinthu, ndipo khalidwe la mankhwala lidzakhudzidwa ngati pali kusiyana pang'ono mu dziwe.

ntchito
Zopangira zodzisamalira: Ndiwofunika kwambiri pakutsuka zinthu monga ma shampoos, ma gels osambira, ndi zotsukira m'manja, zomwe zimakhala ndi udindo wopanga chimbudzi cholemera komanso chowundana kuti chizigwiritsidwa ntchito mosangalatsa, ndikuchotsa mwamphamvu mafuta ndi litsiro pakhungu ndi tsitsi. , kusiya ogwiritsa ntchito akumva otsitsimula komanso aukhondo.
Zotsukira m'nyumba: M'zinthu zotsukira m'nyumba monga sopo wa mbale ndi zotsukira zovala, mphamvu yotsuka kwambiri ya SLES ndi kusungunuka kwamadzi bwino kumathandiza kuchotsa madontho owuma pa mbale ndi zovala, komanso kutulutsa thovu kungathandizenso ogwiritsa ntchito kuweruza kuchuluka kwa ukhondo.
Kuyeretsa mafakitale: M'mafakitale ena, monga kuyeretsa zitsulo ndi kuyeretsa magalimoto, kumathandizanso kuchotsa zonyansa monga mafuta ndi fumbi komanso kukonza bwino kuyeretsa ndi khalidwe lake ndi mphamvu zake zowononga ndi emulsification.
