Sodium Laureth Sulfate CAS 3088-31-1 Boitsebiso
Ea nama
Ponahalo: Sodium laureth sulfate e tloaelehileng ke mokelikeli o mosehla o mosehla o se nang 'mala kapa o mosehla o mosehla, sebopeho sena sa viscous se bakoa ke ho sebelisana ha limolek'hule, joalo ka hydrogen bonding, e leng se etsang qeto ea hore e hloka ho ikamahanya le lisebelisoa tse khethehileng tsa ho paka le lipalangoang ho thibela masala le ho koala. .
Solubility: E na le ho qhibiliha ha metsi ka mokhoa o babatsehang, ka lebaka la karolo ea polyether chain le sehlopha sa sulfonic acid mohahong oa limolek'hule, e ka khonang ho ionized ka potlako metsing ho etsa anion e tsitsitseng, e leng se etsang hore molek'hule kaofela e hasane habonolo ka metsing ho theha lehlaka le hlakileng. tharollo e pepeneneng, e loketseng ho sebelisoa lits'ebetsong tse fapaneng tse thehiloeng ho metsi.
melting point and density: Kaha ke mokelikeli, ha ho bohlokoa hakaalo ho bua ka ntlha ea ho qhibiliha; Boima ba eona hangata bo phahame hanyane ho feta ba metsi, pakeng tsa 1.05 le 1.08 g/cm³, 'me data ea density e thusa ho bala ka nepo molumo le phetoho ea bongata nakong ea ho etsoa le ho noa.
Lintho tsa lik'hemik'hale
Surfactant: Joalo ka sehatsetsi se matla, se fokotsa tsitsipano ea metsi haholo. Ha li eketsoa metsing, limolek'hule li tla fallela sebakeng sa metsi a moea, 'me pheletso ea hydrophobic e fihle moeeng le pheletso ea hydrophilic e setseng ka metsing, e sitise tlhophiso ea pele ea limolek'hule tsa metsi, e etsa hore ho be bonolo hore metsi a hasane. le ho koloba holim'a libaka tse tiileng, ka hona ho matlafatsa bokhoni ba ho hloekisa, ho emulsify, foam, joalo-joalo.
Botsitso: E ka boloka botsitso bo botle ba lik'hemik'hale ka mefuta e mengata ea pH (hangata pH 4 - 10), e etsang hore e tšoanelehe bakeng sa mefuta e fapaneng ea lihlahisoa tsa lihlahisoa libakeng tse fapaneng tsa acid-alkali, empa tlas'a ketso ea nako e telele ea li-acid tse matla le alkalis. , hydrolysis le ho bola ho ka boela ha etsahala, ho ama ts'ebetso.
Tšebelisano le lintho tse ling: ha e kopana le li-surfactants tsa cationic, e tla theha pula ka lebaka la ho khahloa ke tefiso le ho lahleheloa ke mosebetsi oa eona oa holim'a metsi; Leha ho le joalo, ha e kopantsoe le li-surfactants tse ling tsa anionic le tsa nonionic, hangata e ka kopana ho ntlafatsa ts'ebetso ea ho hloekisa le ho foamma ea sebopeho.
Mokhoa oa ho itokisa:
Ka kakaretso, joala ea lauryl e sebelisoa e le thepa ea ho qala, 'me karabelo ea ethoxylation e etsoa pele,' me palo e fapaneng ea likarolo tsa ethylene oxide e hlahisoa ho fumana laureth. Ka mor'a moo, ka mor'a mehato ea sulfonation le neutralization, polyester ea laureth e phekoloa ka mahlahana a sulfonating a kang sulfur trioxide, ebe e fokotsoa ka ho eketsa sodium hydroxide ho qetela ho lokisa sodium laureth sulfate. Tshebetso eohle e laoloa ka thata ke mocheso oa karabelo, khatello le karo-karolelano ea lintho tse bonahalang, 'me boleng ba sehlahisoa bo tla ameha haeba ho na le phapang e fokolang ka letamo.
tshebediso
Lihlahisoa tsa tlhokomelo ea motho ka mong: Ke motsoako oa bohlokoa oa ho hloekisa lihlahisoa tse kang li-shampoo, li-gels tsa ho hlapa le li-sanitizer tsa letsoho, tse ikarabellang bakeng sa ho hlahisa lesela le nonneng le le teteaneng bakeng sa boiphihlelo bo monate ba ts'ebeliso, ha li ntse li tlosa oli le litšila letlalong le moriring. , e siea basebelisi ba ikutloa ba khatholohile ba bile ba hloekile.
Lisebelisoa tsa ho hloekisa ka tlung: Ka lihlahisoa tsa ho hloekisa ka tlung tse kang sesepa sa lijana le sesepa sa ho hlatsoetsa, matla a phahameng a ho hloekisa a SLES le ho qhibiliha ha metsi hantle ho thusa ho tlosa matheba a manganga lijana le liaparo, 'me thepa ea eona e phophomang e ka boela ea thusa basebelisi ho ahlola tekanyo ea bohloeki.
Ho hloekisa indasteri: Maemong a mang a indasteri, joalo ka ho hloekisa tšepe le ho hloekisa koloi, ho boetse ho thusa ho tlosa litšila tse kang oli le lerōle le ho ntlafatsa ts'ebetso ea ho hloekisa le boleng ka bokhoni ba eona bo ikhethang ba ho hloekisa le ho emulsification.
