Sodium Laureth Sulfate CAS 3088-31-1
Sodium Laureth Sulfate CAS 3088-31-1 Cov Ntaub Ntawv
Lub cev
Cov tsos mob: Cov sodium laureth sulfate yog cov kua tsis muaj xim lossis lub teeb daj daj, qhov kev ntxhib los mos no tshwm sim los ntawm kev sib cuam tshuam hauv nruab nrab, xws li hydrogen bonding, uas kuj txiav txim siab tias nws yuav tsum tau yoog rau cov khoom tshwj xeeb hauv kev ntim khoom thiab kev thauj mus los los tiv thaiv cov khoom seem thiab txhaws. .
Solubility: Nws muaj cov dej solubility zoo heev, ua tsaug rau cov saw hlau polyether thiab sulfonic acid pawg hauv cov qauv molecular, uas tuaj yeem ua ionized sai hauv dej los tsim cov anion ruaj khov, uas ua rau tag nrho cov molecule yooj yim dispersed nyob rau hauv dej los ua kom pom tseeb thiab pob tshab kua, uas yog yooj yim rau daim ntawv thov nyob rau hauv ntau yam dej-raws li formula systems.
Melting point thiab ntom: Vim nws yog kua, nws yog ib qho tseem ceeb me me los tham txog melting point; Nws qhov ceev yog feem ntau me ntsis siab dua li cov dej, nruab nrab ntawm 1.05 thiab 1.08 g / cm³, thiab cov ntaub ntawv ceev pab kom raug xam qhov ntim thiab loj hloov pauv thaum lub sij hawm tsim thiab noj.
Cov khoom siv tshuaj
Surfactant: Raws li muaj zog surfactant, nws txo qhov nro ntawm dej. Thaum ntxiv rau dej, cov molecules yuav spontaneously tsiv mus rau huab cua-dej interface, nrog rau qhov kawg hydrophobic ncav cuag huab cua thiab lub hydrophilic kawg nyob rau hauv dej, cuam tshuam lub keeb kwm nruj kev npaj ntawm dej molecules, ua kom yooj yim rau cov dej sib kis. thiab ntub dej ntawm cov khoom siv, yog li txhim kho lub peev xwm los ntxuav, emulsify, ua npuas ncauj, thiab lwm yam.
Kev ruaj ntseg: Nws tuaj yeem tswj xyuas cov tshuaj lom neeg zoo hauv ntau qhov pH (feem ntau pH 4 - 10), uas ua rau nws tsim nyog rau ntau yam khoom tsim nyob rau hauv qhov sib txawv acid-alkali ib puag ncig, tab sis nyob rau hauv lub sij hawm ntev ntawm cov kua qaub thiab alkalis. , hydrolysis thiab decomposition kuj tshwm sim, cuam tshuam kev ua haujlwm.
Kev sib cuam tshuam nrog lwm yam tshuaj: thaum nws ntsib cationic surfactants, nws yuav tsim ib qho precipitate vim tsub nqi attraction thiab poob nws cov dej num; Txawm li cas los xij, thaum ua ke nrog lwm cov anionic thiab nonionic surfactants, nws muaj peev xwm feem ntau sib koom ua ke los txhim kho kev tu thiab ua npuas dej ntawm cov qauv.
Txoj kev npaj:
Feem ntau, lauryl cawv yog siv los ua cov khoom pib, thiab cov tshuaj tiv thaiv ethoxylation yog ua ntej, thiab sib txawv ntawm cov ethylene oxide units tau qhia kom tau txais laureth. Tom qab ntawd, tom qab sulfonation thiab neutralization cov kauj ruam, laureth polyester yog kho nrog sulfonating agents xws li sulfur trioxide, thiab ces neutralized los ntawm kev ntxiv sodium hydroxide thaum kawg npaj sodium laureth sulfate. Tag nrho cov txheej txheem yog nruj me ntsis tswj los ntawm cov tshuaj tiv thaiv kub, siab thiab cov khoom sib piv, thiab cov khoom zoo yuav raug cuam tshuam yog tias muaj qhov sib txawv me ntsis hauv lub pas dej.
siv
Cov khoom siv kho mob: nws yog cov tshuaj ntxuav kom huv thiab ntxuav tes, thiab siv tshuaj ntxuav tes rau lub cev, thiab siv tshuaj ntxuav tes kom huv si rau cov roj thiab cov plaub hau , ua rau cov neeg siv xav tias refreshed thiab huv si.
Cov cuab yeej siv hauv tsev: Hauv cov khoom siv tu tsev xws li tshuaj ntxuav tais diav thiab ntxhua khaub ncaws, SLES lub zog ntxuav siab thiab dej solubility zoo pab tshem tawm cov tawv nqaij ntawm cov tais diav thiab khaub ncaws, thiab nws cov khoom ua npuas kuj tuaj yeem pab cov neeg siv txiav txim siab txog kev huv.
Kev tu vaj tse: Hauv qee qhov kev lag luam, xws li kev tu hlau thiab tu tsheb, nws kuj tseem pab tshem tawm cov impurities xws li roj thiab plua plav thiab txhim kho kev tu kom zoo thiab ua haujlwm zoo nrog nws qhov zoo tshaj plaws decontamination thiab emulsification peev xwm.
