Aliphatic cawv polyoxyethylene ether sodium sulfate (AES) yog xim dawb lossis lub teeb daj gel muab tshuaj, yooj yim soluble hauv dej.Nws muaj zoo heev decontamination, emulsification thiab foaming zog.Yooj yim rau biodegrade, biodegradation degree yog ntau dua 90%.Siv dav hauv tshuaj zawv plaub hau, dej da dej, tshuaj ntxuav tais diav, xab npum sib xyaw thiab lwm yam tshuaj pleev ib ce;Siv hauv kev lag luam textile wetting tus neeg saib xyuas, tu tus neeg saib xyuas, thiab lwm yam. Anionic surfactant.
Txog kev ua haujlwm saum npoo av thiab dej tsis kam ntawm cov dej cawv fatty cawv polyoxyethylene ether sodium sulfate (AES):
1. Cov dej num ntawm AES:
AES muaj zog ntub dej, emulsifying thiab ntxuav lub zog.Nws qhov nro saum npoo yog tsawg thiab nws qhov tseem ceeb concentration yog me me.
Cov ntaub ntawv qhia tau hais tias qhov nro ntawm qhov chaw thiab lub zog ntub dej yog cuam tshuam los ntawm qhov ntev ntawm cov saw hlau ntawm cov khoom sib txuas ethylene oxide.Qhov nro thiab quab yuam ntawm ethylene oxide nce nrog qhov nce ntawm qhov sib ntxiv mole tooj.Tsis tas li ntawd, raws li cov concentration ntawm cov kua nce, qhov nro ntawm qhov chaw txo, tab sis thaum cov kua nplaum tseem ceeb tau mus txog, qhov nro saum npoo yuav tsis txo qis dua txawm tias qhov concentration nce.Lub wettability ntawm ethylene oxide nce thaum tus naj npawb ntawm cov molecules ntxiv nce, thiab txo qis thaum tus naj npawb ntawm cov molecules ntxiv nce.
2. AES nyuaj dej tsis kam:
AES muaj kev tiv thaiv zoo heev rau cov dej tawv, thiab nws txoj kev sib raug zoo nrog cov dej tawv yog qhov zoo heev.Lub stability Performance index ntawm calcium thiab magnesium ions yog siab heev, thiab dispersion ntawm calcium xab npum yog zoo heev.
Raws li cov ntaub ntawv qhia: carbon saw C12-14 cawv AES nyob rau hauv 6300ppm seawater, nws (seawater) calcium nws dispersion ntawm 8%.Hauv 330ppm dej nyuaj, nws cov calcium dispersion yog 4%.Calcium ion stability index> 10000ppmCaCO3.AES calcium ion stability Performance index yog siab heev, vim hais tias nws cov molecules muaj siab kam rau calcium (magnesium) ions, uas yog, nws muaj peev xwm tsim organic calcium (magnesium) ntsev nrog calcium (magnesium) ions, thiab calcium (magnesium) ntsev lawv tsim. yog ib qho yooj yim los ua ke nrog cov pab pawg hydrophilic thiab hnov mob los tsim cov calcium (magnesium) ntsev sib txuas uas yooj yim yaj.Yog li ntawd, cov dej solubility ntawm AES yog qhov zoo heev, thiab tuaj yeem siv rau kev ntxhua khaub ncaws qis.Cov kev ntsuam xyuas qhia tau hais tias cov dej solubility ntawm C1-14 cawv AES yog superior rau C14-1 cawv los yog 16-18 cawv AES.Lub solubility ntawm AES hauv dej nce nrog qhov nce ntawm molar tooj ntawm condensed ethylene oxide.
