Kev ua haujlwm ntawm qhov chaw thiab kev tiv thaiv dej tawv ntawm AES70
Aliphatic cawv polyoxyethylene ether sodium sulfate (AES) yog ib qho gel nplaum dawb lossis daj daj, yooj yim yaj hauv dej. Nws muaj cov yam ntxwv zoo heev rau kev tshem tawm cov pa phem, emulsification thiab ua npuas dej. Yooj yim rau biodegradation, biodegradation degree ntau dua 90%. Siv dav hauv tshuaj zawv plaub hau, kua da dej, tshuaj ntxuav tais diav, xab npum sib xyaw thiab lwm yam tshuaj ntxuav tes; Siv rau hauv kev lag luam textile, tus neeg sawv cev ntub dej, tus neeg sawv cev ntxuav, thiab lwm yam. Anionic surfactant.
Txog qhov ua haujlwm ntawm qhov chaw thiab dej tsis kam ntawm cov cawv rog polyoxyethylene ether sodium sulfate (AES):
1. Kev ua haujlwm ntawm AES:
AES muaj zog ua kom ntub, ua kom emulsifying thiab ntxuav tau zoo. Nws qhov kev nruj ntawm qhov chaw qis thiab nws qhov kev sib xyaw tseem ceeb me me.
Cov ntaub ntawv qhia tau hais tias qhov kev nruj ntawm qhov chaw thiab lub zog ntub dej raug cuam tshuam los ntawm qhov ntev ntawm cov saw hlau carbon ntawm cov ethylene oxide sib txuas. Qhov kev nruj ntawm qhov chaw thiab lub zog ntawm ethylene oxide nce nrog rau qhov nce ntawm tus lej mole ntxiv. Tsis tas li ntawd, thaum qhov concentration ntawm cov kua nce ntxiv, qhov kev nruj ntawm qhov chaw txo qis, tab sis thaum mus txog cov kua nplaum tseem ceeb, qhov kev nruj ntawm qhov chaw yuav tsis txo qis dua txawm tias qhov concentration nce ntxiv. Qhov kev ntub dej ntawm ethylene oxide nce ntxiv thaum tus lej ntawm cov molecule ntxiv nce ntxiv, thiab txo qis thaum tus lej ntawm cov molecule ntxiv nce ntxiv.
2. AES tawv dej tsis kam:
AES muaj kev tiv thaiv zoo heev rau cov dej tawv, thiab nws qhov sib xws nrog cov dej tawv yog qhov zoo heev. Qhov ntsuas kev ruaj khov ntawm cov calcium thiab magnesium ions yog siab heev, thiab cov calcium xab npum dispersion zoo heev.
Raws li cov ntaub ntawv tshaj tawm: cov saw hlau carbon C12-14 cawv AES hauv 6300ppm dej hiav txwv, nws (dej hiav txwv) calcium nws dispersion ntawm 8%. Hauv 330ppm dej tawv, nws cov calcium dispersion yog 4%. Calcium ion stability index> 10000ppmCaCO3. AES calcium ion stability index siab heev, vim nws cov molecules muaj kev kam rau calcium (magnesium) ions zoo, uas yog, nws tuaj yeem tsim cov organic calcium (magnesium) ntsev nrog calcium (magnesium) ions, thiab cov calcium (magnesium) ntsev uas lawv tsim tau yooj yim los sib xyaw nrog cov pab pawg hydrophilic thiab teb los tsim cov calcium (magnesium) ntsev sib xyaw uas yooj yim yaj. Yog li ntawd, qhov solubility hauv dej ntawm AES zoo heev, thiab tuaj yeem siv rau kev ntxuav kub qis. Kev sim qhia tau tias qhov solubility hauv dej ntawm C1-14 cawv AES zoo dua li ntawm C14-1 cawv lossis 16-18 cawv AES. Qhov solubility ntawm AES hauv dej nce nrog rau qhov nce ntawm molar tus lej ntawm condensed ethylene oxide.
