Surfactants yog ib chav kawm ntawm cov tshuaj siv dav siv hauv lub neej txhua hnub thiab kev tsim khoom lag luam.

Lawv muaj cov yam ntxwv ntawm kev txo cov kua deg nro thiab txhim kho kev sib cuam tshuam muaj peev xwm ntawm cov kua thiab khoom lossis roj.

TMAO, Trimethylamine oxide, dihydrate, CAS NO.: 62637-93-8, yog tus neeg sawv cev ua haujlwm saum npoo av thiab surfactants, tuaj yeem siv rau kev ntxuav.

TMAO tsis muaj zog oxidants

Trimethylamine oxide, raws li ib tug tsis muaj zog oxidant, yog siv nyob rau hauv cov tshuaj tiv thaiv rau lub synthesis ntawm aldehydes, oxidation ntawm organic boranes, thiab tso tawm ntawm organic ligands los ntawm hlau carbonyl tebchaw.

•  Cov qauv ntawm surfactants

Surfactants tau muab faib ua ob ntu: pawg hydrophilic thiab pawg hydrophobic.Ib pawg hydrophilic yog ib pawg polar uas muaj cov atoms xws li oxygen, nitrogen, lossis sulfur uas yog hydrophilic.Cov pab pawg hydrophobic yog qhov chaw hydrophobic, feem ntau yog tsim los ntawm cov pab pawg tsis muaj polar xws li cov saw ntev alkyl lossis cov tshuaj tsw qab.Cov qauv no tso cai rau cov surfactants cuam tshuam nrog dej thiab hydrophobic tshuaj xws li roj.

•  Lub mechanism ntawm kev txiav txim ntawm surfactants

Surfactants tsim ib txheej molecular ntawm cov kua dej, hu ua txheej adsorption.Kev tsim cov txheej txheem adsorption yog vim qhov tsim ntawm hydrogen bonds ntawm hydrophilic pawg ntawm surfactant molecules thiab dej molecules, thaum cov hydrophobic pawg cuam tshuam nrog huab cua lossis roj molecules.Cov txheej txheem adsorption no tuaj yeem txo qhov nro ntawm cov kua, ua kom yooj yim rau cov kua kom ntub cov khoom nto.

Surfactants tuaj yeem tsim cov qauv micelle.Thaum cov concentration ntawm surfactant tshaj qhov tseem ceeb micelle concentration, surfactant molecules yuav nws tus kheej sib sau ua micelles.Micelles yog cov qauv me me uas tsim los ntawm cov pab pawg hydrophilic ntsib cov theem aqueous thiab cov pab pawg hydrophobic ntsib sab hauv.Micelles tuaj yeem encapsulate hydrophobic tshuaj xws li roj thiab disperse lawv nyob rau hauv lub aqueous theem, thiaj li ua tiav emulsifying, dispersing, thiab dissolving teebmeem.

• Daim ntawv thov teb ntawm surfactants

1. Tus neeg saib xyuas tu: Surfactants yog cov khoom tseem ceeb ntawm cov tshuaj ntxuav, uas tuaj yeem txo qhov nro ntawm cov dej, ua kom yooj yim rau cov dej ntub thiab nkag mus, yog li txhim kho cov nyhuv tu.Piv txwv li, cov tshuaj ntxuav xws li ntxhua khaub ncaws ntxhua khaub ncaws thiab ntxhua khaub ncaws ntxhua khaub ncaws muaj surfactants.

2. Cov khoom siv tu tus kheej: Surfactants tuaj yeem ua rau cov khoom tu tus kheej xws li tshuaj zawv plaub hau thiab da dej gel tsim cov npuas dej nplua nuj, muab kev ntxuav zoo thiab ntxuav kom huv.

3. Tshuaj pleev ib ce: Surfactants ua lub luag haujlwm hauv emulsifying, dispersing, thiab stabilizing tshuaj pleev ib ce.Piv txwv li, emulsifiers thiab dispersants nyob rau hauv cov tshuaj pleev ib ce, lub ntsej muag cream thiab tshuaj pleev ib ce yog surfactants.

4. Tshuaj tua kab thiab ua liaj ua teb additives: Surfactants tuaj yeem txhim kho qhov ntub dej thiab permeability ntawm cov tshuaj tua kab, txhim kho lawv cov adsorption thiab permeation cuam tshuam, thiab txhim khu kev ua tau zoo ntawm cov tshuaj tua kab.

5. Kev lag luam roj av thiab tshuaj lom neeg: Surfactants ua lub luag haujlwm tseem ceeb hauv cov txheej txheem xws li kev tshem tawm roj, kev txhaj tshuaj hauv dej, thiab roj-dej sib cais.Tsis tas li ntawd, surfactants yog dav siv nyob rau hauv lubricants, xeb inhibitors, emulsifiers, thiab lwm yam teb.

Cov ntsiab lus:

Surfactants yog ib hom tshuaj lom neeg uas muaj peev xwm txo tau cov kua deg nro thiab txhim khu kev sib cuam tshuam ntawm cov kua thiab khoom lossis roj.Nws cov qauv yog tsim los ntawm hydrophilic thiab hydrophobic pawg, uas tuaj yeem tsim cov txheej txheem adsorption thiab cov qauv micelle.Surfactants tau dav siv hauv kev tu cov neeg ua haujlwm, cov khoom tu tus kheej, tshuaj pleev ib ce, tshuaj tua kab thiab kev ua liaj ua teb additives, roj av thiab tshuaj industries, thiab lwm yam.Los ntawm kev nkag siab txog cov ntsiab lus tshuaj ntawm surfactants, peb tuaj yeem nkag siab zoo dua lawv cov kev siv thiab cov txheej txheem ntawm kev ua haujlwm hauv ntau qhov chaw.
