Alkyl polyglucoside (APG) yog dab tsi?

Alkyl polyglycosides yog hemiacetal hydroxyl pawg ntawm cov piam thaj thiab fatty cawv hydroxyl pawg, uas tau los ntawm kev poob ib molecule ntawm dej nyob rau hauv lub catalysis ntawm acid. Nws yog ib pawg ntawm nonionic surfactant, nws tau dav siv nyob rau hauv ntau yam tshuaj niaj hnub, tshuaj pleev ib ce, tshuaj ntxuav tes thiab kev lag luam. Cov ntaub ntawv raw yog tsuas yog muab rho tawm los ntawm xibtes thiab txiv maj phaub roj yog li nws raug suav tias yog eco-phooj ywg vim lawv ua tiav biodegradation, cov cuab yeej no ua rau yuav luag tsis muaj lwm yam surfactant piv rau nws. Yog li APG tau siv dav hauv ntau yam ntaub ntawv.

2.Qhov kev ua tau zoo ntawm APG siv los txhim kho cov roj hnyav rov qab.
Alkyl polyglucosides (APG) yog ib qho ntsuab surfactant nrog zoo interfacial kev ua si, emulsification, foaming thiab wettability, thiab muaj peev xwm los txhim kho cov roj hnyav rov qab nyob rau hauv kub thiab salinity siab. Qhov kev sib tw nto, qhov nro ntawm lub ntsej muag, cov cuab yeej emulsion, emulsion stability thiab emulsion droplet loj ntawm APG tau kawm. Tsis tas li ntawd qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov kev ua haujlwm ntawm lub ntsej muag thiab cov khoom emulsifying ntawm APG tau kawm. Cov txiaj ntsig tau pom tias APG muaj kev cuam tshuam zoo hauv kev ua haujlwm thiab emulsifying zog ntawm txhua tus surfactants. Tsis tas li ntawd, kev ua haujlwm ntawm interfacial thiab emulsifying kev ua tau zoo ntawm APG yog qhov ruaj khov, thiab txawm tias zoo dua nrog qhov nce ntawm qhov kub thiab txias, thaum qhov kev ua haujlwm ntawm lub ntsej muag thiab emulsifying kev ua tau zoo ntawm lwm cov surfactants tau zuj zus mus rau qhov sib txawv. Piv txwv li, ntawm 90 ℃ nrog salinity ntawm 30 g / L, cov roj rov qab los ntawm kev siv APG tuaj yeem ncav cuag li 10.1%, ze li ob zaug siab dua li qhov qub EOR surfactant. Cov txiaj ntsig tau pom tias APG yog ib qho zoo surfactant rau kev txhim kho cov roj hnyav rov qab ntawm qhov kub thiab txias siab.

3. Cov khoom ntawm Alkyl polyglucoside (APG)
Cov yam ntxwv ua haujlwm ntawm Alkyl Polyglucoside (APG) surfactant, xws li foaming, emulsification thiab bio-degradability.
Ua npuas ncauj: Alkyl polyglucoside surfactants tsis muaj tshuaj lom, tsis ua rau khaus, zoo sib xws thiab muaj foaming zoo thiab ua haujlwm saum npoo. Lawv tau siv dav hauv cov tshuaj ntxuav tes thiab cov khoom tu tus kheej los txhawb kev tsim ua npuas ncauj.
