【Kev Ua Tau Zoo】2,4,7,9-Tetramethyl-5-decyne-4,7-diol Cov khoom surfactant yog ib qho khoom siv ntau yam uas muaj cov yam ntxwv ntawm kev ntub dej, tshem cov npuas dej thiab kev tawg. Cov khoom no yog ib qho symmetrical non-ionic surfactant. Nws cov qauv tshuaj gemini tshwj xeeb ua rau cov khoom no txo qhov nro ntawm qhov chaw, tswj cov npuas dej, thiab txo qhov rhiab heev ntawm dej. Nws tuaj yeem siv rau hauv ntau yam lag luam: xws li cov txheej txheem kev lag luam uas siv dej, xim ntoo uas siv dej, xim yas uas siv dej, kua mem uas siv dej, OPV, cov nplaum uas rhiab heev rau siab, kev tsim cov xim thiab cov xim zas, kev lag luam ua hlau, flux, tshuaj tua kab, thiab lwm yam.
Nws txav mus sai sai, txo qhov nro ntawm qhov chaw dynamic thiab qhov nro ntawm qhov chaw static, defoams thiab inhibits foams, muaj qhov tsis tshua muaj dej rhiab heev, tuaj yeem ntub ntau yam substrates, tsis tsim micelles, muaj kev ruaj khov thermal zoo, thiab muaj kev ruaj khov acid-base zoo. Cov dej-raws li ntub dej muaj qhov nro ntawm qhov chaw siab dua li cov tshuaj yaj thiab xav tau ntxiv surfactants los txhim kho kev ntub dej. Txawm li cas los xij, cov neeg sawv cev ntub dej ib txwm yuav ua rau ua npuas dej thiab stabilizing ua npuas dej. Yog tias ntxiv defoamers, cov teeb meem ntub dej tsis zoo xws li pinholes yuav rov tshwm sim.
Nws tuaj yeem zam tau cov teeb meem no. Kev ua tau zoo dua li cov tshuaj surfactants ib txwm muaj, thiab nws tuaj yeem muab qhov nro ntawm qhov chaw qis heev thiab kev ua npuas ncauj tsis pub dhau nyob rau hauv cov xwm txheej dynamic.
Vim nws cov qauv molecular tshwj xeeb, defoaming cov khoom series surfactants yog ib tug zoo symmetrical non-ionic defoaming neeg sawv cev.
Cov surfactant no tsis muaj qhov chaw huab thiab muaj peev xwm ua kom cov npuas dej tsis lo rau ntev hauv ntau qhov kub thiab txias. Kev rhiab dej Ntau cov surfactants ua rau muaj teeb meem rhiab dej ntawm qhov chaw coated tom qab ziab.
Cov surfactants uas muaj dej ntau xws li anionic (dioctyl sulfosuccinate sodium ntsev) lossis polyethoxylated surfactants yooj yim yaj dua hauv dej, ua rau muaj qhov tsis zoo ntawm cov txheej qhuav, xws li nplaum, plaub hau dawb, pos huab, thiab tsis tiv taus dej.
Nws raug pom zoo kom ntxiv cov emulsion lossis resin thiab lwm yam surfactants ua ntej, tom qab ntawd ntxiv 2,4,7,9-Tetramethyl-5-decyne-4,7-diol series surfactants. Qhov no ua kom muaj kev sib kis ntau tshaj plaws rau hauv lub cev, xav tau kev sib kis kom huv si rau 15-30 feeb. Qee cov 2,4,7,9-Tetramethyl-5-decyne-4,7-diol series surfactants yuav crystallize thaum lub sijhawm thauj mus los lossis khaws cia ntawm qhov kub qis heev; cua sov maj mam thaum lub sijhawm sib kis me ntsis tuaj yeem kho lawv zoo.
Qib Ntxiv Pom Zoo USE:
Txheej dej: 0.1% - 3.0%
Cov nplaum uas muaj dej siab: 0.1%—1.0%
Cov kua dej: 0.1% -1.0%
Cov kua mem dav hlau: 0.1% -1.0%
Cov ntaub ntawv saum toj no yog qhov ntau npaum li cas, thiab qhov ntau npaum li cas zoo tshaj plaws yog txiav txim siab los ntawm ntau qhov kev sim
Cov txiaj ntsig:
Nthuav sai sai, txo qhov kev nruj ntawm qhov chaw dynamic thiab static, defoaming, thiab antifoaming, tsis tshua muaj kev rhiab heev rau dej, ntub ntau yam substrates yam tsis tsim micelles. zoo thermal stability thiab acid-alkali tsis kam.
Kev ntub dej:
Cov txheej txheem ua los ntawm dej muaj qhov nro ntawm qhov chaw siab dua li cov txheej txheem ua kom yaj, thiab nws yog qhov tsim nyog los ntxiv cov tshuaj surfactant kom txhim kho qhov ntub dej. Cov neeg sawv cev ntub dej ib txwm muaj feem ua rau muaj teeb meem ua npuas dej thiab kev ruaj khov. Cov khoom lag luam no tuaj yeem kov yeej cov teeb meem no, muab kev ua tau zoo tshaj plaws hauv kev muab qhov nro ntawm qhov chaw qis thiab tshem tawm cov npuas dej txawm tias nyob rau hauv cov xwm txheej dynamic.
Kev ua npuas dej:
Cov tshuaj surfactants no, nrog lawv cov qauv molecular tshwj xeeb, ua haujlwm zoo heev rau cov tshuaj defoaming uas tsis yog ionic. Lawv ua rau muaj cov khoom defoaming ruaj khov thoob plaws ntau qhov kub thiab txias yam tsis muaj qhov chaw clouding.
Kev rhiab heev ntawm dej:
Muaj ntau yam surfactants ua rau muaj teeb meem tsis haum dej ntawm qhov chaw qhuav. Cov surfactants uas muaj dej ntau xws li anionic (dioctyl sulfosuccinate) lossis polyethoxylate surfactants yooj yim yaj hauv dej, ua rau muaj qhov tsis zoo ntawm qhov chaw hauv cov txheej qhuav xws li nplaum thiab ua kom dawb, ua kom atomization, thiab tsis tiv taus dej.
