【Kev ua tau zoo】2,4,7,9-Tetramethyl-5-decyne-4,7-diol Cov khoom lag luam surfactant yog cov khoom siv ntau yam ntxiv nrog cov dej ntub, de-foaming thiab dispersing zog. Cov khoom yog symmetrical non-ionic surfactant. Nws cov qauv tshuaj gemini tshwj xeeb ua rau cov khoom siv los txo qhov nro, tswj ua npuas dej, thiab txo cov dej rhiab heev. Nws tuaj yeem siv rau hauv ntau qhov kev lag luam: xws li dej-raws li kev lag luam coatings, dej-raws li ntoo xim, dej-raws li yas xim, dej-raws li number case, OPV, siab-rhiab nplaum nplaum, pigment thiab dye manufacturing, hlau ua kev lag luam, flux , tshuaj tua kab, thiab lwm yam.
Nws migrate sai, txo dynamic nto nro thiab zoo li qub nto nro, defoams thiab inhibits ua npuas ncauj, tsis tshua muaj dej rhiab heev, muaj peev xwm ntub ntau yam substrates, tsis tsim micelles, muaj thermal stability, zoo acid-base stability. Kev ntub dej-raws li cov tshuab muaj qhov nro ntau dua li cov tshuab hnyav thiab yuav tsum tau ntxiv cov surfactants los txhim kho wettability. Txawm li cas los xij, cov tshuaj ntub dej ib txwm yuav ua rau ua npuas dej thiab ua npuas dej ruaj khov. Yog tias ntxiv defoamers, cov teeb meem ntub dej tsis zoo xws li pinholes yuav rov tshwm sim.
Nws tuaj yeem zam cov teeb meem no. Qhov kev ua tau zoo yog qhov zoo dua li cov tshuaj surfactants, thiab nws tuaj yeem muab qhov tsis tshua muaj qhov nro thiab ua npuas dej nyob rau hauv cov xwm txheej zoo.
Vim nws cov qauv molecular tshwj xeeb, defoaming cov khoom series surfactants yog ib tug zoo symmetrical non-ionic defoaming tus neeg saib xyuas.
Cov surfactant tsis muaj qhov taw tes huab thiab tuaj yeem muaj qhov ua kom ntev ntev ntawm qhov kub thiab txias. Dej rhiab heev Ntau cov surfactants ua rau muaj teeb meem dej rhiab heev ntawm cov coated nto tom qab ziab.
Hydrophilic surfactants siab heev xws li anionic (dioctyl sulfosuccinate sodium ntsev) los yog polyethoxylated surfactants tau yooj yim rov ua kom yaj hauv dej, ua rau muaj qhov tsis xws luag hauv cov txheej qhuav, xws li nplaum, plaub hau dawb, fogging, thiab dej tsis zoo.
Nws raug nquahu kom ntxiv 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 qhov sib txawv siab tshaj plaws rau hauv lub cev, yuav tsum tau ua kom tiav dispersion rau 15. -30 feeb. Qee qhov 2,4,7,9-Tetramethyl-5-decyne-4,7-diol series surfactants tuaj yeem crystallize thaum thauj lossis khaws cia ntawm qhov kub tsis tshua muaj; maj mam cua sov thaum lub sij hawm me ntsis dispersion yuav restore lawv zoo.
Pom zoo ntxiv qib USE:
Aqueous txheej: 0.1% -3.0%
Aqueous siab rhiab nplaum nplaum: 0.1% -1.0%
Kev daws teeb meem: 0.1% - 1.0%
Dav hlau ink: 0.1% -1.0%
Cov ntaub ntawv saum toj no yog tus nqi empirical, thiab qhov kev pom zoo npaum li cas yog txiav txim siab los ntawm ntau qhov kev sim
Qhov zoo:
Tshaj tawm sai heev, txo qis dynamic thiab zoo li qub nto nro, defoaming, thiab antifoaming, tsis tshua muaj dej rhiab heev, wetting ntau yam substrates yam tsis tsim micelles.zoo thermal stability thiab acid-alkali kuj.
Kev ntub dej:
Cov tshuab dej-raws li cov tshuab muaj siab dua li cov kuab siv hluav taws xob, thiab nws yog qhov yuav tsum tau ntxiv los txhim kho cov chaw ua haujlwm ntub dej feem ntau ua rau ua npuas dej thiab muaj teeb meem ruaj khov. Cov khoom lag luam tuaj yeem kov yeej cov teeb meem no, muab cov kev ua tau zoo tshaj plaws hauv kev muab qhov nro qis thiab defoaming txawm tias nyob rau hauv cov xwm txheej zoo.
Defoaming:
Cov surfactants series, nrog lawv cov qauv molecular tshwj xeeb, ua raws li cov neeg ua haujlwm zoo uas tsis yog-ionic defoaming. Lawv muaj peev xwm defoaming tsis tu ncua nyob rau hauv ib tug dav kub ntau yam tsis muaj clouding point.
Dej rhiab heev:
Ntau cov surfactants ua rau muaj teeb meem dej rhiab heev ntawm cov txheej txheej qhuav. Cov hydrophilic surfactants siab heev xws li anionic (dioctyl sulfosuccinate) los yog polyethoxylate surfactants yog yooj yim resolubilize hauv dej, ua rau deg tsis xws luag nyob rau hauv qhuav coatings xws li stickiness thiab whitening, atomization, thiab dej tsis zoo.
