1 Tsis yaj los yog tsis yaj zoo hauv cov kua ua npuas txhais tau tias cov ua npuas tawg lawm, thiabtshuaj ua npuas ncaujyuav tsum tau sib xyaw thiab sib xyaw rau ntawm daim zaj duab xis ua npuas ncauj. Rau cov tshuaj defoamer, nws yuav tsum tau sib xyaw thiab sib xyaw tam sim ntawd, thiab rau cov tshuaj defoamer, nws yuav tsum khaws cia rau hauv lub xeev no tas li.
Yog li ntawd, tus neeg ua npuas dej nyob rau hauv lub xeev supersaturated hauv cov kua ua npuas dej, thiab nws yooj yim mus txog lub xeev supersaturated tsuas yog tias nws tsis yaj lossis tsis yaj zoo. Tsis yaj lossis tsis yaj zoo, nws yooj yim sib sau ua ke ntawm qhov sib txuas ntawm cov roj-kua, yooj yim rau kev tsom mus rau ntawm zaj duab xis ua npuas dej, thiab tuaj yeem ua lub luag haujlwm ntawm qhov concentration qis dua. Rau cov neeg ua npuas dej siv hauv cov txheej txheem dej, cov molecules ntawm cov khoom xyaw nquag yuav tsum yog hydrophobic muaj zog thiab tsis muaj zog hydrophilic, thiab tus nqi HLB yuav tsum nyob rau hauv qhov ntau ntawm 1.5-3 kom ua haujlwm zoo tshaj plaws.
2 Qhov kev nruj ntawm qhov chaw qis dua li ntawm cov kua ua npuas. Tsuas yog thaum lub zog intermolecular ntawm cov tshuaj defoamer me me thiab qhov kev nruj ntawm qhov chaw qis dua li ntawm cov kua ua npuas, cov khoom defoamer tuaj yeem raug raus thiab nthuav dav ntawm cov zaj duab xis ua npuas. Nws tsim nyog sau tseg tias qhov kev nruj ntawm qhov chaw ntawm cov kua ua npuas tsis yog qhov kev nruj ntawm qhov chaw ntawm cov tshuaj, tab sis qhov kev nruj ntawm qhov chaw ntawm cov tshuaj ua npuas.
3. Muaj qee qib sib raug zoo nrog cov kua ua npuas. Vim tias cov txheej txheem defoaming yog qhov sib tw ntawm qhov ceev ntawm kev tawg ntawm cov npuas thiab qhov ceev ntawm kev tsim cov npuas, cov tshuaj defoamer yuav tsum muaj peev xwm tawg sai hauv cov kua ua npuas kom nws tuaj yeem ua lub luag haujlwm sai hauv ntau yam ntawm cov kua ua npuas. Yuav kom cov tshuaj defoamer kis tau sai dua, cov khoom xyaw nquag ntawm cov tshuaj defoamer yuav tsum muaj qee qib sib raug zoo nrog cov kua ua npuas. Yog tias cov khoom xyaw nquag ntawm cov tshuaj defoamer nyob ze rau cov kua ua npuas, lawv yuav yaj; yog tias lawv nyob deb dhau, lawv yuav nyuaj rau tawg. Tsuas yog thaum qhov sib raug zoo tsim nyog, qhov cuam tshuam yuav zoo.
4. Tsis muaj tshuaj lom neeg ua rau cov kua ua npuas. Cov tshuaj ua npuas yuav ua rau cov kua ua npuas. Ib sab tes, cov tshuaj ua npuas yuav poob nws cov txiaj ntsig, thiab sab tod tes, cov tshuaj lom neeg yuav tsim tawm, cuam tshuam rau kev loj hlob ntawm cov kab mob me.
5. Kev hloov pauv tsawg thiab lub sijhawm ua haujlwm ntev. Ua ntej, txiav txim siab seb lub kaw lus twg yuav tsum siv cov tshuaj defoamer, seb nws yog lub kaw lus uas siv dej lossis lub kaw lus uas siv roj. Piv txwv li, hauv kev lag luam fermentation, cov tshuaj defoamer uas siv roj xws liYuav tsum siv cov polyether-modified silicone lossis polyether. Kev lag luam txheej txheej uas siv dej yuav tsum siv cov tshuaj defoamers uas siv dej thiab cov tshuaj silicone defoamers. Xaiv cov tshuaj defoamer, piv rau qhov ntxiv, thiab saib tus nqi kom tau cov tshuaj defoamer uas tsim nyog thiab pheej yig tshaj plaws.
