1 Insoluble lossis tsis zoo soluble hauv cov kua npuas ua npuas txhais tau tias cov npuas dej tawg, thiab covdefoobyuav tsum muaj concentrated thiab concentrated ntawm foam zaj duab xis. Rau qhov defoamer, nws yuav tsum muaj lub ntsej muag thiab feeb meej tam sim ntawd, thiab rau qhov defosamer, nws yuav tsum tau khaws cia hauv lub xeev no.
Yog li ntawd, tus defosamer yog nyob rau hauv ib lub xeev supersaturated hauv cov ua npuas dej, thiab nws yog qhov yooj yim mus txog lub xeev supersaturated tsuas yog tias nws yog insoluble lossis tsis zoo soluble lossis tsis zoo soluble lossis tsis zoo soluble lossis tsis zoo soluble lossis tsis zoo soluble lossis soluble tsis zoo. Insoluble lossis tsis zoo soluble, nws yog ib qho yooj yim los sib sau ua ke ntawm cov kua roj ua kua, yooj yim rau cov yeeb yaj kiab ua npuas ncauj, thiab tuaj yeem ua lub luag haujlwm ntawm kev sib luag. Rau kev tiv thaiv cov dej, cov lwg me me ntawm cov khoom xyaw nquag ua haujlwm thiab tsis muaj txiaj ntsig hydrophilic, thiab tus nqi HLB yuav tsum yog nyob rau hauv ntau ntawm 1.5-3 ua haujlwm zoo tshaj plaws.
2 Lub nro sab nro yog qis dua li cov ua npuas dej. Tsuas yog thaum muaj kev sib txuam nrog lub zog tsis sib haum xeeb yog qhov nruj thiab cov khoom siv tsis zoo yog qhov tso ua npuas ncauj, tuaj yeem tso tseg tau muab tso tawm thiab nthuav dav ntawm cov yeeb yaj kiab ua npuas ncauj. Nws yog tsim nyog sau cia tias qhov nro muaj qhov nro ntawm cov kua npuas tsis yog qhov nro ntawm cov tshuaj, tab sis cov npoo nro ntawm cov tshuaj foaming.
3. Ib qho degree ntawm kev sib txawv nrog cov ua npuas dej. Txij li thaum cov txheej txheem defoaming yog qhov kev sib tw ntawm kev ceev ntawm kev ua npuas ncauj, yuav tsum tau ua npuas dej nrawm nrawm kom nws thiaj li ua tau cov khoom siv dav dav ntawm cov ua npuas dej. Txhawm rau ua kom cov defoamer diffuse sai dua, cov khoom xyaw nquag ntawm defoob yuav tsum muaj qee qib ntawm kev ua kua. Yog tias cov khoom xyaw nquag ntawm cov defoamer yog ib yam nkaus thiab ze rau cov kua npuas, lawv yuav yaj; Yog tias lawv nyob deb dhau, lawv yuav nyuaj rau kev tawg. Tsuas yog thaum lub affinity yog qhov tsim nyog, cov nyhuv yuav zoo.
4. Tsis muaj tshuaj lom neeg nrog cov npuas dej. Tus defoamer reacts nrog cov ua npuas dej. Ntawm ib sab tes, tus defosamer yuav poob nws cov nyhuv, thiab lwm txhais tes, cov tshuaj muaj teeb meem yuav raug tsim tawm, cuam tshuam rau kev loj hlob ntawm cov kab mob me me.
5. Tsis muaj lub sijhawm tsis muaj sijhawm thiab sijhawm ntev. Ua ntej, txiav txim siab lub system uas cov neeg dag xav tau yuav tsum tau siv, txawm nws yog dej ua haujlwm lossis siv roj. Piv txwv, hauv kev lag luam fermentation, roj furcoamers xws liPolyether-hloov silicone lossis polyether yuav tsum tau siv. Kev lag luam dej-raws li txheej kev lag luam yuav tsum tau siv cov dej-raws li defoamers thiab silicone defoamers. Xaiv cov defoamer, piv tus nqi ntxiv, thiab xa mus rau tus nqi kom tau txais cov khoom lag luam uas haum thiab kev lag luam txaus siab tshaj plaws.
