1 Insoluble los yog tsis zoo soluble nyob rau hauv cov kua foaming txhais tau tias cov npuas dej tawg, thiab covdefoameryuav tsum tau concentrated thiab concentrated rau ntawm daim duab ua npuas ncauj. Rau lub defoamer, nws yuav tsum tau concentrated thiab concentrated tam sim ntawd, thiab rau lub defoamer, nws yuav tsum nco ntsoov khaws cia rau hauv lub xeev no.
Yog li ntawd, lub defoamer yog nyob rau hauv ib tug supersaturated lub xeev nyob rau hauv lub foaming kua, thiab nws yog ib qho yooj yim mus cuag ib tug supersaturated lub xeev tsuas yog hais tias nws yog insoluble los yog tsis zoo soluble. Insoluble los yog tsis zoo soluble, nws yog ib qho yooj yim los mus sib sau ua ke ntawm cov roj-kua interface, yooj yim rau kev mloog zoo rau cov ua npuas ncauj zaj duab xis, thiab muaj peev xwm ua si lub luag hauj lwm ntawm ib tug qis concentration. Rau defoamers siv nyob rau hauv dej systems, cov molecules ntawm cov khoom xyaw nquag yuav tsum muaj zog hydrophobic thiab tsis muaj zog hydrophilic, thiab HLB tus nqi yuav tsum nyob rau hauv thaj tsam ntawm 1.5-3 mus ua hauj lwm zoo tshaj plaws.
2 Lub nto nro yog qis dua li ntawm cov kua foaming. Tsuas yog thaum lub zog intermolecular ntawm lub defoamer me me thiab qhov nro ntawm qhov chaw qis dua li cov kua foaming, cov khoom defoamer tuaj yeem muab tso rau hauv thiab nthuav dav ntawm cov yeeb yaj kiab ua npuas ncauj. Nws yog tsim nyog sau cia tias qhov nro ntawm cov kua foaming tsis yog qhov nro ntawm cov tshuaj, tab sis qhov nro ntawm cov tshuaj foaming.
3. Ib qho degree ntawm affinity nrog cov kua foaming. Txij li thaum cov txheej txheem defoaming tiag tiag yog kev sib tw ntawm qhov nrawm ntawm cov npuas dej thiab qhov ceev ntawm kev ua npuas dej, lub defoamer yuav tsum muaj peev xwm ua kom tawg sai sai hauv cov kua foaming kom nws tuaj yeem ua lub luag haujlwm sai ntawm ntau yam ntawm cov kua foaming. Ua kom lub defoamer diffuse sai dua, cov khoom xyaw nquag ntawm defoamer yuav tsum muaj qee qhov kev sib raug zoo nrog cov kua foaming. Yog tias cov khoom xyaw nquag ntawm cov defoamer yog ze rau cov kua foaming, lawv yuav yaj; yog lawv nyob deb heev, lawv yuav nyuaj rau kev tawg mus. Tsuas yog thaum qhov kev sib raug zoo tsim nyog, cov nyhuv yuav zoo.
4. Tsis muaj tshuaj tiv thaiv nrog cov kua foaming. Lub defoamer reacts nrog cov kua foaming. Ntawm qhov tod tes, tus defoamer yuav poob nws cov txiaj ntsig, thiab ntawm qhov tod tes, cov khoom tsis zoo yuav raug tsim, cuam tshuam rau kev loj hlob ntawm cov kab mob.
5. Tsawg volatility thiab lub sijhawm ua haujlwm ntev. Ua ntej, txiav txim siab txog qhov system uas yuav tsum tau siv lub defoamer, seb nws puas yog dej-raws li system lossis roj-raws li system. Piv txwv li, hauv kev lag luam fermentation, roj-raws li defoamers xws lipolyether-hloov silicone los yog polyether yuav tsum tau siv. Kev lag luam txheej txheej dej yuav tsum siv dej-raws li defoamers thiab silicone defoamers. Xaiv cov defoamer, sib piv cov nyiaj ntxiv, thiab xa mus rau tus nqi kom tau txais cov khoom tsim nyog tshaj plaws thiab kev lag luam defoamer.
