Muaj ntau yamDefoamersThiab lawv tau siv dav. Cov txheej txheem ntawm "Ua Npuas Ncauj" thiab "Ua Npuas Ncauj" ntawm Defoamer yog ntxiv rau ntawm cov kab, inhibiting qhov kev tsim ntawm zaj duab xis elastic, uas yog, txiav tawm tiam neeg ua npuas ncauj. Thaum lub kaw lus tsim cov nyiaj ua npuas dej loj, ntxiv cov molecules sai sai no sib kis, nkag mus rau hauv cov khaubncaws sab nraud povtseg, thiab hloov cov txheej nyias nyias ntawm cov yeeb yaj kiab thawj zaug. Vim nws cov npoo qis nro, nws ntws mus rau cov kua uas muaj qhov sib cuam tshuam zoo, yog li ntawd kev nkag mus nruab nrab ntawm cov kua roj av, ua rau cov yeeb yaj kiab phab ntsa nrawm nrawm, thiab cov Ua npuas ncauj kuj cuam tshuam los ntawm ib puag ncig nplaim. Zaj duab xis txheej nrog siab nro rub tawm muaj zog, yog li kev ntxhov siab nyob ib ncig ntawm lub npaus yog tsis sib xws, uas ua rau nws "ua npuas ncauj tawg". Lub defoamer lwg me uas yog insoluble hauv lub system yuav rov nkag mus rau lwm zaj duab xis ua npuas, thiab lwm yam ua npuas ncauj yuav raug rhuav tshem tag.
Yuav ua li cas xaiv qhov raugTus tsuj
Kev tsim khoom thiab kev tsim kho ntawm cov txheej txheej yuav tsim cov npuas rau qib sib txawv. Ib tiam ntawm bubbles hov kev txhim kho ntawm kev txhim kho ntawm kev tsim khoom thiab kev tsim kho, thiab tib lub sijhawm nqa khoom tsis xws luag tiav rau cov yeeb yaj kiab tiav. Qhov tseeb xaiv ntawm ib qho tsim nyog defoamer tuaj yeem ua kom cov txheej txheem kev nce qib thiab kev tsim kho.
Cov haujlwm ntawm defoamer: Ua kom cov kua zaj duab xis nyob rau saum npoo ntawm npuas, tiv thaiv kev tsim ntawm npuas thiab txhawb nqa kev sib tsoo ntawm npuas. Tus defoamer yog siv rau cov npuas loj, thiab microfoam xav tau siv ua ke nrog degassing thiab defoaming.
Defoamer Nta: Tus defoamer yog insoluble nyob rau hauv nruab nrab, tab sis tuaj yeem nkag mus thiab tawg hauv nruab nrab hauv daim ntawv microdrotse. Qhov kev ua haujlwm zoo tshaj plaws ntawm kev defoober microdrots yog sib npaug rau cov tuab tuab ntawm lub phab ntsa npuas.
Defoamer muaj pes tsawg leeg:DefoamersRau cov dej-ua cov khoom kws kos duab kos duab tau muab faib ua cov khoom seem uas tsis muaj si-silicon thiab silicon-muaj. PaDefoamersyog tsim ntawm cov hauv qab no:
Nquag tshuaj: nws ua raws li kev ua npuas dej-tawg thiab defoaming tus neeg sawv cev nrog cov nro qis. Cov neeg sawv cev suav nrog tsiaj thiab roj zaub, hydrophobic silica, ntau dua cov dej cawv, thiab lwm yam.
Diffusion Tus neeg sawv cev: Wedting emulsifier kom paub meej tias qhov defoaming micro-dropse kev sib kis thiab hu rau npuas zaj duab xis thiab kis tau. Muaj tsis yog (orikl) phenol polyoxyylene ether, xab npum ntsev thiab lwm yam.
Cov cab kuj: Nws pab cov tshuaj nquag los ua ke nrog cov foaming system, thiab yooj yim rau tawg mus rau hauv cov foaming system. Sib txuas ob, nws muaj cov nro qis qis, pab kom ua npuas ncauj ua npuas, thiab tuaj yeem txo tus nqi.
Ob qho xwm txheej yuav tsum tau ntsib rau defoaming: E = γ2 + γ3 + γ3> 0, txhawm rau paub meej tias qhov tsis txaus ntseeg rau hauv lub phab ntsa ua npuas ncauj; Kis Tau Zoo S = γ1-V12-γ-γ-γ3> 0, kom ntseeg tau tias qhov kev cuam tshuam defusts sib txawv kis hauv cov ntawv xov xwm ua npuas ncauj.
