Dab tsi yog antifoam hauv kev kho dej kom dej khov?

Tus tsuj, tseem hu ua defosamer, yog cov tshuaj lom neeg ntxiv siv nyob rau hauv kev kho dej kom muaj kev kho kom muaj kev kho kom muaj kev tsim ua npuas. Ua npuas ncauj yog ib qho teeb meem hauv cov ntoo lim dej pov tseg thiab tuaj yeem tshwm sim los ntawm ntau qhov chaw xws li cov teeb meem organic, surfactants, lossis ntxhov siab ntawm cov dej. Thaum ua npuas ncauj yuav zoo li tsis muaj zog, nws tuaj yeem cuam tshuam cov txheej txheem kev kho kom zoo los ntawm kev siv nyiaj txiag, thiab muaj peev xwm ua rau muaj teeb meem lossis nqa khoom.

Oantifoam cov neeg sawv cev ua haujlwm los ntawm Destabilizing Ua npuas ncauj npuas, ua rau lawv vau lossis ua npuas dej ntim thiab tiv thaiv nws los ntawm kev cuam tshuam nrog kev kho mob cov txheej txheem. Cov tshuaj tiv thaiv no feem ntau muaj kev sib xyaw ntawm surfactants, roj, silicones, lossis lwm yam tshuaj hydlicobic. Thaum ntxiv rau lub pov tseg, cov neeg sawv cev tiv thaiv kev tsiv mus rau saum npoo ntawm cov npo thiab cuam tshuam rau cov npoo av, ua rau cov npuas npuas.

Muaj ntau ntau hom kev sawv cev ntawm cov tub rog siv hauv kev kho kom muaj dej khov, txhua tus nrog nws tus kheej cov khoom tshwj xeeb thiab cov ntawv thov:

Silicone-based antifoams:

Cov no yog cov feem ntau siv cov tshuaj tiv thaiv cov kwv yees vim lawv cov txiaj ntsig thoob plaws ntau qhov kev mob. Silicone-raws cov tshuaj tiv thaiv yog qhov ruaj khov, insoluble hauv dej, thiab tuaj yeem tsim cov txheej txheem kom tau sib haum nrog ntau yam kev kho dej kom zoo.

Qhov Zoo ntawm Organosilicon Defoamers:

Tshuaj lom neeg zoo inertness, tsis tau hnov ​​mob nrog lwm cov tshuaj, tuaj yeem siv rau acidic, alkaline, thiab qab ntsev

Kev ua haujlwm zoo hauv lub cev, haum rau kev siv hauv cov zaub mov thiab cov tshuaj lag luam, kev qias neeg tsis muaj kuab paug

Nruab Nrab Thermal Stability, qis tsis pub luam tawm, thiab tuaj yeem siv dhau qhov ntsuas kub ntau

Tsis muaj viscosity, sai tau nthuav tawm ntawm roj-kua interface

Lub nro yog qis li 1.5-20 mn / m (dej yog 76 mn / m)

Tsis yog soluble hauv surfactants ntawm foaming nruab

Tsawg npaum li cas, qis viscosity, thiab cov nplaim roj tsawg

Cov tshuaj tiv thaiv polymicic:

Cov neeg sawv cev antifoam no yog raws cov polymers uas cuam tshuam ua npuas ncauj tsim los ntawm adsorbing mus rau saum npoo ntawm npuas npuas thiab hloov lawv qhov ruaj khov. Cov tshuaj tiv thaiv polymicies feem ntau siv nyob rau hauv cov xwm txheej uas cov neeg sawv cev rau cov neeg sawv cev ua haujlwm tsis zoo, xws li inclic wastewater tej yam.

Lwm cov antifoams:

Hauv qee kis, cov khoom siv hluav taws xob silicone-raws li yuav tsis haum vim muaj kev txhawj xeeb thev naus laus zis lossis kev xav tau tshwj xeeb. Tsis-silicone antifoams, xws li cov roj ntxhia-raws li lossis rog acid-based antifooss, muaj kev xaiv ib puag ncig uas yuav yog tus phooj ywg ib txwm muaj los sis zoo dua rau qee cov ntawv thov.

Hmoov rau antifoams:

Qee tus neeg sawv cev tiv thaiv kab mob muaj nyob hauv daim foos, uas tuaj yeem ua tau zoo hauv kev siv cov khoom siv ua kua tsis muaj txiaj ntsig lossis qhov twg lub sijhawm ntev antifoam kev ua ub no.

Cov neeg xaiv ntawm tus neeg sawv cev tsim nyog ntawm Antifoam nyob ntawm qhov xwm txheej xws li cov xwm txheej ntawm cov neeg pov hwm, kev kho mob tshwj xeeb tau ua haujlwm, thiab kev txiav txim siab tau txais kev cai. Ntxiv rau kev xaiv cov antifoam tus neeg sawv cev zoo, kev siv tshuaj thiab cov ntawv thov yog qhov tseem ceeb ua kom muaj kev cuam tshuam ua npuas dej zoo.

Thaum cov neeg sawv cev rau cov neeg sawv cev ua haujlwm tau ua npuas ncauj siv rau cov txheej txheem kev tiv thaiv tsis tu ncua xws li cov txheej txheem kho mob los yog kev tso tawm ntawm cov tshuaj muaj teeb meem mus rau ib puag ncig. Kev tshuaj xyuas cov qib ua npuas ncauj li cas raws li cov kev tswj hwm ua kom zoo thaum tsis muaj kev cuam tshuam zoo rau kev ua kom muaj kev ua kom zoo thiab ib puag ncig.
