Tus yuam sij rau kev siv Defoamers yog xaiv cov hom yog, kev tswj hwm cov tshuaj, siv txoj cai ntxiv, thiab xyuam xim rau cov txheej txheem sib xws thiab kev ua haujlwm.
Cov kauj ruam tshwj xeeb thiab kev ceev faj:
Xaiv cov hom txoj cai ntawm defoamer
Xaiv cov khoom siv dag raws li cov txheej txheem system ua haujlwm (PH, ntsuas kub, tshuaj lom neeg, thiab lwm yam):
Silicon hom: Cov nyhuv defoaming zoo thiab noj ntau, tab sis yuav ua rau shrinkage thiab lwm yam teeb meem. Hom Polyether: kub thiab kua qaub thiab cov kua qaub, tab sis cov nyhuv tsis muaj zog. Ntxuj roj hom: tus nqi qis tab sis tej zaum yuav cuam tshuam rau cov pob tshab ntawm lub system. Ua cov kev sim me thiab sim thaum tsim nyog los ntsuas cov nyhuv defoaming thiab cuam tshuam rau lub system: piv txwv li, simulate cov xwm txheej hauv chav kuaj thiab cov kab ntau lawm.
Txheeb xyuas qhov zoo tshaj plaws muab rau cov lus qhia (feem ntau {{}}}}}.
Muaj chaw nyob ua ke tso cai ntxiv ntxiv kom txog thaum lub npaus tau tshem tawm, tab sis cov zaub mov ntxiv yuav tsum nruj raws cov qauv.
Siv cov txheej txheem ntxiv nws yog qhov ua tau zoo dua ntxiv ua ntej cov ua npuas ncauj yog tsim tawm: piv txwv li, ntxiv cov kab lis kev cai lossis ntxiv cov xim sib xyaw ua ntej sib xyaw cov xim.
Ntxiv rau hauv Batches: Tsim nyog rau kev ua npuas dej loj, xws li ntxiv rau hauv cov batches hauv cov ntu sib txawv ntawm papermaking.
Ntxiv tom qab dilution: high-concenutation defroamers yuav tsum tau dilontaminated cov kais dej (dej kub yog tswj hwm ntawm 5% {%.
Ib qho ntxiv ntawm txoj kev hauv cov ntaub ntawv sib txawv: kua: nrog lossis tshuaj tsuag.
Khoom: qhov chaw ntawm cov dej phwj dej rau kev txiav txim siab.
Hmoov: Cov kws tshaj lij ntxiv rau txim tsis tu ncua.
Cov kev ceev faj tsis txhob muaj ntau dhau los: Nws yuav ua rau shrinkage, muag muag lossis qhov ci ntawm cov khoom.
MaDitate Stirring Ceev: dhau nrawm yuav qhia cov tshiab ua npuas, qeeb dhau yuav ua rau muaj kev sib cais tsis sib xws.
Qhov kub nyhuv: qee qhov tiv thaiv tsis tshua muaj kev nquag kub ntawm qhov kub.
Kev xeem sib xws: kom paub tias tsis muaj kev phiv tsis zoo ua ntej thov cov txheej txheem tshiab.
Piv txwv li, cov roj fatty acids muaj txiaj ntsig zoo nyob rau hauv cov xwm txheej acidic, tab sis yuav ua npuas ncauj cov neeg sawv cev raws li Alkaline tej yam kev mob.
Kev ceev faj kev nyab xeeb: Qee tus neeg tiv thaiv tsis txaus ntseeg rau daim tawv nqaij lossis qhov muag.
