Mokhoa oa ho sebelisa defoamer bakeng sa ho etsa pampiri

Nakong ea tlhahiso ea indasteri, ho tla hlahisoa li-foam tse ngata tse kotsi, 'me defoamer e hloka ho eketsoa. E sebelisoa haholo ho tlosa foam e kotsi e hlahisoang molemong oa tlhahiso ea latex, saizi ea masela, ho belisoa ha lijo, biomedicine, coating, petrochemical, ho etsa pampiri, ho hloekisa indasteri le liindasteri tse ling.Emulsion ea siliconeTlhokomeliso ea tšebeliso ea defoamer: pele o sebelisoa kapa sampole e hloka ho hlohlelletsa emulsion ka botlalo. Emulsion ea oli e ka metsing e ka hlapolloa ka mokhoa o ikhethileng, empa ka nako e ts'oanang, botsitso ba emulsion le bona bo tla fokotseha haholo, joalo ka stratification. Ha u hlapolla, ka kopo eketsa metsi ho defoamer 'me u tsose butle. Kaha emulsion e tsitsitse ka ho fetisisa nakong ea eona ea pele, emulsion e hlapollotsoeng e tlameha ho sebelisoa ka nako e khutšoanyane. Li-emulsions li na le kutloelo-bohloko 'me li kotsing ea serame le mocheso o ka holimo ho 40°C. Itšireletse khahlanong le serame! Litlolo tse hatselitsoeng li ka ntšoa ka hloko serameng, empa li tlameha ho hlahlojoa pele li sebelisoa hape. Li-oscillations tse matla kapa ho kuta ka matla (tse kang ho sebelisa pompo ea mechine, homogenizer, joalo-joalo) kapa ho susumetsa nako e telele ho tla senya botsitso ba emulsion. Ho eketsa viscosity ea emulsion kapa ho eketsa thickener ho ka ntlafatsa botsitso ba emulsion.
