Txoj kev ntawm kev siv Defoamer rau papermaking

Nyob rau hauv cov txheej txheem ntawm kev tsim khoom lag luam, muaj ntau yam kev ua npuas ncauj yuav raug tsim tawm, thiab defonamer xav tau ntxiv. Nws yog dav siv los tshem cov kev ua npuas dej ua rau cov txheej txheem ntau lawm ntawm cov yas, textile sizing, txheej, petrochemical, ntawv tais thiab lwm yam kev lag luam.Silicone emulsionDefoamer Siv ceeb toom: ua ntej siv lossis kuaj yuav tsum tau ua kom tiav qhov emulsion. Roj-hauv-dej emulsion tuaj yeem ua rau cov neeg tsis siab, tab sis tib lub sijhawm, qhov ruaj khov ntawm emulsion tseem yuav tsis kam ua kom loj, xws li stratification. Thaum diluting, thov ntxiv dej rau ntawm defoamer thiab tshem maj mam. Txij li thaum emulsion yog qhov zoo tshaj plaws nyob rau ntawm nws qhov tseem ceeb, cov emulsilation diluted yuav tsum tau siv nyob rau hauv ib lub sijhawm luv luv. Emulsions muaj rhiab thiab muaj txiaj ntsig rau te thiab kub siab tshaj 40 ° C. Tiv thaiv Frost! Lotions uas muaj khov tuaj yeem ua tib zoo muab tshem tawm los ntawm te, tab sis yuav tsum tau kuaj ua ntej siv. Cov khoom siv hluav taws xob muaj zog lossis muaj zog shearing (xws li siv lub twj tso tshuab, homogenizer, thiab lwm yam) lossis nplawm kom rhuav tshem cov ruaj khov ntawm emulsion. Kev nce qib viscosity ntawm emulsion lossis ntxiv cov tuab tuaj yeem txhim kho kev ruaj ntseg ntawm cov emulsion.

① Yuav tuaj yeem diluted nrog dej huv 1-3 lub sij hawm poob rau hauv slurry pas dej, lub thawv siab, mesh trough thiab lwm yam npuas; Tus nqi ntawm foaming system rau 0.01% -0.2%; Cov khoom yuav tsum yog diluted kom sai li sai tau nyob rau lub sijhawm luv luv.

Nyob rau hauv lub pulp zeb, lub defoamer feem ntau ntxiv rau hauv cov tshuaj dawb thiab ntxuav seem, thiab feem ntau ntxiv rau hauv cov tshuab ntxhua khaub ncaws, tuab thiab pulp tank. Lub defosamer hauv daim ntawvKoom rau seemFeem ntau ntxiv rau lub ntawv tshuab Flow Box, pulp pas, txheej thiab sizing xovxwm.

Nws yog feem ntau tus nqi ua tau zoo siv ob qho kev tiv thaiv ntau dua li siv tus nqi siab dua ntawm ib qho kev tiv thaiv ntau dua, ntxiv sib cais ntawm cov chaw deb. Piv txwv li, ib qho tiv thaiv yog ntxiv rau ntawm lub beater thiab lwm qhov ntxiv rau hauv lub thawv txaus.
