Kev ceev faj rau kev siv polyacrylamide:
1. Powdered los yog granular polyacrylamide tsis tuaj yeem ncaj qha ntxiv rau cov dej phwj tuaj. Nws yuav tsum tau yaj hauv dej ua ntej siv, thiab tom qab ntawd nws cov tshuaj aqueous yuav tsum tau ntxiv rau cov kav dej hauv ib qho kev faib ua feem.
2. Cov dej rau cov khoom tawg yuav tsum yog cov dej huv huv, thiab PH tus nqi ntawm cov kais dej tuaj yeem ua tau raws li qhov yuav tsum tau ua rau kev npaj cov tshuaj flocculant. 3. Cov dej kub yuav tsum tsis pub tshaj 60 degree, qhov kub thiab txias yog txaus.
4. Qhov concentration ntawm polyacrylamide PAM tov yog feem ntau yog 0.1 ~ 0.5 feem pua, uas yog, 15 grams hmoov yog ntxiv rau 1 liter dej.
5. Vim tsis zoo shear kev ua tau zoo ntawm polyacrylamide, cov khoom yuav degraded tom qab lub sij hawm ntev thiab kev kub ceev stirring, uas yuav txo tau nws cov nyhuv siv. Feem ntau, lub stirring ceev yuav tsum yog 60 ~ 120 rpm thaum dissolution.
6. Nyob rau hauv tus txheej txheem ntawm dissolution, qhov ceev ntawm ntxiv flocculant yuav tsum tau qeeb li sai tau, thiab nyob rau tib lub sij hawm, nws yuav tsum tau sprinkled rau hauv dej vortex maj mam kom tsis txhob flocculant hais los ntawm sticking ua ke tom qab nkag mus rau hauv dej.
