Polyacrylamide
Polyacrylamide ndi liniya polima, mankhwala makamaka anawagawa ufa wouma mitundu colloidal awiri. Malinga ndi kuchuluka kwake kwama molekyulu, amatha kugawidwa m'magulu otsika (<1 miliyoni), kulemera kwapakatikati (2 ~ 4 miliyoni) ndi kulemera kwama molekyulu (> .7 miliyoni). Malinga ndi kapangidwe kake atha kugawidwa kukhala osakhala - ionic, anion ndi cationic. Kugawanika kwamadzi (HPAM) kwamtundu wa anion. Unyolo waukulu wa polyacrylamide uli ndimagulu ambiri amide, omwe ali ndimankhwala ambiri, ndipo amatha kusinthidwa kuti apange mitundu yambiri ya polyacrylamide. Zogulitsazi zakhala zikugwiritsidwa ntchito kwambiri pakupanga mapepala, kukonza mchere, kupanga mafuta, zitsulo, zomangira, zonyansa ndi mafakitale ena. Monga mafuta, kuyimitsa, dothi lolimbitsa, wothandizila kusamutsa mafuta, kuchepa kwamadzi ndi wothandizila, polyacrylamide yakhala ikugwiritsidwa ntchito pobowola, acidification, fracturing, plugging madzi, kulumikiza, kuchira mafuta sekondale komanso kuchira mafuta apamwamba.

Ntchito
1.kusindikiza ndi kudaya mankhwala amadzi ogwiritsidwa ntchito
Kusindikiza ndi kupaka utoto pamadzi am'madzi, m'malo mwa ma coagulants achikhalidwe otsika, pokhudzana ndi kuchuluka kwakukulu kwa coagulant, magwiridwe antchito a coagulation ndiokwera, momwe akadakwaniritsire motere: 8.0.
2.Papermaking madzi ogwiritsira ntchito zonyansa
Kupanga madzi ogwiritsidwa ntchito popanga madzi, omwe amagwiritsidwa ntchito ngati coagulant m'malo mwa polyaluminum chloride, aluminium sulphate, ndi zina zambiri, atha kugwiritsidwanso ntchito ngati kutsitsa sludge yopanga mapepala.
