Polyacrylamide ndi liniya polima, mankhwala makamaka ogaŵikana ufa youma ndi colloidal mitundu iwiri. Malingana ndi kulemera kwake kwa maselo, akhoza kugawidwa kukhala otsika kwambiri (<1 miliyoni), kulemera kwapakati (2 ~ 4 miliyoni) ndi kulemera kwakukulu kwa maselo (> .7 miliyoni) . - ionic, anion ndi cationic. Kuwonongeka kwamadzi (HPAM) kwa mtundu wa anion. Unyolo waukulu wa polyacrylamide uli ndi magulu ambiri a amide, okhala ndi ntchito zambiri zama mankhwala, ndipo amatha kusinthidwa kuti apange zotumphukira zambiri za polyacrylamide. Zogulitsazo zakhala zikugwiritsidwa ntchito kwambiri popanga mapepala, kukonza mchere, kuchotsa mafuta, zitsulo, zomangira, kuyeretsa zimbudzi ndi mafakitale ena. Monga lubricant, kuyimitsidwa wothandizira, dongo stabilizer, mafuta kusamuka wothandizila, kutaya madzi kuchepetsa wothandizila ndi thickening wothandizila, Polyacrylamide wakhala ankagwiritsa ntchito pobowola, acidification, fracturing, plugging madzi, cementing, yachiwiri mafuta kuchira ndi maphunziro apamwamba mafuta.

Kugwiritsa ntchito

1.kusindikiza ndi kudaya mankhwala madzi oipa

Kusindikiza ndi kudaya mankhwala amadzi akuwonongeka, m'malo mwa ma coagulants achikhalidwe otsika a molekyulu, poyerekeza ndi mulingo wawukulu wamankhwala wa coagulant, mphamvu ya coagulation ndiyokwera, ph mikhalidwe yabwino motere: 8.0.

2.Papermaking madzi otayira mankhwala

Papermaking madzi zinyalala mankhwala, amene ntchito ngati coagulant m'malo polyaluminium kolorayidi, zotayidwa sulfate, etc., Angagwiritsidwenso ntchito ngati dewatering wa papermaking sludge.
