Polyacrylamide imatchedwa PAM, ndipo imagawidwa mu anion (HPAM) ndi cation (CPAM).Nonionic (NPAM) ndi polima liniya ndipo ndi imodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri popanga polima osungunuka m'madzi.Ndipo zotumphukira zake angagwiritsidwe ntchito ngati flocculants ogwira, thickeners, wothandizila pepala kulimbikitsa ndi kukoka reducers madzi, etc., ankagwiritsa ntchito mankhwala madzi, papermaking, mafuta, malasha, migodi ndi zitsulo, geology, nsalu, zomangamanga, etc. Industrial gawo.
Polyacrylamide amatchedwa No. 3 coagulant, flocculant No. 3;amatchedwa PAM;nthawi zambiri amatchedwa retention aid popanga mapepala ndi mafakitale ena.Pakalipano, mankhwala omwe amaperekedwa ndi kampani yathu ndi olimba (ufa wouma) ndi emulsion.
Polyacrylamide lagawidwa anionic Polyacrylamide;cationic polyacrylamide;nonionic polyacrylamide;zwitterionic polyacrylamide;Dzina lachingerezi;PAM (acrylamide).
Mfundo yochitira zinthu
1) Mfundo ya flocculation: pamene PAM imagwiritsidwa ntchito poyendetsa, imagwirizana ndi malo amtundu wamtundu wa flocculation, makamaka mphamvu ya kinetic, viscosity, turbidity ndi pH mtengo wa kuyimitsidwa.Mphamvu yamphamvu ya tinthu padziko lapansi ndi chifukwa cholepheretsa tinthu.PAM yokhala ndi zotsutsana zotsutsana imatha kuchepetsa kuthekera kwa kinetic ndikuphatikiza.
2) Adsorption ndi bridging: PAM molekyulu unyolo anakonza pamwamba pa particles zosiyanasiyana, ndi polima milatho aumbike pakati pa particles, kotero kuti particles kupanga aggregates ndi kukhazikika.
3) Kutsatsa kwapamtunda: ma adsorption osiyanasiyana a tinthu tating'ono ta polar pa mamolekyu a PAM.
4) Kulimbitsa: Unyolo wa PAM wa molekyulu ndi gawo lobalalika limaphatikiza gawo lobalalika pamodzi kudzera pamakina osiyanasiyana, thupi ndi mankhwala kuti apange maukonde.
