Polyacrylamide (PAM), yomwe imadziwika kuti flocculant kapena coagulant, ndi ya coagulant.The pafupifupi molekyulu yolemetsa ya PAM imachokera ku masauzande mpaka makumi mamiliyoni a mamolekyu, ndipo pali magulu angapo ogwira ntchito pamodzi ndi mamolekyu omangika, ambiri omwe amatha kukhala ionized m'madzi, omwe ali a polima electrolyte. Malinga ndi makhalidwe a magulu ake dissociable anawagawa anionic Polyacrylamide, cationic Polyacrylamide, ndi nonionic polyacrylamide.
Ntchito
PAM ndiwokwera kwambiri, ndipo organic polymer flocculant imakhala ndi mawonekedwe owoneka bwino kwambiri popanga gulu lalikulu pakati pa tinthu ting'onoting'ono.
Makhalidwe
PAM ntchito flocculation, ndi flocculated mitundu pamwamba katundu, makamaka kuthekera kinetic, mamasukidwe akayendedwe, turbidity ndi pH mtengo wa kuyimitsidwa zikugwirizana ndi mphamvu kinetic wa tinthu pamwamba, ndi chifukwa cha tinthu kutsekereza kuwonjezera pamwamba mlandu moyang'anizana PAM, akhoza kupanga kinetic kuthekera kuchepa ndi kugwirizana. Polyacrylamide (PAM) ndi polima sungunuka madzi, insoluble mu zosungunulira zambiri organic, ali flocculation wabwino, akhoza kuchepetsa kukana kukangana pakati pa zakumwa. Kuchuluka kwa zolimba zoyimitsidwa m'madzi otayira sikuli kokwera, ndipo kulibe ntchito ya condensation. M'nyengo yamvula, tinthu tating'onoting'ono sizisintha mawonekedwe awo, komanso sagwirizana wina ndi mzake, ndipo aliyense amamaliza ndondomeko yamvula payekha.
Kugwiritsa ntchito
PAM imagwiritsidwa ntchito makamaka pochotsa matope, kupatukana kwamadzi olimba komanso kubwezeretsanso kutsuka kwa malasha, kukonza mchere ndi madzi otayira pamapepala. Itha kugwiritsidwa ntchito pochiza madzi otayira m'mafakitale komanso zimbudzi zapakhomo zam'tawuni. M'makampani opanga mapepala, PAM ikhoza kupititsa patsogolo mphamvu yowuma ndi yonyowa ya pepala, kupititsa patsogolo kusungirako ulusi wabwino ndi fillers.PAM ingagwiritsidwenso ntchito ngati chowonjezera pamatope omwe amagwiritsidwa ntchito m'munda wa mafuta ndi pobowola geological.
Mapeto
Monga wothandizira wofunikira wothira madzi, PAM imagwira ntchito yofunika kwambiri pakuyeretsa madzi ndi kuyeretsa zimbudzi. Imatha kuchotsa mwachangu komanso moyenera zinthu zoyimitsidwa, ma colloids ndi organic zinthu m'madzi, kupititsa patsogolo chithandizo chamankhwala komanso kuyeretsa madzi. PAM ili ndi ntchito zambiri. Pogwiritsa ntchito PAM poyeretsa madzi, tikhoza kukonza malo abwino a madzi, kuteteza ndi kupititsa patsogolo kagwiritsidwe ntchito kabwino ka madzi, ndikupanga mikhalidwe yabwino pa moyo wa anthu ndi chitukuko.
