Polyacrylamide (PAM) Ndi Kugwiritsa Ntchito Kwake Pakuchiritsa Madzi

Polyacrylamide (PAM) ndi ntchito yake pochiza madzi

Kuwongolera kuipitsidwa kwamadzi ndi kuwongolera ndi gawo lofunikira pakuteteza chilengedwe komanso kutaya madzi otayira kuchitiridwa chidwi kwambiri.

Polyacrylamide (PAM), liniya madzi sungunuka polima, ndi gawo lofunika kwambiri pa nkhani ya mankhwala madzi chifukwa cha kulemera kwa maselo, sungunuka madzi, lamulo la kulemera kwa maselo ndi zosiyanasiyana ntchito kusinthidwa.

PAM ndi zotumphukira zake zitha kugwiritsidwa ntchito ngati ma flocculants ogwira ntchito, thickening agent, drag reduction agent, omwe amagwiritsidwa ntchito kwambiri pokonza madzi, kupanga mapepala, mafuta, malasha, geology, zomangamanga ndi magawo ena ogulitsa.

M'madzi apansi, pamwamba pa madzi ndi zimbudzi, zonyansa ndi zowononga nthawi zambiri zimakhalapo monga tinthu tating'onoting'ono tomwe sitingathe kukhazikika pansi pa mphamvu yokoka.Chifukwa sedimentation zachilengedwe zalephera kukwaniritsa zofunikira, mothandizidwa ndi mankhwala kufulumizitsa kukhazikika kwaukadaulo kwagwiritsidwa ntchito popanga.Mwachitsanzo, molekyulu ya PAM imatenga tinthu zingapo ndikupanga floc yayikulu, chifukwa chake, kukhazikika kwa tinthu timachulukirachulukira.

Poyerekeza ndi inorganic flocculant, PAM ili ndi zabwino zingapo zofunika: zosinthika zambiri pamikhalidwe yosiyanasiyana, kuchita bwino kwambiri, kumwa pang'ono, matope ocheperako, osavuta kuchiritsa.Izi zimapangitsa kukhala flocculant yabwino kwambiri.

Ndi za mlingo wa inorganic coagulant 1/30 mpaka 1/200.

PAM imagulitsidwa m'njira ziwiri zazikulu: ufa ndi emulsion.

PAM ya ufa ndi yosavuta kunyamula, koma si yosavuta kugwiritsa ntchito (zida zowonongeka zimafunika), pamene emulsion siili yophweka kunyamula ndipo imakhala ndi moyo wautali wosungira.

PAM imakhala ndi kusungunuka kwakukulu m'madzi, koma imasungunuka pang'onopang'ono.Kusungunuka kumawononga maola angapo kapena usiku wonse.Kusakaniza bwino kwamakina kumathandizira kusungunula PAM.Onjezani pang'onopang'ono PAM kumadzi owirikiza - osati madzi ku PAM.

Kutentha kumatha kuwonjezera pang'ono kuchuluka kwa kusungunuka, koma kutentha sikuyenera kupitirira 60 ° C.

Kuphatikizika kwakukulu kwa PAM kwa yankho la polima ndi 0.5%, kuchuluka kwa PAM yapang'onopang'ono kumatha kusinthidwa kukhala 1% kapena kupitilira apo.

Yankho la PAM lokonzekera liyenera kugwiritsidwa ntchito masiku angapo, apo ayi ntchito ya flocculation idzakhudzidwa.
