Polyacrylamide (Pam) ndi ntchito yake mumadzi

Kuwonongeka kwa kuwonongeka kwa madzi ndi ulamuliro ndi gawo lofunikira pakuteteza zachilengedwe ndikuchotsa mankhwalawa kuwononga kwambiri komanso chidwi.

Polyacrylamide (Pam), mzere wamadzi wosungunuka polymer, ndi gawo lofunikira kwambiri mu gawo lamadzi chifukwa cha kulemera kwamadzi, kusungunuka kwamadzi kwa kulemera kwa ma molecular.

Pam ndi zotumphuka zake zitha kugwiritsidwa ntchito ngati maluwa othandiza, ochepetsa ochepetsa, amagwiritsidwa ntchito kwambiri m'madzi, mafuta, miyala yamphongo, yomanga ndi magawo ena a mafakitale.

Munthadzi yapansi, madzi apamtunda ndi chimbudzi, zodetsa ndi zodetsa nthawi zambiri zimakhalapo monga tinthu tating'onoting'ono tokha kuti zikhazikike pansi pa mphamvu yokoka. Chifukwa kukhazikika kwachilengedwe kwalephera kukwaniritsa zofunikira, mothandizidwa ndi mankhwala kumapangitsa kutsiriza kwaukadaulo kwatha ntchito. Mwachitsanzo, Molekyulu amatenga pazinthu zingapo ndikupanga maluwa akulu, chifukwa chake, kukhazikika kwa tinthu kumayendetsedwa.

Poyerekeza ndi bokosi lolowera, Pam ali ndi zinthu zingapo zofunika: mitundu yambiri ya mikhalidwe yosiyanasiyana, yogwira ntchito kwambiri, mlingo wocheperako, osavuta kutumiza. Izi zimapangitsa kukhala nyumba yabwino kwambiri.

Ndi za kuchuluka kwa mankhwala a itorganic 1/30 mpaka 1/200.

Pam amagulitsidwa m'mitundu iwiri yayikulu: ufa ndi emulsion.

Pamporder Pam ndikosavuta kunyamula, koma osavuta kugwiritsa ntchito (zida zosungunuka ndizofunikira), pomwe emulsion siyosavuta kunyamula ndipo ili ndi moyo wamfupi.

Pam ali ndi zosungunukira kwambiri m'madzi, koma zimasungunuka pang'onopang'ono. Kusungunula kumawononga maola angapo kapena usiku. Kusakanikirana kwa makina kumathandizira kusungunula pam. Nthawi zonse muzichulukitsa Pam kuti musangalatse madzi - osati madzi ofunikira.

Kutenthetsa kumatha kuwonjezera kuchuluka kwa chilengedwe, koma kutentha sikuyenera kupitirira 60 ° C.

Pamphumwamba kwambiri ya polymer yankho la polymer ndi 0,5%, kuchuluka kwa magalimoto otsika kumatha kukonzedwa mu 1% kapena kupitilira pang'ono.

Kukonzekera Pam yankho kuyenera kugwiritsidwa ntchito masiku angapo, mwinanso kuyeserera kwa kukwera kumakhudzidwa.
