Fa'ailoga

Polyacrylamide o se polymer laina, o le oloa e masani ona vaevaeina i le paʻu mago ma colloidal lua fomu. E tusa ai ma lona mamafa molecular averesi, e mafai ona vaevaeina i le mamafa molecular maualalo (<1 miliona), mamafa molecular medium (2 ~ 4 miliona) ma le mamafa molecular maualuga (> .7 miliona). E tusa ai ma lona fausaga e mafai ona vaevaeina i non - ionic, anion ma cationic. Suavai malepe (HPAM) o ituaiga anion. O le filifili autu o le polyacrylamide o loʻo i ai se numera tele o vaega amide, faʻatasi ai ma le maualuga o vailaʻau, ma e mafai ona faʻaleleia e maua ai le tele o mea e maua mai i le polyacrylamide. O oloa ua faʻaaogaina lautele i le gaosiga o pepa, gaosiga o minerale, suauʻu suauʻu, metallurgy, mea faufale, togafiti otaota ma isi pisinisi. I le avea ai o se lubricant, suspension agent, omea stabilizer, suauʻu suauʻu sui, vai leiloa faʻaitiitia sui ma mafiafia sui, polyacrylamide ua faʻaaogaina lautele i le viliina, acidification, gau, vai plugging, sima, toe faaleleia suauu lona lua ma toe faaleleia suauu tulagalua.

Fa'atatauga

1. lomitusi ma vali vai lafoai

Lomitusi ma le valiina o vai otaota, nai lo fa'aleaganu'u mole mole maualalo, e fa'atatau i le tele fa'aleaganu'u masani o le coagulant, e maualuga le lelei o le coagulation, tulaga lelei ole ph e fa'apea: 8.0.

2. Fa'ata'otoga vai otaota pepa

Fa'ata'otoga vai otaota, lea e fa'aaogaina e pei o le coagulant nai lo le polyaluminum chloride, alumini sulfate, ma isi, e mafai fo'i ona fa'aaogaina e pei o le fa'amamaina o le fa'apalapala pepa.
