E uiga i le Polyacrylamide

O le Polyacrylamide ua taʻua o le PAM, ma ua vaevaeina i le anion (HPAM) ma le cation (CPAM).Nonionic (NPAM) o se polymer laina ma o se tasi o ituaiga sili ona faʻaaogaina i totonu o le vai-soluble polymer compounds.Ma e mafai ona faʻaaogaina ana mea faʻapitoa e pei o flocculants aoga, mafiafia, pepa faʻamalosi pepa ma vai faʻaitiitia toso, ma isi, faʻaaogaina lautele i le vai, faʻapipiʻi pepa, suauu, koale, mining ma metallurgy, geology, textiles, fau, ma isi vaega o alamanuia.

Polyacrylamide e taʻua Numera 3 coagulant, flocculant Numera 3;ta'ua o le PAM;e masani ona taʻua o le taofiga fesoasoani i le gaosiga o pepa ma isi pisinisi.I le taimi nei, o oloa e masani ona tuʻuina mai e la matou kamupani o le malo (paʻu mago) ma le emulsion.

Polyacrylamide ua vaevaeina i anionic polyacrylamide;cationic polyacrylamide;polyacrylamide e le ninionic;zwitterionic polyacrylamide;igoa Igilisi;PAM (acrylamide).

Mataupu Faavae o le faatinoga

1) Le mataupu faavae o le flocculation: pe a faʻaaogaina le PAM mo le faʻafefeteina, e fesoʻotaʻi ma mea o loʻo i luga ole laiga o meaola, aemaise lava le malosi o le kinetic, viscosity, turbidity ma le pH o le faʻamalolo.O le malosi malosi o le vaega o le vaega o le mafuaʻaga lea o le faʻalavelave faʻapitoa.O le PAM fa'atasi ai ma tau fa'afeagai i luga ole laiga e mafai ona fa'aitiitia ai le malosi ole kinetic ma fa'aputuga.

2) Adsorption and bridging: O filifili mole mole PAM o loʻo faʻapipiʻiina i luga o luga o mea eseese, ma faʻapipiʻi alalaupapa polymer i le va o vaega, ina ia faʻapipiʻi faʻatasi ma faʻamautu.

3) Faʻasalaga i luga ole laiga: faʻasalalauga eseese o vaega vaega polar i luga ole molelaʻau PAM.

4) Faʻamalosia: O le filifili mole mole PAM ma le vaega faʻasalalau e aʻafia ai le vaega faʻasalalau faʻatasi e ala i aʻafiaga eseese faʻainisinia, faaletino ma vailaʻau e fausia ai se fesoʻotaʻiga.
