Ua kapa ʻia ʻo Polyacrylamide he PAM, a ua māhele ʻia i ka anion (HPAM) a me ka cation (CPAM).ʻO ka Nonionic (NPAM) he polymer linear a ʻo kekahi o nā ʻano mea i hoʻohana nui ʻia i loko o nā pūhui polymer wai.A me kona derivatives hiki ke hoʻohana 'ia e like me flocculants pono, thickeners, pepa hooikaika 'oihana a me ka wai huki reducers, etc., hoʻohana nui 'ia i ka wai lapaʻau, papermaking, aila, lanahu, mining a me metallurgy, geology, textiles, kūkulu, etc.
Kapaʻia ka polyacrylamide No. 3 coagulant, flocculant No. 3;i kapa ʻia ʻo PAM;ua kapa pinepine ʻia he kōkua paʻa i ka hana pepa a me nā ʻoihana ʻē aʻe.I kēia manawa, ʻo nā huahana i hoʻolako pinepine ʻia e kā mākou hui he paʻa (ka pauka maloʻo) a me ka emulsion.
Hoʻokaʻawale ʻia ka polyacrylamide i anionic polyacrylamide;cationic polyacrylamide;polyacrylamide nonionic;zwitterionic polyacrylamide;inoa Pelekane;PAM (acrylamide).
Kumu o ka hana
1) ʻO ke kumu o ka flocculation: ke hoʻohana ʻia ʻo PAM no ka flocculation, pili ia i nā ʻano o ka ʻili o nā ʻano flocculated, ʻoi aku ka nui o ke kinetic hiki, viscosity, turbidity a me ka waiwai pH o ka hoʻokuʻu.ʻO ka mana ikaika o ka ʻili o ka ʻili ke kumu o ka pale ʻana i ka ʻāpana.Hiki i ka PAM me nā kumukūʻai kūʻē ke hōʻemi i ka mana kinetic a me ka hui.
2) Adsorption and bridging: Hoʻopaʻa ʻia nā kaulahao mole PAM ma nā ʻili o nā ʻāpana like ʻole, a ua hoʻokumu ʻia nā alahaka polymer ma waena o nā ʻāpana, i mea e hoʻohui ai nā ʻāpana a noho.
3) Ka hoʻopili ʻana o ka ʻili: nā adsorption like ʻole o nā ʻāpana hui polar ma nā molekala PAM.
4) Hoʻoikaika: ʻO ke kaulahao mole PAM a me ka māhele i hoʻopuehu ʻia e hoʻopili i ka māhele i hoʻopuehu pū ʻia ma o nā hopena mechanical, kino a me ke kemika e hana i kahi pūnaewele.
