ʻO ka pauka keʻokeʻo a i ʻole granule, a hiki ke māhele ʻia i ʻehā mau ʻano: non-ionic, anionic, cationic a me Zwitterionic. ʻO ka Polyacrylamide (PAM) kahi inoa maʻamau o nā homopolymers o ka acrylamide a i ʻole copolymerized me nā monomers ʻē aʻe. ʻO ia kekahi o nā polymers hiki ke hoʻohana nui ʻia i ka wai. Hoʻohana nui ʻia ia i ka hoʻohana ʻana i ka aila, ka mālama ʻana i ka wai, ka textile, ka hana pepa, ka hana mineral, ka lāʻau lapaʻau, ka mahiʻai a me nā ʻoihana ʻē aʻe. ʻO nā kahua noi nui ma nā ʻāina ʻē he mālama wai, hana pepa, mining, metallurgy, etc.; I kēia manawa, ʻo ka ʻai nui loa o ka PAM no ka māla hana ʻaila ma Kina, a ʻo ka ulu wikiwiki ʻana no ka māla wai a me ka māla pepa.
