Polyacrylamide waxaa loo tixraacaa PAM, waxaana loo qaybiyaa anion (HPAM) iyo cation (CPAM).Nonionic (NPAM) waa polymer toosan iyo mid ka mid ah noocyada aadka loo isticmaalo ee xeryahooda polymer-ka ee biyaha ku milma.Oo ay derivatives waxaa loo isticmaali karaa sida flocculants wax ku ool ah, dhumuc weyn, wakiilada xoojinta waraaqaha iyo dareeraha jiidaya reducers, iwm, si ballaaran loo isticmaalo daaweynta biyaha, waraaqaha, batroolka, dhuxusha, macdanta iyo biraha, geology, dunta, dhismaha, iwm qaybta warshadaha.
Polyacrylamide waxaa lagu magacaabaa No. 3 coagulant, flocculant No. 3;loo yaqaan PAM;waxaa inta badan loogu yeeraa gargaarka xajinta ee waraaqaha iyo warshadaha kale.Waqtigan xaadirka ah, alaabta sida caadiga ah ay keento shirkadeena waa adag (budo qalalan) iyo emulsion.
Polyacrylamide wuxuu u qaybsan yahay polyacrylamide anionic;polyacrylamide cationic;polyacrylamide nonionic;polyacrylamide zwitterionic;Magaca Ingiriisiga;PAM (acrylamide).
Mabda'a ficilka
1) Mabda'a flocculation: marka PAM loo isticmaalo flocculation, waxay la xiriirtaa sifooyinka dusha sare ee noocyada flocculated, gaar ahaan awoodda kinetic, viscosity, turbidity iyo qiimaha pH ee joojinta.Awoodda firfircoon ee dusha sare ee walxaha ayaa ah sababta xannibaadda walxaha.PAM oo leh kharashyo dusha ka soo horjeeda ayaa yarayn kara awoodda dhaqdhaqaaqa iyo isku geynta.
2) Isku-xidhka iyo isku-xidhka: silsiladaha molecular PAM ayaa lagu dhejiyaa dusha sare ee qaybo kala duwan, iyo buundooyinka polymer ayaa ka dhex sameysma qaybaha, si ay qaybuhu u sameeyaan isku-dar ah oo ay degaan.
3) Adsorption dusha sare: xayeysiisyo kala duwan oo ah qaybaha kooxda dabaysha ee ku jira molecules PAM.
4) Xoojinta: Silsiladda molecular PAM iyo wejiga la kala firdhiyey waxay si wada jir ah u saameeyaan wejiga kala firdhiyey iyada oo loo marayo noocyo kala duwan oo farsamo, jireed iyo kiimikooyin si loo sameeyo shabakad.
