Mayelana ne-Polyacrylamide

I-Polyacrylamide ibizwa nge-PAM, futhi ihlukaniswe i-anion (HPAM) kanye ne-cation (CPAM).I-Nonionic (NPAM) iyi-polymer eqondile futhi ingenye yezinhlobo ezisetshenziswa kakhulu kumakhompiyutha e-polymer ancibilika emanzini.Futhi okuphuma kuyo kungasetshenziswa njengama-flocculants asebenzayo, ama-thickeners, ama-ejenti okuqinisa amaphepha kanye nama-liquid drag reducers, njll, asetshenziswa kabanzi ekwelapheni kwamanzi, ukwenza amaphepha, uphethiloli, amalahle, izimayini kanye nokusansimbi, i-geology, izindwangu, ukwakhiwa, njll.

I-Polyacrylamide ibizwa ngokuthi No. 3 coagulant, flocculant No. 3;okubizwa nge-PAM;ngokuvamile ibizwa ngokuthi i-retention aid ekwenzeni iphepha nezinye izimboni.Njengamanje, imikhiqizo evame ukuhlinzekwa yinkampani yethu iqinile (impushana eyomile) kanye ne-emulsion.

I-Polyacrylamide ihlukaniswe yaba yi-anionic polyacrylamide;i-polyacrylamide ye-cationic;i-polyacrylamide ye-nonionic;i-zwitterionic polyacrylamide;Igama lesiNgisi;I-PAM (acrylamide).

Isimiso sesenzo

I-1) Umgomo we-flocculation: lapho i-PAM isetshenziselwa ukugeleza, ihlobene nezakhiwo ezingaphezulu zezinhlobo ezinyakazayo, ikakhulukazi amandla e-kinetic, i-viscosity, i-turbidity kanye nenani le-pH lokumiswa.Amandla ashukumisayo we-particle surface yisizathu sokuvinjelwa kwezinhlayiyana.I-PAM enezindleko eziphambene nendawo inganciphisa amandla e-kinetic kanye nokuhlanganisa.

2) I-Adsorption kanye ne-bridging: Amaketanga e-molecular e-PAM agxilile ezindaweni zezinhlayiya ezihlukene, futhi amabhuloho e-polymer akhiwa phakathi kwezinhlayiya, ukuze izinhlayiya zakhe ama-aggregate futhi zihlale.

3) I-Surface Adsorption: ukukhangisa okuhlukahlukene kwezinhlayiya zeqembu le-polar kuma-molecule e-PAM.

I-4) Ukuqinisa: Iketanga le-molecular ye-PAM kanye nesigaba esihlakazekile sihlanganisa isigaba esihlakazekile ndawonye ngemiphumela ehlukahlukene yemishini, ngokomzimba namakhemikhali ukuze kwakhiwe inethiwekhi.
