Ko te Polyacrylamide e kiia ana ko PAM, ka wehea ki te anion (HPAM) me te cation (CPAM).Ko te Nonionic (NPAM) he polymer ahorangi me tetahi o nga momo tino whakamahia i roto i nga pūhui polymer wairewa-wai.A ka taea te whakamahi i ona pärönaki hei flocculants whai hua, thickeners, āpiha whakakaha pepa me te whakaiti tō wai, me ētahi atu, whakamahia whānuitia i roto i te maimoatanga wai, pepa, hinu, waro, keri me te metallurgy, geology, pueru, hanga, etc.
Ko te polyacrylamide e kiia ana ko te nama 3 coagulant, flocculant Nama 3;ka kiia ko PAM;he maha nga wa e kiia ana he awhina pupuri i roto i te mahi pepa me etahi atu ahumahi.I tenei wa, ko nga hua e tukuna mai ana e to taatau kamupene he totoka (paura maroke) me te whakaehunga.
Kua wehea te polyacrylamide ki te polyacrylamide anionic;polyacrylamide cationic;polyacrylamide nonionic;zwitterionic polyacrylamide;Ingoa Ingarihi;PAM (acrylamide).
Te kaupapa o te mahi
1) Ko te kaupapa o te pupuhi: i te wa e whakamahia ana te PAM mo te pupuhi, e pa ana ki nga ahuatanga o te mata o nga momo pupuhi, ina koa ko te kaha o te kinetic, te viscosity, te turbidity me te uara pH o te whakatārewatanga.Ko te kaha hihiri o te mata matūriki te take mo te aukati matūriki.Ko te PAM me nga utu rereke o te mata ka taea te whakaiti i te kaha o te hiko me te whakahiato.
2) Adsorption and bridging: PAM molecular chains are fixed on the surfaces of different particles, and polymer bridges are made between the particles, so that the particles form aggregates and settle.
3) Te urunga o te mata: nga momo whakaurunga o nga matūriki roopu polar i runga i nga ngota ngota PAM.
4) Whakakaha: Ko te mekameka ngota ngota PAM me te wahanga marara e whakawhanaunga ana i te wahanga marara ma roto i nga momo paanga miihini, tinana me te matū hei hanga whatunga.
