Polyacrylamide inonzi PAM, uye yakakamurwa kuita anion (HPAM) uye cation (CPAM).Nonionic (NPAM) mutsara wepolymer uye imwe yemhando dzinoshandiswa zvakanyanya mumvura-inonyungudika polymer makomisheni.Uye derivatives ayo anogona kushandiswa zvinobudirira flocculants, thickeners, bepa kusimbisa vamiririri uye mvura achizvuzvurudza reducers, etc., zvikuru kushandiswa pakurapa mvura, papermaking, peturu, marasha, migodhi uye simbi, geology, machira, kuvaka, etc. Industrial sector.
Polyacrylamide inonzi No. 3 coagulant, flocculant Nha. 3;inonzi PAM;inowanzonzi rubatsiro rwekuchengetedza mukugadzira mapepa nemamwe maindasitiri.Parizvino, zvigadzirwa zvinowanzo kupihwa nekambani yedu yakasimba (yakaoma hupfu) uye emulsion.
Polyacrylamide yakakamurwa kuva anionic polyacrylamide;cationic polyacrylamide;nonionic polyacrylamide;zwitterionic polyacrylamide;English name;PAM (acrylamide).
Nheyo yechiito
1) Nheyo yekuyerera: kana PAM inoshandiswa pakubhururuka, inobatana nepamusoro pezvinhu zvemhando dzakatenderedzwa, kunyanya iyo kinetic inogona, viscosity, turbidity uye pH kukosha kwekumiswa.Iko kusimba kwekugona kwechikamu chepamusoro ndicho chikonzero chekudzivirira kwechidimbu.PAM ine yakatarisana pamusoro pechaji inogona kuderedza iyo kinetic mukana uye akaunganidzwa.
2) Adsorption uye bridging: PAM molecular cheni dzakagadziriswa panzvimbo dzezvikamu zvakasiyana, uye mabhiriji epolymer anoumbwa pakati pezvimedu, kuitira kuti zvimedu zvigadzire zvikamu uye zvigadzikane.
3) Surface adsorption: akasiyana adsorptions epolar boka zvidimbu paPAM mamorekuru.
4) Kusimbisa: Iyo PAM molecular chain uye chikamu chakapararira chinobatanidza chikamu chakapararira pamwe chete kuburikidza neakasiyana ma mechanika, emuviri uye emakemikari mhedzisiro kugadzira network.
