Polyacrylamide (PAM) Uye Kushandiswa Kwayo Mukurapa Kwemvura

Polyacrylamide (PAM) uye kushandiswa kwayo mukurapa kwemvura

Kudzora kusvibiswa kwemvura uye kutonga chikamu chakakosha chekuchengetedzwa kwezvakatipoteredza uye kuraswa kwemarara emvura kurapwa kuwana kubhadhara zvakanyanya uye zvakanyanya.

Polyacrylamide (PAM), mutsara wemvura inonyungudika polymer, ibasa rakakosha mumunda wekurapwa kwemvura nekuda kwehuremu hwemamorekuru, kunyungudika kwemvura, kudzorwa kwehuremu hwemamorekuru uye kwakasiyana mashandiro ekugadzirisa.

PAM uye zvigadzirwa zvayo zvinogona kushandiswa seanoshanda flocculants, thickening agent, dhiraivha yekudzikisa mumiririri, inoshandiswa zvakanyanya mukugadzirisa mvura, kugadzira mapepa, petroleum, marasha, geology, kuvaka uye mamwe maindasitiri.

Mumvura yepasi, pamusoro pemvura netsvina, tsvina netsvina zvinowanzovapo sezvimedu zvakawanda izvo zvidiki zvekusagadzikana pasi pesimba rinokwevera zvinhu pasi.Nekuda kwekuti sedimentation yechisikigo haina kukwanisa kuzadzisa zvinodiwa, nerubatsiro rwemakemikari kukurumidza kugadzirisa tekinoroji yakashandiswa mukugadzira.Semuyenzaniso, PAM molecule inobata pane akati wandei zvidimbu uye inogadzira yakakura floc, saka, kugadzirisa kwezvimedu kunokwidziridzwa.

Kuenzaniswa neiyo inorganic flocculant, PAM ine akati wandei akakosha mabhenefiti: akawanda akasiyana emamiriro akasiyana-siyana, kushanda kwepamusoro, kushomeka kwedosi, kushomeka kunogadzirwa, nyore mushure mekurapa.Izvi zvinoita kuti ive yakanyanya kunaka flocculant.

Icho chiri pamusoro peyero ye inorganic coagulant 1/30 kusvika 1/200.

PAM inotengeswa mumhando mbiri huru: poda uye emulsion.

Iyo poda PAM iri nyore kutakura, asi haisi nyore kushandisa (kuparara kwemidziyo inodiwa), nepo emulsion isiri nyore kutakura uye ine hupenyu hupfupi hwekuchengetedza.

PAM ine kunyungudika kukuru mumvura, asi inonyungudika zvishoma nezvishoma.Kuparara kunoda maawa akawanda kana usiku hwose.Kusanganiswa kwakanaka kwemagetsi kuchabatsira kuputsa PAM.Gara uchiwedzera zvishoma nezvishoma PAM kumvura yakamutswa - kwete mvura kuPAM.

Kupisa kunogona kuwedzera zvishoma kunyungudika, asi tembiricha haifanire kudarika 60°C.

Iyo yepamusoro PAM yekumisikidzwa kwepolymer mhinduro ndeye 0.5%, iyo yakadzika ma molecular PAM inogona kugadzirwa kuita 1% kana zvishoma yakakwira.

Yakagadzirirwa PAM mhinduro inofanirwa kushandiswa mumazuva akati wandei, zvikasadaro kuita kweflocculation kuchakanganiswa.
