Polyacrylamide(PAM), semushonga unokosha wekuchenesa mvura, unoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana. Zvisinei, kunyungudutsa PAM kunogona kuva dambudziko kune vashandisi vazhinji. Zvigadzirwa zvePAM zvinoshandiswa mumvura yakasviba yeindasitiri zvinonyanya kuuya mumhando mbiri: hupfu hwakaoma uye emulsion. Chinyorwa chino chichatsanangura nzira yekunyungudutsa yemhando mbiri dzePAM zvakadzama kuitira kuti vashandisi vawane mhedzisiro yakanaka mukushanda chaiko.
Nzira yekunyungudutsa zvakananga ndiyo nzira iri nyore uye inonyanya kushandiswa yekunyungudutsa PAM. Nzira iyi yakakodzera upfu hwePAM hune huremu hwakaderera uye huri nyore kunyungudutsa. Heano matanho chaiwo:
Gadzirira Chirongo: Sarudza chigadziko chepurasitiki chakachena, chakaoma, uye chakasimba chakakura zvakakwana kutakura upfu hwePAM nemvura zvinodiwa. Usashandise midziyo yesimbi kana midziyo ine mavara esimbi.
Wedzerai solvent: Wedzerai huwandu hwakakodzera hwemvura.
Kukurunga: Tanga kukurunga. Paunenge uchikurunga, iva nechokwadi chekuti kukurunga kwanyura zvachose mumushonga kudzivirira mabubbles. Kumhanya kwekukurunga hakufanirwe kunge kwakanyanya kudzivirira kutyoka kwecheni yemamorekuru ePAM.
Wedzera PAM Powder: Isa zvishoma nezvishoma PAM powder inodiwa mumudziyo uchikurunga zvinyoro nyoro kuti guruva risabhururuke. Ramba uchikurunga mushonga kuti PAM powder iparadzirwe zvakaenzana mumusanganiswa.
Mirira Kunyungudika: Ramba uchikurunga uye tarisa kunyungudika kweupfu hwePAM. Kazhinji, hunoda kukurunga kweawa imwe kusvika maviri kusvika upfu hwePAM hwanyungudika zvachose.
Tarisa Kunyungudika: Mushure mekupedza kunyungudika, tarisa kana yanyungudika zvachose nekutarisa kujeka kana kuti refractive index yemushonga. Kana paine zvidimbu zvisina kunyungudika kana maburi akaonekwa, ramba uchikurunga kusvika yanyungudika zvachose. Kana huremu hwePAM hwakanyanya uye kunyungudika kwacho kuchinonoka, kunogonawo kupiswa zvakakodzera, asi hakufanirwe kudarika 60°C.
Gadzirirai Chirongo Nezvishandiso: Sarudzai chirongo chakakura zvakakwana kuti muve nechokwadi chekuti pane nzvimbo yakakwana yekusanganisa. Iva nechinosanganisa kana chimuti chakagadzirira kuti musanganiswa usanganiswe zvakanaka.
Gadzirira Mhinduro: Wedzera mvura nePAM emulsion panguva imwe chete, wotanga stirrer panguva imwe chete kuti uve nechokwadi chekuti emulsion nemvura zvanyatsosanganiswa.
Dzora Kuwanda Kwemvura: Kuwanda kwemvura yePAM kunofanira kudzorwa pa1-5% kuti pave nemhedzisiro yakanaka ye flocculation. Kana uchida kugadzirisa kuwanda kwemvura, ramba uchiwedzera mvura kana kuwedzera PAM emulsion.
Ramba Uchikurunga: Mushure mekuwedzera PAM emulsion, ramba uchikurunga kwemaminetsi gumi nemashanu kusvika makumi maviri nemashanu. Izvi zvinobatsira mamorekuru ePAM kupararira nekunyungudika zvizere, zvichiita kuti akwanise kupararira mumvura zvakaenzana.
Dzivisa Kukurunga Zvakawandisa: Kunyangwe kukurunga kwakakodzera kuchibatsira kunyungudutsa PAM, kukurunga kwakanyanya kunogona kukonzera kuparara kwemamorekuru ePAM, zvichideredza simba rayo rekukwesha. Saka, dzora kumhanya kwenguva yekukurunga.
Kuchengeta uye Kushandisa: Chengeta mushonga wePAM wakanyungudutswa munzvimbo ine rima, yakaoma, uchiita kuti tembiricha ikwane. Dzivisa chiedza chezuva chakananga kudzivirira kuparara kwePAM. Paunenge uchishandisa, iva nechokwadi chekuti mushonga wacho wakafanana kuti usakanganisa kuyerera kwemvura nekuda kwekupararira kusina kuenzana.
