Polyacrylamide(PAM), sechinhu chakakosha chekurapa mvura, inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana dzeindasitiri. Zvisinei, kuputsa PAM kunogona kuva dambudziko kune vakawanda vashandisi. PAM zvigadzirwa zvinoshandiswa mumvura inoraswa mumaindasitiri zvinonyanya kuuya nenzira mbiri: hupfu hwakaoma uye emulsion. Ichi chinyorwa chichasuma nzira yekumisa yemhando mbiri dzePAM zvakadzama kuti ive nechokwadi chekuti vashandisi vanowana mibairo yakanaka mukushanda chaiko.
Iyo yakananga dissolution nzira ndiyo yakapfava uye yakajairika PAM dissolution nzira. Iyi nzira yakakodzera PAM poda ine yakaderera molecular uremu uye iri nyore kunyungudika. Heano matanho chaiwo:
Gadzirira Mugaba: Sarudza chigadziko chepurasitiki chakachena, chakaoma, chinogara chakakura zvakakwana kubata PAM poda nemvura. Usashandise midziyo yesimbi kana midziyo ine mavara esimbi.
Wedzera Solvent: Wedzera huwandu hwakakodzera hwemvura.
Kubvongodza: Tanga kubvongodza. Paunenge uchikuchidzira, iva nechokwadi chokuti chinokuchidzira chanyura zvachose mumushonga kuti usapupure. Iyo inomhanyisa kumhanya haifanirwe kunge yakakwira zvakanyanya kuti udzivise kuputsika kwePAM molecular chain.
Wedzera PAM Powder: Zvishoma nezvishoma wedzera inodiwa PAM poda mumudziyo uchikurudzira zvinyoro-nyoro kudzivirira guruva rinobhururuka. Ramba uchikurudzira mhinduro kuti uite PAM poda yakaenzana yakapararira mumushonga.
Mirira Kuparara: Ramba uchikurudzira uye cherechedza kuparara kwePAM powder. Kazhinji, inoda kukurudzirwa kwemaawa 1 kusvika ku2 kusvikira PAM powder yapera zvachose.
Tarisa Solubility: Mushure mekupedza kunyungudika, tarisa kuti yakanyungudika zvachose nekutarisa pachena kana refractive index yemhinduro. Kana pane zvimedu zvisina kunyunguduka kana zvimedu zvikabuda, ramba uchikurunga kusvika zvanyungudika zvachose. Kana molecular huremu hwePAM hwakanyanya uye kupera kwacho kunonoka, inogonawo kupisa zvakakodzera, asi haifaniri kudarika 60 ° C.
Gadzirira Container uye Zvishandiso: Sarudza mudziyo wakakura zvakakwana kuti uone kuti pane nzvimbo yakakwana yekusanganisa. Iva nechibatiso kana tsvimbo yakagadzirira kuti uone kuti mhinduro yacho inosanganiswa zvakakwana.
Gadzirira Mushonga: Wedzera mvura uye PAM emulsion panguva imwe chete, uye tanga mutsara panguva imwe chete kuti uone kuti emulsion nemvura zvakanyatsosanganiswa.
Dzora Iyo yekupedzisira Concentration: Iyo yekupedzisira yekumisikidzwa kwePAM emulsion inofanirwa kudzorwa pa1-5% kuve nechokwadi cheyakanakisa flocculation effect. Kana iwe uchida kugadzirisa kugadzirisa, ramba uchiwedzera mvura kana kuwedzera PAM emulsion.
Ramba Uchikurudzira: Mushure mekuwedzera emulsion yePAM, ramba uchikurudzira mhinduro ye15-25 maminitsi. Izvi zvinobatsira PAM mamorekuru kupararira nekunyungudika, kuve nechokwadi chekugovera kwavo mumvura.
Dzivisa Kuwedzeredza Kukurudzira: Kunyangwe kubvongodza kwakakodzera kunobatsira kunyungudutsa PAM, kubvongodza zvakanyanya kunogona kukonzera kuderedzwa kwemamorekuru ePAM, kudzikisa flocculation yayo. Naizvozvo, dzora kumhanya uye nguva.
Kuchengeta uye Kushandisa: Chengetedza yakanyungudika PAM mhinduro munzvimbo ine rima, yakaoma, kuve nechokwadi chekuti tembiricha yakakodzera. Dzivisa chiedza chezuva kuti udzivise kuparara kwePAM. Paunenge uchishandisa, iva nechokwadi chekufanana kwemhinduro kudzivirira kukanganisa iyo flocculation mhedzisiro nekuda kwekusaenzana kugovera.
