Polyacrylamideinozivikanwa zvikuru nekushanda kwayo zvakanaka mukugadzira mapuranga, chinhu chakakosha mumaindasitiri akasiyana-siyana akadai sekuchenesa mvura yakasviba, kugadzira migodhi, uye kugadzira mapepa. Iyi polymer yakagadzirwa, inoumbwa neacrylamide monomers, ine hunhu hwakasiyana hunoita kuti ive yakakodzera kushandiswa mukugadzira mapuranga.
Chekutanga uye chakakosha ndechekuti huremu hwakawanda hwemamorekuru epolyacrylamide chinhu chakakosha chinobatsira pakugona kwayo kutenderera. Maketani marefu ezvikamu zveacrylamide zvinodzokororwa anobvumira kudyidzana kwakakura nezvidimbu zvakasungirirwa mumushonga. Maumbirwo aya emamorekuru anowedzera kugona kwepolymer kugadzira mafloc makuru uye akagadzikana, ayo ari maunganidzwa ezvidimbu zvidiki. Nekuda kweizvozvo, polyacrylamide inogona kubatanidza pamwe chete zvidimbu zvidiki zvinobudirira, zvichiita kuti zvikwanise kugadzikana kana kuparadzaniswa nekukurumidza kubva pachikamu chemvura.
Kunyungudika kwepolyacrylamide mumvura kunowedzera kushanda kwayo mukunyungudika. Sezvo ichinyungudika mumvura, polyacrylamide inogona kupararira nyore nyore uye kusanganiswa kuita mhinduro, zvichiita kuti ive nechokwadi chekupararira kwakafanana muhurongwa hwese. Hunhu uhwu hwakakosha kuti pave nekunyungudika kwakafanana uye kunobudirira, sezvo polymer ichida kusangana nezvidimbu zvese zviri mumushonga kuti igadzire maflocs.
Kusapindirana kwePolyacrylamide pakuchaja chimwe chinhu chakakosha chinobatsira mukushanda kwayo zvakanaka kweflocculation. Iyo polymer kazhinji haina ionic, zvichireva kuti haina net electrical charge. Kusapindirana uku kunobvumira polyacrylamide kuti ishande nezvikamu zvakasiyana-siyana, zvisinei nekuti pamusoro pechaja yavo yakadini. Kusiyana neizvi, mapolymer eanionic kana cationic anogona kusarudza muhunhu hwavo hweflocculation, zvichideredza kushanda kwavo kumarudzi chaiwo ezvikamu. Kusapindirana kwePolyacrylamide pakuchaja kunoita kuti ishande zvakasiyana-siyana uye yakakodzera mamiriro akasiyana-siyana ekurapa mvura.
Uyezve, hydrolysis inodzorwa yepolyacrylamide inogona kuunza mapoka eanionic, zvichiwedzera kushanda kwayo mukutenderera. Nekugadzirisa hunhu hwepolymer hwekudzvanya, inova inoshanda zvakanyanya mukukwezva nekuderedza zvidimbu zvine machaji akasiyana. Kuchinja uku mukuchinja kwechaji kunobvumira polyacrylamide kuti igadzirise magadzirirwo akasiyana emvura uye kugadzirisa kugona kwayo kutenderera zvinoenderana.
Kuchinjika kwepolyacrylamide maererano nechimiro chayo chemuviri kunobatsirawo mukushanda kwayo mukuita kweflocculation. Inowanikwa mumhando dzakasiyana-siyana dzakadai seemulsions, powders, uye gels. Kusiyana uku kunoita kuti vashandisi vasarudze chimiro chakakodzera zvichienderana nezvinodiwa zvekushandisa kwavo. Semuenzaniso, emulsions dzinowanzo shandiswa kuti zvive nyore kubata, nepo powders dzichiita kuti zvive nyore kuchengetedza nekutakura.
Mukupedzisa, kushanda kwepolyacrylamide zvakanaka kwazvo kunokonzerwa nehuremu hwayo hwakawanda hwemamorekuru, kunyungudika kwemvura, kusapindirana kwechaja, kushanduka-shanduka mukushandiswa kwechaja, uye kuchinjika muchimiro chemuviri. Hunhu uhwu pamwe chete hunoita kuti polyacrylamide ive polymer inoshanda zvikuru uye inochinjika mukuita kuti pave nemaflocs akagadzikana, nokudaro ichibatsira mukupatsanurwa nekubvisa zvidimbu zvakamiswa kubva mumhinduro dzemvura mumabasa akasiyana-siyana emaindasitiri.
