Polyacrylamideyog dav lees paub rau nws cov txiaj ntsig hauv flocculation, txheej txheem tseem ceeb hauv ntau yam lag luam xws li kev kho dej khib nyiab, mining, thiab papermaking.Cov khoom siv hluavtaws no, tsim los ntawm acrylamide monomers, muaj cov yam ntxwv tshwj xeeb uas ua rau nws tshwj xeeb zoo rau kev siv flocculation.
Ua ntej thiab qhov tseem ceeb tshaj plaws, qhov hnyav molecular ntawm polyacrylamide yog qhov tseem ceeb ua rau nws muaj peev xwm flocculation tshwj xeeb.Cov chains ntev ntawm kev rov ua dua acrylamide units tso cai rau kev sib cuam tshuam nrog cov khoom raug tshem tawm hauv kev daws teeb meem.Cov qauv molecular no txhim kho cov polymer lub peev xwm los tsim cov flocs loj thiab ruaj khov, uas yog cov sib sau ua ke ntawm cov khoom zoo.Yog li ntawd, polyacrylamide tuaj yeem khi ua ke cov khoom me me, ua kom yooj yim rau lawv sai sai los yog sib cais los ntawm cov kua theem.
Cov dej-soluble xwm ntawm polyacrylamide ntxiv txhim khu nws flocculation kev ua tau zoo.Ua nyob rau hauv dej, polyacrylamide tuaj yeem yooj yim dispersed thiab tov rau hauv ib qho kev daws teeb meem, kom ntseeg tau tias muaj kev sib faib thoob plaws hauv lub cev.Cov yam ntxwv no yog qhov tseem ceeb rau kev ua tiav zoo sib xws thiab muaj txiaj ntsig flocculation, vim tias cov polymer xav tau los rau hauv kev sib cuag nrog tag nrho cov khoom hauv kev daws teeb meem los tsim flocs.
Polyacrylamide tus nqi nruab nrab yog lwm qhov tseem ceeb uas ua rau nws cov flocculation efficiency.Lub polymer feem ntau tsis yog-ionic, txhais tau tias nws tsis muaj cov nqi hluav taws xob.Qhov nruab nrab no tso cai rau polyacrylamide cuam tshuam nrog ntau yam ntawm cov khoom, tsis hais lawv cov nqi saum npoo.Nyob rau hauv sib piv, anionic los yog cationic polymers tej zaum yuav xaiv nyob rau hauv lawv flocculation zog, txwv lawv muaj feem xyuam rau tej yam hais.Polyacrylamide tus nqi nruab nrab ua rau nws muaj ntau yam thiab haum rau ntau yam kev kho dej.
Tsis tas li ntawd, kev tswj hwm hydrolysis ntawm polyacrylamide tuaj yeem qhia cov pab pawg anionic, ntxiv dag zog rau nws txoj kev ua haujlwm flocculation.Los ntawm kev hloov kho cov yam ntxwv ntawm cov khoom siv polymer, nws ua haujlwm zoo dua rau kev nyiam thiab nruab nrab cov khoom nrog cov nqi sib txawv.Qhov no versatility nyob rau hauv tus nqi manipulation tso cai rau polyacrylamide hloov mus rau txawv dej compositions thiab tailor nws flocculation peev xwm raws li.
Qhov yooj ntawm polyacrylamide nyob rau hauv cov nqe lus ntawm nws lub cev daim ntawv kuj pab txhawb rau nws cov kev ua tau zoo nyob rau hauv flocculation txheej txheem.Nws muaj nyob rau hauv ntau hom xws li emulsions, hmoov, thiab gels.Qhov kev sib txawv no ua rau cov neeg siv xaiv cov ntawv tsim nyog tshaj plaws raws li cov cai tshwj xeeb ntawm lawv daim ntawv thov.Piv txwv li, emulsions feem ntau nyiam rau kev yooj yim ntawm kev tuav, thaum hmoov muab kev yooj yim hauv kev cia thiab kev thauj mus los.
Hauv kev xaus, polyacrylamide qhov tshwj xeeb flocculation kev ua tau zoo yog vim nws qhov hnyav molecular, dej solubility, nqi nruab nrab, ntau yam hauv kev tswj hwm, thiab hloov pauv hauv lub cev.Cov khoom no sib sau ua ke ua polyacrylamide ua tau zoo thiab muaj ntau yam polymer hauv kev tsim cov flocs ruaj khov, yog li pab hauv kev sib cais thiab tshem tawm cov khoom tshem tawm los ntawm cov kua hauv ntau cov txheej txheem.
