Ngikhetha kanjani uhlobo lwePolyacrylamide?

I-Polyacrylamide(PAM) ngokuvamile ingahlukaniswa ibe i-anionic, i-cationic, ne-nonionic ngokohlobo lwe-ion. Isetshenziselwa ikakhulukazi i-flocculation ekwelapheni amanzi. Lapho ukhetha, izinhlobo ezahlukene zamanzi angcolile zingakhetha izinhlobo ezahlukene. Udinga ukukhetha i-PAM efanele ngokuya ngezimpawu zendle yakho. Ngesikhathi esifanayo, kufanele futhi ucacise ukuthi iyiphi inqubo i-polyacrylamide ezongezwa ngayo kanye nenjongo ofuna ukuyifinyelela ngokuyisebenzisa.

Izinkomba zobuchwepheshe ze-polyacrylamide ngokuvamile zifaka isisindo samangqamuzana, idigri ye-hydrolysis, ionicity, i-viscosity, okuqukethwe okusele kwe-monomer, njll. Lezi zinkomba kufanele zicaciswe ngokuvumelana namanzi angcolile owelaphayo.

1. Isisindo samangqamuzana/i-viscosity

I-Polyacrylamide inezinhlobonhlobo zezisindo zamangqamuzana, ukusuka kokuphansi kuye phezulu kakhulu. Isisindo samangqamuzana sithinta ukusebenza kwama-polymers ezinhlelweni ezahlukene. I-polyacrylamide enesisindo esikhulu samangqamuzana ivamise ukusebenza ngempumelelo kakhulu enqubweni ye-flocculation ngoba amaketanga e-polymer awo made futhi angaxhuma izinhlayiya eziningi ndawonye.

I-viscosity yesisombululo se-PAM iphezulu kakhulu. Uma i-ionization izinzile, isisindo samangqamuzana esikhulu se-polyacrylamide, i-viscosity enkulu yesisombululo sayo. Lokhu kungenxa yokuthi uchungechunge lwama-macromolecular lwe-polyacrylamide lude futhi luncane, futhi ukumelana nokunyakaza kwisixazululo kukhulu kakhulu.

2. Izinga le-hydrolysis kanye ne-ionicity

I-ionicity ye-PAM inethonya elikhulu ekusetshenzisweni kwayo, kepha inani layo elifanelekile lincike ohlotsheni kanye nemvelo yezinto ezilashwayo, futhi kunamanani ahlukile afanelekile ezimeni ezahlukahlukene. Uma amandla e-ionic wento ephathwayo ephakeme (izinto ezingaphili), i-ionicity ye-PAM esetshenzisiwe kufanele ibe phezulu, ngaphandle kwalokho kufanele ibe ngaphansi. Ngokuvamile, idigri ye-anion ibizwa ngokuthi idigri ye-hydrolysis, futhi izinga le-ion ngokuvamile libizwa ngokuthi izinga le-cation.

Indlela yokukhetha i-polyacrylamidekuncike ekugxilweni kwama-colloid kanye nezinto eziqinile ezimisiwe emanzini. Ngemuva kokuqonda izinkomba ezingenhla, ungakhetha kanjani i-PAM efanelekile?

1. Qonda umthombo wendle

Okokuqala, kufanele siqonde umthombo, imvelo, ukwakheka, okuqukethwe okuqinile, njll.

Ngokuvamile, i-cationic polyacrylamide isetshenziselwa ukwelapha udaka oluphilayo, kanti i-anionic polyacrylamide isetshenziselwa ukwelapha udaka lwezinto ezingaphili. Uma i-pH iphezulu, i-cationic polyacrylamide akufanele isetshenziswe, futhi uma i-anionic polyacrylamide akufanele isetshenziswe. I-acidity enamandla ikwenza kungafaneleki ukusebenzisa i-anionic polyacrylamide. Uma okuqukethwe okuqinile kwe-sludge kuphezulu, inani le-polyacrylamide elisetshenzisiwe likhulu.

2. Ukukhethwa kwe-iocity

Ukuze uthole udaka oludinga ukuphelelwa amanzi emzimbeni ekwelapheni indle, ungakhetha flocculants nge ionicity ezahlukene ngokusebenzisa ucwaningo encane ukuze ukhethe polyacrylamide ezifanele kakhulu, okungase kuzuzwe best flocculation umphumela futhi unciphise umthamo, ukonga izindleko.

3. Ukukhethwa kwesisindo samangqamuzana

Ngokuvamile, ukuphakama kwesisindo samangqamuzana semikhiqizo ye-polyacrylamide, i-viscosity enkulu, kodwa uma isetshenziswa, isisindo samangqamuzana somkhiqizo siphezulu, ngcono umphumela wokusetshenziswa. Ekusetshenzisweni okuqondile, isisindo esifanele samangqamuzana e-polyacrylamide kufanele sinqunywe ngokusho kwemboni yesicelo sangempela, izinga lamanzi kanye nemishini yokwelapha.

Uma uthenga futhi usebenzisa i-PAM okokuqala, kunconywa ukuthi unikeze isimo esithile sokuthuthwa kwendle kumkhiqizi we-flocculant, futhi sizokuncoma uhlobo lomkhiqizo olufaneleka kakhulu kuwe. Futhi amasampula e-mail ukuze ahlolwe. Uma unolwazi oluningi ekuhlanzeni kwakho indle, ungasitshela izidingo zakho ezithile, izinkambu zokufaka isicelo, nezinqubo, noma usinike ngokuqondile amasampula e-PAM owasebenzisayo njengamanje, futhi sizokufanisa ne-polyacrylamide efanele.
