Ungayengeza kanjani i-PAM

I-Polyacrylamide (PAM) iyi-polymer eqondile ene-flocculation, ukunamathela, ukunciphisa ukuhudula, nezinye izakhiwo. NjengoI-Polymer Organic Flocculant, isetshenziswa kabanzi emkhakheni wokwelapha amanzi. Uma usebenzisa i-PAM, izindlela zokusebenza ezifanele kufanele zilandelwe ukuze kugwenywe ukumoshakala kwamakhemikhali.

Inqubo Yokwengeza i-PAM

NgobaI-PAM eqinile, idinga ukungezwa emanzini ngemva kokuncibilika. Ukuze uthole izimfanelo ezahlukene zamanzi, izinhlobo ezihlukahlukene ze-PAM zidinga ukukhethwa, futhi izixazululo zihlukaniswe zibe ukugxila okuhlukene. Lapho ungeza i-polyacrylamide, kufanele kuqashelwe amaphuzu alandelayo:

Ukuhlolwa kweJar:Nquma ukucaciswa okungcono kakhulu kanye nomthamo ngokuhlolwa kwembiza. Ekuhlolweni kwembiza, kancane kancane wandise umthamo we-polyacrylamide, bheka umphumela we-flocculation, futhi unqume umthamo olungile.

Ilungiselela i-PAM Aqueous Solution:Njengoba i-anionic PAM (APAM) kanye ne-nonionic PAM (NPAM) inesisindo se-molecular ephakeme namandla anamandla, i-anionic polyacrylamide ivamise ukwakhiwa ibe yisisombululo esinamanzi esinengxube engu-0.1% (ebhekisela kokuqukethwe okuqinile) namanzi angenawo usawoti, ahlanzekile angathathi hlangothi. Khetha amabhakede afakwe ngoqweqwe lwawo, i-aluminium ebiyelwe, noma amabhakede epulasitiki esikhundleni seziqukathi zensimbi njengoba ama-ayoni ensimbi edala ukuwohloka kwamakhemikhali ayo yonke i-PAM. Ngesikhathi sokulungiselela, i-polyacrylamide idinga ukufafazwa ngokulinganayo emanzini anyakazayo futhi ishiswe ngendlela efanele (<60°C) ukuze kusheshiswe ukuncibilika. Lapho kuncibilika, kufanele kukhokhwe ukunakwa ekwengezeni umkhiqizo ngokulinganayo futhi kancane kancane kusincibilikisi ngezinyathelo ezinyakazayo nezokushisa ukuze kugwenywe ukuqiniswa. Isixazululo kufanele silungiswe ezingeni lokushisa elifanele, futhi ukugunda kwemishini okude futhi okuqinile kufanele kugwenywe. Kunconywa ukuthi i-mixer ijikeleze ku-60-200 rpm; ngaphandle kwalokho, kuzodala ukuwohloka kwe-polymer futhi kuthinte umphumela wokusetshenziswa. Qaphela ukuthi isixazululo se-PAM samanzi kufanele silungiswe ngokushesha ngaphambi kokusetshenziswa. Ukugcina isikhathi eside kuzoholela ekwehleni kancane kancane kokusebenza. Ngemuva kokwengeza isisombululo se-flocculant aqueous ekumisweni, ukugqugquzela okunamandla isikhathi eside kuzobhubhisa ama-flocs akhiwe.

Izidingo Zomthamo:Sebenzisa idivayisi yokudosa ukwengeza i-PAM. Esigabeni sokuqala sokusabela kokwengeza i-PAM, kuyadingeka ukwandisa amathuba okuxhumana phakathi kwamakhemikhali namanzi ukuze aphathwe ngangokunokwenzeka, ukwandisa ukugqugquzela, noma ukwandisa izinga lokugeleza.

Izinto Okufanele Uziqaphele Lapho Ungeza I-PAM

Isikhathi Sokuqedwa:Izinhlobo ezihlukene ze-PAM zinezikhathi ezihlukile zokuqedwa. I-Cationic PAM inesikhathi esifushane sokuhlakazeka, kuyilapho i-PAM ye-anionic ne-nonionic inesikhathi eside sokuhlakazeka. Ukukhetha isikhathi esifanele sokuchithwa kungasiza ukuthuthukisa umphumela we-flocculation.

Umthamo kanye nokugxila:Umthamo ofanelekile uyisihluthulelo sokuthola umphumela omuhle kakhulu we-flocculation. Umthamo oweqile ungase ubangele ukujiya okweqile kwama-colloid nezinhlayiya ezimisiwe, zenze izinsalela ezinkulu esikhundleni sama-flocs, ngaleyo ndlela kuthinte ikhwalithi yamanzi angcolile.

Izimo Zokuxuba:Ukuqinisekisa ukuxuba okwanele kwe-PAM namanzi angcolile, imishini yokuxuba efanelekile nezindlela kufanele zikhethwe. Ukuxuba okungalingani kungase kubangele ukuchithwa okungaphelele kwe-PAM, ngaleyo ndlela kuthinte umphumela wayo wokugeleza.

Izimo Zemvelo Yamanzi:Izinto zemvelo ezifana nevelu ye-pH, izinga lokushisa, ingcindezi, njll., nazo zizothinta umphumela we-flocculation we-PAM. Ngokuya ngezimo zekhwalithi yamanzi angcolile, le mingcele ingase idinge ukulungiswa ukuze uthole imiphumela emihle.

Ukulandelana Komthamo:Kuhlelo lokudosa olunabenzeli abaningi, kubalulekile ukuqonda ukulandelana kwemithamo kwama-ejenti ahlukahlukene. Ukulandelana kwedosi okungalungile kungase kuthinte ukusebenzisana phakathi kwe-PAM nama-colloid nezinhlayiya ezimisiwe, ngaleyo ndlela kuthinte umphumela we-flocculation.

I-Polyacrylamide(PAM) iyi-polymer eguquguqukayo esebenza ngezindlela ezahlukahlukene, ikakhulukazi ekuhlanzeni amanzi. Ukwandisa ukusebenza kahle kwayo nokugwema ukumosha, kubalulekile ukulandela izinqubo ezifanele zokusebenza. Ngokucubungula ngokucophelela izici ezifana nesikhathi sokuhlakazeka, umthamo, izimo zokuxutshwa, izimo zemvelo zamanzi, nokulandelana kwemithamo, ungasebenzisa ngempumelelo i-PAM ukuze uzuze imiphumela efiselekayo ye-flocculation futhi uthuthukise ikhwalithi yamanzi.
