Indlela yokwengeza i-PAM

I-Polyacrylamide (PAM) iyi-polymer eqondile ene-flocculation, adhesion, i-drag reduction, nezinye izakhiwo.I-Polymer Organic Flocculant, isetshenziswa kabanzi emkhakheni wokwelashwa kwamanzi. Uma usebenzisa i-PAM, kufanele kulandelwe izindlela ezifanele zokusebenza ukuze kugwenywe ukumoshwa kwamakhemikhali.

Inqubo Yokufaka i-PAM

NgobaI-PAM eqinile, idinga ukungezwa emanzini ngemva kokuncibilika. Ngezimfanelo zamanzi ezahlukene, izinhlobo ezahlukene ze-PAM zidinga ukukhethwa, kanye nezixazululo ezilinganiswe ngamanani ahlukene. Uma ufaka i-polyacrylamide, kufanele unake amaphuzu alandelayo:

Ukuhlolwa Kwezimbiza:Nquma imininingwane engcono kakhulu kanye nomthamo ngokusebenzisa izivivinyo zembiza. Ekuhlolweni kwembiza, khulisa kancane kancane umthamo we-polyacrylamide, qaphela umphumela we-flocculation, bese unquma umthamo ofanele.

Ukulungiselela Isixazululo Samanzi se-PAM:Njengoba i-anionic PAM (APAM) kanye ne-nonionic PAM (NPAM) zinesisindo esiphezulu sama-molecule kanye namandla aqinile, i-anionic polyacrylamide ivame ukwakheka ibe yisisombululo samanzi esinokuqukethwe okungu-0.1% (okubhekisela kokuqukethwe okuqinile) kanye namanzi ahlanzekile angenasawoti. Khetha amabhakede e-aluminium afakwe i-enamel, agqitshwe nge-galvanized, noma epulasitiki esikhundleni sezitsha zensimbi njengoba ama-ion ensimbi ekhuthaza ukuwohloka kwamakhemikhali kwayo yonke i-PAM. Ngesikhathi sokulungiselela, i-polyacrylamide idinga ukufafazwa ngokulinganayo emanzini axubayo futhi ifudumale ngendlela efanele (<60°C) ukuze kusheshiswe ukuncibilika. Lapho incibilika, kufanele kuqashelwe ukufaka umkhiqizo ngokulinganayo nangokuhamba kancane esincibilikisini ngezinyathelo zokuxuba nokushisa ukuze kugwenywe ukuqina. Isixazululo kufanele silungiswe ekushiseni okufanelekile, futhi ukugunda okunamandla okwenziwa kufanele kugwenywe. Kunconywa ukuthi i-mixer ijikeleze ku-60-200 rpm; ngaphandle kwalokho, izobangela ukuwohloka kwe-polymer futhi ithinte umphumela wokusetshenziswa. Qaphela ukuthi isixazululo samanzi se-PAM kufanele silungiswe ngokushesha ngaphambi kokusetshenziswa. Ukugcinwa kwesikhathi eside kuzoholela ekwehleni kancane kancane kokusebenza. Ngemva kokufaka isixazululo samanzi se-flocculant ekumisweni, ukuxuba ngamandla isikhathi eside kuzobhubhisa ama-floc asele enziwe.

Izidingo Zokulinganisa:Sebenzisa idivayisi yokulinganisa ukuze wengeze i-PAM. Esigabeni sokuqala sokusabela kokwengeza i-PAM, kuyadingeka ukwandisa amathuba okuxhumana phakathi kwamakhemikhali namanzi ukuze aphathwe ngangokunokwenzeka, andise ukuxuba, noma andise izinga lokugeleza.

Izinto Okufanele Uziqaphele Uma Ufaka i-PAM

Isikhathi Sokuqedwa:Izinhlobo ezahlukene ze-PAM zinezikhathi ezahlukene zokuncibilika. I-Cationic PAM inesikhathi esifushane sokuncibilika, kuyilapho i-anionic ne-nonion PAM zinesikhathi eside sokuncibilika. Ukukhetha isikhathi esifanele sokuncibilika kungasiza ekuthuthukiseni umphumela we-flocculation.

Isilinganiso kanye Nokuhlushwa:Umthamo ofanele uyisihluthulelo sokufeza umphumela omuhle kakhulu wokugobhoza. Umthamo oweqile ungabangela ukujiya ngokweqile kwama-colloid nezinhlayiya ezilengayo, kwakhiwe inhlabathi enkulu esikhundleni sama-floc, ngaleyo ndlela kuthinte ikhwalithi yokungcola.

Izimo Zokuxuba:Ukuqinisekisa ukuxuba okwanele kwe-PAM namanzi angcolile, imishini yokuxuba efanele kanye nezindlela kudingeka kukhethwe. Ukuxuba okungalingani kungabangela ukuhlakazeka okungaphelele kwe-PAM, ngaleyo ndlela kuthinte umphumela wayo wokugoba.

Izimo Zemvelo Zamanzi:Izici zemvelo ezifana nenani le-pH, izinga lokushisa, ingcindezi, njll., nazo zizothinta umphumela we-flocculation we-PAM. Kuye ngezimo zekhwalithi yamanzi amdaka, lawa mapharamitha angadinga ukulungiswa ukuze kutholakale imiphumela emihle kakhulu.

Ukulandelana Komthamo:Ohlelweni lokulinganisa olunama-ejenti amaningi, kubalulekile ukuqonda ukulandelana kokulinganisa kwama-ejenti ahlukahlukene. Ukulandelana kokulinganisa okungalungile kungathinta ukusebenzisana phakathi kwe-PAM nama-colloid kanye nezinhlayiya ezimisiwe, ngaleyo ndlela kuthinte umphumela we-flocculation.

I-Polyacrylamide(PAM) iyi-polymer eguquguqukayo enezinhlelo zokusebenza ezahlukahlukene, ikakhulukazi ekuphathweni kwamanzi. Ukuze wandise ukusebenza kwayo futhi ugweme ukuchitha imali, kubalulekile ukulandela izinqubo zokusebenza ezifanele. Ngokucabanga ngokucophelela ngezinto ezifana nesikhathi sokuncibilika, umthamo, izimo zokuxuba, izimo zemvelo zamanzi, kanye nokulandelana komthamo, ungasebenzisa i-PAM ngempumelelo ukuze ufinyelele imiphumela oyifunayo yokugeleza kwamanzi futhi uthuthukise ikhwalithi yamanzi.
