Nyob rau hauv cov txheej txheem ntawm kev kho dej khib nyiab, nws yuav tsum tau mus dhau ntawm cov txheej txheem ua haujlwm, thiab tom qab raug kuaj kom ua tau raws li tus qauv tso tawm, nws raug tso tawm.Hauv cov txheej txheem no, flocculant plays lub luag haujlwm tseem ceeb.CovFlocculanttuaj yeem flocculate cov teeb meem tshem tawm ntawm me me molecules hauv dej.Tsau, ua kom yooj yim rau lim.Cov hom flocculants kuj nplua nuj heev.Yuav ua li cas xaiv cov flocculant uas haum rau koj kuj tseem ceeb thiab tseem ceeb.Hais txog kev xaiv flocculants, PAM thiab PAC manufacturers muaj cov lus qhia hauv qab no:
Yuav ua li cas xaiv flocculant hauv kev kho dej khib nyiab yuav tsum xaiv raws li cov yam ntxwv ntawm cov dej khib nyiab hauv ib qho kev lag luam tshwj xeeb.Nyob rau tib lub sijhawm, nws tseem nyob ntawm qhov chaw flocculant ntxiv thiab nws siv rau dab tsi.Feem ntau, thaum xaiv ib qho inorganic flocculant yuav tsum xav txog qhov muaj pes tsawg leeg ntawm cov dej khib nyiab, thiab tom qab ntawd xaiv qhov tsim nyog (hlau ntsev, txhuas ntsev lossis hlau-aluminium ntsev, silicon-aluminium ntsev, silicon-ferric ntsev, thiab lwm yam);inorganic polymer flocculants muaj xws li:polyaluminium chloride (PAC), polyaluminium sulfate (PAS), polyaluminium sulfochloride (PACS) thiabpolyferric sulfate (PFS), thiab lwm yam ntawm lawv, ntau tus neeg sawv cev PAC thiab PAS muaj cov yam ntxwv ntawm kev hloov pauv tau zoo rau cov kev hloov pauv hauv cov dej zoo uas tau kho los ntawm cov tshuaj kho dej tsis zoo, cov coagulation zoo thiab purification cuam tshuam, thiab cov nqi qis ntawm cov tshuaj.
Thaum xaiv cov organic flocculant (xws li:Polyacrylamide PAM), nws tsuas yog nyob ntawm seb anionic polyacrylamide, cationic polyacrylamide lossis nonionic polyacrylamide siv.Anionic polyacrylamides yog raws li qib ntawm hydrolysis.Kev xaiv ntawm cations feem ntau yog siv hauv sludge dewatering.Kev xaiv ntawm cationic polyacrylamide yog qhov tseem ceeb heev.Cov chaw kho dej hauv nroog feem ntau siv nruab nrab muaj zog cationic polyacrylamide.Cov cations tsis muaj zog feem ntau yog siv rau sludge lub cev qhuav dej hauv papermaking thiab luam ntawv thiab dyeing nroj tsuag, thiab cov dej khib nyiab feem ntau yog siv.Xaiv cov cations muaj zog thiab lwm yam.Txhua hom dej khib nyiab muaj nws tus yam ntxwv.Tsis yog-ionic polyacrylamide feem ntau yog siv nyob rau hauv tsis muaj zog acidic tej yam kev mob, thiab non-ionic PAM feem ntau yog siv nyob rau hauv printing thiab dyeing factories.
Cov neeg muag khoom kho dejqhia tias kev xaiv ntawm tag nrho cov flocculants no yuav tsum tau txiav txim siab raws li qhov kev xeem.Hauv kev sim, txiav txim siab qhov kwv yees npaum li cas, soj ntsuam qhov flocculation thiab sedimentation ceev, xam cov nqi kho mob, thiab xaiv tus neeg saib xyuas kev lag luam thiab siv tau.
