Polyacrylamideyipolymer enomyinge enyibilikayo emanzini eyenziwe yipolymerization yasimahla ye-acrylamide monomers. Kwangaxeshanye, i-hydrolyzed polyacrylamide ikwayi-polymer yonyango lweflocculant, enokufunxa.
amasuntswana axhonyiweyo emanzini, adlala indima ekudibaniseni nasekuvaleni phakathi kwamasuntswana, enze amasuntswana acolekileyo enze iiflokhi ezinkulu, aze akhawulezise isantya sokuna kwemvula.
Ipolymer PHPAngokuqhelekileyo ibandakanya iintlobo ezintathu anionic, cationic kunye non-ionic, kwaye kwesi siseko, pam polyacrylamide yahlulwe ibe imifuziselo series ezahlukeneyo.Phambi kweendidi ezininzi zepolyacrylamide, abangengabo oochwephesha banokuwela koku kungaqondani kulandelayo:
Ukungaqondi kakuhle 1: Ukuphakama kwe-molecular weight / ionicity, kungconoI-Anionic polyacrylamide ineentlobo ngeentlobo zeemodeli ukusuka kwi-3 yezigidi ukuya kwi-22 yezigidi ngokobunzima bemolekyuli, ngelixacationic polyacrylamideineentlobo ngeentlobo zeemodeli ukusuka kwi-30% ukuya kwi-70%.
Enyanisweni, ukukhethwa kwe-polyacrylamide flocculant ene-molecular weight/ionicity eyahlukileyo inomahluko omkhulu kwisiphumo sonyango lomgangatho wamanzi owahlukileyo. Uluhlu lwedosi yesiphumo esihle kakhulu sincinci, kwaye ukuba i-cationic pam idlula uluhlu oluthile, luya kubangela iziphumo ezibi. Ngoko ke, cationic polymer msds kuyimfuneko ukugqiba imodeli ethile efanelekileyo Polyacrylamide ngokwelona shishini isicelo, umgangatho wamanzi, izixhobo unyango kunye nezinye iimeko.
Ukungaqondi kakuhle 2: Sebenzisa uhlobo olufanayo lwePAMkuhlobo olufanayo lwamanzi amdaka
Umzekelo, amanzi amdaka afanayo enziwe ngamaphepha anokuba nawo umahluko kwi-pH, izinto eziphilayo, izinto eziphilayo, i-chromaticity, i-SS, njl. Akukho nolunye uhlobo lwe-polyacrylamide olunokusombulula zonke iingxaki, kwaye zonke iintlobo zogutyulo zingaba Inkqubo yokuthotyelwa. I-Polyacrylamide kwi-POWDER iyimfuneko ekukhetheni imodeli ngovavanyo oluncinci, kwaye emva koko ivavanye kumatshini ukumisela idosi echanekileyo, ukuze kuphunyezwe isiphumo esihle somthamo omncinci kunye neendleko eziphantsi.
Ukungaqondi kakuhle 3: Okukhona umthamo wedosi, ngcono
Kwiimeko eziqhelekileyo, umphumo we-flocculation uya kwanda ngokunyuka kwexabiso le-flocculant, kodwa ukuba inani le-flocculant ligqithise, i-flocculant iya kuba yi-colloid ezinzileyo kwakhona, kwaye i-viscosity yamanzi iya kwanda, ukwenzela ukuba ukuxhatshazwa kwe-sedimentation. I-colloid emisiwe emanzini iya kwanda. Elona dosi liphezulu lifunyanwa ngokusebenzisa imifuniselo ethile ngokomxholo wezinto eziqinileyo ezinqunyanyisiweyo.
Intsomi yesi-4: Ukukhawuleza kwesantya esishukumisayo okanye ixesha elide, kungcono
Ukuba isantya esishukumisayo sikhawuleza kakhulu kwaye ixesha lide kakhulu, amasuntswana amakhulu aqinileyo aya kwaphulwa
kwiincinci ezincinci, kunye neengqungquthela ezinokuthi zihlanjululwe ziya kuphulwa zibe ngamaqhekeza angenako ukuchithwa.
Ukungaqondi kakuhle 5: Isantya sokuvuselela sicotha kakhulu okanye ixesha lifutshane kakhulu
Ukuba isantya sicotha kakhulu kwaye ixesha lifutshane kakhulu, i-flocculant ayikwazi ukudibanisa ngokupheleleyo amasuntswana aqinileyo, angayisebenzisiyo i-flocculant ukubamba amasuntswana e-colloidal, kunye nokusasazwa koxinaniso lwe-flocculant alufani, olungaphezulu engathandekiyo ukudlala indima ye-flocculant.
Ukungaqondi kakuhle 6: ii-cations,iianions, kunye nee-non-ion azicacanga
Ukukhethwa kweendidi ezisisiseko akucaci. Ukwahlukana kwexabiso phakathi kwe-cation, i-anion kunye ne-non-ion inkulu, kwaye akukho ndlela yokuqala ukusuka kwicala eliqhelekileyo okanye ukhethe udidi olungalunganga. Kwizicelo ezisebenzayo, inokuphinda ihlelwe ngokufanelekileyo ngolu hlobo:
I-Cationic Polyacrylamide ifanelekile ukuxutywa, ukuchithwa kwentlenga, ukuchithwa kwemibala, ukucaciswa, njl., umgangatho wamanzi obunzima, ukuchithwa kodaka lwasezidolophini, ukuchithwa kwe-organic sludge, njl.; China Sewage Treatment Plant
I-Anions ifanelekile ukuthuthwa kwamanzi amdaka, ukuchithwa, ukuchithwa kwamanzi, ukucaciswa, njl., kwaye ingasetyenziselwa ukukhutshwa kwamanzi kwi-sludge ye-inorganic;
Nonionic polyacrylamideilungele ukugcinwa kwamanzi omhlaba, i-asidi ebuthakathaka i-sewage flocculation, i-sedimentation, i-dehydration, njl.
