Polyacrylamideyog cov dej-soluble linear polymer tsim los ntawm dawb radical polymerization ntawm Acrylamide Monomers. Nyob rau tib lub sijhawm, hydrolyzed polyacrylamide kuj yog cov dej polymer kev kho mob flocculant, uas tuaj yeem nqus tau
Tshem tawm cov nplais hauv dej, ua lub luag haujlwm hauv kev sib txuas thiab bridging ntawm cov ntsiab lus, ua kom cov flocs loj, thiab ua kom nrawm nrawm ntawm nag lossis daus.
Polymer phpaFeem ntau suav nrog peb hom anionic, cationic thiab tsis-ionic, thiab ntawm no, Pam polyacrylamide yog subdivided rau hauv cov qauv sib txawv.Hauv lub ntsej muag ntawm ntau hom kev polyacrylamide, tsis yog cov kws tshaj lij yuav poob rau hauv qab no:
Qhov tsis to taub 1: qhov siab dua cov molecular hnyav / ionicity, zoo duaAnionic Polyacrylamide Feem ntau muaj ntau yam qauv xws li ntawm 3 lab rau 22 lab raws li kev hnyav molecular, thaumCationic Polyacrylamidemuaj ntau yam qauv xws li 30% txog 70%.
Qhov tseeb, kev xaiv ntawm polyacrylamide flocculant nrog sib txawv moleculant hnyav / ionicity muaj qhov sib txawv zoo hauv kev kho cov dej ua kom zoo. Cov koob tshuaj ntau rau cov nyhuv zoo tshaj plaws yog qhov tsawg heev, thiab yog tias cationic pam tshaj li qee qhov ntau, nws yuav ua rau cov tsis zoo. Yog li no, cationic polymer msds yog qhov tsim nyog los txiav txim siab cov qauv kev lag luam tshwj xeeb ntawm kev lag luam, dej ua kom zoo thiab lwm yam kev mob.
Tsis to taub 2: siv tib homPamrau tib hom dej khib nyiab
Piv txwv li, tib lub papermaking wastewater kuj tseem muaj qhov sib txawv, chromacicity teeb meem tuaj yeem daws txhua yam dej, thiab txhua yam dej phwj tuaj yeem ua raws. Polyacrylamide hauv cov hmoov yog tsim nyog los xaiv tus qauv los ntawm kev kuaj me me, yog li kom ua tiav qhov kev cuam tshuam zoo ntawm tsawg dua thiab tus nqi qis.
Tsis to taub 3: ntau npaum li cas ntau npaum li cas, qhov zoo dua
Nyob rau hauv ib txwm muaj xwm txheej yuav nce ntxiv nrog kev nce ntawm cov neeg qaug dej qaug zog, tab sis yog tias cov neeg flocculant yuav dhau los ua kev ruaj khov, thiab hais tias cov viscimity tsis kam ntawm kev ncua colloid hauv dej yuav nce ntxiv. Qhov kev siv tshuaj zoo tshaj plaws yog tau txais los ntawm kev sim tshwj xeeb raws li cov ntsiab lus ntawm cov khib nyiab tshem tawm.
Dab Neeg 4: Lub sijhawm nrawm dua lossis lub sijhawm ntev dua, qhov zoo dua
Yog tias lub nrawm nrawm nrawm dhau thiab lub sijhawm ntev dhau, cov khoom loj ntawm cov khib nyiab yuav tawg
Rau hauv cov khoom me me, thiab cov lus uas tuaj yeem ua haujlwm nag yuav raug tawg ua kom tawg uas tsis tuaj yeem ua ntej.
Tsis to taub 5: lub nrawm nrawm yog qeeb dhau los yog lub sijhawm luv heev
Yog tias qhov nrawm qeeb dhau thiab lub sijhawm luv luv heev, cov flocculant tsis tuaj yeem tiv thaiv cov flocculant kev faib tawm ntawm cov flocculant tsis zoo li qub, uas yog qhov ntau dua Tsis txaus ntseeg ua si lub luag haujlwm ntawm cov flocculant.
Tasfing 6: cations,tus muaj peev xwm, thiab tsis yog-ions yog ruam ruam
Qhov kev xaiv ntawm theem pib feem tsis meej. Tus nqi sib txawv ntawm cation, anion thiab tsis yog-ion yog loj me ntsis, thiab tsis muaj txoj kev pib los ntawm cov kev taw qhia dav dav lossis xaiv cov qeb tsis ncaj ncees lawm. Hauv kev siv cov kev siv, nws kuj tuaj yeem yog cov kwv yees li ntawm:
Cationic Polyacrylamide yog qhov tsim nyog rau flocculation, sedimentation, decolorization, organic sludge dewatering, thiab lwm yam; pawg dej phwj tuaj
Aidions yog haum rau cov dej phwj tuaj, sedimentation, dewatering, thiab lwm yam, thiab muaj peev xwm siv tau rau lub cev qhuav dej ntawm inorganic sludge;
Nonacrymrylamideyog haum rau cov av hauv av khaws cia, cov kua qaub tsis muaj zog qaug cawv, sedimentation, lub cev qhuav dej, thiab lwm yam.
