Polyacrylamideyog dej-soluble linear polymer tsim los ntawm dawb radical polymerization ntawm acrylamide monomers.Nyob rau tib lub sijhawm, hydrolyzed polyacrylamide kuj tseem yog cov tshuaj polymer dej kho flocculant, uas tuaj yeem nqus tau.
tshem tawm cov khoom hauv dej, ua lub luag haujlwm hauv kev sib txuas thiab kev sib txuas ntawm cov khoom sib txuas, ua kom cov khoom zoo tsim cov flocs loj, thiab ua kom nrawm nrawm ntawm nag lossis daus.
Polymer PHPAfeem ntau suav nrog peb hom anionic, cationic thiab non-ionic, thiab ntawm lub hauv paus no, pam polyacrylamide tau muab faib ua cov qauv sib txawv.Nyob rau hauv lub ntsej muag ntawm ntau hom polyacrylamide, cov uas tsis yog kws tshaj lij yuav poob rau hauv cov kev nkag siab yuam kev hauv qab no:
Kev nkag siab yuam kev 1: Qhov siab dua qhov hnyav molecular / ionicity, qhov zoo duaAnionic polyacrylamide feem ntau muaj ntau yam qauv xws li 3 lab rau 22 lab raws li qhov hnyav molecular, thaumcationic polyacrylamidemuaj ntau yam qauv xws li 30% mus rau 70%.
Qhov tseeb, kev xaiv ntawm polyacrylamide flocculant nrog qhov sib txawv molecular hnyav / ionicity muaj qhov sib txawv hauv kev kho mob ntawm cov dej sib txawv.Qhov ntau npaum li cas rau cov txiaj ntsig zoo tshaj plaws yog me me, thiab yog tias cationic pam ntau dhau ntawm qee yam, nws yuav ua rau muaj kev phom sij.Yog li ntawd, cationic polymer msds yog qhov tsim nyog los txiav txim siab cov qauv tsim nyog ntawm polyacrylamide raws li kev lag luam kev lag luam, dej zoo, khoom siv kho mob thiab lwm yam.
Kev nkag siab yuam kev 2: Siv tib homPAMrau tib hom dej khib nyiab
Piv txwv li, tib cov ntaub ntawv pov tseg kuj tseem muaj qhov sib txawv ntawm pH, organic teeb meem, inorganic teeb meem, chromaticity, SS, thiab lwm yam. Tsis yog ib hom polyacrylamide tuaj yeem daws tau txhua yam teeb meem, thiab txhua yam dej phwj tuaj yeem ua raws li txheej txheem.Polyacrylamide hauv POWDER yog tsim nyog los xaiv tus qauv los ntawm kev sim me me, thiab tom qab ntawd sim nws ntawm lub tshuab los txiav txim siab qhov kev pom zoo, thiaj li ua tiav cov txiaj ntsig zoo tshaj plaws ntawm cov tshuaj tsawg dua thiab tus nqi qis.
Kev nkag siab yuam kev 3: Qhov ntau npaum li cas, qhov zoo dua
Nyob rau hauv ib txwm muaj xwm txheej, cov nyhuv flocculation yuav nce nrog qhov nce ntawm cov nyiaj flocculant, tab sis yog hais tias tus nqi ntawm flocculant ntau dhau, lub flocculant yuav dhau los ua ib qho chaw ruaj khov dua, thiab cov viscosity ntawm cov dej yuav nce, kom cov sedimentation tsis kam. ntawm suspended colloid nyob rau hauv dej yuav nce.Qhov ntau npaum li cas yog tau los ntawm kev sim tshwj xeeb raws li cov ntsiab lus ntawm cov khoom raug tshem tawm.
Tswvyim 4: Qhov nrawm nrawm nrawm lossis lub sijhawm ntev dua, qhov zoo dua
Yog hais tias lub stirring ceev ceev heev thiab lub sij hawm ntev heev, cov khoom loj ntawm cov khib nyiab yuav tawg
mus rau hauv me me, thiab hais tias yuav precipitated yuav tawg mus rau hauv hais tias yuav tsis tau precipitated.
Kev nkag siab yuam kev 5: Lub stirring ceev yog qeeb dhau los yog lub sij hawm luv dhau
Yog tias qhov nrawm nrawm dhau thiab lub sijhawm luv luv, flocculant tsis tuaj yeem tiv tauj tag nrho cov khoom siv, uas tsis tsim nyog rau cov flocculant kom ntes cov colloidal hais, thiab cov concentration ntawm cov flocculant tsis sib xws, uas yog ntau dua. unfavorable mus ua si lub luag hauj lwm ntawm flocculant.
Kev tsis nkag siab 6: cations,anions, thiab non-ions yog stupidly tsis meej
Qhov kev xaiv ntawm pawg hauv paus tsis meej.Tus nqi sib txawv ntawm cation, anion thiab non-ion yog me ntsis loj, thiab tsis muaj txoj hauv kev los pib ntawm cov kev taw qhia dav dav lossis xaiv qhov tsis ncaj ncees lawm.Hauv kev siv tswv yim, nws kuj tuaj yeem raug cais raws li:
Cationic polyacrylamide yog tsim rau flocculation, sedimentation, decolorization, clarification, thiab lwm yam. ntawm complex dej zoo, nroog sludge dewatering, organic sludge dewatering, thiab lwm yam.; Tuam Tshoj dej phwj kho mob Cog
Anions yog tsim rau dej phwj flocculation, sedimentation, dewatering, clarification, thiab lwm yam, thiab kuj siv tau rau lub cev qhuav dej ntawm inorganic sludge;
Nonionic polyacrylamideyog tsim rau cov av tuav dej, tsis muaj zog acid dej phwj flocculation, sedimentation, lub cev qhuav dej, thiab lwm yam.
Yixing Cleanwater chemicals Co., Ltd.ltd kuj tau tshwj xeeb hauv kev txhim kho cov khoom tswj hwm thiab QC system kom ntseeg tau tias peb tuaj yeem khaws cov txiaj ntsig zoo hauv lub tuam txhab sib tw hnyav rau Kev Xaiv Loj rau Tuam Tshoj Anionic PAM / Polyacrylamide rau Kev Siv Dej Kho Dej, Nrog rau txoj kev ntseeg ntawm "kev ntseeg, neeg ua ntej", Yixing Cleanwater chemicals Co., Ltd.txais tos cov neeg yuav khoom yooj yim hu lossis e-mail rau peb rau kev koom tes.
