Polyacrylamideyog cov dej-soluble linear polymer tsim los ntawm cov dawb radical polymerization ntawm acrylamide monomers. Tib lub sijhawm, hydrolyzed polyacrylamide kuj yog ib qho polymer dej kho flocculant, uas tuaj yeem nqus tau
cov khoom me me uas raug dai hauv dej, ua lub luag haujlwm tseem ceeb hauv kev sib txuas thiab txuas ntawm cov khoom me me, ua rau cov khoom me me ua cov flocs loj, thiab ua kom cov nag los sai dua.
Polymer PHPAfeem ntau suav nrog peb hom anionic, cationic thiab non-ionic, thiab ntawm lub hauv paus no, pam polyacrylamide tau muab faib ua ntau hom qauv sib txawv.Nyob rau hauv lub ntsej muag ntawm ntau hom polyacrylamide, cov neeg 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 hnyav molecular / ionicity siab dua, qhov zoo duaAnionic polyacrylamide feem ntau muaj ntau yam qauv xws li 3 lab txog 22 lab raws li qhov hnyav molecular, thaumcationic polyacrylamidemuaj ntau yam qauv xws li ntawm 30% mus rau 70%.
Qhov tseeb, kev xaiv cov polyacrylamide flocculant nrog qhov hnyav molecular / ionicity sib txawv muaj qhov sib txawv loj hauv kev kho cov txiaj ntsig ntawm cov dej zoo sib txawv. Qhov ntau npaum li cas rau qhov zoo tshaj plaws yog me me heev, thiab yog tias cationic pam tshaj qhov ntau yam, nws yuav ua rau muaj kev phiv. Yog li ntawd, cationic polymer msds yog qhov tsim nyog los txiav txim siab qhov qauv tshwj xeeb ntawm polyacrylamide raws li kev lag luam daim ntawv thov tiag tiag, qhov zoo ntawm dej, cov khoom siv kho thiab lwm yam mob.
Kev Nkag Siab Yuam Kev 2: Siv tib homPAMrau tib hom dej khib nyiab
Piv txwv li, cov dej khib nyiab ua ntawv tib yam kuj tseem yuav muaj qhov sib txawv ntawm pH, cov organic matter, cov inorganic matter, chromaticity, SS, thiab lwm yam. Tsis muaj ib hom polyacrylamide tuaj yeem daws txhua yam teeb meem, thiab txhua yam dej phwj tuaj yeem ua raws li Txheej Txheem. Polyacrylamide hauv HMOOV yog qhov tsim nyog los xaiv tus qauv los ntawm kev sim me me, thiab tom qab ntawd sim nws ntawm lub tshuab kom txiav txim siab qhov ntau npaum li cas, yog li ua tiav qhov 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, qhov cuam tshuam ntawm flocculation yuav nce ntxiv nrog rau qhov nce ntawm cov flocculant, tab sis yog tias qhov ntau ntawm flocculant ntau dhau, cov flocculant yuav rov qab los ua ib qho colloid ruaj khov dua, thiab qhov viscosity ntawm cov dej yuav nce ntxiv, yog li qhov kev tiv thaiv sedimentation ntawm cov colloid suspended hauv dej yuav nce ntxiv. Qhov koob tshuaj zoo tshaj plaws tau txais los ntawm kev sim tshwj xeeb raws li cov ntsiab lus ntawm cov khoom suspended.
Cuav 4: Qhov ceev ntawm qhov kev sib tov lossis lub sijhawm ntev npaum li cas, qhov zoo dua
Yog tias qhov kev sib xyaw ceev dhau thiab lub sijhawm ntev dhau, cov khoom loj ntawm cov khoom khov yuav tawg.
ua tej daim me me, thiab cov daim uas tuaj yeem ua rau poob yuav raug tawg ua tej daim uas tsis tuaj yeem poob.
Kev Nkag Siab Yuam Kev 5: Qhov ceev ntawm kev nplawm qeeb dhau los yog lub sijhawm luv dhau
Yog tias qhov ceev qeeb dhau thiab lub sijhawm luv dhau, cov flocculant tsis tuaj yeem tiv tauj cov khoom khov kho tag nrho, uas tsis zoo rau cov flocculant kom ntes cov khoom colloidal, thiab qhov kev faib tawm ntawm cov flocculant tsis sib xws, uas yog qhov tsis zoo dua los ua lub luag haujlwm ntawm cov flocculant.
Kev nkag siab yuam kev 6: cations,cov anions, thiab cov non-ions tsis meej pem
Qhov kev xaiv ntawm cov pawg yooj yim tsis meej. Qhov sib txawv ntawm tus nqi ntawm cation, anion thiab non-ion yog me ntsis loj, thiab tsis muaj txoj hauv kev los pib los ntawm kev taw qhia dav dav lossis xaiv pawg tsis raug. Hauv kev siv tiag tiag, nws kuj tseem tuaj yeem raug cais ua:
Cationic polyacrylamide yog qhov tsim nyog rau flocculation, sedimentation, decolorization, clarification, thiab lwm yam ntawm cov dej zoo, nroog sludge dewatering, organic sludge dewatering, thiab lwm yam.; Tuam Tshoj Dej phwj Kho Cog
Cov anions yog qhov tsim nyog rau cov dej phwj tuaj, kev tso dej tawm, kev tshem dej tawm, kev ua kom pom tseeb, thiab lwm yam, thiab tseem tuaj yeem siv rau kev qhuav dej ntawm cov dej tsis muaj zog;
Cov polyacrylamide uas tsis yog ionicyog tsim rau kev khaws cia dej hauv av, cov dej phwj tsis muaj zog acid flocculation, sedimentation, dehydration, thiab lwm yam.
Yixing cleanwater chemicals co. ltd kuj tau tshwj xeeb hauv kev txhim kho cov khoom tswj hwm thiab QC system kom ntseeg tau tias peb tuaj yeem khaws cia qhov txiaj ntsig zoo hauv lub tuam txhab sib tw hnyav rau Kev Xaiv Loj rau Tuam Tshoj Anionic PAM / Polyacrylamide rau Kev Kho Dej, Nrog rau lub hauv paus ntawm "kev ntseeg, cov neeg siv khoom ua ntej", yixing cleanwater chemicals co., ltd. txais tos cov neeg yuav khoom tsuas yog hu rau lossis xa email rau peb rau kev koom tes.
Kev Xaiv Loj rau Tuam Tshoj Tuam Tshoj soluble manufacturers.
