Polyacrylamide (PAM) / nocon polyacrylamide / cation polyacrylamide / ionic polyacrylamide, Kev kho cov dej ntws hauv cov dej, polyacrylamide thiab tuaj yeem faib ua kom sib tov ntawm cov kua: anionic, cationic, customeric thiab amphoteric cov khoom lag luam.
Polyacrylamide yog ib qho dawb hmoov particle, uas tuaj yeem ua feem ntawm cov zauv uas muaj feem cuam tshuam nrog kev nce ntawm cov neeg txheeb ze ntawm cov polymer. Pam yog insoluble nyob rau hauv feem ntau cov kuab tshuaj hauv cov organic, xws li formaldehyde, ethanol, acetone, ether, etc.
Polyacrylamide yog dej-soluble polymer lossis polyelectrolyte, cov dej lim tshuaj. Muaj qee cov pawg ntawm cov pawg ua ke hauv qab roob molecular, uas tuaj yeem tshem tawm cov khoom hauv qab, yog li ntawd cov me nyuam tuaj yeem ua kom muaj cov flocs loj. Yog li ntawd, polyacrylamide tuaj yeem nrawm cov khib nyiab tshem tawm. Lub sedimentation ntawm nruab nrab cov lus muaj cov txiaj ntsig pom tseeb ntawm kev ua kom pom tseeb qhov tseeb ntawm kev daws teeb meem thiab kev txhawb nqa kom pom kev.
Polyacrylamide muaj cov tshuaj lom tsis tau muaj kuab lom acrylamide monomer. Hauv kev haus dej haus rau cov dej hauv kuv lub teb chaws, qhov nyiaj pub tshaj plaws yog 0.01mg / l. Txhawm rau tiv thaiv qhov kev cuam tshuam ntawm polyacrylamide, qhov chaw cia kub ntawm nws cov kua aqueous yuav tsum tau tswj tsis tau kom siab dua 40 ° C. Txhawm rau tiv thaiv kev ua tshav ntuj, xws li sodium thiocyanate, sodium nitrite, thiab muaj peev xwm ntxiv rau kev daws. Polyacrylamide cov hmoov hmoov yuav tsum tau ntim rau hauv cov nruas nruas nrog polyethylene ntim lossis muab ntim rau kom tiv thaiv kom muaj cov av noo siab.
Ua kua ua kua polyacrylamide yuav tsum tau ntim thiab tom qab ntawd muab tso rau hauv cov ntoo ntoo lossis hlau ntoo. Lub sijhawm khaws cia yog li 3 txog 6 hlis. Nws yuav tsum tau do ua ntej siv. Qhov ntsuas kub yuav tsum tsis siab tshaj 32 ° C thiab qis dua 0 ° C.
Tuam Tshoj Dadmac, Poly Dadmac tuaj yeem siv dav hauv cov dej khib nyiab thiab dej ua kom zoo li sludge thickening thiab dewatering. Nws tuaj yeem txhim kho cov dej kom pom tseeb ntawm qhov tshuaj tsis tshua muaj. Nws muaj cov haujlwm zoo uas nrawm nrawm qhov sedimentation tus nqi. Nws yog haum rau ntau hom ph 4-10.
Cov khoom no tseem tuaj yeem siv rau hauv cov dej khib nyiab, cov ntawv ua khib nyiab dej, roj av thiab roj nchuav roj thiab hauv nroog dej phwj tuaj.
Kev Lag Luam Kev Lag Luam: Coj cov qhua tuaj noj mov ua lub neej, coj tau zoo, lub luag haujlwm, cov khoom lag luam hauv ntiaj teb no txhua tus neeg ua haujlwm yuav ua haujlwm ua ke thiab mus tom ntej ua ke.
Peb cov hom phiaj tseem ceeb yuav muab peb cov neeg muaj kev sib raug zoo thiab ua haujlwm zoo rau cov kws tshaj lij, peb zoo siab tos txais cov koom haum, muab cov koom haum uas muaj zog rau txhua qhov chaw hauv lub ntiaj teb Txhawm rau kov nrog peb thiab thov kev koom tes rau kev sib koom tes.
Kev tshaj lij Tuam Tshoj Tuam Tshoj Polyacrylamide Poly Dadmac, Pdadmac 26, nyob rau hauv thiaj li yuav tsum tau ua raws li cov neeg ua haujlwm hauv lub tsev ntawm "Zoo, kev ua haujlwm tau zoo thiab credit" thiab siv zog rau sab saum toj Tam sim no qauv thiab cov hmoov txhuas. Peb sov siab txais tos koj tuaj xyuas peb lub tuam txhab thiab kev koom tes.
