Molecular hnyav:Ranges ntawm anionic polyacrylamide dav los ntawm ntau pua txhiab rau ntau dua nees nkaum lab. Qhov siab dua cov molecular hnyav, qhov ntau dua cov kev daws teeb meem viscosity thiab lub zog flocculation kev ua tau zoo.
Stability:Anionic Polyacrylamide yog ruaj khov nyob rau hauv nruab nrab thiab alkaline tej yam kev mob. Hydrolysis yuav tshwm sim nyob rau hauv acidic tej yam kev mob. Kev kub siab (siab dua 60 degree) lossis cov oxidants tuaj yeem ua rau molecular chains breakage thiab kev ua phem.
Anionic PolyacrylamideYog ib txoj kab polymer tsim los ntawm Copolymerization ntawm Acrylamide Monomer nrog anionic monomers xws li acionic monomers xws li Acater Acid (AA) lossis sodium acrylate. Cov molecular chart ntawm cov polymer no muaj ntau tus ntawm cov pawg carboxyl ({ Cov pab pawg anionic no muab nws ua kom tau cov dej solubility thiab tus nqi them nqi. Nws cov roj molecular tuaj yeem qhia tawm raws li: -}}}}} {{{{{{{-, Qhov twg m thiab n sawv cev rau℃ntawm polymerization ntawm acrylamide thiab anionic monomers feem. Los ntawm kev kho cov feem sib piv ntawm ob, cov qib anionic ntawm cov khoom (feem ntau yog 10% -80%) tuaj yeem hloov tau.

Kev Siv thiab Kev Ceev Faj
Cov txheej txheem tshem tawm
• Kaus: Siv cov dej ntshiab (zam kev siv dej uas muaj impurities lossis siab tawv).
Confrressration: Npaj ib qho 0.1% -0.3% aqueous daws (siab dua cov molecular hnyav, qis dua ntawm kev xav tau).
• Cov kauj ruam:
①slowly sprinkle lub reagent thaum stirring (kev sib hloov ceev 60-200 rpm) kom tsis txhob agglomeration.
② Txuas ntxiv txoj hlua khi rau 30-60 feeb kom txog thaum tiav kev sib nrauj (dej kub 20-30℃tuaj yeem nrawm tuaj yeem nrawm tuaj yeem nrawm tuaj yeem nrawm yuav ua kom nrawm muaj peev xwm nrawm).
Kev daws teeb meem yuav tsum tau siv nyob rau hauv 24 teev tom qab kev sib cais; Tsis txhob muaj ntev - sij hawm cia raws li nws yuav ua rau kev ua phem.
Ntsej Muag
• Muab tshuaj: txiav txim siab los ntawm kev ntsuam xyuas beaker raws li cov dej ua tau zoo. Feem ntau, nws yog 0.1-10mg / l.
• Kev siv tshuaj ua ntu zus: rau kev kho cov khoom siv pov tseg, xws li PAC) ua ntej, tom qab ntawd ntxiv apam, thiab ob qho tib si yuav tsum tau sib cais los ntawm 1-2 feeb.
• Tej yam kev sib xyaw: qhov kev sib xyaw ua ke yuav tsum tau ua kom huv si, xws li ua yeeb nkab sib xyaw ua ke (xws li} ceev} ceev} ceev dlring) kom tsis txhob cuam tshuam cov molecular.
Zais Cov Lus Qhia
• Tus nqi: Cov ntawv thov kev zoo tshaj plaws yog nruab nrab rau Alkaline (PH 7-14). Acidic tej zaum yuav ua rau qhov txo qis hauv flocculation.
• Qhov kub thiab txias: qhov kev sib cais ua qeeb qeeb thaum cov dej qis dua 5 degree, thiab qis dua 60℃yuav ua rau molecular saw breakage.
• Cov Cheebtsam Kom Zoo: Hlau ions hauv dej (xws li ca²⁺, mg²⁺) tej zaum yuav cuam tshuam rau flocculation. Kho cov tshuaj lossis siv lwm tus neeg sawv cev ua ke.
Cia thiab Kev Nyab Xeeb
• Cia: Cov khw ntim khoom txias rau qhov chaw txias thiab qhuav, tiv thaiv los ntawm noo noo thiab tshav ntuj, nrog lub neej txee ntawm 2 xyoos.
• Kev Tiv Thaiv Kev Nyab Xeeb: Cov khoom hmoov yog nquag ya mus. Thaum ua haujlwm, hnav lub qhov ncauj qhov ntswg thiab hnab looj tes; Yog tias hu rau daim tawv nqaij lossis qhov muag, tam sim ntawd yaug nrog dej ntau.

AnionicpolyacrylamideSiv dav hauv kev xaiv me me, metallurgy, thee ntxuav, khoom noj khoom haus, steel, kho kua thiab khib nyiab dej. APAM kuj tseem siv tau rau cov roj zoo thiab roj tawm hauv cov roj kev lag luam, thiab cov kev pab ua haujlwm thiab ua kom muaj kev lag luam hauv papermaking.
