Cationic Polyacrylamide (CPAM)
Taw qhia
Cationic polyacrylamide yog ib qho polymer (tseem hu ua cationic polyelectrolyte). Vim tias nws muaj ntau pawg neeg nquag, nws tuaj yeem tsim adsorption nrog ntau yam khoom, thiab muaj cov haujlwm xws li turbidity tshem tawm, decolorization, adsorption, thiab adhesion.
Raws li ib tug flocculant, nws yog tsuas yog siv nyob rau hauv cov khoom-kua sib cais txheej txheem, xws li sedimentation, clarification, sludge lub cev qhuav dej thiab lwm yam txheej txheem. Nws yog feem ntau siv rau kev kho cov dej khib nyiab hauv cov dej khib nyiab hauv nroog, cov dej phwj hauv nroog, kev ua zaub mov, thiab lwm yam. Los ntawm nws cov nyhuv coagulation muaj zog, impurities yog condensed rau hauv loj flocs thiab yog li sib cais los ntawm kev ncua.
Cia thiab ceev faj
1. Tsis muaj tshuaj lom, yooj yim soluble hauv dej thiab yooj yim noo noo nqus rau caking.
2. Txaws ntawm tes thiab tawv nqaij yuav tsum tau ntxuav nrog dej tam sim ntawd.
3. Kev cia kub kom zoo: 5 ℃ ~ 40 ℃, yuav tsum tau muab cia rau hauv cov ntim thawj hauv qhov chaw txias thiab qhuav.
4. Kev npaj cov kua dej polyacrylamide tsis haum rau kev khaws cia ntev. Nws cov nyhuv flocculating yuav txo qis tom qab 24 teev.
5. Tsawg-hardness dej nrog nruab nrab PH ntau 6-9 yog pom zoo kom yaj polyacrylamide. Kev siv cov dej hauv av thiab cov dej rov siv dua uas tseem muaj ntsev ntau yuav txo cov nyhuv flocculating.
Daim ntawv thov
Cationic polyacrylamide(CPAM) yog ib hom dej-soluble polymer uas muaj ntau yam kev siv, feem ntau hauv kev kho dej, kev kho dej khib nyiab, thiab ntau yam kev lag luam. Nov yog qee qhov kev siv cationic polyacrylamide:
Kev kho dej:CPAM feem ntau yog siv rau hauv cov chaw kho dej kom tshem tawm cov khib nyiab, cov organic teeb meem, thiab lwm yam kab mob los ntawm dej. Nws pab nyob rau hauv flocculation thiab sedimentation txheej txheem, cia cov hais los nyob rau hauv thiab tsim loj aggregates uas yuav yooj yim tshem tawm.
Kev kho dej khib nyiab:Hauv cov chaw kho dej khib nyiab, CPAM yog siv los txhim kho kev ua haujlwm ntawm cov txheej txheem sib cais cov kua dej xws li sedimentation, flotation, thiab pom. Nws pab tshem tawm cov pa phem thiab impurities los ntawm cov dej khib nyiab ua ntej nws tawm mus rau ib puag ncig.
Papermaking:Hauv kev lag luam papermaking, nws tuaj yeem siv los ua tus neeg saib xyuas lub zog qhuav thiab kev pab khaws cia. Txhim kho cov ntawv zoo thiab txuag nqi. Nws tuaj yeem tsim hluav taws xob hluav taws xob ncaj qha nrog inorganic ntsev ions, fibers, organic polymers, thiab lwm yam, txhawm rau txhim kho lub cev lub zog ntawm daim ntawv, txo cov fiber ntau, thiab ua kom cov dej pom. Kuj tseem siv tau rau kev kho dej dawb. Nyob rau tib lub sijhawm, nws muaj qhov pom tseeb flocculation cuam tshuam thaum lub sijhawm deinking.
Mining thiab Mineral Processing:CPAM yog siv nyob rau hauv mining thiab ntxhia ua hauj lwm rau cov khoom-kua sib cais, dewatering ntawm sludge, thiab tailings kho. Nws pab kom paub meej cov txheej txheem dej, rov ua kom cov zaub mov muaj txiaj ntsig, thiab txo qhov cuam tshuam ib puag ncig ntawm kev ua haujlwm tsuas.
Kev lag luam roj thiab roj:Hauv kev lag luam roj thiab roj, CPAM yog siv rau hauv cov av nkos drilling, cov kua dej tawg, thiab txhim kho cov txheej txheem roj rov qab. Nws pab tswj cov kua dej viscosity, txhim kho cov dej ntws zoo, thiab txo qhov tsim kev puas tsuaj thaum lub sijhawm ua haujlwm drilling thiab tsim khoom.
Av Stabilization:CPAM tuaj yeem siv rau hauv av stabilization thiab yaig tswj hauv kev tsim kho, kev tsim kho, thiab kev ua liaj ua teb. Nws txhim kho cov qauv av, txo cov av yaig, thiab txhim kho kev ruaj ntseg ntawm embankments thiab slopes.
Kev lag luam Textile:CPAM yog ua haujlwm nyob rau hauv kev lag luam textile rau kev kho dej khib nyiab, dyeing, thiab sizing txheej txheem. Nws pab tshem tawm cov khib nyiab, cov xim, thiab cov impurities los ntawm cov ntaub ntawv pov tseg, kom ua raws li cov kev cai ib puag ncig.
Municipal Solid Waste Management:CPAM tuaj yeem siv rau hauv lub nroog cov khoom pov tseg kev tswj xyuas cov dej ntws ntawm cov sludge, kev kho cov dej khib nyiab pov tseg, thiab tswj cov ntxhiab tsw.
