Factory Direct Muag Polyacrylamide PAM rau Oilfield Wastewater Treatment Drilling Fluid Papermaking
Polyacrylamide yog ib hom kab dej-soluble polymer, thiab yog ib qho ntawm ntau hom kev siv dej-soluble polymer compounds. PAM thiab nws cov derivatives tuaj yeem siv los ua cov flocculants zoo, cov thickeners, cov ntawv txhim kho thiab cov kua cab txo cov neeg ua haujlwm, thiab Polyacrylamide tau dav siv hauv kev kho dej, ntawv ua, roj av, thee, mining, metallurgy, geology, textile, kev tsim kho thiab lwm yam kev lag luam. .
Cov polyacrylamide yog dej-solution siab polymer nrog zoo flocculanting kev ua si yuav txo tau cov kev sib txhuam resistanca ntawm cov kua.
1.Flocculation: PAM tuaj yeem ua rau cov khoom raug tshem tawm los ntawm hluav taws xob nruab nrab, ua lub luag haujlwm ntawm flocculation.
2.Adhesiveness: Cov impurities tuaj yeem ua ke ua ke kom ua rau hauv qab.
3.Thickening Agent: Nyob rau hauv neutralizing acidic tej yam kev mob muaj thickening nyhuv, yog hais tias tus nqi PH yog ntau tshaj 10 PAM yooj yim hydrolysis.
Polyacrylamide (PAM) muaj xws li anion (APAM), cation (CPAM), non-ionic (NPAM) thiab zwitterion (ACPAM). Polyacrylamide feem ntau yog siv rau hauv cov thee ntxhua khaub ncaws, luam ntawv thiab dyeing Hoobkas, ua liaj ua teb, dej phwj kho cog, roj teb, tsom zeb, thiab lwm yam.
Anion Polyacrylamide (APAM)yog ib qho ntawm feem ntau siv dej-soluble polymers. Anionic polyacrylamide (APAM) suav nrog: ultra siab molecular hnyav (tshaj 25 lab), siab molecular hnyav (txog 20 lab), nruab nrab molecular hnyav (kwv yees li 16 lab), Cov ntsiab lus ntawm cov khoom muaj zog tshaj 89 feem pua.
Nonionic Polyacrylamide (NPAM)suav nrog: qhov nruab nrab molecular hnyav (tshaj 15 lab), qhov hnyav molecular tsawg (txog 8 lab), Cov ntsiab lus ntawm cov khoom ntau tshaj 89 feem pua.
Cation Polyacrylamide (CPAM)yog ib hom polyacrylamide uas muaj cov pab pawg neeg ua haujlwm zoo, xws li amino lossis quaternary ammonium, uas ua rau nws muaj txiaj ntsig zoo hauv kev khi nrog cov khoom tsis zoo, xws li av nplaum, silt, thiab cov organic teeb meem hauv dej.
Amphoteric polyacrylamide (ACPAM), vim nws cov molecular suav nrog cationic thiab anionic pawg, nthuav tawm cov kev ua tau zoo tshaj ntxiv rau cov yam ntxwv ntawm cationic flocculants. Hom flocculant no tuaj yeem siv nyob rau hauv ntau yam ntawm pH qhov tseem ceeb, muaj peev xwm pom ntau dua thiab qis dua cov khoom qab zib noo noo. Nws kuj tseem siv tau rau cov kua qaub leaching ntawm ores los yog kom rov qab tau cov hlau muaj txiaj ntsig los ntawm cov kua qaub catalysts uas muaj hlau.

Kev sim Flocculation:
Kev siv thaj chaw:
Kev kho dej phwj tuaj:
Lub nroogKev kho dej phwj tuaj, kev ua zaub mov, metallurgy, dyeing kev lag luam, kev lag luam ntxhia, kev lag luam qab zib thiab ntau yam kev kho dej khib nyiab.
Raws li cov khoom ntawm kev tshem tawm cov teeb meem, concentration thiab flocculation kev ua tau zoo ntawm polyacrylamide, nag lossis daus tuaj yeem muab faib ua: ntuj nag lossis daus, flocculation nag lossis daus hauv cheeb tsam. Qhov concentration ntawm cov khoom raug tshem tawm hauv cheeb tsam nag lossis daus yog siab dua (ntau dua 5000mg / L), thiab kev sib haum xeeb ntawm cov khoom raug cuam tshuam los ntawm lwm cov khoom nyob ib puag ncig, thiab cov txheeb ze ntawm cov khoom tsis hloov pauv, ua rau tag nrho cov dab dej, thiab muaj qhov tseeb. av nkos-dej interface ntawm lawv thiab cov dej ntshiab. Regional sedimentation tshwm sim nyob rau hauv ob qho tib si theem nrab sedimentation tank thiab sludge thickening tank.
Kev lag luam ntawv:
Kev lag luam ntawv tuaj yeem siv rau daim ntawv qhuav lub zog tus neeg saib xyuas, tus neeg saib xyuas tuav, lim pab, txhim kho daim ntawv zoo thiab muaj peev xwm ntau lawm.
APAM kuj tseem siv tau rau hauvtxheej txheem papermaking.Cov ntawv thov tseem ceeb ntawm polyacrylamide hauv kev lag luam ntawv muaj ob yam: ib qho yog txhawm rau txhim kho tus nqi khaws cia ntawm cov additives, pigments, thiab lwm yam, txhawm rau txo qis cov khoom siv raw thiab ib puag ncig muaj kuab paug; Qhov thib ob yog los txhim kho lub zog ntawm daim ntawv.
Vim lub hom phiaj sib txawv ntawm PAM siv hauv kev lag luam ntawv, cov kev xav tau rau cov txheeb ze molecular hnyav thiab carboxyl pawg ntsiab lus (degree ntawm hydrolysis) ntawm cov polymer kuj txawv. Yog li APAM muaj kev siv dav hauv cov txheej txheem papermaking.
Roj kev lag luam:
Polyacrylamide yog dav siv nyob rau hauv oilfield tshuaj xws li av nplaum los tiv thaiv expansion agents, thickeners rau roj teb acidification, thiab oily wastewater kho cov neeg ua hauj.
Feem ntau, PAM feem ntau siv nyob rau hauv lubroj tebvim nws cov hauj lwm zoo li flocculant thiab nws lub peev xwm los txhim kho cov khoom rheological ntawm cov kua dej drilling. Txawm li cas los xij, CPAM kuj tseem tuaj yeem ua tau zoo hauv qee cov ntawv thov thiab tej zaum yuav nyiam nyob rau qee kis. Qhov kev xaiv ntawm hom polyacrylamide siv yog nyob ntawm qhov kev xav tau tshwj xeeb thiab cov xwm txheej ntawm kev lag luam roj.
