Kev teeb tsa cov kev sib xyaw rau cov ntawv thov anionic polyacrylamide

Anionic polyacrylamide feem ntau yog siv rau kev ua kom cov dej phwj tuaj yeem ua kom muaj zog, nws muaj cov yam ntxwv ntawm polymer electrolyte hauv nruab nrab thiab alkaline nruab nrab, rhiab rau cov ntsev electrolytes, thiab cov hlau ions kim heev tuaj yeem sib txuas ua cov gel tsis yaj, uas feem ntau yog siv rau cov dej tsim hauv tsev, kev kho dej phwj hauv kev lag luam thiab hauv nroog, thiab kuj tseem siv tau rau kev ua kom cov dej phwj tsis muaj zog.

Peb qhov chaw siv tseem ceeb ntawm anionic polyacrylamide:

Hauv kev lag luam casting thiab hlau tsim khoom, nws yog siv rau kev ntxuav cov roj ntxuav dej hauv qhov cub qhib qhov cub, kev ntxuav cov dej khib nyiab hauv cov nroj tsuag hmoov metallurgy thiab cov nroj tsuag pickling, kev ntxuav cov electrolytes thiab kev ntxuav cov kua pov tseg electroplating.

Hauv kev tsuas, nws yog siv rau kev ntxuav dej thee thiab cov tailings flotation, kev lim dej huv thee, tailings (slag) dehydration, flotation tailings clarification, concentrate thickening thiab filtration, potassium alkali kub yaj thiab flotation ua kua clarification, fluorite thiab barite flotation tailings clarification, raw brine rau kev ua ntsev, sludge dehydration clarification thiab phosphate mine rov qab kho dej.

Hauv kev kho dej khib nyiab hauv nroog thiab kev lag luam, nws yog siv los txhim kho kev tshem tawm cov khoom seem, BOD thiab phosphate hauv cov dej khib nyiab. Los ntawm kev ntxiv 0.25mg / L hydrolyzed polyacrylamide rau hauv lub tank dej khib nyiab thawj zaug, qhov kev tshem tawm ntawm cov khoom seem thiab BOD tuaj yeem nce mus txog 66% thiab 23%, raws li. Los ntawm kev ntxiv 0.3mg / L anionic polyacrylamide rau hauv lub tank dej khib nyiab thib ob, qhov kev tshem tawm ntawm cov khoom seem thiab BOD tuaj yeem nce mus txog 87% thiab 91%, raws li, thiab qhov kev tshem tawm phosphorus tuaj yeem nce ntxiv los ntawm 35% txog 91%. Hauv kev kho dej haus thiab cov dej khib nyiab hauv tsev, nws yog siv rau kev ua kom pom tseeb ntawm qhov chaw, kev ua kom pom tseeb ntawm cov dej khib nyiab thiab kev hloov kho lim.

Qhov solubility ntawm anionic polyacrylamide npaj tau qhia:

1, siv rau hauv cov dej phwj tuaj, qhov concentration ntawm 0.1% pom zoo

2, ua ntej muab cov hmoov nchuav rau hauv dej kais, thiab do ntawm qhov ceev nruab nrab ntawm 40-60 RPM kom cov polymer yaj tag nrho hauv dej ua ntej nws tuaj yeem ntxiv.

3, Thaum lub sijhawm sim, siv 100ml dej khib nyiab, ntxiv 10% polyacrylamide kua, thiab maj mam do, siv lub koob txhaj tshuaj kom maj mam ntxiv PAM kua, 0.5ml txhua zaus, raws li qhov loj ntawm cov paj alum tsim tawm thiab qhov ze ntawm cov flocculant, qhov meej ntawm supernitant, qhov nrawm ntawm sedimentation, qhov koob tshuaj kom txiav txim siab tus neeg sawv cev tsim nyog.
