Anionic polyacrylamide feem ntau yog siv los ua kom muaj zog flocculation ntawm cov dej phwj tuaj, nws muaj cov yam ntxwv ntawm polymer electrolyte nyob rau hauv nruab nrab thiab alkaline nruab nrab, rhiab heev rau ntsev electrolytes, thiab tus nqi siab hlau ions tuaj yeem hla mus rau hauv cov gel insoluble, uas yog siv rau kev tsim khoom hauv tsev. dej, kev lag luam thiab hauv nroog kev kho dej phwj tuaj, thiab tseem tuaj yeem siv rau cov dej tsis muaj dej.
Peb qhov chaw tseem ceeb ntawm anionic polyacrylamide:
Hauv kev lag luam casting thiab hlau tsim, nws yog siv rau kev ua kom huv ntawm cov roj ntxuav dej hauv qhov qhib lub qhov cub, qhov kev qhia meej ntawm cov dej khib nyiab hauv cov hmoov metallurgy cov nroj tsuag thiab cov nroj tsuag pickling, purification ntawm electrolytes thiab qhia meej ntawm electroplating pov tseg kua.
Nyob rau hauv mining, nws yog siv rau thee ntxuav dej clarification thiab flotation tailings, ntxuav thee pom, tailings (slag) lub cev qhuav dej, flotation tailings clarification, concentrate thickening thiab pom, poov tshuaj alkali kub yaj thiab flotation ua kua clarification, fluorite thiab barite flotation tailings clarification , raw brine rau ntsev ua, sludge dehydration clarification thiab phosphate mine rov kho dej.
Hauv kev kho dej khib nyiab hauv nroog thiab kev lag luam, nws yog siv los txhim kho kev tshem tawm cov khib nyiab, BOD thiab phosphate hauv cov dej khib nyiab.Los ntawm kev ntxiv 0.25mg / L hydrolyzed polyacrylamide rau thawj cov dej khib nyiab pov tseg, cov nqi tshem tawm ntawm cov teeb meem tshem tawm thiab BOD tuaj yeem nce mus rau 66% thiab 23%, feem.Los ntawm kev ntxiv 0.3mg / L anionic polyacrylamide rau cov dej khib nyiab thib ob, qhov kev tshem tawm ntawm cov teeb meem tshem tawm thiab BOD tuaj yeem nce mus rau 87% thiab 91%, feem, thiab cov nyhuv tshem tawm phosphorus tuaj yeem nce ntxiv ntawm 35% mus rau 91%. .Hauv kev kho cov dej haus thiab cov dej khib nyiab hauv tsev, nws yog siv rau kev ua kom pom tseeb ntawm qhov chaw, kev nthuav dav ntawm cov dej khib nyiab thiab kev lim dej.
Solubility ntawm anionic polyacrylamide npaj tau qhia:
1, siv nyob rau hauv dej phwj dej, qhov pom zoo ratio concentration ntawm 0.1%
2, ua ntej sib npaug ntawm cov hmoov hauv cov kais dej, thiab do ntawm qhov nruab nrab ceev ntawm 40-60 RPM kom cov polymer tag nrho yaj hauv dej ua ntej nws tuaj yeem ntxiv.
3, Thaum lub sij hawm kev sim, noj 100ml dej khib nyiab, ntxiv 10% polyacrylamide tov, thiab maj mam do, siv ib tug syringe maj mam ntxiv PAM tov, 0.5ml txhua lub sij hawm, raws li qhov loj ntawm lub generated alum paj thiab qhov ze ntawm lub flocculant, qhov clarity ntawm tus supernitant, tus nqi sedimentation, ntau npaum li cas los txiav txim tus neeg sawv cev tsim nyog.
