Dispersant, flocculant
Lub polyacrylamide dispersant nyob rau hauv daim ntawv kev lag luam feem ntau yog ib tug cationic polyacrylamide nrog ib tug kuj tsis tshua muaj molecular hnyav.Vim tias nws cov saw hlau molecular muaj cov carboxyl pawg, nws muaj qhov cuam tshuam rau qhov tsis zoo ntawm cov fibers, tuaj yeem ua kom cov viscosity ntawm cov ntaub so ntswg, ua rau muaj kev cuam tshuam rau fiber ntau, thiab tuaj yeem txhim kho cov ntawv sib xws, thiab nws yog qhov ua tau zoo. dispersant rau ntev fibers.Amphoteric polyacrylamide yog siv los ua flocculant rau kev kho dej hauv kev lag luam ntawv.Nws cov pab pawg amide tuaj yeem tsim cov ntawv cog lus hydrogen nrog ntau yam khoom hauv cov dej khib nyiab, yog li nws tuaj yeem nqus cov khoom tawg hauv dej ua ke thiab sib sau ua ke.Facilitates daws thiab pom cov khoom siv.Piv nrog rau lwm cov inorganic flocculants, amphoteric polyacrylamide muaj qhov zoo ntawm ntau yam ua tiav, kev siv tsawg dua hauv kev tsim khoom, kev daws teeb meem ceev ceev, tsawg dua cov sludge, thiab yooj yim tom qab kev kho mob, thiab lwm yam, uas tuaj yeem ua tau raws li cov kev cai ntawm kev kho dej khib nyiab sib txawv.
Txhawm rau ua tiav, polyacrylamide ua lub luag haujlwm tseem ceeb hauv kev lag luam ntawv.Nws tuaj yeem siv los ua tus neeg sawv cev ntawm daim ntawv, ntxiv dag zog rau tus neeg sawv cev, dispersant, lim pab, thiab lwm yam. Nws lub hom phiaj yog txhawm rau txhim kho cov ntawv zoo sib xws, txhim kho cov ntawv zoo thiab lub zog ntawm daim ntawv, thiab kuj tseem txhim kho tus nqi khaws cia ntawm cov fillers thiab cov fibers zoo, txo txo qhov poob ntawm cov khoom siv raw, txhim kho pom kev rov qab ua haujlwm zoo thiab txo cov pa phem ib puag ncig.
CPAM yog siv los ua tus neeg sawv cev txhawb zog, los ntawm kev tsim cov ionic bonds ntawm cations thiab anions ntawm cov fibers, nws tuaj yeem raug adsorbed rau ntawm cov ntaub so ntswg, thaum cov pab pawg amide ua ke nrog hydroxyl pawg ntawm fibers los tsim hydrogen bonds, uas txhim kho lub zog khi ntawm fibers.Ua kom cov ntawv muaj zog.Qhov sib ntxiv ntawm APAM ntxiv rau rosin thiab aluminium sulfate kuj tuaj yeem tau txais cov txiaj ntsig zoo dua thaum siv hauv cov ntaub so ntswg, tab sis cov nyhuv txhawb zog ntawm APAM yuav txo qis nrog cov ntsiab lus muab tub lim.
