Polyacrylamide (PAM), ib hom dej soluble polymer, yog lub luag haujlwm tseem ceeb hauv kev kho dej vim qhov hnyav molecular, dej-soluble, kev tswj ntawm molecular hnyav thiab ntau yam kev hloov kho.
PAM thiab nws cov derivatives tuaj yeem siv los ua cov flocculants zoo, tus neeg sawv cev thickening, tus neeg saib xyuas txo qis, dav siv hauv kev ua dej, ntawv ua, roj av, thee, geology, kev tsim kho thiab lwm yam kev lag luam.
Hauv cov dej hauv av, dej thiab dej phwj tuaj, impurities thiab cov pa phem feem ntau muaj ntau yam uas me me dhau los nyob hauv qab lub ntiajteb txawj nqus.
Vim tias tej yam ntuj tso sedimentation tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, nrog kev pab ntawm cov tshuaj ua kom lub zog ntawm cov cuab yeej siv tau siv hauv kev tsim khoom. Piv txwv li, PAM molecule absorbs ntawm ob peb hais thiab ua floc loj, yog li ntawd, kev sib hais haum ntawm cov khoom yog nrawm.
Piv nrog rau cov inorganic flocculant, PAM muaj ob peb yam tseem ceeb:ntau ntau yam rau ntau yam kev mob, kev ua haujlwm siab, ntau npaum li cas, tsawg sludge generated, yooj yim tom qab kho. Qhov no ua rau nws yog qhov zoo tshaj plaws flocculant.
