Kodi n’chiyani chimapangitsa kuti Polyacrylamide ikhale yabwino kwambiri pa Flocculation?

Polyacrylamideimadziwika kwambiri chifukwa cha kugwira ntchito kwake bwino pokonza flocculation, njira yofunika kwambiri m'mafakitale osiyanasiyana monga kukonza madzi otayidwa, migodi, ndi kupanga mapepala. Polima yopangidwa iyi, yopangidwa ndi acrylamide monomers, ili ndi makhalidwe apadera omwe amaipangitsa kukhala yoyenera kwambiri pakugwiritsa ntchito flocculation.

Choyamba, kulemera kwakukulu kwa mamolekyulu a polyacrylamide ndi chinthu chofunikira kwambiri chomwe chimapangitsa kuti ikhale ndi mphamvu yabwino kwambiri yosuntha. Maunyolo ataliatali a mayunitsi obwerezabwereza a acrylamide amalola kuyanjana kwakukulu ndi tinthu tomwe timayimitsidwa mu yankho. Kapangidwe ka mamolekyulu kameneka kamawonjezera mphamvu ya polima kupanga ma floc akuluakulu komanso okhazikika, omwe ndi magulu a tinthu tating'onoting'ono. Zotsatira zake, polyacrylamide imatha kumangirira pamodzi tinthu tating'onoting'ono bwino, zomwe zimathandiza kuti tikhazikike mwachangu kapena kupatukana ndi gawo lamadzimadzi.

Kapangidwe ka polyacrylamide kosungunuka m'madzi kamawonjezeranso magwiridwe antchito ake osungunuka. Popeza imasungunuka m'madzi, polyacrylamide imatha kufalikira mosavuta ndikusakanikirana mu yankho, kuonetsetsa kuti ikupezeka mofanana mu dongosolo lonse. Khalidweli ndilofunikira kuti pakhale kusungunuka kogwirizana komanso kogwira mtima, chifukwa polima iyenera kukhudzana ndi tinthu tonse tomwe tili mu yankho kuti tipange ma floc.

Kusalowerera kwa mphamvu kwa Polyacrylamide ndi chinthu china chofunikira chomwe chimathandizira kuti flocculation yake igwire bwino ntchito. Polima nthawi zambiri si ya ionic, zomwe zikutanthauza kuti ilibe mphamvu yamagetsi yokwanira. Kusagwirizana kumeneku kumalola polyacrylamide kuyanjana ndi tinthu tambirimbiri, mosasamala kanthu za mphamvu yawo pamwamba. Mosiyana ndi zimenezi, ma polima a anionic kapena cationic akhoza kusankha momwe amagwirira ntchito flocculation, zomwe zimapangitsa kuti asamagwiritsidwe ntchito pa mitundu ina ya tinthu. Kusagwirizana kwa mphamvu kwa Polyacrylamide kumapangitsa kuti ikhale yosinthasintha komanso yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana zoyeretsera madzi.

Kuphatikiza apo, hydrolysis yolamulidwa ya polyacrylamide imatha kuyambitsa magulu a anionic, zomwe zimapangitsa kuti flocculation yake igwire bwino ntchito. Mwa kusintha mawonekedwe a polymer, imakhala yothandiza kwambiri pakukopa ndi kuletsa tinthu tating'onoting'ono tomwe tili ndi ma charge osiyana. Kusinthasintha kumeneku pakuyendetsa ma charge kumalola polyacrylamide kuti igwirizane ndi mitundu yosiyanasiyana ya madzi ndikusintha luso lake losuntha moyenerera.

Kusinthasintha kwa polyacrylamide malinga ndi mawonekedwe ake enieni kumathandizanso kuti igwire bwino ntchito poyendetsa flocculation. Imapezeka m'njira zosiyanasiyana monga emulsions, ufa, ndi ma gels. Kusiyanasiyana kumeneku kumathandiza ogwiritsa ntchito kusankha mtundu woyenera kwambiri kutengera zofunikira za ntchito zawo. Mwachitsanzo, emulsions nthawi zambiri amakondedwa kuti zikhale zosavuta kuzigwira, pomwe ufa umapereka zosavuta kusunga ndi kunyamula.

Pomaliza, magwiridwe antchito abwino kwambiri a polyacrylamide chifukwa cha kulemera kwake kwakukulu kwa mamolekyulu, kusungunuka kwa madzi, kusalowerera kwa ma charge, kusinthasintha kwa ma charge, komanso kusinthasintha kwa mawonekedwe akuthupi. Makhalidwe amenewa pamodzi amapangitsa polyacrylamide kukhala polima yothandiza kwambiri komanso yosinthasintha pothandiza kupanga ma floc okhazikika, motero amathandizira kulekanitsa ndi kuchotsa tinthu tomwe timayimitsidwa kuchokera kumadzimadzi m'njira zosiyanasiyana zamafakitale.
