Ke khetha mofuta oa Polycerlamide joang?

Polycerlaymide(Pam) hangata e ka khetholloa ho li-anionic, ho hlonama le ho se ratehe ho ea ka mofuta oa ion. E sebelisoa haholo bakeng sa ho shapuoa ka kalafo ea metsi. Ha o khetha, mefuta e fapaneng ea metsi a litšila e ka khetha mefuta e fapaneng. U hloka ho khetha Pam e nepahetseng ho latela litšobotsi tsa hau. Ka nako e ts'oanang, u lokela ho hlakisa hore na Polycerlaym e ​​tla eketsoa le morero oo u batlang ho o etsa ka ho e sebelisa.

Matšoao a botekgeniki ka kakaretso a kenyelletsa boima ba bilcular, hoye, litaba, masene a masala a litšila ao u lokelang ho a pheralla.

1. Boima ba 'mele / Viscosity

Polycrylalamide e na le mefuta e mengata ea li-alecular, ho tloha ho tlaase ho ea holimo haholo. Boikutlo ba molengcar bo ama ts'ebetso ea polymers likopo tse fapaneng. Velyar ea Molecular Velecerlayide e sebetsa haholoanyane ts'ebetsong hobane litulo tsa bona tsa polymer li le telele ebile li ka hokahanya likopano tse ling hammoho.

Kelello ea tharollo ea Pam e phahame haholo. Ha ionization e tsitsitse, boima ba bilcular ba Polycryarmide, e leng vicosuble ea tharollo ea eona. Lebaka ke hobane ketane ea macromolecular ea polyacryarlamide e telele ebile e tšesaane, le ho hanela ho sisinyeha ka tharollo e kholo haholo.

2. Tekanyo ea hydrolysis le iicinity

IOICIOY ea Pam e na le tšusumetso e kholo ea phello ea eona, empa boleng ba eona bo loketseng bo latela mofuta le lintho tse tloaelehileng, 'me ho na le litekanyetso tse fapaneng tse nepahetseng maemong a fapaneng. Ha matla a lithollo tsa thepa e phephetsoeng a le holimo (taba e sa tloaelehang), e leng ionicity ea Pam e sebelisitsoeng e lokela ho ba holimo, ho seng joalo e lokela ho ba tlase. Ka kakaretso, boemo ba Anion bo bitsoa mokhoa oa hydrolysis, 'me tekanyo ea ion hangata e bitsoa degree ea cation.

Tsela ea ho Khetha Polycerlaymideho latela khatello ea lililitara le e emisitsoeng ka metsing. Kamora ho utloisisa matšoao a kaholimo, ho khetha pem e loketseng?

1. Utloisisa Mohloli oa Seea

Taba ea mantlha, re tlameha ho utloisisa mohloli ona, tlhaho, sebopeho, litaba tse tiileng, joalo-joalo.

Ka kakaretso, Mandic Polycryrolide e sebelisoa ho phekola phollo ea manyolo, le anionic Polycerlayide e sebelisoa ho phekola sello se sa tloaelehang. Ha PH e phahame, Caic Polycerlayide ha ea lokela ho sebelisoa, le ha, Polyc polycerlayide ha ea lokela ho sebelisoa. Acidity e matla e etsa hore e be ea bohlokoa hore e sebelise li-anionic Polycrmide. Ha litaba tse thata tsa ho lla hoa phahama, palo ea polyacryrolode e sebelisoang e kholo.

2. Khetho ea Ionicity

Bakeng sa ho thella hoo ho hlokang ho lekanngoa ka kalafo e fapaneng ea li-pefocculalliide ea nang le liteko tse nyane tsa Polycrmide

3. Khetho ea boima ba limolek'hule

Ka kakaretso, boima ba limolek'hule tsa limolycryryryry ba lihlahisoa tsa Polycryryide, empa ba sebelisa, ho na le boima ba limolek'hule tsa sehlahisoa, matla a ho sebetsa hantle. Ka tšebeliso e khethehileng, boima bo loketseng ba limolek'hule tsa Polycryarmide bo lokela ho etsoa ho latela indasteri ea 'nete ea lits'ebeletso, lisebelisoa tsa boleng ba metsi le kalafo.

Ha u reka le ho sebelisa PAM ka lekhetlo la pele, ho khothalletsoa ho fana ka boemo bo itseng ba seemahale ho moetsi oa lipalesa, 'me re tla khothaletsa mofuta o loketseng oa sehlahisoa. Le mehlala ea mangolo bakeng sa tlhahlobo. Haeba u na le boiphihlelo bo bongata kalafong ea hau ea likhopolo-taba, ha u re bolella litlhokahalo tse khethehileng, likarolo tsa kopo le lits'ebetso tsa pame tseo u li sebelisang, 'me re tla re ama ka leihlo le letona.
