Polyacrylamide faiga gaosigae aofia ai le faʻapipiʻiina, polymerization, granulation, faʻamago, malulu, tuʻimomomo ma afifiina. O mea mata e ulu atu i totonu o le fagu tui e ala i le paipa, faʻaopoopo mea faʻapipiʻi tutusa e faʻafefiloi tutusa, malulu i le 0-5 ℃, o mea mata e auina atu i le ulo polymerization e ala i le nitrogen deoxygenation, faʻaititia le okesene i le tusa ma le 1%, faʻaopopo le initiator mo polymerization, pe a maeʻa le polymerization, o le poloka paʻu ua tipiina, auina atu i le pelletizer faʻamago mo granulation. O mea faʻamago e tuʻuina atu i le faiga o le tuʻimomomoina ma le suʻeina mo le tuʻimomomoina. A maeʻa ona tuʻimomomoina, e ulufale le mea i totonu o le faʻapipiʻiina o mea mo le afifiina ma fausia ai le oloa maeʻa.
Polyacrylamidegaosiga faagasologa e lua laasaga
Monomer metotia gaosiga
O le gaosiga o le acrylamide monomer e faʻavae i luga o le acrylonitrile e pei o mea mata, i lalo o le gaioiga o le faʻamaina o le faʻamalama e maua ai le oloa mama o le acrylamide monomer, pe a maeʻa le faʻafefeteina o le acrylamide monomer, o lenei monomer o le mea mataʻutia mo le gaosiga o le poly444 acrylamide.
Acrylonitrile + (vai/vai) → tuufaatasi → acrylamide mama → moli → faamamaina → acrylamide faamamaina.
Polyacrylamide vaifofo vai e faʻaaogaina e fai ma mea mata mo le gaosiga. I lalo o le gaioiga a le initiator, o le tali polymerization e faia. A maeʻa le tali, o le polyacrylamide gum poloka na gaosia e tipiina, faʻamago, faʻamago ma nutimomoia, ma mulimuli ane ua saunia le oloa polyacrylamide. O le faiga autu o le polymerization. I le faagasologa o togafitiga mulimuli ane, e tatau ona gauai atu i le malulu masini, faʻaleagaina vevela ma fesoʻotaʻiga, ina ia mautinoa ai le mamafa mole mole ma le vai solubility o polyacrylamide.
Acrylamide+ vai (initiator/polymerization) → polyacrylamide gum poloka → granulation → faʻamago → nutimomoia → polyacrylamide oloa
