Polyacrylamide
I-Polyacrylamide iyi-polymer eqondile, umkhiqizo uhlukaniswe kakhulu waba yimpuphu eyomile nama-colloidal amafomu amabili. Ngokwesisindo sayo samangqamuzana, ingahlukaniswa ibe isisindo esiphansi samangqamuzana (<1 million), medium molecular weight (2 ~ 4 million) and high molecular weight (> .7 million) Ngokuya ngesakhiwo sayo ingahlukaniswa - ionic, i-anion ne-cationic. Ukwahlukaniswa kwamanzi (i-HPAM) yohlobo lwe-anion. Iketanga eliyinhloko le-polyacrylamide liqukethe inani elikhulu lamaqembu e-amide, anokusebenza okuphezulu kwamakhemikhali, futhi angashintshwa ukukhiqiza okuphuma kokuningi kwe-polyacrylamide. Imikhiqizo isetshenziswe kabanzi ekwenzeni iphepha, ukucubungula amaminerali, ukukhipha uwoyela, ukusansimbi, izinto zokwakha, ukwelashwa kwendle nezinye izimboni. Njengesithambisi, i-ejenti yokumiswa, isimame sobumba, i-ejenti yokuhambisa uwoyela, i-ejenti yokunciphisa ukulahleka kwamanzi kanye ne-ejenti yokuqina, i-polyacrylamide isetshenziswe kabanzi ekubhoneni, ekwenzeni i-acidification, ekuqhekekeni, ekuxhumeni amanzi, ekuqiniseni, ekubuyiseleni uwoyela wesibili nasekuvuseleleni uwoyela ophakeme.

Isicelo
Ukuphrinta nokudaya ukwelashwa kwamanzi angcolile
Ukuphrinta nokudaya ukwelashwa kwamanzi amdaka, esikhundleni samasikoji wesiko aphansi wendabuko, ahlobene nomthamo wendabuko omkhulu we-coagulant, ukusebenza kahle kwe-coagulation kuphakeme, izimo ze-ph zinhle ngokulandelayo: 8.0.
2.Papermaking ukwelashwa kwamanzi angcolile
Ukwelashwa kwamanzi angcolile okwenza amaphepha, okusetshenziswa njenge-coagulant esikhundleni se-polyaluminum chloride, i-aluminium sulphate, njll., Kungasetshenziswa futhi njengokuchelela udaka lokwenziwa kwephepha.
Ukupakisha
25kgs net kraft isikhwama nge kk isikhwama ngaphakathi, noma 1000kgs izikhwama ngobuningi.
