Polyacrylamide
Polyacrylamide yi Polymer yomgama, imveliso ikakhulu yahlulwe ngumgubo owomileyo kunye colloidal iintlobo ezimbini. Ngokwe-avareji yobunzima bayo, inokwahlulwa kubunzima obuphantsi beemolekyuli (<1 yezigidi), ubunzima obuphakathi beemolekyuli (2 ~ 4 yezigidi) kunye nobunzima obuphezulu beemolekyuli (> .7 yezigidi). - ionic, anion kunye ne-cationic. Ukwahlukana kwamanzi (i-HPAM) yohlobo lwe-anion. Ikhonkco eliphambili le-polyacrylamide linenani elikhulu lamaqela e-amide, anemisebenzi ephezulu yamachiza, kwaye anokuguqulwa ukuze kuveliswe izinto ezininzi zepolyacrylamide. Iimveliso zisetyenziswe ngokubanzi ekwenzeni iphepha, ukulungiswa kwezimbiwa, ukukhutshwa kweoyile, isinyithi, izinto zokwakha, unyango lwamanzi amdaka kunye namanye amashishini. Njengesithambisi, iarhente yokumiswa, isomisi somdongwe, iarhente yokufuduswa kweoyile, iarhente yokunciphisa ukulahleka kwamanzi kunye nearhente yokuqina, i-polyacrylamide isetyenziswe ngokubanzi ekubumbeni, kwi-acidification, ekuqhekekeni, ekuplaleni amanzi, ekuqiniseni, ekubuyiseleni ioyile yesibini kunye nokubuyisela ioyile ephezulu.

Ukusetyenziswa
1.printing kunye bokudaya unyango lwamanzi amdaka
Ukuprinta kunye nokudaya unyango lwamanzi amdaka, endaweni yamasiko eemolekyuli eziphantsi, ahambelana nomthamo wemveli omkhulu we-coagulant, ukusebenza kwe-coagulation kuphezulu, iimeko ezifanelekileyo ze-ph ngolu hlobo lulandelayo: 8.0.
Ukucocwa kwamanzi amdaka nge-2
Unyango lwamanzi amdaka ekwenzeni iphepha, olusetyenziswa njengendawo egudileyo endaweni ye-polyaluminum chloride, i-aluminium sulphate, njl.njl.
Ukupakisha
25kgs net okwakhiwa ibhegi kunye pp ibhegi ngaphakathi, okanye 1000kgs iingxowa isambuku.
