Iinkcukacha

Iithegi

I-Polyacrylamide yipolymer ehambelanayo, imveliso yahlulwe kakhulu ibe ngumgubo owomileyo kunye neefom ezimbini ze-colloidal. Ngokomlinganiselo wayo we-molecular weight, inokwahlulwa ibe yi-low molecular weight (<1 yezigidi), i-molecular weight medium (2 ~ 4 million) kunye ne-high molecular weight (> .7 million) - ionic, anion kunye cationic. Ukuchithwa kwamanzi (HPAM) yohlobo lweanion. Ikhonkco eliphambili le-polyacrylamide iqulethe inani elikhulu lamaqela e-amide, kunye nomsebenzi ophezulu wekhemikhali, kwaye inokuguqulwa ukuvelisa ezininzi ze-polyacrylamide. Iimveliso zisetyenziswe ngokubanzi kwi-papermaking, i-mineral processing, i-oyile, i-metallurgy, izinto zokwakha, ukucocwa kwamanzi amdaka kunye namanye amashishini. Njenge-lubricant, i-agent yokunqunyanyiswa, i-stabilizer yodongwe, i-oyile yokufuduka, i-arhente yokunciphisa ilahleko yamanzi kunye ne-agent e-thickening, i-polyacrylamide isetyenziswe ngokubanzi ekwembeni, i-acidification, i-fracturing, i-pluging yamanzi, i-cementing, ukubuyiswa kweoli yesibini kunye nokubuyisela i-oyile ephakamileyo.

Isicelo

1.ukuprinta kunye nokudaya unyango lwamanzi amdaka

Ukuprintwa kunye nokudaya unyango lwamanzi amdaka, endaweni yee-coagulants ze-molekyuli ephantsi, xa kuthelekiswa nedosi yemveli enkulu ye-coagulant, ukusebenza kakuhle kokudibanisa kuphezulu, iimeko ezifanelekileyo ze-ph ngolu hlobo lulandelayo: 8.0.

2.Ukwenza iphepha lokucocwa kwamanzi amdaka

Ukwenziwa kwephepha lokucocwa kwamanzi amdaka, asetyenziswa njenge-coagulant endaweni ye-polyaluminium chloride, i-aluminium sulfate, njl.
